Chennai Metropolitan Area Third Master Plan faces delay
The Third Master Plan for the Chennai Metropolitan Area is delayed. The reporting so far gives no reason, revised schedule or procedural status.
source · Deccan Chronicle
Background
The Chennai Metropolitan Development Authority (CMDA) prepares a statutory master plan for the Chennai Metropolitan Area under the Tamil Nadu Town and Country Planning Act, 1971. A master plan sets land use, zoning and development regulations. It tells owners and builders what can be built where.
The Second Master Plan was approved in 2008 and had a 2026 horizon. The Third Master Plan is its successor. It is meant to cover the expanded metropolitan area.
Where it stands
The plan has not been released. The record shows the following:
- 11 August 2026: reports said the Third Master Plan faces delay. No reason, revised schedule or procedural status was given.
- 11 August 2026: a further report said the Master Plan faces fresh delay linked to growth rules. This one is unverified. It also gave no revised timeline or formal step.
- 8 October 2026: reports said Arakkonam is set to join the Chennai Metropolitan Area as the CMDA expands its planning boundary.
- 8 October 2026: an unverified report said the Chennai Metropolitan Area is set to cover 5,904 square kilometres.
- 28 October 2026: a report said the plan is now likely to be released in 2027. No formal stage, such as a draft for objections or a notification, is reported.
Because no formal stage is on record, the status of the plan is unclear. It is not yet reported as a draft, a consultation or a notified plan.
Who is affected
- Buyers of plots and flats: the zoning that applies to a parcel may change once a new plan is notified. The current rules are not yet replaced.
- Owners of land in newly added areas: if Arakkonam and other areas join the metropolitan area, they would come under metropolitan planning. The boundary expansion is reported as "set to" happen. A final notification is not yet reported.
- Builders and developers: project planning may depend on land use and development rules in the new plan. Those rules are not yet public.
- Lawyers and advisers: due diligence on zoning will need to track which plan applies on the date of approval or purchase.
What to check before you buy or build
- Ask which master plan the parcel falls under today. Do not assume the Third Master Plan applies.
- Check the current land use classification of the parcel in the plan that is in force.
- Find out whether the parcel lies in an area reported as joining the metropolitan area, such as Arakkonam. Confirm whether any boundary notification has been issued. It is not yet reported.
- Do not rely on press reports of the 5,904 square kilometre figure. It is unverified.
- Ask the seller and the planning authority in writing about any pending zoning change.
- Keep dated copies of the zoning confirmation you receive.
- For large purchases, have a lawyer re-check the position close to registration, since the plan could move to a formal stage at short notice.
What happens next
The latest report expects release in 2027. The timeline does not say what form that release will take. The steps that would normally matter to owners are a draft for objections and a final notification. None is reported yet. Watch for an official announcement from the CMDA, a call for public objections, and any notification of the expanded boundary.

Questions people ask
Has the CMDA Third Master Plan been released?
No. As of 29 October 2026 it has not been released. A report dated 28 October 2026 says it is likely in 2027. No draft for objections or notification has been reported, so no formal stage has been reached.
When will the Chennai Third Master Plan come out?
A report dated 28 October 2026 says it is likely to be released in 2027. No exact date is reported. Earlier reports on 11 August 2026 described delays without giving a revised schedule, so the 2027 timing is an expectation, not an official date.
Which master plan applies to my land in Chennai now?
The Third Master Plan has no reported formal stage, so it does not yet apply. The Second Master Plan, approved in 2008 with a 2026 horizon, is the document on record. Confirm the position for your parcel in writing with the planning authority.
Is Arakkonam part of the Chennai Metropolitan Area?
Reports of 8 October 2026 say Arakkonam is set to join as the CMDA expands its planning boundary. A final notification is not yet reported. Check whether a boundary notification has been issued before assuming metropolitan rules apply to land there.
How big will the Chennai Metropolitan Area be?
An unverified report of 8 October 2026 says the area is set to cover 5,904 square kilometres. This has not been confirmed by an official notification in the record. Treat the figure with caution until the CMDA publishes it.

Official entries come from government, court or authority publications. Reported entries come from established press and are not official confirmation. Unverified entries come from a single source we do not vet, published so you can see what is being said and judge it yourself. Verified.RealEstate writes the summaries; the linked document is authoritative.
How this tracker works
This tracker is re-checked every morning. "Checked" is the date the sources were last read; "changed" is the date the status last moved. An entry that moves the status carries a badge showing the stage it moved to.
Every sourced entry appears on the timeline, badged and named to where it came from: Official for a government, court or authority publication, Reported for established press, Unverified for anything else. Publishing an entry is not a claim that it is true, it is a record of what was said and by whom.
The status is held to a higher bar than the timeline. Only an official publication can move it on its own. A status change reported by the press waits for a second outlet or for review, and one from an unverified source always waits for a person.
