The provisions of this chapter shall apply to all properties within the Schieffelin historic preservation district and any property designated as having historic significance within the Tombstone city limits, following the nomination and designation procedures specified in this chapter, provided that when one or more than one property owners are included in the proposed designated district, support of a majority of property owners of record, based on linear street frontage, within the boundaries of the proposed district or districts, must be submitted to the commission before final acceptance as a designated district. Such support shall be ascertained by a survey of said property owners, by the commission, or by written consent of fifty one percent (51%) of the property owners of record within the boundaries of the proposed designated district to be submitted with the application. Subsequent to the establishment of an initial designated district, or districts, other historic properties and districts may be added in the future upon application of the owner of said historic property, or of a majority of property owners within said district, following the same procedures specified in this chapter.
