The regulations contained in this subchapter shall apply to all lands in the unincorporated county.
(A) Every legal lot of record and lot in a proposed land subdivision, within a geologic hazard study area as defined by this subchapter, must have a buildable area safe for the intended use. Each buildable area must also have access from the nearest existing public or private street which is free of unreasonable and unacceptable geologic hazards. Any geologic hazards which must be mitigated in order to provide a buildable area with acceptable and reasonable access must be mitigated prior to issuance of the final plat recordation.
(B) Detached accessory buildings which are not designed for human occupancy are not required to comply with the provisions of this subchapter. Also, the remodeling of existing structures designed for human occupancy may occur without compliance with this subchapter, if no expansion of the existing structure footprint and no structure use change is proposed. Complete demolition and replacement of structures shall comply with this subchapter. Other properties may also be exempt from certain study requirements, as identified in § 155.236 of this code.
(C) As defined in the currently statewide adopted 2018 International Building Code (IBC), Table 1604.5, the county considers IBC Risk Category III buildings and other structures to represent a substantial hazard to human life in the event of failure, except that any structure with an occupancy greater than 1,000 shall also be considered IBC Risk Category III when not meeting the criteria for IBC Risk Category IV; and IBC Risk Category IV buildings and other structures are designated as essential (critical) facilities.
