A raw piece of Arizona land can look like a blank canvas. Open sky, room to spread out, no neighbors in sight. That part is real. But land that looks simple on the surface can carry a lot of costs underneath it, and the buyers who find out about those costs after closing are the ones who call us frustrated. Here is what to actually check before you sign.
Water: where it comes from and what it costs to get there
This is the first thing to figure out in Arizona, full stop. Is there a municipal water line you can connect to, and how far away is it? Extending a water main is not cheap — it can run anywhere from a few thousand dollars to well over $50,000 depending on distance and the municipality involved. If you are outside a service area, you are looking at a well. Well drilling in central Arizona typically runs $15,000 to $40,000 depending on depth, and there is no guarantee you will hit water at a depth that makes economic sense. Some areas have depth minimums set by the state. Get clarity on the water situation before you fall in love with a parcel.
Septic versus sewer
Same idea. If municipal sewer service is not available, you are installing a septic system, which adds $8,000 to $20,000 or more to your project depending on the soil type and the required system design. Certain soil conditions require engineered systems that cost significantly more than a standard install. A perc test — percolation test — tells you how the soil handles drainage. It is worth doing before you buy, not after.
Easements and setbacks
An easement is someone else's legal right to use a portion of your property — often for utilities, drainage, or road access. Easements do not always show up obviously on a listing, but they show up on a title report and a survey. A drainage easement running through the middle of your lot might not stop you from building, but it will absolutely change where you can build. Setback requirements — the minimum distances a structure must sit from property lines, roads, and other features — can further shrink a lot that looked generous on paper. Always pull the title report and review the plat before you make an offer.
Soil reports and what bad soil costs
Arizona has a lot of expansive soils — meaning soils that swell when wet and shrink when dry. That movement is hard on foundations. A geotechnical report, sometimes called a geotech or soils report, tells you what is in the ground and what kind of foundation engineering the site requires. On a good site, the report confirms what everyone hoped. On a challenging site, it might require a more expensive foundation system that adds real money to the build. That information is worth having before you are committed to the land.
Road access
Can you get to the property on a paved road, or does the access involve a dirt road? If it is a private road shared with neighbors, who is responsible for maintaining it? If it is an unimproved road on county land, the county may or may not maintain it depending on classification. Lenders care about this. So do buyers who want to get groceries delivered in July without destroying their car. Check the road situation and, if you are in a rural area, ask the county directly about road maintenance responsibility.
HOA and CC&Rs
If the land is within a subdivision or a community with deed restrictions, you need to read the CC&Rs — covenants, conditions, and restrictions — before you buy. These can govern everything from minimum square footage to exterior materials to the color of your front door. Some restrictions are reasonable. Others are genuinely limiting. Know what you are agreeing to before you close, because they run with the land and they do not care what the listing agent told you verbally.
The real cost of a "cheap" lot
A lot listed at $40,000 with no utilities, a well required, bad soils, and a two-mile private dirt road is not a $40,000 lot. It is a $40,000 lot with $120,000 in site work in front of it. That is not necessarily a reason to walk away — sometimes those parcels are still the right move — but you need the real number, not just the listing price. Total cost of a buildable site includes every dollar you spend before the foundation is poured.
Millhouse has a land broker on the team specifically to catch this stuff early. We look at land before our clients make offers, not after. That conversation costs nothing and has saved people from some genuinely expensive mistakes.
