In Singapore, “URA minor works” refers to development and building works that the Urban Redevelopment Authority (URA) has placed on its planning permission exemption list, so that no planning application is needed. The classification applies to planning control only. It does not exempt a project from structural approval by the Building and Construction Authority (BCA), from fire safety requirements administered by the Singapore Civil Defence Force (SCDF), or from the conditions that apply to a specific site. A works scope is therefore minor for URA purposes only when it appears on the exemption list and the property is not in an excluded category.
This guide is written for property developers, building owners, contractors and investors who must decide whether a scope of works can proceed without a URA submission, and what else must be cleared before work starts.
TL;DR
- URA publishes a Planning Permission Exemption List for minor development and building works. Buildings that are conservation buildings or national monuments, and sites in conservation, envelope control, central, urban design or other planning study areas, are outside its general scope.
- URA exemption does not waive BCA or SCDF requirements. Each agency classifies “minor” by its own criteria.
- BCA treats only works in its schedule of insignificant building works as free of plan submission, and advises owners to appoint a Qualified Person (QP) to confirm the classification.
- SCDF allows qualifying minor additions and alterations to be lodged rather than approved, at a fee of $90 per lodgement, under defined conditions.
- Confirm the classification in writing before mobilization, because misclassified works can delay the Certificate of Statutory Completion (CSC) and expose the owner to enforcement.

What URA means by minor works
URA regulates the use of land and the form of development: land use, building height, setbacks, site coverage and plot ratio. Its planning permission guidelines state that planning permission is required for development, and direct owners to check whether a proposal is exempt before applying.
The exemption is expressed as a list rather than a definition. The URA exemption page groups exempt items into categories, which include:
- Streets and access roads
- Works or structures for temporary use
- Perimeter fences, boundary walls and similar elements
- Site layout
- Exterior of a building
- Interior of a building
Each category is published as a separate schedule with its own conditions. As an illustration, URA’s exemption for perimeter fences and gates depends on a height limit of 1.8 m, on standard materials, and on the structure not obstructing vehicular sightlines. A fence at 2.0 m, or one that interferes with a sightline, falls outside the exemption even though it is visually the same type of work.
The practical consequence is that “minor” is not a judgment of size, cost or duration. A low-cost modification can require planning permission, and a larger internal fit-out can be exempt, depending on the schedule that applies.
Where the URA exemption does not apply
The exemption list does not cover development relating to the use of land or buildings, and it does not apply to certain categories of property. URA states that the list excludes gazetted national monuments and conservation buildings, and sites in conservation areas, envelope control areas, central areas, urban design areas, street block plan areas and other planning study areas where specific guidelines apply.
For owners of shophouses, buildings in the Central Area and landed houses under envelope control, this exclusion is often the controlling factor. A façade alteration that would be exempt on an industrial building in a general area can require formal clearance on a conservation shophouse. The first step in any assessment is therefore to establish the planning designation of the site, before examining the works themselves.
A change of use is a separate matter. Replacing a storage function with an office or retail function is a use question, not a building works question, and the exemption list does not resolve it. Developers considering a change of use should review the process described in our guide to URA planning permission for Singapore developers.
A URA exemption does not waive BCA or SCDF requirements
The most frequent error in minor works planning is to treat one agency’s exemption as general permission. Clearance in Singapore is agency-specific:
| Agency | Concern | Typical trigger for submission |
|---|---|---|
| URA | Land use, bulk, form, streetscape | Works or use not on the exemption list, or site in an excluded area |
| BCA | Structural safety, building control | Works that are not insignificant building works under the Building Control Regulations |
| SCDF | Fire safety | Fire safety works not qualifying under Regulation 4(4) of the Fire Safety (Building and Pipeline Fire Safety) Regulations |
URA’s own circular on car porch roofs in landed housing shows the principle. The guidelines on car porch roofs permit single-storey, unenclosed car porches within the front setback under defined conditions, but the structure must still be verified by a Professional Engineer or Registered Architect for structural adequacy, and a separate BCA structural approval may be required. Planning exemption addresses the form of the structure, not its safety.
BCA: insignificant building works and the role of the Qualified Person
BCA uses the term “insignificant building works” for works that do not require plan submission. According to the BCA guidance on building works not requiring approval, these works are listed in the First Schedule of Insignificant Building Works, and private property owners are advised to appoint a QP, being a Registered Architect or Professional Engineer, to confirm whether intended works are within that schedule or require submission.
Three points deserve emphasis:
- The schedule is the authority. A contractor’s description of works as minor has no regulatory weight.
- Combined scopes change the result. Several individually insignificant items can, taken together, affect structure. The QP assesses the scope as a whole.
- Consequences arise at completion. Works that required approval but were carried out without it can delay the CSC and complicate subsequent transactions.
BCA fee schedules also illustrate how differently the agencies treat scale. According to the BCA plan fee schedule, addition and alteration works are charged per storey, with a lower rate where no structural plan submission is made and a higher range where structural plans are submitted. A scope that a contractor regards as minor in labor terms can still be a structural submission for BCA. Owners reviewing the process in detail can consult our guides to BCA submissions and BCA structural submissions.
Accessibility obligations on A&A works
Where addition and alteration works are carried out to an existing building, additional accessibility obligations can arise. The BCA basic accessibility legislation records that the Building Control Act was amended in March 2020 to require owners of existing buildings undergoing A&A works to put in place basic accessibility provisions. Owners should confirm with their QP whether a proposed scope engages this requirement.
SCDF: minor additions and alterations
Fire safety is regulated separately. Under the Fire Safety Act 1993, a person intending to carry out fire safety works must first obtain approval of plans from SCDF, as described on the SCDF plan approval page.
A narrower pathway exists for qualifying works. The SCDF page on minor addition and alteration works sets out a lodgement scheme limited to the minor alterations or additions in the schedule to Regulation 4(4), with a fee of $90 per lodgement. The works must satisfy the conditions in the Regulation 4(4) schedule, which concern works within or in relation to an individual unit and, in substance, require that floor area is not increased, fire compartmentation is not affected and fire protection systems are not impaired.
Lodgement is not an absence of regulation. It is a notification process supported by layout plans, site plans and QP certification. Where a proposed scope touches sprinklers, fire alarm, fire-rated walls or means of escape, the lodgement route may not be available, and a full plan approval is needed. Our page on the Fire Safety Certificate explains the certification that follows completion.
How thresholds convert a minor renovation into a major one
Scale triggers differ by agency. BCA’s environmental sustainability requirements, for example, apply to existing buildings undergoing major additions and alterations above defined gross floor area thresholds, as set out in the BCA legislation on environmental sustainability. An owner who describes a retrofit as a minor renovation may find that the building is subject to a higher tier of requirements once the area or scope crosses a threshold.
The reasoning is consistent across all three agencies: the classification follows the published criteria, never the description given by the owner or contractor.
Examples of how the three agencies classify typical works
The following table is indicative and must be verified against the current schedules and the site designation before reliance.
| Scope | URA question | BCA question | SCDF question |
|---|---|---|---|
| Perimeter fence or gate | Within the height limit and conditions on the exemption list? | Structural adequacy if the structure is significant | Usually not engaged |
| Car porch roof, landed house | Within the car porch guidelines? | Structural verification and possible approval | Usually not engaged |
| Internal partition in a commercial unit | Interior of building schedule applies? | Is it within the insignificant works schedule? | Does it affect compartmentation or fire systems? |
| Mezzanine addition | Typically increases floor area, so exemption is unlikely | Structural plan submission | Fire safety implications |
| Façade alteration on a conservation building | Exemption list does not apply | Structural assessment | Depends on scope |
Mezzanine scopes in particular involve several agencies at once, and the sequence of submissions matters. Our guide to mezzanine authority submissions sets out the multi-agency position.
Related works that are often handled as minor
Repair scopes are commonly treated as minor, including roof, balcony and bathroom leak rectification. These are generally maintenance activities, but the repair method matters. Where the work involves removal of structural elements or alteration of drainage, the QP should confirm the classification first. For the repair itself, owners can refer to specialist waterproofing and leak repair works that are carried out after the structural question has been settled.
Demolition, even of a partial or non-structural element, has its own requirements. Owners considering removal of any building element should review the demolition permit requirements before mobilizing.
A verification procedure before works start
A disciplined sequence reduces the risk of misclassification:
- Establish the site designation. Determine whether the property is a conservation building, or lies in a conservation, envelope control, central or urban design area.
- Define the scope in writing. List every element, including dimensions, materials, locations and any change to floor area or use.
- Check the URA exemption schedule. Match each element to the relevant category and its conditions.
- Obtain a QP assessment for BCA. Request written confirmation that the scope is within the insignificant building works schedule, or that structural plans will be submitted.
- Assess SCDF position. Determine whether the scope affects fire compartmentation, fire protection systems or means of escape, and whether lodgement under Regulation 4(4) is available.
- Record the outcome. Retain the QP’s confirmation and any lodgement acknowledgments for the CSC and for future transactions.
Our guide, 5 steps to verify minor building works are exempt, covers this procedure in further detail. Where a scope is part of a wider renovation, the authority approvals for renovation guide addresses the combined position.
Our perspective
In our experience of statutory submissions, the exemption itself is rarely where projects go wrong. The difficulty is that owners and contractors read one agency’s exemption as a general clearance, and the other agencies are only considered when work is already under way. We therefore recommend that the classification question be answered once, in writing, by the QP, across URA, BCA and SCDF together, before a contractor is appointed.
We also recommend that the scope be fixed before the assessment. A scope that grows after the confirmation, for example by adding a mezzanine, a new opening in a structural wall or a change of use, invalidates the earlier conclusion. A short re-assessment at each scope change costs far less than a stop-work order, a delayed CSC or rectification of unapproved works.
Finally, we regard consistency of records as part of compliance. The written classification, the exemption schedule relied upon and the lodgement acknowledgments form the file that a purchaser, lender or incoming tenant may later request.

FAQ
Does a URA exemption mean I can start work immediately?
No. The exemption concerns planning permission only. BCA requirements for structural safety and SCDF requirements for fire safety are assessed separately, and a QP should confirm each before work begins.
Do conservation shophouses qualify for the URA exemption list?
Generally not. URA states that its exemption list does not apply to gazetted national monuments, conservation buildings, or sites in conservation areas and certain other designated areas. Formal clearance is required for such properties.
What is the SCDF lodgement fee for minor additions and alterations?
SCDF states a fee of $90 per lodgement for minor addition and alteration works that qualify under Regulation 4(4). Works that do not meet the conditions require plan approval instead.
Who decides whether works are insignificant for BCA?
The classification follows the First Schedule of Insignificant Building Works. BCA advises owners to appoint a QP, either a Registered Architect or a Professional Engineer, to assess whether the works fall within it or require plan submission.
