Schroeder Construction & Development in Carlsbad Village holds CSLB #494954 with dual B (General Building) and C-36 (Plumbing) classifications, a combination that consolidates rough-in plumbing and framing under a single permit holder. Incorporated in 1998 on State Street, the firm has pulled 14 building permits across San Diego County, including tenant improvements and new accessory dwelling units that require Wheyland Electric-grade panel upgrades for ADU sub-metering. The dual-classification license eliminates the need for a separate plumbing subcontractor on residential remodels, reducing coordination delays common in Carlsbad's permitting cycle. New construction and renovation scopes extend to full structural framing, and the firm coordinates envelope work with Built 2 Last Roofing for Title 24 compliant roof assemblies on coastal builds. ADU projects under the firm's scope typically involve 60-amp sub-panel installations and dedicated 3/4-inch copper supply lines run from the primary residence's main shutoff.
