Licensed Plumbing Installation for Remodels and New Construction
Plumbing installation is the work behind the walls and under the floor before drywall, tile, and cabinets go in. It covers rough-in for supply, drain, waste, and vent lines, drain and supply relocation, gas lines, fixture setting, and repiping an older home during a remodel.
Because the City of San Diego requires a permit to alter, add, or replace a plumbing system, we pull the correct permit, meet the inspector at rough-in and final, and pressure-test every line before it is covered.
Whether you are building an ADU, remodeling a kitchen, or repiping a 1950s home, our licensed plumbers meet California code and CalGreen standards. We handle the plumbing scope only and coordinate with your general contractor, so tile, cabinets, and electrical stay with the right trades.

Plumbing Installation Questions, Answered
Still have a question? Call us at (619) 637-5215 — we are happy to help.
Do I need a permit for plumbing installation in San Diego?
Yes. The City of San Diego requires a plumbing and gas permit to alter, add, or replace a plumbing system. A Simple No-Plan permit covers minor work such as water heater replacements except tankless, water and sewer pipe repairs, drain repairs, water softener installs, and PRV replacements. Larger remodels need a full permit.
When does the rough-in inspection happen?
Rough-in inspection happens after the supply, drain, waste, and vent lines are installed and pressure-tested, before drywall or tile covers them. Final inspection happens after fixtures are set. Passing both keeps your project on schedule.
How much does a plumbing-only remodel cost in San Diego?
Plumbing-only ranges run about $1,800 to $3,500 for a powder bath, $3,500 to $6,500 for a full bath, and the same for a kitchen. ADU rough-in starts near $8,500. Slab drain relocation is $1,500 to $3,500 and raised-foundation work $800 to $1,800, excluding tile, cabinets, and electrical.
What low-flow fixtures are required in a permitted remodel?
CalGreen caps toilets at 1.28 gallons per flush, showerheads at 1.8 gallons per minute, bathroom faucets at 1.2 GPM, and kitchen faucets at 1.8 GPM. Drinking-water parts must be lead-free under AB 1953. We supply compliant fixtures or install yours.
