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 Mammoth Lakes 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.

Consistent with Government Code § 65850.7, the Building Official shall implement an expedited administrative permit review process for electric vehicle charging stations and adopt a checklist of all requirements with which electric vehicle charging stations shall comply with in order to be eligible for expedited review. The expedited administrative permit review process and checklist may refer to the recommendations in the checklist prescribed by the most current version of the Plug-In Electric Vehicle Infrastructure Permitting Checklist of the Zero-Emission Vehicles in California: Community Readiness Guidebook published by the Governor's Office of Planning and Research. The Town's adopted checklist shall be published on the Town's website.

If the Building Official determines that the permit application is incomplete, said official shall issue a written correction notice to the applicant, detailing all deficiencies in the application and any additional information required to be eligible for expedited permit issuance.

(j)

Technical review. 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. If the Building Official makes a finding based on substantial evidence that the electric vehicle charging station could have a specific adverse impact upon the public health or safety, as defined in Government Code § 65850.7, the Town may require the applicant to apply for a use permit.

Amendments to the 2025 California Building Standards Code.

Amendment Section Amendment Justification (see below key to justifications)

Justifications key: Findings to Support Amendments to California Building Standards Code.

A. This amendment is necessary for administrative clarification and does not modify a building standard pursuant to California Health and Safety Code §§ 17958, 17958.7 and/or 18941.5. This amendment establishes administrative standards for the effective enforcement of the building standards in the Town of Mammoth Lakes.

B. This amendment is reasonably necessary because of the following local climatic conditions:

(i) During the winter the Town experiences of periods of very cold temperatures accompanied by periods of significant snowfall and high winds; and

(ii) During the summer months relatively hot temperatures with periods of low humidity and high winds. The vegetative environment surrounding the Town varies from meadow/high desert vegetation communities (grass/brush) to densely populated stands of timber.

(iii) These conditions require building conditions suitable for these wildland environments.

C. This amendment is reasonably necessary because of the following local geological conditions:

(i) The Town is within an active seismic/volcanic area; and

(ii) A significant earthquake could render emergency responders incapable of providing adequate emergency response.

D. This amendment is reasonably necessary because of the following local topographical conditions:

(i) The Town is located in a geographically challenging environment with elevations ranging from approximately 7,500 feet to over 11,000 feet. Slopes vary from relatively flat to hillsides exceeding 60 degrees; and these conditions require building conditions addressing these challenges.
