How to Get Building Plan Approved by BBMP

Before preparing building plans, verify your property's zoning classification with BBMP. Bengaluru's Revised Master Plan 2031 designates land as residential, commercial, industrial, or mixed-use. Your proposed construction must comply with the designated land use. Visit the BDA (Bangalore Development Authority) portal or BBMP zonal office to check your property's zoning. Also verify if the property falls under any restricted zones — near lakes (75m buffer), defence areas, airport funnel zones, or heritage structures. Properties near storm water drains (SWD) have specific setback requirements. If your land is in a BDA-approved layout, building plan approval is relatively straightforward. For revenue sites or converted agricultural land, additional approvals from the DC (Deputy Commissioner) office may be required.

BBMP mandates that building plans be prepared and signed by a COA-registered architect. The architect must also be empanelled with BBMP. The plans must include: site plan showing the plot boundaries, setbacks, and access road; floor plans for each level; sectional drawings; elevation drawings; and a structural design certificate from a licensed structural engineer. Setback requirements depend on the road width and building height. For residential buildings on a 30-foot road, the minimum front setback is typically 3 metres, rear 1.5 metres, and side 1.5 metres. Floor Area Ratio (FAR) in Bengaluru for residential zones is typically 1.75-3.25 depending on road width. Your architect calculates the maximum permissible built-up area based on FAR, setbacks, and ground coverage norms.

BBMP requires the following documents for building plan approval: property ownership document (sale deed, gift deed, or partition deed), khata certificate and khata extract (A-khata preferred), up-to-date property tax receipts, encumbrance certificate for the past 13 years, a recent survey sketch from the Survey Department, architect-prepared building plan (3 sets of blue prints), structural engineer certificate, soil test report for buildings above G+2, and photographs of the site from all four directions. If the site is on BDA layout, submit the allotment letter and possession certificate. For sites above 1,000 sq ft, BBMP also requires a tree census report. Non-residential projects additionally need a traffic impact assessment and environmental clearance above certain thresholds.

BBMP uses the Building Plan Approval System (BPAS) — an online portal for submitting building plan applications. Visit sakala.kar.nic.in or the BBMP BPAS portal. Register with your Aadhaar number and mobile. Upload all documents in prescribed format (PDF, max file sizes apply). Enter complete building details: number of floors, total built-up area, plot dimensions, proposed use, and FAR calculations. The system automatically checks basic compliance with building bylaws. You will receive an application reference number. The scrutiny fee is calculated based on the total built-up area and building use — residential attracts lower fees than commercial. For a standard residential G+2 building on a 30x40 site, the combined fees (scrutiny, betterment, labour cess, etc.) typically range from ₹20,000 to ₹80,000.

After submission, a BBMP engineer reviews the plans for compliance with building bylaws, setbacks, FAR, height restrictions, and fire safety norms. If any deviations are found, a scrutiny report with observations is issued online. Common rejection reasons include: setback violations, FAR exceeded, incorrect ownership documents, missing NOCs, and non-compliance with stormwater drain buffer zones. You typically get 15-30 days to rectify and resubmit. After the plan passes scrutiny, BBMP schedules a physical site inspection to verify plot boundaries, access road width, and surrounding structures. The inspecting officer may request additional information or minor plan modifications. Respond promptly to all queries — delays in response push your application to the back of the queue.

Once the plan clears scrutiny and site inspection, BBMP issues the building plan approval order. This includes the approved plan (stamped and signed), conditions of approval, validity period (typically 3-5 years), and a commencement certificate permitting you to begin construction. The approved plan specifies permissible built-up area, height, setbacks, and use. Any deviation during construction is an unauthorised construction and liable for demolition. Before starting construction, display the approval order at the site. You must also notify BBMP at key construction stages: foundation completion, plinth level, and each floor slab. BBMP may conduct random inspections during construction. After construction completion, apply for a Completion Certificate (CC) and then Occupancy Certificate (OC) — both required before the building can be occupied.
