Chennai Metropolitan Area plan sheets · free

CMDA Master Plan and DDP Map Sheet API

Yes. The LandLens planning map API takes a place name in the Chennai Metropolitan Area, a ward, neighbourhood, village, municipality or town panchayat, and returns the CMDA master plan or detailed development plan sheets that cover it, each with the local body, the plan type, a viewer link and the PDF itself. 421 sheets are indexed across the Chennai Corporation, the municipalities, the panchayat unions and the town panchayats. It costs nothing. It returns the plan document; the land use zone at one plot is the separate zone_check call.

Where the data comes from

Register

The land use plan sheets of the Chennai Metropolitan Development Authority: the master plan sheets and the detailed development plans, published village by village and ward by ward.

Coverage

421 sheets: 184 for the Chennai Corporation, 35 for the municipalities, 180 for the panchayat unions and 22 for the town panchayats. The Chennai Metropolitan Area only.

How current

The sheets are the plans as CMDA published them, held on our own file host. They change only when CMDA issues a new plan.

How we read it

The place is matched against the sheet names, the local body and the file name: as a whole word first, then from the start of a word, and only then anywhere inside a name. If the whole phrase misses, its longest meaningful word is tried and the answer says so.

Who uses it

Buyers and architects

Open the land use plan for the village or ward a plot is in, before designing or buying.

Chat and support bots

Answer "where is the master plan for my area" with the actual sheet, not a link to a search page.

Property sites

Link each Chennai locality page to its CMDA plan sheet.

Limits and good practice

  • The Chennai Metropolitan Area only. Outside it the plan is a DTCP master plan, which this index does not hold.
  • Sheets are named after the revenue village or ward. A colony or layout name will not match; use the village or neighbourhood.
  • A sheet shows the zoning of a whole village or ward. For the zone at one plot, call zone_check with cmda_landuse or master_plan.
  • A few sheets have no direct PDF link; detail_url then opens the local body's listing page.

Pricing

Free

The planning map costs nothing. Free calls have their own allowance per hour and per day, counted across every key and connected app on the account. Credits come from the same LandLens wallet as the chat and the minis. How billing works.

Calling at volume?

Free calls have an hourly and daily allowance. For more than that, or a platform built on these registers, we set up limits and a plan to match.

Questions

Is there an API for the CMDA master plan map?

Yes. Send a place name and the API returns the CMDA master plan or DDP sheets that cover it, with the PDF link. It is free.

How do I find the land use zone of my plot?

Use zone_check with the plot's latitude and longitude and the cmda_landuse or master_plan check. This call returns the plan sheet, not the zone at a point.

Does it cover DTCP master plans outside Chennai?

No. Only CMDA's plans for the Chennai Metropolitan Area are indexed. zone_check reads the master plan zone at a point in several other planning areas.

What is a DDP?

A detailed development plan: CMDA's larger scale land use plan for a smaller area, read together with the master plan.
