Carrillo Tile & Remodeling in College Area holds CSLB license #907986 under the B-General Building classification in San Diego, qualifying owner Rodney Carrillo's crew for full bathroom and kitchen remodels from the company's base on University Avenue in the 92115 ZIP. The scope covers demolition through finish: substrate preparation, waterproofing membrane application, mortar-bed and thin-set tile installation, grouting, and final caulk and trim on showers, tub surrounds, backsplashes, and floor systems. Rodney Carrillo runs the jobs personally, handling layout, cut planning, and the precision work on inside corners and shelf niches that separates a trade-level installation from a handyman tile job. A tile remodel typically follows or overlaps with interior painting, and Local San Diego Painting coordinates wall prep and finish coats around Carrillo's tile schedule on projects where both trades share the same bathroom or kitchen. ADU construction falls within the B-General Building license, and Carrillo's crew has completed garage-to-ADU conversions in the College Area and Rolando neighborhoods where the city's streamlined ADU permitting process has accelerated accessory-unit construction on residential lots near SDSU. University Avenue's commercial frontage between College Avenue and 70th Street anchors a service-trade cluster, and the shop draws remodel referrals from property managers overseeing rental units in the dense student-housing corridor south of Montezuma Road. Material selection covers porcelain, ceramic, natural stone, and large-format tiles up to 24-by-48 inches, with Schluter DITRA uncoupling membrane and Kerdi waterproofing board specified on wet-area installations to meet current San Diego building code for shower and tub enclosures. Plumbing rough-in adjustments — relocating shower valves, moving drain positions for curbless showers, and extending supply lines for freestanding tub fillers — run concurrently with the tile prep, and Ideal Plumbing Heating Air Electrical in Allied Gardens handles the valve and drain relocation work that precedes the waterproofing layer. The B-license scope also covers framing modifications for niche recesses, bench seats, and half-wall pony walls that require structural header support before the tile substrate goes up.
