Buying Near the Tucson Mountains: A West Side Checklist for Septic, Wells, Washes and Wildfire
What to verify before buying a west side or Tucson Mountains home in 85745 and nearby, from septic transfer inspections to wells, washes and access.
West side homes near the Tucson Mountains offer space and views, and they often come with systems a city lot does not have. Before you fall for the sunset, here is what to verify in writing during your inspection period.
Is the home on septic, and what does Pima County require?
Many homes outside city sewer use an on site wastewater system. Pima County requires a transfer of property inspection by a qualified inspector within six months before closing, with the report filed with the county, and the buyer files a notice of transfer after closing. Ask for the report early and read it, not just the pass line.
Who supplies the water?
Confirm whether the home is on a water company, a shared well, or a private well. For a well, ask for the Arizona Department of Water Resources registration, any shared well agreement, and a recent water quality and flow test. New wells are restricted inside the Tucson Active Management Area, so the existing well matters.
Are there washes, floodplain or access issues?
Check county floodplain maps, look for wash crossings on the route in, and confirm who maintains the road. Some streets are private or unpaved, and monsoon storms can close crossings. Also confirm the jurisdiction, because a Tucson mailing address does not always mean city rules apply.
What about wildfire and insurance?
Buffelgrass and dense brush raise fire risk near the mountains. Ask about defensible space, get insurance quotes during your inspection period rather than after, and confirm coverage is available at a price you can carry. Our Arizona inspection period guide explains the timeline for these checks.

Does Pima County require a septic inspection when a home sells?
Yes. A transfer of property inspection must be done within six months before closing and the report filed with the county.
