San Marcos construction services
Construction services for San Marcos property owners
San Marcos homeowners, business owners, and developers planning construction work can turn to Bernal Builders for residential and commercial projects. We serve San Marcos as part of our broader San Diego County coverage, traveling to North County Inland projects from our base at 3343 Durant St in San Diego. We do not maintain an office in San Marcos.
As a family-owned company established in 2017, Bernal Builders holds California CSLB License #1047688 with both General Building and General Engineering classifications. That license profile lets our crews take on structural construction, concrete, foundations, framing, excavation, and finishing work — not just cosmetic updates — and coordinate multiple trades within a single San Marcos project.
New construction and ground-up builds
For San Marcos property owners and developers planning ground-up work, Bernal Builders takes on new construction projects. Our General Building and General Engineering classifications allow us to coordinate site work, structural construction, concrete, foundations, framing, and finishing trades within a single project, along with construction consulting, design and engineering, and specialized inspections that larger builds can require.
Framing, concrete, and structural construction
Many San Marcos projects depend on structural capabilities that go beyond finish carpentry. Bernal Builders performs rough carpentry and framing, concrete work, block walls and masonry, and foundations and structural work. These services support new construction, additions, ADUs, retaining and site walls, and remodels where structural changes are involved.
ADUs and garage conversions
San Marcos property owners add accessory dwelling units for family, rental income, or flexible living space. Bernal Builders builds detached ADUs, attached ADUs, garage conversions, and addition-based ADU projects, coordinating the foundations, framing, concrete, utilities, design, and engineering your project requires. ADU regulations — including setback, height, and size rules — vary by jurisdiction and change over time; we recommend confirming current requirements with the City of San Marcos or your local building department.
Full-home remodeling
Homeowners planning a substantial renovation can rely on Bernal Builders for whole-home remodels that can span layout changes, structural modifications, framing, drywall, finishes, and paint — with roofing, concrete, or foundation work where applicable and design and engineering where the scope calls for it. Not every remodel needs every trade; we scope the work your project actually requires.
Excavation and site work
Site preparation is part of many San Marcos builds. Bernal Builders performs excavation, grading, and trenching alongside our concrete and foundation work. Where utility-related excavation is required, our SDG&E backfill and excavation capabilities and our status as a Veriforce Certified, SDG&E Signatory Contractor are relevant.
Design, engineering, consulting, and inspections
Bernal Builders provides design and engineering services, construction consulting, and specialized construction inspections — including structural and general construction inspections, property appraisal inspections, SB 721 balcony and deck inspection and repair, and engineering reports and compliance inspections. We do not provide legal advice or guarantee code compliance; we can help you understand what your project may involve and coordinate the construction work that follows.
