Cantonment vs SBCA Jurisdiction: Whose Rules Apply to Your Plot

Two plots a few hundred metres apart in Karachi can be governed by completely different building rules. One may need SBCA's approved plan under the Karachi Building and Town Planning Regulations 2002. The other may answer only to a cantonment board and its own by-laws, with SBCA having no say at all. Buyers who do not know which side of that line their plot sits on often collect the wrong approvals, or none.

The line matters because Karachi's regulators were never designed as one system. Our guide on how to verify property in Karachi explains that DHA and the six cantonment boards run a federal track while most of the city runs a provincial one. This guide focuses on the practical question that follows: for one specific plot, whose rules apply, and what does that change for the buyer?

It covers how to find out which regime governs a plot, how the two rulebooks differ, where they overlap, and what to check in each case.

Two regimes, one city

The practical effect is simple: an approval issued under one regime carries no weight under the other. An SBCA plan for a cantonment plot, or a board approval for a plot outside cantonment limits, is not an approval at all.

The Sindh High Court has stated the boundary plainly. In a 2024 judgment in Suit No. 670 of 2024, it described KBTPR 2002, made under the Sindh Building Control Ordinance, as regulating building approvals across Sindh "excluding cantonments". Inside cantonment limits, KBTPR does not apply.

Step 1: find out which regime governs your plot

Neighbourhood names are unreliable. "Clifton" covers both cantonment land and KDA scheme land, and some roads have one regime on each side.

How to check:

1. Ask the seller for the land document. A cantonment board property record, a DHA transfer or an old-grant or leasehold record points to the cantonment regime. A KDA allotment, a society file or a Board of Revenue record usually points to SBCA.
2. Check the property tax bill. In cantonment areas, the board collects property tax under Sindh's 2024 amendment law. Elsewhere, Sindh Excise and Taxation does.
3. Check the utility and municipal bills. Water, sanitation and conservancy charges from a cantonment board indicate cantonment limits.
4. Ask the cantonment board directly whether the plot lies within its limits, and get the answer in writing.
5. Check for overlapping records. In parts of Clifton, KDA is the lessor while the Clifton Cantonment Board controls building approval.

Physical location still matters. A plot must be matched on the ground to its documents before it can be placed on the right side of a jurisdiction line, especially on roads where cantonment and scheme land meet.

Step 2: understand what each rulebook allows

Under SBCA, KBTPR 2002 sets floors, height, setbacks, floor area and parking by plot size, land use and road width. Buildings above 50 feet need NOCs from the relevant agencies, and structural designs for buildings of 16 metres or five storeys above ground must be signed by a licensed structural engineer.

Under a cantonment board, the board's own by-laws apply: for example, the Clifton Cantonment Board's Building Bye-Laws 2007 or the Karachi Cantonment Board's Building Bye-Laws 2023. Height is limited not only by the by-laws but by security clearance. In a 2024 Sindh High Court case concerning a plot in E.I. Lines, Saddar, the Karachi Cantonment Board had approved nine floors. Floors 10 to 17 were sent to the Station Headquarters for a security NOC, the Corps Headquarters declined it on security grounds, and construction was limited to the approved nine.

Inside DHA, DHA runs its own approval process: site plan, "A" lease, building plan approval, stage NOCs and a DHA completion certificate.

Where the two regimes overlap

Clifton and KDA leases. Many Clifton plots were leased by KDA but sit within the Clifton Cantonment Board's limits. In a 2021 case, Military Lands and Cantonments said a Clifton Block 9 plot fell under CBC's jurisdiction while KDA, as lessor, issued the land NOC. For such plots, buyers need KDA for the lease and CBC for building control.

Disputed boundaries. In April 2026, residents told the Sindh High Court that the Clifton Cantonment Board lacked valid federal notifications for DHA Phases 6, 7 and 8. CBC relied on SRO 207(I)/83. The court did not strike down its jurisdiction but ordered it to place complete gazette notifications on record and to refrain from levying municipal taxes in those areas without them. A plot in a disputed zone can face uncertainty about which body's charges apply, so confirm the exact location first, using the steps in our guide on how to verify a property's location before paying a token.

Suing the wrong body. Disputes with a cantonment board follow federal law. The Cantonments Act 1924 requires two months' written notice before a suit against a board, and courts have treated suits filed without that notice as incompetent. A buyer who treats a cantonment dispute like an SBCA matter can lose time before the case even starts.

Property tax. Sindh's 2024 amendment made provincial property tax chargeable in cantonment areas but left assessment and collection with the boards, which keep 2% as collection charges and pay 15% of the rest to the province.

Common buyer mistakes

What to check in each regime

Karachi is not alone in this. Lahore also splits building control between several bodies, and our comparison of three rulebooks in one city: the development authority, cantonment boards and TMAs in Lahore shows the same pattern. The checks below apply to Karachi.

What the numbers show: Milkiyat.com findings

One security decision cut a tower nearly in half. In the Saddar case, 9 floors were approved and floors 10 to 17 were refused. That is 8 of 17 planned floors, or about 47% of the building, outside its approval.

The 50-foot line comes early. At roughly 10 feet per floor, a building crosses 50 feet at about five storeys. Above that, an SBCA-area building needs agency NOCs, while a cantonment building may need a security NOC. Most mid-rise flat projects cross this line.

Every Rs100 of cantonment tax splits three ways. The board keeps Rs2 as collection charges. Of the remaining Rs98, 15% goes to Sindh: Rs98 × 15% = Rs14.70. The board keeps Rs83.30, about 85% of what it collects.

Frequently asked questions

Q1. Do SBCA rules apply in cantonment areas?

A. No. The Sindh High Court has described KBTPR 2002 as regulating building approvals in Sindh excluding cantonments. Cantonment boards and DHA apply their own rules.

Q2. How do I know if my plot is in a cantonment?

A. Check the land document, the property tax bill and municipal charges, and ask the cantonment board in writing whether the plot falls within its limits.

Q3. Is Clifton under SBCA or the cantonment board?

A. Much of Clifton falls under the Clifton Cantonment Board for building control, while KDA is often the lessor of the land. Confirm block by block.

Q4. What is a security NOC in a cantonment?

A. Clearance from the military station headquarters for taller buildings. Floors that need it are unapproved until it is issued.

Q5. Who collects property tax in cantonment areas?

A. The cantonment board, under Sindh's 2024 property tax amendment, which sends a share to the province.

Q6. Can I sue a cantonment board like SBCA?

A. Disputes follow the Cantonments Act 1924, which requires two months' written notice before a suit against a board.

Q7. Does DHA follow cantonment by-laws?

A. DHA runs its own building approval process for its phases, within the Clifton Cantonment Board's area.

This guide is for general information. Jurisdictions, by-laws and procedures change, and buyers should confirm which authority governs a plot, and every approval it needs, directly with SBCA, the relevant cantonment board, DHA, KDA where applicable and a qualified lawyer before paying.
