Most renovation work in unincorporated Maricopa County requires building permits. Structural changes, electrical, plumbing, mechanical, and roofing work all need permits. Cosmetic work like painting and flooring does not require permits. Apply through the Maricopa County Planning and Development Department.
Under Maricopa County's adopted building code, permits are required for renovations involving: structural alterations (removing or modifying load-bearing walls), electrical work (new circuits, panel upgrades, rewiring), plumbing modifications (adding fixtures, re-piping), HVAC installation or replacement, roofing replacement or re-roofing, window or door replacements that alter structural openings, additions of any size, and converting non-habitable space (garage, utility room) to habitable space. Work exempt from permits includes: painting, wallpapering, installing floor covering, replacing fixtures in kind (same location, same type), and minor maintenance repairs. The permit process involves plan submittal to the Planning and Development Department (online or in person), plan review, permit issuance, inspections during work, and final inspection. The department uses an online permit portal (apps.pnd.maricopa.gov) for submitting applications and scheduling inspections.
Unpermitted renovation work may result in stop-work orders, required after-the-fact permits with additional fees, and potential fines. The county may deny certificate of occupancy for major renovations without permits.
