General Contractor Contract: Template and Key Clauses (2026)

A general contractor contract governs a construction or renovation project where one contractor takes charge of the work, hires subcontractors, and delivers a finished result to the owner. It covers the build, the price, the schedule, how changes are handled, and who carries the risk if things go wrong. These projects involve large sums, many trades and real safety risk, so a weak contract is expensive. This guide gives you a usable clause-by-clause skeleton, explains what each part does, and flags the mistakes that cause trouble. This is general information, not legal advice. Construction law, licensing and lien rules differ sharply by country and even by state or city, for example the United States, the United Kingdom and India, so have any significant construction contract checked by a professional in your jurisdiction before you sign. ## When you need this contract Use a written contract for any construction or major renovation job. It matters most when the work runs for weeks or months, when subcontractors and suppliers are involved, when permits and inspections apply, and when payment is staged against progress. A clear contract is the single best protection against the disputes that construction is known for: cost overruns, delays and arguments over quality. ## The clause-by-clause skeleton 1. Parties and project. Name the owner and the general contractor in full, with addresses and licence numbers where required, and identify the project and site. Add the start date. 2. Scope of work and drawings. The most important clause. Reference the drawings, specifications and schedule of works that define exactly what is being built. List what is included and, just as important, what is excluded. Ambiguity here is the root of most construction disputes. 3. Contract price and price type. State the price and how it is set: a fixed lump sum, cost plus a fee, or a guaranteed maximum price. Each shares risk differently, so be explicit. Include allowances for items not yet chosen, such as finishes, and say how the price adjusts when the actual cost is known. 4. Payment schedule and retention. Tie payments to progress milestones or a monthly valuation of work done. State due dates, the currency, and any retention, which is a small percentage held back until the job is complete and defects are fixed. State when retention is released. Include a late payment charge. 5. Change orders. State that any change to the scope, whether owner requested or caused by site conditions, must be a written change order with its own price and schedule impact, approved before the work proceeds. This is the single most important clause for controlling cost on a build. 6. Schedule and delay. Set a start date, key milestones and a completion date. Distinguish delays the contractor is responsible for from excusable delays such as extreme weather, permit delays or owner changes. State any damages for late completion and the extension of time process. 7. Subcontractors and suppliers. State that the contractor may use qualified subcontractors but remains responsible for their work, and that the contractor is responsible for paying them. Where lien or similar rights exist, address waivers and proof of payment to protect the owner. 8. Permits and inspections. Say who obtains permits and pays for them, and that the work will meet the applicable building code and pass required inspections. This keeps responsibility clear. 9. Site conditions and safety. Address who is responsible for site safety, access, and unforeseen conditions such as hidden structural or ground problems, which usually become a change order. 10. Insurance and indemnity. Require the contractor to carry general liability and the legally required workers coverage, and to name the owner where appropriate. Set out indemnities fairly. Construction risk is real, so this clause matters. 11. Warranties and defect fixing. Warrant that the work will be done in a workmanlike manner, meet the drawings and code, and that defects reported within a stated warranty period will be put right at no charge. Manufacturer warranties on materials and equipment pass to the owner. 12. Substantial completion and handover. Define substantial completion, the point when the owner can use the property, and final completion when all remaining items on a punch list are done. Payment and warranty periods often key off these dates. 13. Limitation of liability. Where the law allows, cap the contractor's total liability and exclude indirect losses. This is heavily negotiated and must stay within what construction law in the jurisdiction permits. 14. Termination. State how either side can end the contract, for cause such as non payment or serious default, or for convenience, and how work done and materials ordered are paid for on termination. 15. Dispute resolution and governing law. Name the governing law and set out a dispute process, often negotiation then mediation or arbitration, which is common in construction. ## Common mistakes to avoid The biggest mistake is a scope that relies on verbal understanding instead of clear drawings and specifications. The second is no written change order process, which lets cost and time drift with every site decision. Others include a payment schedule that pays ahead of work done, no retention, missing or inadequate insurance, no clear completion definition, and ignoring local licensing and lien rules. Fix these and a build is far more likely to finish on budget and on time. ## From a signed contract to a managed project Writing a strong contract is step one. The harder part is tracking the signed version, the change orders, the payment valuations, the retention release and the warranty period across a long project with many documents and subcontractors. When these live in scattered files and email, money and deadlines slip.
