This page is a practical guide to buying land in Gilbert, Arizona. It explains the questions you need to answer before you make an offer, from zoning and utilities to septic, wells, and accessory dwelling units. Every lot is different, so treat this as your starting checklist and then verify the specifics for any parcel you are serious about.
Start with zoning and buildability
Not every vacant lot can become the home you picture. Gilbert's Land Development Code assigns every parcel to a zoning district, and each district carries its own rules on minimum lot size, setbacks, and permitted uses. Some lots are fully buildable for a single-family home; others are constrained by size, shape, or access. The first step in any land purchase is confirming what the zoning actually allows, and the Town of Gilbert's planning and development services office can confirm the district for a specific parcel.
Utilities: water and sewer matter most
In Gilbert's developed areas, water and wastewater are Town services, and the Town manages water meters and connection fees. Before you buy, find out whether water lines reach the property line and what the connection and tap fees would be. If the parcel sits outside the Town's sewer service area, the picture changes and the plan will likely involve a septic system instead.
Septic systems and private wells
Where sewer is not available, an on-site septic system is the norm, and that means county and state requirements come into play, typically Maricopa County Environmental Services and the state's water quality rules. Private wells are legal in many areas as well, but they are regulated and must meet setback requirements from septic systems and other features. If a listing description says "well and septic," you should know those are systems you will be responsible for installing, operating, and someday maintaining, and both can carry meaningful costs.
HOAs, CC&Rs, and planned communities
A large share of Gilbert is master-planned, and much of the remaining land sits inside communities governed by homeowners associations. If the lot you are buying is subject to CC&Rs, those documents can dictate your home's style, size, colors, setbacks, and even landscaping, so read them before you commit. Land with an HOA often includes its own utilities and common areas, which is convenient, but it also means approvals for your build.
ADUs: what you can build on your lot
Accessory dwelling units, sometimes called casitas or ADUs, have become a hot topic for land buyers. Arizona state law now requires municipalities like Gilbert to allow at least one attached and one detached ADU on single-family lots as a permitted use, with the details, including size limits, setbacks, and permit requirements, set by the community. If you are buying land with an eye toward a guest house, a rental unit, or multi-generational living, confirm the current rules for the specific lot before you build your budget around it.
The rest of your due diligence list
Beyond zoning and utilities, a serious land buyer should check the survey and property lines, any easements or access rights, flood zone designation, soils and drainage, and whether the lot has any liens or title issues. Land is sold "as is" in a way houses rarely are, which is why title work and a quiet, walk-the-property inspection matter double.
Why a land-savvy agent helps
Land transactions are a different animal from home purchases. An agent who has done them before knows to ask about entitlements, lot splits, well and septic feasibility, and the hidden costs that only show up after closing. I have spent decades with buyers across the East Valley, including those building from the ground up, and I can bring that experience to your land search, along with introductions to the surveyors, engineers, and builders you will need.
