For residential remodeling and additions in Lakeside, Bechthold Construction has operated from Casa Grande Avenue since 1989 as a sole proprietorship under Gregory Steven Bechthold. Permitted project history includes a 1,054-square-foot single-family addition on Westhill Road encompassing bedroom, dining room, and family room framing alongside a 1,284-square-foot roof restructure, the type of multi-trade scope that requires coordinated electrical rough-in from Arce Electric on Gardena Road. Interior partition work on that Westhill project added 16 linear feet of closet framing within the existing envelope, demonstrating the firm's capacity to integrate new load paths into pre-1980 stick-built homes common along Lakeside's hillside lots. Foundation-to-finish sequencing on additions of that scale also demands accurate drain-waste-vent tie-ins, a phase typically coordinated with Tatum Plumbing Co on Woodside Avenue. Highest-complexity engagements involve second-story pop-top additions requiring temporary shoring, engineered ridge beams, and Simpson Strong-Tie moment-frame connections to meet current California Residential Code seismic provisions.
