You have your plot. Your architect has drawn up the plans. The foundation crew is ready. But before the first brick goes down, there is one document you absolutely cannot skip: the commencement certificate.
In Karnataka and across India, building without this document is treated as unauthorised construction. It can lead to stop-work orders, demolition of completed portions, and banks refusing to finance or resell your property. Yet most homeowners and even some first-time developers only find out about it when a problem surfaces.
This guide explains exactly what a commencement certificate is, why it matters, how to obtain one in Karnataka (with Bangalore-specific BPAS portal details updated for 2026), and what documents you need to keep ready.
What Is a Commencement Certificate?
A commencement certificate (CC) is an official document issued by the local municipal or planning authority that gives a developer or property owner formal, legal permission to begin construction on a site.
It is issued only after the authority verifies that:
- The building plan has been sanctioned
- All required No Objection Certificates (NOCs) from departments such as fire, water, sanitation, and electricity are in place
- The plot ownership is legally established through a valid title or conveyance deed
- Environmental clearances (where applicable) have been received
- Structural safety certifications are submitted
Think of it this way: building plan approval says the design is acceptable; the commencement certificate says the site is physically and legally ready for construction to begin.
Any construction started without a commencement certificate is technically unauthorised, regardless of how well-designed the structure is or how many other approvals the developer holds.
Commencement Certificate vs Occupancy Certificate vs Completion Certificate
These three certificates often get confused. Here is how they differ:
| Certificate | When It Is Issued | What It Confirms |
|---|---|---|
| Commencement Certificate (CC) | Before construction begins | Permission to start building |
| Completion Certificate (BCC) | After construction is finished | Building matches the sanctioned plan |
| Occupancy Certificate (OC) | After BCC and safety checks | Building is safe and legal for occupation |
The commencement certificate is the starting document. Without it, neither the BCC nor the OC can be applied for later. It is the foundation of the entire legal documentation chain for any construction project.
Why Is the Commencement Certificate Important?
1. It Makes Your Construction Legally Valid
Constructing without a CC means your building is legally unauthorised. Local authorities including the Greater Bengaluru Authority (GBA) and BBMP have the power to issue stop-work orders, levy penalties, or order demolition of portions built without proper authorisation.
2. Banks Will Not Finance Unauthorised Projects
Most financial institutions and banks require the commencement certificate before sanctioning a construction loan or home loan against an under-construction property. Without it, the lender has no assurance that the project is legally compliant, which increases their risk and typically leads to outright loan rejection.
3. It Protects Homebuyers
For anyone buying a flat or villa in an under-construction project, the CC is the first document to verify. Under RERA, developers are required to disclose their CC before launching sales. If a floor or unit is not mentioned in the CC, it may be illegal or under dispute. A buyer who does not check this is taking a significant financial risk.
4. It Confirms Safety Standards Are in Place
A CC is only issued after structural safety design certificates, fire safety compliance, and foundation stability assessments are submitted. This means a project with a valid CC has already cleared basic structural and safety checks before a single floor is built.
5. It Is Mandatory Under RERA
Under the Real Estate (Regulation and Development) Act, 2016, the commencement certificate is a mandatory disclosure. Developers cannot register a real estate project under RERA, invite advance bookings, or accept deposits from buyers without submitting the CC to the RERA authority. Violation attracts heavy penalties.
Commencement Certificate in Karnataka: How It Works in 2026
Karnataka, and especially Bengaluru, has a specific process for obtaining the commencement certificate. Here is what property developers and homebuilders need to know as of 2026, following the formation of the Greater Bengaluru Authority (GBA), which took over from BBMP in October 2025.
Issuing Authority
Within Bengaluru city limits, the CC is issued by the Greater Bengaluru Authority (GBA), formerly under BBMP. For buildings up to B+G+M+3 floors, the Zonal Assistant Director of Town Planning (ADTP) issues the CC. For taller structures, the Head Office handles it.
Legal basis: Karnataka Municipal Corporations Act, 1976 (Chapter XV) and the Karnataka Town and Country Planning Act, 1961.
The Two-Stage CC System in Bengaluru
Unlike some other states, Bengaluru issues the commencement certificate in two stages:
- Plinth CC – Permits construction up to the plinth level. Issued after the developer submits compliance with initial conditions of the Intimation of Disapproval (IOD) online via the BPAS portal.
- Further CC – Permits continuation of the superstructure. Issued only after a joint site inspection confirms the plinth meets specifications, and after compliance with Further CC conditions is submitted online along with payment of applicable fees.
This two-stage system ensures ongoing compliance rather than a single upfront check, providing additional protection for buyers and lenders.
Is a CC Mandatory for All Buildings in Karnataka?
Not for all buildings. In Bengaluru under GBA/BBMP, the CC is mandatory for:
- All buildings requiring building plan sanction
- Larger residences beyond 1,200 sq ft plot (30×40 ft)
- Apartments and commercial buildings including projects with stilt parking
- BDA-approved projects and BBMP/GBA-approved developments
2025 GBA relaxation: Residential buildings on plots up to 1,200 sq ft (30×40) for up to 3 storeys received relaxed OC and CC requirements. However, building plan approval remains mandatory even for these. Always confirm with your BBMP-registered architect whether a CC is required for your specific plot size and construction type.
Note: Buildings in Gram Panchayat areas follow the GP building licence process and are not covered under the GBA/BBMP CC system.
e-Khata Is Now Mandatory (From July 2025)
A key 2025 update: from July 1, 2025, e-Khata is mandatory for CC applications within GBA/BBMP jurisdiction. If your property does not have an e-Khata, sort that first before beginning the CC application process. Understanding the difference between A Khata and B Khata is essential here – only A Khata properties typically qualify for CC and subsequent approvals.
How to Apply for a Commencement Certificate in Bangalore (Step-by-Step)
Step 1: Engage a BBMP-Registered Architect
Property owners cannot apply for a CC directly. The application must be submitted by a BBMP-empanelled architect through their professional portal credentials on the BPAS system. Choose an architect who is familiar with current GBA building bye-laws, setback norms, and FAR (Floor Area Ratio) requirements.
Step 2: Ensure Building Plan Approval Is in Place
The CC can only be applied for after the building plan has been sanctioned. Your architect will have submitted detailed architectural and structural drawings through the BPAS portal, obtained inter-departmental NOCs through the single-window system, and received the sanctioned plan before reaching this stage.
Step 3: Gather Required Documents
Documents typically required for the CC application include:
- Sanctioned building plan and approved drawings
- e-Khata certificate and extract (mandatory from July 2025)
- Encumbrance Certificate (EC)
- Proof of land ownership – this could be a registered sale deed or conveyance deed, gift deed, or partition deed
- Property tax paid receipts
- NOCs from relevant departments (fire, water, electricity, sanitation) obtained through the single-window system
- Structural safety certificate in design – Form VI(b)
- Subsurface investigation and foundation design certificate – Form VI(a)
- Compliance with IOD (Intimation of Disapproval) conditions
Step 4: Apply Through the BPAS Portal
All CC applications are submitted entirely online through the Building Plan Approval System (BPAS) portal at bpas.bbmpgov.in. Your architect submits compliance with the IOD conditions at the plinth stage. The system generates a demand note for applicable fees. Once payment is made, the Plinth CC is issued online.
Step 5: Site Inspection After Plinth Completion
After construction reaches plinth level, a joint site inspection is arranged through the BPAS system (not arranged separately by the applicant). The inspection confirms compliance with sanctioned plans. Site inspection is system-scheduled, and all compliance submissions must be done online through the portal.
Step 6: Obtain the Further CC
After successful plinth inspection, the architect submits compliance for Further CC conditions and pays the demand note generated by the system. The Further CC is then granted, authorising construction of the superstructure above the plinth.

What Happens If You Build Without a Commencement Certificate?
The consequences of starting construction without a CC are serious and can affect both the developer and the buyer:
- Stop-work orders from local authorities, halting construction midway
- Demolition orders for unauthorised portions built without permission
- Inability to obtain an Occupancy Certificate, which means the building legally cannot be occupied
- Loan rejection – banks will not finance or provide resale mortgages on properties without a CC
- RERA violations – developers who collect advance bookings without a CC face heavy penalties under the Karnataka RERA Act
- Resale difficulties – buyers and their lawyers will flag the missing CC, leading to price negotiations or deal collapses
- Utility connections withheld – permanent electricity and water connections may not be issued for buildings without proper authorisation
For buyers: if a developer cannot produce a commencement certificate, treat it as a serious red flag regardless of how the project looks or how attractive the price is.
How to Verify a Commencement Certificate Online
For projects in Bengaluru, the CC status can be verified through the BPAS portal. Buyers can also request a copy of the CC from the developer and cross-verify the project details, including the sanctioned number of floors and units. Any floor or unit not listed in the certificate may be illegal.
For projects registered under Karnataka RERA (K-RERA), the CC is a mandatory document in the project registration file, which can be viewed on the K-RERA portal.
Validity of the Commencement Certificate
The CC is typically valid until project completion, provided construction strictly follows the sanctioned building plan and no major deviations are made. In practice, the two-stage system in Bengaluru (Plinth CC and Further CC) ties validity to construction milestones rather than a fixed calendar date. Any significant deviation from the approved plan can invalidate the CC and require fresh submissions.
Commencement Certificate and RERA: What Developers Must Know
Under RERA, every developer who intends to sell units in a real estate project must register the project before inviting bookings or accepting deposits. To register, they must submit the commencement certificate issued by the competent authority, the sanctioned plan and layout plan, details of floors and units covered under the CC, and timeline and financial projections.
A developer who collects advance payments or signs agreements before obtaining the CC and RERA registration is in direct violation of the Act. Buyers who have paid in such situations are entitled to refunds with interest under RERA provisions.
Frequently Asked Questions About Commencement Certificate
What is a commencement certificate in simple terms?
A commencement certificate is an official document from the local municipal authority that grants a developer or builder legal permission to begin construction on a plot. It confirms that all pre-construction approvals, NOCs, and safety checks are in place.
Who issues the commencement certificate in Karnataka?
In Bengaluru, the Greater Bengaluru Authority (GBA) issues the CC through the BPAS portal (bpas.bbmpgov.in). For buildings up to B+G+M+3 floors, the Zonal Assistant Director of Town Planning approves it. For taller buildings, the Head Office issues it. In other Karnataka districts, the respective local planning authority or municipal corporation is responsible.
What is the difference between a commencement certificate and an occupancy certificate?
The commencement certificate is issued before construction begins and permits the start of building work. The occupancy certificate is issued after construction is complete and certifies that the building is safe and fit for occupation. One cannot be obtained without the other – the CC is the first step and the OC is the final one in the legal approval chain.
Is e-Khata required for a commencement certificate in Bangalore?
Yes. From July 1, 2025, e-Khata is mandatory for CC applications within GBA/BBMP jurisdiction. Properties without an e-Khata must obtain one before applying for the CC. Read our detailed guide on A Khata vs B Khata to understand which category your property falls under.
How do I verify a commencement certificate is authentic?
For Bengaluru properties, check the project status on the BPAS portal at bpas.bbmpgov.in. For RERA-registered projects across Karnataka, the CC is part of the mandatory document disclosure on the K-RERA portal. Always ask the developer for the CC and match the sanctioned floors and units with what is being sold to you.
Conclusion: The Commencement Certificate Is Non-Negotiable
Whether you are a first-time homebuilder in Mysuru, a developer launching an apartment project in North Bengaluru, or a buyer evaluating a residential project near Devanahalli – the commencement certificate is not a bureaucratic formality. It is the legal foundation on which the entire construction stands.
A property built without a CC cannot be sold cleanly, cannot attract a home loan, cannot get an occupancy certificate, and cannot be legally occupied. For buyers, the CC is the single most important document to verify before committing to any under-construction property. Once construction is complete, understand the full property mutation process in Karnataka to ensure ownership records are updated in your name.
