Types of ADUs We Build in Thousand Oaks
Detached ADUs
A standalone structure built separately from your main home, perfect for a guest house, rental unit, or multigenerational living space. Detached ADUs in Thousand Oaks can be built up to 1,200 square feet and offer complete privacy for occupants. Popular in Newbury Park and Westlake Village where lot sizes accommodate a separate structure.
Attached ADUs
An addition connected directly to your existing Thousand Oaks home, sharing at least one wall. Attached ADUs are an efficient way to add living space without building an entirely separate structure. They integrate seamlessly with your home's existing architecture and utilities, making them a cost-effective choice for Conejo Valley homeowners.
Garage Conversions
Transform your existing garage into a fully functional living space. Garage conversions are one of the most cost-effective ADU options for Thousand Oaks homeowners because the basic structure is already in place. We handle structural upgrades, insulation, plumbing, electrical, and finishing. A popular choice in Lynn Ranch and Wildwood neighborhoods.
Junior ADUs
Built within the existing footprint of your Thousand Oaks home, junior ADUs are capped at 500 square feet and must include a separate entrance and a small cooking facility. They are an affordable way to create an independent living space without expanding your home's footprint, ideal for homeowners throughout the Conejo Valley.

ADU Regulations in Thousand Oaks
Understanding local ADU regulations is essential before starting your project. Here are key rules under California ADU law and City of Thousand Oaks requirements that apply to ADU construction in the Conejo Valley.
Maximum Size: 1,200 Square Feet
Detached ADUs in Thousand Oaks can be built up to 1,200 square feet on most standard residential lots. Attached ADUs may be limited to 50 percent of the existing living area or 1,200 square feet, whichever is less. Junior ADUs are capped at 500 square feet and must be built within the existing footprint of the home.
Setback Requirements
ADUs in Thousand Oaks must maintain a minimum 4-foot setback from side and rear property lines. Front setback requirements follow standard zoning rules for your lot. Garage conversions that use the existing footprint may be exempt from some setback requirements under California state ADU law.
No Owner-Occupancy Requirement
Under current California state law, there is no owner-occupancy requirement for most ADUs in Thousand Oaks. This means you do not have to live on the property to rent out your ADU, making it a flexible investment option for property owners in Newbury Park, Westlake Village, Lynn Ranch, Wildwood, and across the Conejo Valley.
Parking Requirements
California state ADU law has significantly relaxed parking requirements for accessory dwelling units. Replacement parking is generally not required when converting a garage to an ADU, and new ADUs located within a half mile of public transit may be exempt from additional parking requirements. Our team evaluates your specific situation during the design phase.
Local Permits and Inspections
All ADU construction in Thousand Oaks requires building permits from the City of Thousand Oaks Community Development Department. The process includes plan check review, building permits, and multiple inspections throughout construction. Safeway Construction manages the entire permitting process from application through final sign-off, ensuring full compliance with both city codes and California ADU law.
