Questions about build time and payments

How long does it take to build a house?

In the US the Census Bureau's 2025 survey shows 7.4 months from permit to completion for homes built for sale, 11.7 months for a house built by a hired contractor and 14.3 months when the owner builds. Permits, weather and design change this.

How should I pay a builder?

In stages, each after the stage is finished and checked, never in advance. A common example in England: a deposit of 10%, then foundations, walls and roof structure, roof and windows, first fix, second fix, and a last payment held until snags are fixed.

How big should the deposit be?

Planning Signal warns against a builder who asks for more than 10–15% upfront. Many contracts start with 10%.

What is retention?

A small share of each payment, often 5%, kept back until defects are fixed: half at completion and half after the defects period of 6–12 months.
