BBMP building plan approval checklist (2026)
What you need to get a building plan sanctioned in Bangalore: the documents, the steps, the charges to budget, and common mistakes to avoid.
Before construction begins in Bangalore, most residential buildings need a sanctioned building plan from the local authority (BBMP within city limits). This guide explains the process, the documents you need and what to budget for. It is general guidance, not legal advice; confirm current rules with a licensed architect or the authority.
In short: engage a licensed architect or engineer, prepare drawings that follow the zoning, floor area ratio and setback rules for your plot, submit them with your ownership and tax documents, pay the scrutiny and betterment charges, and receive the sanctioned plan before you start building.
Who needs plan approval?
Almost every new residential building and major reconstruction needs sanction. Building without an approved plan risks penalties, demolition of unauthorised portions, and problems getting water, power, an occupancy certificate or a home loan.
Documents commonly required
- Title deed and sale deed of the property
- Khata certificate and Khata extract
- Latest property tax paid receipts
- Encumbrance certificate
- Survey sketch or tippani and property drawings
- Building drawings prepared by a licensed architect or engineer
- Identity and address proof of the owner
The approval process, step by step
- Engage a licensed architect or structural engineer
- Prepare drawings that follow zoning, floor area ratio and setback rules
- Submit the application with documents, online where available
- Departmental scrutiny of the drawings and documents
- Pay the scrutiny fee, betterment charges and applicable cess
- Receive the sanctioned plan and commencement approval
- After construction, apply for the occupancy certificate
Charges to budget for
Expect scrutiny fees, betterment charges, labour welfare cess (commonly around one percent of estimated cost) and consultant fees. Exact amounts depend on your plot, built-up area and zone, so treat these as items to budget rather than fixed figures. Confirm current rates with your architect or the authority.
Common mistakes to avoid
- Starting work before the plan is sanctioned
- Ignoring setback and floor-area-ratio limits, which creates unauthorised portions
- Missing or outdated Khata and tax documents
- Not keeping the sanctioned plan and approvals on record
Frequently asked questions
Do I need BBMP approval for a 30×40 house?
Yes. New residential construction needs a sanctioned plan regardless of plot size. Requirements and charges scale with built-up area and zone.
How long does plan approval take?
It varies with the authority, the completeness of your documents and the zone, commonly a few weeks to a couple of months. A licensed architect who knows the local process helps avoid delays.
What happens if I build without sanction?
Unauthorised construction can attract penalties, demolition of the unauthorised portion, and difficulty getting utilities, an occupancy certificate or a loan. Get the plan sanctioned first.
