Verify Land Ownership and Title

Ensure that the property has a clear title with no encumbrances. Obtain the following documents:

Original land deed or property registration certificate

Tax payment receipts for the last 5 years

Mutation certificate from the revenue department

No Objection Certificate (NOC) from the local authority if applicable

This verification process typically takes 2-3 weeks and is essential before proceeding with design and approval submissions.

Frequently asked

You'll need land documents (title deed, property card, encumbrance certificate), proof of ownership verification, tax payment receipts for the last 5 years, a mutation certificate, and architectural drawings prepared by a CoA-registered architect. The specific requirements may vary slightly by state and municipality, so check with your local municipal authority for complete details.

Step 2: Architectural Design and Compliance

Engage a Licensed Architect

Hire an experienced architect registered with the Council of Architecture (CoA) who understands local building regulations. The architect will prepare:
