Hacking Walls:
What's Allowed

General guidance for Klang Valley homeowners — not legal advice. Confirm specifics with your local council or management. Ask us on WhatsApp.

Opening up a kitchen or combining two rooms is one of the most popular and impactful renovation moves in Klang Valley homes. But not every wall can or should come down. Getting this wrong is dangerous, expensive to fix, and can compromise the safety of the entire building. Understand the wall types before any demolition commences.

Load-bearing vs partition walls

How to tell if a wall is load-bearing

• Check the building plans — the most reliable method. Structural walls, columns and beams are clearly marked on the structural drawings. For landed homes, the original architectural drawings held by the owner or council; for condos, the management holds the structural plans.
• Wall thickness — a standard half-brick partition is ~150mm (brick plus plaster). Load-bearing walls are often the same thickness but located at regular structural grid intervals. RC columns are typically 200–400mm square.
• Position and alignment — walls that sit directly above a wall on the floor below, or that align with beams on the ceiling, are more likely to be structural.
• Engage a Professional Engineer — if there is any doubt, a PE can examine the structure and confirm in writing before any hacking. A PE assessment costs RM 1,500–5,000 but is far cheaper than the consequences of hacking a structural element.

Wall type comparison for hacking decisions

Condo & strata approval

In a strata building you must get written management (JMB/MC) approval before removing even a non-structural partition wall. Structural walls, columns, beams and shear walls are strictly off-limits under any circumstances — they are part of the building structure, not your unit, and the management has an obligation to all owners to prevent structural damage.

Most condo managements also require a waterproofing certificate if any wet-area floor is disturbed during hacking, and a contractor registration form so they know who is on-site. See strata renovation rules → for the full approval process.

UBBL 1984 & building safety law

Altering structural elements without engineer-endorsed plans and council approval breaches the Uniform Building By-Laws 1984 (UBBL) and the Street, Drainage and Building Act 1974. Beyond the legal risk (stop-work order, reinstatement order, compound fine), removing a load path can cause cracking, progressive sagging or, in a worst case, partial collapse. It also voids your property insurance and creates serious problems when selling.

For landed homes, structural changes to an extension or upper-floor addition require council-approved drawings endorsed by a PE. Full details: do you need council approval? →

How much does wall hacking cost?

Indicative Klang Valley ranges — final cost depends on wall size, material, storey and debris disposal distance.

Safe hacking process

1. Identify the wall type by checking building plans or getting a PE assessment.
2. For condos: submit renovation form and obtain written JMB/MC approval.
3. For structural changes (landed home extension): prepare PE-stamped drawings and obtain council approval before any hacking.
4. Switch off and isolate any electrical circuits or plumbing pipes running through the wall before hacking.
5. Hack from top to bottom; support any lintel or floor above before removing the wall below.
6. Remove debris systematically — do not stack debris in stairwells or corridors (condo) or block the site access lane (landed).
7. Make good: patch, skim, prime and paint the floor, ceiling and adjacent walls where the old wall met them.

Open-plan conversions in Malaysia

The most popular hacking job in Klang Valley is opening up the kitchen to the dining area or removing the wall between the living and dining rooms. For most terrace houses, the wall between the kitchen and the interior dining area is a non-structural brick partition — it can be removed or a full-height opening created relatively cheaply (RM 3,000–8,000 including make-good). For double-storey homes, the wall between kitchen and dining on the ground floor may carry some load from the floor above — always check before hacking.

A half-wall or low partition wall → is a popular alternative that defines the spaces without structural risk, at lower cost than full removal.

Mistakes to avoid

• Assuming a wall is non-structural because it is made of brick — most structural walls in Malaysian homes are also built in brick or block. Brick construction does not mean non-structural.
• Not isolating services before hacking — electrical cables and plumbing pipes frequently run through walls. Hacking without isolating these first causes dangerous shorts and major water damage.
• Hacking in a condo without management approval — even removing a drywall partition triggers the management’s approval requirement; doing it without approval can result in stop-work orders and deposit forfeiture.
• Letting the contractor start before the PE confirms — verbal assurance that a wall is “just a partition” is not enough. Require the building plans to be checked before any hacking of a wall you are not certain about.
