ADUs ARE A
CORE FOCUS
Accessory Dwelling Units are a core focus — not a secondary offering. We build ADUs designed for long-term value — whether that means rental income, multigenerational living, or property expansion in high-demand Peninsula and East Bay neighborhoods.
As an experienced ADU builder Bay Area homeowners rely on, Mendez & Son's Construction designs and builds detached ADUs, attached ADUs, garage conversions, in-law units, and rental-ready backyard cottages.
California has made ADUs more accessible, but that doesn't mean they're simple. Each city has zoning rules, setback requirements, utility tie-in rules, and inspection sequences. If paperwork is mishandled, projects stall.
We handle permitting, plan coordination, and city communication from the beginning.
Real Problems ADUs Solve
- Aging parents need privacy but proximity
- Adult children moving back home
- Long-term rental income
- Property value expansion
- Flexible guest or office space
Full permit management from submission through final inspection.

Consultation

SERVING
THE BAY
AREA
Homes in these areas involve complex permitting, high property values, and high expectations. Execution must match that environment.
We work throughout the Peninsula, South Bay, and East Bay — with city-specific permit knowledge for each jurisdiction. All Areas We Serve
AN ADU IS
MORE THAN
EXTRA SPACE
For many homeowners, an ADU is a long-term asset. Regional housing demand remains strong. Having a secondary unit increases flexibility in ways a standard remodel cannot.
If you're evaluating whether an ADU makes sense for your property, we can review zoning and feasibility during your consultation.
Rental Income
A permitted secondary unit provides stable long-term income in a strong SF Bay Area rental market.
Multigenerational
Independence with proximity — aging parents, adult children, caregivers, without relocation.
Property Value
A permitted ADU adds a legal functional unit — a meaningful difference at resale.
Future Flexibility
Private office, studio, downsizing option. Changes how the property is used for decades.
UPFRONT CAPITAL
SHOULDN'T STALL
YOUR PROJECT
Across the Peninsula and East Bay, construction costs are significant. Many homeowners have strong equity but prefer not to liquidate investments or tie up cash reserves.
We help clients access renovation financing when needed. This is a practical tool — not a promotional tactic. For qualified homeowners, applications are straightforward and approvals move quickly.
If you prefer to self-fund, that's fine. If you want financing options, we can walk you through them.
“Upfront capital should not be the reason a project sits on hold.”
