Sheiner Construction in downtown San Diego holds CSLB license #1083621 as a Class B general building contractor, operating from Eighth Avenue in the East Village with four fully staffed crews. Kitchen and bathroom gut-renovations run through an in-house design phase where material selection, cabinet layout, and fixture placement are finalized before demolition begins—a scope-first workflow that parallels the residential planning process at Studio H Design Group. The company also founded Sheiner Homes, a separately licensed Realtor® entity, giving clients a single point of contact from renovation planning through resale if the remodel is an investment play. ADU construction follows San Diego's current accessory-dwelling-unit code, covering detached backyard units, garage conversions, and above-garage additions that require separate utility connections and Title 24 energy compliance. Rough-in plumbing for kitchen islands and freestanding tub relocations often runs through Colepepper Plumbing in Middletown, which handles the hot-water rerouting and gas-line capping that accompany full gut jobs. The highest-value projects combine second-story additions with whole-house remodels—new roof structure, relocated load-bearing walls, expanded electrical panels, and finished interiors delivered under a single permit set.
