Residential and commercial general contracting in La Mesa since 1991 defines Mezz Construction Inc. on Oregon Avenue, a firm carrying an active CSLB general building classification and USDOT registration #3221886 for intrastate material transport. New multi-family construction is a core scope, with permitted three-story R-2 projects exceeding $1.6 million in valuation—structural framing paired with coordinated roofing phases handled by subcontractors such as Coastal Crest Roofing on La Mesa infill sites. The design-build workflow covers kitchen and bathroom gut-renovations, room additions with engineered headers, and full ground-up single-family construction from foundation to finish. Exterior finish packages include stucco application, siding replacement, and multi-coat paint systems applied in coordination with coating specialists like Procoat Painting San Diego across the Fletcher Hills area. Highest-complexity projects involve structural steel moment-frame installation on multi-story mixed-use buildings requiring Title 24 energy compliance and CBC lateral-force engineering.
