How do you use the builder trust score?
- Answer each of the six checks from what you have seen yourself: the RERA records, the builder’s past projects, and people who bought from them.
- Leave a check at “Not yet” until you have done it. Unchecked items score nothing, so the score rises only with real evidence.
- Read the score, the rating and the list of what is still open.
What do the six checks look at?
- RERA registration: the project you are buying into is registered on the RERA Karnataka website, with the same promoter and dates as your agreement.
- Delivery record: past projects were handed over by the dates the builder promised. Compare promised and actual dates for two or three projects.
- OC for past projects: finished projects received an occupancy certificate.
- Complaints and cases: look for complaints against the builder on the RERA website and for court cases about past projects.
- Visit to a past project: how the building, common areas and finishing have held up.
- Past buyers: what owners say about handover, defects and after-sales service.
How the score is worked out

Score
Weights of checks answered well ÷ 12 × 1002
Weights
Delivery 3; RERA, OC, complaints, visit 2 each; past buyers 13
Rating
Any problem or score below 50 = Weak; 80 and above = Strong; otherwise MixedA builder with one problem on record is rated Weak whatever the score, because a delivery or OC problem is the kind that costs buyers most.
Worked example: four checks done, all good
RERA, delivery record, OC and a site visit are good; complaints and past buyers are not checked yet. The score is 75 out of 100 (9 of 12) and the rating is Mixed. Checking complaints and speaking to buyers could take it to 100.
Worked example: all done, late deliveries
Every check is done and good except the delivery record: past projects were often handed over late. The score is 75 out of 100, but the rating is Weak because a problem was found.
What does this tool leave out?
- It does not look anything up for you; it scores what you have checked.
- The title and approvals of the flat you are buying. Use the property risk assessment.
- The builder’s finances, which buyers usually cannot see.
Frequently asked questions
Look up the builder’s projects on the RERA Karnataka website, compare promised and actual handover dates for a few past projects, confirm those projects got an occupancy certificate, search for complaints and court cases, visit a finished building and talk to people who live there.
Because the score should reflect evidence you have, not assumptions. If unchecked items scored as average, a builder you know nothing about could look fine. Leave a check at Not yet and the score rises as you complete it, one piece of evidence at a time.
Late handovers, a missing occupancy certificate or a pattern of complaints are the problems that cost buyers most, and a high score elsewhere does not cancel them. The tool flags the rating as Weak so you look into the problem before booking.
RERA Karnataka publishes complaints and orders against registered projects and promoters. Court cases may show up in searches of court records. Ask a property lawyer to help read them. Please consult a property lawyer before acting on what you find.
Not always. Size can mean more money and staff, but delivery and quality vary from project to project. Score the builder on the projects closest to yours in location, size and timing, and then check the specific project you are buying into.
A high score means the builder passed the checks you did. You still need to check the title and approvals of the flat you are buying, your budget and the agreement terms. Have a property lawyer review the agreement before you pay.
