San Mateo Sewer Laterals & Local Code Requirements

San Mateo property owners are responsible for maintaining, repairing, and replacing the private sewer lateral that connects their building to the public sewer main. This lateral may run beneath a sidewalk or street, which means repairs can involve the public right of way. The City of San Mateo identifies several events that can trigger a private sewer lateral inspection, including property sale, qualifying remodeling or addition work, certain commercial or multifamily sewer overflows, and changes to a property’s sewer customer class.

Work in the public right of way may require an encroachment permit from the city. The California Plumbing Code is part of San Mateo’s adopted building-code framework, so sewer and plumbing work needs to meet those standards. Requirements can change, so property owners should confirm current obligations with the City of San Mateo or a qualified plumbing professional before starting regulated sewer work.

Plumbing Repairs, Replacements & Installations

Our plumbing services include:

• Drain cleaning. Slow or clogged drains can quickly disrupt your daily routine. We remove buildup that can restrict flow and contribute to recurring blockages.
• Gas line plumbing. Gas lines require careful handling and precise installation. We provide gas line repairs, replacements, and new appliance connections.
• Leak detection and repair. Hidden leaks can lead to significant damage if left unaddressed. We use leak detection methods to locate hidden water loss and make targeted repairs.
• Fixtures. Whether you’re upgrading outdated fixtures or addressing performance issues, we install and repair faucets, sinks, showers, and more.
• Maintenance. We inspect plumbing systems for developing problems and recommend maintenance based on what we find.
• Sewer line replacement. Damaged or failing sewer lines can cause serious disruptions. We replace sewer lines when spot repairs aren’t appropriate.
• Trenchless sewer line work. When appropriate, we offer trenchless solutions that can reduce disruption to your property. This approach can repair or replace sewer lines without extensive excavation.
• Water line services. We handle water line repairs and replacements.
• Whole-home repiping. Whole-home repiping replaces substantial portions of a property’s piping system. It may be appropriate for older systems with recurring leaks or reduced performance.
• Water heaters. We repair and replace both traditional and tankless water heaters. We also install new systems and explain the available options based on your property’s needs.
