Detached and backyard ADU construction in Fullerton.

A detached ADU is a complete small home on the same lot as the main house. We help owners turn the backyard idea into a site-built project with a clear footprint, utility plan, construction route, and scope.

01 · Lot fit

Place the home where the property can carry it.

The first sketch should respond to lot lines, existing buildings, easements, grade, drainage, trees, fire access, privacy, and the way the main home uses the yard.

A larger floor plan can reduce usable outdoor space or create a difficult utility route. We compare those tradeoffs before the layout becomes expensive to change.

02 · A complete small home

Structure, enclosure, systems, and finishes all count.

Site-built construction includes foundation, framing, roofing, exterior walls, windows, plumbing, electrical, heating and cooling, ventilation, insulation, drywall, cabinets, fixtures, finishes, and exterior connections.

The proposal also needs excavation, utility trenches, drainage, access protection, inspections, and restoration. Those parts should not appear late as surprises.

03 · Construction plan

Design the route as carefully as the rooms.

Crews need a safe path for demolition, soil removal, concrete, framing material, equipment, and daily cleanup. Tight side yards may change equipment and labor assumptions.

During planning, decide how the household keeps access, privacy, parking, and essential services while work is underway.

04 · Owner decisions

Set priorities before finish selections multiply.

Talk through long-term use, bedroom count, storage, laundry, accessibility, daylight, outdoor space, and maintenance. Then establish finish allowances that match those priorities.

A clear selection schedule keeps late decisions from interrupting inspections or ordering.
