Holding CSLB License #353563 with B-General Building, C-10 Electrical, and C-20 HVAC classifications, Donald E Anderson Construction has operated from 3137 El Cajon Blvd since 1978. The multi-trade license scope eliminates subcontractor handoffs on projects where San Diego Roofing completes the envelope and Donald E Anderson Construction runs the wiring and ductwork below it. Fifty-one City of San Diego building permits document the company's work across new residential construction, kitchen and bathroom remodels, and multi-room renovations throughout the 92104 ZIP code. Final finishes on completed framing and mechanical rough-ins are regularly paired with exterior coating work from Otis Merry Painting. The company's highest-complexity engagements are whole-house rewires combined with furnace-to-heat-pump HVAC conversions in North Park's pre-war bungalow stock, where all three trade classifications deploy under a single contractor.
