What we build across San Diego County
Design, permits and construction under one roof — so no part of your project waits on a company that doesn't work for you.
Garage Conversions
Turn an unused, glorified storage unit into a livable room or a backyard rental. Attached, detached or integral garages — we convert all three.

Read moreADU & Backyard Homes
An accessory dwelling unit is a second, self-contained home on your existing lot — kitchen, bathroom, its own entrance. Since California's 2016 reforms and AB 68 in 2019, most of the red tape that used to block them is gone.
- Built for rental income, multi-generational living, or a starter home for family
- Studio through two-bedroom layouts
- Adds long-term property value that a remodel alone rarely matches
- Roughly half the cost of buying a second single-family home in San Diego
Garage Conversions
Most garages in San Diego are glorified storage units. Converting one is usually the fastest and cheapest route to an ADU, because the foundation, walls and roof already exist.
- Attached, detached and integral garages all convert
- Full ADU conversions with kitchen and bathroom, or a single room
- Over-the-garage apartments where the lot allows a second story
- Home gyms, offices and guest rooms where a full ADU is not the goal
Granny Flats
A granny flat keeps a parent close without anyone losing their independence — the arrangement that makes multi-generational living work instead of straining.
- Single-story, step-free layouts designed for aging in place
- Wider doorways and accessible bathrooms where needed
- Studio through two-bedroom
- Also known as a mother-in-law suite, accessory home or backyard home
Backyard Offices & Studios
A real workspace forty steps from your back door — properly insulated, properly wired, and quiet enough to take a call in. Also the right build for a gym, a studio or a home theater.
- Fully permitted and built to code, not a shed
- Insulated and climate-controlled for year-round use
- Wired for the power and network a working office actually needs
- Art studios, home gyms, theaters and gaming rooms
3D Design & Permitting
We measure your home and digitize it into full-color 3D renderings you can walk through virtually. You change the design on screen — not after the framing is up.
- See and modify your ADU before construction starts
- We research what your specific neighborhood permits before designing
- We prepare the plans and walk them through city approval ourselves
- Plan review and permit fees handled, inspections coordinated
Not sure which one fits your lot?
That's the normal starting point. San Diego County doesn't allow every type of ADU in every neighborhood, so the first thing we do is find out what yours permits.
