Semmes & Co. Builders, Inc. is a custom homebuilder and remodeler who has been serving the Central Coast of California since 1978. Our projects reflect the heart and soul of the owner while being sensitive to the local community and environment. We are a leading innovator of alternative energy and sustainable building practices.

We provide complete preconstruction and construction services customized to fit any project. Our experience makes Semmes & Co. a sought after consultant for Site Selection and Development Costing as well as for Environmental Building Systems Consulting.

We work with homeowners and architects or designers to build a team that best fits a specific project, from design through construction. This Architect-Builder Collaborative approach provides cost control and time savings, and insures that everyone’s expectations and needs are met while achieving the overall design intent.  For smaller remodels and finish improvements, we provide complete preconstruction services. Our Design/Build team can provide design and drafting in addition to feasibility assessment, working drawings or construction documents, and permit processing.

Additionally, Semmes & Co.’s expert concrete, framing and finish carpentry crews do a majority of all work as well as provide day-to-day management and quality control.

Together with other community partners such as SLO Green Build and the California Straw Builders’ Association, Semmes & Co. also works to raise awareness of green building practices for our clients, architects, subcontractors, employees, and the general public.  Through continuing education, we are able to provide the latest and most cost effective green building solutions and fulfill our commitment to training the next generation of tradespeople.
