Must-Know HDB Guidelines for Resale Flat Renovation

Renovating a resale HDB flat is a big task. It needs planning and following many rules. Singapore's Housing and Development Board (HDB) has set these rules to keep all flats safe, clean, and strong. These rules help people fix or change parts of their homes without harming the building or bothering neighbours. If you start without knowing the rules, you may face trouble. You could waste money or time fixing mistakes. Some works need approval. Some are not allowed. It is essential to check before doing anything. This guide explains what you must follow when planning a resale flat renovation.

Whether you just bought an older unit or want to refresh your space, this will help. Follow along to learn how to handle your resale HDB renovation correctly.

HDB Approval: When It’s Required

Structural Works Need Permission

You cannot tear down or cut through particular walls. These walls hold the flat together. If you change them, it can weaken the building. Before doing anything to walls, give your plans to HDB. They will check and approve if it is safe.

Always use a contractor from HDB's approved list. These workers understand the rules and know how to work safely. You must not touch intense beams or columns.

Window Replacements Must Be Certified

Want to replace old windows? Choose someone HDB and the Building and Construction Authority (BCA) approved. Windows must meet safety rules. If the windows fall off, they can hurt people downstairs. Only use safe hinges and stainless steel parts.

Flooring and Tiling Regulations

Wet Work Has Time Restrictions

Many people change floor tiles when resale flat renovation. But wet works like tiling must be finished within three days. You also need to ask HDB before removing old tiles.

In bathrooms, the waterproof layer under the tiles is essential. HDB checks this layer before they say yes to your plans. If you break the waterproofing, water may leak into the flats below.

Bathroom Works Have a Mandatory Wait

If your resale HDB renovation flat  is new (less than three years), you must wait before changing the bathroom floors. HDB uses exceptional waterproofing in new flats. Let it set appropriately before making changes. After waiting, use a contractor who follows HDB rules to change tiles.

Kitchen and Bathroom Guidelines

Let Plumbers Handle the Pipes

Don't fix or move water pipes on your own. Always hire a plumber with a licence from the Public Utilities Board (PUB). If you move a sink or add a water point, check first. Never shift water drains without asking. HDB checks these carefully to stop water problems.

Leave Gas to the Pros

Gas is valuable but dangerous if mishandled. Only trained workers can fix gas pipes or install stoves. Do not move gas pipes yourself. One mistake can cause a leak, fire, or explosion. So, always call the right people.

Electrical and Air Conditioning Works

Electric Work Needs the Right Hands

Electric wires carry strong currents. Only a licensed electrician should handle changes. Want to add plugs or lights? Let your electrician tell SP Group before doing the job.

If you want an aircon system, check if your flat has enough power to support it. Don't overload the system.

Install Aircon the Right Way

Air conditioners help cool your flat. However, installing them incorrectly may cause water damage. Pipes and wires should not cut into walls or floors. Follow HDB's aircon guide. Place outdoor units in allowed areas only.

Be Careful with Doors and Gates

Use Fire-Rated Doors if Needed

Want to change your main door? If it faces a shared corridor, it must be fire-rated. Fire-rated doors slow down flames and help save lives. Buy from sellers who know HDB and fire safety 

rules.

Ask Before Moving the Gate

You can't just shift or replace the main gate as you like. You need approval. The gate must fit the flat's look and size. Don't add designs that may block passage or cause danger.

General Renovation Rules and Work Hours

Work at the Right Time

You must follow HDB's work time rules. You can only do renovation from Monday to Saturday, 9 am to 6 pm. Hacking, drilling or noisy work is only allowed during the first three weekdays after you begin.

You must stop all work on Sundays and public holidays. This helps keep peace for neighbours.

Don't Block Shared Spaces

Keep tools and materials inside your flat. Don't leave them in corridors, staircases, or lifts. Always use covers to protect shared floors and walls. Clean up every day. This shows respect to others in your block.

Hiring Registered Renovation Contractors

Use HDB-Approved Workers

You must hire a contractor from the HDB Registered Renovation Contractor Scheme (RRCS). These workers know all the rules and follow them. If you pick someone else, you may get into trouble.

Contractors Must Apply for You

Your contractor must send in the permit request to HDB before starting any work. They also must fix any mistakes. Ask them to give you a copy of the approval letter before they begin.

Renovation Notice and Neighbors’ Rights

Give Advance Notice

Let your neighbours know about your plans. Contractors must give a standard HDB notice to flats nearby. This helps avoid noise complaints and makes things smoother.

Protect Shared Property

Ensure your contractor uses boards to shield floors in the lift and corridors. If they damage anything, HDB may charge you. So, protect all areas from start to end.

The End Note

When you fix or upgrade a resale flat, follow HDB's rules from the very start. These rules keep homes safe and blocks quiet. Don't guess or rush. Plan properly. This helps avoid fines, delays, or removing completed work. Check before touching walls, windows, floors, pipes, or wires. Ask for permission. Use the right people. Only HDB-approved workers should handle the job. Always follow the timing and keep shared spaces tidy. Tell your neighbours early and respect their space.

Renovation helps improve your home, but you must do it right. These HDB rules guide you through a smart and smooth resale HDB renovation. If you follow them, you will finish your work with fewer problems and more peace of mind. Use this guide as your checklist, and move ahead with confidence.
