Defects, Repairs & Renovation
Which renovations need local authority approval, and which do not
Malaysian building law does not provide a single national list of exempt renovations. Under s.70(1) of Act 133, erecting any building without prior written permission is prohibited, with detailed rules governed by state-adopted by-laws and enforced strictly against the owner.

Settle this before work starts
This post works through a question with no single national answer, and the wrong assumption sits with the owner rather than the contractor Building control is enforced against whoever owns the building. Your contract with the contractor governs what you can recover from them afterwards; it does not move the notice off your name.
The statutory prohibition under s.70(1) of Act 133
The starting point for all renovation legality in Peninsular Malaysia is section 70(1) of the Street, Drainage and Building Act 1974 (Act 133), which explicitly establishes: 'No person shall erect any building without the prior written permission of the local authority.' In section 3, the statutory definition of erecting a building extends far beyond constructing a new dwelling from vacant ground. It encompasses any alteration or addition to an existing building, any structural modification that affects load distributions, and any change that encloses open spaces. This statutory prohibition is universal across Peninsular Malaysia, meaning that making physical alterations to an existing property without council consent is an offence by default unless explicitly exempted by law.
State-adopted by-laws and local authority discretion
A widespread mistake among property owners is searching for a single federal checklist of permitted home renovations. While Act 133 is the parent statute enacted by Parliament, detailed technical building regulations reside within the Uniform Building By-Laws as adopted by each individual state. Because each state legislature adopts and amends its own version of the building by-laws, specific requirements, setback distances, and application exemptions differ between Selangor, Penang, Johor, and the Federal Territories. Local authorities (such as Majlis Bandaraya Petaling Jaya, Dewan Bandaraya Kuala Lumpur, or Majlis Bandaraya Iskandar Puteri) publish distinct local renovation guidelines. Homeowners must check with their own local authority rather than assuming that rules in one municipality apply across state lines.
Permitted interior cosmetic works versus structural alterations
In daily municipal practice, local authorities draw a practical line between interior decorative fit-outs and structural alterations. Minor cosmetic works—such as installing built-in kitchen cabinets, fitting bedroom wardrobes, laying floor tiles over existing slabs without hacking structural screeds, repainting internal plaster, or upgrading sanitary ware within existing bathroom footprints—generally do not require formal building plan approval from the council. However, the moment renovation involves hacking brick walls, creating new window or door openings, constructing mezzanine floors, relocating staircases, or casting reinforced concrete tie-beams, the works alter the approved layout and structural loading of the building, triggering mandatory submission requirements.
External extensions, setbacks, and PSP submission under s.70(2)
External modifications that expand the physical footprint of a house always require formal building plan approval. Extending a ground-floor kitchen into the rear setback, constructing an enclosed laundry area in a side yard, converting an open balcony into an enclosed room, or building an extended concrete car porch slab alters the building's approved envelope. Under section 70(2) of Act 133, plans and specifications for these works must be formally prepared and submitted to the local authority by a principal submitting person (a registered architect) or a submitting person (a registered professional engineer). The plans must comply with statutory setback distances, natural light and ventilation requirements, and storm drainage provisions specified in the state-adopted building by-laws.
Statutory penalties under s.70(11) and the myth of contractor indemnity
Many homeowners proceed with unapproved extensions because their contractor claimed that 'nobody applies for kitchen extensions' or promised to handle any council queries. This assumption is disastrous. Under section 70(11) of Act 133, any person who makes an alteration to any building without prior written permission is liable on conviction to a fine not exceeding twenty-five thousand ringgit (confirm the current amount with your local authority), and a Magistrate's Court shall, on the application of the local authority, issue a mandatory order to alter or demolish the building. Building control notices are served strictly on the registered owner of the property. Private contract indemnity clauses cannot shield a homeowner from statutory prosecution or court-ordered demolition.
Check this against your own case
Confirm two things with your own local authority before work starts: whether the work needs approval, and whether your contractor is registered for it. Both answers differ between councils and states, and a renovation that needs approval and does not have it is the owner's problem, not the contractor's.
Buyer checklist
Under section 70(1) of the Street, Drainage and Building Act 1974 (Act 133), no person shall erect any building without the prior written permission of the local authority. The statutory definition of erecting includes structural alterations, additions, and building extensions. There is no single national checklist specifying which renovations are exempt; the detailed technical rules sit in the Uniform Building By-Laws as adopted by that state, and each individual local authority (Dewan Bandaraya, Majlis Bandaraya, or Majlis Perbandaran) enforces its own approval guidelines. As a general rule, purely internal non-structural works—such as installing built-in kitchen cabinets, interior repainting, or changing sanitary fixtures in existing bathrooms—do not require municipal building plan submissions. Conversely, knocking down walls, adding reinforced concrete columns or beams, extending kitchen footprints to the boundary, adding car porch awnings beyond permissible setbacks, and altering rooflines legally require plans submitted by a principal submitting person or submitting person under s.70(2). A contractor's casual verbal assurance that 'approval is not needed' provides zero legal protection to the owner.

Common questions
Does installing built-in kitchen cabinets or internal painting require local council approval in Malaysia?
Generally no. Purely internal cosmetic fit-outs—such as built-in wardrobes, kitchen cabinetry, interior repainting, and floor tiling that do not alter the building's structural load or external envelope—do not require formal building plan submissions under Act 133.
Can I extend my landed house kitchen all the way to the back boundary drain without a permit?
No. Extending a building footprint is legally classified as erecting a building under s.70(1) of Act 133. It requires building plans submitted by a registered architect or engineer complying with setback distances in the state-adopted Uniform Building By-Laws.
What is the legal penalty under Act 133 for carrying out unauthorised alterations to a house?
Under s.70(11) of Act 133, unauthorised alterations carry a fine on conviction not exceeding twenty-five thousand ringgit (confirm the current amount with your local authority), and a Magistrate's Court shall issue a mandatory order to alter or demolish the building.
If my contractor promised that a permit was unnecessary, can the council fine the contractor instead of me?
No. Statutory enforcement under Act 133 runs strictly against the registered owner of the property. The local authority issues notices and prosecutes the property owner; private contractual promises by a contractor provide no defense against statutory enforcement.

What counts as a defect, and what is just wear, settlement or your own doing
The legal boundary between an actionable construction defect, natural settlement, fair wear and tear, and owner damage decides who pays for repairs in Malaysia. In statutory HDA homes within the 24-month defect liability period, developers bear rectification duties, whereas subsale properties are sold strictly as-is.
Lewis Conclusion
Before raising a dispute with a developer or seller, classify the issue against the statutory contract. If your property is a new HDA home within the 24-month DLP, serve a formal written defect notice demanding rectification within 30 days. If the developer fails to respond or perform, file a claim up to RM50,000 at the Tribunal for Homebuyer Claims within 12 months from the expiry of the defect liability period. If you bought a subsale unit, remember that no statutory defect period exists, meaning pre-signing inspection is your only legal protection.
A landed house that leaks
Water leaks in a Malaysian landed house behave differently from strata inter-floor leaks. Rainwater tracks along trusses and beams before dripping into ceilings, making diagnosis tricky. In new HDA homes within the 24-month DLP, developers must repair within 30 days, while subsale buyers inherit the problem as-is.
Lewis Conclusion
Stop treating the water stain on your plasterboard ceiling and get an experienced inspector or roofer into the roof void during heavy rain to trace the structural path. If you are within the 24-month defect liability period on an HDA landed home, deliver a formal written notice under Schedule G demanding rectification within 30 days. If the developer fails to perform, file a claim up to RM50,000 at the Tribunal for Homebuyer Claims within 12 months from the expiry of the defect liability period. If it is a subsale house, budget for roof flashing and gutter remediation before signing the contract.
Cracks in your walls: which are cosmetic, which are structural
Cracks in a Malaysian home range from superficial plaster shrinkage to structural foundation settlement. The orientation, pattern, and whether cracks widen over time determine whether you call a painter or a professional engineer. For HDA homes within the 24-month DLP, developers must make good within 30 days.
Lewis Conclusion
Never let a contractor persuade you to simply plaster over a diagonal or stepped crack that continues across structural elements. If cracks are active or accompanied by jamming doors, commission a registered professional engineer to carry out a structural assessment. If your house is within the statutory 24-month defect liability period under Schedule G or Schedule H, deliver a formal written notice compelling the developer to rectify within 30 days. If the developer defaults, bring your claim up to RM50,000 to the Tribunal for Homebuyer Claims within 12 months from the expiry of the defect liability period.
