Land and lots around Tucson
Vacant lots and acreage, from in-town infill to open desert. With land, the questions matter more than the photos.
Before you buy land near Tucson, confirm four things: water (city service or a well), wastewater (sewer or septic), legal access, and whether the lot sits in a flood zone.
Arizona treats a domestic well that pumps 35 gallons per minute or less as an exempt well. You still file a Notice of Intent to Drill with the Arizona Department of Water Resources first, and a licensed well driller does the work.

How I’d check a piece of land
Start with the four questions
Water, wastewater, access and flood zone. A great view doesn’t help if one of these is a dead end.
Check with the right office
Zoning depends on where the land is: the City of Tucson, Marana, Oro Valley, Sahuarita or Pima County. Each has its own rules.
Give yourself time to look
Your offer should allow time for due diligence, like a survey, a septic feasibility check and quotes to bring in utilities.
Where to look things up
Free public resources I check before writing an offer on land:
- Flood zones: the FEMA Flood Map Service Center, plus the Pima County Regional Flood Control District for unincorporated areas.
- Wells: the Arizona Department of Water Resources well rules and drilling steps.
- Septic: the Pima County Department of Environmental Quality permits onsite wastewater systems.
- Electric service: depending on the area, Tucson Electric Power or Trico Electric Cooperative. Ask what it costs to bring power to the lot.
Common questions
Can I drill a well on land near Tucson?
Often, yes. Arizona treats a domestic well that pumps 35 gallons per minute or less as an exempt well. You still file a Notice of Intent to Drill with the Arizona Department of Water Resources, and a licensed well driller does the work. Confirm the details with ADWR before you buy.
How do I know if a lot is in a flood zone?
Check FEMA’s Flood Map Service Center, and for unincorporated areas, the Pima County Regional Flood Control District. A lot outside a mapped zone can still see runoff during monsoon storms, so walk it and look at the washes nearby.
Do I need a septic system?
If the lot can’t connect to sewer, yes. In Pima County, onsite wastewater (septic) systems are permitted through the Pima County Department of Environmental Quality, and soil conditions affect what you can install.
Who decides what I can build?
The jurisdiction where the land sits: the City of Tucson, the towns of Marana, Oro Valley and Sahuarita, or Pima County for unincorporated land. I can help you find the right office and the right questions to ask.
