What Is CMDA Approval?
The Chennai Metropolitan Development Authority (CMDA) is the planning authority for the Chennai Metropolitan Area. It issues planning permission — the sanction that your proposed development is allowed on that land under the master plan and development rules. Layouts and larger or special categories of buildings are the typical CMDA cases; exactly which category your project falls into depends on its size, height, use and location.
Our CMDA Services
- Building plan approval — planning permission for your proposed construction.
- Layout plan approval — approval for dividing land into plots.
- Completion certificate — certification after construction matches the sanctioned plan.
- Developer & professional registration — registrations required to operate with CMDA.
How a CMDA Application Moves
The path follows our standard approval process: we first confirm what the land-use zoning and development rules allow on your site, then assemble the documents and drawings, submit the application, and respond to CMDA's scrutiny queries until sanction. Fees and timelines depend on the project category and how complete the file is — a clean, complete file is the single biggest factor in a fast approval.
Where CMDA Applications Get Stuck
- Land-use zoning — the proposal doesn't match what the master plan permits on that land.
- Rule deviations — setbacks, floor space or height beyond what the rules allow.
- Title gaps — ownership and land records that don't line up.
- Slow query responses — scrutiny remarks that sit unanswered.
We check all of this before submission, so problems surface at the feasibility stage — not months into scrutiny.
CMDA or GCC — Which One Is Yours?
CMDA is the planning authority for the metropolitan area; the Greater Chennai Corporation issues building permits within city limits. Depending on your project, one or both may be involved. If you're not sure, that's exactly what our feasibility check answers.
