5 Common Mistakes in Tenant Improvement Projects (and How to Avoid Them in Phoenix)
When it’s time to prepare a commercial space for a new tenant, tenant improvements (TIs) can become costly if not planned and managed properly. From permitting delays to overlooked MEP requirements, the smallest oversight can impact your timeline, budget, and tenant satisfaction.
CMP General Contracting delivers full-service TI support across the Phoenix Metro—combining licensed general contracting and HVAC under one roof. Here are the five most common TI mistakes we see—and how to avoid them.
1) Starting Without a Clear Scope or Plan
Beginning demo before drawings and trade scopes are finalized leads to avoidable change orders. Confirm architectural plans, engineering, and trade details before mobilization.
CMP Tip: We build line-item scopes that cover demo, framing, HVAC/electrical, finishes, and inspections so everyone knows exactly what’s included.
2) Underestimating Permit Timelines
Each jurisdiction—Tempe, Phoenix, Scottsdale, Mesa—has its own review process. Missing documentation or unclear scopes can trigger re-review and slip move-in dates.
CMP Tip: We handle submissions and coordinate with city reviewers to keep the process moving and your schedule intact.
3) Overlooking Mechanical, Electrical & Plumbing (MEP) Updates
Older spaces may require HVAC upgrades, panel capacity increases, or plumbing changes to meet code and tenant loads. Discovering this late can be a budget killer.
CMP Tip: As a licensed General Contractor (ROC KB2-352581) and HVAC Contractor (ROC CR-39 332487), CMP evaluates MEP early to prevent surprises and downtime.
4) Ignoring Tenant-Specific Customizations
Kitchenettes, sound attenuation, data cabling, or special ventilation should be captured in preconstruction. Adding them mid-build drives cost and friction.
CMP Tip: We facilitate early coordination with your tenant so requirements are locked before demo.
5) Hiring Multiple Vendors Instead of One Full-Service Team
Coordinating separate HVAC, electrical, drywall, and finish contractors increases risk. Handoffs often cause delays and budget bleed.
