San Mateo County Utility Lien List
70 San Mateo County properties carry an open utility lien — #25 of California's 58 counties and 0.1% of the statewide total. A utility lien records when water, sewer, or municipal service bills go unpaid long enough that the provider attaches the debt to the property. The amounts are usually small, and that's the point: nobody lets a utility bill become a recorded lien on a home that's being looked after. It's one of the earliest recorded signs of a property nobody is minding. Each lien here is matched against recorded releases, so the list holds only debt that is still open.

Frequently Asked Questions
How many properties with open utility liens are there in San Mateo County?
Properant tracks 70 properties with open utility liens in San Mateo County as of October 12, 2026 — ranked #25 of California's 58 counties — counted from recorded county documents with releases and cancellations removed.
Why are utility liens in San Mateo County a useful lead source?
Because of what a recorded utility lien says about the owner, not the amount. Attentive owners never let a water bill become a lien — so when one records, it usually marks an empty house, an heir who walked away, or an owner in real trouble. Stacked with tax delinquency or a vacancy flag, it's the profile of a property whose owner has already moved on.
