Forbes has marked 2020 as "The Year of the ADU" (ADU meaning; accessory dwelling unit). The increased demand for low-cost homes has coincided with changes in state regulations and improvements in construction technology, making it simpler for homeowners to develop detached structures and multi-family dwelling units.

Similarly, ADUs have been adopted by San Antonio, a thriving city in Texas, as a way to increase housing alternatives and meet the needs of its booming population. To help you build an ADU easily, we have discussed ADU in San Antonio's associated laws and costs below.

Santa Ana ADU Requirements

The City of Santa Ana ADU requirements ensure responsible and sustainable ADU development. These rules specify the conditions for setting up and using ADUs within city borders. To prevent any legal complications and guarantee compliance, citizens and property owners must be aware of these regulations. The principal laws comprise:

2. Occupancy

Santa Ana ADU requirements put occupancy restrictions on ADUs. Typically, only one ADU is permitted per lot, and the combined occupancy of the primary residence and the ADU must meet local occupancy requirements.

The owner must live in the primary residence or the ADU, and the property must be rezoned to allow more than one dwelling unit if the owner does not reside there.

3. Size

ADUs must be larger than 1,600 square feet or 50% of the primary residence's total living space, whichever is less.

Any property, regardless of the size of the primary residence, is permitted to have an accessory dwelling unit (ADU) that is at least 800 square feet in size.
