Planning Permission, Enforcement & Building Control
Must-know for the exam
- Development includes a material change of use (Planning Act s 3(1)); shop (Class 1) to restaurant (Class 3) needs permission, a change within one use class does not.
- A licensing authority may not consider a licence for a use involving development until URA grants planning permission (Planning Act s 14(7)).
- Private homes need a minimum stay of 3 consecutive months; serviced apartments 7 days and SA2 3 months, both under one ownership with no strata subdivision.
- An enforcement notice may be served on the owner, the occupier and anyone responsible, and takes effect at least 14 days after service (Planning Act s 28).
- An enforcement notice is challenged only by appeal to the Minister before it takes effect; it is suspended meanwhile and the decision is final (ss 28(9), 29).
- Compliance does not discharge an enforcement notice; non-compliance risks a $200,000 fine or 12 months' jail (s 30), and default-works costs are a first charge on the land.
- An applicant may appeal a refusal or conditions to the Minister within 60 days of notification, and the Minister's decision is final (Planning Act s 22).
- Provisional Permission lapses after 6 months and Written Permission after 2 years; apply to extend 2 months before expiry, with up to 2 WP extensions before construction starts.
- Subdivision needs subdivision permission, one of three kinds of written permission; a lease of 7 years or less, options counted, is not a disposal (Planning Act s 4).
- Building works need BCA plan approval and a permit unless insignificant; a Qualified Person is a registered architect or engineer with a practising certificate; BCA issues TOP and CSC.

The Master Plan lesson covers what a site may hold. This one covers the permissions: when a change of use needs URA's written permission, how short stays and serviced apartments are controlled, what URA can do when someone develops without permission, and where BCA's building control takes over. Section B scenarios often turn on one of these steps, and a salesperson who markets an unauthorised use passes the problem to the buyer.
Change of use: when you need permission
Development includes any material change in the use of a building or land, so a change of use needs URA's written permission even when no works are done (Planning Act 1998 s 3(1), read on SSO 3 Oct 2026). The Act settles some cases outright (s 3(3)):
- Using one house as two or more separate houses.
- Using a building built as a dwelling house for other purposes, such as a hostel or an office.
- Using a dwelling house for dormitory accommodation, or for paid short-term stays where the same person occupies it for less than 3 consecutive months (s 3(3)(d) and Fourth Schedule).
- Running a building approved as one hotel, serviced apartment, boarding house, student hostel or workers' dormitory as separate entities (s 3(3)(j) and Second Schedule).
- Carrying on a use after a time-limited permission has lapsed (s 3(3)(k)).
Some things are not development (s 3(2)): works that do not materially affect the external appearance or floor area, using buildings or land within a house's curtilage for purposes incidental to enjoying the home, and a change between uses in the same use class.

Exam takeaway · remember this
URA decides use and intensity; BCA approves how it is built. Change of use needs permission even without works. Planning appeals go to the Minister.

Common questions
- Do I need URA approval to turn a shop into a café or restaurant?
- Yes. A shop and a restaurant are in different classes under the Planning (Use Classes) Rules, so the change is a material change of use and needs URA's written permission even if no building works are done. The food licence cannot be considered until that permission is granted (Planning Act 1998 s 14(7)). A change between two kinds of shop, within the same use class, needs no permission unless a site condition says otherwise.
- How do I appeal against a URA enforcement notice?
- Appeal to the Minister before the notice takes effect, which is at least 14 days after it is served (Planning Act 1998 ss 28(5), 29). While the appeal is pending the notice has no effect, and the Minister's decision is final. The notice's validity cannot be challenged in court any other way (s 28(9)).
- Can I rent out my condominium unit for short stays?
- No. Private homes must be let for at least 3 consecutive months. Paid stays shorter than that are unauthorised development under the Planning Act's Fourth Schedule, and URA takes enforcement action against them (URA, Short-Term Accommodation, updated 15 Jun 2026). Serviced apartments, with a 7-day minimum, and hotels are separate approved uses.
