Commercial Plumbing Across the Bay Area
Restaurants, retail, offices, HOAs, and multi-tenant buildings have plumbing needs that a residential plumber is not set up for — volume, uptime, code, and documentation. The Otter Squad is a union C-36 contractor built for commercial plumbing work, and we camera-verify and document the condition of your lines so you have a defensible record for tenants, ownership, and capital planning. Licensed CSLB #1053855, C-36 and C-42, union labor, available 24/7 at (925) 397-2271. Clear Lines or You Don't Pay a Dime.

When to Call Us for Commercial Plumbing
A commercial plumbing problem costs you tenants, inspections, or revenue. These are the signs to call before that happens.
- Multiple fixtures or floor drains backing up across a tenant space or building.
- A tenant improvement, lease turnover, or build-out that needs plumbing rough-in to code.
- A health inspector or property-management citation tied to a plumbing or drain issue.
- A water heater or gas line that cannot keep up with commercial demand.
- A recurring drain or grease issue that returns after every cleaning.
- A property that needs a documented plumbing condition report for ownership or a sale.
How a Commercial Plumbing Call Runs
Every commercial job runs in the same order, and you get documentation that fits your capital plan — not just a fix and an invoice.

What Affects the Cost of Commercial Plumbing
Commercial plumbing is bid per job, not off a rate card. What we promise is a free assessment and a firm written bid before any work begins. These are the factors that move the number.
- •Scope of the work — a single fixture repair, a line replacement, or a full build-out rough-in.
- •Whether the work touches a public street or sidewalk, which adds an encroachment permit.
- •After-hours or weekend labor to keep a business open during the repair.
- •Permit and inspection fees for the governing city or district.
- •Documentation requirements — condition reports, capital-planning records, or lender documentation.
- •Access — whether the work is in a finished tenant space, a kitchen, or a mechanical room.
One Vendor for Plumbing, Sewer, and Gas
A property that uses one contractor for plumbing, another for sewer, and a third for gas ends up with gaps. We hold the licenses to cover all three.
As a C-36 and C-42 contractor, we handle commercial plumbing, commercial sewer, and commercial gas under one license, with hydro jetting, water heaters, and grease trap service in the same shop. That means one accountable vendor, one set of documentation, and one number to call when something goes wrong.
Alfredo Ortiz
Owner, The Otter Squad · C-36 & C-42 #1053855
I am Alfredo Ortiz, and I have spent more than 30 years in the plumbing trade. The Otter Squad is my family's company, Latino-owned, licensed under CSLB #1053855 for C-36 plumbing and C-42 sanitation, and staffed by union, UA-trained crews. On a commercial job the stakes are different than a house — a backed-up line can close a kitchen or a floor of tenants. My rule is the same but it matters more: diagnose first, document it, and give you one written bid before anyone digs. Call me any time, day or night, at (925) 397-2271.
