KMC Building Plan Approval in Kolkata (2026) — Complete Step-by-Step Guide

If you are planning to build a house in Kolkata, getting approval from the Kolkata Municipal Corporation (KMC) is mandatory. Without it, your construction can be stopped, you may face legal penalties, and you may not get utilities like water and electricity.

What is KMC Building Plan Approval?

KMC approval is the official permission required before starting any construction. It ensures your building complies with zoning laws, building height restrictions, safety norms, and FAR (Floor Area Ratio) regulations.

Step-by-Step Process

Step 1: Hire a Licensed Architect

You cannot submit plans directly to KMC — a licensed, KMC-empanelled architect is mandatory. They prepare and certify all drawings.

Step 2: Prepare Building Plan

Your architect will prepare complete drawings including floor plans, elevation, structural design, and drainage layout.

Step 3: Submit Application to KMC

The application is submitted online through KMC’s e-services portal along with all required documents. Your architect typically manages this submission.

Step 4: Pay Approval Fees

Fees depend on plot size, building area, and location. Typical range: ₹50,000 – ₹2,00,000+

Step 5: Plan Scrutiny & Approval

KMC engineers review the plan, may conduct a site visit, and may suggest modifications before granting approval.

Step 6: Receive Sanction Plan

Once approved, you receive the official sanctioned plan. Only after this can construction legally begin.
