Building Contract Review Before Signing: What Homeowners Should Check

Signing a residential building contract is a major financial commitment. The contract usually does much more than record the price. It sets out the builder’s obligations, the owner’s obligations, the payment stages, the scope of work, the treatment of variations, delay rights, allowances, exclusions, insurance requirements and the process for resolving disputes.

Many homeowners focus on the headline price and the drawings. That is understandable, but it is not enough. The contract documents need to be read together. The written contract, special conditions, specifications, inclusions list, exclusions list, plans, engineering details, provisional sums, prime cost items and builder’s quote can all affect what the owner is actually buying.

One of the first issues to check is whether the scope of work is clear. If the contract says one thing, the plans say another thing, and the quote is silent, there is room for argument later. Ambiguity usually becomes expensive once work has started.

The second issue is the price. A fixed price contract may still contain allowances, prime cost items, provisional sums, excluded works and adjustment clauses. Those items can change the real cost of the project. The owner should understand what is fixed, what is only estimated, and what may be charged later.

The third issue is time. The contract should explain when work starts, how long it should take, what happens if the builder is delayed, and when the builder can claim an extension of time. Delay clauses can affect both completion and the owner’s ability to claim compensation.

The fourth issue is variations. Variations should be properly priced and approved before the work is carried out. A loose variation process can create disputes about whether work was authorised and how much it should cost.

The fifth issue is risk allocation. Some contracts shift important risks to the owner through special conditions or qualifications in the quote. These may deal with site conditions, engineering changes, council requirements, supply delays, rock, soil, drainage, service connections or design responsibility.

A contract review before signing is not about stopping the project. It is about identifying the issues early, so they can be clarified, negotiated or understood before the owner is locked in.

The best time to review a building contract is before signing. Once the contract is signed, the owner’s bargaining position is much weaker.
