in Kota Damansara

Local facts last reviewed 29 September 2026. Sources are listed at the end of the page.

Kota Damansara was launched in 1993 by PKNS, the Selangor state development corporation, and mixes bungalows, terrace and semi-detached houses with condominiums and apartments across numbered sections such as Section 9, 10 and 11 and Dataran Sunway. The N.39 Kota Damansara state seat recorded 177,765 residents in Census 2020, and two Kajang Line MRT stations — Kota Damansara and Surian — serve it.

MBPJ’s draft local plan describes Kota Damansara as a mixed growth centre at the north-western tip of Petaling Jaya, bounded by green hills, home to higher education and commerce, with access to the forest park; its visual identity is a linear transit town set against the forest reserve. The plan also commits to keeping and protecting the Kota Damansara forest reserve, so the green edge is not going anywhere — and neither is the run-off that comes off it.

Kota Damansara quick facts

Find the approved plan first, then choose the route

MBPJ’s plan-inspection form lets an owner obtain a copy of an approved building plan, the Certificate of Fitness (CF) or the Certificate of Completion and Compliance (CCC). The fees come from the Uniform Building By-Laws: RM50 when you apply for the file search, then, once the file is found, RM100 to inspect the approved plans and RM200 to copy them per set, and RM100 for each copy endorsed as a true copy. The owner supplies an application letter, proof of ownership, IC copies and the latest paid assessment and quit-rent receipts; someone applying for the owner needs the owner’s written consent.

With the approved plan in hand, MBPJ’s individual-house form (PB.B03) sorts your project into one of three applications: a new plan, an amendment to an approved plan (attach the original approval) or a re-approval (attach the original approved plan and the original payment receipt). The same form asks what kind of addition it is — front, side, rear, internal partitions or the whole house — and whether the house is a bungalow, semi-detached or terrace.

This matters in a PKNS township because an extension built in the 2000s may or may not match what is on file. If the earlier work was never approved, it is far better to know before an engineer designs a first floor on top of it.

Kota Damansara’s housing mix

• Terraces and semi-detached houses from the 1990s and 2000s: second-round kitchen and bathroom rebuilds, roofed yards, and first-floor rooms over the porch. Old concealed plumbing and wet-area membranes are the usual hidden items at this age.
• Bungalow lots: larger additions and rebuilds on individual plans, with slopes and retaining walls on some streets near the hills.
• Apartments, flats and condominiums, including the PPR Kota Damansara public housing that MBPJ’s draft plan lists as a candidate for urban renewal: interior work under the management body’s rules, and in older blocks, leaks through floor slabs from the unit above.

The draft plan counts four colleges or universities and three international schools in the Kota Damansara zone, so some units here are let to students and staff. If yours is a rental, hard-wearing choices pay back: tiles rather than laminate in wet zones, moisture-resistant kitchen carcasses, and fittings that are easy to replace between tenancies.

Forest-edge run-off and the Surian corridor

No Kota Damansara location appears in the JPS flood records for MBPJ from 2016 to 2022 reproduced in the draft local plan, which is reassuring for houses. Roads in north PJ are another matter in a downpour: on 12 November 2024, for example, a flash flood trapped five vehicles on Persiaran Surian Damansara in Taman Pelangi Damansara before the water receded. Heavy rain off the hills concentrates quickly on low roads.

For houses backing onto slopes or the forest edge, the renovation checklist is drainage-first: clear the yard and perimeter drains, make sure roof water is taken to a drain rather than dumped onto the slope, and have cracked retaining walls looked at before paving over the garden. Inside, uphill walls that stay damp are worth waterproofing from the outside where you can reach them.

Useful guides for Kota Damansara owners

We have not written a Kota Damansara-specific guide yet; these national guides cover the typical work:

• Unapproved extensions — what happens when an earlier addition was never approved.
• Hidden defects in a bought house — what to check when you buy an older PKNS-era home.
• Apartment and flat waterproofing — slab leaks in older blocks.
• Damp walls and mould — uphill walls and shaded rooms near the forest edge.
• Retaining wall costs — garden and boundary walls on sloping lots.
