Enacts GS 160D-915.1 to authorize local governments to establish a process to permit temporary event venues, defined as an existing publicly or privately owned building or structure suitable for use as a site for public or private events relating to entertainment, education, marketing, meetings, sales, trade shows, and any other activities or occasions authorized by government ordinance, and limited to 72 hours. Defines local government to mean a municipality with a population of 100,000 or more. Allows the temporary event venue to be considered as a permitted accessory use in any zoning district and not considered a zoning map amendment; bars requiring a special use permit or subjection to other local zoning requirements. Allows only one temporary event venue per lot or parcel of land, and limits permitted venues to 24 temporary events in a calendar year. Details requirements for ordinances authorizing temporary event venues, including prescribing the process for persons seeking a temporary event venue permit or a renewal. Specifies that issuance of a temporary event venue permit is not a quasi-judicial act. Allows local governments to charge up to $100 for an initial permit and up to $50 for a renewal. Allows the local government to require any concerns from the required inspection to be addressed with reasonable measures and to require the use of temporary toilet facilities. Exempts permitted temporary event venues from requirements of the Building Code or any local variants. Requires compliance with federal laws and regulations. Provides parameters for instances in which permittees seek rezoning of the parcel to a zoning district that would allow a permitted use of the venue for events of the type authorized by a temporary event permit. Makes conforming changes to GS 143-138 (concerning the State Building Code). Effective October 1, 2023.
