Homes on 1+ Acre for Sale in Buckeye, AZ

Homes on an acre or more around Buckeye sit mostly on the rural edges: inside city limits on R1-43 and agricultural land, and just outside them in unincorporated Maricopa County areas such as Rainbow Valley, Palo Verde, Tonopah and Arlington. Expect wells or a mix of water providers, septic systems and room for animals or a shop.

I'm Terry Day with DeLex Realty. Buckeye is one of the largest cities in Arizona by land area, and most of its new growth comes as master-planned neighborhoods on standard lots. The acre lots are a different world. Two homes with the same Buckeye mailing address can sit under different rules, because one is inside the city and the other is on county land a mile away. Here is how I sort that out with buyers before they fall for a piece of land.

Where the acre lots are around Buckeye

Inside city limits. Buckeye covers close to 400 square miles, and its General Plan planning area is far larger than that. Within the city, large lots are found where the land is zoned R1-43 or AG (agricultural). The City's Development Code describes R1-43 as a district with limited agricultural, animal and ranching privileges that acts as a transition between farm land and denser neighborhoods. AG land is meant mainly for farming and ranching. The older Rural Residential (RR) district is now listed as obsolete, so you may still see it on older parcels, but no new land is being zoned that way.

Rainbow Valley. South of the Gila River, Rainbow Valley is mostly unincorporated Maricopa County land with multi-acre parcels and a lot of horse owners. It is outside Buckeye's city limits even though it sits next to the city. I wrote a full guide to Rainbow Valley homes and acreage if that area is on your list.

Palo Verde, Tonopah and Arlington. Palo Verde is a county island inside Buckeye's planning boundary, southwest of downtown along Old US 80. Arlington is farther out on Old US 80, and Tonopah is a rural community to the west, where voters turned down becoming a town in 2009. All three are unincorporated, so county zoning, county roads and private wells are common there.

Because the city and county lines jump around, I check the jurisdiction of every parcel on the Maricopa County Assessor's map before we look at zoning or animal rules. The search button above shows homes listed with a Buckeye city name and a lot of an acre or more, so it can include both city and county parcels.

What you can do with an acre in Buckeye

Animals. Under the City's code, domesticated farm animals are allowed in the AG district, and in the R1-43 and R1-18 districts on lots of at least half an acre, for noncommercial use. The code I reviewed does not set a simple number of horses per acre, so I ask the City about a specific lot. Chickens are limited to six with no roosters, kept in a roofed coop set back from the neighbor's line. County land follows county rules, and many subdivisions add their own HOA rules on top.

Shops and barns. In the R1-43, RR and AG districts, accessory buildings are not held to the usual maximum floor area, but they are capped at 22 feet tall and still count toward lot coverage. That is good news if you want a big garage, a hay barn or a workshop.

Guest units. Buckeye allows one attached and one detached accessory dwelling unit on a single-family lot. A lot of an acre or more can add one more detached unit if at least one of the units is deed-restricted as affordable. Each unit can be up to 75% of the main home's floor area, and an RV or mobile home cannot be used as one.

Water, wells and septic

Who provides the water. The City of Buckeye serves much of the city, and the City's utility page names EPCOR and Arizona Water Company as other providers in parts of Buckeye. The City also posts a water and sewer service area map, which I use to check a specific address. Many rural and county parcels are on a private well instead.

Private wells. In Arizona, a household well that pumps 35 gallons per minute or less is an exempt well. Drilling a new one takes a Notice of Intent filed with the Arizona Department of Water Resources (ADWR), and when a property with a well sells, the new owner files a change of ownership with ADWR. If a well is shared with neighbors, I want to see the written shared-well agreement.

The bigger water picture. In January 2023, ADWR released a groundwater model for the Hassayampa area west of Buckeye that showed more demand than supply over 100 years. Since then, new subdivisions there cannot get a new certificate of assured water supply based on local groundwater alone, while neighborhoods that already held certificates can keep building. The City says it has water for existing customers and growth that is already certified. This mostly affects new subdivisions, but it is worth understanding before you buy land you hope to split or build on.

Septic. Many acre homes use a septic system. Arizona requires a septic inspection within six months before the sale closes, and the buyer files a Notice of Transfer within 15 days after closing; in Maricopa County that is done through the county's online permit center. Inside city limits, a parcel needs a sewer determination, and if a sewer line reaches the property line, connection can be required.

Roads, floods and lot splits

Roads. Many rural roads are private dirt roads. The Maricopa County Department of Transportation says roads outside the county road system stay the owners' responsibility, and the county has no legal authority to grade or pave them. I ask who maintains the road to every property and whether there is a road maintenance agreement.

Floods. The Buckeye area has the Gila and Hassayampa rivers and many washes. The Flood Control District of Maricopa County handles floodplains for Buckeye and the county, and its online Floodplain Viewer and free flood hazard reports show whether a parcel is in a mapped zone. That affects where you can build and whether a lender will require flood insurance.

Lot splits. On county land, a lot split creates five or fewer parcels, each under 36 acres, and must still meet zoning; six or more parcels is a subdivision. Inside the city, Buckeye has its own Minor Subdivision process. Either way, I tell buyers not to count on splitting a lot until the City or County confirms it.

Riding and open space nearby

Skyline Regional Park, a City of Buckeye park on Watson Road in the White Tank Mountains, covers about 8,700 acres with roughly 20 miles of trails, and its trails are open to horseback riders (not the short accessible paths). Maricopa County's Buckeye Hills Regional Park covers about 4,453 acres for hiking and biking, and the county's horse staging areas are at White Tank Mountain and Estrella Mountain regional parks.

My checklist for a Buckeye acre home

• Is the parcel in the City of Buckeye or unincorporated Maricopa County, and what is the zoning?
• Water: City, EPCOR, Arizona Water Company, or a well? Is the well shared, and is the paperwork current with ADWR?
• Septic or sewer, and when was the septic last inspected and pumped?
• Who maintains the road, and is it paved?
• Any mapped flood zone or washes on the lot?
• HOA or deed restrictions on animals, sheds, RVs or guest units?
• Is the lot exactly an acre or more, or does the listing round up?

Questions buyers ask

Where can I find homes on an acre or more in Buckeye?
Most are on the rural edges, on R1-43 or agricultural land inside the city and in unincorporated areas such as Rainbow Valley, Palo Verde, Tonopah and Arlington. Many of those county areas still use Buckeye mailing addresses.

Can I keep horses on a Buckeye lot?
Often yes: the City allows farm animals in the AG district and in R1-43 and R1-18 on lots of at least half an acre, for noncommercial use. County parcels follow county rules, and HOA rules can be stricter, so I check each lot.

Do Buckeye acre homes have city water?
Some do and some do not. Depending on the address, water may come from the City of Buckeye, EPCOR, Arizona Water Company or a private well, so I look up the provider before you write an offer.

Can I build a guest house on an acre in Buckeye?
Usually you can add an accessory dwelling unit: Buckeye allows one attached and one detached unit, with an extra detached unit on lots of an acre or more if one is deed-restricted as affordable. Size limits and any HOA rules still apply.
