Why the Completion Date Matters
Delay compensation under Section 18 of RERA is calculated from the date of possession disclosed at registration to the date the developer is actually able to offer possession, and that end date, in turn, is generally tied to when the project receives its occupancy certificate (or completion certificate, where an occupancy certificate is not separately required under the applicable state building regulations) from the competent municipal authority. Getting this date right matters directly to the amount of compensation an allottee can claim.
Why 'Substantial Completion' Isn't the Same Thing
Developers sometimes point to an internal engineer's certification of substantial completion of civil works, issued before the formal occupancy certificate, and argue the project should be treated as complete from that earlier date. Courts have rejected this, holding that only the actual grant of the occupancy certificate by the statutory authority (a verifiable, third-party milestone) can mark the completion date for RERA purposes; a developer's self-certification of progress does not substitute for it.
What If the Municipal Authority Delays the Occupancy Certificate?
A developer who has applied for an occupancy certificate but faces delay in the municipal authority's processing does not get to treat the application date itself as a substitute completion date. The developer's remedy in that situation is to pursue the municipal authority directly for release of the certificate; the allottee's compensation clock, in the meantime, generally keeps running.
What This Means for Your Complaint
If you are computing delay compensation, or reviewing a developer's own computation, the single most important document to obtain is the occupancy certificate itself, along with its actual issue date: not any developer-issued completion letter or offer-of-possession letter that predates it.
Frequently Asked Questions
What is an occupancy certificate?
It is the formal certificate issued by the competent municipal or development authority confirming that a building has been constructed in accordance with the sanctioned plan and is fit for occupation.
Can a developer claim the project was 'deemed complete' before the occupancy certificate was issued?
Courts have rejected this where the claim rests only on the developer's own internal certification of substantial completion: the occupancy certificate's actual issue date is the relevant benchmark.
What if the occupancy certificate application itself is delayed by the municipal authority?
The developer's remedy is to pursue the municipal authority directly; the delay-compensation period to the allottee is not shortened merely because an application was filed earlier.
