1. Understanding Renovation Budget Basics
A renovation budget is your total financial plan for home improvements, including materials, labor, permits, and contingencies. In Singapore, budgets must account for HDB/URA regulations to ensure structural safety and compliance.

Key Components of a Renovation Budget

2. Singapore-Specific Factors Affecting Costs

HDB Regulations You Must Know
- Obtain HDB clearance before hacking.
- False ceilings need fire-rated materials.
- Maximum flooring height: 12mm for HDB.
Insider Tip: Check HDB InfoWEB for your flat's renovation status—many resale flats hide prior unauthorized works.
