Planning to Hack a Wall in Your HDB Flat?
Open-concept living rooms, semi-open kitchen counters, and expanded master bedrooms are among the most popular home renovation ideas in Singapore today. However, before you take a sledgehammer or rotary breaker to any wall, understanding HDB's statutory demolition guidelines is critical to prevent hefty fines, structural damage, or stop-work orders.
💡 Quick Golden Rule
Never hack any wall before obtaining the official written HDB Renovation Permit. All hacking works must be carried out by a contractor listed on the Directory of Renovations Contractors (DRC).
1. Identifying Load-Bearing Columns vs Non-Structural Walls
In HDB architecture, structural stability relies on reinforced concrete (RC) walls, pillars, and shear beams. HDB strictly strictly prohibits hacking, drilling deeply, or altering any structural element.
- Solid RC Shear Walls / Columns (DO NOT TOUCH): Indicated on your HDB floor plan by dark, solid bold lines. These support the structural weight of the floors above you. Tampering with RC columns is illegal.
- Non-Structural Partition Walls (Hacking Allowed with Permit): Indicated by thin or hollow lines on floor plans. These are typically lightweight concrete blockwork or drywall partitions separating rooms or closing off kitchens.
2. The HDB Hacking Permit Application Workflow
Securing approval is straightforward when working with an experienced direct contractor like Tabeeb Contractor:
- Blueprint Review: We inspect your official HDB floor plan to verify that the target walls are strictly non-structural.
- Online Submission: The licensed contractor submits an electronic permit application via the My HDBPage portal along with marked layout plans.
- Approval Processing: Approvals typically take between 3 to 7 working days depending on HDB branch workload.
- Commencement Notice: Mandatory notices must be posted outside the flat and at the lift lobby at least 3 days prior to notify neighbors of noisy hacking hours.
⚠️ Permitted Noise Hours for HDB Hacking
HDB permits heavy, noisy works (demolition, floor tile hacking, and rotary drilling) strictly from 9:00 AM to 5:00 PM on weekdays only. No noisy works are permitted on Saturdays, Sundays, or Public Holidays.
3. What Does HDB Hacking Typically Cost?
Hacking costs depend primarily on the length and height of the wall, whether tiles are being stripped, and haulage accessibility:
- Standard 10-ft Non-Structural Wall Hacking: S$500 – S$900
- Living & Dining Floor Tile Hacking (4-room HDB): S$1,600 – S$2,400
- Kitchen & 2 Bathrooms Full Hacking (Floors & Walls): S$2,200 – S$3,500
- Debris Haulage & Disposal to NEA Landfill: Included in comprehensive contractor quotes
