A Building Plan Approval ID (or Building Permit Number) is the authorization code issued by a local development authority or municipal corporation allowing a builder or owner to start construction. Before a single brick is laid, the architectural plan of the building must be submitted to the town planning department. Once verified against safety and zoning norms (bylaws), an approval ID is generated.
When you ask “what is Building Plan Approval ID,” you are asking for the proof that the building is legal. Construction without this ID is considered unauthorized and risks demolition or heavy penalties.
What Does Building Approval ID Mean?
It represents the formal “Commencement Certificate” (CC). It signifies that:
- The building height and setbacks are within legal limits.
- The structural plan is safe.
- The land usage is correct (e.g., not building a factory in a residential zone).
For apartment buyers, this number is the most critical thing to check in the builder’s brochure. It usually looks like a long alphanumeric code referencing the file number of the authority (e.g., BBMP, CMDA, DDA).
Why Building Plan Approval ID is Important
Buying a property without checking this ID can be disastrous:
- Legality: Illegal floors (penthouses) often do not have this approval. If you buy one, you can never get a legal electricity meter or Khata.
- Home Loans: Banks verify this ID on the “Sanctioned Plan” before disbursing loans.
- Occupancy Certificate (OC): You cannot get an OC after completion if you didn’t have a Plan Approval ID to start with.
- Resale: Future buyers will demand this document.
Where is Building Approval ID Used?
- RERA Registration: Builders must quote this ID to register their project under RERA.
- Site Hoardings: It is legally mandatory to display the Plan Approval Number on a board at the construction site.
- Sale Agreement: It must be mentioned in the construction agreement.
How to Find or Check Building Approval ID
Step 1: Check the RERA Website
Since RERA (Real Estate Regulatory Authority) is mandatory, the easiest way is:
1. Go to your state’s RERA website (e.g., MahaRERA).
2. Search for the project name.
3. Look under “Project Details” or “Approvals” to find the Building Plan Approval Number/Date.
Step 2: Municipal Portal
Many cities like Chennai (CMDA) or Bangalore (BBMP) list approved plans online. Search by village or survey number.
Example of Building Approval ID
Example (Bangalore): BBMP/Addl.Dir/JD NORTH/0012/2023-24
Example (Chennai): PP. No. 1234/2023
Common Problems or Errors
- Deviations: The builder has an Approval ID for 4 floors but builds 5. The ID is valid only for the approved 4 floors. Always compare the actual building with the sanctioned plan.
- Expired Plan: Approval is usually valid for 2-3 years. If construction isn’t finished, the ID must be renewed.
Important Things to Remember
- Just having an ID isn’t enough; ensure the building matches the plan associated with that ID.
- Do not confuse this with Property ID; Property ID is for tax, Approval ID is for construction permission.
- For commercial buildings, also check Trade License Number requirements.
Before buying land for construction, verify the survey number to ensure the title is clear.
Frequently Asked Questions
Can I start construction without a Building Plan Approval ID?
No, it is illegal. The municipal authorities can demolish unauthorized construction at any stage and impose heavy fines.
How long is the building plan approval valid?
Typically, it is valid for 2 to 3 years depending on the state bylaws. If construction is not completed, you must apply for a renewal.
Is Building Approval ID required for a small house on a small plot?
Yes, even for small independent houses, you need approval from the local Panchayat or Municipality. The rules might be simpler, but approval is mandatory.
What is the difference between Plan Approval and Layout Approval?
Layout Approval is for the entire land/colony (roads, parks), while Building Plan Approval is for the specific structure constructed on a plot within that layout.
Where can I complain if a builder is building without approval?
You can file a complaint with the town planning department of your local municipal corporation or report it on the state’s RERA portal if it is a registered project.
