Detached ADU guest house with pool at dusk

We design and build primary-suite additions, kitchen expansions, family rooms and second-story additions. Rooflines, windows and finishes are planned to work with the existing house.

An ADU can provide space for family or a rental unit. We handle feasibility, California's ADU requirements, local permitting and utilities through final inspection.

Planning your project in Pleasanton

We offer remodeling services throughout Pleasanton, from downtown cottages to Ruby Hill homes.

The local housing includes downtown Victorians and Craftsman cottages alongside 1980s–2000s estates. Some post-war properties have space for an addition or ADU. We assess the lot and any existing garage during the feasibility review.

We serve Pleasanton, including Ruby Hill, Downtown Pleasanton, Vintage Hills and Birdland. Project planning here accounts for a downtown historic district with design review, plus large estate parcels east of town. We assess foundations, drainage and space on the lot when planning an addition or detached unit.

Permits and inspections in Pleasanton

Permits for work in Pleasanton go through the City of Pleasanton Building and Safety Division.

Frequently asked questions

Are ADUs legal in Pleasanton?

Yes — ADUs are legal in Pleasanton. California law requires cities to allow ADUs on most residential lots, and Pleasanton processes them under those state rules. We confirm setbacks, size limits and utility requirements for your specific parcel during the free feasibility visit.

What does an ADU cost to build?

It varies with size, site and finish level — a garage conversion is a different project than a detached new build. We price it in a written scope after walking your property, and financing options are available.

How long does an addition take?

Design and permitting typically run 2–4 months depending on the city; construction runs 3–6 months for most additions and detached ADUs. We provide a written schedule and keep you updated weekly.
