Condo Renovation Approvals: Floor Area, Appearance and Safety

A condo renovation quotation is not permission to start work. First establish whether the proposal increases floor area, changes the building’s appearance, affects its structure or falls within the statutory safety-equipment provision. These routes have different conditions, and an estate’s renovation form does not replace planning or building approval.

This guide concerns proposed work in a strata condo. HDB owners should use HDB’s renovation requirements, including its contractor and work-specific rules. For either property type, keep approval costs and possible delays in your renovation cash-flow budget.

Floor area and external appearance follow different routes

Under section 37(1) and (2) of the Building (Strata Management) Act 2004, an improvement for an owner’s benefit that increases, or is likely to increase, the floor area of the land and building in the strata title plan needs authority by a 90% resolution of the management corporation. Section 37(2A) preserves Planning Act requirements. Management approval alone cannot supply planning permission.

For other improvements affecting appearance, section 37(3) and (4) provide for management-corporation authority where the appearance and structural-integrity conditions are met, subject to the section 37A exception below. Do not apply the floor-area voting route indiscriminately to every renovation. Equally, describing a proposal as internal work does not settle what it changes.

Ask the architect or engineer advising on the proposal to identify the applicable statutory floor-area measure and the actual scope on drawings. Do not decide that enclosing an existing area adds no floor area simply because the space was already accessible. URA’s renovation guidance makes property type and the nature of the works relevant; an increase in gross floor area generally requires planning permission.

Safety equipment has a specific statutory exception

Section 37A permits defined safety equipment despite restrictions under the Act, its regulations or by-laws. Its categories include fall-prevention features, opening restrictors, animal or insect screens, intruder alarms or monitoring systems, and protective locks or security mechanisms. A blanket statement that every appearance-changing installation needs consent misses this provision.

The conditions still matter: installation must be competent and proper, its appearance must be in keeping with the building, and installation damage to common or limited common property must be repaired. The provision is not a general exemption for any balcony enclosure or proposed alteration. Match the actual equipment, fixing method and location to the statutory wording before ordering.

Send management the product specification and marked-up drawing, identifying why the equipment falls within section 37A. Ask for any practical access arrangements needed for the installation. If there is disagreement about whether the proposal qualifies, pause the disputed work and contact Lin Xuan or Ade for an introduction to a property lawyer. The agents can arrange the introduction; they do not determine the legal entitlement.

Keep estate, structural and planning decisions separate

A useful renovation file identifies each decision and the person responsible for obtaining it. For example, estate arrangements may concern contractor access and protection of common areas, while the qualified professional assesses statutory submissions. An acknowledgement that an application was received is different from authority for the specified work.

BCA explains that some minor works are exempt from plan submission, but other authority approvals and safety requirements can still apply. Ask a qualified professional about the proposed scope before relying on an exemption. Do not remove a wall or cut into a slab because the contractor calls it non-structural.

• Before paying a non-refundable order: have the proposed materials, dimensions, fixing details and approval dependencies written down.
• Before starting: check that the documents cover the selected unit and final design, rather than an earlier alternative.
• Before changing the design: ask whether the amended work requires a revised submission or decision. Keep the original and revised drawings together.

When buying a previously renovated condo

A resale buyer needs the history of existing work as well as a plan for future renovation. Section 37(4A) allows a management corporation’s written remedy notice to be addressed to the subsidiary proprietor whether or not that proprietor caused the contravention. An attractive finished interior therefore deserves document checks before the purchase becomes binding.

Request the relevant plans, permissions, correspondence and any outstanding notices. BCA recommends competent inspection against approved plans; a legal search only reveals unauthorised work already brought to BCA’s attention and does not guarantee that no unauthorised structure exists. A seller’s assurance and an inspection answer different questions.

If an alteration is unresolved, establish who will investigate, what reinstatement might involve, and how the purchase contract will address it. Do not treat an unpriced removal obligation as a cosmetic defect. Our resale defects guide helps compare the proposed discount with the work and disruption.

Set a start date only after the scope is settled

Ask for a written sequence covering permissions, access, deliveries, inspections and payment milestones. Work out where the household will stay if the start date moves. The better quote is the one you can fund and lawfully carry out, with a workable route to moving in.
