Every renovation in an HDB flat must be done by a contractor on HDB’s Directory of Renovation Contractors. Here’s what that listing means and how to check a contractor before you sign.
Updated 26 October 2026
In short: HDB requires flat owners to use contractors listed in its Directory of Renovation Contractors (DRC). Check the contractor on HDB's official DRC page before signing. A listing means the firm may do HDB renovation work; it is not HDB's guarantee of quality, and contractors can be delisted for demerit points.
The Directory of Renovation Contractors (DRC) is HDB’s list of contractors allowed to carry out renovation works in HDB flats. Flat owners must engage a DRC-listed contractor, including for works that don’t need a permit.
| It means | It doesn’t mean |
|---|---|
| The contractor may carry out renovation in HDB flats | HDB recommends the contractor |
| The contractor can apply for HDB renovation permits | HDB guarantees the quality of the work |
| The contractor is subject to HDB’s demerit system | The price is fair; compare itemised quotations |
The DRC applies to HDB flats. Condos follow their management corporation’s renovation rules, and HDB shops and offices have separate tenant guidelines. For commercial units at lease end, see what reinstatement means.
