SGM Builders Inc. provides a complete range of construction services for homeowners and business owners in Hollister, Gilroy, Morgan Hill, Los Gatos, Saratoga, and Los Altos. Every project is managed by our team from the initial consultation through final inspection, so you always know who’s responsible for the work.
Below is an overview of everything we do. Each service page has more detail about the process, typical costs, and what to expect.

Building an accessory dwelling unit is one of the smartest investments a California homeowner can make right now. SGM Builders designs and builds detached ADUs, attached ADUs, garage conversions, and junior ADUs (JADUs) across Hollister, Gilroy, Morgan Hill, and the South Bay. We handle everything from permit applications to final city inspection.

The kitchen is the heart of your home and the room where the right contractor makes the biggest difference. SGM Builders handles complete kitchen renovations, from layout changes and wall removals to custom cabinetry, countertops, flooring, lighting, and appliance installation. Whether you need a cosmetic refresh or a full gut remodel, we manage every detail.

A bathroom remodel can range from a simple fixture and tile update to a complete renovation with custom tile, walk-in showers, freestanding tubs, and heated floors. We handle the full spectrum including the waterproofing, plumbing, and electrical work that make the difference between a bathroom that lasts and one that doesn't.

Beyond kitchens and bathrooms, we handle room additions, full-home renovations, and interior remodels that transform how your family uses your space. Whether you're expanding a living room, adding a bedroom, or modernizing a home that hasn't been updated in decades, we bring the experience and planning to do it right.

Outdoor living space adds real value to your property and it's one of the most enjoyable upgrades you can make. We build patios, pergolas, covered patios, concrete driveways, decks, and custom outdoor living areas designed for how you actually use your backyard.

Your roof protects everything underneath it, and it deserves a contractor who understands the materials, the local building codes, and the South Bay climate. SGM Builders handles re-roofs, shingle replacement, tile installation, and roof repairs throughout Hollister, Gilroy, and Morgan Hill.

Not sure where to start? Our design-build approach means the same team that draws your plans is the same team that builds your project. We offer ADU floor plan design, home renovation layouts, room addition plans, and permit-ready construction drawings all coordinated with the specific requirements of your city's building department.

SGM Builders also serves business owners with tenant improvements, commercial remodeling, restaurant and retail buildouts, office construction, and new commercial projects. We understand that business timelines are tight and every week of delay costs revenue so we plan carefully and execute efficiently.
We offer ADU construction, kitchen remodeling, bathroom remodeling, home renovation (including room additions), roofing, hardscaping, design and planning services, and commercial construction. We handle both residential and commercial projects across the South Bay and San Benito County.
Yes. Our design-build approach means we coordinate the design, produce permit-ready plans, and build the project — all under one roof. This eliminates the disconnect that happens when an architect designs something and a separate contractor has to figure out how to build it.
Start with a free consultation. Tell us what you’re trying to accomplish, and we’ll recommend the right approach. Sometimes a project starts as a kitchen remodel and evolves into a broader renovation once we discuss possibilities. There’s no commitment just a conversation.

Tell us what you're imagining for your backyard. We'll visit your property, discuss your ideas, and put together a plan and estimate that turns your outdoor space into something you'll actually use.
