Singapore HDB Renovation Rules 2026: What You Cannot Do Without Permission

Every HDB renovation in Singapore must comply with HDB guidelines. Violating these rules can result in fines, mandatory restoration at your own cost, and complications when you sell the flat. Here is what you need to know in 2026.

Works That Require HDB Approval

Hacking of walls: Structural walls and certain non-structural walls require approval before hacking. Your contractor should advise, but verify independently via the HDB e-Service portal.

Removal of household shelter (bomb shelter) door: Not permitted.

Widening of doorways: Requires approval if the doorway is load-bearing.

Installation of window grilles: Must comply with HDB specifications on materials and design.

Works That Do NOT Require Approval

Most carpentry works do not require HDB approval. This includes kitchen cabinets, wardrobes, TV consoles, storage cabinets, and feature walls — as long as no structural elements are affected.

Painting, flooring replacement (where tiles are not being hacked), and installation of false ceilings also generally do not require approval.

The 1 Month Rule for New BTO Flats

For new BTO flats, renovation cannot commence until one month after key collection. HDB needs this time to complete the defect inspection process for the entire block.

Renovation Hours in HDB

Noisy renovation works (drilling, hacking) are only permitted Monday to Friday 9am–5pm, and Saturday 9am–1pm. No renovation work is permitted on Sundays or public holidays.
