Independently owned by the Schwartz family and listed on the Gaslamp Quarter Association, Downtown Ace Hardware at 675 Sixth Avenue is the only dedicated hardware retailer in downtown San Diego's core. The store stocks Benjamin Moore paints with custom color-matching capability and carries full power tool lines from Milwaukee, DeWalt, and Craftsman, supplying the same residential and commercial painting projects served by contractors like CertaPro Painters of La Jolla and Central San Diego. A tool rental program allows condo and apartment residents to access power saws, drills, and sanders without long-term storage commitments — a service designed specifically for downtown's high-density residential towers. The inventory extends into urban gardening supplies, grilling equipment sized for balcony and patio use, and household hardware across fasteners, plumbing fittings, and electrical components. Plumbing supply purchases at the store feed the same residential maintenance pipeline served by licensed contractors like Colepepper Plumbing in Middletown for fixture installation and pipe repair. Same-day delivery, curbside pickup, and in-store assembly service are available alongside bilingual English-Spanish assistance for the surrounding East Village and Gaslamp Quarter residential base.
