Check approvals on any survey number
Type a survey number and its village, and get every layout approval, building plan permit, completion certificate and RERA registration recorded on it, from CMDA, DTCP, the panchayats and RERA. Each record says whether it names your exact sub-division, another part of the same survey, or a neighbour.
Sign in with your phone to run it. You see the price and approve it before anything runs.
- The reverse of the portals: survey number in, every approval ever recorded on it out
- Exact, parent and adjacent matches told apart, so a permit on a sibling sub-division is not mistaken for yours
- What was searched and the years each register spans, so an empty answer is honest about its coverage

One thing at a time. Fill it in and press Run.
The answer
From the register, with its date and source.
Nothing run yet. The answer appears here with everything this mini adds:
- The reverse of the portals: survey number in, every approval ever recorded on it out
- Exact, parent and adjacent matches told apart, so a permit on a sibling sub-division is not mistaken for yours
- What was searched and the years each register spans, so an empty answer is honest about its coverage
Approvals by survey number, briefly
A reverse approval lookup starts from the land and ends at the approval: you give the survey number, and it returns the permits and registrations recorded against it, instead of needing the permit number first.

CMDA, DTCP, the Greater Chennai Corporation, village panchayats, town panchayats and the Tamil Nadu RERA, searched together in one run.
- Match types
- Exact, parent, adjacent
Exact names your survey as written. Parent names another sub-division of it. Adjacent names a neighbouring survey, a lead and not your permission.
- Why the village matters
- Numbers repeat
Survey numbers restart in every revenue village, so the same number exists in many places. Give the village and the answer is yours.
How to check approvals on a survey number
- 1
Type the survey number
One or several, separated by commas, for example 506/1D2 or 444, 445.
- 2
Add the village, taluk or district
Strongly recommended. Without a place the search is statewide and bare numbers match everywhere.
- 3
Press Run and read each record
Records are grouped by place, each with its authority, kind, number, date and how it matched your survey.
Layout approval, building permit, completion certificate and RERA registration
Four kinds of record the answer can show, and what each one does and does not tell you.
| Layout approval | Building permit | Completion certificate | RERA registration | |
|---|---|---|---|---|
| Issued by | CMDA or DTCP | The local body or planning authority | The planning authority or local body | The Tamil Nadu RERA |
| Says | The land may be divided into plots and roads as drawn | A building may be put up as drawn | The building was inspected after it was built | The promoter registered the project with the regulator |
| Is a planning approval | Yes | Yes | Yes, and the strongest of the three | No, it is a registration |
When it helps with land
A seller says it is approved
Check the survey number before you ask for the paperwork, then match the approval number on the letter against the record.
Buying in a layout
A layout often spans several survey numbers. Search them all at once and see which approval covers which.
Due diligence on a project
Building permits, completion certificates and RERA registrations for the same land, side by side.
A record here is a lead, not a clearance: it does not prove the approval is valid, covers your exact sub-division, or that the seller owns the land. Take the approval number to the issuing office, and check title in the revenue records and the EC.
Questions people ask
Can I check planning approval using only a survey number?
Yes. The government portals ask for the approval number and return the land. This does it the other way round: type the survey number and the village, and it returns every record in the registers we hold that names that survey.
Does an empty result mean the plot has no approval?
No. It means nothing in the registers we hold names that survey. The approval may be older than a register's coverage, from a body we do not read, or written without a survey number. The answer lists what was searched and the years each register covers.
What does a parent match mean?
The approval names the parent survey or another sub-division of it. Your plot may sit inside that layout, or the permit may belong to a sibling plot; read the approved plan to see which sub-divisions it lists.
Why does my survey number return nothing when the seller says the layout is approved?
Your plot may be a later sub-division that the approval never names, the approval may predate our coverage for that authority, or its paperwork may carry no survey number. Ask for the approval number and try the street or approval number search as well.
Does a RERA registration mean the layout is approved?
No. A RERA registration means the promoter registered the project with the regulator. The planning approval comes from CMDA, DTCP or the local body. The answer labels each kind separately.
Can I check several survey numbers at once?
Yes. Separate them with commas, for example 84/1A2, 84/4, 99/1. Each result shows which of your numbers it matched.
Can I open the approval document?
Where the register carries the letter or the plan, the record links to it.
When is it charged?
Only when a record comes back. Nothing found is not charged.
