What Is an Accessory Dwelling Unit (ADU)?
An Accessory Dwelling Unit (ADU) is an independent residential dwelling unit that has become increasingly popular among homeowners seeking additional living space without the need to purchase a new property. ADUs provide extra square footage within an existing lot and typically include one or two bedrooms, a kitchen, and a bathroom. They can serve a wide range of purposes — from a home office or guest house to a dedicated residence for aging parents or in-laws.
Over the last several years, Southern California has experienced a significant rise in demand for affordable housing, which has directly contributed to the growing popularity of ADU construction in Los Angeles. As a result, experienced ADU builders and ADU contractors have become essential partners for homeowners looking to maximize their property's potential.
The ADU Construction Process
ADU Builders guides clients through every stage of the construction process, from initial site visits and design planning to city permits, inspections, and final walkthroughs. Their process is structured and transparent:
- Initial Site Visit: They visit the property to discuss setbacks, model options, utility hookups, and eligibility. An estimate is provided based on the specific requirements of the project.
- Permits: As knowledgeable ADU contractors in Los Angeles, they understand California's ADU construction guidelines and assist clients in submitting design plans to the Department of Building & Safety. They also ensure compliance with ADU setback rules. Notably, any ADU under 750 sq. ft. is exempt from Impact Fees.
- Building the ADU or Garage Conversion: Whether it's a detached ADU, attached ADU, or garage conversion, they deliver tailored solutions that meet all space and code requirements.
- Final Inspection: Once construction is complete, a final walkthrough is conducted. Upon receiving the certificate of occupancy from the local municipality, the unit is ready for occupancy.
ADU Builders operates in full compliance with ADU building codes and ensures that all documentation — including site plans, permit applications, and construction drawings — is accurately prepared to minimize approval delays. Permit approval typically takes between 60 and 90 days when all documentation is in order.
Key setback rules for detached ADU construction in Los Angeles require a minimum of 10 ft. from the main building, 5 ft. from the nearest property lines, and 4 ft. from the rear and side of the lot.
Types of ADUs They Build
ADU Builders specializes in a variety of ADU types to suit different property layouts and homeowner needs:
- Detached ADU: A backyard cottage or standalone unit not connected to the main structure. Ideal for privacy and independent living, these are often easier to construct regardless of the condition of the main home.
- Attached ADU: Units connected to the main house, maximizing lot coverage. These may require fire-rated partitions between the ADU and the primary residence.
- Garage Conversion ADU: Converting unused garages or parking spaces into fully functional living units. This is one of the most cost-effective methods of adding an ADU to a property, making them a popular choice for garage conversion contractors.
- JADU (Junior Accessory Dwelling Unit): Smaller units with a maximum of 500 sq. ft., subject to fewer regulations. JADUs must be created from existing space within the primary structure and may share bathrooms with the main residence.
