Browse Permit-Ready ADU Plans

Looking for the perfect ADU floor plan for your property? At GatherADU, we design and permit modern Accessory Dwelling Units that fit California's zoning rules and your lifestyle. Whether you want a garage conversion, detached ADU, or attached in-law suite, our team helps you choose a layout that maximizes space, comfort, and value.

Our pre-designed ADU floor plans range from studio layouts under 400 sq ft to spacious two-bedroom backyard homes over 1,000 sq ft. Every plan includes smart storage, open-concept living areas, and energy-efficient design.

Plans are Title 24 compliant and ready for fast permit approval in cities like Los Angeles, Burbank, Glendale, Pasadena, and the San Fernando Valley.

Garage Conversion & Small ADU Floor Plans

Turning an existing garage into a livable unit is one of the fastest and most affordable ways to add housing. Our garage conversion floor plans start at 350 sq ft and include a full kitchen, bathroom, and laundry space. These layouts are optimized for natural light and privacy - perfect for rental income or family use.

We also offer compact studio and one-bedroom ADU floor plans that meet California's state standards for parking exemptions, setbacks, and height limits. Each small ADU plan can be customized to match your main house design and local building code requirements.

Detached ADU Floor Plans

If you have a larger lot, our detached ADU designs offer complete independence and flexibility. Popular options include 500 sq ft, 650 sq ft, and 800 sq ft floor plans, each featuring a full kitchen, bath, and open-living concept. We tailor each plan to your property's orientation, lot shape, and city code, ensuring the best possible use of space and sunlight.

Our detached ADUs are ideal for long-term rentals, guest houses, or multi-generational living. With proper planning, you can add a second home that increases property value by 20-30% while generating $2,000-$3,500+ monthly rent.

Our team manages every step - from site analysis and architectural drawings to Title 24, structural plans, and permit submission.
