Purchasing a resale HDB flat in Singapore represents a significant milestone, but determining what to renovate can feel overwhelming. This comprehensive guide provides everything you need to know about renovating your resale HDB or BTO resale flat in 2025, including essential renovation priorities, accurate costs, and step-by-step planning strategies.
Quick Answer: Essential renovations for resale HDB flats typically include kitchen upgrades, bathroom renovations, electrical rewiring, flooring replacement, and carpentry work. Complete renovation packages range from $11,490 to $37,490+, depending on flat size and specifications, with most homeowners prioritising safety-critical areas first.
Why Resale HDB Renovation Differs From BTO Projects
Resale HDB renovations present unique challenges compared to new BTO projects. Unlike brand-new flats, resale properties often require structural assessments, utility upgrades, and compliance updates to meet current HDB regulations. Additionally, previous renovations may need rectification, and the 3-year bathroom renovation rule significantly impacts planning for newer resale flats.
Understanding these distinctions helps you budget effectively and prioritise renovations that deliver maximum value. HDB renovation permits may also differ for resale properties, particularly when structural modifications are involved.
Essential Renovation Priorities for Resale HDB Flats
Strategic renovation planning ensures you address critical areas first whilst maximising your investment return. Here are the key priorities for resale HDB renovation projects:
Safety and Compliance First
Begin with safety-critical renovations that ensure compliance with current HDB regulations:
- Electrical System Assessment: Older flats may require complete rewiring to meet safety standards
- Plumbing Inspection: Check for leaks, water pressure issues, and pipe condition
- Structural Integrity: Identify any unauthorised modifications requiring rectification
- Fire Safety Compliance: Ensure smoke detectors and safety features meet current requirements
Essential Living Areas
Focus on spaces that impact daily comfort and property value:
- Kitchen Renovation: Often the heart of family life, requiring modern appliances and efficient layout
- Bathroom Upgrades: Critical for hygiene and comfort, especially in older flats
- Flooring Replacement: Addresses wear, safety, and aesthetic concerns
- Built-in Storage: Maximises space efficiency in compact HDB layouts

Luxury 5-room packages can reach $37,490+ depending on finishes and customisation requirements.
Do I need permits for resale HDB renovation?
Permit requirements depend on the scope of renovation work. Hacking, plumbing relocations, major electrical work, and structural modifications require HDB approval. Cosmetic renovations like painting, overlay flooring, and cabinet installations typically don't require permits. Professional contractors handle permit applications to ensure compliance.
Can I hack walls in my resale HDB flat?
Wall hacking is permitted with proper HDB approval, but restrictions apply to structural and load-bearing walls. Non-structural partition walls can typically be removed or modified with appropriate permits. Professional structural assessment ensures safe modifications whilst maintaining building integrity and compliance with HDB regulations.
What is the 3-year bathroom renovation rule for resale HDB?
The HDB 3-year bathroom renovation rule restricts major bathroom modifications within three years of the previous renovation. This regulation prevents excessive renovation disruption and maintains reasonable standards. Check your flat's renovation history before planning extensive bathroom work, as violations can result in penalties.
How long does resale HDB renovation take?
Complete resale HDB renovation typically takes 8-12 weeks, depending on project scope and complexity. Basic renovations may complete within 6-8 weeks, whilst comprehensive projects involving extensive hacking and system upgrades require 10-12 weeks. Permit processing adds 2-3 weeks to initial timelines.
Should I choose renovation packages or individual contractors?
Renovation packages typically offer better value, coordinated project management, and comprehensive warranties. Package pricing provides transparency and often includes 15-30% savings compared to individual project pricing. Established contractors with package offerings also handle permits, scheduling, and quality control more effectively.
What should I renovate first in a resale HDB flat?
Prioritise safety-critical renovations first: electrical systems, plumbing, and structural compliance. Next, focus on essential living areas including kitchen and bathroom upgrades. Finally, address cosmetic improvements like flooring, painting, and built-in storage. This approach ensures safety whilst maximising investment returns.
Can I stay in my flat during resale HDB renovation?
Living arrangements depend on renovation scope and duration. Minor renovations allow continued occupancy with some disruption. Major projects involving hacking, electrical work, or bathroom renovations may require temporary relocation for 2-4 weeks. Discuss accommodation options with your contractor during planning.
