Ordinance amending Title 15 of the Municipal Code to adopting the updated California Building Standards Code7.2Page 1 of 25 AGENDA ITEM________ Town Council Staff Report Page 2 example, the Town has historically adopted the 2018 International Property Maintenance Code; the 2018 International Swimming Pool, Spa and Hot Tub Code ; the 1997 Uniform Code for the Abatement of Dangerous Buildings and the 1997 Uniform Housing Code . Local jurisdictions are required to enforce the 2019 California Building Standards Code, effective January 1, 2020. The Town may adopt an altered code or different version of the State amended code. However, any changes to the State amended code must be filed with and approved by the California Building Standards Commission. The Commission will approve local amendments if the changes are stricter than the State amended code and the local jurisdiction can justify the changes as necessary based on local climatic, geographic or topographical conditions. The State amended code traditionally is on a three-year cycle for changes to update the codes. The new code reflects changes in technology and lessons learned during the previous code cycle. Some of the more significant changes in 2019 edition include:  The California Energy Codes mandatory requ irement that all new houses have photovoltaic generation capabilities unless they meet roof shading exemptions, that quality insulation installation inspections are required on new construction or additions over 700 sq/ft and that water heater locations are pre-wired for electric water heaters.  The California Building Codes are requiring that all new garage door openers and vehicle gates will have battery backup  Attached for your reference is a 2019 CA Building Standards Code Substantial Changes Quick Reference Guide. The new codes will make buildings safer, more efficient and will help to preserve California’s resources. Except as noted below, the enclosed ordinance will adopt the State amended code with some amendments based on local conditions . The ordinance will also adopt the additional model codes noted above to assist in implementing the State amended code. This ordinance does not directly adopt the 2019 California Fire Code. As fire protection services are provided by the Truckee Fire Protection District, adopting the Fire Code is done in conjunction with the District. The District will initially adopt the 2019 California Fire Code with its local amendments on November 19th. Once the District has approved an ordinance adopting and amending the 2019 California Fire Code, the Town will ratify, amend or reject the District ordinance . The District ordinance will not be effective until it is ratified by the Town and filed with the California Department of Housing and Community Development. Correspondence from the District and a copy of the proposed Fire Code ordinance are included for the Council’s reference. We have changed wording to section 15.03.040 Fire Hazard Severity Zone Classification of our ordinance to tighten the requirements of California Building Code section 701A.3 Exception 4 and California Residential Code section R337 .1.3 Exception 4 to include remodels and additions of buildings built before July 1, 2008.This was based on meetings with Truckee Fire Protection District and Placer County Building Dept.to help with making buildings in The Town of Truckee more resistant to wildfire. We have added section 15.03.190 Protection of Exterior Wood Members Against Decay to our ordinance based on records of failed structural members of decks and the recommendations of TTEA on how to prevent decay. Page 2 of 25 AGENDA ITEM________ Town Council Staff Report Page 3 We added section 15.03.200 Storage Areas to our ordinance because we have enforced these requirements for many years and they are no longer in the Residential Code and want to maintain these requirements to be in line with other jurisdictions. In conclusion, this year’s reprinting of the California Building Standards Code and the additions/modifications to our municipal codes will certainly provide a safer environment in the Town of Truckee. FISCAL IMPACT: There is a fiscal impact to the Town that will be ongoing that is difficult to quantify. However, the Town’s fee schedule is designed to recover the costs associated with the implementation of this code PUBLIC COMMUNICATIONS: The new codes, their adoption and revision of Title 15 were discussed by the Building & Safety Division at the Building Working Group (CATT, TTEA) meetings in August and September of 2019. Notice has been provided by the publication and posting of the agenda for this meeting. ATTACHMENTS: 1. Ordinance 2019-09 Updating the California Building Standards Code Page 3 of 25 TOWN OF TRUCKEE California ORDINANCE 2019-09 AN ORDINANCE AMENDING TITLE 15 OF THE TRUCKEE MUNICIPAL CODE, TO ADOPT BY REFERENCE THE 2019 EDITION OF THE CALIFORNIA BUILDING STANDARDS CODE, WITH CERTAIN ADDITIONS, INSERTIONS, DELETIONS AND CHANGES THERETO WHEREAS, Health & Safety Code Section 17958 mandates that the Town of Truckee shall adopt ordinances or regulations imposing the same requirements as are contained in the regulations adopted by the State pursuant to Health and Safety Code Section 17922 and Government Code Section 50022.2; and WHEREAS, the State of California is mandated by the Health and Safety Code Section 17922 to impose the same requirements as are contained in the most recent edition of the Uniform Housing Code of the International Conference of Building Officials, the Uniform Building Code of the International Conference of Building Officials, the Uniform Plumbing Code of the International Association of Plumbing and Mechanical Officials, the Uniform Mechanical Code of the International Association of Plumbing and Mechanical Officials, and the National Electrical Code of the National Fire Protection Association (hereinafter referred to collectively as "Codes"); and WHEREAS, the Health and Safety Code Sections 18941.5 and 17958.5 permits the Town to make such changes or modifications to the Codes as are reasonably necessary because of local conditions; and WHEREAS, the Health Code Sections 18941.5, 17958.5 and 17958.7 make express findings that such changes or modifications are needed due to climatic, geographic or topographic conditions; and WHEREAS, the Town Building Official has recommended that changes and modifications be made to the Codes and has advised that certain of said changes and modifications to the Codes are reasonably necessary due to local conditions in the Town of Truckee and has further advised that the remainder of said changes and modifications are of an administrative or procedural nature, or concern themselves with subjects not covered by the Codes or are reasonably necessary to safeguard life and property within the Town of Truckee; and WHEREAS, the Town Council of the Town of Truckee makes the following express findings that said changes to the Codes are necessary because: The provisions contained in Town of Truckee Municipal Code Sections (hereinafter referred to as Section) 15.01.010 Purpose, 15.02.010 Utility Connections, 15.02.020 Final Inspection Enforcement, 15.02.040 Severability, 15.02.050 Penalties, 15.02.060 Fees, 15.02.070 Board of Appeals, are reasonably necessary to administratively adopt and enforce the codes and collect fees due to local conditions. Due to local climatic conditions of cold, rain and snow that shorten the building season, Section 15.03.010 Permit Expiration, provides an increased permit duration that is reasonably necessary to allow completion of construction projects. Page 4 of 25 Due to the local topographical conditions of the Town of Truckee being located in a mountainous region and to assure that buildings are properly situated on parcels of land, Section 15.03.030 Topographic Survey and Boundary Survey Requirements is determined to be reasonably necessary. Due to the local climatic condition of the Town of Truckee being declared a snow area and the associated high snow conditions, the following Sections are reasonably necessary to protect the life safety of the community and assure functional buildings. 15.02.030 Mobile Home Ramadas, 15.03.020 Engineering Requirement, 15.03.070 Sheet Metal Roofing Underlayment, 15.03.080 Declaration as High Snow Area, 15.03.090 Metal Valley Flashing Underlayment, 15.03.100 Ice Barriers, 15.03.110 Snow Loads, 15.03.120 Snow Load Design, 15.03.140 Chimneys, Protection from Sliding Snow,15.03.190 Protection of Exterior Wood Members against Decay, 15.04.030 Liquefied Petroleum Gas Facilities and Piping,15.05.010 Exit Terminals, and 15.05.020 Sidewall Venting.

Page 11 of 25 Title 15-6 2) A solar energy system that conforms to all applicable state fire, structural, electrical, and other building codes as adopted or amended by the Town, and paragraph (iii) of subdivision (c) of Section 714 of the Civil Code, as such section or subdivision may be amended, renumbered, or re-designated from time to time. 3) A solar energy system that is installed on a single or duplex family dwelling. 4) A solar panel or module array that does not exceed the maximum legal building height as defined by the authority having jurisdiction. “Solar energy system” has the same meaning set forth in paragraphs (1) and (2) of subdivision (a) of Section 801.5 of the Civil Code, as such section or subdivision may be amended, renumbered, or re-designated from time to time. (c) The Town’s building official is hereby authorized and directed to develop, adopt, and maintain a checklist of the requirements with which a small residential rooftop solar energy system project must comply in order to be entitled to expedited processing. The checklist shall be published on the Town’s website. (d) The applicant may submit the permit application and associated documentation to the Town’s building division by personal, mailed, or electronic submittal together with any required permit processing and inspection fees. In the case of electronic submittal, the electronic signature of the applicant on all forms, applications and other documentation may be used in lieu of a wet signature. (e) Prior to submitting an application, the applicant shall: 1) Verify to the applicant’s reasonable satisfaction through the use of standard engineering evaluation techniques that the support structure for the small residential rooftop solar energy system is stable and adequate to transfer all wind, seismic, and dead and live loads associated with the system to the building foundation; and 2) At the applicant’s cost, verify to the applicant’s reasonable satisfaction using standard electrical inspection techniques that the existing electrical system including existing line, load, ground and bonding wiring as well as main panel and subpanel sizes are adequately sized, based on the existing electrical system’s current use, to carry all new photovoltaic electrical loads. (f) For a small residential rooftop solar energy system eligible for expedited review, only one inspection shall be required, which shall be done in a timely manner and may include a consolidated inspection by the Town’s building official and a representative of the Truckee Fire Protection District. If a small residential rooftop solar energy system fails inspection, a subsequent inspection is authorized; however, the subsequent inspection need not conform to the requirements of this subsection. (g) An application that satisfies the information requirements in the checklist, as determined by the building official, shall be deemed complete. Upon receipt of an incomplete application, the building official shall issue a written correction notice detailing all deficiencies in the application and any additional information required to be eligible for expedited permit issuance. (h) Upon confirmation by the building official of the application and supporting documentation being complete and meeting the requirements of the checklist, the building official shall administratively approve the application and issue all required permits or authorizations. Such approval does not authorize an applicant to connect the small residential rooftop energy system to a utility provider’s electricity grid. The applicant is responsible for obtaining such approval or permission from the local utility provider. Page 12 of 25 Title 15-7 15.02.090 Expedited Permitting Process for Electric Vehicle Charging Systems (a) The intent of this section is to comply with the requirements of Government Code Section 65850.7 to promote and encourage the use of electric vehicles by creating an expedited, streamlined permitting process for electric vehicle charging stations while promoting public health and safety and preventing specific adverse impacts in the installation and use of such charging stations. (b) The following words and phrases as used in this section are defined as follows: “Electronic submittal” means a submittal made by email, the Internet, and/or facsimile. “Electric vehicle charging station” or “charging station” means any level of electric vehicle supply equipment station that is designed and built in compliance with Article 625 of the California Electrical Code, as it reads on the effective date of the ordinance adopting this section, and delivers electricity from a source outside an electric vehicle into a plug-in electric vehicle. (c) The Town’s building official is hereby authorized and directed to develop, adopt, and maintain a checklist of the requirements with which an expedited permitting process for electric vehicle charging systems project must comply in order to be entitled to expedited processing. The checklist shall be published on the Town’s website. (d) The applicant may submit the permit application and associated documentation to the Town’s building division by personal, mailed, or electronic submittal together with any required permit processing and inspection fees. In the case of electronic submittal, the electronic signature of the applicant on all forms, applications and other documentation may be used in lieu of a wet signature. (e) Prior to submitting an application, the applicant shall: 1) Verify to the applicant’s reasonable satisfaction through the use of standard engineering evaluation techniques that the support structure for the electric vehicle charging system is stable and adequate to transfer all wind, seismic, and dead and live loads associated with the system to the building foundation; and 2) At the applicant’s cost, verify to the applicant’s reasonable satisfaction using standard electrical inspection techniques that the existing electrical system including existing line, load, ground and bonding wiring as well as main panel and subpanel sizes are adequately sized, based on the existing electrical system’s current use, to carry all new electrical loads. 3) Verify that the installation of an electric vehicle charging station will not have specific, adverse impact to public health and safety and building occupants. Verification by the applicant includes but is not limited to: electrical system capacity and loads; electrical system wiring, bonding and overcurrent protection; building infrastructure affected by charging station equipment and associated conduits; areas of charging station equipment and vehicle parking. (f) An application that satisfies the information requirements in the checklist, as determined by the building official, shall be deemed complete and be promptly processed. Upon receipt of an incomplete application, the building official shall issue a written correction notice detailing all deficiencies in the application and any additional information required to be eligible for expedited permit issuance. (g) Upon confirmation by the Building Official that the permit application and supporting documents meets the requirements of the Town’s adopted checklist, and is consistent with all applicable laws and health and safety standards, the Building Official shall, consistent with Government Code Section 65850.7, approve the application and issue all necessary permits. Such approval does not authorize an applicant to energize or utilize the electric vehicle charging station until approval is granted by the Town of Truckee. Page 13 of 25 Title 15-8 (h) Consistent with Government Code Section 65850.7, the Building Official shall allow for electronic submittal of permit applications covered by this section and associated supporting documentations. In accepting such permit applications, the Building Official shall also accept electronic signatures on all forms, applications, and other documentation in lieu of a wet signature by any applicant. (i) It is the intent of this section to encourage the installation of electric vehicle charging stations by removing obstacles to permitting for charging stations so long as the action does not supersede the Building Official’s authority to address higher priority life-safety situations.

(11) Gas meter sheds shall be designed to resist 1.4 times the ground snow load, P g . (12) Decks located above the anticipated snow depth may be designed as flat roofs. The snow load for decks located below the anticipated snow depth may be interpolated between the roof and ground snow load based on the appropriate height. Consider impact, uplift and drift as appropriate. (g) Pitch reductions shall not apply to roofs where the eave line extends below the anticipated snow depth. "A-Frame" buildings and other similar types wherein the roof extends below the anticipated depth of the snow on the ground, the tabulated ground snow load values must be used on the roof below the ground snow level. Also, special design consideration must be made for the stress condition wherein the snow from the upper portion of the roof slides down on top of the ground snow and consequently further increases the loading on the lower portion of said roof. Page 18 of 25 Title 15-13 (h) Use of the “Unobstructed Slippery Surfaces” reduction in ASCE 7-16 Figure 7.4-1 is prohibited unless approved by the Building Official and the property is deed restricted to prevent future reroofing with a non-slippery material and future installations of snow guards (for snow retention). 15.03.120 Snow Load Design (a) Add the following to ASCE 7-16, Section 7.6.1 Unbalanced Snow Loads for Hip and Gable Roofs: (1) For roof pitches of less than or equal to 7/12 where the ground snow load (P g ) exceeds 100 psf, the unbalanced load (Pun) need not exceed: 0 psf at the ridge and hr*γ psf at the eave Where: hr = Vertical distance between the eave and ridge in feet γ = Density of the snow in pounds per cubic foot (pcf) This unbalanced load is determined from the maximum amount of drift snow that can accumulate on the leeward side of the roof. (A) Where the ground snow load (P g ) exceeds 100 psf and a pitch reduction is taken for the roof snow load, a valley load of 0.25*P s shall be added to the sloped roof snow load (P s ) in the influence area of all valleys created by intersecting roofs where the roof intersection angle is between 45 degrees and 90 degrees. For roof intersection angles less than 45 degrees design shall be in accordance with ASCE 7-16 section 7.6.3. (B) Valley and drift loads need not be applied concurrently.

In addition, a minimum of 50% of the roof snow load shall be considered on the roof up slope of the eave when this uniformly distributed load is applied. (E) Add the following to ASCE 7-16 section 7.9 Sliding Snow: (1) As an alternative, Appendix Chapter 16, Section 1644 of the 1997 UBC may be used to determine sliding snow. (F) Impact Load on Lower Structure. The load caused by snow sliding off a sloped upper roof onto a lower structure shall be determined for slippery upper roofs with slopes greater than 1/4 on 12, and for other (i.e. non- slippery) upper roofs with slopes greater than 2 on 12. The total impact load per unit length of the eave shall be: Upper roof (Pf or Ps) * Ii + Lower structure (Pf, Ps or Pg) See table below for Impact Factor Ii. The impact load shall be placed on the lower structure over a distance of 10 ft from the upper roof eave. Page 19 of 25 Title 15-14 Impact Factor Table Vertical Difference Between Upper Roof and Impact Surface of the Lower Structure1,2 Impact Factor I i Less than or equal to 0.5 h b on lower structure 0.0 Greater than 0.5 h b on lower structure but less than or equal to 10'- 0" 0.4 Greater than 10' - 0" but less than or equal to 18' - 0" 1.0 Greater than 18' - 0" Special Analysis Required 1 The Impact Surface may be taken as the top of the snow on the lower structure. 2 Rebound loads shall be considered.
