Plan Check Says “Add Sprinklers”? There’s a Smarter Way to Comply.

The "Plan Check" Reality

Receiving a correction letter requiring fire sprinklers is a common bottleneck in California ADU projects. Whether it’s due to the primary home being sprinklered, the ADU’s size, or its distance from the street, a "sprinkler mandate" often brings:

  • Utility Fees: $2,000–$12,000 for water meter upgrades.
  • Infrastructure Stress: Requirement for a 1" water main or a 300+ gallon storage tank.
  • Project Delays: 4–8 weeks of additional administrative "red tape."
