What should be in a renovation contract?

Here's an uncomfortable fact about the one-page contract your contractor handed you: it isn't short because renovation is simple. It's short because every clause it leaves out defaults in his favor. Ambiguity about scope favors whoever does the work. Ambiguity about schedule favors whoever controls the schedule. Ambiguity about payment favors whoever's asking for money.

The contract is the one moment you can shape the entire project while shaping it is still free. So let's go through what a contract written for your benefit contains — clause by clause, in plain English, with what each one is protecting you from.

Scope of work: what exactly am I buying?

This is the most important section and the most commonly butchered. “Remodel kitchen per discussion” is not a scope of work — it's a future argument with a signature line.

A real scope describes the work specifically enough that a stranger could check it: which rooms, which walls, what gets demolished, what gets installed, and to what specification. Materials pinned down by brand, model, grade, or an agreed allowance — “tile” and “the tile we looked at” are different universes of cost, and guess which one gets installed when the contract just says “tile.” The scope should also say what's excluded (haul-away? permits? painting after drywall repair?) and attach the drawings or plans by reference if any exist. A useful habit: after every product-selection conversation, email the contractor a one-line confirmation with the model or specification you agreed on, and keep the thread. If it was discussed but never written anywhere, assume for planning purposes that it isn't in the price.

Allowances deserve one extra sentence of respect: an allowance is a placeholder budget for something not yet selected (“$4,000 allowance for countertops”). They're legitimate — but a bid stuffed with lowball allowances is a low price that isn't real, and the difference lands on you at selection time. Every allowance should be realistic and clearly labeled.

Price and payment terms: where does the money stand?

The contract should state the total price and what kind of price it is. Fixed price means the number is the number, and the contractor bears ordinary cost surprises. Cost-plus (materials plus a fee or percentage) shifts risk to you and demands open books — workable for professionals, dangerous for a first-time homeowner. Time-and-materials on an open-ended basis is how small jobs become large invoices. If you take anything other than a fixed price, understand exactly what you're agreeing to absorb.

Then the payment schedule — the clause that determines who holds the leverage for the whole project. Payments should be tied to completed milestones, not calendar dates; the deposit should be modest, not the “half up front” that so many homeowners mistakenly assume is normal; and the final payment should be big enough to matter, released only at genuine completion. Building that schedule is its own craft, covered step by step in the payment schedule guide — but the contract is where it must live. A payment schedule that exists only in conversation doesn't exist.

Schedule: when does it start, and when is it late?

Three dates belong in writing: when work starts, when it will be substantially complete, and — the one everyone forgets — what happens if it isn't. Without a completion commitment, “three months” is a vibe, and vibes have a documented tendency to become years once your project is competing with newer, fresher deposits elsewhere.

You won't always get penalty terms — liquidated-damages clauses (a set amount per day of unexcused delay) are common in commercial work and resisted in residential — but you can almost always get real dates, a definition of substantial completion, and a clause requiring written notice of delays with reasons. Even that much transforms your position later: a contractor who must explain delays in writing behaves differently from one who can simply stop showing up. Pair the schedule with a clause on continuity of work — that the contractor will pursue the project with reasonable diligence — so prolonged unexplained absence becomes a documentable breach rather than a mood.

Change orders: how do changes happen?

Something will change — the house will surprise everyone, or you'll upgrade something once the walls are open. The contract's job is to make sure changes happen through a process instead of a series of driveway conversations.

The clause is simple: no change to scope, price, or schedule is effective unless documented in a written change order signed by both parties before the changed work is performed. That sentence is the whole discipline — and it protects both sides, which is exactly how to sell it to a reluctant contractor. What it prevents is the end-of-project “extras” invoice, the memory contest about who approved what, and the mid-project money ambush (which has its own survival guide: what to do when a contractor asks for more money mid-project).

Insurance and licensing: whose disaster is an accident?

Two coverages matter, and they protect against different catastrophes. General liability covers damage the contractor's work does — the fire, the flood into your neighbor's unit. Workers' compensation covers injuries to the people working on your property; without it, a roofer who falls may look to you, and homeowners policies vary in how much of that they'll absorb. The contract should state that the contractor carries both, at stated coverage amounts, and — this is the part that separates paper from reality — that he'll provide certificates of insurance direct from the insurer naming you as certificate holder, so you learn if coverage lapses. A photocopied certificate from last year proves what was true last year.

Add the license: the contractor's license number (if your state licenses the trade) belongs on the face of the contract, along with a representation that it's current. Verifying it takes five minutes on your state board's site — a standard part of vetting any contractor before signing.

Lien waivers: how do I keep unpaid subs off my title?

Here's the clause almost no homeowner knows to ask for, protecting against the risk almost no homeowner knows exists: if your general contractor doesn't pay his subcontractors or suppliers, they can generally record a mechanic's lien against your home — even though you paid the GC in full. The full mechanics (and the state-by-state variation) are laid out in the mechanic's lien guide; the contract is where you install the defense.

The clause: each progress payment is conditioned on receipt of signed lien waivers — from the contractor and from the subcontractors and suppliers whose work that payment covers — and final payment is conditioned on final waivers from everyone. Add a requirement that the GC provide and update a list of all subs and suppliers on the project. A contractor who pays his people signs this without blinking. A contractor who balks has just told you where your money goes.

Termination: how does this end if it goes wrong?

Nobody signs a contract planning to invoke the termination clause, which is why contractors' form contracts so often have a one-sided one — or none. Yours should say: you may terminate for cause (abandonment, persistent failure to perform, loss of license or insurance) after written notice and a short cure period; what you owe on termination is the value of work properly completed, not the whole contract price; and how disputes get resolved. Read that last part carefully in his draft — arbitration clauses, venue selections, and attorney-fee provisions decide how expensive your worst-case scenario is, and they're routinely written to make pursuing the contractor impractical.

Why it matters: when a project is abandoned, the difference between a contract with a real termination clause and one without is the difference between executing a procedure and improvising a legal theory.

Warranties: what happens when the tile cracks next spring?

The contract should state what the contractor warrants and for how long: workmanship warranted against defects for a stated period (commonly a year or more — get it in writing, whatever it is), manufacturer warranties on materials passed through to you with the registration paperwork, and a commitment to return and correct warranty defects at no charge within a stated response time. Also confirm nothing in the contract purports to waive warranties your state's law gives you automatically — some contractor forms try. “I stand behind my work” is a lovely sentence; the warranty clause is what it looks like when it's true.

The permits clause — and the two-word test

One more that earns its place: the contract should say who obtains and pays for permits, and it should be the contractor, in his name. A contractor who wants to skip permits, or asks you to pull an owner's permit for work he's performing, is shifting inspection risk and liability onto you — and often signaling something about his license status.

And when you've read the whole document, apply the two-word test: for each clause, ask “says who?” Who decides the work is complete? Who decides a delay was excusable? Who decides the change was included in scope? Every place the answer is “the contractor decides” is a place the contract needs work. You're not aiming for a document that punishes him — a fair contract protects both sides. You're aiming for a document where nothing important is decided by whoever's holding the hammer.
