Building Plan Approval Online: Process & Documents

Before starting any construction in India — whether a house, apartment, or commercial building — you must obtain building plan approval from the local municipal corporation or development authority. Constructing without approval is illegal and can lead to demolition, fines, and inability to get utilities connected.

The Government of India has introduced the Online Building Permission System (OBPS) to simplify and digitize this process. This guide covers the complete process, documents needed, fees, timelines, and the OBPS portal.

What is Building Plan Approval?

Building plan approval (also called construction permission or building permit) is the official permission granted by the local body (municipal corporation, development authority, or panchayat) to construct or modify a building. The approval ensures:

• The building complies with local building bylaws and zoning regulations
• Proper setbacks, floor area ratio (FAR), and ground coverage norms are followed
• Fire safety, structural safety, and environmental norms are met
• The construction does not violate the master plan of the area

Who Needs Building Plan Approval?

• New construction — residential, commercial, or industrial
• Addition or alteration to an existing building
• Reconstruction after demolition
• Change of use (e.g., residential to commercial)
• Compound wall construction (in some municipalities)

Note: Small repairs and interior renovations may not require approval in some areas. Check with your local municipal body.

Documents Required

Land-Related Documents

• Property ownership proof — registered sale deed or allotment letter
• Mutation certificate — showing your name in revenue records (see mutation guide)
• Encumbrance certificate — from the sub-registrar office
• Land use certificate — confirming the land is designated for the proposed use
• NA order — if land was converted from agricultural use (see land conversion guide)
• Property tax receipts (latest)

Building Plan Documents

• Architectural drawings — site plan, floor plans, elevation, section drawings prepared by a licensed architect
• Structural drawings — for buildings above G+1 or as per local rules, prepared by a structural engineer
• Soil test report (for multi-storey buildings)
• NOC from fire department (for commercial/multi-storey buildings)
• NOC from airport authority (for buildings near airports — height restrictions)
• Environmental clearance (for large projects — via parivesh.nic.in)

Personal Documents

• ID proof — Aadhaar card, PAN card
• Passport-size photographs
• Architect's license copy and undertaking
• Structural engineer's license copy (if applicable)

Online Building Permission System (OBPS)

The OBPS portal (obps.gov.in) is the national platform for online building plan approval, launched under the Ease of Doing Business initiative by the Ministry of Housing and Urban Affairs.

How to Apply on OBPS

1. Visit obps.gov.in or your state/city's building permission portal
2. Register as a citizen/applicant
3. Select your municipal body (city/town)
4. Fill the application form with land and building details
5. Upload documents — sale deed, mutation certificate, architectural drawings (in prescribed format, usually DWG/DXF)
6. Auto-scrutiny — the system checks the building plan against bylaws automatically (in OBPS-enabled cities)
7. Pay the scrutiny fee online
8. Track application — the system routes it to relevant departments (town planning, fire, environment)
9. Receive approval — digitally signed building permission is issued online

States/Cities on OBPS

Most major cities and states have integrated with OBPS or have their own online portals:

• Delhi: dpms.mcdonline.nic.in
• Karnataka: bbmp.gov.in (Bengaluru)
• Maharashtra: umang.maharashtra.gov.in
• Telangana: tsobps.telangana.gov.in
• UP: Through respective development authority portals
• Tamil Nadu: tnepermit.gov.in

RERA Registration

If you are building a residential project with more than 8 units or a plot development exceeding 500 sq. metres, you must also register the project under RERA (Real Estate Regulatory Authority).

• National RERA portal: rera.gov.in
• RERA registration is separate from building plan approval
• It ensures buyer protection and project accountability
• The RERA registration number must be displayed in all project advertisements

Fees for Building Plan Approval

Note: Fees vary significantly by city, building type, and area. Use the calculator on your municipal corporation's website for exact amounts.

Processing Time

Under the Ease of Doing Business reforms, many cities have committed to approving building plans within 30 days for residential buildings through auto-scrutiny.

Step-by-Step Offline Process

1. Hire a licensed architect to prepare the building plan
2. Collect all land documents — sale deed, mutation, EC, land use certificate
3. Submit application at the municipal corporation/development authority office
4. Pay the scrutiny fee and development charges
5. Site inspection by the town planning officer
6. Compliance check — the plan is verified against building bylaws
7. NOCs from other departments — fire, environment, airport authority (if applicable)
8. Approval issued — building permission sanctioned with conditions
9. Commencement certificate — obtained before starting construction
10. Completion/occupancy certificate — obtained after construction is complete

Important Tips

1. Always hire a licensed architect — unlicensed plans will be rejected
2. Check FAR and setback norms before purchasing land — they limit how much you can build
3. Don't start construction before getting the approved plan — unauthorized construction can be demolished
4. Keep the approved plan on-site during construction for inspection
5. Apply for occupancy certificate after completion — needed for water, electricity connections and property sale

Frequently Asked Questions

Can I construct without building plan approval?

No. Constructing without approval is illegal. Unauthorized buildings can face demolition orders, heavy fines, denial of water/electricity connections, and the property cannot be legally sold or mortgaged.

How long is a building plan approval valid?

Building plan approval is typically valid for 3 years from the date of issue. If construction is not started or completed within this period, you must apply for renewal or a fresh approval.

What is FAR (Floor Area Ratio)?

FAR is the ratio of the total built-up area to the plot area. For example, if FAR is 2.0 and your plot is 1000 sq. ft., you can build up to 2000 sq. ft. of total floor area. FAR norms vary by city and zone.

What is the difference between building plan approval and occupancy certificate?

Building plan approval is permission to start construction. Occupancy certificate (OC) is given after construction is complete, certifying that the building was constructed as per the approved plan and is safe for occupation.

Do I need separate approval for compound wall?

In many municipalities, yes. Compound walls above a certain height (usually 1.5 metres) require permission. Check your local municipal bylaws.

What is auto-scrutiny in OBPS?

Auto-scrutiny is an automated system that checks the uploaded building plan (DWG/DXF file) against building bylaws. If the plan complies, approval is granted automatically without manual intervention, significantly reducing processing time.

Can I modify the building plan after approval?

Yes, but you need to apply for a revised plan approval before making changes. Deviating from the approved plan without permission is treated as unauthorized construction.
