Remodels & Fire Service

If you are remodeling or rebuilding a home or making commercial tenant improvements which triggers the addition of fire sprinklers this page will outline the process of constructing a new fire water service or hydrant.

New Unit

If you are building a brand new unit (i.e., the number of habitable units on the property is increasing) or your commercial unit is changing use, please visit the New Residential Building Water Service page for accessory dwelling unit (ADU), single-family home, commercial or another new service information.

Size of Fire Service

The size of the fire service is determined by the Fire District. They will need to review your building plans and sign off on the bottom portion of our Fire Protections Requirement Form (PDF)

Most single family residences will require our 2-inch Fire Service, either following Standard Detail S-17 or S-20, depending on the project. 


You will need to hire your own contractor to install the new Fire Service and tap the watermain in the street. This process is detailed in the Applicant Installed Service Flow Chart (PDF).

Costs & Rates

  • Each fire service will require one new 'detector check' water meter – the standard 5/8 inch size. Please refer to our current Rates and Fees page. Fire services are not subject to water capacity fees, only the cost of the meter.
  • You will also be responsible for paying an Admin/Inspection deposit to the District to cover our time reviewing and inspecting your Contractors work. This amount is determined based on the size of the project.

Request More Information

Please check the District Boundary Map to make sure your project is within our District boundaries. If it is, you may reach out for more information and a staff member will review your project and get back to you for the next steps.
