CSLB #969787 holder King Mahdi Builders operates from University Avenue in La Mesa as a design-build general contractor serving residential and commercial clients across San Diego County since 2001. The in-house drafting team produces 3D renderings on large-format monitors before breaking ground, a pre-construction visualization workflow that feeds structural-engineering coordination with Coston Architects on permitted projects. Completed work ranges from 100-square-foot residential room additions to 12,000-square-foot commercial restaurant build-outs, with kitchen remodels and tenant improvements comprising the core portfolio. Mechanical system upgrades on those commercial projects require subcontracted HVAC installation coordinated with Jackson & Foster Heating and Air Conditioning for code-compliant ductwork sizing. The highest-value engagements involve full ground-up commercial build-outs requiring Type V-B construction, Title 24 energy calculations, and ADA-compliant egress pathways per CBC Chapter 11B.
