A construction-defect claim should distinguish cosmetic snagging, deviation from specification, structural defect, water or service failure, sanctioned-plan deviation and common-area deficiency. Evidence must show the defect, responsibility, notice and reasonable rectification cost. Dated photographs help, but an independent engineer or technical inspection can be decisive for contested defects.
Proving defects
Document defects with photographs, expert reports and correspondence. Builder non-compliance with sanctioned plans strengthens the complaint.
Legal framework and key principles
The applicable section, forum and evidentiary record must be checked together. These are the main points to organise before a specific opinion is formed.
RERA imposes promoter obligations and includes a statutory defect-liability framework for specified structural or workmanship/service defects.
Consumer law may address deficiency in service and compensation where jurisdiction is established.
The agreement, sanctioned plan and promised specification define important benchmarks.
Practical steps
- Create a room-wise and system-wise defect list
- Photograph and video defects with dates
- Obtain an independent technical assessment for serious issues
- Notify the promoter and allow documented inspection
- Compare agreement, plan and delivered work
- Seek rectification, cost, interest or other appropriate relief
Documents to collect
Start with readable copies and a short index. Preserve originals, digital metadata and proof of service where relevant.
What usually affects the decision
Forum and local context
Section 31 of RERA permits an aggrieved person to complain about statutory violations. Section 18 addresses refund, interest and delay consequences in specified circumstances. Consumer remedies may remain relevant for deficiency in service, while some disputes require a different forum or additional relief.

Frequently asked questions
What is the best evidence of defective construction?
Use dated visual records, the agreement and specification, sanctioned material where relevant, correspondence and an independent engineer’s report for technical defects. The evidence should identify location, cause, seriousness and recommended rectification.
Must the builder be given a chance to repair?
Documented notice and access can show fairness and clarify whether the promoter accepts responsibility. Urgent safety repairs may require immediate action, but preserve evidence and obtain technical advice first where possible.
Can common-area defects be complained about?
Yes where statutory and contractual obligations apply, but authorisation and collective evidence may be important. The association or affected allottees should document the common area, project obligation and requested rectification.
How do I prove defective construction?
Use dated photographs, an engineer’s report, the sanctioned plan and correspondence with the builder to establish defects and non-compliance.
