HDB Renovation Timing & Noise Rules

Permitted renovation hours

"Noisy works" is the category that catches owners out: hacking and drilling can't run on Saturdays, which is why the demolition phase of a renovation is always scheduled across weekdays. A contractor promising Saturday hacking is promising you a stop-work order.

How long is a renovation allowed to take?

HDB caps the duration of renovation under each permit — broadly, around three months for renovations in newly completed (BTO) blocks and one month for occupied/existing blocks' noisy phases, with the full schedule declared in the permit application. In practice this is rarely the constraint: our small renovations finish within 30 days and whole-flat projects within 8–11 weeks, comfortably inside the allowed windows. What matters is that your contractor declares an honest schedule and sticks to it.

Neighbour notices and common-area protection

Before works start, contractors must display the renovation notice (with permit details and contact numbers) on your front door, and notify neighbouring units. Lift lobbies and corridors used for haulage must be protected, and debris removed daily — not stockpiled at the void deck. These small disciplines are what keep neighbour relations intact for the weeks you're renovating; we treat them as non-negotiable.

Planning around the rules

• Front-load the noise. We compress hacking and drilling into the earliest possible weekday block so the loud phase is over in days, not spread across weeks.
• Living in during renovation? Schedule wet works and noisy phases first while you stay elsewhere for a week or two, then move back for the quieter carpentry and finishing phases.
• Festive seasons: public holidays and Sundays don't count as work days — factor CNY, Hari Raya and year-end clusters into your timeline expectations.
