For homeowners & contractors
Before you build or renovate: payment schedules, change orders, timelines and delays, warranties, liens and retainage, and dispute terms, in plain English with the change to ask for.

A construction or renovation contract governs a project where the costs are large, the timeline is uncertain, and the two sides often have very different expectations. The clauses that prevent disputes, on payment, changes, and delays, are the ones most often left vague until something goes wrong.
This guide covers the clauses that most often cause construction disputes: the payment schedule, change orders, timelines and delay terms, warranties, mechanics' liens and retainage, and how disagreements get resolved. For each one it explains the risk and the change to ask for.
It is general information, not legal advice. For a major build, a contract reviewed by a construction lawyer is cheap insurance against a project that goes sideways.
Watch how payments map to work completed. A schedule that pays most of the money early leaves you exposed if the contractor stops, underperforms, or walks off the job, you have paid for work you do not have.
Ask for: Ask to tie payments to completed, inspected milestones, keep a meaningful final payment until the work is done and signed off, and avoid large up-front deposits.
Changes are inevitable on a build, and they are where budgets explode. Without a written change-order process, verbal 'while we're at it' requests become disputed charges, or unpaid work, at the end.
Ask for: Ask for a written change-order process: every change priced and signed off before work proceeds, with no charges for changes not approved in writing.
A contract with no completion date, or one that excuses every delay, gives you no protection against a project that drags on. 'Substantial completion' without a date and a remedy is a recipe for an unfinished home.
Ask for: Ask for a completion date (or schedule), defined excusable delays only, and a remedy for unjustified delay such as liquidated damages or the right to terminate.
Check the workmanship warranty and how defects are handled after completion. A short or absent warranty, or one that excludes the most likely problems, leaves you paying to fix faulty work yourself.
Ask for: Ask for a written workmanship warranty of a reasonable length, clarity on what it covers, and a process for the contractor to return and fix defects.
If the contractor does not pay subcontractors or suppliers, they can place a mechanics' lien on your property, even though you paid the contractor. Retainage (holding back a percentage until completion) and lien waivers are your protection.
Ask for: Ask for lien waivers from subcontractors as you pay, a retainage held until final completion, and proof that subs and suppliers are being paid.
Confirm who carries insurance, who pulls permits, and how disputes are resolved. A contract that puts permit and insurance risk on you, or forces disputes into terms that favour the contractor, shifts cost and risk your way.
Ask for: Ask that the contractor carries liability and workers' comp insurance, is responsible for permits, and that dispute resolution (mediation/arbitration) is fair and mutual.
The single most protective principle in a construction contract is that payment follows completed, inspected work, never the other way around. Front-loaded schedules and large deposits transfer the risk to you: if the contractor stops, you are out money with an unfinished project and little leverage.
Keep a meaningful sum tied to final completion and sign-off, and release retainage only when the work, including the snag list, is genuinely done. ClauseShift flags the payment schedule and quotes it so you can see where your leverage sits.
A mechanics' lien is the clause homeowners least expect: a subcontractor the contractor failed to pay can attach a claim to your home even though you paid the contractor in full. Lien waivers and retainage are how you protect against paying twice.
Collect lien waivers as you make payments and hold retainage until the end. For a large project, this paperwork is not bureaucracy, it is the difference between a clean title and a fight.

Yes. It highlights how changes and payments are handled and surfaces when a written change-order process is absent, quoting the relevant clause.
It lets an unpaid subcontractor claim against your property even if you paid the contractor. Lien waivers and retainage protect you; the report flags whether they are present.
No. For a major build, use the report to get informed, then have a construction lawyer review the contract before you sign.
