Full Breakdown

Under the County's water conservation chapter, letting an outdoor water leak from broken or defective plumbing, sprinklers, or irrigation systems go unfixed for more than seven days after the County notifies the owner is a prohibited activity in unincorporated Santa Clara County. The Director of Planning and Development, Zoning Investigators, the Building Official, or the Code Enforcement Manager can cite the property. A first violation draws only a written warning; a second within 12 months costs $100, a third $200, and each further violation within that period $500, on top of any other legal remedy the County pursues.

Violations & Fines

First violation: written warning by mail. Second violation within 12 months: $100 fine. Third: $200. Each further violation in that 12-month period: $500.

Frequently Asked Questions

What if I fix the leak before the County notices?
The rule only applies after the County notifies you in writing - voluntary repairs made before that notice trigger no violation.
