Holding CSLB License #941137 with B-General Building and C-36 Plumbing classifications, Mann Contracting operates from 1804 Garnet Ave in Pacific Beach's 92109 ZIP code. The contractor handles new construction plumbing rough-in for restaurants, commercial kitchens, and multi-unit residential projects, often coordinating mechanical systems alongside HVAC providers such as Patriot Air. Residential service work includes sewer line repair, drain clearing, gas line installation for barbecues and fireplaces, and water heater replacement across San Diego. The dual B and C-36 classifications allow the firm to self-perform general building work on remodel projects where plumbing reconfiguration is the primary scope, a workflow common in bathroom and kitchen renovations managed by firms such as Envision Design. Mann Contracting specializes in full plumbing rough-in packages for ground-up commercial restaurant build-outs requiring grease interceptors, floor drains, and backflow prevention assemblies.
