Got Questions?

Frequently Asked Questions

Clear, transparent answers regarding costs, approvals, timelines, and guarantees.

For residential buildings up to Stilt+3 floors, approval through the online Single Window Portal typically takes 25 to 45 business days once all documents are verified.

You need registered sale deed, parent documents, latest Patta / Chitta, EC (Encumbrance Certificate), FMB sketch, property tax receipt, and architectural working blueprints.

Under the Tamil Nadu Combined Development Regulations, the base FSI for residential plots generally ranges from 1.5 to 2.0 depending on road width and plot frontage.

New construction now mandates DTCP / CMDA approval. We assist landowners in obtaining DTCP regularization (Form II) before submitting the building plan.

Initial feasibility review of your plot documents and zoning regulations is provided completely free of charge.
