Section 120 - Expedited permit process for small residential rooftop solar systems.

Purpose and Intent. The purpose of this section is to provide an expedited, streamlined solar permitting process that complies with the Solar Rights Act and AB 2188 (Chapter 521, Statutes 2014, California Government Code Section 65850.5) in order to achieve timely and cost-effective installations of small residential rooftop solar energy systems. This section encourages the use of solar systems by removing unreasonable barriers, minimizing costs to property owners and the county, and expanding the ability of property owners to install solar energy systems. This section allows the county to achieve these goals while protecting the public health and safety.

Definitions. As used in this section:

"Electronic submittal"

means the utilization of electronic e-mail or submittal via the internet.

"Reasonable restrictions"

on a solar energy system are those restrictions that do not significantly increase the cost of the system or significantly decrease its efficiency or specified performance, or that allow for an alternative system of comparable cost, efficiency, and energy conservation benefits.

"Restrictions that do not significantly increase the cost of the system or decrease its efficiency or specified performance"

means:

For water heater systems or solar swimming pool heating systems: an amount exceeding 10% of the cost of the system, but in no case more than $1,000, or decreasing the efficiency of the solar energy system by an amount exceeding 10%, as originally specified and proposed.

For photovoltaic systems: an amount not to exceed $1,000 over the system cost as originally specified and proposed, or a decrease in system efficiency of an amount exceeding 10% as originally specified and proposed.

"Small residential rooftop solar energy system"

means all of the following:

A solar energy system that is no larger than 10 kilowatts alternating current nameplate rating or 30 kilowatts thermal.

A solar energy system that conforms to all applicable state fire, structural, electrical, and other building codes as adopted or amended by the county and paragraph (iii) of subdivision (c) of Section 714 of the Civil Code, as such section or subdivision may be amended, renumbered, or designated from time to time.

A solar energy system that is installed on a single- or duplex-family dwelling.

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 designated from time to time.

"Specific adverse impact"

means a significant, quantifiable, direct, unavoidable impact, based on objective, identified, and written public health or safety standards, policies, or conditions as they existed on the date the application was deemed complete.

Applicability.

This section applies to the permitting of all small residential rooftop solar energy systems under the jurisdiction of the county.

Small residential rooftop solar energy systems legally established or permitted prior to the effective date of the ordinance codified in this section are not subject to the requirements of this section unless physical modifications or alterations are undertaken that materially change the size, type, or components of a small rooftop energy system in such a way as to require new permitting. Routine operation and maintenance or like-kind replacements shall not require a permit.

Solar Energy System Requirements.

All small residential rooftop solar energy systems shall meet applicable health and safety standards and requirements imposed by the state and the county.

Solar energy systems for heating water in single-family residences shall be certified by an accredited listing agency as defined by the California Plumbing and Mechanical Code.

Solar energy systems for producing electricity shall meet all applicable safety and performance standards established by the California Electrical Code, the Institute of Electrical and Electronics Engineers, and accredited testing laboratories such as Underwriters Laboratories and, where applicable, rules of the Public Utilities Commission regarding safety and reliability.

Applications and Documents.

All documents required for the submission of an expedited solar energy system application shall be made available on the county website.

Electronic submittal of the required permit application and documents by email or the Internet shall be made available to all small residential rooftop solar energy system permit applicants.

The county's building services division shall adopt and post on the county's website a standard plan and checklist of all requirements ("Expedited Application Requirements") with which small residential rooftop solar energy systems shall comply to be eligible for expedited review. Said plan and checklist shall substantially conform to recommendations for expedited permitting, including the checklist and standard plans contained in the most current version of the California Solar Permitting Guidebook adopted by the Governor's Office of Planning and Research.

Prior to submitting an application, the applicant shall:

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

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.

Permit Review and Inspection Requirements.

An application that satisfies all the requirements of the expedited application requirements, as determined by the chief building official or designee shall be deemed complete.

Once deemed complete, the building services division shall issue a building permit, the issuance of which is nondiscretionary, on the same day for over-the-counter applications or within one to three business days for electronic applications. The issuance of said permit does not authorize an applicant to connect the small residential rooftop energy system to the local utility provider's electricity grid until inspected and authorization to do so is demonstrated by the chief building official or designee. The applicant is further responsible for obtaining such approval or permission to connect from the local utility provider.

Only one inspection shall be required and performed by the building services division for small residential rooftop solar energy systems eligible for expedited review. The inspection shall be done in a timely manner and may include a consolidated inspection by the building official and fire chief, and/or their designated representatives. 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.

If the building official determines an application is incomplete, the chief building official or designee shall issue a written correction notice detailing all deficiencies in the application and any additional information or documentation required to be eligible for expedited permit issuance. Said written correction notice shall be issued within five business days of the date of determination of an incomplete application.

The chief building official or designee may require an applicant to apply for a limited review permit if the official finds, based on substantial evidence, that the solar energy system could have a specific, adverse impact upon the public health and safety. Such decision may be appealed by the applicant to the CDRA director subject to the provisions of subsection G.

If a limited review permit is required, the chief building official may deny such application if it makes written findings based upon substantive evidence in the record that the proposed installation would have a specific, adverse impact upon public health or safety and there is no feasible method to satisfactorily mitigate or avoid, as defined, the adverse impact. "A feasible method to satisfactorily mitigate or avoid the specific, adverse impact" includes, but is not limited to, any cost-effective method, condition, or mitigation imposed by the county on another similarly situated application in a prior successful application for a permit. The county shall use its best efforts to ensure the selected method, condition, or mitigation meets the conditions of subparagraphs (A) and (B) of paragraph (1) of subdivision (d) of Section 714 of the Civil Code defining restrictions that do not significantly increase the cost of the system or decrease its efficiency or specified performance. Such findings shall include the basis for the rejection of the potential feasible alternative for preventing the adverse impact. Such decision may be appealed by the applicant to the CDRA director subject to the provisions of subsection G.

Any condition imposed on an application shall be designed to mitigate the specific, adverse impact upon health and safety at the lowest possible cost.

Appeals.

The applicant may appeal decisions rendered pursuant to subsection (F)(4) or (F)(5) upon payment of the appeal fee, submittal of an appeal application to the CDRA front counter within 10 calendar days of the date of the decision.

The decision of the CDRA director on an appeal is final.

Where Pg is 100 pounds per square foot or greater, an ice barrier is required for the roofing materials as noted in CBC section 1507.

Note: Occasionally there may be large local deviations from the typical data from which this code was developed. When applying these values to structures, the designer should make every effort to determine if the tabulated values should be adjusted because of local topographic or climatic effects. Loads for structures which have an inherent need for a high degree of safety, or a long life span, should be carefully evaluated, and the designer should always exercise their best professional judgment. These snow load and design requirements are minimum requirements.

Roof and snow loads for all manufactured homes, manufactured home accessory buildings, commercial coaches, and factory built housing shall comply with the snow loading for other structures. (Exception: manufactured homes in mobile home parks and manufactured homes where Pg is less than 100 pounds per square foot shall comply with Title 25 of the California Code of Regulations.)

Notice to Builders—Warning. New structures which are in a partially completed state during the winter months will probably experience severe damage from snow, ice, and wind. It will be the responsibility of the permittee to ensure that his or her partially completed structure is such as to resist all of the winter weather elements of Placer County.

Section R301.2.2.1.1 - Alternate determination of seismic design category. Add the following to Section R301.2.2.1.1 of the CRC:

Structures which otherwise qualify for conventional construction may utilize soil profile types C or D based on the design professional’s assessment of the site in combination with public record maps, such as maps from the California Geological Survey. This does not apply where a soils report identifies conditions sufficient to classify the site as E or F as defined in the 2022 CBC and CRC.

Section R301.2.3 - Snow loads. Replace Section R301.2.3 of the CRC with the following section:

Section R301.2.3 - Snow loads.

Design requirements for conventional construction structures: Structures normally governed by section 2308 of the CBC, which are located in areas where the ground snow load (Pg) exceeds 50 pounds per square foot (P.S.F.), shall have both the gravity and lateral structural system designed by duly licensed design professional(s). Such structures, which otherwise qualify for conventional light frame construction in Section 2308 of the CBC, may utilize soil profile types of C or D based on the design professional's assessment of the site in combination with public record maps, such as maps from the California Geological Survey. This does not apply where a soils report has identified soils conditions sufficient to classify the soil type as E or F as defined in the 2022 California Building Code.

Design seismic loading for snow loads shall comply with the current ASCE-7 Standards.

Where Pf is greater than or equal to 30 P.S.F., all building exits shall be protected or located where not subject to sliding or impact snow and ice. "All building exits" shall mean all required exits in single family dwellings and appurtenant structures, and all building exits in all other occupancies.

All unheated overhangs shall be designed for ice dams and accumulation per the current ASCE-7 Standards. Heat strips or other exposed heat methods may not be used in lieu of this design.

Where Pg is 100 P.S.F. or greater, an ice barrier is required for the roofing materials as noted in CBC section 1507.1.2 and CRC Section R905.2.7.

Note: Occasionally there may be large local deviations from the typical data from which this code was developed. When applying these values to structures, the designer should make every effort to determine if the tabulated values should be adjusted because of local topographic effects. Loads for structures which have an inherent need for a high degree of safety, or a long life span, should be carefully evaluated, and the designer should always exercise their best professional judgment. These snow load and design requirements are minimum requirements.

Roof and snow loads for all manufactured homes, manufactured home accessory buildings, commercial coaches, and factory built housing shall comply with the snow loading for other structures. (Exception: manufactured homes in mobile home parks and mobile homes where Pg is less than 100 P.S.F. shall comply with California Code of Regulations, Title 25.)
