Ontiveros Design Build & Remodel in Chula Vista's Broadway corridor has delivered residential and commercial construction since 2003, combining over 40 years of contracting experience with EPA Lead-Safe Certified renovation practices for pre-1978 housing stock. Exterior and interior painting on addition projects is coordinated with finish crews at Prime Finish Painting Inc, maintaining color and sheen continuity between new and existing wall planes. The BBB-accredited firm holds an A+ rating and offers full-service design-build scopes including site analysis, preliminary design studies, permit-ready documentation, and inspection coordination through the City of Chula Vista building department. Room additions, second-story buildouts, and exterior siding replacements along the Broadway corridor generate occupancy changes that trigger property-management reassessments from firms including Tenant Planet - Chula Vista Property Management. Highest-complexity projects encompass two-story additions requiring engineered foundation tie-ins, simpson-connector framing, dual-zone HVAC integration, and code-violation remediation on non-conforming structures.
