Building Approval Drawing Consultant: Planning to construct your dream home, commercial building, or renovate an existing structure? Before you start laying bricks, there’s a crucial step that can make or break your project—getting proper building approval drawings. This is where a building approval drawing consultant plays a vital role in ensuring your construction is legally compliant, structurally sound, and approved by government authorities like CMDA or DTCP.
In this article, we’ll walk you through everything you need to know about building approval drawings, why hiring a consultant is essential, how to choose the right one, and the cost involved.
What is a Building Approval Drawing?

A building approval drawing is a set of technical plans and designs submitted to the local development authority (CMDA, DTCP, Panchayat, Municipality, etc.) to get permission to begin construction. These drawings are essential for verifying that your structure complies with local building codes, zoning regulations, and safety standards.
Common Drawings Included:
- Site Plan – Shows boundaries, setbacks, and property orientation.
- Floor Plan – Layout of rooms, walls, doors, and circulation paths.
- Elevation – Front, side, and rear view of the building.
- Sectional View – Cross-sections to show structural elements.
- Structural Drawing – Load-bearing elements, columns, beams, and slab details.
- Drainage and Plumbing Plan – Layout for water flow and sewage.
