Mako Construction in Coronado at 1517 Tenth Street is a second-generation custom home builder that works exclusively on the island, with more than seventy completed projects since the firm's establishment around 2000. The Coronado-only focus produces deep familiarity with the city's permitting office, coastal overlay zone requirements, and lot-by-lot neighborhood context — an institutional knowledge base that island agents at Simone Real Estate Group leverage when matching buyers with teardown or heavy-renovation properties. Most trades stay in-house, with specialty subcontracting routed to a fixed roster that includes Kephart Plumbing, Rita Mata Painting, and Dixieline/ProBuild for framing lumber and engineered-wood products. Coronado's residential building history — documented through the archives of the Coronado Historical Association and Museum at 1100 Orange Avenue — shapes design decisions on projects adjacent to designated historic structures in the 92118 Village core. Ground-up builds on Coronado lots typically run 2,800 to 5,500 square feet, integrating post-tension slab foundations, advanced framing at 24-inch centers, and whole-house mechanical ventilation systems sized to ASHRAE 62.2 airflow standards.
