If you are planning construction in Kolkata, the sanctioned building plan is the document that confirms the Kolkata Municipal Corporation (KMC) has approved the proposal. This guide explains how to search for a sanctioned plan, track a current proposal, obtain a certified copy, and avoid common approval delays.
Quick answer
Use KMC’s official Sanctioned Plan Search for an approved plan record. To track an application still under review, use the separate Building Plan Proposal Status page. A searchable record is not the same as a certified plan copy.
KMC Sanctioned Plan Search: Official Portal
Open the official KMC Sanctioned Plan Search page and enter the property or case details requested on the form. Use the information exactly as it appears on your KMC records. This service is meant for sanctioned plan records; it should not be confused with the proposal-status service used while an application is being processed.

If the sanctioned plan does not appear
- Check spellings, property identifiers, case details, and year carefully.
- Ask the owner or licensed professional for the sanction or case reference shown on the application records.
- Contact the relevant KMC Building Department office if an older record is unavailable online.
- Apply separately for a certified copy when you need an official copy for legal, loan, sale, or construction purposes.
How to Check KMC Building Plan Proposal Status
If the plan has been submitted but is not yet sanctioned, use KMC’s Building Plan Proposal Status service. Keep the application or proposal reference available. The result can help you identify the current status, but any objection or document request should be handled with the professional responsible for the submission.
How to Get a Certified Copy of a Sanctioned KMC Plan
KMC’s Building Department Citizens’ Charter describes a separate process for obtaining a certified copy of a sanctioned building plan. It says the applicant should submit a plain-paper application with documents supporting ownership to the Executive Engineer (Head Quarter). Fees apply according to the current KMC schedule.
The Citizens’ Charter lists an indicative service time of 30 working days for a certified copy. Treat this as official guidance rather than a guaranteed completion date, and confirm the current requirements and fee before submitting.

What to keep ready
- A plain-paper application explaining the request
- Documents supporting ownership of the property
- Available plan, premises, case, or proposal references
- Contact details for follow-up
- The applicable fee after confirmation from KMC
KMC Building Plan Approval: Main Steps
- Confirm the property details. Verify ownership records, municipal premises details, land use, road information, and applicable restrictions.
- Engage a qualified professional. A licensed building professional can prepare the drawings and coordinate the submission under the applicable KMC rules.
- Prepare the proposal. The submission may include architectural drawings, structural and service information, ownership documents, and other approvals relevant to the site and building.
- Submit and pay applicable fees. Fees depend on the proposal and the current municipal schedule.
- Respond to scrutiny. KMC may seek corrections, clarification, documents, or site-related information.
- Obtain and follow the sanctioned plan. Construction should follow the approved drawings and conditions. Changes should be regularised through the proper approval process before execution.
Online submission: checks before the professional submits
The KMC building-plan login page requires drawings prepared to its layer instructions, relevant records ready, and any required rule relaxation obtained before submission. It also specifies deadlines for completing online entry and delivering hard-copy documents. Ask the submitting LBS or architect to confirm those instructions immediately before applying and retain the final acknowledgement.
Start from the official Building Department hub for the current checklist, professional directories, circulars and fee links.
Documents Commonly Required
The exact list varies by property and proposal. Your professional should confirm the current checklist. Common records can include:
- Title deed or other ownership documents
- Municipal mutation and property-tax records
- Owner identity and contact information
- Site plan, floor plans, elevations, sections, and area statements
- Structural and service-related documents where applicable
- Additional clearances required because of the site, use, height, or project type
KMC building plan sanction fees: 2026–27
KMC publishes a 2026–27 Building Department fee schedule. Application fees are only one part of the total. For residential proposals on land up to 500 sq. m., its first-submission table lists:
| Proposed height | Application fee |
|---|---|
| Up to 7 metres | ₹2,000 |
| Above 7 and up to 10 metres | ₹5,000 |
| Above 10 and up to 12.5 metres | ₹11,000 |
Permit fees and other applicable charges are additional. Ask for an itemised estimate separating municipal charges from professional fees. Confirm the current demand before payment; do not use these examples as a quotation for your property.
How long does KMC approval take?
The published Citizens’ Charter lists 20 working days for verification, 7 for a demand notice and 4 after payment for the specified small-residential category, subject to its conditions. This is a service benchmark, not a guaranteed turnaround for every proposal. Confirm the current category and procedure with the Building Department. Keep a dated record of submissions, objections, replies and receipts to follow up effectively.
Common Reasons for Delay or Objection
- Mismatch between ownership, mutation, tax, and application records
- Incomplete drawings or missing supporting documents
- Incorrect area, setback, height, parking, or floor-area calculations
- Site conditions that do not match the submitted plan
- Missing clearances that apply to the particular property or project
- Unresolved queries raised during technical scrutiny
Before Starting Construction
- Keep a complete copy of the sanctioned drawings and approval conditions.
- Ask the architect or engineer to explain the approved footprint, setbacks, height, and permitted floor areas.
- Do not treat a proposal receipt or online status as final sanction.
- Record any required inspections, notices, and completion-stage documents.
- Use the latest municipal requirements because rules, procedures, and fees can change.
Frequently asked questions
How do I apply for KMC building plan approval?
Engage a KMC-licensed building surveyor or architect, prepare the drawings and supporting records, and follow the applicable online submission and scrutiny process. KMC issues the sanction after the required checks and payments; an application receipt is not permission to build.
Where can I search for a sanctioned KMC building plan?
Use the official KMC Sanctioned Plan Search linked above. Keep the property and case references ready. For a pending application, use Building Plan Proposal Status instead.
Is a sanctioned-plan search result a certified copy?
No. The online search and the request for a certified copy are separate services. The KMC Citizens’ Charter describes an ownership-supported application to the Executive Engineer (Head Quarter) for a certified copy.
What does KMC building plan approval cost in 2026–27?
There is no single flat fee. The current schedule separates application fees from building permit fees and other applicable charges. Plot area, proposed height, use, covered area and access conditions affect the calculation; confirm the demand for your proposal.
Is approval guaranteed within 30 days?
No. Processing depends on the application category, completeness and scrutiny. The charter’s 30-working-day entry concerns a certified plan copy, not a blanket deadline for every new building sanction.
Can I start construction while my proposal is pending?
Do not treat submission or a pending status as sanction. Obtain the applicable permission and confirm commencement requirements with the professional responsible for the project before starting work.
Do alterations to an existing building need permission?
KMC lists additions, alterations and structural changes among activities requiring permission. Some limited repairs have separate exemptions. Have your licensed professional check the exact work against the applicable rules before proceeding.
What should I do if KMC cannot find my plan online?
Recheck the premises details, reference and year with the owner or submitting professional. If the record remains unavailable, contact the appropriate KMC Building Department office and ask about record retrieval or a certified-copy request.
