How to Get Building Plan Approval (State-by-State Guide)

Introduction

Before breaking ground on any construction, you need building plan approval from the local authority. The process, documents, and timelines vary by state. This guide gives an overview of how to get building plan approval in major Indian states.

Relevant tools: After approval, use our House Construction Cost Calculator and FAR/FSI tools for planning. For contractor billing, use RA Bill Generator.

Why Building Plan Approval Matters

• Legal: Unapproved construction can be penalised, sealed, or demolished
• Utilities: Water, sewage, and electricity often require approval proof
• Resale: Buyers and banks insist on approved plans and occupancy certificate
• RERA: In many states, developers must have approved plans before selling

Common Approval Authorities

Type	Authority
Municipal limits	Municipal Corporation / Council
Urban development areas	Development Authority (e.g., BDA, GHMC, MMRDA)
Industrial / special zones	State industrial corporation or special planning body

FAR / FSI and Bye-Laws

Each area has:

• FAR/FSI: Floor Area Ratio / Floor Space Index – max built-up area allowed
• Setbacks: Front, rear, side margins
• Height: Max height, number of floors
• Use: Residential, commercial, mixed – zoning rules apply

Use our FAR/FSI Calculator for area conversions. Check local bye-laws for exact limits.

After Approval: Occupancy and Completion

• Completion Certificate: Issued when construction is done as per plan
• Occupancy Certificate (OC): Allows occupation; required for utilities and resale

Do not occupy without OC where mandated. Maintain site registers and DPR for documentation.
