The standards in this Chapter apply to the construction or installation of detached single-family residential structures where allowed in compliance with Division 2 (Land Use Zoning Districts and Allowed Land Uses). However, nothing in this Chapter shall be construed to allow housing designs or construction standards that do not meet the standards of a historic district or of a historic landmark. The road dedication and street improvement standards provided in this Chapter do not apply to: (1) the alteration or enlargement of an existing building or structure on a lot or parcel of land if the total square footage of such alteration or enlargement, and all other alterations or enlargements completed three years prior to the date of the application for a permit for such alteration or enlargement, does not exceed one-half of the original square footage of all buildings and structures on such lot or parcel of land, or (2) the erection of one or more accessory structures (not including accessory dwellings) as defined in § 810.01.030(g) of the County Code. For purposes of this section, “original square footage” means the square footage of all buildings and structures that existed on such lot or parcel of land three years prior to the date of the application for such permit.
