Litchfield Park, Arizona has adopted: Arizona has NO statewide mandatory building code floor for general construction — code adoption is a per-city/county authority under state enabling statutes (e.g., A.R.S. Title 9 for municipalities). The City of Litchfield Park runs its own Building Safety Department, independently adopts and administers its own construction codes, and does not defer permitting to Maricopa County.

Functionally yes, though not as a separate application form. Tenant improvement work is billed under its own dedicated per-square-foot fee lines in the Citywide Fee Schedule (Office/Mercantile and Vanilla Shell at $20/sq ft, Restaurant/Medical at $40/sq ft) -- distinct from the 80%-of-Valuation-Chart fee for new shell construction -- and the City's Building Permit Questions and Answers page publishes its own, faster review timeframe (5-10 business days) for tenant improvement versus new commercial shells (15-20 business days).
