Trinity Construction is a general contracting and construction company in San Diego's College Area, operating from 4922 69th Street in the 92115 ZIP east of SDSU. The company handles all phases of residential construction, remodeling, and improvement across San Diego County, with on-site service and online estimate processing available through the project intake system. The 69th Street address places the operation in the residential grid between El Cajon Boulevard and University Avenue, a section of College Area where post-war bungalows, mid-century apartment buildings, and 1970s-era fourplexes generate continuous renovation and structural repair demand. Mechanical and electrical rough-in on remodel projects coordinates with trade specialists, and HVAC system upgrades during interior gut-renovations run alongside firms such as Fabulous Homes Heating & Air in College Area for duct installation and system commissioning. The company maintains a 402-photo portfolio documenting completed project phases from demolition through final finish. Framing, drywall, flooring, painting, and finish carpentry fill the interior build-out scope, while exterior work covers stucco repair, window replacement, and roofing coordination. Plumbing rough-in and fixture installation on bathroom and kitchen remodels pulls in subcontractors from Grantville's trade corridor, with re-piping and drain-line scope handled by firms including American Plumbing Group in Grantville. The College Area housing stock within a two-mile radius of SDSU supports both owner-occupied renovation projects and investor-driven rental-property upgrades on the multifamily buildings that line University Avenue and El Cajon Boulevard.
