Anyone building a house, adding floors or developing a project in Karachi outside DHA and the cantonments needs an approved building plan from the Sindh Building Control Authority (SBCA) before work starts. The approved plan is also the document every later approval rests on: the sale NOC, the occupancy certificate and the completion plan all check the building against it.
That makes the plan the foundation of the building layer. Our guide on how to verify property in Karachi explains that every Karachi property must clear land, building and title checks, and for owners who are building rather than buying, the SBCA plan is where the building layer begins.
This guide covers who needs an approved plan, how SBCA sorts applications into categories, the documents you need, the step-by-step process through the single window, realistic timelines, and the mistakes that cause plans to be refused or buildings to be sealed later.
Who needs an SBCA building plan
Section 6(1) of the Sindh Building Control Ordinance 1979 says no building may be constructed before SBCA has approved its plan and issued an NOC for construction. The word "construct" includes reconstruction, additions and alterations.
| Work | Needs SBCA plan approval? |
|---|---|
| New house on an empty plot | Yes |
| Adding a floor to an existing house | Yes |
| Demolishing and rebuilding | Yes, plus demolition permission |
| Flats, shops or offices for sale | Yes, plus a separate sale NOC |
| Changing a building's approved use | Yes, under section 6(3) |
| Building inside DHA or a cantonment | No; DHA or the board approves instead |
The Ordinance also sets professional requirements. Under section 7, plans must be prepared and signed by licensed professionals, and a licensed structural engineer must sign the structural design for buildings 16 metres or higher, or with five or more storeys above ground.
SBCA approval categories
SBCA sorts applications into five categories, and the category decides where your file goes.
| Category | Typical buildings | Processed at | Target |
|---|---|---|---|
| I | Residential plots up to 399 square yards under specified conditions, and bungalows above 399 square yards | Single-window facility, fully online | 15 days with complete documents |
| II and III | Larger or mixed residential and other buildings | District offices, moving online | As per regulations |
| IV | Public sale buildings, public-use and industrial buildings | SBCA one-window cell | As per regulations |
| V | Major town planning and land development projects | SBCA one-window cell | As per regulations |
Category I is where most homeowners fall. SBCA's director general said in late 2025 that the single window was issuing Category I approvals within 15 days, with a 99% success rate for complete applications.
Documents you need
For a typical Category I house, SBCA's single-window process has required documents such as these, attested by a licensed professional:
| Document | Purpose |
|---|---|
| Allotment order and possession order | Proves the plot was allotted and handed over |
| Acknowledgement of possession | Confirms physical possession |
| Lease deed | Proves leasehold title |
| Mutation or transfer order | Links the title to the current owner |
| Site plan | Fixes the plot's boundaries and dimensions |
| Forwarding letter from the land authority or lessor | Confirms title with KDA, MDA, the society or the Board of Revenue |
| Owner's or attorney's CNIC and photographs | Identity |
| Application forms (ZP-01 and ZP-02 undertaking) | SBCA's prescribed forms |
| Current site photographs | Shows the site's existing condition |
| Sets of architectural drawings | The plan itself |
| Demolition permission | Only if an old structure exists |
Section 6-A of the Ordinance also requires the applicant to disclose full and true information about title, any mortgage, lease or encumbrance, and all dues payable on the land. The land must be free of litigation.
Step-by-step: how the approval works
- Confirm title with the land authority. Get the forwarding or title confirmation letter from KDA, MDA, the society or the relevant authority.
- Appoint a licensed professional. Choose an SBCA-licensed architect or engineer, who prepares and attests the drawings and documents.
- Submit online. The professional files the application on SBCA's portal and uploads the documents, then delivers the hard copy to the single window.
- Pre-screening. SBCA checks the file for completeness. Incomplete applications are refused, and the applicant is notified by SMS or email.
- Pay fees. An online challan is issued for the application form and scrutiny fees.
- Scrutiny and approval. SBCA checks the plan against the Karachi Building and Town Planning Regulations 2002 and issues the approved plan and NOC to construct.
- Build to the plan. SBCA may inspect during construction.
- Report completion. Under section 7-E, completion must be reported within 30 days, followed by a final inspection, the occupancy certificate and the completion plan.
The Sindh Building Control Ordinance 1979 also sets an outer limit. Under section 7-D(3), an application not decided within 60 days of registration is deemed sanctioned to the extent it complies with the bye-laws and any master plan. That deemed approval never covers anything that breaks the regulations.
How timelines have changed
| Year | Change | Category I timeline |
|---|---|---|
| Before 2018 | Multi-stage process with several interdepartmental NOCs | About 60 days |
| 2018 | World Bank-backed reforms waive NOCs from the water board, EPA and Excise for Category I | 30 days |
| 2019 | Online single window; steps for permits and certification cut from 18 to 6 | 30 days |
| 2025 | Director general reports Category I approvals in 15 days | 15 days |
| February 2026 | Category I fully online; single windows extended to every SBCA region | 15 days |
| May 2026 | Backend processing automated for all permit types; integration with the Sindh Business One-Stop Shop | Faster tracking for all categories |
For builders, the larger categories still take longer, and public sale buildings need a sale NOC on top of plan approval.
Common reasons plans are refused or buildings sealed later
| Problem | What happens |
|---|---|
| Title not confirmed by the land authority | Application refused at pre-screening |
| Land under litigation | Application refused |
| Plan exceeds KBTPR limits for floors, setbacks or floor area | Plan refused or revised |
| Drawings not signed by licensed professionals | Application refused |
| Construction deviates from the approved plan | Sealing, demolition, no completion plan |
| False architect's certificate at completion | Action against the architect; deviating floors demolished |
The last two are the most costly. In a 2023 case, a builder with approval for basement, ground and one floor built ground plus three, and an architect certified that the building matched the plan. The Sindh High Court found the certificate false, ordered the extra floors demolished and referred the architect and engineer for action.
Building costs to plan for
Approval fees are only a small part of building costs. Construction itself is the main expense, and our breakdown of 10 marla double-storey house construction costs in Pakistan for 2026 gives a realistic budget for a typical family home. Budget for professional fees, SBCA challans, utility connection charges and the completion stage as well.
What the numbers show: Milkiyat.com findings
Category I approval time has fallen by three-quarters. From about 60 days before 2018 to a 15-day target: (60 − 15) ÷ 60 × 100 = 75% faster.
The single window cut two-thirds of the steps. From 18 steps to 6 for permits and certification: (18 − 6) ÷ 18 × 100 = about 67% fewer steps.
The statutory limit is four times the target. The Ordinance allows 60 days before a compliant application is deemed sanctioned. The single window targets 15: 60 ÷ 15 = 4 times faster than the legal maximum. Islamabad has moved in a different direction, as our guide to CDA's 2026 building approval rules shows.
One false certificate can cost half a building. In the 2023 case, 2 of the 4 above-basement levels as built were ordered demolished: 50% of the building above basement.

A. Category I residential plans are targeted at 15 days through the single window with complete documents. Larger categories take longer.
Q3. What documents are needed for SBCA approval?
A. Typically the allotment and possession orders, lease, mutation, site plan, land authority's forwarding letter, CNIC, SBCA forms, site photographs and drawings attested by a licensed professional.
Q4. Do I need SBCA approval to add a floor?
A. Yes. Additions and alterations count as construction under the Ordinance.
Q5. What if SBCA does not decide within 60 days?
A. Under section 7-D(3), the application is deemed sanctioned only to the extent it complies with the regulations and any master plan.
