Why National City chooses 5 IN 1 Construction
National City is one of the oldest cities in San Diego County (incorporated 1887) with a housing stock that goes back to the early 1900s. Many craftsman bungalows, mid-century post-and-beam homes, and 1950s ranchers. Remodels here often involve older plumbing (galvanized supply lines, cast-iron drains) that should be addressed when walls are open. Permits go through the City of National City Engineering and Building Department.
We have been remodeling National City homes since 1987. The Carrasco family runs every job site, the same in-house crew handles your project from rough-in to final walk, and we pull every permit in your name. No subcontractors, no surprise fees, and a one-year workmanship warranty.
