Building Plan Approval Roadmap

Building Plan Approval in India — A Working Roadmap by City

Building plan approval is the regulatory gateway for any Indian construction project. Without it, the work is unauthorised — exposing the owner to demolition orders, withheld utility connections, denial of occupancy certificate, and complications at resale. The approval is granted by the local municipal corporation or development authority, after verification that the proposed building complies with the sanctioned land use, FAR (Floor Area Ratio), setback requirements, height limits, parking provisions, fire safety, and other applicable regulations under the National Building Code 2016 and state bye-laws.

India does not have a single building approval framework — it is genuinely city-by-city. The authority structure, document checklist, fees, and timelines differ across Bengaluru (BBMP under Karnataka Town and Country Planning Act 1961), Mumbai (MCGM under DCPR 2034), Delhi (multiple authorities — DDA, SDMC, NDMC, EDMC under DDA Act 1957 and MCD Act 1957), Chennai (CMDA + GCC), Hyderabad (HMDA / GHMC under TS-bPASS framework), and others.

City-by-City Comparison

The Standard Approval Process — Eight Universal Steps

1. Title and tax verification — Sale deed, encumbrance certificate, Khata/Patta/7-12 extract, tax-paid receipts, mutation up to date.
2. Land-use verification — Confirm plot is in residential / commercial zone per master plan; not in revenue / agricultural / forest / eco-sensitive zone.
3. Architect engagement — Engage COA-registered architect (mandatory under Architects Act 1972 §37). Architect prepares plans, sections, elevations, and FAR / setback compliance certificate.
4. Soil investigation — Required for buildings above ground floor in most states. SBC (Safe Bearing Capacity) report from a NABL-accredited lab.
5. Structural engineer engagement — Licensed structural engineer signs structural drawings and design.
6. Application submission — Online via municipal portal (BBMP NBPDP, MCGM AGNI, HMDA DPMS, etc.) with full document set + fee payment.
7. Query response and revision — Most submissions enter a query loop; respond promptly and resubmit. Sakala framework caps the timeline.
8. Sanction issuance — Plan is approved; construction can begin. Plinth verification follows after foundation work.

Common Pitfalls That Delay Approvals

• B-Khata in Bengaluru — applies to ~30% of Bengaluru plots; cannot get standard sanction without A-Khata conversion (6-18 months).
• Conflicting authorities in BMRDA / BDA / BBMP boundary zones — verify exact authority before applying.
• Missing or expired documents — encumbrance certificate older than 6 months, tax receipts for prior years, mutation not updated post-purchase.
• Plan-versus-bye-laws non-compliance — exceeding FAR, encroaching setbacks, parking shortfall, height-limit violation. The architect's job; verify with the [Bylaw Checker](/utilities/bylaw-checker) and [Far/FSI Calculator](/utilities/far-fsi-calculator) before plan finalisation.
• Heritage or coastal overlays — additional NOC requirements that add 60-90 days; verify zone before applying.
• Tree-cutting permission missing — required wherever trees on plot, often skipped, blocks plan sanction in eco-conscious cities.

Fees and Charges — A Working Range

Building plan sanction fees vary widely. As a rough range for a typical 2,500-4,000 sqft residential project: ₹50,000-3,00,000 in plan-sanction fees, scrutiny fees, and infrastructure charges. Mumbai is the most expensive (premium FSI + fungible FSI charges can add lakhs to crores for high-FAR projects). Hyderabad and Bengaluru are mid-range. Delhi varies by zone. Tier-2 cities are typically 30-50% lower than Tier-1.
