Per 2013 California Building Code (CBC) Section 903.2.8 and 2013 California Residential Code (CRC) Section R313.2, an automatic residential fire sprinkler system shall be installed in one and two family dwellings. Stand alone and multi-purpose wet-pipe sprinkler systems that do not include the use of anti-freeze shall be designed in accordance with CRC R313.3. Per the 2013 Edition of NFPA 13D, any proposed use of anti-freeze requires the product to be listed. Since there currently are no listed products available, additional considerations and documentation are required if proposing to use anti-freeze within the sprinkler system.
The installation of a fire protection system, excluding an electrical alarm system, shall be performed only by a contractor holding a fire protection contractor classification (C-16), a contractor holding a plumbing classification (C-36) or by an owner-builder of an owner-occupied single -family dwelling, if not more than two single-family dwellings on the same parcel are constructed within one year.
The design of the fire protection system can be by a fire protection engineer, a civil engineer, a C-16 contractor or a NICET II/III. The person or company that designs the system does not have to install it but they do need to stamp the plans. If a C-36 is performing the install, either the designer or a C-16 must perform the hydro-test and inspection. Only the C-16 may do the annual/5-year inspections.
Within the Town of Truckee and per agreement with the Truckee Fire Protection District, the review of plans, permitting and inspecting of these systems in one and two family dwellings is the responsibility of the Building Division.
A residential fire sprinkler permit shall be submitted, reviewed, approved and issued prior to requesting a rough inspection on the residential permit. Please allow for appropriate amount of time for this process. (The water utility district requires preliminary information regarding the sprinkler system demands in order to determine their water hook up fees. Since a copy of the receipt for paid water fees is required prior to issuance of the permit for the residence, it is recommended the sprinkler design occurs concurrently with residence).
Submittal for residential fire sprinkler system requires:
- Supporting documentation if using anti-freeze.
- A separate permit application request form.
- (3) sets of plans (designed by C-16 Contractor).
- (2) sets of hydraulic calculations.
- (2) copies of the latest technical data/manufacturer's data for proposed sprinkler heads and all proposed fixed loss devices.
- A plancheck fee of one hour at the current standard hourly rate (if the square footage of habitable space and garage is less than 2500 square feet); or two hours at the current standard hourly rate (if the square footage of habitable space and garage is greater than 2500 square feet) is charged at the time of permit submittal.
Prior to issuance of the residential fire sprinkler permit, written approval by Truckee Donner PUD (530) 587-2896 shall be obtained by the applicant (suggest concurrent submittal to the TDPUD at the time of permit submittal). The TDPUD will verify the final sprinkler design required water flow demand is available or require appropriate upgrades. For this reason it is recommended that TDPUD is included in the development phase of the project as noted above.
Once plans are approved and TDPUD approval is obtained the permit can be issued.
- A permit fee of approximately one hour at the current standard hourly rate (0- 2500 square feet); or approximately two hours at the current standard hourly rate (>2500 sq. ft.) will be due at issuance. (Additional minimal fees are generated for these permits - contact permit technician regarding actual final payment amount prior to completing a check for payment).
Prior to final of the sprinkler permit, written approval by Truckee Donner PUD (530) 587-2896 shall be obtained by the applicant. The TDPUD requires a test of the backflow prevention device in order to obtain their final approval. This test and approval shall oiccur prior to requesting final approval by the building division.
