Full Breakdown
21 of the fire code's permit table. 3 places that marking next to the main service disconnect where it is visible from the point of operation. 2 requires roof access, pathways, and spacing sized so firefighters can reach the roof and move around the array, and for residential structures it caps each photovoltaic array at no more than 150 feet by 150 feet on either axis, with detached non-habitable Group U structures like carports, detached garages, and solar trellises exempted. 5 add roof-specific rules: hip-roof homes need two 3-foot-wide access pathways from eave to ridge, panels must sit at least 18 inches from a hip or valley when placed on both sides of it, and panels can be no higher than 3 feet below the ridge so the fire department can still vent smoke.
Violations & Fines
Installing solar panels without the required permit, or without the mandated DC marking and roof-access pathways, is enforced as a Fire Code violation under Section 9-37: the City issues a written notice of violation, and civil fines run from $50 to $2,500 per violation, with criminal violations carrying fines plus up to one year of incarceration. Section 9-40 caps civil sanctions at the maximum fine for a Class One misdemeanor, and an unresolved notice can be recorded against the property with the Maricopa County Recorder under Section 9-38.
