We hired CADNEST DESIGN to design the plans for our ADU. Working with CADNEST DESIGN was a great experience. They worked through the design process to make sure that the ADU floor plan included everything we wanted. They are very responsible and professional in the work that they produce. I highly recommend hiring CADNEST DESIGN for your projects. More...

How can someone tell if their Garage is suitable for conversion?
Is my garage suitable for conversion?
Zoning District:
The property must be in a residential or mixed-use zone that allows dwellings.
Most single-family (R-1) and multifamily (R-2, R-3, etc.) zones qualify.
Allowed Use:
A garage conversion is treated as an ADU or JADU (Accessory or Junior Accessory Dwelling Unit). Nearly all California cities must allow at least one ADU on a single-family lot, including garage conversions.
Parking & Replacement Rules:
No Replacement Parking Required
Under Gov. Code §65852.2(a)(1)(D)(x)(I), if a garage, carport, or covered parking is converted into an ADU, replacement parking is not required. However, the site must still meet local driveway and street access requirements (e.g., fire department access width).
Setbacks & Lot Coverage:
Existing Structure Advantage:
A legally built existing garage may maintain its existing setbacks, even if it’s close to a property line.
(CA Gov. Code §65852.2(a)(1)(D)(vii))
Lot Coverage / FAR (Floor Area Ratio):
Most local agencies cannot apply lot coverage, FAR, or open space limits to prohibit an ADU smaller than 800 sq. ft., 16 ft high, and 4 ft side/rear setbacks.
Fire Separation:
If the garage is on or near the property line, walls may need to be upgraded to 1-hour fire-rated assemblies with no openings on that side.
Development Standards:
To be considered a habitable space under the California Building Code (CBC) and Title 24:
Ceiling height: Minimum 7 ft.
Natural light/ventilation: At least 8% of floor area in window glazing for light, 4% for ventilation.
Insulation & energy compliance: Must meet Title 24 energy standards.
Foundation: Existing slab must be structurally sound and moisture-protected.
Utility & Infrastructure Readiness:
Utility connections:
ADUs cannot be required to have separate utility connections or impact fees if they are converted from an existing space within the main dwelling or a garage (Gov. Code §65852.2(f)(2)).
Water & Sewer:
If plumbing is added, the connection to existing lines must comply with local health department and utility standards.
