Custom ADU Builder in Placer County
Add a second home to the property you already own. Design, permits and build handled by one local team. As a licensed design-build ADU contractor, we take your accessory dwelling unit from first sketch through final inspection — design, permits, and construction under one roof. From rental units to backyard offices and golf-simulator suites, every accessory dwelling unit we build is tailored to how you’ll actually use it.

Your ADU options
What we build
Detached ADU — up to 1,200 sq ft. A standalone second home on your lot, with its own entrance, kitchen and bath. The most private option and the strongest for rental income or multigenerational living.
Attached ADU. Shares a wall with your main house, which keeps foundation and utility costs down. Often the most budget-efficient route to a full second dwelling.
Garage conversion. Turns square footage you already have into a legal, permitted living space. Typically the fastest path to rental income, since the shell already exists.
Junior ADU — up to 500 sq ft. Built within your home’s existing footprint. Ideal for an in-law suite, a home office, or a first step into an ADU without reshaping the lot.
Purpose-built leisure space. Golf simulators, home gyms, theatre rooms and studios — designed around ceiling height, power and sound from the first concept rather than retrofitted after.
Guest suites and rental units. Finished, code-compliant dwellings up to 1,200 sq ft — engineered around how you actually live.
Purpose-built leisure space. Golf simulators, gyms and theaters — ceiling height and power planned from day one.

What our clients say
ADU questions, answered
How big can my ADU be?
In Placer County, a detached ADU can generally be built up to 1,200 sq ft, and most parcels allow up to three dwellings total. We confirm exactly what your property allows during your free site assessment.
Do you handle permits and engineering?
Yes — all site planning, structural engineering, permits, and inspections are handled by our licensed team for a fully turnkey build. You never chase paperwork.
Can I add a kitchen, bathroom, or bar?
Absolutely. We plan the plumbing and electrical for full kitchens, baths, wet bars, or a golf-sim setup — whatever the space is built for, it’s designed in from day one.
Does an ADU add value, and can I rent it later?
Yes. As a permitted, legal dwelling it adds real value and stays flexible — a guest suite today, an in-law unit or long-term rental tomorrow. (ADUs can’t be sold separately from the main home, and rentals under 30 days aren’t permitted.)
