Colinas Contractors, Inc. in Carlsbad's Aviara corridor holds CSLB license #947351 (Class B and C-9 Drywall) and operates from Yarrow Drive as a multi-state general contractor licensed in California, Nevada, Colorado, and Arizona. The firm focuses on commercial tenant improvements in multi-story buildings, combining drywall framing, metal-stud partition systems, and Level 5 finish work — interior buildouts that transition directly to the coating and wall-covering stages handled by Coastal Colors Painting Company on shared project timelines. Twenty-seven building permits across San Diego County include concentrations in Kearny Mesa and North County commercial parks, with healthcare and office sectors accounting for the bulk of completed square footage. Beyond partition and ceiling work, tenant-improvement scopes extend to flooring transitions between carpet, LVT, and porcelain tile, with precision cuts and waterproof membrane installations subcontracted to Know Howe Tile for wet-area and high-traffic zones. Full-building TI packages include fire-rated shaft wall assemblies, acoustic STC-rated partition systems exceeding 55 dB, and seismic drywall bracing per California Building Code Section 2508 for multi-story occupied structures.
