California Contractors License #905491 backs Silva Custom Builders' design-build remodeling and construction practice from a 1859 Bacon Street base in OB, running parallel project verticals across medical, restaurant, laboratory and residential markets. Medical office buildouts cover architectural design and construction of dental suites, imaging rooms, surgical facilities and primary-care interiors — work that overlaps with the office-fitout and workplace-strategy services delivered by firms like CRUX Workplace Consultants when a tenant improvement also requires programming and space-utilization analysis. Restaurant construction is a separate vertical for the firm, covering kitchen build-outs, hood and grease-trap installation, ADA-compliant front-of-house design and the permit coordination that sit-down restaurant occupancy requires. Laboratory renovation — pharmaceutical, research and clinical — adds a noise-vibration-dust mitigation protocol that lets adjacent operating facilities keep running through construction, with electrical service upgrades and dedicated circuit pulls coordinated alongside specialists like Sattler Solar Inc. on jobs that combine lab buildouts with rooftop solar additions. Residential design-build remodels and room additions round out the practice, with all phases handled in-house from initial permitting through final inspection. The most complex deliverable is laboratory renovation inside an active facility, where construction must proceed without interrupting research operations on the floor next door.
