Tips

  • Minor projects — service clearance, water heater replacement, A/C relocation/replacement, window replacement, sewer line repair outside the public right-of-way, utilities outside the public right-of-way, and residential solar/PV installation — use the county's dedicated Over-the-Counter Submittal Guide & Application rather than the full Residential/Commercial Permit Guide process.
  • Unlike unincorporated Maricopa County (which exempts water heater replacement done to manufacturer spec), unincorporated Yuma County's own Building Safety FAQ confirms water heater replacement DOES require a permit here.
  • For electric or gas clearance (turning utilities back on after they've been off), commercial projects must use a licensed contractor, and a building inspector must verify the work before clearance is granted. Contractor
