Bangalore Development Authority to flats: After occupancy certificates, no approval for fresh plans

Bangalore Development Authority (BDA) circular dated July 15, 2026 curbs approval of revised building plans after occupancy certificates (OC) are issued.

Consent from at least two-thirds of apartment owners is required before any modification is approved where third-party rights have been created.

Revised sanctions are barred in projects where the permissible Floor Area Ratio (FAR) has already been exhausted.

The circular responds to a legal battle involving HM Tambourine apartments in south Bengaluru, where residents challenged a 2016 modified sanction plan approved without mandatory owner consent under Karnataka Ownership Flats Act (KOFA), 1972, and Real Estate (Regulation and Development) Act (RERA), 2016.

Resident welfare associations said the circular provides greater clarity and lasting protection to apartment owners across Karnataka.
