MLS tracks this two ways. "Guest house" is a yes-or-no field the listing agent checks. "Guest quarters with a separate entrance" also catches attached suites, including 14 Lennar homes for sale from about $515,000 to $850,000. The listings below use the second field and include homes for sale, pending and sold.
| Setup | Where you see it in Phoenix |
|---|---|
| Back guest house on an older lot | Central Phoenix historic neighborhoods, many homes built from the 1910s to the 1950s |
| Guest house on an estate lot | Arcadia and the Camelback corridor |
| Builder suite with its own entrance | Lennar new builds in west Phoenix (Western Garden) and north Phoenix (Middle Vistas) |
| Full ADU with its own kitchen | Any of the above, if permitted under the City's ADU rules |

From the last three years of guest-house listings:
City ADU rules. Phoenix allows up to two ADUs on a lot with one single-family home, and a third in some cases. Each ADU can be up to 75% of the main house's gross floor area, capped at 1,000 square feet on lots up to 10,000 square feet and 3,000 square feet on larger lots. The City Council approved its current ADU ordinance changes in late 2024 to follow state law.
HOA. Phoenix's own ADU page tells owners to check HOA rules on accessory structures. Under the 2024 state law, an HOA can keep an ADU ban already in its CC&Rs.
Old permits. A back house on a 1930s lot may be older than the city's records for it. We check the permit history and the electric, water and sewer setup before you count it as living space or rental income.
Historic districts. If the home is in a designated historic district, changes to the casita's exterior may need extra review. We confirm the district status for each address.
Say you are moving from Chicago for a job in central Phoenix, and your mother is coming too. Two households would mean a mortgage plus her rent. In the suburbs, guest-house homes under $700,000 are scarce: only 12 each listed in Gilbert and Queen Creek in the last three years. Phoenix had 452, many on older central lots with a back house. The trade-off is age and upkeep, so we price in the roof, the sewer line and the casita's permit before you write an offer.
We moved to Arizona from the Detroit area in 2008 and have closed more than 700 home sales since. Twenty of our 29 sales from September 2025 to August 2026 were families relocating to Arizona. If you are weighing a central Phoenix casita against a newer one in Gilbert, Mesa or Queen Creek, where we have lived, we can show you both. See our track record.
