Building Plan Approval Process in India

Building plan approval is the single most bureaucratic step in the house-building journey — and also the most critical. Without an approved plan, you cannot legally start construction, get utility connections, obtain an Occupancy Certificate, sell the property, or get a home loan against it.

India's building plan approval system has improved dramatically in the last decade. Most major cities now have online submission portals with automated bylaw checking (AutoDCR, eBPAS). Hyderabad's TS-bPASS even offers auto-approval within 21 days for plots under 500 sq.m. Yet the process remains confusing — every state has its own rules, every city has its own portal, and the documentation requirements vary significantly.

This guide covers the complete building plan approval process — from documents to submission to sanctions — for 20+ major Indian cities, with portal links, fee structures, bylaw summaries, and tips for avoiding the most common rejection reasons.

The General Approval Process

While each city has its own portal and specific rules, the overall process follows a common structure:

Step 1: Document Collection

Before approaching the planning authority, gather:

Step 2: Architectural Drawing Preparation

Your architect prepares the following drawings for submission:

Step 3: Online Submission

Most cities now accept online submission through their respective portals:

Step 4: Scrutiny & NOCs

Step 5: Fee Payment

Fees vary by city, zone, and built-up area. Common components:

Step 6: Approval / Sanction

Upon successful scrutiny, the authority issues:

• Building Plan Sanction Order — the approved plan with conditions
• Commencement Certificate (CC) — permission to start construction
• Validity — typically 3-5 years (varies by state). Must be renewed if expired.

Common Reasons for Rejection

---

After Approval — During and Post Construction

Inspections During Construction

Completion Certificate (CC) and Occupancy Certificate (OC)

Documents for OC:

• Completion certificate from architect
• Structural stability certificate
• Plumbing and drainage completion
• Electrical inspection certificate
• Fire safety certificate (if applicable)
• RWH completion certificate
• Solar installation certificate (if mandatory)
• Lift safety certificate (if applicable)
• As-built drawings (if any deviations from approved plan — requires revision sanction)

Tips for Smooth Approval

1. Hire a COA-registered architect. They know the bylaws and the approval process. This alone saves months.

2. Use online portals. Avoid manual submission wherever possible. Online systems have transparent tracking.

3. Get documents right the first time. Most rejections are due to incomplete or incorrect documentation.

4. Check bylaws before designing. Don't design first and check bylaws later. Start with the bylaws as constraints.

5. Verify road width officially. Don't assume road width from physical measurement — get it from the municipal records.

6. Apply for NOCs in parallel. Don't wait for plan approval to start NOC applications. Start them simultaneously.

7. Keep copies of everything. Every submission, every receipt, every communication — maintain a project file.

8. Don't deviate from approved plan. Any deviation during construction requires a revision sanction — which is another approval cycle.

9. Budget for approval fees. Fees can range from ₹50,000 to ₹5,00,000+ depending on city, zone, and built-up area.

10. Plan for time. Allow 2-4 months for the entire approval process in your project timeline.

Penalty for Unapproved Construction

Regularisation schemes are offered periodically by some states (Karnataka's Akrama-Sakrama, for example), but they are uncertain, time-bound, and involve heavy penalties. Never rely on future regularisation — get approval before construction.

Key Takeaways

• Building plan approval is legally mandatory — unapproved construction is illegal and carries severe consequences
• Every city has its own bylaws, portal, and process — verify the latest bylaws for your specific city before designing
• Online portals (AutoDCR, TS-bPASS, eBPAS) have made the process faster — use them instead of manual submission
• Hyderabad's TS-bPASS is the gold standard — 21-day deemed approval for small residential plots
• FSI, setbacks, height, and parking are the four most common rejection points — get them right in design itself
• Your architect handles the entire process — this is one of the key services you pay for
• NOCs can add 2-6 weeks each — apply in parallel, not sequentially
• Never deviate from the approved plan during construction — any change needs revision sanction
• Keep 10-15% of your timeline as buffer for the approval process
