Understanding Building plan sanction / development permission

Get your building plan sanctioned by the municipal corporation before starting any construction.

At a glance

Jurisdiction

India — municipal corporations and development authorities; procedure follows National Building Code 2016 and local building by-laws; patterns for BBMP (Bengaluru), MCGM (Mumbai), BDA (Bengaluru Development Authority), DDA (Delhi), and DTCP (Tamil Nadu) described

Who applies

Owner or developer intending to construct a new building, add a floor, extend an existing building, or change the use of a structure within the limits of a municipal corporation or development authority; construction without sanction is illegal under all state municipal laws

Typical time

BBMP Bengaluru: 30–60 days (online DPMS). MCGM Mumbai: 60–120 days. BDA / DTCP: 45–90 days. Large projects with multiple NOCs: 6–18 months. Under RERA-mandated timelines in some states: 60 days for residential

Fee

Development charges: Rs 100–Rs 600 per sq ft (city and zone dependent). Scrutiny fee: Rs 5–Rs 50 per sq ft. Labour cess (BOCW): 1% of project cost. Total fees on a 2,000 sq ft house can range from Rs 50,000 to Rs 5 lakh depending on city and zone

Who should use this process

  • Applicant must be the registered owner of the land or hold a registered lease/development agreement
  • Land must be legally converted to residential/commercial/industrial use as applicable (agricultural land requires prior conversion order)
  • Land must have a valid Khata or property record in the municipal body's name
  • Building plan must be prepared by a licensed architect or engineer registered with the Council of Architecture
  • All prerequisite NOCs (Fire, AAI, Water Board, Environmental) must be in hand before plan submission
  • Property must not be under acquisition notice, court attachment, or legal dispute

Who does NOT need to apply

  • Constructions below a specified threshold area or height may be allowed under 'self-declaration' scheme in some states (e.g., BBMP allows construction up to 600 sq ft on sites up to 600 sq ft under simplified process)
  • Heritage buildings and properties in heritage zones require clearance from Heritage Conservation Committee in addition to building plan sanction
  • Constructions in CRZ zones, forest buffer zones, or defence areas have stricter or additional requirements

Step-by-step guide

  1. 1

    Engage a licensed architect and prepare building plans

    Offline

    Hire an architect registered with the Council of Architecture (COA). The architect prepares site plans, floor plans, elevations, and sections in compliance with local building by-laws (Floor Space Index/FAR, setbacks, height limits, parking norms). Get a structural engineer to review and certify the structural design.

    15–30 days
  2. 2

    Obtain all prerequisite NOCs

    Both

    Identify and obtain all mandatory NOCs required for the project type and location (Fire, AAI, Water Board, Environmental). These must be in hand before or along with the plan submission. Some cities allow conditional submission pending NOC.

    15–180 days depending on NOC type
  3. 3

    Submit building plan application online (DPMS / municipal portal)

    Online

    In Bengaluru, submit via the BBMP DPMS (Development Permission Management System) portal at bbmpdpms.karnataka.gov.in. In Mumbai, use the BMC DCR portal. Upload all drawings in prescribed format (DWG/PDF), fill in built-up area, setbacks, FSI consumed, and upload all support documents. Pay scrutiny fee online.

    1–2 dayshttps://bbmpdpms.karnataka.gov.in (Bengaluru); https://mcgm.gov.in (Mumbai)
  4. 4

    Plan scrutiny by junior engineer / town planner

    Both

    The submitted plans are assigned to a junior engineer (JE) or assistant executive engineer (AEE) who scrutinises the drawings for compliance with local by-laws — FSI, setbacks, parking, fire exits, accessibility. Queries or objections are raised online; the applicant must respond within the stipulated period.

    15–45 daysJunior Engineer / Assistant Executive Engineer
  5. 5

    Field inspection by engineering staff

    Offline

    An engineer or inspector visits the site to verify land dimensions, confirm no existing illegal structures, and check ground conditions. The inspection report is uploaded to the portal and forms part of the sanction process.

    7–21 days after scrutinyJunior Engineer / Revenue Inspector
  6. 6

    Pay development charges and labour cess

    Online

    After plan scrutiny approval, the system generates a demand notice for development charges, infrastructure development charges (IDC), and any other applicable levies. Pay these online via the portal. Also pay BOCW cess of 1% of the construction cost to the state Labour Welfare Board.

    1–2 days
  7. 7

    Receive sanctioned building plan

    Online

    After all queries are resolved, fees paid, and inspection completed, the competent authority issues the sanction order (Development Permission Order / Building Permission). The approved plan is stamped and signed by the engineer/officer. Download the sanctioned plan and permission order from the portal.

    7–30 days after inspection and fee paymentExecutive Engineer / Commissioner (Buildings)
  8. 8

    Display sanction notice at site and commence construction

    Offline

    Display the sanctioned plan and permission certificate at the construction site as required by law. Commence construction strictly as per the approved plan. Any deviation requires a revised plan sanction before implementing the change.

Things to watch out for

Unauthorised construction faces demolition and heavy fine

Constructing without a sanctioned plan or deviating from the approved plan is a punishable offence under state municipal acts. Municipal corporations issue show-cause notices and can demolish unauthorised portions. Regularisation schemes (if available) are expensive and not guaranteed.

FSI/FAR must be computed correctly — violations are common

Floor Space Index (FSI or FAR) determines how much you can build on a plot. Miscalculating FSI (by not including or excluding the right components) leads to approval of excess construction or rejection of plans. Get the FSI calculation verified by an experienced architect familiar with local by-laws.

Sanctioned plan must be strictly followed during construction

Any deviation — additional floor, change in staircase position, balcony extension — constitutes an offence. Apply for a revised/modification plan before implementing any change. Deviations found during OC inspection lead to rejection of Occupancy Certificate.

Plan sanction has a time limit — typically 2–5 years

Building permission is valid for a specified period (usually 2–5 years, varying by city). If construction is not completed within this period, the sanction lapses and renewal must be applied for. Building post-lapse is considered unauthorised.

Commencement Certificate must be obtained before starting foundation

In many cities (Mumbai, Delhi), a separate Commencement Certificate (CC) or Notice of Commencement must be filed with the authority before breaking ground, even after plan sanction. Skipping this step can result in sealing orders on the construction site.

Building plans must be retained permanently

Sanctioned building plans are required for future sale, loan, OC application, and alterations. Keep the original stamped approved plan and all permission orders safely. Loss of plans requires obtaining certified copies from the municipal authority, which can be time-consuming.
