Detached ADUs
The City of Thousand Oaks has the following size restrictions on Detached ADU's:
-
Up to 850 square feet for a studio or one-bedroom unit
-
Up to 1,000 square feet for a two-bedroom or larger unit
For your ideal ADU, consider these options:
-
A 400-600 square foot ADU works perfectly for a one-bedroom layout.
-
A 600-1,000 square foot ADU provides ample space for a single or two-story design, accommodating up to three bedrooms and multiple bathrooms.
Whether you're looking to maximize space for guests or create an independent living area, we'll help you design the perfect ADU to meet your needs and comply with local regulations.

Garage
Conversions
Converting a garage into an ADU is one of the most cost-effective options since the basic structure is already in place. However, most two-car garages in Thousand Oaks are typically only 300-400 square feet, limiting the available space.
​
For new detached ADUs, the city requires:
-
A 10-foot setback from the main house or garage (unless attached)
-
A 4-foot setback from the rear and side property lines
​
Garage conversions, however, do NOT need to meet these setback rules, making them a more flexible option for adding living space.
​
Our team can guide you through the process, whether you’re converting a garage or building a new ADU.
