Revised Procedure for Plot Extent, Plot Boundary and CMWSSB NOC
The Chennai Metropolitan Development Authority, Administration Division, issued an order dated 12 May 2016, with no order number shown in the supplied text, revising how site extent and boundaries are determined during planning permission scrutiny. It also allows planning permission involving a Sewerage Treatment Plant to be released before the CMWSSB no objection certificate is produced, subject to an undertaking and later compliance, and took immediate effect.
What the procedure governs
The Chennai Metropolitan Development Authority, Administration Division order dated 12 May 2016 governs the measurement of plot extent for FSI and plot coverage scrutiny, the boundary used for setbacks, and the timing of the CMWSSB no objection certificate for a Sewerage Treatment Plant. The supplied text does not show an order number.
The procedure affects planning permission applicants, developers, architects, licensed surveyors and Chennai Metropolitan Development Authority planning officers. It is particularly relevant where site measurements differ from the FMB, PLR, patta or registered ownership document, or where a development requires its own sewage treatment arrangements.
Site extent and boundary measurement
The revised scrutiny procedure addresses errors that may arise when large, irregular or many-sided plots are measured and superimposed on FMB or PLR measurements.
Key provisions are:
- Where the difference between the linear measurements on site and in the FMB is less than 1 per cent, superimposition is not required.
- In those cases, the lowest extent shown by the patta, registered document or site condition is used.
- A Deputy Planner decides cases where the difference is less than 1 per cent.
- Where the linear measurement difference is more than 1 per cent, the case and superimposed plan must be placed before the Committee of Senior Officers for a decision.
- For setback measurement, the inner boundary certified by the architect or licensed surveyor must be used.
- Encroachments, and land over which the applicant or developer has no right, are excluded when applying the relevant development controls.
Sewerage Treatment Plant clearance
The Chennai Metropolitan Development Authority procedure applies where no sewerage system is available from Metro Water or the local body, and a proposal exceeds 50 dwelling units or 2,500 square metres of commercial area. A Sewerage Treatment Plant must be provided and maintained within the site, with clearance from CMWSSB or the Pollution Control Board, as applicable, for its location and design.
Planning permission may be released before the CMWSSB no objection certificate is submitted if the applicant undertakes to:
- obtain clearance for the Sewerage Treatment Plant location and design before starting construction;
- construct it according to that clearance without violating Development Regulation requirements; and
- produce the CMWSSB no objection certificate at the Completion Certificate stage.
Construction of the Sewerage Treatment Plant according to the approved plan is checked during the Completion Certificate stage.

Common questions
Which plot extent will CMDA use for FSI when the records and site measurement differ?
If the difference between the site and FMB linear measurements is less than 1 per cent, the lowest extent among the patta, registered document and site condition is used without superimposition.
What happens when the site measurement differs from the FMB by more than 1 per cent?
The case must be placed before the Committee of Senior Officers with a superimposed plan for a decision.
Which boundary is used to calculate setbacks?
The inner boundary certified by the architect or licensed surveyor is used for setback measurement.
Can planning permission be issued before obtaining the CMWSSB NOC for an STP?
Yes. The applicant must undertake to obtain clearance for the Sewerage Treatment Plant location and design before construction, comply with Development Regulation requirements, and submit the no objection certificate at the Completion Certificate stage.
