1) Who sets condo renovation rules?
Renovation rules for condos are set by the MCST (your condo’s management). They operate under the Building Maintenance and Strata Management Act (BMSMA) and guidelines from BCA. This means rules can vary between condos, but all must follow building safety codes, fire safety (SCDF), and URA usage guidelines. Also remember rules on AirBnB In Singapore !
2) What renovations are typically allowed?
Generally, condo owners can renovate inside their unit, provided works do not affect common property or structural integrity. Commonly allowed works include:
- Painting internal walls
- Replacing flooring, cabinetry, kitchen fittings
- Installing air-con units (subject to guidelines)
- Bathroom upgrades
- Electrical rewiring by licensed electricians
Tip: Renovations inside your unit are still subject to MCST approval. Always check with your condo’s management company.
3) What renovations are restricted or banned?
You cannot alter common property or the building’s external façade. Examples:
- Changing external windows without BCA/MCST approval (BCA window safety rules)
- Extending balconies, merging units, hacking structural walls
- Changing main doors, gates, or lobbies (common property)
- Installing unauthorised awnings or grills visible from outside
- Heavy hacking without BCA permits

4) Approval process & permits
Before works start, you must:
- Submit renovation application to MCST (with contractor details & insurance).
- Engage only BCA-registered contractors for structural/major works.
- Comply with fire safety requirements if works affect sprinklers, alarms, or smoke control.
Some condos also require a refundable renovation deposit to cover potential damage to common areas.
5) Renovation hours & noise control
Most condos restrict noisy works (drilling, hacking) to weekdays between 9am – 5pm, excluding Sundays and public holidays. This varies by MCST but is consistent with NEA noise regulations.

6) Tips for smooth condo renovations
- Hire experienced ID firms familiar with condo restrictions.
- Get written approval before making payments to contractors.
- Plan works early to avoid delays in moving in.
- Budget for possible MCST deposits in addition to buying costs.
- Communicate with neighbours about noisy works to maintain goodwill.
