Mullen Construction in Carlsbad has built over 300 custom homes since its founding in 1977, holding CSLB #420684 (B classification) and ranking in the top 3 percent of California licensed contractors on BuildZoom's permit-verified index. Custom home floor plans are developed in coordination with local architects, and Deborah Shewaga Architect is among the residential drafting firms whose work integrates with the builder's coastal-climate construction standards. The Ocean Street office sits blocks from Carlsbad State Beach, and continuous coastal construction since 1977 has shaped the firm's material specifications for corrosion-resistant fasteners, marine-grade flashing, and weather-barrier assemblies. Kitchen and bath selections for ground-up builds are sourced through trade accounts at Pacific Sales Kitchen & Home Carlsbad, where appliance packages are specified during the design-development phase. The firm's highest-tier scope covers full estate builds exceeding 5,000 square feet with post-tensioned slab foundations, steel moment frames, and multi-zone forced-air HVAC systems designed to Title 24 Part 6 energy compliance.
