How much should I pay upfront for construction?

Most states cap homeowner deposits between 10% and 33% of the contract price. Tie every additional payment to a completed, inspected milestone — never pay ahead of work performed.

Construction Contract Template: A Homeowner's Guide

Q: What should a construction contract include?

A homeowner-safe construction contract should define the scope of work, total price, milestone payment schedule, start and substantial-completion dates, change-order process, lien waivers, insurance, warranty period, and a dispute-resolution clause.

Q: Is a construction contract template legally binding?

Yes — once both parties sign and consideration is exchanged, a written construction contract is enforceable. A template gives you a strong starting point, but high-value or complex jobs should still be reviewed by an attorney licensed in your state.

Before you hand over a deposit, your contract is the single biggest piece of leverage you have. This guide walks through every clause a homeowner-safe construction agreement should include — plus a sample template you can adapt for renovations, additions, and new builds.

Why your contract matters more than the bid

The lowest bid usually wins the job, but the contract decides who wins the disputes. Vague scope, lump-sum deposits, and "we'll figure it out later" change orders are the three most common reasons remodels blow past budget. A clear contract eliminates all three.

The template below covers the clauses required in most US states and reflects the structure we use at BuildTrust AI when we review contracts for homeowners.

The 10 essential clauses

1.Parties and project address

Full legal names of the homeowner(s) and the contractor's licensed business entity, the contractor's license number and state, and the exact property address where the work will be performed.

2.Detailed scope of work

A line-by-line description of what is and isn't included — demolition, framing, finishes, fixtures, brand and model numbers for appliances, paint colors, and any allowances. If a detail isn't written here, assume it isn't included.

3.Total contract price and allowances

A single total price, broken out by trade or phase, with every allowance (tile, lighting, plumbing fixtures) called out as a dollar figure. Anything over the allowance becomes a change order.

4.Milestone payment schedule

Tie payments to completed, inspected work — not calendar dates. A homeowner-safe schedule looks like: 10% deposit, 20% at rough framing, 20% at mechanical rough-in, 20% at drywall, 20% at substantial completion, 10% retainage held 30 days after final inspection.

5.Start date and substantial-completion date

Both dates in writing, plus per-day liquidated damages if the contractor blows past completion without an approved extension. Without a deadline, there's no deadline.

6.Change-order process

No verbal change orders. Every change requires a written description, a price, and signatures from both parties before work begins. This single clause prevents most cost overruns.

7.Lien waivers

Conditional lien waiver from the GC and every subcontractor for each progress payment, and an unconditional final waiver before the last check is released. Skipping this is how homeowners end up paying twice.

8.Insurance and licensing

Proof of general liability (at least $1M), workers' compensation, and an active state license — attached as exhibits and verified before work starts.

9.Warranty

At minimum: 1 year on workmanship, manufacturer warranties on all materials passed through to you in writing. Many states require longer minimums for structural work — check yours.

10.Dispute resolution

Mediation first, then binding arbitration in your county, with the prevailing party recovering attorney's fees. Avoid clauses that force arbitration in the contractor's home state.

  Homeowner: [FULL LEGAL NAME], residing at [PROPERTY ADDRESS] ("Owner")
  Contractor: [BUSINESS LEGAL NAME], License #[NUMBER] ([STATE]) ("Contractor")

1. SCOPE OF WORK
   Contractor shall furnish all labor, materials, equipment, and permits to
   perform the work described in Exhibit A (Scope of Work and Specifications)
   at the property located at [PROPERTY ADDRESS].

2. CONTRACT PRICE
   Total fixed price: $[AMOUNT], inclusive of all allowances listed in
   Exhibit B. Any work outside the Scope requires a signed Change Order

3. PAYMENT SCHEDULE

   3.3 Mechanical, electrical, plumbing rough-in complete & inspected: 20%
   3.4 Drywall complete: 20%
   3.5 Substantial completion: 20%
   3.6 Retainage released 30 days after final inspection: 10%

   Each progress payment is conditioned on (a) the corresponding milestone
   being complete and inspected, and (b) delivery of a conditional lien
   waiver from Contractor and all subcontractors and suppliers paid from
   the previous draw.

   Liquidated damages of $[AMOUNT]/day apply for each day past
   substantial completion not excused by a written extension.

5. PERMITS & CODE COMPLIANCE
   Contractor shall pull all required permits and perform all work in
   compliance with applicable building codes. Copies of permits and
   inspection reports shall be provided to Owner.

6. CHANGE ORDERS
   No change to the Scope or Contract Price is effective unless documented
   in a written Change Order signed by both parties before the changed
   work begins. Verbal changes are not binding.

7. LIEN WAIVERS
   Contractor shall deliver a conditional lien waiver with each progress
   payment request and an unconditional final lien waiver from itself and
   all subcontractors before the final payment is released.

8. INSURANCE
   Contractor shall maintain General Liability insurance of not less than
   $1,000,000 per occurrence and Workers' Compensation as required by
   state law, naming Owner as additional insured. Certificates shall be
   attached as Exhibit C.

9. WARRANTY
   Contractor warrants all workmanship for one (1) year from substantial
   completion. All manufacturer warranties on materials shall be assigned
   to Owner in writing.

10. DISPUTE RESOLUTION
    The parties shall first attempt mediation in [COUNTY, STATE]. If
    unresolved within 30 days, disputes shall be resolved by binding
    arbitration in [COUNTY, STATE] under the AAA Construction Rules. The
    prevailing party is entitled to reasonable attorney's fees and costs.

11. TERMINATION
    Either party may terminate for material breach after 10 days' written
    notice and opportunity to cure. On termination, Owner shall pay for
    work satisfactorily completed through the termination date.

12. ENTIRE AGREEMENT
    This Agreement, including Exhibits A–C, is the entire agreement and
    may only be modified by a writing signed by both parties.

OWNER: ____________________________  DATE: __________
CONTRACTOR: _______________________  DATE: __________

Five red flags to walk away from

Demands more than 33% upfront, or a deposit before any materials are ordered.
Refuses to put change orders in writing — “we'll just track it as we go.”
No license number, no proof of insurance, or a license registered in a different name.
Vague scope ("kitchen remodel as discussed") with no fixture brands, finishes, or allowances.
Arbitration clause that forces disputes into the contractor's home state or waives your right to sue.
