RERA registration in Kolkata is the mandatory registration of eligible real estate projects and real estate agents with the West Bengal Real Estate Regulatory Authority (WBRERA) before a project is advertised, marketed, booked or sold, or before an agent facilitates any such transaction. The threshold is the nationwide test — land exceeding 500 square metres or more than 8 apartments — and every application is now filed online through the WBRERA portal, with the Authority’s office (the WBRERA Registrar office) at Calcutta Greens Commercial Complex (1st Floor), 1050/2, Survey Park, Kolkata – 700075. West Bengal’s route to WBRERA was unusually long: the state ran its own parallel law, WBHIRA, until the Supreme Court struck it down in 2021, and WBRERA has only been operational since 2023 — which makes confirming which regime an older Kolkata project actually sits under a genuinely city-specific due-diligence step.
1. Why RERA Registration Matters for Kolkata’s Real Estate Market
This guide is maintained by Marcken Consulting LLP, a chartered accountancy and IBBI-registered valuation practice, and was last reviewed on 29 July 2026 against the WBRERA portal, the West Bengal Real Estate (Regulation and Development) Rules, 2021 and the Real Estate (Regulation and Development) Act, 2016 itself.
Kolkata’s development has concentrated heavily along a handful of corridors: the New Town–Rajarhat belt built out by HIDCO as a planned satellite township for IT and ITeS occupiers around Sector V, the older planned township of Salt Lake (Bidhannagar), the EM Bypass corridor linking central Kolkata to the airport, and the southern stretch running through Garia, Sonarpur and toward Baruipur. Metro expansion — particularly the East-West corridor connecting Howrah to Salt Lake — continues to pull both end-user and investor demand toward areas that were considered peripheral a decade ago. Against that growth, RERA registration is the one check a buyer, lender or channel partner can run independently of anything a promoter’s brochure claims: it confirms that the project’s title, approvals, timeline and financial disclosures have actually been filed with a regulator, not merely represented in marketing material.
What makes Kolkata a genuinely distinct case within India’s RERA landscape is regulatory history, not geography. West Bengal did not adopt the central Real Estate (Regulation and Development) Act, 2016 in the way most states did. It instead enacted its own parallel law, the West Bengal Housing Industry Regulation Act, 2017 (WBHIRA), which came into force on 1 June 2018 and was administered by a separate authority, WB HIRA. Home buyers’ groups challenged WBHIRA as an attempt to run a materially weaker regime alongside the central Act, and on 4 May 2021 the Supreme Court agreed, declaring WBHIRA unconstitutional in Forum for People’s Collective Efforts & Anr. v. State of West Bengal & Anr. The Court held that Parliament having already legislated on the subject, a State could not maintain a parallel law covering the same ground without Presidential assent under Article 254 of the Constitution.
West Bengal notified the rules constituting WBRERA on 27 July 2021, but the authority did not become functional immediately — it took until December 2022 for a Chairman to be appointed, and the WBRERA portal went live on 31 January 2023. That makes WBRERA one of the youngest state real estate regulators in the country, roughly 5 to 6 years behind counterparts such as MahaRERA or RERA Karnataka that were operating from 2017. Projects and agents that were originally registered under the now-defunct WBHIRA have since had to come across to WBRERA, and complaints filed under WBHIRA are now heard by WBRERA rather than lapsing. For a promoter, agent or buyer dealing with an older Kolkata project, this is worth checking directly rather than assuming continuity: a registration number or certificate issued before 2023 was almost certainly issued under a regime that no longer exists.
2. The WBRERA Office in Kolkata: Registrar Address, Contact Details and Functions
2.1 The Authority and Its Registrar Office
WBRERA is the state-level regulatory authority established under Section 20(1) of the Act, and it functions from its head office in Kolkata. Since the Authority discontinued offline applications with effect from 15 December 2025, every project registration, agent registration and renewal in West Bengal is filed online through the WBRERA portal and processed by the Authority’s secretariat at that office. In everyday usage, this is what promoters and agents mean by the “RERA Registrar office” in Kolkata: the office where the Authority’s registry receives and scrutinises registration applications, where hearings are held, and where offline complaint submissions are accepted at the counter.
2.2 WBRERA Office Address and Contact Details
| Body | Address | Contact |
|---|---|---|
| West Bengal Real Estate Regulatory Authority (WBRERA) | Calcutta Greens Commercial Complex (1st Floor), 1050/2, Survey Park, Kolkata – 700075 | Phone: 033 2416 0606 Email: rera.wb@gmail.com Portal: rera.wb.gov.in |
| West Bengal Real Estate Appellate Tribunal (WBREAT) | Calcutta Greens Commercial Complex (1st Floor), 1050/2, Survey Park, Kolkata – 700075 (same building) | Phone: 033 2956 0225 Email: wbreat22@gmail.com |
WBRERA also runs a WhatsApp chatbot for basic services — the portal invites users to initiate it by sending Hi to 6292000900.
These details are as published by WBRERA itself; cause lists, hearing schedules and counter arrangements are notified on the portal, so re-confirming there before a visit is sensible — particularly since, with applications now online-only, a physical visit is generally needed only for hearings or offline complaint submission.
2.3 The West Bengal Real Estate Appellate Tribunal (WBREAT)
Appeals against orders of the Authority or of an Adjudicating Officer lie with the West Bengal Real Estate Appellate Tribunal (WBREAT), the appellate body established under the Act for the state. Justice (Retd.) Rabindranath Samanta, formerly a judge of the Calcutta High Court, has chaired WBREAT since March 2024 (position as of mid-2026). The Tribunal’s notices, cause lists and orders are published through the WBREAT section of the WBRERA portal; the mechanics of filing a complaint and the appeal route — including timelines and the promoter pre-deposit rule — are covered in Section 10 below.
2.4 What the WBRERA Office Handles
Beyond receiving and deciding project and agent registration applications and renewals, the Authority’s Kolkata office administers the quarterly project status updates that registered promoters must file through the portal, issues show-cause notices and orders against unregistered marketing and other defaults, hears complaints filed under Section 31, and maintains the public database of registered projects, registered agents and defaulting promoters that anyone can search on the portal. WBRERA has also stated on its portal that a project extension certificate is issued only after any penalty imposed by the Authority has been paid — a practice point promoters seeking extensions should budget for.
3. RERA Applicability: Who Must Register
3.1 The 500 Square Metre / 8-Apartment Threshold
Under Section 3(2)(a) of the Real Estate (Regulation and Development) Act, 2016, registration of a real estate project is not required where the land proposed for development does not exceed 500 square metres, or where the number of apartments proposed does not exceed 8, inclusive of all phases of the project. This is a national threshold, not a West Bengal-specific one. In practice, registration becomes mandatory the moment either limb is crossed — though it is worth noting that authorities and tribunals in different states have not always read the two limbs identically; some treat either condition alone as sufficient, while others have looked for both conditions to be exceeded. A project sitting close to the line on only one limb should not be assumed exempt without a specific check against current WBRERA practice.
Where a project is developed in phases, each phase is treated as a standalone real estate project requiring its own registration. Projects that already held a completion certificate before the Act’s registration requirement took effect, and projects undertaken purely for renovation, repair or redevelopment that do not involve marketing, advertising, selling or new allotment, fall outside the requirement.
3.2 Real Estate Agents: Registration Under Section 9
Section 9 of the Act separately requires every real estate agent to register with WBRERA before facilitating the sale or purchase of any plot, apartment or building forming part of a project registered under Section 3. This applies equally to individual brokers, partnership firms and companies operating as channel partners. Registration is agent-specific rather than project-specific — once granted, it allows the agent to act across any registered project, not only the one named in the original application.
3.3 Projects That Are Exempt
Beyond the size threshold, exemptions generally cover completed projects holding a valid completion certificate, and work limited to repair, renovation or redevelopment without fresh sale or allotment. Government bodies and cooperative housing societies do not receive a blanket exemption — they fall within the registration requirement in the same way as any other promoter once the size threshold is crossed. A further, West Bengal-specific point: a project that was exempt or already dealt with under the now-defunct WBHIRA framework is not automatically exempt under WBRERA, since the two are legally distinct regimes rather than a simple rebrand of one into the other.
4. Project Registration: Process and Documents
4.1 Application Process
A promoter applies for project registration in Form A. The West Bengal Real Estate (Regulation and Development) Rules, 2021 originally contemplated the application being filed in triplicate hard copy until the process was made fully web-based; WBRERA has since gone further than several other states on this point — the Authority has formally discontinued offline applications altogether, with effect from 15 December 2025, making online filing through the WBRERA portal the only route for project registration, agent registration and renewals.
4.2 Documents and Title Due Diligence
Promoters are generally required to submit identity and PAN details, company or LLP incorporation documents, the legal title deed and encumbrance certificate, sanctioned building and layout plans, the commencement certificate where applicable, and draft allotment letter and agreement for sale formats, along with details of the architects, engineers and contractors engaged on the project. Rule 3(1) of the West Bengal Rules adds state-specific items to the checklist: the audited balance sheet for the preceding financial year and income tax returns for the 3 preceding years, a copy of the GST registration, the title deed with the mutation certificate, encumbrance details, and — where the promoter is not the landowner — the owner’s consent together with the collaboration, development or joint development agreement. The portal disclosure requirements additionally call for a land title search report from an advocate with at least 10 years of experience in land matters. Much of this is financial-records work, which is why a promoter’s accountant is usually involved well before the application is filed.
One documentation point is distinctly a Kolkata issue rather than a generic one. Large parts of the older city — Kolkata Municipal Corporation wards 1 to 100, covering areas such as Burrabazar, Ahiritola, Tangra, Kasba, Metiabruz, Garden Reach, Chetla, Topsia, Gouribari and Kalighat, plus roughly 517 acres in Howrah — sit under Thika tenancy, a colonial-era leasehold system in which the state, not the thika tenant, owns the underlying land. Development on Thika land was historically capped at G+2 or 9.5 metres. The West Bengal Thika Tenancy (Acquisition and Regulation) Amendment Act, 2019 introduced statutory “development agreements” between thika tenants and bharatias (sub-tenants) and raised that cap to allow buildings of up to 5 storeys, and a further 2024 amendment brought the Kolkata Metropolitan Development Authority (KMDA) in as a validating authority for such agreements. A promoter assembling land in any of the wards above should confirm whether the parcel is Thika land before assuming a conventional freehold title chain — this issue does not arise in the newer corridors such as EM Bypass, New Town, Salt Lake, Garia or Behala, which sit outside the Thika-designated wards.
4.3 Timeline: The 30-Day Rule
Under Section 5 of the Act, WBRERA must grant or reject a registration application within 30 days of receipt. If it does neither within that window, the project is treated as registered by default. Once granted, the registration certificate and registration number are issued in Form C under Rule 6(1) of the West Bengal Rules. This 30-day, deemed-registration framework is the actual statutory answer to “how long does RERA registration take in Kolkata” — there is no separate, shorter administrative processing time published by WBRERA beyond this statutory window.
4.4 Extension of Registration
Where a project cannot be completed within its declared timeline, the promoter may apply for an extension of registration at least 3 months before the existing registration expires, in Form E. The extension fee is twice the original registration fee. WBRERA communicates a grant of extension in Form F and a rejection in Form D, after giving the promoter an opportunity to be heard. Two limits are worth planning around: under Section 6 of the Act, extension on grounds other than force majeure is capped at 1 year in aggregate — a ceiling WBREAT applied strictly in a 2025 ruling — and WBRERA issues the extension certificate only after any penalty it has imposed on the project has been paid.
5. Real Estate Agent Registration in West Bengal
5.1 Application Process
An individual or entity seeking to operate as a registered real estate agent applies through the WBRERA portal under Section 9(2) of the Act, providing identity and business details, PAN, proof of business address and photographs. Under Rule 10(2) of the West Bengal Rules, the registration fee is Rs 25,000 for an individual applicant and Rs 2,50,000 for an applicant other than an individual, such as a firm, LLP or company — one of the points on which West Bengal departs from the Rs 10,000/Rs 50,000 pattern most other states prescribe, and a figure worth budgeting for before a brokerage entity commits to the entity route rather than individual registrations.
5.2 Validity and Renewal
Agent registration is valid for 5 years from the date of grant. Renewal is applied for in Form J at least 3 months before expiry under Rule 12(1), on the same supporting documents updated for any change in the agent’s details, at a fee of Rs 5,000 for an individual and Rs 50,000 for an applicant other than an individual under Rule 12(2); the renewed registration is valid for a further 5 years. WBRERA can revoke an agent’s registration for cause, and appeals against WBRERA orders — for agents as much as promoters — follow the complaint and appeal route described in Section 10 below.
6. WBRERA Registration Fees
Registration fees for a project are prescribed under the West Bengal Real Estate (Regulation and Development) Rules, 2021 and vary by project category:
| Item | Fee | Provision (WB Rules, 2021) |
|---|---|---|
| Residential project — land not exceeding 1,000 sq m | Rs 10 per sq m | Rule 3(3)(a) |
| Residential project — land exceeding 1,000 sq m | Rs 20 per sq m | Rule 3(3)(a) |
| Commercial or any other project — land not exceeding 1,000 sq m | Rs 50 per sq m | Rule 3(3)(b) |
| Commercial or any other project — land exceeding 1,000 sq m | Rs 100 per sq m | Rule 3(3)(b) |
| Extension of project registration | Twice the original registration fee | Rule 7(2) |
| Real estate agent registration — individual | Rs 25,000 | Rule 10(2) |
| Real estate agent registration — other than individual (firm, LLP or company) | Rs 2,50,000 | Rule 10(2) |
| Renewal of agent registration — individual | Rs 5,000 | Rule 12(2) |
| Renewal of agent registration — other than individual | Rs 50,000 | Rule 12(2) |
| Complaint to the Authority (Form M) | Rs 1,000 | Rule 36(1) |
| Complaint to the Adjudicating Officer for interest and compensation (Form N) | Rs 1,000 | Rule 37(2) |
| Appeal to WBREAT (Form L) | Rs 1,000 | Rule 28(1) |
Two features of the West Bengal schedule differ from what generic multi-state guides often report, and both come straight from the text of the Rules: the project fee is a flat per-square-metre rate that steps up once the land area crosses 1,000 sq m, with no slab-plus-cap formula and no separately prescribed plotted-development rate; and the agent registration fee of Rs 25,000/Rs 2,50,000 is materially higher than the Rs 10,000/Rs 50,000 pattern most other states follow.
All figures above are prescribed under the West Bengal Real Estate (Regulation and Development) Rules, 2021, with the Rs 1,000 complaint fee also stated on the WBRERA portal itself; fee notifications are revised from time to time, so the current schedule on the portal is worth a final check before filing.
7. The Escrow Account and Buyer Protections
7.1 The Separate Account Requirement
Section 4(2)(l)(D) of the Act requires a promoter to deposit 70% of the amounts realised from allottees for a project into a separate bank account, to be used only for the construction and land costs of that project. This is a national provision and applies in West Bengal exactly as it does everywhere else — it is the mechanism intended to stop funds collected for one project being diverted to another.
7.2 Withdrawal Certification: Where a CA’s Role Comes In
Withdrawals from the separate account are not unrestricted; they need to be proportionate to construction progress and supported by certification. This is one of the more direct points of contact between RERA compliance and a Chartered Accountant’s practice — certifying that withdrawals match progress, alongside the project’s architect and engineer, is routine CA work on a registered project, distinct from the promoter’s own statutory audit.
7.3 Interest on Delayed Possession
Where a promoter is liable to pay interest to an allottee under the Act — for a false or incorrect disclosure under Section 12, for a structural defect under Section 14(3), for failure to complete or hand over possession under Section 18, or on an allottee’s claim under Section 19 — Rule 17 of the West Bengal Rules prescribes the applicable rate as SBI’s Prime Lending Rate plus 2%. Because SBI discontinued the Prime Lending Rate as a lending benchmark years ago in favour of the Marginal Cost of Lending Rate (MCLR), the West Bengal Real Estate Appellate Tribunal clarified in a 2025 order that interest should in practice be computed at SBI’s MCLR plus 2%, bringing West Bengal in line with the approach already used in Maharashtra, Karnataka, Tamil Nadu and Assam, while flagging that Rule 17’s text itself still needs formal amendment to catch up with the clarification.
Separately, Rule 18 of the West Bengal Rules puts a hard timeline on refunds: any refund payable by the promoter, together with applicable interest and compensation, must be paid to the allottee within 45 days of the date it becomes due.
Registering a project or need help preparing WBRERA documentation?
A 30-minute conversation is usually enough to scope the work. There is no charge and no obligation.
8. Verifying a Registration on the WBRERA Portal
Before booking a unit, engaging an agent, or relying on a promoter’s representations, the WBRERA portal lets anyone search registered projects by name, promoter or registration number, and registered agents by name or registration number. A project listing shows its registration number, promoter details, sanctioned layout, declared timeline and disclosures filed since registration; an agent listing confirms whether a registration is current, lapsed or revoked. For any project that looks like it may predate 2023, cross-checking the registration number against the WBRERA portal directly — rather than accepting a certificate at face value — is the more reliable way to confirm it was actually carried across from the defunct WBHIRA regime rather than simply referencing an old, no-longer-valid registration.
9. Penalties for Non-Compliance
9.1 Penalties for Promoters
Marketing, booking or selling units in a project that should be registered but isn’t exposes a promoter to a penalty of up to 10% of the estimated project cost under Section 59, and continued non-compliance with the Authority’s subsequent order can escalate to imprisonment of up to 3 years, a further fine, or both. Providing false information at the application stage, or contravening Section 4 — which includes the escrow requirement above — carries a separate penalty of up to 5% of project cost under Section 60, and general contraventions of the Act, rules or regulations fall under Section 61 on similar terms. Where a promoter specifically fails to comply with an order of the West Bengal Real Estate Appellate Tribunal, Section 64 provides for imprisonment of up to 3 years, a fine, or both — distinct from, and more severe than, non-compliance with an Authority order alone.
9.2 Penalties for Real Estate Agents
Facilitating a sale or purchase without the registration Section 9 requires is penalised under Section 62 at up to Rs 10,000 per day, capped by reference to 5% of the property cost involved. Failure to comply with an Authority order attracts a further daily penalty under Section 65. Failure to comply specifically with a WBREAT order is the agent-side equivalent of Section 64 for promoters, but the maximum term under Section 66 is imprisonment of up to 1 year, not 3, alongside a fine.
9.3 Compounding of Offences
Section 70 of the Act allows certain offences to be compounded on payment of a prescribed sum, in place of prosecution, at the court’s discretion — a route intended for the kind of technical or first-instance default a promoter or agent would want resolved without a criminal proceeding running its full course. Rule 35 of the West Bengal Rules fixes the compounding amounts: 10% of the estimated cost of the real estate project for imprisonment under Section 59(2) or Section 64, and 10% of the estimated cost of the plot, apartment or building concerned for imprisonment under Section 66 or Section 68.
10. Filing a Complaint and Appeals: WBRERA, the Adjudicating Officer and WBREAT
Any aggrieved person — an allottee, an association of allottees, or any person affected by a violation of the Act or the Rules — may file a complaint with WBRERA under Section 31, in Form M under Rule 36 of the West Bengal Rules. The fee is Rs 1,000, and filing runs through the complaint module on the WBRERA portal; the portal also sets out an offline route, involving completing the prescribed form, paying the Rs 1,000 fee and submitting the form with the payment receipt at the Authority’s Kolkata office, for complainants who cannot file online.
Where the relief sought is compensation or interest — for a false or incorrect disclosure under Section 12, a structural defect under Section 14(3), failure to complete or hand over possession under Section 18, or a breach of allottee entitlements under Section 19 — the claim is decided by an Adjudicating Officer appointed under Section 71, on a complaint filed in Form N with the same Rs 1,000 fee under Rule 37, following the summary inquiry procedure the West Bengal Rules prescribe. This is the compensation track that runs alongside the Authority’s own powers to direct registration, impose penalties and issue compliance orders.
Appeals from an order of the Authority or the Adjudicating Officer lie to WBREAT within 60 days under Section 44, filed in Form L with a fee of Rs 1,000 under Rule 28 of the West Bengal Rules, with the Tribunal able to condone delay for sufficient cause. A promoter appealing a penalty must first deposit at least 30% of that penalty — or the full amount payable to an allottee, including interest and compensation, where that is what the order requires — under Section 43(5) before the appeal is heard. A further appeal from a WBREAT order lies to the Calcutta High Court within 60 days under Section 58.
11. RERA Compliance Across Kolkata’s Growth Corridors
The practical registration and title issues differ somewhat by where in the Kolkata Metropolitan Area a project sits. The Kolkata Metropolitan Development Authority (KMDA), in place since 1970, coordinates infrastructure and planning across a roughly 1,886 sq km area spanning Kolkata, Howrah, North 24 Parganas, South 24 Parganas and Hooghly — considerably broader than Kolkata Municipal Corporation’s own city limits.
- New Town–Rajarhat — developed by HIDCO and the New Town Kolkata Development Authority (NKDA) under a zoned Action Area I/II/III master plan, and the city’s primary IT/ITeS corridor given its proximity to Sector V. Land here is typically HIDCO or NKDA-allotted, which generally means cleaner, more standardised title documentation than older parts of the city.
- Salt Lake (Bidhannagar) — India’s first planned satellite township and now governed by the Bidhannagar Municipal Corporation; an older, well-established planned development with a different approvals history from New Town.
- EM Bypass corridor — a KMDA infrastructure-led artery connecting central Kolkata toward the airport, with substantial residential and mixed-use development along its length, falling within KMC building-plan jurisdiction for most of its stretch. The WBRERA office itself sits on this corridor at Survey Park.
- Garia, Sonarpur, Narendrapur and the southern belt toward Baruipur — a lower-density, more affordable growth corridor with a mix of KMC and panchayat-area jurisdiction depending on the specific parcel.
- Howrah — across the river and governed by its own municipal corporation, with a section of its own Thika tenancy land (roughly 517 acres) subject to the same title considerations described in Section 4.2.
Across all of these, the single most consistent Kolkata-specific check remains title: whether the land sits within a Thika tenancy ward, whether the sanctioned plan was approved by KMC, KMDA, HIDCO/NKDA or Bidhannagar Municipal Corporation as applicable, and — for any project that has existed since before 2023 — whether it was ever registered under WBHIRA and has since been correctly carried across to WBRERA.
12. Common Compliance Mistakes to Avoid
- Marketing before registration. Advertising, listing, or accepting even a token booking amount before the registration number is granted is itself the Section 59 default — not a preparatory step that becomes compliant once registration follows.
- Assuming an old registration is still valid. A registration number or certificate dated before 2023 needs to be checked against the current WBRERA portal — it may have originated under the now-defunct WBHIRA and require confirmation that it was properly carried across.
- Treating agent registration as project-linked. An agent’s registration is personal to them and covers any registered project, not only the one first mentioned on the application — but it still needs to be current, not merely applied for, before facilitating a transaction.
- Title documentation that doesn’t account for Thika tenancy. Where land falls within the KMC wards or Howrah areas under Thika tenancy, the title chain runs through the state as landowner and a development agreement between the thika tenant and any bharatia, not a conventional freehold sale deed — this needs to be identified early, not discovered during registration.
- Escrow withdrawals without proportionate certification. Drawing from the separate account without certification matching construction progress is a Section 4 compliance gap, not a paperwork formality.
- Leaving an extension application to the last month. Extension needs to be sought at least 3 months before the registration expires, is capped at 1 year in aggregate outside force majeure, and the extension certificate is issued only once any penalty imposed by the Authority has been paid — three constraints that reward early planning.
13. How Marcken Consulting Supports RERA-Adjacent Compliance in Kolkata
13.1 Where a CA Firm Fits in the RERA Process
WBRERA is the statutory authority for registration and regulation under the Act, and Marcken Consulting is not the registering authority and does not act as one. Where our practice intersects with RERA compliance — the work promoters and agents typically have in mind when searching for a RERA registration consultant in Kolkata — is in the areas that sit naturally with a Chartered Accountancy firm’s work: preparing the financial and documentation package that supports a registration application, chartered accountant certification for escrow account withdrawals, and coordinating with the architects, engineers and legal advisors a developer is already working with so that registration, disbursement certification and ongoing compliance move on a consistent timeline.
13.2 Why Promoters and Agents in Kolkata Work With Marcken
Three practical points define how the engagement runs:
- Chartered accountancy and IBBI-registered valuation under one roof. Escrow withdrawal certification and any independent valuation of land, a project or development rights can run within a single engagement rather than across two separate firms.
- Merchant Banker certification, coordinated. Where a transaction also requires a Merchant Banker’s certificate, that certificate is issued by a SEBI-registered Category-I Merchant Banker within the same coordinated engagement.
- Registration-to-certification continuity. The team that assembles the registration documentation is the same team certifying escrow withdrawals and supporting quarterly project updates, so project facts are not re-explained at each stage.
With WBRERA’s own process fully online since 15 December 2025, this work does not depend on where the advisor sits — documentation, certification and follow-up run through the portal and by correspondence, with the statutory filings themselves always made to WBRERA.

Frequently Asked Questions
Is RERA registration mandatory for every real estate project in Kolkata?
Only where the land proposed for development exceeds 500 square metres or the number of apartments exceeds 8, inclusive of all phases, under Section 3(2)(a) of the Act. Smaller projects, completed projects, and pure renovation or redevelopment work without new sale or allotment fall outside the requirement.
How much does WBRERA registration cost?
Under Rule 3(3) of the West Bengal Rules, 2021, residential projects pay Rs 10 per sq m of land where the area does not exceed 1,000 sq m and Rs 20 per sq m where it exceeds 1,000 sq m; commercial or any other projects pay Rs 50 per sq m and Rs 100 per sq m on the same split — there is no slab-plus-cap formula in the West Bengal schedule. Agent registration costs Rs 25,000 for an individual and Rs 2,50,000 for a firm, LLP or company under Rule 10(2), with renewal at Rs 5,000 and Rs 50,000 respectively under Rule 12(2).
Where is the WBRERA office in Kolkata?
At Calcutta Greens Commercial Complex (1st Floor), 1050/2, Survey Park, Kolkata – 700075, on the EM Bypass in south Kolkata. Since 15 December 2025, however, all registration applications are filed online only through rera.wb.gov.in, so a visit is generally needed only for hearings or offline complaint submission.
How long does WBRERA take to process a registration application?
The Authority is required to grant or reject an application within 30 days under Section 5. If it does neither within that period, the project is treated as registered by default.
Do real estate agents in Kolkata need separate RERA registration?
Yes. Under Section 9, any agent facilitating the sale or purchase of a unit in a registered project needs their own registration with WBRERA, regardless of any other professional membership or brokerage licence they hold.
What happened to projects that were originally registered under WBHIRA?
WBHIRA was declared unconstitutional by the Supreme Court on 4 May 2021 and is no longer a functioning regime. Projects and agents that were registered under it have since had to come across to WBRERA, and complaints originally filed under WBHIRA are now handled by WBRERA. Anyone relying on an older WBHIRA-era registration should confirm its current WBRERA status directly on the portal rather than assuming continuity.
What happens if a promoter sells units before registering the project?
It is a default under Section 59, carrying a penalty of up to 10% of the estimated project cost, with imprisonment of up to 3 years or a further fine possible if the promoter continues to disregard the Authority’s order to register.
How do I file a complaint with WBRERA?
Under Section 31, through the complaint module on the WBRERA portal, with a Rs 1,000 fee; an offline route via the Authority’s Kolkata office is also described on the portal. Compensation and interest claims under Sections 12, 14, 18 or 19 go before the Adjudicating Officer, and appeals from either forum lie to WBREAT within 60 days.
Can I verify a project’s RERA registration before booking a unit?
Yes, through the project search function on the official WBRERA portal at rera.wb.gov.in, which shows the registration number, promoter details, sanctioned layout, and disclosures filed since registration.
Do I need a RERA registration consultant in Kolkata?
No consultant is mandatory — WBRERA’s process is self-service through the online portal, and a promoter or agent can file directly. Professional help is typically engaged where the documentation package is heavy (title, sanctioned plans, financial disclosures), where escrow withdrawal certification by a chartered accountant is needed on an ongoing basis, or where quarterly updates, extensions and hearings have to run on a disciplined timeline alongside the project. A RERA registration consultant in Kolkata adds value in that preparation and coordination — not as a substitute for the Authority’s own process.
Is a chartered accountant required anywhere in the RERA process?
Yes, most directly in certifying withdrawals from a project’s separate escrow account in proportion to construction progress, alongside the project’s architect and engineer, before funds can be released for that stage of the project.
