Questions to Ask Before Signing a General Contractor Contract in Tucson

Signing a general contractor contract in Tucson is one of the biggest financial commitments most homeowners make, and the details buried in that document can cost you thousands if you're not prepared. Asking the right questions before you put pen to paper protects your project, your budget, and your sanity through every phase of construction.

Verify Licensing and Insurance First

Arizona's Registrar of Contractors (ROC) requires general contractors to hold a valid license before performing work. This is non-negotiable — and easy to check for free on the ROC's public website.

Ask the contractor:

• What is your ROC license number, and can I verify it online?
• Do you carry general liability insurance, and what is the coverage limit?
• Do you carry workers' compensation for all employees and subcontractors on my job?

Request certificates of insurance directly from the insurer, not just a copy the contractor printed. If a worker is injured on your Tucson property and coverage lapses, you could be liable. Liability coverage for residential projects typically ranges from $500,000 to $2 million — ask what their policy covers and confirm it's current.

Understand the Scope of Work in Writing

Vague contracts are the root of most contractor disputes. Every material, task, and finish should be described specifically.

• What exactly is included in the quoted price? Permits, demolition, cleanup, and haul-away are often left out of initial bids.
• What is explicitly excluded? "Allowances" for tile or fixtures can balloon if you choose options above the base price.
• Who pulls the permits? In Tucson, the contractor should pull all required City of Tucson Development Services permits. If they suggest you pull permits yourself, treat that as a red flag.
• Which subcontractors will be used, and are they licensed? Ask for their ROC numbers too.

Also clarify Arizona TPT (Transaction Privilege Tax) responsibilities. Depending on the contract structure, your contractor may owe TPT on materials — make sure the contract states clearly who is responsible so you aren't surprised by a tax bill later.

Nail Down the Payment Schedule

Never pay more than roughly 10–15% upfront for a standard residential project. A contract that demands 50% before work begins is a warning sign. A reasonable payment structure ties milestones to completed, verifiable work.

Ask specifically:

• Is there a retainage clause that holds back a percentage until final inspection passes?
• What payment methods are accepted, and will I get receipts tied to each milestone?
• What triggers each payment — calendar date, or confirmed completion?

Ask About Timeline, Weather, and Monsoon Season

Tucson's climate directly affects construction schedules. Summers regularly exceed 105°F, slowing outdoor labor and concrete curing. Monsoon season (roughly June 15 through September 30) brings sudden heavy rains that can pause excavation, roofing, and exterior finish work.

Questions to ask:

• How does your schedule account for Tucson's summer heat and monsoon season?
• What happens to the timeline and budget if weather causes delays?
• Is there a liquidated damages clause if the project runs significantly over schedule?

A contractor who has worked in the Tucson area should discuss these realities upfront — not act surprised when you bring them up.

Clarify Change Order Procedures

Scope creep is one of the most common ways projects go over budget. Before signing, understand exactly how changes are handled.

• All change orders should be in writing, signed by both parties, with cost and schedule impacts documented before work begins.
• Ask: Who authorizes change orders on your side, and who on mine?
• Ask: What markup percentage does the contractor charge on change order materials and labor? (Typical ranges are 10–20%, but this varies.)

A contractor who resists a formal change order process is a contractor who may surprise you with verbal charges later.

Review Dispute Resolution and Warranty Terms

Even good projects can have disagreements. Read the contract's dispute resolution clause carefully.

• Does it require binding arbitration (waiving your right to a jury trial)?
• Is there a lien waiver process so subcontractors can't file liens on your property after you've already paid the general contractor?
• What is the workmanship warranty period? One year is a common minimum; some contractors offer longer.
• Arizona's ROC also handles complaints and can order corrective work — make sure the contract doesn't try to waive your right to file an ROC complaint.

If your project involves HOA approval — common in many Tucson-area master-planned and desert communities — ask whether the contractor has experience submitting architectural review applications and whether any delays awaiting HOA sign-off are addressed in the schedule.

Do Your Homework on the Contractor

Before the meeting even happens, use a local Tucson business directory to research who operates in your area, read reviews, and compare credentials. When you're ready to reach out to vetted pros, search for licensed general contractors near you to build a shortlist worth interviewing.

Check the ROC's complaint history for each contractor you're considering — a few resolved complaints on a long track record is different from a pattern of unresolved issues.

A well-written contract protects both parties, sets clear expectations, and gives you recourse if things go sideways. Take the time to ask every question on this list before signing — a contractor confident in their work will welcome the conversation, not dodge it.
