Reviews
Jeremy had responded quickly to me on the first quote even though I am only doing some renovation to my kitchen and two bathroom. Jeremy is able to provide me with very good advise for the renovation.
We were very grateful to Brandon and his team to complete our renovation within a tight timeline despite many challenges encountered during the renovation. Brandon was a responsible and reliable designer who tried his best to meet our requests. He would immediately rectify issues whenever we visited the site.
Permit Overview: Why Your HDB Renovation Permit Matters
The permit isn’t optional.
You need a valid HDB renovation permit before touching walls, flooring, wiring, or anything that affects the flat’s structure or systems.
Without it, you risk breaking HDB’s rules and may be forced to reverse the work.
That’s time lost and money gone.
Renovation permits exist for safety and uniformity across HDB blocks.
They ensure that your changes won’t harm your neighbours, the structure, or the utilities shared by everyone in the building.
If you’re in a new BTO flat, the restrictions are even tighter during the Minimum Occupation Period (MOP).
HDB has special BTO renovation rules in place to protect the integrity of new buildings.
At 9Creation, we’ve helped hundreds of homeowners understand the specific rules that apply to their unit type.
We handle the permit submission so you don’t have to second-guess anything.

Understanding Key BTO & HDB Renovation Rules in Singapore
Once you’ve got your floor plan and design in mind, you need to check what’s actually allowed.
The HDB rules for interior design in Singapore are strict but clear once you understand them.
For BTO homeowners, the rules differ slightly from resale flats.
Most are designed to preserve safety, reduce disruption, and maintain the new building’s integrity.
Permitted Renovation Works
Here are the key things you can and cannot do:
- No hacking of structural walls. HDB publishes load-bearing wall info in your floor plan, and those walls cannot be removed or altered.
- You can install non-structural partitions, but only after you get approval.
- Electrical works must be done by a licensed LEW (Licensed Electrical Worker) under EMA.
- Flooring replacement is allowed, but certain materials are restricted, and work must comply with noise limits.
All these works require submission of documents showing exactly what will be done.
HDB reviews everything, and your contractor needs to be familiar with the latest guidelines.
Rules can change quickly.
New circulars from HDB might update flooring types, wall finish requirements, or accepted waterproofing methods.
That’s why it helps to work with a team that follows these updates weekly and doesn’t rely on outdated info.
Noise Control & Working Hours
Renovation work is restricted to 9am to 5pm on weekdays.
No works are allowed on Sundays and public holidays.
Noisy works like demolition or drilling can only take place between 9am and 5pm on weekdays for a maximum of 3 days.
These are strict rules and your neighbours will report any violations quickly.
Contractors must display the permit at the unit’s entrance and notify the building management before starting noisy works.
Disposal of Debris
Waste generated from hacking, tiling, or carpentry must be disposed of by approved services.
Contractors cannot leave debris in common corridors, lift lobbies, or HDB chutes.
Scheduling disposal ahead of time avoids delays and keeps your renovation within the terms of your permit.
If you’re unsure which parts of your project need clearance, we can help clarify in a free consultation.
Timeline & Checklist: Your Renovation Permit Journey
Renovation delays often happen before work even starts.
That’s because homeowners or contractors didn’t prepare the required documents or misunderstood what needed approval.
The permit process in Singapore follows a fixed sequence.
Here’s how it typically works:
- Hire a HDB-licensed renovation contractor who can access HDB’s e-submission system (RENOVATION e-SERVICES).
- Work with your contractor to finalise layout drawings and renovation plans. Include floor plans, proposed changes, and material details.
- Submit the plans via RENOVATION e-SERVICES. HDB will review them in about 7 to 10 working days.
- If HDB requests clarifications or changes, revise and re-submit as needed.
- Once approved, your contractor can start work. A copy of the permit must be displayed clearly at the flat entrance.
Most projects that involve wet works, carpentry, and hacking need this process.
Even if you’re just changing your toilet tiles, you still need clearance if waterproofing is affected.
Here’s an estimated breakdown of how long each phase may take:
| Stage | Timeframe | Action Required |
|---|---|---|
| Document Preparation | 5–10 days | Finalise layout drawings and list of works |
| Permit Submission | 7–10 working days | Submit through HDB system and monitor status |
| Revision (if needed) | 2–5 days | Respond to HDB feedback and resubmit |
| Work Start | Immediate after approval | Begin renovation, permit must be displayed |
Having the right team means fewer back-and-forths.
At 9Creation, we build the project schedule based on your permit timeline so the start and finish stay predictable.

Hiring Licensed Contractors: Your Key to Compliance and Quality
Contractors aren’t all the same.
Working with an unlicensed contractor can cause major setbacks—especially if they submit incorrect documents or skip approval steps.
HDB requires all hacking, tiling, and structural work to be done by contractors on its approved list.
They’re the only ones allowed to submit permit applications under the official HDB e-portal.
In a recent 2023 Singapore housing study, 78% of homeowners said working with a licensed contractor helped them avoid delays and unexpected renovation issues.
What makes licensed contractors different is not just paperwork—it’s their understanding of BTO and HDB-specific limits.
They know what to avoid, how to sequence works, and how to prepare compliant designs from day one.
If you’re unsure where to find one, 9Creation connects you to experienced teams who’ve worked on flats like yours across Singapore.
Every contractor we recommend is licensed, vetted, and used to working under real-world HDB timelines.
