San Marino, Los Angeles County
ADU Construction in San Marino, CA
San Marino homeowners sit on some of the larger residential lots in the San Gabriel Valley, and that square footage creates real opportunity to add a detached ADU, convert a garage, or carve out a junior ADU inside an existing home. The challenge is that HOA architectural review boards in San Marino control elevations, materials, and roof lines, which means a permit-ready set of plans is only half the work. Top Tech Builders handles design and construction under one roof, so your ADU drawings arrive already calibrated to the materials and roof profiles the review board expects. We have been delivering design-build remodeling and new construction across Southern California since 2019, and our in-house team manages every phase without handoffs to outside subs. If you are planning an ADU in San Marino, contact us to start the process.
ADU Construction in San Marino
San Marino is a suburban city in Los Angeles County where single-family custom and tract homes sit on larger-than-average lots, making detached ADUs a practical fit for many properties. Because the city falls within an HOA-governed environment with strict architectural review, every ADU project must match the primary residence in materials, roof line, and exterior finish before the city will process a permit. Top Tech Builders accounts for those review requirements at the design stage, not after a rejection. Our team prepares construction drawings, coordinates architectural review submissions, pulls city permits, and builds the structure with the same crew that drafted the plans. This end-to-end approach, in place since our founding in 2019, removes the coordination gaps that slow most ADU projects. Whether your goal is rental income, multigenerational housing, or a home office, we can build a code-compliant ADU that fits your lot and your budget.
HOA review can add weeks and can veto material choices the city would have approved.
What that involves
- Detached ADU design and construction sized to your lot and San Marino HOA guidelines
- Garage conversions that preserve exterior character while creating livable square footage
- Junior ADUs built within your existing home footprint with minimal disruption
- Attached ADU additions that match the primary structure in materials and roof profile
- Full design-build service from initial drawings through final inspection with one in-house team
