Ways to add a unit
More room for the main house
Before the build
Detached ADUs
What it covers: A new home of its own in the backyard: foundation, framing, utilities, kitchen, bath and finishes, built to the plans the city approved.
How it starts: With a look at the lot: setbacks, access for equipment and where the utility lines can run.
Good to know: Where the sewer line can reach often decides where the ADU goes, so it is checked before the design.
Garage conversions
What it covers: A garage turned into a legal living unit: insulation, windows, a raised and finished floor, a kitchenette and a bathroom.
How it starts: By checking the slab, the ceiling height and the parking rules before anything is designed.
Good to know: Converting an existing garage is often the quickest path to an ADU, because the walls and roof are already there.
Room additions
What it covers: New square footage on the main house: footings, framing, the roof tie-in, windows and finishes matched to the house.
How it starts: With drawings and the permit. Nothing is dug until the plans are approved.
Good to know: Matching the roofline and siding is what makes an addition look like it was always there.
Design & permits
What it covers: A site survey, floor plans, structural and energy calculations, and the permit set the city reviews.
How it starts: With what the household needs: a rental, a home for a parent, an office or a studio.
Good to know: Plan review can take more than one round; drawings that answer the city checklist up front save weeks.
Site prep & utilities
What it covers: Clearing, grading, trenching and new water, sewer and electrical lines run out to the new unit.
How it starts: By locating every existing line in the yard before the first trench is dug.
Good to know: An ADU often needs a larger electrical panel, so it is priced in from the start.
