Getting a building plan approval in Karachi is the step that legally allows you to start construction — and it is the one owners most often leave too late. In Karachi the approving authority depends on where your plot is: the Sindh Building Control Authority (SBCA) covers most of the city, while cantonment boards, DHA and Bahria Town run their own approvals. Identity Interior, a construction company in Karachi, handles drawing, approval and construction as one process, and this guide explains the 2026 process in plain terms.

Who Approves Building Plans in Karachi?
| Plot location | Approving authority |
|---|---|
| Most KMC / city areas (Gulshan, North Nazimabad, PECHS, etc.) | Sindh Building Control Authority (SBCA) |
| DHA (Phases and extensions) | DHA Building Control / DHA office |
| Bahria Town Karachi | Bahria Town Building Control |
| Cantonment areas | Relevant Cantonment Board |
Always confirm the authority for your specific plot number, because two adjacent plots can fall under different controls. This is something your construction company should verify before drawing begins.
Documents and Drawings You Need
- Ownership documents (allotment letter / lease / sale deed) and transfer record
- Copy of the approved layout plan / plot map
- Architectural drawings (floor plans, elevations, sections) to scale
- Structural (RCC) design signed by a registered structural engineer
- Services drawings (plumbing, electrical, drainage) where required
- No-dues / tax clearance and authority fee challans
Byelaws an Approval Checks
- Coverage: how much of the plot you may build on (leaves the rest open).
- Setbacks: mandatory open space from boundary walls.
- Height & storeys: limits driven by plot size and road width.
- FAR / FSI: ratio of covered area to plot area.
- Basement limits: depth and coverage rules (see basement construction).
- Parking and amenities for larger plots.
Step-by-Step Approval Process
- Confirm the approving authority for your plot.
- Engage an architect to produce drawings to the authority’s byelaws.
- Get the structural design prepared and signed.
- Submit the drawing set, documents and fee; obtain a submission receipt / file number.
- Respond to any objections (often coverage, setbacks or drawing corrections).
- Receive the approved / sanctioned plan.
- Display the approved plan on site and keep a copy for inspections.
- Apply for completion / occupancy certificate after construction.
Common Reasons Plans Get Rejected or Delayed
- Coverage or setbacks exceeding byelaw limits.
- Incomplete documents or missing structural design.
- Drawings that do not match the plot dimensions or layout plan.
- Unpaid dues or fee shortfalls.
- Submitting before confirming the correct authority.
Frequently Asked Questions
How long does building plan approval take in Karachi?
Typically a few weeks to a few months, depending on the authority and how complete the submission is. Objections and corrections are the main cause of delay.
Can I start construction before approval?
No. Building without an approved plan risks stop-work notices, penalties and demolition, and it makes utility connections and later resale harder.
Who approves plans in DHA and Bahria Town Karachi?
DHA and Bahria Town run their own building control offices, not SBCA. Always confirm for your specific plot.
