For the purposes of regulating and restricting the location of trades, industries, apartment houses and other uses of property, the number of square feet of lots per family housed, the location and size of yards and height of buildings in the developed portion of the City, the City is hereby divided into zones or districts, as shown on the Official Zoning Map which, together with all explanatory matter thereon, is hereby adopted by reference and incorporated as a part of this chapter. The Official Zoning Map shall be identified by the signature of the Mayor, attested by the City Clerk and bearing the seal of the City under the following words: "This is to certify that this is the Official Zoning Map referred to in section 5-4-3 of the Zoning Ordinance of the City of Isle of Palms, S.C., adopted on (date of adoption)." If, in accordance with the provisions of this chapter, changes are made in district boundaries or other matter portrayed on the Official Zoning Map, such changes shall be made on the Official Zoning Map promptly after the amendment has been approved by City Council, with an entry on the Official Zoning Map as follows: "On (date), by official action of the City Council, the following changes were made (change was made) in the Official Zoning Map; (brief description of change)" which entry shall be signed by the Mayor and shall be attested by the City Clerk. No such change shall become effective until such entry shall have been made on the Official Zoning Map, and signed and attested. Regardless of the existence of purported copies of the Official Zoning Map which may from time to time be made or published, the Official Zoning Map shall be in the custody of the City Administrator and shall be the final authority as to the current zoning status of lands, buildings, and other structures in the City. In the event that the Official Zoning Map becomes damaged, destroyed, lost or difficult to interpret by reason of the nature of number of changes and additions, the City Council may by ordinance adopt a new Official Zoning Map which shall supersede the prior Official Zoning Map. The new Official Zoning Map may correct drafting and other errors or omissions in the prior Zoning Map, but no such correction shall have the effect of amending the original Official Zoning Map as amended. The new Official Zoning Map shall be marked "This is the Official Zoning Map, adopted (date), of the City of Isle of Palms, S.C." which statement shall be signed by the Mayor, attested by the City Clerk, and bear the seal of the City. Unless the prior Official Zoning Map is lost or has been totally destroyed, the map or any significant parts thereof remaining after partial destruction shall be preserved, together with all records of the City regarding its adoption and amendment. No structure or premises shall be erected or used except in conformity with the regulations prescribed in this chapter for use, height and area districts in which such structure or premises is located.
(Code 1994, § 5-4-3)

Where the streets or alleys on the ground differ from the streets or alleys as shown on the map, the Zoning Administrator may apply the district designations on the map to the streets or alleys on the ground in such manner as to conform to the intent and purpose of this chapter.
(Code 1994, § 5-4-4)
(a)
Appeals.
1.
Pursuant to S.C. Code 1976, § 6-29-780, the City Board of Zoning Appeals is hereby established. Provisions relating to organization, composition and functions of the Board are set forth in title 1, chapter 9, article B. Appeals to the Board of Zoning Appeals may be taken from any order or decision of the Zoning Administrator by any person aggrieved or by any officer, department, or board of the City. Unless otherwise provided by rules of the Board, an appeal must be made by written application setting forth the grounds of appeal and filed with the Zoning Administrator within thirty (30) days from the date of the order or decision appealed from. The Zoning Administrator shall promptly forward to the Board all documents constituting the record upon which the action appealed from was taken. The Board shall fix a reasonable time for the hearing of the appeal or other matter referred to it, and give at least fifteen (15) days' public notice thereof in a newspaper of general circulation in the community and also due notice to the parties in interest, and decide the same within a reasonable period of time. At the hearing, any party may appear in person or by agent or attorney. The Board shall adopt rules of procedure for the conduct of hearings. All final decisions and orders of the Board shall be in writing and permanently filed in the office of the Board as a public record. All findings of fact and conclusions of law must be separately stated in final decisions or orders of the Board, which must be delivered to parties in interest by certified mail.
2.
An appeal stays all legal proceedings in furtherance of the action appealed from, unless the officer from whom the appeal in taken certifies to the Board, after the notice of appeal has been filed with him, that by reason of facts stated in the certificate a stay would, in his opinion, cause imminent peril to life and property. In such case, proceedings may not be stayed other than by a restraining order which may be granted by the Board or by a court of record on application, on notice to the officer from whom the appeal is taken, and on due cause shown.
(b)
Variances. Pursuant to S.C. Code 1976, § 6-29-800, upon written application filed with the Zoning Administrator, the Board may authorize in specific cases a variance from the terms of the ordinances contained in this chapter when strict application of the provisions of the ordinance would result in unnecessary hardship. Filing fees set by resolution of City Council from time to time must be paid by the applicant at the time of filing of an application for a variance. Such application shall contain information addressing each of the statutory requirements for variances stated in S.C. Code 1976, § 6-29-800, as amended, all of which must be met. A variance may be granted in an individual case of unnecessary hardship if the Board makes and explains in writing the following findings:
(1)
There are extraordinary and exceptional conditions pertaining to the particular piece of property;
(2)
Such conditions do not generally apply to other property in the vicinity;
(3)
Because with these conditions, the application of the ordinance or resolution of the particular piece of property would effectively prohibit or unreasonably restrict the utilization of the property;
(4)
The authorization of a variance will not be of substantial detriment to an adjacent property or to the public good, and the character of the district will not be harmed by the granting of the variance.
The Board may not grant a variance which has the effect of allowing the establishment of a use not otherwise permitted in a zoning district, to physically extend a nonconforming use, or to change the zoning district boundaries shown on the official zoning map. The fact that property may be utilized more profitably if a variance were granted shall not be considered as a ground for a variance. A claim of unnecessary hardship cannot be based on conditions created by the applicant. A claim of unnecessary hardship cannot be based on financial hardship of the applicant.
In granting a variance, the Board may attach to it such conditions regarding the location, character, or other features of the proposed building, structure, or use as the Board may consider advisable to protect established property values in the surrounding area, or to promote the public health, safety, or general welfare.
(c)
Special exceptions.
1.
Upon written application filed with the Zoning Administrator, the Board may grant as a special exception any use specified as a special exception in the zoning district regulations. In addition to the conditions generally required by the applicable zoning district regulations, the Board shall apply the following standards in deciding special exception applications:
(1)
Adequate provision shall be made for setbacks, fences, buffer or planting strips to protect adjacent properties from adverse impact of the proposed use, such as noise, vibration, dust, glare, odor, traffic congestion and similar factors.
(2)
Vehicular traffic and pedestrian movement on adjacent roads must not be hindered or endangered.
(3)
Off-street parking and loading areas and the entrances and exits for the use must be adequate in terms of location, number, design and construction to serve the use without adverse impact on adjacent properties.
(4)
The proposed use must not adversely affect the property values, the general character or the general welfare of the surrounding vicinity.
2.
In granting a special exception, the Board may attach to it such conditions regarding the location, size, character, or other features of the proposed use as the Board may consider advisable in order to promote public health, safety, or general welfare. No special exception use may be altered or enlarged without the prior approval of the Board.

For the purposes of regulating and restricting the location of trades, industries, apartment houses and other uses of property, the number of square feet of lots per family housed, the location and size of yards and height of buildings in the developed portion of the City, the City is hereby divided into zones or districts, as shown on the Official Zoning Map which, together with all explanatory matter thereon, is hereby adopted by reference and incorporated as a part of this chapter. The Official Zoning Map shall be identified by the signature of the Mayor, attested by the City Clerk and bearing the seal of the City under the following words: "This is to certify that this is the Official Zoning Map referred to in section 5-4-3 of the Zoning Ordinance of the City of Isle of Palms, S.C., adopted on (date of adoption)." If, in accordance with the provisions of this chapter, changes are made in district boundaries or other matter portrayed on the Official Zoning Map, such changes shall be made on the Official Zoning Map promptly after the amendment has been approved by City Council, with an entry on the Official Zoning Map as follows: "On (date), by official action of the City Council, the following changes were made (change was made) in the Official Zoning Map; (brief description of change)" which entry shall be signed by the Mayor and shall be attested by the City Clerk. No such change shall become effective until such entry shall have been made on the Official Zoning Map, and signed and attested. Regardless of the existence of purported copies of the Official Zoning Map which may from time to time be made or published, the Official Zoning Map shall be in the custody of the City Administrator and shall be the final authority as to the current zoning status of lands, buildings, and other structures in the City. In the event that the Official Zoning Map becomes damaged, destroyed, lost or difficult to interpret by reason of the nature of number of changes and additions, the City Council may by ordinance adopt a new Official Zoning Map which shall supersede the prior Official Zoning Map. The new Official Zoning Map may correct drafting and other errors or omissions in the prior Zoning Map, but no such correction shall have the effect of amending the original Official Zoning Map as amended. The new Official Zoning Map shall be marked "This is the Official Zoning Map, adopted (date), of the City of Isle of Palms, S.C." which statement shall be signed by the Mayor, attested by the City Clerk, and bear the seal of the City. Unless the prior Official Zoning Map is lost or has been totally destroyed, the map or any significant parts thereof remaining after partial destruction shall be preserved, together with all records of the City regarding its adoption and amendment. No structure or premises shall be erected or used except in conformity with the regulations prescribed in this chapter for use, height and area districts in which such structure or premises is located.
(Code 1994, § 5-4-3)

Where the streets or alleys on the ground differ from the streets or alleys as shown on the map, the Zoning Administrator may apply the district designations on the map to the streets or alleys on the ground in such manner as to conform to the intent and purpose of this chapter.
(Code 1994, § 5-4-4)
(a)
Appeals.
1.
Pursuant to S.C. Code 1976, § 6-29-780, the City Board of Zoning Appeals is hereby established. Provisions relating to organization, composition and functions of the Board are set forth in title 1, chapter 9, article B. Appeals to the Board of Zoning Appeals may be taken from any order or decision of the Zoning Administrator by any person aggrieved or by any officer, department, or board of the City. Unless otherwise provided by rules of the Board, an appeal must be made by written application setting forth the grounds of appeal and filed with the Zoning Administrator within thirty (30) days from the date of the order or decision appealed from. The Zoning Administrator shall promptly forward to the Board all documents constituting the record upon which the action appealed from was taken. The Board shall fix a reasonable time for the hearing of the appeal or other matter referred to it, and give at least fifteen (15) days' public notice thereof in a newspaper of general circulation in the community and also due notice to the parties in interest, and decide the same within a reasonable period of time. At the hearing, any party may appear in person or by agent or attorney. The Board shall adopt rules of procedure for the conduct of hearings. All final decisions and orders of the Board shall be in writing and permanently filed in the office of the Board as a public record. All findings of fact and conclusions of law must be separately stated in final decisions or orders of the Board, which must be delivered to parties in interest by certified mail.
2.
An appeal stays all legal proceedings in furtherance of the action appealed from, unless the officer from whom the appeal in taken certifies to the Board, after the notice of appeal has been filed with him, that by reason of facts stated in the certificate a stay would, in his opinion, cause imminent peril to life and property. In such case, proceedings may not be stayed other than by a restraining order which may be granted by the Board or by a court of record on application, on notice to the officer from whom the appeal is taken, and on due cause shown.
(b)
Variances. Pursuant to S.C. Code 1976, § 6-29-800, upon written application filed with the Zoning Administrator, the Board may authorize in specific cases a variance from the terms of the ordinances contained in this chapter when strict application of the provisions of the ordinance would result in unnecessary hardship. Filing fees set by resolution of City Council from time to time must be paid by the applicant at the time of filing of an application for a variance. Such application shall contain information addressing each of the statutory requirements for variances stated in S.C. Code 1976, § 6-29-800, as amended, all of which must be met. A variance may be granted in an individual case of unnecessary hardship if the Board makes and explains in writing the following findings:
(1)
There are extraordinary and exceptional conditions pertaining to the particular piece of property;
(2)
Such conditions do not generally apply to other property in the vicinity;
(3)
Because with these conditions, the application of the ordinance or resolution of the particular piece of property would effectively prohibit or unreasonably restrict the utilization of the property;
(4)
The authorization of a variance will not be of substantial detriment to an adjacent property or to the public good, and the character of the district will not be harmed by the granting of the variance.
The Board may not grant a variance which has the effect of allowing the establishment of a use not otherwise permitted in a zoning district, to physically extend a nonconforming use, or to change the zoning district boundaries shown on the official zoning map. The fact that property may be utilized more profitably if a variance were granted shall not be considered as a ground for a variance. A claim of unnecessary hardship cannot be based on conditions created by the applicant. A claim of unnecessary hardship cannot be based on financial hardship of the applicant.
In granting a variance, the Board may attach to it such conditions regarding the location, character, or other features of the proposed building, structure, or use as the Board may consider advisable to protect established property values in the surrounding area, or to promote the public health, safety, or general welfare.
(c)
Special exceptions.
1.
Upon written application filed with the Zoning Administrator, the Board may grant as a special exception any use specified as a special exception in the zoning district regulations. In addition to the conditions generally required by the applicable zoning district regulations, the Board shall apply the following standards in deciding special exception applications:
(1)
Adequate provision shall be made for setbacks, fences, buffer or planting strips to protect adjacent properties from adverse impact of the proposed use, such as noise, vibration, dust, glare, odor, traffic congestion and similar factors.
(2)
Vehicular traffic and pedestrian movement on adjacent roads must not be hindered or endangered.
(3)
Off-street parking and loading areas and the entrances and exits for the use must be adequate in terms of location, number, design and construction to serve the use without adverse impact on adjacent properties.
(4)
The proposed use must not adversely affect the property values, the general character or the general welfare of the surrounding vicinity.
2.
In granting a special exception, the Board may attach to it such conditions regarding the location, size, character, or other features of the proposed use as the Board may consider advisable in order to promote public health, safety, or general welfare. No special exception use may be altered or enlarged without the prior approval of the Board.
