Daly City isn't one housing market — it's a dozen. The postwar Doelger tracts in Westlake and the surrounding hills were built fast on slab foundations with galvanized supply lines that are now reaching the end of their service life. Serramonte and Crown Colony are dense with condos and townhomes where one leak can travel through shared walls and ceilings. The blocks along Mission Street and in Original Daly City have the city's oldest homes and sewer laterals, while Bayshore's flatter lots collect storm water the hillside neighborhoods shed. Add the marine layer that keeps indoor humidity high for months at a time, and the same leak dries slower here than it would a few miles inland.
This page is the starting point for every Daly City neighborhood we serve. The table below summarizes the water problems each area's housing is most prone to, and each neighborhood page goes deeper: local housing stock, common causes, and answers to the questions homeowners there ask most. If you're dealing with water right now, our 24/7 emergency water damage service covers the whole city, and the water damage restoration page explains the full process from extraction to rebuild.

Utility problem or damage inside the house?
Most Daly City addresses get water from the City of Daly City Department of Water and Wastewater Resources; some areas, including parts of Broadmoor and Colma, are served by Cal Water's Bayshore District. Call your provider (or the City of Daly City) for a water main break, a problem at the meter, or a flooded street. For anything inside the home — a burst pipe, a flooded garage, a sewer backup — shut off the water at your main valve if you can and call us at (201) 277-9344.

Neighborhood questions, answered
Most of Daly City is served by the City of Daly City Department of Water and Wastewater Resources. The city buys roughly half of its water from the San Francisco regional system (Hetch Hetchy and local Crystal Springs watersheds) and pumps the rest from its own groundwater wells. California Water Service's Bayshore District also serves some addresses in Daly City, Broadmoor, and Colma, so check the name on your water bill. Call your water provider for a break at the street or meter; call a plumber and a restoration company for leaks and damage inside the house.
It depends on the type of problem. Flat, low-lying blocks such as parts of Bayshore collect storm water, homes at the bottom of hillside runoff paths take water into ground-level garages during heavy rain, and the older housing in Westlake, Original Daly City, and the Doelger tracts tends to have aging galvanized supply pipes and sewer laterals. Our neighborhood pages describe the specific risks for each area.
Yes. We cover all of Daly City — the neighborhoods listed on this page, which also include Sterling Park just across the line in Colma — plus unincorporated Broadmoor, the rest of Colma, and the surrounding Peninsula cities and southern San Francisco neighborhoods. A real person answers (201) 277-9344 around the clock and can tell you how soon a crew can reach your address.
For a flooded street, a blocked storm drain, or a water main break, contact the City of Daly City (or your water provider) so they can address the public side. For water already inside your home or garage, protect people first, shut off power to wet areas if it's safe, and call a restoration company to extract the water and dry the structure before mold starts. Our Daly City flooding guide walks through both sides.
