Number of Units Allowed As is required by state law, each property developed or proposed to be developed with a single- family residence will be permitted to construct both an ADU and a JADU. This could result, potentially, in a single-family property with up to three units. Moreover, properties developed with multi -family residences are permitted to convert existing non - habitable space within the building, including garages, into ADUs in the amount up to 25 percent the number of existing units on the site. For example, a multi -family residence with 20 units may convert existing non -habitable space up to a total of five ADUs. In addition to converting existing non -habitable space within the building, two detached ADUs are also permitted, either through the conversion of existing detached non -habitable space or new construction. The proposed ordinance will reflect these changes to state law. Size of Units Santa Ana's prior ordinance limited ADUs to a minimum of 220 square feet and a maximum of 750 square feet in size; units could not exceed 50 percent the size of the primary residence, and a maximum of one bedroom. The size and bedroom limitations were established as a response to community concerns related to overcrowding, the scale of ADUs in comparison to smaller homes that are found in the city, and exacerbation of on -street parking issues that many neighborhoods are experiencing if multiple bedrooms were permitted.
