Understanding ADUs and JADUs in California
An accessory dwelling unit (ADU) is an auxiliary housing unit built in addition to a primary dwelling. ADUs comply with local and state requirements, making them true dwelling units that can be legally occupied and rented. In 2017, California adopted statewide legislation legalizing ADUs across all cities as part of an effort to address the state's affordable housing crisis. Subsequent ordinances have continued to make it easier than ever to build an ADU, with the goal of increasing rental supply statewide.
ADU eligibility and building requirements vary by city and county, but the majority of residentially zoned lots — including single-family homes and multifamily properties — are generally allowed at least one ADU. As part of their consultation process, ADU Builder LA assesses each property's ADU feasibility so homeowners are fully informed of their options.
There are two main classifications of accessory dwelling units in California: ADUs and JADUs (Junior Accessory Dwelling Units). JADUs were introduced under California's AB 2406 and can often be built in addition to a standard ADU. Key distinctions include:
- JADUs have a maximum size of 500 square feet
- JADUs must be contained within the existing envelope of the primary dwelling unit
- JADUs allow for an "efficiency" kitchen rather than a full standard kitchen
- JADUs require owner occupancy; ADUs may or may not depending on jurisdiction
- JADUs have no parking requirement; ADU parking requirements vary by condition
Common JADU examples include garage conversions and bedroom conversions that offer independent living space. If a space meets JADU requirements, it can be an excellent option to maximize a property's overall ADU count.
Types of ADU Builds Offered
Within these two classifications, there are multiple build types that ADU Builder LA works with as an experienced ADU builder:
- Detached ADUs — Standalone structures with no shared walls with the primary dwelling. This includes backyard cottages, granny flats, back houses, in-law suites, and detached garage conversions. These can be new ground-up construction or conversions of existing detached structures.
- Attached ADUs — Units attached to or created from the existing primary dwelling. Examples include attached garage conversion projects, basement conversions, bedroom or living room conversions, and home additions. These may qualify as JADUs if they meet the applicable requirements.
As a licensed JADU contractor and in-law suite builder, ADU Builder LA manages the entire construction process, including all permitting requirements on behalf of their clients. A fully permitted ADU is essential for lawful habitation and rental use.
ADUs are considered an affordable development type because they do not require purchasing land or making major infrastructure investments. They can increase property value, generate rental income to offset mortgage payments, and provide flexible living arrangements for families — whether for college students, young adults, or aging relatives. They also serve as home offices, creative studios, or additional space for growing families seeking a cost-effective solution without relocating.
