Areas Served

The primary service area centers on San Pedro, CA and nearby Los Angeles neighborhoods along the coast and harbor. Projects often come from older Craftsman and bungalow homes in coastal zones where salt air and shifting soils affect plumbing and foundations.

Company History

12ONE12 Builder's Group began as a small trades crew focused on home repairs in the harbor area. Over several years the firm added licensed plumbers and general contractors to expand into remodels and new construction. Growth came steadily through local referrals and repeat clients in SAN PEDRO and surrounding Los Angeles communities.

The company developed practical standards for coastal homes: corrosion-resistant materials, moisture-aware installation, and straightforward permitting assistance with LA city departments.

Leadership

The founder has two decades of hands-on construction and plumbing experience and grew up in the South Bay. Leadership keeps a local presence by attending city planning meetings and working with neighborhood groups on ADU policies and storm-prep resources. Staff training focuses on code compliance and safe gas-line practices.

• ADU and guest-house construction tailored to Los Angeles zoning and small-lot building.
• Practical plumbing fixes for salt-air environments — material choices that last.
