San Diego Garage Conversion ADU FAQs
Do I have to replace the parking spots I lose?
This is the #1 question. In most San Diego “Transit Priority Areas” (which cover a huge portion of the city), no. State law (AB 68) prohibits cities from requiring replacement parking when a garage is converted to an ADU. We will verify your specific address to confirm you are exempt.
What do you do with the sloped garage floor?
Garages are sloped towards the door for drainage. You can’t live on a slope. We have two methods: 1) Sleeper System: Building a wood subfloor above the concrete (great for running pipes underneath). 2) Self-Leveling Concrete: Pouring a new layer to flatten the surface. We choose the method based on your ceiling height.
Can I keep the garage door for aesthetics?
Technically yes, but it’s inefficient. Glass garage doors are popular for an “industrial look,” but they are terrible insulators. We recommend replacing the door with a framed wall and high-efficiency windows for better temperature control and privacy, unless you are aiming for an indoor/outdoor “party room” vibe.
Is a garage conversion considered a JADU or a standard ADU?
It can be either! If it’s under 500 sq. ft. and you add an efficiency kitchen, it can be permitted as a JADU (often faster/cheaper fees). If it’s a larger 2-car garage (600+ sq. ft.) or includes a full kitchen, it will be permitted as a Standard Attached ADU. We help you choose the classification that fits your goals.
Where do I put the water heater and laundry?
These are often already in the garage. We usually relocate them to a dedicated “utility closet” within the new ADU layout or move them to an exterior tankless system to save precious interior square footage.
My garage has no windows. How do you bring in natural light?
Habitable rooms require natural light and ventilation (typically 8% of the floor area) by code. We don’t just add a lamp; we cut into the existing exterior walls to frame new, energy-efficient windows. We install structural headers to support the roof load above these new openings. If privacy is a concern (e.g., the wall faces a neighbor), we often install Velux skylights or solar tubes to flood the unit with daylight from above without compromising privacy.
