That Guy Construction & Maintenance in Chula Vista holds CSLB license #1054982 under the B–General Building classification, covering kitchen remodels, bathroom renovations, and ADU room additions from its Fortuna Street base in the 91911 zip code. Kitchen gut-renovations typically involve rerouting supply and waste lines—plumbing scope that runs concurrent with the drain-line work handled by Coastal Rooter – Plumbing Chula Vista when slab-leak detection surfaces during demolition. Incorporated in 2019, the firm operates in the western corridor between Palomar Street and Main Street, where post-war single-story homes built on raised foundations present recurring subfloor access challenges during bathroom tear-outs. Full exterior renovation packages that include stucco repair and re-roofing often coordinate weather-dependent sequencing with Chavez Family Roofing to keep the building envelope sealed between phases. Highest-complexity projects include load-bearing wall removals requiring engineered steel header beams, Simpson Strong-Tie post-base connections, and city-permitted structural calculations per CBC Chapter 23.
