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.
Full permit management from submission through final inspection.

We review your goals, property, zoning considerations, and budget range. For ADUs, we discuss placement, access, utilities, and intended use.
Plans are developed with buildability in mind. Structural requirements, engineering, and sequencing are considered early — not after drawings are complete.
We coordinate submissions and revisions with the city. Local permitting can be detailed.We respond to plan check comments and keep the process moving.

Decisions are made by someone who understands framing, inspections, scheduling, and subcontractor coordination. You won't get passed between departments.
Structured project management systems. Clear estimates. Clear scopes. Defined phases. Documented communication. Construction is complex — organization reduces friction.
An ADU is a long-term asset decision. That means dedicated attention at every stage.
Every city in the greater San Francisco area has nuances — zoning interpretation, inspection pacing, submittal formats. We've worked across Peninsula, South Bay, and East Bay cities. That familiarity saves time.
You'll know what phase you're in. You'll know what's next. You'll know who to contact. No guessing. No surprises. Every project runs through documented communication via Buildertrend — nothing is lost in a text thread.
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
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.
A permitted secondary unit provides stable long-term income in a strong SF Bay Area rental market.
Independence with proximity — aging parents, adult children, caregivers, without relocation.
A permitted ADU adds a legal functional unit — a meaningful difference at resale.
Private office, studio, downsizing option. Changes how the property is used for decades.
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.”
