The portal also provides application manuals, document checklists, NOC guidance, approved-plan information and details of registered professionals.

Planning permission and building licence are different

Planning permission confirms that a proposed development complies with the Tamil Nadu Town and Country Planning Act, applicable land-use plans and building rules.

A building licence is issued by the concerned local body. Depending on the proposal, an applicant may need both approvals before starting construction.

What services are available?

The portal handles applications connected with:

• Layout and subdivision approval
• Building-plan approval
• Land-use reclassification
• Commencement notification
• Plinth-level inspection
• Last-storey inspection
• Completion certificate

It also routes applications to the appropriate planning authority or local body.

How does the approval process work?

The applicant and registered professional submit the property details, application and digital drawings online.

After the scrutiny fee is paid, the application is routed to the concerned authority. Officials examine the land ownership, approved land use, road access, building rules and required NOCs. A site inspection may also be conducted.

If the proposal complies with the rules and the applicable charges are paid, planning permission and the local-body building licence are issued through the relevant process.

What documents are normally required?

The exact documents depend on the property’s location and the type of development. Common requirements include:

• Sale deed, lease deed or other ownership document
• Patta or TSLR
• FMB sketch
• Encumbrance Certificate
• Survey number and subdivision details
• Site plan and key plan
• Floor plans, elevations and sections
• Road-width sketch
• Applicable NOCs

Adangal, earlier parent documents, legal opinion and additional departmental clearances may be required in certain cases.

Is self-certification available?

The portal provides a self-certification route for eligible small buildings.

The official manual currently describes this facility for Ground or Ground+1 buildings not exceeding seven metres in height, with a built-up area of up to 3,500 sq.ft on a plot of up to 2,500 sq.ft. 

Tamil Nadu has announced plans to extend the self-certification scheme to eligible residential buildings with a built-up area of up to 5,000 sq.ft, covering G+2 or Stilt+3 structures, subject to formal implementation and applicable conditions.

If the property requires an NOC or exceeds these limits, the applicant must follow the normal building-plan approval process.

How long is planning permission valid?

The current DTCP Page states that planning permission is valid for eight years from the date of issue.

Who approves the application?

The approving authority depends on the location, building size, height, use and proposal category.

• CMDA handles planning matters within the Chennai Metropolitan Area.
• DTCP and its subordinate offices handle areas outside CMDA.
• Local bodies can approve eligible proposals under powers delegated to them.

The portal’s Know Your Local Body facility can help applicants identify the correct office.

What should property buyers verify?

A local-body or Village Panchayat approval alone should not be mistaken for DTCP layout approval.

Before purchasing a plot, buyers should verify:

• Planning authority approval number
• Approved layout drawing
• Survey number and subdivision
• Land classification
• Approved land use
• Planning jurisdiction
• Road access and road width

Construction on an unapproved plot or construction that deviates from the sanctioned plan may be treated as unauthorised and can face enforcement action.

The Online Planning Permission Portal is therefore a useful official source. However, its FAQ should be treated as a starting point—not as the only legal authority for making a property decision.

Disclaimer: Planning requirements vary according to the property’s location, land classification, proposed development and subsequent amendments. Owners should verify the latest rules and consult a registered professional or competent authority before purchasing land or starting construction.

The Tamil Nadu government has instructed Corporation and Municipality Commissioners to reduce delays in planning permission and building approval processing. The direction was issued by Director of Municipal Administration P Madhusudhan Reddy

This move is important for landowners, builders, developers, and property buyers because approval delays often affect construction timelines, project launches, loans, and sale agreements.

New Timelines for Approval

As per the latest direction:

➡️Site inspections must be completed within 5 working days after receiving the online application.

➡️The inspection report should be uploaded within 2 days after inspection.

➡️Planning permission should be issued within 24 days.

➡️Building permits should be issued within 7 days from the date of application submission.

This gives applicants a clearer idea of how long the approval process should take.

Less Manual Follow-Up, More Online Processing

The government has also made it clear that applicants, architects, engineers, and third parties should not be forced to appear in person unnecessarily.

All payments must be made through the online payment module. Officials have also been warned that manual interference, delay, or lack of transparency in online approvals may lead to action.

This can help reduce confusion and repeated visits to local offices.

When Fresh Field Inspection May Not Be Needed

One important clarification is that if ownership documents have already been verified by CMDA or DTCP, a fresh field inspection may not be necessary.

However, this does not mean applicants can submit incomplete or false details. The order clearly states that if information submitted to CMDA or DTCP is later found to be false, authorities can stop construction at any stage.

So, faster approval does not remove the need for proper document verification. It only makes the process quicker when the submitted records are correct.

If the application contains false information or if the land has legal or planning issues, construction can still be stopped later.

Why Land Verification Matters Before Applying

A clean application has a better chance of moving faster. Problems usually arise when there is a mismatch in survey number, unclear ownership, missing approval, wrong land use, insufficient road access, or restrictions such as road widening, reserved land, or flood risk.

Property owners should not assume that the new timeline guarantees approval. The land and documents must still be legally clear.

So, before spending money on drawings, fees, and construction planning, the property should be checked properly.

Verified.RealEstate helps buyers, landowners, and developers check whether a property is suitable for development before applying for approvals.

Through tools and services such as LandLens, checks can include title review, encumbrance, Patta, survey number, zoning, road width, approval status, flood indicators, and surrounding land-use risks.

This helps applicants identify issues early instead of discovering them after submitting the application or starting construction.

Conclusion

Tamil Nadu’s fixed timelines for planning permission and building permits are a welcome step for faster and more transparent approvals.

But speed is useful only when the land records are clear. Property owners and builders should verify the land, approval status, and development rules before applying, so that the process does not get delayed or challenged later.
