The 5 Hidden Costs in Home Construction You Must Prepare For

When contractors give you an estimate of "₹1,800 per square foot," they almost always leave out crucial expenses. Here are 5 hidden costs you must include in your budget:

1. Government Approvals and Fees

Getting your building plan sanctioned by the local municipal corporation (BBMP, BMC, etc.) involves official fees, architect sign-offs, and sometimes unofficial facilitation charges.

2. Temporary Electricity and Water

Before construction begins, you need a temporary electricity meter and a borewell or water tanker supply. Commercial electricity rates apply to construction sites, which are significantly higher than residential rates.

3. Compound Wall and Gates

Contractors calculate the built-up area of the house. The boundary wall, heavy iron entry gates, and exterior paving/landscaping are almost always billed separately.

4. Anti-Termite and Waterproofing

Basic estimates rarely include comprehensive chemical waterproofing for the roof and bathrooms, or pre-construction anti-termite treatment for the foundation. Skipping these will cost you lakhs in repairs later.

5. Material Wastage

Sand blows away, cement hardens if exposed to moisture, and tiles break during transit. Always account for a 5% to 10% wastage margin on all finishing materials.
