Holding CSLB General Building License #1013643, Maison Design/Build in Encinitas operates as an LGBTQ+-affirming design-build firm specializing in ADU construction, garage conversions, and residential additions. Garage-to-ADU conversions require structural header installation, plumbing and electrical rough-in, and egress-window compliance, with finish-level remodeling scopes handled in the same workflow that renovation specialists such as Valiant Home Remodeling apply to adjacent Encinitas properties. The firm's eco-conscious accreditation extends to material sourcing and waste-diversion practices aligned with California's CALGreen mandatory measures for new residential construction. Project types span detached ADUs compliant with California SB 9 and AB 68 regulations, second-story additions, and full interior remodels across San Diego County. Roofing integration on addition projects requires tie-in flashing details, rafter-to-ridge connections, and R-38 insulation compliance per Title 24 Part 6, with roofing installation coordinated through local contractors such as Baynes Roofing. Highest-complexity builds include detached two-story ADUs requiring independent utility laterals, seismic-rated Simpson Strong-Tie holdown connections at each shear-wall panel, and separate 200-amp electrical service per the City of Encinitas ADU ordinance.
