Commercial Tenant Improvement (TI) Permit in Lake Havasu City, Arizona
Required for build-out or renovation of an existing commercial tenant space in Lake Havasu City. Uses the SAME 'New Commercial Structures, Tenant Improvements, and Multi-Family Projects' development-review process and the same five discipline plan-acceptance checklists as new commercial construction (checking 'Tenant Improvement' instead of 'New Construction'), but the City's own published plan-review timeframes process Tenant Improvements on a distinct, faster 25-business-day track (vs. 35 business days for new Multi-Family and Commercial construction), and the Stormwater checklist substitutes a materially lighter requirements set for TI projects with no land disturbance.

When you need this permit
- Same 5-step Development Review / Permit Process as new commercial construction (Pre-Application Meeting, Completeness Verification, concurrent Plan Review by Planning/Building/Engineering/Fire/Stormwater, Corrections, Permit Issuance) -- there is no separate, stand-alone TI process or TI-specific application form; the applicant checks 'Tenant Improvement' rather than 'New Construction' on each discipline's Plan Acceptance Criteria checklist
- The Pre-Application - Commercial & Multi-Family form's Site Specifics section captures 'Tenant Space Sq. Ft.' as a distinct field from 'Total Building Sq. Ft.', 'Proposed use', and 'Prior use'
- Where the TI scope involves NO land disturbance, the Stormwater Plan Acceptance Criteria substitutes a dedicated, lighter requirements set in place of the full New Development stormwater package: a Solid Waste Management Plan (trash/debris/construction material management/storage), Storm Drain Inlet Protection (streets, alleys, parking lots, drainage grates, washes), a Spill Response Plan & Emergency Contact Information (oils, grease, fuels, chemicals), and a Slurry Containment plan (cement, tile/stone cutting, stucco, plaster, paint washout containment)
- Automatic fire sprinklers are required on all commercial occupancies, including TI scope; sprinkler and fire-alarm plans require a minimum NICET III (or Fire Protection Engineer) stamp, except a 13D system, which may be designed by a non-registrant
- Mohave County Health Department approval is required if the tenant's proposed use trips a Health-regulated category (food establishment; public/semi-public pool or spa; pet shop/kennel/grooming except veterinary clinics; public accommodation; RV/mobile home park; school building)
- Registrant requirement: every plan sheet must be stamped by an Arizona registrant, except projects exempt under A.R.S. § 32-144
- No permit is issued until the general contractor's City business license number and State contractor's license number are on file Contractor

Tips
- The City's published plan-review timeframes list Tenant Improvements as a distinct 25-business-day category -- 10 business days faster than the 35-business-day Multi-Family and Commercial (new construction) track -- plus a 7-10 business day completeness-verification review that runs before the plan-review clock starts, the same as for new commercial construction.
- There is no separate, stand-alone TI application form -- this permit uses the SAME Permit and Zoning Clearance application and the SAME five discipline Plan Acceptance Criteria checklists (Building, Planning, Engineering, Fire, Stormwater) as new commercial construction. Check 'Tenant Improvement' rather than 'New Construction' on each checklist.
- If the TI scope involves no land disturbance, confirm with the Stormwater reviewer that the lighter TI-specific requirements list (Solid Waste Management Plan, Storm Drain Inlet Protection, Spill Response Plan, Slurry Containment) applies instead of the full civil-drainage/SWPPP package required for new development.
- GAP NOT FULLY RESOLVED: the same fee-schedule access limitation noted on this file's Commercial Building Permit entry applies here -- no independently confirmed, TI-specific flat-dollar fee (distinct from the general valuation-based S-033/S-034 mechanism) could be verified in this research pass (2026-08-01).
