Methodology

Every number on this site is computed from public registration records published by the Tamil Nadu Real Estate Regulatory Authority (TNRERA). We do not publish opinions dressed as data; where we score or interpret, the inputs and logic are disclosed on this page.

What are the data sources?

TNRERA's public register of projects (2017 to present), covering building and layout registrations: registration numbers, promoters, project descriptions, committed completion dates, and subsequent changes. Data is refreshed monthly; each page shows its last update date.

What is the Growth Signal Score?

A 0–10 locality score built from four components: registration momentum (new registrations in the last four quarters versus the prior four), entrant quality (the share of registrations from major multi-project and tier-1 developers), committed supply (units registered recently versus the locality's own history, discounted when supply runs far ahead of it), and project-mix shift (movement from plotted layouts toward built projects, a maturity signal).

Regularised layouts — amnesty-scheme legalisations of older unapproved layouts — are recorded but excluded from growth signals, because they reflect policy waves rather than developer conviction.

What the data can and cannot tell you

Registration data reveals what developers commit to and when — it does not measure construction quality, actual sales, or prices. Committed completion dates are legally binding under RERA; extensions to them are recorded and shown. Treat scores as one research input, not investment advice.

Who runs this?

VerifyRERA is operated by Newgen Digital, a Chennai/Kochi-based real estate marketing and intelligence practice. We help buyers verify projects, benchmark prices, and negotiate — that service is how this free data resource is funded.

The Health Check score

The Health Check compresses a project's public record into a 2–98 score and an A–E grade. It is arithmetic, not opinion: every input is a field parsed from a government filing, and the report lists each contribution next to its source.

What moves the score. Registration standing against today's calendar (active, past committed date, completed, cancelled) carries the most weight. The promoter's wider record — completions, past-due projects, and extension frequency across every project we track for that entity — carries the next. Approval verification (whether the planning-permission reference in the approval document matches the RERA declaration), single-project-entity flags, and documentation depth make smaller adjustments.

What the score is not. It is not a construction-quality audit, a legal title opinion, or a prediction. A high score means the public record is clean and consistent; a low score means the record contains patterns that deserve questions before money moves. Two projects with the same score can carry different flags — read the rows, not just the grade.

Stability. Scores recompute on every data sync, so a project's grade can change when the government record changes — an extension filing, a completion, a cancellation. That is by design: the score follows the register, not the brochure.
