Built for San Mateo homes

Every project starts with the real constraints of the home: layout, structure, utilities, permitting, access, finish level, and how your household needs to live during construction.

  • Garage conversion, detached, attached, and junior ADU planning
  • Feasibility review for access, utilities, layout, and site constraints
  • Kitchenette, bath, HVAC, electrical, and privacy coordination
  • Permit documentation support and inspection sequencing
  • Interior finishes that match the home instead of feeling temporary

Service area

Based in San Mateo, Lussoro serves homeowners across San Mateo County, the Peninsula, San Francisco, San Jose, and surrounding Bay Area communities.

Questions homeowners ask

What type of ADU is fastest to build?

Garage conversions and junior ADUs are often faster than detached units, but feasibility depends on existing structure, utilities, access, and code requirements.

Can an ADU be used for family or rental income?

Yes. Many San Mateo homeowners build ADUs for parents, adult children, guests, office use, or rental flexibility.

Does Lussoro handle the construction team?

Yes. We coordinate the trades, schedule, site work, finishes, and owner communication throughout the build.
