Answer the casita and middle housing questions Tucson homeowners are typing, with Tucson's own rules
Between October 2024 and December 2025, Tucson rewrote two sets of rules for what a residential lot may hold. Ordinance No. 12131, adopted on October 22, 2024, allows two casitas on a parcel with one house. On December 16, 2025, Mayor and Council adopted Ordinance No. 12219, the Middle Housing code amendment, by six votes to one, and the City says that as of January 1, 2026 duplexes, triplexes, fourplexes, townhomes and cottage courts may be developed across most of Tucson. Homeowners now search for a builder who knows these rules, and the builder who states them clearly on a website is the one they find.
Tucson's casita rules are its own. The city's casita worksheet, dated May 19, 2025, allows a casita of up to 650 square feet, or 75 percent of the main house up to 1,000 square feet. The side and rear setbacks are 5 feet at minimum, and a casita may not stand in the front yard. The height limit is the one for a single-family house in the same zone, which the worksheet gives as "generally 25 ft". The worksheet also says "There are no parking requirements for casitas" and requires a cool roof on new structures. A parcel of more than one acre may hold a third casita when one is deed-restricted for households earning 80 percent of the area median income or less.
The Building Permits Survey of the U.S. Census Bureau counted 3,592 single-family homes permitted in the Tucson metro area in 2025, against 4,150 in 2024, and 24 two-unit buildings, against 40. These counts were made before January 1, 2026, the date the City gives for the Middle Housing amendment. The Bureau's figures for the city of Tucson alone are imputed in full, because the city reported no months in 2024 or 2025, so this page quotes the metro area. For a Tucson builder the rule is new, and a page that explains what the amendment allows answers a question that the amendment itself created.
A Tucson page cannot be a copy of a Phoenix page, because the figures differ. Tucson allows a casita of 650 square feet, or 75 percent of the main house up to 1,000 square feet; Phoenix allows 1,000 square feet or 75 percent of the main house on a lot of up to 10,000 square feet. Of the 80 small builder websites we read in Arizona and Florida on September 29, 2026, 14 linked no blog or news section from the homepage or the menu and 14 showed a footer year before 2026. One note was written per site, so both counts are minimums.

You can build two casitas on a Tucson parcel that has one existing house, according to the City of Tucson casita worksheet dated May 19, 2025. A parcel of more than one acre may hold a third casita when one of them is deed-restricted for households earning 80 percent of the area median income or less. A parcel with a duplex may hold one casita. The rules come from Ordinance No. 12131, adopted on October 22, 2024.
A casita in Tucson can be up to 650 square feet, or 75 percent of the size of the main house up to a limit of 1,000 square feet, according to the City of Tucson casita worksheet dated May 19, 2025. The height limit is the one that applies to a single-family house in the same zone, which the worksheet gives as "generally 25 ft". The side and rear setbacks are 5 feet at minimum.
A casita in Tucson needs no parking space of its own. The City of Tucson casita worksheet dated May 19, 2025 states "There are no parking requirements for casitas". The same worksheet requires a cool roof on new structures, sets the side and rear setbacks at a minimum of 5 feet, and does not allow a casita in the front yard. An older summary on the city's website still mentions one parking space; the worksheet is the current statement.
Duplexes, triplexes and fourplexes are allowed across Tucson, except in rural residential areas, under Ordinance No. 12219, which Mayor and Council adopted on December 16, 2025 by a vote of 6 to 1. The City says the change applies from January 1, 2026. In the R-1 zone the ordinance allows four homes on a lot of 6,000 square feet, with a height of 25 feet, and it also covers townhomes and cottage courts.
Tucson's casita rules set a smaller base size and a greater height than Phoenix's. Tucson allows 650 square feet, or 75 percent of the main house up to 1,000 square feet, with the height of a single-family house in the zone, given as "generally 25 ft". Phoenix allows 1,000 square feet or 75 percent of the main house on a lot of up to 10,000 square feet, and 15 feet of height for a detached unit unless a use permit allows more.
The Tucson metro area permitted 3,592 single-family homes, 24 two-unit buildings and no buildings of three or four units in 2025, according to the Building Permits Survey of the U.S. Census Bureau. In 2024 the figures were 4,150, 40 and 7. The Bureau's figures for the city of Tucson alone are imputed in full, because the city reported no months in either year.
Plan review for a new home or a casita in Tucson has a performance goal of 10 business days. The City of Tucson sorts permits into review lanes, and its Fast Lane, with that goal, covers a new residential dwelling, a model home from a template and a residential ADU or casita. The Standard Lane, which covers residential additions and alterations, has a goal of 20 business days. A builder's website can state both figures with the date it read them.
