Housing Developers Rules in Singapore: What They Make a Developer Do, and What They Give a New-Launch Buyer
The rules behind every new launch, one by one: who needs a licence, what you must be told before you pay, the 5% to 10% booking fee, the three-week option, the fixed contract and payment schedule, and developers' ABSD deadline.
The Housing Developers Rules govern how a licensed developer sells private homes and ECs in a project of five or more units. The booking fee is 5% to 10% of the price, for an option in the prescribed form that runs 3 weeks from delivery of the title deeds and the agreement to sign; walk away and 75% is refunded. The sale and purchase agreement and its payment schedule are prescribed, changed only with the Controller of Housing's approval, and adverts must carry the developer's licence number.
When you buy a new launch in Singapore, most of the paperwork is not the developer's to write. The Housing Developers Rules, made under the Housing Developers (Control and Licensing) Act, prescribe the option to purchase, the sale and purchase agreement and the payment schedule, cap the booking fee, and set what the developer must tell you before it takes your money.
This guide goes through the Rules one by one, with what each means for you as a buyer and the sums at today's median new-launch price. The Rules and the Act are as read on Singapore Statutes Online, with URA's and IRAS's guidance, in September 2026.
What are the Housing Developers Rules?
They are the subsidiary rules under the Housing Developers (Control and Licensing) Act that govern how a licensed developer sells units in a housing project of five or more units: what adverts must show, the booking fee, the prescribed option and sale and purchase agreement, the payment schedule, and the developer's duties to buyers. In the year to 30 August 2026, 9,538 new homes in 102 projects were sold under them.
The Rules define a "housing project" as land being built on "with a view to building 5 or more separate units for use as residential dwellings" (rule 2), and they are enforced by URA's Controller of Housing. What each rule does for you:
| Rule | What it says | What it means for you |
|---|---|---|
| 3, 6, 7 | Adverts must show the developer's name and licence number, tenure and encumbrances, expected vacant possession and legal completion dates, and the location; nothing false or misleading | You can check the developer and the dates before you visit |
| 8 | Booking fee "not less than 5% but not more than 10% of the purchase price" | A capped first payment |
| 10 | The option must be in Form 2, granted on payment of the booking fee, after you receive the Form 3 information | A standard option, and the facts first |
| 11 | One option per unit at a time, valid 3 weeks from delivery of the title deeds and the execution copies of the agreement | Time to read and decide, with no one else able to book your unit |
| 12 | The sale and purchase agreement must be in Form 4 or Form 5; changes need the Controller's approval, and unapproved ones are "null and void" | A contract the developer cannot quietly rewrite: any approved changes sit in a schedule you can read |
| 15 | No waiver of your rights without the Controller's consent | Side letters giving up your rights do not bind you unless the Controller consented |
| 17 | A plan of your unit attached to the agreement, detailed enough to lodge a caveat | You can protect your purchase on the title |
| 18 | Licence fees by project size | Paid by the developer, not you |
Every rule is on Singapore Statutes Online, current version as at 25 September 2026.
On a new launch, the law writes the contract; any change to it needs the Controller's approval, and you can read it.
Who needs a housing developer licence in Singapore?
Anyone who develops, or finances the development or purchase of, more than four units of housing accommodation. The Act says no such housing development may be carried out except by a developer with a written licence from the Controller of Housing. URA issues a sale licence, which allows building and selling, and a no-sale licence, which allows building only.
The Act defines "housing development" as the business of developing, or providing the money for developing or buying, "more than 4 units of housing accommodation", and section 4(1) is blunt: "No housing development may be carried out or undertaken in Singapore except by a housing developer who or which is in possession of a written licence from the Controller authorising it to do so" (Act). Banks and insurers that only lend are excluded.
URA explains the two licences: "(i) a sale licence which allows you to commence construction works and sale of units after obtaining approval from all relevant authorities, including building plan approval and (ii) a no-sale licence which allows you to commence construction works only after obtaining approval from all relevant authorities" (URA).
The licence fee rises with the project (rule 18):
| Units in the project | Licence fee |
|---|---|
| Not more than 10 | $2,500 |
| 11 to 50 | $8,000 |
| 51 to 100 | $18,000 |
| 101 to 200 | $30,000 |
| 201 to 400 | $45,000 |
| More than 400 | $65,000 |
URA applies this project by project: "If you are developing a housing project with more than four units, you will have to comply with the Housing Developers (Control and Licensing) Act and its Rules" (URA).
Five units makes a housing project; a housing project needs a licensed developer.
What must a developer give you before you pay the booking fee?
The prescribed information on the unit and the project (Form 3), a notice of the documents the developer needs for its anti-money-laundering checks, and, for a condominium unit, the schedule of strata units and any plan of limited common property for you to inspect. You sign an acknowledgement that you received them.
Rule 10(4): the developer "shall, before accepting a booking fee from an intending purchaser for an option to purchase a unit in a housing project — (a) provide the intending purchaser with the particulars, documents and information relating to the unit and the housing project as described in … Form 3", give notice of the documents it needs "to perform the customer due diligence measures", and "(b) obtain written acknowledgment from the intending purchaser" (Rules). Rule 10(5) adds, for a strata unit, "a copy of the schedule of strata units" and any plan of limited common property.
URA's guidance for buyers says the same in plain words: "The developer is required to provide you with a set of mandatory information on the housing project and unit before accepting the booking fee from you" (URA).
Check the developer's licence too, on URA's licence check: it "allows you to check if a developer holds a valid housing developer's licence" (URA).
Read the Form 3 pack before you pay: the acknowledgement you sign confirms the developer handed it over.
How much is the booking fee for a new launch, and what does it buy you?
Between 5% and 10% of the price, set by rule 8: $107,900 to $215,800 at the median new-sale price of $2,158,000 in the year to 30 August 2026. It buys an option in the prescribed Form 2, which only you can use, and the developer cannot grant anyone else an option on that unit while yours stands.
Rule 8: a buyer pays for the option "a booking fee … which is not less than 5% but not more than 10% of the purchase price of the unit". In return, the developer "shall give to an intending purchaser … an option for the purchase which shall be in Form 2" (rule 10(1)), granted "upon acceptance by the housing developer of the booking fee" (rule 10(1A)). The option "shall not be assignable or transferable" (rule 10(2)), and the developer "shall not grant to any other person an option to purchase the same unit until after the first-mentioned option has lapsed" (rule 11(1)) (Rules).
Form 2 also names where the money goes: the booking fee is paid to the developer's project account, the account URA says is regulated under the Housing Developers (Project Account) Rules (URA).
At the median new-sale price of the past year, $2,158,000, the booking fee alone is $107,900 at 5% or $215,800 at 10%.
The booking fee buys time and exclusivity, not the home.
How long is the option to purchase valid, and what if you do not exercise it?
Three weeks from the day after the developer delivers the title deeds (or copies) and the execution copies of the sale and purchase agreement to you or your lawyer, which Form 2 requires within 14 days of the option date. If you let it lapse, or give written notice, the developer refunds 75% of the booking fee within 4 weeks and keeps 25%: $26,975 on a 5% booking fee at the median price.
Rule 11(2): the option is "valid for a period … of 3 weeks commencing from the date immediately after the delivery to the option holder, or to the option holder's solicitors, of — (a) the title deeds, or copies of the title deeds to the unit; and (b) the execution copies of the agreement for the sale and purchase of the unit". The Controller can allow a different or varied period, and if you give written notice that you will not exercise, the option lapses on receipt (rule 11(5)).
Form 2 fills in the rest (Rules):
- Delivery. The developer sends the title deeds and execution copies "within 14 days after the Option date".
- Exercise. "sign all the execution copies of the Sale and Purchase Agreement; and (b) return them", then pay "20% of the Purchase Price less the Booking Fee" on exercise or "within 8 weeks after the date of this Option".
- Walking away. "the Vendor will refund to the Intending Purchaser 75% of the Booking Fee within 4 weeks". You return the title deeds and execution copies, and the developer may hold the refund until any caveat you lodged is withdrawn, or until you confirm in writing that you lodged none.
At the median new-sale price, the 25% kept is $26,975 on a 5% booking fee, or $53,950 on a 10% one. What a caveat is, and how it is withdrawn, is in caveats: caveator vs caveatee.
Three weeks to decide, and a quarter of the booking fee is the price of changing your mind.
What payment schedule do the Housing Developers Rules set?
Forms 4 and 5, the prescribed agreements for landed and strata units, fix it: 20% (including the booking fee) on signing or within 8 weeks of the option, 40% in six construction stages, 25% at TOP, and the last 15% at completion and the Certificate of Statutory Completion. On the median new-sale price of $2,158,000, that is $431,600 up front and $539,500 at TOP.
Form 5 (strata units), clause 5: "The Purchaser shall pay the Purchase Price to the Vendor in instalments according to the Payment Schedule", with the same percentages in Form 4 (landed units), each construction stage "within 14 days immediately after the date on which the Purchaser receives" the developer's notice (Rules). On the past year's median new-sale price:
| Stage | Share of the price | At the median price |
|---|---|---|
| Upon signing the S&P agreement, or within 8 weeks after the option date (includes the booking fee) | 20% | $431,600 |
| Foundation work completed | 10% | $215,800 |
| Reinforced concrete framework completed | 10% | $215,800 |
| Partition walls completed | 5% | $107,900 |
| Roofing or ceiling completed | 5% | $107,900 |
| Door and window frames in, electrical wiring, internal plastering and plumbing done | 5% | $107,900 |
| Car park, roads and drains serving the project completed | 5% | $107,900 |
| TOP (or CSC) issued, with roads, drainage, sewerage, water and electricity done | 25% | $539,500 |
| Completion and CSC (partly held by the Singapore Academy of Law as stakeholder) | 15% | $323,700 |
An illustration at the median; your unit follows its own price. Part of the last 15% is held by the Singapore Academy of Law as stakeholder until the Certificate of Statutory Completion (CSC) and the final payment date.
How banks and CPF fund each stage is covered in the progressive payment scheme. PropKaki's property financial planner works the instalments into your cash and CPF on a real price.
The Rules decide when you pay; your loan only decides who pays it.
Can a developer change the sale and purchase agreement or ask you to waive your rights?
Not without the Controller of Housing. The agreement must be in the prescribed Form 4 or Form 5, and any change made without the Controller's written approval is null and void. A developer may not seek a waiver of your rights, or a release from its own duties, without the Controller's consent, and such an undertaking is unenforceable.
- Fixed form. Rule 12(1)–(2): the agreement is in Form 4 (a unit that is not a strata lot) or Form 5 (a strata lot). Rule 12(4): "Any amendment, deletion or alteration to the agreement … made without the prior approval in writing of the Controller shall be null and void." URA has pre-approved a list of amendments that developers "can adopt … without seeking approval from the Controller" (URA); Form 2 says approved modifications sit in the Second or Third Schedule of the agreement, so read that schedule.
- No waivers. Rule 15(1): the developer "shall not, without the prior consent in writing of the Controller, seek from a purchaser … any waiver of the purchaser's rights under an agreement for the sale and purchase of the unit"; rule 15(2): such an undertaking "shall be unenforceable unless the prior consent in writing of the Controller has been obtained".
- A neutral stakeholder. Rule 12(5): "The Singapore Academy of Law … shall act as stakeholder under the agreements".
- Your money. URA: developers must "open and maintain a Project Account with a financial institution for each project", with deposits and withdrawals "regulated under the Housing Developers (Project Account) Rules" (URA).
- Selling on. If you assign your purchase, the developer must sign a new agreement with the buyer on the same terms (rule 16), charging "a fee not exceeding $200" plus up to "$400" for its lawyer, both before GST.
Breaking the Rules is an offence, with "a fine not exceeding $5,000 or … imprisonment for a term not exceeding 6 months or … both" (rule 19) (Rules).
If a developer hands you a side letter to sign, ask whether the Controller approved it.
What must a new launch advertisement show under the Rules?
The developer's name and licence number, the tenure of the land and any encumbrances, the expected dates for vacant possession and for legal title, and the project's location including its lot number. It must not be false or misleading, suggest a link to a government body, or claim attributes the developer cannot genuinely claim.
Rule 3 lists what an advert (other than on radio or television) must include: "(a) the name and the licence number of the housing developer; (b) the tenure of the land and encumbrances, if any, to which the land is subject; (c) the expected date when the purchasers of the units in the housing project will be able to take vacant possession of the units; (d) the expected date when the legal title of the units sold will be conveyed to the purchasers; (e) the location of the housing project including the lot number and Mukim/Town Subdivision." Rule 6 bars anything suggesting "any connection with any Government department, statutory body or public building or place" or "any attribute to which the housing developer cannot genuinely make a claim", and rule 7 bars any advert containing "any statement, information or material which is false or misleading" (Rules).
The licence number in the advert is your first check: look it up on URA's licence check. URA also publishes the developers and individuals under its land sales disqualification or sales suspension framework (URA).
A new-launch advert must tell you who is selling, on what land, and by when you get the keys.
What is the ABSD deadline for developers in Singapore?
Developers pay 40% ABSD on residential land. IRAS remits 35% of it upfront for a licensed developer company that, on the standard timeline, starts building within 2 years and completes and sells every unit within 5 years of buying the site; the other 5% is never remitted. Miss a condition and IRAS claws back the remitted ABSD with 5% interest a year; a developer that started and completed on time but sold 90% to 99% of units has the clawback reduced.
IRAS: "The acquisition of sites by housing developers or their trustees are subject to 40% ABSD of which, 35% ABSD may be remitted upfront subject to conditions below. The other 5% ABSD is non-remittable and remains payable within 14 days after the date of acquisition." The conditions include: "The developer must be a company and a licensed housing developer"; "Commence housing development on the residential site within 2 years"; and "Complete the housing development and sell all units of housing accommodation in the development within 5 years from the acquisition date" (IRAS).
If the conditions are not met, the developer repays the remitted ABSD "together with interest thereon at the rate of 5% per annum". Since 16 February 2024, for land bought on or after 6 July 2018, the clawback is reduced by the proportion of units sold, "provided that the commencement and completion of works criteria are also fulfilled": for land bought on or after 16 December 2021, selling 99% by the deadline means a 25-point clawback rather than 35, and below 90% the full 35 points apply.
The 2-and-5-year timeline is the standard one. IRAS allows extensions for "Complex projects; and Projects submitted through CORENET X in the relevant qualifying period", and PropKaki covered the July 2026 change for large en bloc sites in our news commentary.
Developers are also exempt from seller's stamp duty on what they build: IRAS says licensed housing developers "need not pay SSD when selling residential properties developed by them" (IRAS).
For a developer, the standard ABSD clock starts the day it buys the land: two years to start, five to build and sell every unit.
Is it illegal to rent out a property for less than 3 months in Singapore?
Yes. URA says all residential properties in Singapore may not be used for short-term accommodation, meaning stays of less than three consecutive months, and the Planning Act allows fines of up to $200,000. HDB flats have a stricter floor: each tenant must rent for at least 6 months. This is the Planning Act and HDB's rules, not the Housing Developers Rules.
URA: residential properties "are not allowed to be used for short-term accommodation – defined as stays of less than three consecutive months" (URA). The Planning Act treats such a stay as development needing permission, with "a fine not exceeding $200,000" (Planning Act). For HDB flats: "The minimum rental period for each tenant must be 6 months per application" (HDB). The full rules are in the minimum rental period in Singapore.
Three months for a private home, six for an HDB flat.
How do you check a developer before you book?
Look up the licence on URA's online licence check, and check URA's list of developers under land sales disqualification or sales suspension. The advert and the option must both carry the developer's licence number. For the biggest developers, PropKaki ranks them by the government land they have won.
Three checks before you book:
- The licence. URA's Check Validity of Housing Developer's Licence "allows you to check if a developer holds a valid housing developer's licence".
- Sanctions. URA's land sales disqualification and sales suspension framework lists "developers and/or individuals subject to land sales disqualification and/or sales suspension" (URA).
- The paperwork. Both the advert and the option must carry the developer's licence number (rule 3; Form 2).
For who the biggest developers are, see Singapore's biggest property developers, ranked, and for each launch's developer, prices and sales, PropKaki's new-launch reviews.
Size is not a licence: check both.
What is the biggest mistake new-launch buyers make with the Housing Developers Rules?
Paying the booking fee as if it were a refundable deposit. It is 5% to 10% of the price, and if you do not exercise the option the developer keeps a quarter of it: $26,975 on a 5% fee at the median new-sale price. Read the Form 3 information and line up your loan before you pay, not during the three weeks.
The Rules protect you in many ways: a prescribed contract, a capped fee, a fixed schedule, a project account and a neutral stakeholder. They do not protect you from changing your mind. Form 2 refunds "75% of the Booking Fee" if you walk away (Rules), and the three weeks start from delivery of the documents, which the developer must send within 14 days of the option date.
Use the time before the booking fee, not after it: the Form 3 information must be in your hands first (rule 10(4)), and your loan and CPF can be checked before you commit.
The cheapest time to walk away from a new launch is before the booking fee.
