San Mateo General Contractor

Atlas General Construction (CSLB #1059664) serves San Mateo homeowners and businesses with full-service ADU construction, new home builds, whole-home remodels, and commercial tenant improvements. San Mateo’s diverse housing stock — from Craftsman bungalows in Baywood to modern condos near the Caltrain corridor — requires a contractor who understands the city’s specific planning and building requirements.

San Mateo is an outstanding market for ADU development. The City of San Mateo has streamlined its ADU permitting process under state law, and we take full advantage of pre-approved ADU programs to accelerate your timeline.

We build detached ADUs, attached ADUs, garage conversions, and JADUs throughout San Mateo, including in neighborhoods like Baywood-Aragon, Beresford, Shoreview, and Downtown San Mateo.

Full-service delivery: design, engineering, permits, construction, and certificate of occupancy.

Whether you’re building on a vacant infill lot or replacing an existing structure, Atlas manages the full new construction process in San Mateo:

• Architectural plan coordination and permit-ready submittals
• San Mateo Building Division plan check management
• Structural engineering, grading, and foundation work
• Complete build-out through final inspection
• Energy compliance (Title 24) and all-electric readiness
