How to Check Building Plan Approval in Chandigarh — Complete Guide 2026
A Building Plan Approval, locally called the Sanctioned Plan, is the official document showing that the Municipal Corporation or Estate Office has cleared a construction design. In Chandigarh, any deviation from the sanctioned plan makes the structure legally unauthorized. This guide covers how to get it, read it, and verify it before buying.
What is Building Plan Approval in Chandigarh?
Definition
A Building Plan Approval, or Sanctioned Plan, is the written permission from Chandigarh's Municipal Corporation or Estate Office confirming that a proposed construction design complies with the Chandigarh Building Rules (Urban) 2017, framed under the Capital of Punjab (Development and Regulation) Act, 1952.
Chandigarh is one of India's most strictly regulated urban territories. Le Corbusier's original master plan created sector-level zoning controls that still govern what can be built, how high, and with what setbacks. The Chandigarh Building Rules (Urban) 2017 codify these controls into enforceable law. Every residential, commercial, and industrial construction within the UT limits requires approval before any work starts. The plan must be drawn by an architect registered with the Council of Architecture, New Delhi, and submitted through the Online Building Plan Approval System known as OBPAS.
What makes Chandigarh different from other cities is the rigidity of its architectural control sheets. Each sector, each plot category has a frame control sheet that defines permissible coverage, floor area ratio, setbacks, and height. A builder cannot simply add a floor or extend a boundary wall without getting a revised plan sanctioned. Many properties in the city carry undisclosed deviations, and buyers pay the price when the Estate Office or Municipal Corporation later issues a notice. The Chandigarh Housing Board has served demolition orders on entire sectors, including Sector 41-A, where allottees were given seven days to remove violations before demolition began at their own cost and risk.
How to Get Building Plan Approval in Chandigarh: Step-by-Step
You can apply through the OBPAS portal at obps.chandigarhsmartcity.in or visit the Estate Office in Sector 17. Keep the plot allotment letter, architectural control sheet for your sector, and property documents ready before starting.

What Does Building Plan Approval Contain in Chandigarh?
The sanctioned plan is a technical document; know exactly what each field means before you verify it against the actual building.
| Field Name | What It Means | What to Check |
|---|---|---|
| Owner Name | Legal name of the plot owner as recorded in the allotment records | Must match the seller's name on the sale deed and identity documents exactly. |
| Plot Number and Sector | Unique plot identification within Chandigarh's sector layout | Cross-check with the allotment letter and physically verify that no portion of the plot falls within a road, green belt, or reserved area. |
| Sanctioned Ground Coverage | Percentage of the plot area approved for construction at ground level | Compare the sanctioned coverage with the actual building footprint. Excess coverage is an unauthorized deviation. |
| Floor Area Ratio (FAR) | Maximum total built-up area permitted across all floors | Review completion and occupancy records to ensure the constructed area does not exceed the approved FAR. |
| Sanctioned Number of Floors | Number of floors permitted under the approved building plan | Conduct a physical inspection to confirm that the existing structure matches the sanctioned floor count. Unauthorized floors may attract penalties or demolition orders. |
| Setbacks (Front, Rear, Side) | Mandatory open spaces that must remain clear along plot boundaries | Measure on-site and compare with the sanctioned plan. Encroachments into setback areas are among the most common building violations. |
| Approval Date and Reference Number | Date of sanction and unique file reference issued by the approving authority | Use these details to verify the plan's authenticity through the relevant approval records or authority database. |
