These are sums of what the builder has put on the public record across their projects — a sense of how big a builder this is, not build quality and not whether they finish on time.

Government Guidance Rate

Maharashtra IGR — Annual Statement of Rates

In Maharashtra it’s called the ready reckoner rate.

₹1,55,712per sq yd
₹1,86,230per sq m
Which rate
residential flat (built)
Matched to
The rate published for “Malad”.
In force
2026-2027 schedule

What this number is — and isn’t

  • The minimum value Maharashtra’s registration department will register a sale at. Stamp duty is usually charged on this or the price in the sale deed, whichever is higher.
  • Not a market price. Sales normally register above it, and how far above varies by place and by project.
  • Its fit depends on the grain the state publishes at. This one is matched at the level of locality, and says so above. How Horizon decides what to show.

The occupancy certificate — the proof that isn’t here

An approved plan is the government’s approval to build. It is not proof the project was built to that plan. That sign-off is the Occupancy Certificate (OC) — issued by the planning authority, the same body that approved the plan, not by RERA— and it isn’t in this record. Ask the builder for it, or check with the authority. Without an OC, banks may decline home loans, and any deviation from the approved plan carries penalty or demolition risk.

Volume and mix are context, not a verdict — a busier body isn’t a safer project. And this counts RERA-registered projects on Horizon’s record, not all construction.

What this record cannot tell you

  • Build quality — no filing records how well it was actually built.
  • Private disputes — only complaints escalated to the authority appear here.
  • What it will be worth — the record is the past; it does not price the future.
