Small renovation works sit in an awkward gap in Singapore. They are too big for a handyman, who is not equipped for hacking and reinstatement, and often too small for a full renovation contractor to be interested. Homeowners are left unsure who to call for a partition, a patch-up, or a small layout change — and, more importantly, unsure what requires HDB approval.

Getting the approval question wrong is expensive. Carrying out renovation works without the required permit can attract a fine of up to S$5,000, and you may be ordered to reinstate the works at your own cost.⁴ This guide explains what small renovation works typically involve, when approval is needed, and how to scope a project properly.

What Counts as 'Small Renovation Works'?

Broadly, small works are alterations that are limited in scope and do not involve structural change. Typical examples include:

• Installing a lightweight internal partition to create a study or storage area.
• Built-in shelving and small carpentry fixing.
• Minor hacking to remove a fixture, old finish or small section of wall.
• Patching and reinstatement after plumbing or electrical work.
• Patch painting and touch-up after other contractors finish.
• Small layout modifications for a home office.
• Removal and disposal of old fixtures and shelving.

These are the jobs that most commonly fall between trades, and they are exactly the kind of work a multi-trade contractor can handle efficiently because electrical, plumbing, painting and handyman tasks can be coordinated in one scope.

When Does HDB Approval Apply?

The critical distinction is between cosmetic work and work that affects the structure or external appearance of the flat. HDB applies the same structural safety standards and approval process across all flats, regardless of age, and contractors must obtain HDB's approval before commencing any renovation works that may affect the structure.⁴

Specifically, HDB's wall-work rules require approval for partial or complete demolition or alteration of internal lightweight partition walls, including brick walls and drywalls.⁴ The appearance of a partition does not determine whether it is structural — a lightweight-looking wall may still require approval to remove or alter. This is the single most common misconception among homeowners.

Other works that generally require permit approval include changing the bomb shelter door and certain window or grille alterations.⁴ All renovation works generally require a Qualified Person (QP) to submit an application to the authorities, and a Notice of Alteration (NOA) is required if works involve hacking and laying of wall or floor tiles.⁴

Permits, Timelines and Responsibility

As the flat owner, you are responsible for obtaining all HDB renovation permits required for your flat before works begin.⁴ Upon approval, renovation should be completed within 3 months for new flats and 1 month for existing flats.⁴

This matters when you are planning a small job. A partition installation that seems like a two-day task can stretch if approval is not obtained first. A reputable contractor will flag likely approval requirements during the site visit rather than starting work and hoping for the best.

What a Small Renovation Scope Should Include

A properly scoped small renovation quotation should list every task separately so you can see what you are paying for:

• Hacking and removal — what is being removed, and how debris will be disposed of.
• Partition or carpentry — materials, dimensions and fixing method.
• Electrical and plumbing alterations — points to be added, moved or made safe.
• Patching and reinstatement — filling, sanding and surface preparation.
• Patch painting — whether the full wall or only the patched area is being painted, and whether a colour match is guaranteed.
• Protection and clean-up — floor covering, dust containment and debris removal.
• Approval coordination — who is responsible for permit submission, if required.

A vague lump-sum quote for 'small reno works' gives you no way to compare contractors or verify what was actually done. Insist on an itemised scope.

Why Multi-Trade Capability Matters for Small Jobs

A partition installation that also requires a new power point, patching, and painting involves three trades. If each trade is a separate contractor, you coordinate three schedules, three quotations and three sets of protection and clean-up. A contractor who covers electrical, plumbing, painting and handyman work in-house can complete the whole scope with one quotation, one schedule and one point of accountability.

This is particularly valuable for snag list completion before handover or rental, where a dozen small defects across multiple trades need to be resolved quickly.

Common Mistakes to Avoid

• Assuming a partition is non-structural because it looks thin. Approval is based on the wall type and structural role, not appearance.
• Starting work before approval. The fine and reinstatement cost far exceed the time saved.
• Using an unregistered contractor. You have no recourse if the work is defective or fails inspection.
• Not confirming work hours. HDB and condominium rules restrict noisy work to specific hours, and drilling outside those hours can result in complaints and stoppage.
• Skipping reinstatement in the quote. Hacked walls left unpainted become a second project and a second cost.

Frequently Asked Questions

Do I need approval to build a partition in my HDB flat?

If the work involves demolishing or altering an existing partition wall, approval is generally required. For a new lightweight partition, the requirements depend on the method and the wall's relationship to structure. Confirm with HDB or a Qualified Person before proceeding.

Can I remove a non-structural wall without approval?

Not automatically. HDB's rules require approval for partial or complete demolition or alteration of internal lightweight partition walls, including brick and drywall. Appearance alone does not establish that removal is permitted.⁴

How long does HDB renovation approval take?

Timelines vary depending on the submission and the scope. Build the approval period into your project schedule rather than assuming work can start immediately.

What happens if I renovate without approval?

You may face a fine of up to S$5,000 and be required to reinstate the works. Unapproved structural alteration can also affect your insurance and resale.
