Marroquin Construction Corporation in College Area handles residential remodels and tenant improvements from 6362 University Avenue in San Diego, roughly a mile south of SDSU. The firm operates under CSLB #927447 (B — General Building classification) and has maintained a Blue Book listing since 2010, with primary trade lines in carpentry, millwork, and architectural terra cotta detailing. Robin Marroquin founded the company, and its scope runs from concrete flatwork and drywall installation through electrical rough-ins and interior painting — a breadth of trade coverage that keeps single-contractor accountability on mid-size renovation projects where Lightning Electric typically runs the panel upgrades and circuit remediation in College Area properties. Flood restoration is a secondary line: the company mobilizes for water-damage mitigation, structural dryout, and rebuild on the same 92115 housing stock where post-war bungalows and 1960s apartment buildings generate steady remodel demand. Property assessment reports produced in-house give homeowners a documented condition baseline before permitting begins. Exterior painting projects follow the same prep-and-finish protocol that Nordby Painting applies on dedicated exterior scopes across College Area. The full permit-to-punchlist model covers framing, finish carpentry, flooring, and final inspection coordination with the City of San Diego Development Services Department.
