Almost every building approval in Karachi outside the cantonments rests on one document: the Karachi Building and Town Planning Regulations 2002, usually called KBTPR. It decides how a building is categorised, who must design it, how long SBCA has to approve it, when a deviation can be regularised and when it cannot, and which buildings need permission before units are sold. Buyers rarely read it, but nearly every problem they meet with an illegal floor, a missing completion plan or an unapproved flat project traces back to a KBTPR rule that was broken.
KBTPR is the rulebook of the building layer. Our guide on how to verify property in Karachi explains that every building needs an approved plan and a completion record, and KBTPR is what defines both.
This guide explains what KBTPR covers, how it categorises buildings, the approval timelines it sets, its rules on deviations and regularisation, the main amendments since 2002, and what all of this means for someone buying a house, flat or shop in Karachi.
KBTPR at a glance
| Item | Detail |
|---|---|
| Full name | Karachi Building and Town Planning Regulations 2002 |
| Notified | 4 April 2002 |
| Legal basis | Section 21-A of the Sindh Building Control Ordinance 1979 |
| Applies to | Karachi, except cantonment areas and federal national-security projects |
| Replaced | The 1979 regulations |
| Enforced by | Sindh Building Control Authority |
| Chapters | 25, from jurisdiction and definitions to parking and zoning |
The official text of the Karachi Building and Town Planning Regulations 2002 sets out these chapters, starting with jurisdiction, definitions, permits and the licensing of professionals.
What the 25 chapters cover
| Chapters | Subject |
|---|---|
| 1 to 4 | Jurisdiction, definitions, permits and procedures, licensing of professionals |
| 5 | Public sale projects, including NOCs to sell units |
| 6 to 8 | Violations of land development, dangerous buildings, safety and security |
| 9 to 13 | Space, lighting and ventilation, structural design, water and sanitation, fire resistance |
| 15 to 18 | Heritage buildings, road widening, land development, subdivision, amalgamation and change of land use |
| 19 to 25 | Land use classification, bulk and spatial standards, roads, industrial areas, coastline, parking, zoning |
Key definitions buyers should know
| Term | Meaning under KBTPR |
|---|---|
| Floor area ratio (FAR) | Total floor area of a building divided by plot area |
| Footprint | Plot area covered by the building at any level, excluding basements |
| Compulsory open space (COS) | Part of the plot that must stay open to the sky, with listed exceptions |
| Height | Measured from the highest point of the road crown at the plot's front to the highest point of the building |
| Plinth | Finished ground floor level, capped at 4 feet 6 inches in most cases |
| Loft | Storage slab with internal access, up to 5 feet clear height and 30% of the room's area |
| Apartment building | More than one storey and more than two apartments sharing access |
These definitions matter when a seller claims a room or floor is "allowed". A loft used as a room, or a covered COS, is a violation, not extra space.
How KBTPR categorises buildings
| Category | Buildings covered | Approval |
|---|---|---|
| I | Bungalows on plots up to 120 sq yd; other buildings on such plots up to 33 feet | One stage; building designer, architect or engineer |
| II | All other bungalows; buildings up to 20,000 sq ft of floor area and/or 50 feet | One stage; architect and/or structural engineer, both for bungalows over 400 sq yd |
| III | Buildings over 20,000 sq ft and/or 50 feet | Two stages; architectural approval, then structural vetting |
| IV | Public buildings over 3,600 sq ft, essential facilities and public sale buildings | Two stages; structural design vetted by a proof engineer |
| V | Land development of 2.5 acres or more | One stage; town planner |
A proof engineer must vet buildings above ground plus four floors or 50 feet, or with more than 100,000 square feet of floor area. Every flat project sold to the public falls in Category IV, the strictest category.
Plot categories added in 2002
An October 2002 amendment set residential plot categories:
| Category | Plot size |
|---|---|
| LSA | Minimum 60 sq yd |
| L | Minimum 80 sq yd |
| R | 81 to 120 sq yd |
| A | 121 to 240 sq yd |
| B | 241 to 400 sq yd |
| C | 401 to 600 sq yd |
The same amendment cut the minimum size for subdividing a plot from 400 to 300 square yards, required every subdivided plot to have direct access of at least 12 feet, and limited amenity plots to ground plus two floors, or ground plus four for humanitarian use with a lift.
Approval timelines
| Step | Time limit |
|---|---|
| SBCA decision on a plan | 60 calendar days |
| Objections to an application | Within 30 days |
| No decision in 60 days | Deemed sanctioned to the extent it complies; work must start within one year, except Categories III and IV |
| Plinth or foundation verification | Work pauses 15 days after notice |
| Completion notice and plan | Within one month of completion |
| SBCA inspection after completion notice | Within 20 days |
| First appeal decision | 15 days |
| Public objection period, where required | 30 days, hearing within 5 days |
Our guide to the SBCA building plan approval process walks through the documents behind each step.
Deviations and regularisation
| Rule | What it means |
|---|---|
| Private residential deviations | Can be regularised during construction on payment of a composition fee |
| Public sale buildings | No internal layout deviations allowed during construction |
| Excess construction | Owner can be made to pull down the portion beyond limits |
| Regularisation barred, 2004 amendment | Environmental hazards, parking violations, reservations and road widening, COS deviation over 30%, and exceeding maximum height or storeys |
| 1979-approved buildings | Cannot be reconsidered for extra floors under the 2002 regulations |
| Extra-floor fee in the 2004 amnesty | Rs50 per square foot |
The barred list is the part buyers most need. An extra floor above the permitted height, or a building that covered its open space by more than 30%, cannot be regularised however much is paid.
Public sale projects
Chapter 5 requires a no-objection certificate from SBCA before units are sold in any building with three or more units transferred in parts, such as flats sold on sub-lease. Public sale buildings also cannot change internal layouts during construction, which protects buyers from units being redrawn after booking.
Licensing of builders and professionals
| Item | Rule |
|---|---|
| Builder registration fee | Rs30,000; renewal at 20% |
| Professional registration | Rs500; renewal Rs250 |
| Change of professional | Must be reported within 15 days |
| Licence violations | Suspension for six months, then one year, then cancellation on the third violation |
Amendments and disputes since 2002
| Year | Change |
|---|---|
| October 2002 | Plot categories, subdivision minimum, amenity plot floors, commercial land-use changes at Rs1,000 per sq yd, amalgamation up to four times the larger plot |
| September 2004 | Regularisation rules and a one-year amnesty, with limits on what can be regularised |
| March 2025 | SBCA amended definitions of amenity, commercial and residential uses and added "recreation uses"; residents challenged it in the Sindh High Court, and the amendment allowing commercial use was withdrawn on 13 May 2025 |
| February 2026 | Sindh High Court ordered building rules under section 21 of the Ordinance within 90 days, consistent with KSDP-2020, and consistency between KBTPR and the Regional Building Regulations 2018 |
KBTPR has been amended many times, and SBCA's own amendment notices should be checked for the version that applied when a building was approved.
What KBTPR means for buyers
| You are buying | KBTPR check |
|---|---|
| A flat off-plan | Category IV approval and the Chapter 5 NOC for sale |
| A finished flat | Completion plan, and floors within the approved plan |
| A house with extra floors | Whether the floors fall within limits that can be regularised |
| A portion on a residential plot | Whether the building became an apartment building without approval |
| A subdivided plot | At least 300 sq yd and 12-foot access, per the 2002 amendment |
| A building on an amenity plot | Ground plus two limit, and amenity use |
The completion record is where all these checks end. Our guide on why no unit should be registered without an SBCA completion certificate explains why.
What the numbers show: Milkiyat.com findings
SBCA has 60 days to decide, and objections must come in half that time. 60 days for a decision; 30 days for objections.
The 2002 amendment cut the minimum subdivided plot by a quarter. From 400 to 300 square yards: 100 ÷ 400 = 25% smaller.
A 30% COS breach is the regularisation cut-off. On a plot with 1,000 square feet of required open space, covering more than 300 square feet of it cannot be regularised.
An extra floor of 1,000 sq ft cost Rs50,000 to regularise in the 2004 amnesty. 1,000 × Rs50 = Rs50,000, where regularisation was allowed at all.
KBTPR is more than 24 years old. From April 2002 to October 2026: about 24 years and 6 months, with many amendments since.
Frequently asked questions

This guide is for general information. KBTPR has been amended many times and its zoning tables vary by area, so buyers should confirm the regulations that apply to any plot with SBCA and a qualified architect or lawyer before relying on them.
