Neighbour & Boundary Disputes
The house next door has been cut into rented rooms
When a landed terrace house is converted into a high-density partitioned rooming house, complaints about 'too many tenants' are routinely ignored. The legally actionable route targets unapproved structural alterations and fire safety violations under s.70 and s.72 of Act 133.

Start from the plan and the title
This post works through the complaint that gets acted on is about building and fire safety, not about the number of tenants Two documents decide most landed neighbour disputes: the land search, which shows the registered boundary, and the approved building plan held by the local authority. Neither is expensive to obtain.
Why complaining about tenant numbers gets ignored by municipal authorities
When a quiet landed terrace street is disrupted by a high-density cubicle house, residents instinctively approach municipal authorities with emotional grievances regarding population density. They report that ten university students or twelve factory workers are cohabiting, complaining of noisy motorcycles, parking squabbles, and domestic clutter. In administrative practice, these reports are routinely closed without inspection. Malaysian municipal bylaws do not contain broad administrative headcounts that permit enforcement officers to count adults sleeping inside a private landed residence. Complaining about 'too many tenants' frames the issue as a private lifestyle dispute, allowing councils to wash their hands of the matter.
The legally actionable hook: unapproved structural partitioning under s.70 of Act 133
The moment you pivot from occupancy headcounts to structural building legality, the legal framework swings entirely into your favour. Under section 70(1) of the Street, Drainage and Building Act 1974 (Act 133), no person shall erect any building without prior written permission from the local authority. By statutory definition, 'erecting a building' includes making any alteration, addition, or internal structural partitioning that deviates from the building's originally approved layout plan. Constructing permanent gypsum board, autoclaved aerated concrete (AAC), or timber stud partitions to divide a family living room or master bedroom into tiny cubicles requires formal building plans submitted by a registered submitting person under section 70(2). Without municipal approval, every partition wall inside that house is an illegal structure.
State-adopted by-laws: natural light, ventilation, and lethal fire escape hazards
The second devastating statutory violation committed by cubicle rooming houses sits within the state-adopted Uniform Building By-Laws. The building by-laws rigidly enforce minimum public health and life-safety requirements for residential dwellings. First, every habitable bedroom must be provided with natural light and air through external windows having an aggregate opening area corresponding to a statutory minimum percentage of the room's floor area. Subdividing a house creates pitch-black, windowless interior cubicles with zero fresh air. Second, by-laws require wide, direct, fire-resistant escape corridors. When operators crowd corridors with partition doors and makeshift plywood walls, any electrical short circuit instantly turns the dwelling into a suffocating, lethal fire trap.
The municipal enforcement toolkit: s.72 demolition notices and s.70(11) mandatory court orders
Once a local council opens a formal building control investigation file, its statutory powers under Act 133 are decisive. Under section 72(1), the local authority serves a statutory notice directly upon the registered owner of the house, mandating the immediate cessation of illegal use and demanding the complete demolition and reinstatement of unauthorized internal partitions within a strict deadline. Under section 72(5), if the owner fails to dismantle the partitions, municipal enforcement teams possess the legal authority to enter the property, bring in demolition crews, tear down the drywalls, and recover all expenses from the property owner. Furthermore, the local council can prosecute the owner under s.70(11), where conviction attracts a fine not exceeding RM25,000 (confirm the current amount with your local authority) and the Magistrate is legally mandated to order the demolition of the unauthorized alterations.
Drafting an ironclad complaint that compels building inspectors and Bomba to raid
To achieve swift results, your complaint must be drafted like an engineering audit rather than a neighbourhood quarrel. Submit a formal written complaint letter addressed simultaneously to the Director of Building Control (Pengarah Kawalan Bangunan) of your municipal council and the state Fire and Rescue Department (Jabatan Bomba dan Penyelamat). Cite sections 70(1) and 72(1) of Act 133 and allege unauthorized structural alterations and acute fire code contraventions. Provide time-stamped photographs documenting renovation skips loaded with hacked masonry, deliveries of bulk drywall sheets, additional electrical sub-meters mounted on external walls, and multiple air-conditioning compressor brackets. When inspectors realize the property represents a catastrophic fire liability, inspection raids follow swiftly.
Check this against your own case
Start from the title and the approved plans, not from the argument. A land search shows the boundary as registered; the local authority holds the approved building plan. Most neighbour disputes on landed property are settled by those two documents, and the ones that are not need a lawyer rather than a louder conversation.
Buyer checklist
Across Malaysian urban centres, landed terrace houses in residential neighbourhoods are increasingly targeted by commercial subletting syndicates and irresponsible landlords who partition a single-family dwelling into eight, ten, or twelve tiny rented cubicles. Adjoining neighbours suffer immediate fallout: severe street parking congestion, overflowing garbage bins, continuous late-night noise, and severe plumbing overloads. Frustrated residents almost always lodge complaints framed around tenant headcount, asking the police or municipal council to intervene because 'there are too many people living next door.' That framing is a fatal mistake that leads nowhere. Neither municipal councils nor police forces possess a simplified statutory mandate to police domestic tenant headcounts in private landed homes. The complaint that actually compels municipal enforcement to act is structural and fire safety violations under the Street, Drainage and Building Act 1974 (Act 133). Erecting internal masonry, gypsum board, or plywood partition walls constitutes an unauthorized alteration under section 70(1) of Act 133. State-adopted Uniform Building By-Laws strictly mandate that every habitable room must have direct natural light and ventilation through windows opening directly into external air, and that escape corridors must maintain unobstructed fire-exit clearances. Subdivided cubicle homes almost invariably create windowless, suffocating interior rooms that represent severe fire traps. Under s.70(11), unauthorized alterations carry fines on conviction up to RM25,000 (confirm current amount with your local authority) and mandatory Magistrate demolition orders, while section 72 empowers the council to serve statutory demolition notices and enter the property under s.72(5) to tear down the illegal partitions. Crucially, enforcement under Act 133 runs against the registered property owner, not the transient master tenant.

Common questions
Can I report a neighbour's terrace house to the council simply because they rented to too many people?
Complaints based solely on tenant headcounts are usually ignored because councils lack simplified statutory occupancy policing powers for landed homes. Frame your complaint around unapproved internal partitioning and fire hazards under Act 133.
Does a landlord need local authority approval to build drywall partition rooms in a landed house?
Yes. Subdividing rooms is an alteration under s.70(1) of Act 133, requiring plans submitted by an architect or engineer under s.70(2) ensuring compliance with natural ventilation and fire escape standards in state-adopted by-laws.
What happens under Act 133 if a landlord creates illegal windowless cubicle rooms in a residential house?
Under s.70(11) of Act 133, unauthorized alterations carry a fine on conviction up to RM25,000 (confirm current amount with local authority) and mandatory court demolition orders. The council can also issue demolition notices under s.72(1).
Can the local council tear down the illegal partitions itself if the landlord refuses to comply?
Yes. Under section 72(5) of Act 133, if the property owner fails to comply with a section 72(1) demolition notice, the local authority may enter the building, demolish the partitions, and recover all costs from the registered owner.

Extending a landed house: the approval most owners skip
Extending a landed house without local authority approval violates s.70(1) of Act 133. An unapproved extension does not stay secret—it surfaces at the next bank valuation, mortgage inspection, and sale transaction, exposing the owner to statutory demolition orders.
Lewis Conclusion
Never treat municipal building approval as an optional formality you can skip to save time. Apply for proper building permits under s.70(1) and s.70(2) using a qualified submitting architect or engineer before carrying out extensions. Under s.70(11) of Act 133, unauthorised alterations carry a fine on conviction not exceeding RM25,000 (confirm the current amount with your local authority), and a Magistrate's Court shall issue a mandatory order to alter or demolish the building. Submitting plans upfront costs a fraction of the five-to-twenty times penalty fee under s.70(14) and protects your asset's marketability.
Your neighbour built without approval
When a neighbour builds an unapproved extension, complaining to the wrong forum wastes critical time. Understand how local authorities enforce building control breaches under s.72 of Act 133, why the Homebuyer Tribunal has zero jurisdiction, and how to file an actionable complaint.
Lewis Conclusion
When a neighbour begins unauthorized structural construction next door, act swiftly before concrete hardens. Submit a formal, dated written complaint with clear time-stamped photographs directly to your local council's building control department, citing unauthorized works under s.70 of Act 133. Do not waste time approaching the Homebuyer Tribunal, which has zero jurisdiction over neighbour disputes. If the unapproved work threatens structural damage to your shared wall or property, consult a civil litigation lawyer immediately to seek an emergency injunction in the civil courts while council building enforcement proceeds under s.72.
The wall between two terrace houses: who owns it, who may build on it
The dividing wall between terrace houses is governed by both registered cadastral boundaries and common-law rights of support. Neither neighbour may unilaterally hack, overload, or alter a party wall without qualified submissions under Act 133.
Lewis Conclusion
Never allow a neighbour or their contractor to hack into your shared dividing wall without inspecting an approved structural plan signed by a registered professional engineer. Conduct a land search to verify your exact cadastral boundary against the physical wall line. If a neighbour begins unauthorized demolition or structural loading of the party wall, lodge an urgent complaint with your local council's building control department citing s.70 of Act 133, and engage a litigation lawyer to serve a formal cease-and-desist letter before structural cracking occurs.
