Questions to Ask Before Signing a Commercial Tenant Improvement Contract in Tempe

Before you sign anything for a commercial build-out or tenant improvement (TI) project in Tempe, the contract sitting in front of you deserves a hard look—because what's missing from the paperwork is often just as costly as what's in it.

Verify Licensing, Bonding, and Insurance First

Arizona's Registrar of Contractors (ROC) requires all commercial contractors to hold an active license before pulling permits or breaking ground. Before the conversation goes any further:

• Confirm the ROC license number and verify it at roc.az.gov—check that the license class matches your project type (B-1 General Commercial is common for TI work).
• Ask for a certificate of insurance showing general liability (typically $1M per occurrence minimum for commercial work) and workers' compensation coverage.
• Confirm bonding status. Arizona's ROC bond requirements are relatively modest, but your landlord or lender may require higher bond amounts.
• Check for any open complaints or disciplinary actions on the ROC portal—a five-minute search can save months of headaches.

Tempe's commercial corridor—Mill Avenue, the Elliot Road Tech Zone, downtown mixed-use—attracts a lot of out-of-state contractors chasing growth. Don't assume an impressive portfolio means Arizona licensing is in order.

Understand the Scope of Work in Detail

Vague scope language is where TI projects go sideways. Push for specifics:

Ask These Scope Questions

1. What exactly is included—and excluded? Demolition, MEP (mechanical, electrical, plumbing), fire suppression, data cabling, signage blocking, and ADA upgrades each need to be clearly listed or explicitly excluded.
2. Who handles permit filing? In Tempe, commercial permits go through the Community Development Department. Clarify whether the contractor pulls permits, who pays permit fees, and who manages plan review responses.
3. What are the landlord's TI allowance conditions? Many Tempe landlords cap reimbursable work to base building systems and require their own approved contractor list. Your contract should align with the lease's TI exhibit.
4. Are allowances or unit prices used for uncertain items? If the contractor bids an "allowance" for flooring or fixtures, get a clear process for approving overruns before work starts.

Nail Down the Payment Structure

Arizona's lien laws give contractors, subcontractors, and suppliers real power to place a mechanic's lien on a property if they go unpaid—even if you've already paid your general contractor. Before signing:

Always request conditional lien waivers from the GC and major subcontractors at each draw, and an unconditional final lien waiver before releasing the last payment.

Clarify the Timeline and Weather/Season Realities

Tempe summers are brutal. Interior TI work can proceed through June–September, but if any part of your project involves exterior work, roofing, concrete pours, or deliveries, ask how the contractor plans around:

• Heat delays: Early morning start times and material staging are common mitigation strategies.
• Monsoon season (roughly June 15–September 30): Flash flooding, dust storms, and afternoon downpours can halt exterior work and damage unsealed materials. Ask who bears the cost of weather delays.
• Supply chain lead times: HVAC equipment, specialty glass, and electrical gear can have 12–20+ week lead times. Your schedule should reflect realistic procurement windows, not optimistic ones.

Get the substantial completion date in writing with a clear definition of what "substantial completion" means for your space (typically a certificate of occupancy or Tempe's equivalent sign-off).

Ask About Subcontractors and Material Sourcing

A GC's quality is only as good as their subs. Request:

• A list of major subcontractors (electrical, plumbing, HVAC/mechanical) and verify their ROC licenses independently.
• Confirmation of who is responsible if a subcontractor walks off the job or goes out of business mid-project.
• Where key materials are sourced and whether substitutions require your written approval.

Understand TPT and Tax Obligations

Arizona's Transaction Privilege Tax (TPT) applies to construction contracts, but the way it's structured matters. For commercial projects, contractors typically pay TPT on materials and pass costs through—but some contracts shift TPT liability to the owner in ambiguous ways. Have your CPA or attorney review the tax language before you sign, especially if you're a business with your own TPT license.

Dispute Resolution and Warranty Terms

• Warranty: A one-year workmanship warranty is a baseline minimum; some contractors offer two years on labor. Manufacturer warranties on materials are separate—confirm how claims are handled.
• Dispute resolution clause: Many contracts default to arbitration, which can be faster and cheaper than litigation but limits your appeal options. Know what you're agreeing to.
• Termination for convenience: Understand what it costs you to exit the contract if the project stalls or the relationship breaks down.

Signing a TI contract in Tempe without working through these questions is how businesses end up over budget, behind schedule, or stuck in a half-finished space. Take the time to search local commercial construction pros who know Tempe's permitting process and landlord requirements, and browse Saguaro List's commercial construction directory to compare vetted options. A well-negotiated contract protects everyone—and good contractors welcome the detailed conversation.
