Coast Design & Build in College Area holds CSLB license #881254 and operates a San Diego design-build general contracting firm from Suite D at 6602 El Cajon Boulevard in the 92115 ZIP, covering kitchen remodeling, bathroom remodeling, solar panel installation, roofing, HVAC, concrete, and ADU construction under a single contract. The El Cajon Boulevard office sits in the commercial corridor between SDSU and the City Heights border, and the company has maintained the location since its founding in 2010, drawing remodel clients from the surrounding College Area and Rolando residential neighborhoods. Kitchen remodels run the full scope from cabinet demolition through countertop templating, backsplash tile, plumbing fixture connection, and appliance installation, with the design-build model consolidating architect, engineer, and trade coordination under one project manager. Flooring replacement is a common add-on scope during kitchen and bath remodels, and Star Flooring & Remodeling in Grantville handles the hardwood, LVP, and tile flooring installations that run concurrently with Coast's cabinetry and countertop work. Bathroom remodels follow the same single-contract structure: demolition, framing modifications, rough plumbing and electrical, waterproofing, tile installation, fixture setting, and final trim — all permitted and inspected under the company's general-building license. Solar panel systems are designed and installed in-house, with structural engineering for roof-mount arrays and electrical interconnection to SDG&E's NEM billing system handled within the same crew rather than subcontracted to a third-party solar installer. The design phase produces 3D renderings that allow homeowners to visualize cabinet layouts, countertop materials, and fixture placements before construction begins, reducing mid-project change orders that inflate cost and delay completion. Concrete work — driveways, patios, retaining walls, and foundation repair — extends the company's scope beyond interior remodeling into exterior hardscape, serving the same homeowners who often bundle a patio pour with a kitchen or bath project to consolidate permit fees and construction disruption. Pre-construction termite and pest inspections on remodel projects are standard protocol before opening walls, and Harbor Pest Control in Grantville provides the Section 1 and Section 2 reports that lenders and the building department require before framing can proceed. The Carlsbad satellite office at 1902 Wright Place expands the company's geographic reach into North County, but the El Cajon Boulevard location remains the primary base for the central and eastern neighborhoods of San Diego.
