No construction project in India can legally begin without a sanctioned building plan. The building plan approval — also called plan sanction or building permission — is the formal confirmation by the local development authority that your proposed construction complies with applicable building bye-laws, development control regulations, fire safety norms, structural requirements, and zoning restrictions.
Yet this process remains one of the most opaque, time-consuming, and frustrating steps in Indian construction. Depending on the city, the same residential building may need approvals from 3 to 12 separate authorities, each with its own portal, fee structure, and processing timeline. A builder in Telangana can get instant approval for a small residential building through TG-bPASS, while a builder in Mumbai may spend months navigating BMC, Fire Department, AAI, and heritage clearances simultaneously.
India improved its World Bank Doing Business construction permits ranking from 52nd in 2019 to 27th in 2020 — a jump of 25 places — reflecting significant reform momentum across states. But the World Bank report was discontinued in 2021, and the on-ground reality still varies enormously between states, between cities within the same state, and even between different municipal zones within the same city.
This guide covers the complete building plan approval process in India — from the central framework under the Model Building Bye-Laws 2016, to state-wise approval processes across 15 major states, to the documents, NOCs, fees, timelines, Auto-DCR systems, common rejection pitfalls, and the occupancy certificate process that bookends the construction lifecycle.
The central framework — Model Building Bye-Laws 2016
The Ministry of Housing and Urban Affairs (MoHUA) published the Model Building Bye-Laws 2016 (MBBL 2016) through the Town and Country Planning Organisation (TCPO) as a template for states and urban local bodies to adopt. The MBBL does not have direct statutory force — each state must adopt or adapt it through its own legislation — but it establishes the national benchmark for building plan approval reform.
Key provisions that affect plan approval
Deemed sanction (Clause 2.14.2d): If the approving authority fails to respond within 15 days of receiving the notice, the building plan is deemed sanctioned — subject to conditions including the plot being in an approved layout and the applicant providing written notification. This provision exists to prevent indefinite bureaucratic delays but is not uniformly implemented across states.
Instant sanction by professional certification (Clause 2.14.1c): For buildings up to 15 metres height (17.5 metres with a 2.5-metre stilt floor) on individual plots in approved layouts, the MBBL provides for instant sanction based on professional certification. The certification panel requires 3 architects, 1 structural engineer, 1 proof consultant, and 1 services engineer. This route bypasses the authority's plan scrutiny entirely, placing accountability on the professional team.
Online building plan approval and Auto-DCR (Chapter 14): The MBBL mandates online automated plan scrutiny with Single Window integration as part of the Ease of Doing Business reforms. States are expected to implement automated Development Control Regulation (Auto-DCR) systems that check building plans against bye-laws algorithmically, reducing human discretion and processing time.
Green and sustainable building provisions: The MBBL includes provisions for rainwater harvesting, solar energy, waste management, and energy-efficient design — all of which may affect plan approval requirements depending on building size and location.
What MBBL 2016 means for practitioners
The MBBL is a model, not a mandate. When you apply for building plan approval, the rules that actually govern your application are the state-specific development control regulations and building bye-laws adopted by your local authority. However, states that have adopted MBBL provisions — particularly deemed sanction and online approval — offer significantly faster processing. Always check whether your state or ULB has adopted MBBL 2016 provisions before assuming they apply.
State-wise building plan approval process
Telangana — TG-bPASS / BuildNow (the reform benchmark)
Telangana's building permission system, originally launched as TS-bPASS in 2020 and rebranded as TG-bPASS (now BuildNow), is widely regarded as India's most reformed approval framework. It implements a three-tier system with statutory timelines.
Building permission tiers:
| Tier | Eligibility | Timeline | Process |
|---|---|---|---|
| No permission required | Residential plots up to 63 sq m (75 sq yards) | Instant | Online registration with Rs 1 token fee + self-certification |
| Instant approval | Plots up to 500 sq m, height up to 10 m | Instant | Self-certification by licensed professional |
| Single window | All other buildings (larger plots, non-residential, height above 10 m) | 21 days | Full scrutiny with deemed approval if deadline exceeded |
Statutory NOC timelines:
| NOC Type | Authority | Timeline |
|---|---|---|
| Fire NOC (provisional) | Fire Department | 14 days |
| AAI height clearance | Airports Authority of India | Instant (auto-computed) |
| NMA construction NOC | National Monuments Authority | Instant (auto-computed) |
| Police NOC | Police Department | 10 days |
| Irrigation FTL | Irrigation Department | 10 days |
| Revenue FTL | Revenue Department | 10 days |
| Water supply | HMWSSB | 10 days |
| Structural verification | JNTU/Osmania | 10 days |
Occupancy certificate tiers:
| Category | Requirement |
|---|---|
| Plots up to 200 sq m, height up to 7 m | OC not required |
| Plots above 200 sq m, height up to 10 m | Instant OC via self-certification |
| All others | 21-day OC with deemed approval |
The Telangana system's strength is its statutory backing — the TS-bPASS Act 2020 makes these timelines legally binding, and deemed approval kicks in automatically if the authority misses its deadline. Other states have announced similar reforms but few have enacted matching legislation.
Maharashtra — BMC / PMRDA / DCPR 2034
Maharashtra's building approval process varies by jurisdiction — BMC (Brihanmumbai Municipal Corporation) for Mumbai, PMRDA (Pune Metropolitan Region Development Authority) for Pune region, and various municipal corporations and councils for other cities. The Unified Development Control and Promotion Regulations (UDCPR) 2020 apply across the state except in Mumbai, where the Development Control and Promotion Regulations (DCPR) 2034 govern.
Mumbai (BMC) approval process:
High-rise buildings in Mumbai require multi-authority clearances:
| Authority | Clearance | When Required |
|---|---|---|
| BMC Building Proposal | Plan sanction, IOD (Intimation of Disapproval — actually the formal approval), CC (Commencement Certificate) | All buildings |
| Fire Department | Fire NOC | Buildings above 15 m height or above 24 m (high-rise) |
| Airport Authority of India (AAI) | Height clearance (NOCAS) | Buildings in airport funnel zone — mandatory within 20 km of aerodromes per GSR 751(E) |
| Heritage Conservation Committee | Heritage NOC | Buildings in heritage precincts (Grade I, II, III zones) |
| CRZ Authority | CRZ clearance | Buildings in CRZ zones along the coastline |
The licensed architect is accountable for FAR/FSI compliance, fire exits, refuge areas, and structural requirements. The architect also submits the completion certificate for OC issuance.
Mumbai's process typically involves:
- Title verification and property card extraction
- Preparation of building plans as per DCPR 2034
- Submission through the online portal
- Auto-DCR scrutiny for development control compliance
- NOC collection from parallel authorities (Fire, AAI, Heritage, CRZ as applicable)
- IOD issuance (the formal approval, despite the name)
- CC issuance after foundation work inspection
- Construction monitoring and stage inspections
- Full OC after building completion
Timeline: 60–120 days for straightforward residential; 6–12 months for complex high-rise or heritage zone projects.
Rest of Maharashtra (UDCPR 2020): Municipal corporations outside Mumbai follow the UDCPR 2020, which standardised development control regulations across the state. Auto-DCR systems are operational in Pune (PMC), Nagpur (NMC), Nashik, and other cities. The UDCPR introduced clearer FSI calculations, premium FSI provisions, and standardised setback tables.
Karnataka — BBMP / BDA (Bangalore)
Bangalore's building plan sanction involves BBMP (Bruhat Bengaluru Mahanagara Palike) for areas within BBMP limits and BDA (Bangalore Development Authority) for BDA layouts.
Documents required for BBMP plan sanction:
- Title deed (sale deed, gift deed, or partition deed)
- Khata certificate and Khata extract (A-Khata mandatory for plan sanction)
- Encumbrance certificate (typically last 13–30 years)
- Revenue sketch (from Survey Department)
- Property tax receipts (up to date)
- Site plan and building plan drawn by licensed architect
- Structural stability certificate (for buildings above G+2)
- NOCs: BDA layout NOC, BWSSB (water supply), BESCOM (electricity), ULC (Urban Land Ceiling — indemnity bond), Fire Department (buildings above 15 m)
- BBMP Schedule II (Bye-laws No. 3-2-1) submission form
Note on the ULC indemnity bond: The Karnataka Urban Land (Ceiling and Regulation) Act 1976 was repealed in 1999, but BBMP continues to require an indemnity bond under this act as a vestigial bureaucratic requirement. Practitioners report this is still a mandatory submission document.
Khata complications: Bangalore properties have A-Khata (revenue-recorded) or B-Khata (not in approved layout) status. BBMP plan sanction requires A-Khata. Properties with B-Khata status need conversion before plan sanction can proceed, which adds significant time.
Process flow:
- Document collection and verification
- Licensed architect prepares building plan per zonal regulations
- Online submission through BBMP BPAS portal
- Auto-DCR scrutiny
- Site inspection by BBMP officials
- NOC collection from BDA, BWSSB, BESCOM, Fire Department
- Plan sanction order issuance
- CC application after foundation
Timeline: 45–90 days for residential; longer for commercial or multi-authority clearances.

Fee structures across states
Building plan approval fees vary significantly by state and are typically calculated based on built-up area, building use (residential, commercial, industrial), and location (metropolitan, urban, rural).
Common fee components:
| Fee Type | Typical Range | Basis |
|---|---|---|
| Scrutiny fee | Rs 3–50 per sq ft | Built-up area, varies by state |
| Development charges | Rs 50–500 per sq m | Infrastructure contribution |

These are indicative ranges. Actual fees depend on the specific municipal body, plot location, FSI utilised, and applicable premium charges. Always verify current fee schedules from the local authority's official portal.
Auto-DCR and online approval systems
Auto-DCR (Automated Development Control Regulation) systems use software to automatically check building plans against applicable development control regulations. Instead of a manual officer reviewing drawings for setback compliance, FSI calculation, height limits, and parking requirements, the software reads the CAD file and flags violations.
States with operational Auto-DCR systems
| State / City | System | Status |
|---|---|---|
| Maharashtra (Mumbai, Pune, Nagpur) | Auto-DCR (MCGM, PMC, NMC portals) | Operational, mandatory for submissions |
| Telangana (all ULBs) | TG-bPASS / BuildNow | Operational, tiered instant/21-day |
| Karnataka (BBMP) | BBMP BPAS with Auto-DCR | Operational |
| Tamil Nadu (DTCP, CMDA) | OBPAS with Auto-DCR | Operational |
| Delhi (DDA) | OBPAS with CAD scrutiny | Launched 2026 |
| Gujarat (major cities) | Online BPA with DCR checks | Operational in major ULBs |
| Uttar Pradesh (NOIDA, Greater NOIDA, Lucknow) | Online building plan approval | Operational |
| Kerala | Sanketham | Operational in most local bodies |
| Andhra Pradesh | APCFSS online portal | Operational |
How Auto-DCR works in practice
- The architect prepares the building plan in CAD software following the prescribed layer naming conventions
- The CAD file is uploaded to the portal along with required documents
- The Auto-DCR engine reads the layers and calculates FSI, ground coverage, setbacks, height, parking, and other parameters
- The system generates a compliance report highlighting violations (if any)
- If compliant, the application moves to NOC collection and final approval
- If non-compliant, the system specifies exactly which parameters are violated, allowing the architect to correct and resubmit
Benefits for practitioners:
- Transparent, rule-based checking (no subjective interpretation)
- Faster processing (Auto-DCR check takes minutes, not weeks)
- Clear violation reports with specific parameter references
- Reduced scope for discretionary delays
Practical challenges:
- CAD file preparation requires strict layer naming conventions — non-compliant files are rejected
- Not all building types or irregularly shaped plots are handled well by automated systems
- Special provisions, variances, and exemptions often still require manual processing
- System downtime and portal issues can cause delays
Common rejection reasons and how to avoid them
Building plans are most commonly rejected for the following reasons, verified across multiple state portals and practitioner reports:
1. FSI / FAR violations
The single most common rejection reason. Floor Space Index (FSI) or Floor Area Ratio (FAR) violations occur when the proposed built-up area exceeds the permissible limit for the plot.
Common FSI calculation pitfalls:
- Chajja overhangs: Projections (chajjas/balconies) exceeding 0.75 m are counted toward FSI under UDCPR 2020 and similar regulations. Many architects assume all chajjas are exempt.
- Parking podiums: Stilt parking floors exceeding the specified height threshold (2.4 m in most regulations, 3 m in some Bangalore zones) lose their FSI exemption.
- Terrace coverage: Covered terrace areas above the allowable percentage are counted as additional FSI.
- Basement area: Basements used for purposes other than parking/utilities may attract FSI calculation.
How to avoid: Verify FSI calculations independently against the specific DCR version applicable to your plot. Do not rely on assumptions from adjacent plots or older projects — regulations change.
2. Setback non-compliance
Required setbacks (front, side, rear) depend on plot size, road width, building height, and use. Non-compliance with any setback margin triggers rejection.
How to avoid: Cross-reference setbacks with the applicable development control regulation table for your exact plot size and proposed building height. Remember that setback requirements may increase with height.
3. Insufficient road width
Many DCRs limit building height based on the width of the road abutting the plot. A 6-metre road may permit only G+2, while a 12-metre road may allow G+5 or more.
How to avoid: Verify the official road width from the municipal records, not from site measurement. The recorded road width (as per the master plan) may differ from the actual width on ground.
4. Disputed or encroached land
If the plot has any pending litigation, encroachment, or boundary dispute, plan sanction will not be granted.
How to avoid: Obtain an up-to-date encumbrance certificate, verify the title through a legal opinion, and ensure the revenue records (khata/patta) match the site survey.
5. Incomplete or wrongly scaled drawings
Plans submitted without required views (floor plans, sections, elevations), at incorrect scales, or with missing dimensions are rejected at the preliminary scrutiny stage.
How to avoid: Follow the drawing format specified by the local authority (most publish submission checklists). Ensure all mandatory details — setback dimensions, floor areas, staircase widths, parking layout, rainwater harvesting provision — are clearly shown.
6. Missing NOCs
Particularly for buildings requiring Fire NOC, AAI height clearance, or environmental clearance — submitting the building plan without these parallel clearances delays approval.
How to avoid: Start NOC applications simultaneously with plan preparation. Fire NOC and AAI clearance can be applied for before plan sanction in most jurisdictions.
7. Heritage or zoning violations
Properties in heritage zones, eco-sensitive areas, defence zones, or airport funnel zones have additional restrictions that are sometimes overlooked.
How to avoid: Before starting design, verify whether the plot falls under any overlay zones — heritage, CRZ, ESA, airport funnel, defence — by checking the master plan and relevant authority portals.
The occupancy certificate and completion certificate process
The Occupancy Certificate (OC) is the final regulatory approval that confirms the completed building was constructed as per the sanctioned plan and is safe for occupation. Without an OC, the building cannot be legally occupied.
Consequences of not having an OC
Verified legal consequences across Indian jurisdictions:
- Cannot legally occupy: RERA Section 18 mandates that possession can only be given after obtaining an OC. The Bombay High Court has directed action against flat owners occupying buildings without OC.
- Cannot register property: Sub-registrars require OC for sale deed registration in most states.
- No permanent utility connections: Water, electricity, and gas providers require OC for permanent connections.
- Cannot secure bank loans: Banks require OC for final home loan disbursement and for resale property loans (construction-stage loans are an exception where interim disbursements are made against CC).
- Cannot effectively sell or rent: Without registration, the property cannot be formally transacted.
- Risk of forced demolition: In extreme cases, courts have upheld demolition of structures without OC — the Bombay High Court has upheld such orders.
OC application process (general pattern)
- Completion of construction as per sanctioned plan
- Completion certificate submitted by the licensed architect/engineer certifying that construction matches the approved drawings
- Structural stability certificate from the structural engineer
- Fire safety compliance certificate (for buildings above 15 m or as applicable)
- Lift safety certification from the Chief Inspector of Lifts (where applicable)
- Water and sewerage connection confirmation
- Rainwater harvesting compliance verification
- Solar energy installation verification (where mandated)
- Site inspection by the approving authority
- OC issuance — full OC for the entire building or part OC for completed floors/wings
State-specific OC variations
- Telangana: Tiered OC system — not required for plots up to 200 sq m / 7 m height; instant for plots up to 500 sq m / 10 m; 21-day for larger buildings.
- Maharashtra: BMC issues OC after completion certificate from the architect, fire compliance certificate, and inspection. Part OC available for phased projects.
- Karnataka: BBMP issues OC after inspection and verification against sanctioned plan. Deviation regularisation possible for minor deviations in some cases.
- Gujarat: BU (Building Use) permission serves as the occupancy certificate.
- Delhi: MCD/DDA issues OC after inspection. Mandatory structural safety certificate for buildings above 4 storeys.
Role of the registered architect and structural engineer
Who can submit building plans
In most Indian states, building plans must be submitted by a registered architect (registered with the Council of Architecture under the Architects Act 1972) or a licensed engineer/supervisor (for smaller buildings, typically below a specified height or area threshold).
Typical licensing hierarchy:
| Professional | Qualification | Building Size Limit |
|---|---|---|
| Registered Architect (COA) | B.Arch + COA registration | No limit — can submit for any building size |
| Licensed Structural Engineer | B.E./B.Tech Civil + state registration | No limit for structural work; some states require architect co-signing for design |
| Licensed Building Supervisor | Diploma / Certificate + state registration | Typically limited to G+1 or G+2 residential buildings |
Professional accountability
The licensed architect or engineer who submits the building plan is professionally and legally accountable for:
- Design compliance: Ensuring the design meets all applicable development control regulations
- Structural adequacy: Certifying (or co-certifying with the structural engineer) that the structure is safe
- Construction supervision: Periodic site visits to ensure construction follows sanctioned drawings
- Deviation reporting: Reporting material deviations to the approving authority
- Completion certification: Submitting the completion certificate for OC issuance
The professional is liable for any discrepancy between the sanctioned plan and the actual construction. In cases of structural failure or non-compliance, the architect/engineer can face license suspension, criminal proceedings, and civil liability.
Practical checklist — before you start the approval process
Use this checklist to ensure your application is complete before submission:
Pre-design verification:
- Verify land ownership and obtain up-to-date encumbrance certificate
- Check the master plan for zoning and land use classification
- Verify road width from municipal records (not site measurement)
- Check for overlay zones: heritage, CRZ, ESA, airport funnel, defence, flood zone
- Obtain NA permission if land is agricultural
- Verify Khata/Patta status and update if needed
Design preparation:

FAQs
What is the difference between IOD, CC, and OC in Mumbai
IOD (Intimation of Disapproval) is actually the formal building plan approval in Mumbai — despite its misleading name, it is the sanction order listing conditions to comply with. CC (Commencement Certificate) is the permission to start construction, issued after foundation work inspection and compliance with IOD conditions. OC (Occupancy Certificate) is the final approval confirming the completed building matches the sanctioned plan and is fit for occupation.
Can I start construction before getting building plan approval
No. Starting construction without a sanctioned building plan is illegal in all Indian states. Unauthorised construction can be demolished by the municipal authority, and the owner, architect, and contractor can face penalties including fines and imprisonment under the relevant state municipal act.
What is deemed approval and when does it apply
Deemed approval means the building plan is automatically considered sanctioned if the approving authority fails to process the application within the prescribed timeline. MBBL 2016 provides for deemed sanction within 15 days. However, deemed approval typically applies only to applications that are complete in all respects, meet all development control norms, and are on plots within approved layouts. States that have adopted this provision may have different timelines.
How long does the entire process take from plan submission to OC
For a straightforward residential building on a clear-title plot in an approved layout, with all documents ready: 3–6 months from plan submission to OC. For complex projects (high-rise, multiple authorities, CRZ/heritage zone, environmental clearance required): 12–24 months or more. The largest variable is NOC collection — Fire, AAI, and environmental clearances run in parallel but each has its own processing timeline.
Is an architect mandatory for all buildings
In most states, a COA-registered architect is mandatory for buildings above a specified size (typically above G+1 or 200 sq m built-up area). For smaller residential buildings, a licensed supervisor or engineer may be permitted to submit plans. However, engaging a registered architect even for small buildings is strongly recommended because they understand the DCR compliance requirements.
What happens if the completed building deviates from the sanctioned plan
Minor deviations (typically less than 5% in area or non-structural changes) may be regularised by paying a compounding fee in some states. Major deviations — exceeding FAR, violating setbacks, adding unauthorised floors — can result in demolition orders, penalties, and refusal of OC. RERA-registered projects face additional consequences including project de-registration.
Do I need separate approvals for interior changes or renovations
Interior changes that do not alter the external structure, FSI, or use of the building generally do not require fresh building plan approval. However, changes that add built-up area, alter the structural system, change the building use (residential to commercial), or affect fire safety provisions require fresh or amended approval.
How do I check if my property falls in an airport funnel zone
The Airports Authority of India operates the NOCAS (No Objection Certificate Application System) portal where you can check height restrictions for any location near Indian airports. The portal uses GPS coordinates to determine the applicable height ceiling. Properties within 20 km of an aerodrome are subject to height clearance requirements under GSR 751(E). Check the NOCAS portal before finalising building height.
What is the cost of hiring an architect for building plan approval
Architect fees for building plan preparation and approval vary by city and project size. For residential buildings, expect Rs 15–40 per sq ft for architectural design and approval processing. For commercial buildings, Rs 25–60 per sq ft. These fees typically cover design, drawing preparation, authority submission, query response, and OC assistance. Structural engineer fees are additional, typically Rs 5–15 per sq ft.
Can building plan approval be transferred to a new owner
Yes, in most states. If the property is sold after plan sanction but before or during construction, the building permission can be transferred to the new owner. The process requires an application to the approving authority with the sale deed, transfer deed, and an undertaking by the new owner to comply with all sanction conditions. A nominal transfer fee is typically charged.
How construction management software supports the approval process
Building plan approval is the starting point, but maintaining compliance through construction and achieving OC requires disciplined document management and execution tracking throughout the project lifecycle.
- Document management: Store and version-control all approval documents — sanctioned drawings, NOCs, structural calculations, architect certificates — in a centralised system accessible to the entire project team
- Drawing revision control: Track sanctioned drawing revisions and ensure site teams are working with the latest approved version — a common source of OC-stage discrepancies
- Inspection scheduling: Schedule and document mandatory stage inspections (foundation, plinth, each floor) that the approving authority requires before issuing CC and OC
- Deviation tracking: Flag construction deviations from the sanctioned plan early, when correction is possible, rather than discovering them at OC stage
- Quality documentation: Maintain photographic evidence of construction quality, material test certificates, and compliance records that the authority may request during OC inspection
- Timeline tracking: Monitor approval expiry dates (most building permissions are valid for 2–3 years) and renewal deadlines
- Multi-authority coordination: Track parallel NOC applications and their status across multiple authorities — Fire, AAI, environmental, water, electricity — to identify bottlenecks early
Whether you are a builder managing multiple projects across different municipal jurisdictions, or an architect tracking approval status for client projects, systematic documentation from plan sanction through occupancy certificate reduces the risk of delays, rejections, and compliance gaps at every stage.
