Power lines, pylons, substations and cemeteries near a home in Malaysia: what to check (2026)

中文 · Bahasa Melayu · Bahasa Indonesia

Some buyers will not look at a unit that faces a pylon or a cemetery; others do not mind at all. Neither view is wrong. The facts are these: TNB keeps a reserve of 20 to 35 metres on each side of a transmission line’s centre line, the Energy Commission says houses should not be built near high-voltage overhead lines, and the WHO has found the evidence linking power-line fields to illness not strong enough to be considered causal. Cemeteries and places of worship are a matter of personal and cultural preference. This guide covers what to check, calmly and in order.

Overhead power lines and pylon corridors

High-voltage transmission lines run on steel towers (pylons) along cleared corridors. In Malaysia these belong to TNB as the grid operator, and the land under them is a reserve, often called a wayleave or rentis.

Point	What the official sources say
Reserve width	TNB: 20 to 35 metres from the line’s centre line, on both sides (November 2021).
Building near lines	Energy Commission FAQ: permanent structures such as houses should not be built near high-voltage or extra-high-voltage overhead lines.
Working near conductors	Energy Commission FAQ: work or activity within 4.57 metres of a conductor needs valid permission from the owner or licensee.
Activities TNB warns against in reserves	Kite flying, drones, fishing, cranes and digging, open burning, storage, structures or plants taller than six feet, and sheltering under lines in storms.
Penalties	Under the Electricity Supply Act 1990, unauthorised activity near installations can mean a fine up to RM50,000 or up to two years’ jail or both; damage to installations up to RM100,000 or five years or both (as summarised by TNB).
New lines	The Energy Commission FAQ says licensees need the landowner’s permission before building transmission lines.

What it means for a buyer

• Landed homes: a back garden that runs into a reserve cannot be extended into it, and tall trees, flagpoles or structures there are a problem. If you are buying land to build on, ask your lawyer and architect whether a reserve affects the lot before you sign. My guide to buying land and building a house in Johor covers the other checks.
• Condos: a tower near a line will have been planned around the reserve. The question is mostly the view and your comfort, not use of the land.
• Title search: a land search shows registered interests on the title. Ask your lawyer to check whether anything affects the lot; see my guide to land title searches and caveats.
• Noise: some lines hum or crackle in humid or wet weather. Stand near them in the evening and listen.

Substations and telecom towers

Substations step voltage down for neighbourhoods. Small ones are common inside housing estates and condo car parks; large ones sit behind walls on their own land. What to look at is practical: hum from transformers, lighting, access for TNB vehicles, and whether a unit’s bedroom faces it. A condo’s site plan shows where the substation is; mark it against the unit you like.

Telecom towers and rooftop antennas are a different technology (radio frequency rather than power frequency). The WHO’s 2006 backgrounder said surveys found base-station exposures of about 0.002% to 2% of international guideline levels, and that there is no convincing scientific evidence that the weak signals from base stations cause adverse health effects. Malaysia’s communications regulator said in 2019 that tower emissions are below the international guideline limit, and reported that the Health Ministry agreed there is no scientific evidence of a hazard. In condos, rooftop antennas are usually a management decision; see my guide to checking condo management.

What the WHO and the Health Ministry say about health

I am a property agent, not a doctor, so I stick to what official bodies have published:

• Electric fields from power lines: the WHO’s 2007 review found no substantive health issues at the levels the public usually meets.
• Magnetic fields: in 2002 the WHO’s cancer agency classified them as possibly carcinogenic, based on studies of childhood leukaemia at higher average home exposures. The WHO’s 2007 review judged the evidence not strong enough to be considered causal, said such exposures are rare, and supported the existing international exposure limits.
• Base stations: the WHO found no convincing evidence of harm from their weak signals, and the Health Ministry’s view, as reported in 2019, was the same.

If you or a family member have a specific health concern, speak to your doctor. Many people simply prefer not to live next to a pylon, and that is a fair personal choice.

Resale and buyer perception

I have not seen official data that measures how much a nearby pylon, substation or cemetery changes prices in Johor, so I will not quote a figure. What I can say from practice is how it plays out:

• A smaller pool of buyers. Some buyers rule these units out, so a unit facing a pylon or cemetery may take longer to sell or rent. Others do not mind at all.
• It depends on the view. A unit that looks straight at a pylon or graves is treated differently from one in the same project facing the pool.
• Valuation. Valuers consider location factors when they value for a loan. If you are worried, ask the bank’s valuer early; see my guide on a bank valuation lower than the price.
• Choose the stack. In a large condo, the difference is often between stacks, not projects. My guide to choosing a condo unit’s facing and noise covers this, and high floor vs low floor covers views.

Cemeteries, columbaria and places of worship

Malaysia is multi-faith, and Muslim, Chinese, Hindu and Christian burial grounds and columbaria sit within many towns, alongside mosques, surau, temples and churches. How buyers feel about living near them varies by culture, faith and family.

• Feng shui and custom. Some Chinese buyers avoid units that look onto graves; others do not mind. My feng shui guide for JB homes explains common views. Treat it as preference, not fact.
• Festivals and visiting days. Cemeteries can be busy at certain times of year, such as Qing Ming, with traffic and parking on nearby roads. Places of worship have prayer times and festivals. Many residents value being close to them.
• Be respectful when you visit. Look from the road or the unit, not by walking through the grounds.

If being near a place of worship is a plus for you, say so. It is just as valid a preference as avoiding one.

Other neighbours to check: smell, noise and traffic

Nearby use	What to check	Where to ask
Sewage treatment plant	Smell, especially in the evening and after rain; whether the plant is enclosed	The national sewerage regulator (SPAN) and the operator for complaints; the management office
Highway or flyover	Traffic noise by day and night, dust; which stacks face it	DOE’s 2019 noise guidelines suggest 60 dBA by day and 55 dBA at night for low-density homes in built-up areas, and 65/60 for suburban and urban homes
Factories and industrial areas	Smell, noise, lorries, operating hours	The Department of Environment (Jabatan Alam Sekitar) and the council
Petrol stations, food courts, markets	Noise, smell, late-night activity, parking	Visit at night and at weekends
Rivers and low ground	Flood history and drainage	See my flood risk guide
Slopes and retaining walls	Cracks, drainage, maintenance	See my hillside homes guide

Noise inside a building is a separate question; see my guide to noisy neighbours in condos.

How to check a site before you commit

1. Satellite and street view. Look at least one kilometre around the project for pylons, substations, cemeteries, treatment plants, highways and factories. Line corridors show up as straight cleared strips.
2. Ask for the site plan. The developer’s site and stack plans show substations, refuse chambers, genset rooms and which units face which way. My show unit checklist lists what else to ask.
3. Check the local plan. Zoning in Johor is set by local plans prepared with PLANMalaysia@Johor. Its published list shows the Johor Bahru and Kulai district local plan (RTD Johor Bahru dan Kulai 2025, replacement plan) gazetted on 18 January 2018 and amended between 2020 and 2023. Empty land next door may be zoned for industry, utilities or a road; ask PLANMalaysia@Johor or the council’s planning department about specific lots.
4. Visit at different times. Morning peak, evening and a weekend night. Smell and noise change with wind and traffic.
5. Ask the occupants. In a subsale, ask the owner or tenant what they notice. My subsale inspection checklist covers the rest.
6. Use the map. My JB property map helps you compare locations before you shortlist.

Where to buy if this matters to you

Every part of Johor Bahru has some pylons, substations, cemeteries and main roads, so the answer is usually a careful choice of project and stack rather than of area. These guides help you compare:

• Mount Austin: established neighbourhoods with many condo and landed options to compare.
• Tebrau, Setia Indah and Molek: mature housing areas near malls and highways.
• Iskandar Puteri: newer planned townships where site plans are easy to check.
• Permas Jaya and Senibong: east-side waterfront areas.
• Skudai, Tampoi and Kempas: older and newer estates side by side.
• Kulai and Senai: landed homes near the airport and industrial parks.

Frequently asked questions

How far should a house be from high-voltage power lines in Malaysia?

TNB says its transmission-line reserves extend 20 to 35 metres from the centre line on each side, and the Energy Commission says permanent structures such as houses should not be built near high-voltage overhead lines. Ask TNB about the reserve for a specific lot.

Is it safe to live near pylons or power lines?

The WHO’s 2007 review found no substantive health issues from power-line electric fields at normal public levels, and judged the evidence on magnetic fields and childhood leukaemia not strong enough to be considered causal. It supports international exposure limits. Speak to your doctor about any personal concern.

Are telecom towers near homes harmful?

The WHO found base-station exposures of about 0.002% to 2% of international guideline levels and no convincing evidence that their weak signals cause adverse health effects. Malaysia’s communications regulator reported in 2019 that the Health Ministry held the same view.

Does living near a cemetery affect property value?

There is no official Johor data I can quote. Some buyers avoid units facing graves for cultural or feng shui reasons, which can narrow the buyer pool, while others do not mind. Choosing a stack that faces away is often the practical answer.

How can I find out what will be built on empty land next to a home?

Check the zoning in the local plan with PLANMalaysia@Johor or the council’s planning department, look for development signboards, and ask the developer for the site plan. Much of Johor Bahru and Kulai falls under the gazetted RTD Johor Bahru dan Kulai 2025, as amended.

Who do I complain to about smell from a sewage plant or factory?

Start with the management office or operator, then the Department of Environment for industrial pollution and the sewerage regulator SPAN for sewage issues. Electricity installation issues can go to TNB and, if unresolved, the Energy Commission’s complaints portal.

Know what is around a unit before you view

Tell me the projects or addresses you are considering. Before you travel to view, I will tell you what is around each one, which stacks face the pylon, substation, cemetery or main road, and which face away. You can also book an appointment or a Zoom consultation if you are abroad.
