What is an ADU?
An Accessory Dwelling Unit (ADU) is a secondary, self-contained housing unit located on the same lot as a primary residence. ADUs are commonly referred to as granny flats, in-law suites, or backyard homes. In California, ADUs are allowed in most residential zones, offering a flexible solution for increasing housing density without the need for large-scale developments.
The popularity of ADUs has surged, driven by the state’s housing crisis, as well as the growing need for affordable housing and multigenerational living solutions. If you’re planning to build an ADU in California, one of the first steps is obtaining a permit. This is where ADU permit application templates can simplify the process.
Why ADU Permits Matter
Before diving into the ADU application process, it’s important to understand why permits are necessary. Building an ADU without the proper permits can result in significant legal, financial, and safety issues. A permitted ADU ensures that the unit meets local building codes, zoning regulations, and safety standards, which benefits both you and the broader community.
Key benefits of building a permitted ADU include:
Legal Compliance: Avoid fines or the possibility of having the unit demolished.
Property Value: A permitted ADU increases your home’s value and makes it more marketable.
Rental Income: Renting a legal ADU provides a consistent income stream.
Neighborhood Integrity: Permits ensure that the ADU meets community standards, enhancing neighborhood quality.
