Change of Use
Converting a House or Shoplot for Business Use (2026)

What “change of use” means in law

In everyday speech a change of use sounds informal: the front room becomes a tuition class, the ground floor of a shoplot becomes a clinic, the house becomes an office. In planning law it is a defined event. The Town and Country Planning Act 1976 defines “development” to include “the making of any material change in the use of any land or building or any part thereof”, and section 19 says no person shall carry out any development unless planning permission has been granted. A change of use is therefore treated like building work, even if nobody lifts a hammer.

The Act also spells out cases that always count. Using a building originally constructed as a dwelling-house for other purposes is a material change in its use. So is increasing the number of units in a building beyond what was originally approved, using as a home a building not built for living in, and any use that is inconsistent with the development plan for the area.

Common conversions that count

Most of the conversions owners ask about fall into one of the Act's own examples. The table sets out the usual ones and why each needs a decision from the planning authority, not just a renovation permit.

Two of these have their own guides: the shophouse upper-floor residential conversion guide and the room rental conversion guide.

Peninsular states and Kuala Lumpur

The Town and Country Planning Act 1976 applies in Peninsular Malaysia. The Federal Territory of Kuala Lumpur has its own law, the Federal Territory (Planning) Act 1982, whose definition of development likewise includes “any change in the use of any land or building or any part thereof”. The wording differs slightly; the practical result is the same. Whether your property is in Petaling Jaya, Shah Alam or Cheras KL, the council that approves building plans is also the place to ask about a change of use.

Interior works and the limits of the exemption

Section 19 exempts some work from planning permission: maintenance, improvement or other alteration of a building that affects only the interior. The exemption has conditions, and a business conversion usually breaks at least one of them. The interior work must not:

• involve any change in the use of the building or its land;
• materially affect the external appearance of the building;
• increase the height or floor area of the building;
• affect, or be likely to affect, the drainage, sanitary arrangements or soundness of the building; or
• be inconsistent with the local plan.

A new shopfront, a signboard on the facade, extra toilets, a grease trap or a mezzanine each touches one of these. Even a purely interior fit-out is not exempt if the reason for it is a new use. That is why “it is only interior work” is not a safe answer for a conversion.

Check the approved use before you sign or buy

The approved use of a building is recorded in its approved building plan, and the land use in the title and the local plan. Before signing a lease or buying a unit for a business, ask the landlord or seller for the approved plan, check what the title says the land may be used for, and ask the council if anything is unclear. Do not rely on what the last tenant did; an unapproved use does not become approved by being repeated.

Strata buildings add a layer. The management corporation's by-laws and the master title may restrict business use inside a residential parcel, whatever the council decides. The HMO and co-living guide explains how by-laws and council rules overlap.

The approval route, step by step

1. Confirm the current approved use from the approved building plan and the title.
2. Check the local plan zoning for the area; a use the plan does not allow is hard to approve.
3. Appoint an architect or draughtsman to prepare the planning application and, where works are involved, building plans.
4. Submit to the council and wait for the planning decision before starting work or trading.
5. Apply for the building plan approval and any other approvals the new use triggers.
6. Carry out the fit-out to the approved drawings, then apply for the business premises licence.

The commercial renovation permit guide sets out the approvals a commercial premises typically needs once its use is settled: council building approval, Bomba fire-safety sign-off, a business premise licence and a signboard licence.

What the new use changes inside the building

A new use usually brings new building requirements, and those drive the renovation budget more than the planning fee does. Typical knock-on items:

• Fire safety: escape routes, fire-rated separation between different uses, extinguishers and emergency lighting.
• Toilets and access: more users, staff and customer toilets, and step-free entry for wheelchair users.
• Power: a shop, clinic or salon often needs far more electrical capacity than a house or small office.
• Water and drainage: extra sinks, wash points and, for food businesses, a grease trap.
• Signage and the facade: a signboard licence and any change to the frontage.

The fire safety equipment guide and the accessible toilet and ramp guide cover two of the most common gaps.

What happens if you skip it

Under section 26 of the 1976 Act, using a building in breach of the local plan, or carrying out development without planning permission, is an offence punishable by a fine of up to five hundred thousand ringgit or imprisonment of up to two years or both, with a further daily fine for a continuing offence. The owner of the land is deemed to have permitted the act unless the contrary is proved, so a landlord cannot assume the risk sits only with the tenant.

Building work without approval is a separate exposure: ClickBina's shophouse guide notes that under the Street, Drainage and Building Act, building or altering without approval can bring a fine of up to RM10,000, and the council can order the work removed. The renovating without a permit guide explains how councils enforce and how unapproved work is regularised.

What the conversion works cost

Planning and building plan fees depend on the council and the floor area. These published ClickBina figures cover the items a conversion usually involves (indicative 2026, Klang Valley):

The ground-floor shoplot renovation guide prices a full shop conversion from bare unit to opening day.
