Choosing a contractor for a 3Gen service yard in Singapore
A 3-Generation flat service yard serves a busy household, so the right contractor makes or breaks the job. This HDB Renovation Guide Singapore explains the HDB rules that apply and gives a practical checklist for choosing a contractor. The main point: register, insure, and scope the yard before you sign, and the laundry corner gets done without a dispute.
Why contractor choice matters in a 3Gen yard
The 3Gen service yard handles laundry for three generations, often with a washer, a dryer, and mobility needs if a senior lives there. A poor contractor hacks the wrong floor, misses the point cap, or vanishes mid-job. HDB rules require that only HDB-registered contractors carry out regulated works, applied through the Renovation Contractor Registration System. The yard floor hack is restricted, the original screed stays, and the bomb shelter wall cannot be altered. Pick well and these rules are followed; pick badly and you wear the redo.
HDB rules that apply to the yard
- Only HDB-registered contractors may do regulated works; check the RCRS listing before signing.
- The original reinforced concrete screed cannot be hacked; use overlay or tile-on-tile with approval.
- New power points for the washer stay within HDB's capped count, done by the registered firm.
- The bomb shelter door, frame, and walls stay untouched; plan storage around them.
- Windows need HDB-approved contractors with shatter-resistant glass; aluminium rivets need regular checks.

A practical contractor checklist
- Confirm HDB registration and ask for the RCRS number in writing.
- Check CaseTrust accreditation and Renovation Continuity Insurance so you are covered if the firm fails.
- Ask for a scoped quote that names the yard floor, the carpentry, and the points separately.
- Confirm the noise schedule: hacking 9:00am to 6:00pm, Monday to Saturday, quiet only on Sundays.
- Get the permit plan in writing, including who applies through HDB e-Services.
- Walk a past 3Gen or similar yard project if the firm has one to show.
Costs and timeline
A 3Gen service yard renovation runs S$2,000 to S$5,000 for carpentry and lighting, part of the S$50,000 to S$75,000 class reno. Resale renovation takes 10 to 16 weeks; BTO takes 8 to 12 weeks. A registered firm with insurance protects the timeline if it hits trouble. Pay in stages tied to milestones, not up front.
