CRZ, flood, forest and 37 more zone checks at any plot
Drop a pin and tick the layers that worry you: coastal regulation, flood, water bodies, reserve forest, airport height, power lines, monuments, temple and waqf registers and more. Each layer comes back clear, flagged or not covered, with the zone name or the distance behind it.
Sign in with your phone to run it. You see the price and approve it before anything runs.
- A verdict per layer with the distance or the zone name behind it, not a bare yes or no
- Honest coverage: a layer that does not map your district says so instead of showing clear
- Severe layers you did not tick are swept too, and flagged if they hit

From the register, with its date and source.
Nothing run yet. The answer appears here with everything this mini adds:

Zone checks, briefly
The Coastal Regulation Zone is the strip of coast and tidal water where building is restricted under the CRZ Notification, 2019, graded from CRZ-I (ecologically sensitive) to CRZ-IV (the water itself).
- Layers
- 40
Coastal, flood, wetland, forest, airport, power line, rail and metro, heritage, endowment registers, planning land use and more. Tick only the ones you need.
- Verdicts
- Clear, flagged, not covered
Not covered means the layer holds no data for that district. It is never shown as clear.
- Swept anyway
- 7 severe layers
Monument buffers, reserve forest, Ramsar wetlands, swamps, flood, water bodies and the Redhills catchment are read even when you did not tick them, and shown if they hit.
How to check the CRZ zone of a plot online
- 1
Place the pin
Tap the plot on the map, paste a Google Maps link to it, or use your location while you stand there.
- 2
Tick the layers
Coastal regulation is ticked by default with flood, water body, forest, airport, power line, temple and waqf. Add or remove any. The button shows the price as you tick.
- 3
Read each verdict
Flagged layers name the zone or give the distance. Take those to the planning authority before a plan is drawn.
When it helps with land
Coastal plots
Near the sea, the CRZ category and the distance from the high tide line decide whether and how far back you can build.
Before an advance
A flood extent, a tank bed or a forest boundary under the plot is cheaper to find now than after the sale deed.
Tall buildings
Near an airport or under a power corridor, the height and setback limits shape what the plot is worth.
A clear layer means that map holds nothing at that point, not that you may build. Approval still rests with the planning authority, the building rules and a site inspection, and ownership is in the revenue records.
Questions people ask
How do I check whether my land is in a CRZ zone?
Drop a pin on the land above, keep Coastal regulation ticked and press Run. The answer says whether the point falls in a coastal regulation zone, and which category, or, when it does not, how far away the nearest mapped coastal zone is.
How far from the sea can I build?
Under the CRZ Notification, 2019 the no development zone is 50 m from the high tide line in CRZ-IIIA (densely populated rural areas) and 200 m in CRZ-IIIB. In CRZ-II (developed urban areas) building follows the existing roads and structures, and CRZ-I areas are largely closed to new construction. The coastal zone management plan and the planning authority have the final word.
Is a clear result a guarantee I can build?
No. It means that layer holds nothing at that point. Approvals still depend on the planning authority, the building rules and a site inspection.
What does not covered mean?
Some layers exist only for certain districts, the aquifer and Redhills catchment layers for Chennai and Tiruvallur for instance. Outside them the layer has no data, and the answer says so rather than showing clear.
Which layers can I check?
Forty in all, among them coastal regulation, flood, water body distance, Ramsar wetlands, eco-sensitive zones, reserve forest, airport height limits, power corridors, railway and metro distance, monument buffers, burial grounds, quarries, mapped slum areas, the temple, waqf and Bhoodan registers, gazette acquisition notices and planning land use.
How is a run priced?
By the number of layers you tick, in steps of seven, with a cap for all of them. The button shows the price as you tick, and nothing is charged unless at least one layer returns a real verdict.
How current are the layers?
Each layer is refreshed on its own cadence from the state GIS and the registers. The verdict carries the layer's own zone names and distances.
