Why Building Plan Verification Matters

An approved building plan is the blueprint that the local authority has sanctioned for construction. Any deviation from this plan is technically illegal and can result in penalties, demolition orders, or denial of occupancy certificate.

What Is a Building Plan Approval?

The local municipal authority (BMC, BBMP, GHMC, PMC, etc.) approves:

  • Number of floors
  • Total built-up area and FSI/FAR utilisation
  • Setbacks (distance from property boundaries)
  • Common area allocation
  • Parking provisions
  • Staircase and lift placement
  • Fire safety provisions

How to Verify

Step 1: Obtain the Approved Plan

  • Request a copy from the builder/developer
  • The approved plan has: authority stamp, approval number, date, and officer signature
  • Compare with actual construction during site visit

Step 2: Verify with the Authority

AuthorityHow to Verify
Municipal CorporationVisit planning department with approval number
Development AuthorityOnline portal or office visit
Town Planning DepartmentWritten request with survey/property details

Step 3: Physical Verification

During site visit, compare:

  • Number of floors built vs approved
  • Setbacks maintained from boundary walls
  • Common areas exist as shown in approved plan
  • Parking spaces as per plan
  • Balcony/terrace areas match approved layout

Red Flags to Watch For

  1. Builder unwilling to share approved plan — deviation likely
  2. Building looks different from approved plan — verify specific differences
  3. Extra floors visible — most common and most risky deviation
  4. OC not obtained despite completion — plan deviation preventing OC
  5. Regularisation application pending — deviation acknowledged but not yet approved

Frequently Asked Questions

Can building plan deviations be regularised?

Some states allow regularisation of minor deviations by paying a penalty (compounding fee). Major deviations (extra floors, significant setback violations) may not be regularisable and can face demolition orders.

Who is responsible for plan deviations — builder or buyer?

The builder is primarily responsible for constructing as per approved plans. However, if you buy knowing about deviations, you share the risk. Always verify before purchase.
