Sec. 24-8.1.- Application of regulations.

The various zoning district regulations established herein are declared to be the minimum requirements necessary to carry out the purpose of this chapter. These regulations apply to each class or kind of structure or land, and are the minimum standards for all site clearing, development, buildings, structures, or alterations to land or structures within the jurisdiction of this chapter.

No part of a setback, open space, or off-street parking required in connection with any building for the purpose of complying with the regulations of this chapter shall be included as part or all of the required setback, open space, or off-street parking for another building or structure, except as hereinafter provided.

(Ord. No. 07-6-12, § 5, 6-5-07)

Sec. 24-8.2. - Exceptions and modifications.

(1)

Setbacks—Corner lots. The setback from the street upon which the principal building will face shall be the minimum required front setback. The setback from the street upon which the side of the building will face also shall meet the minimum front setback requirements for the district within which the lot is located. The minimum side setback requirements for the district within which the lot is located shall be provided along all other lot lines.

(2)

Setbacks—Through or double frontage lots. Front setbacks for double frontage lots shall be provided for both streets upon which the lot has frontage, and any accessory use(s) shall be prohibited from the required front setback of the street upon which the principal building fronts.

(3)

Setbacks—Partially developed areas. The front-setback requirements for dwellings shall not apply on any lot where the average setback of existing buildings located wholly or in part within two hundred (200) feet on each side of such lot within the same block and zoning district and fronting on the same side of the street is less than the minimum required setback. In such cases, the setback on such lot may be less than the required setback, but not less than the average of the setbacks of the aforementioned existing buildings, as shown below:

(4)

Setbacks—Multiple buildings on lot.

Any fences and/or walls greater than six (6) feet in height erected on any property shall be approved by the building official.

All fences and walls erected on any property must have a finished side that faces the adjoining property. The interior side of the fence or wall may be finished as the applicant or owner deems appropriate. Where fences and/or walls are proposed by the applicant or owner, but not required by the applicable bufferyard requirements, such fences and/or walls shall be established along the inside line of the bufferyard, toward the proposed use, except for ornamental fences or fences to the rear of the property, which may be built on the property line. Security fences and walls also may be established along the outer perimeter of the lot, in compliance with this section 8.2.6 and section 8.5.

(Ord. No. 07-6-12, § 5, 6-5-07; Ord. No. 07-11-25, § 1, 11-27-07; Ord. No. 08-4-17, § 1, 4-1-08; Ord. No. 09-08-17, § 1(LMR 6), 8-18-09; Ord. No. 14-12-18, § 1, 12-9-14; Ord. No. 21-09-23, § 1, 9-21-21)

Sec. 24-8.7.1. - Continuation.

Nonconforming uses, buildings, or structures are declared by this chapter to be incompatible with permitted uses in the districts in which they are located. However, to avoid undue hardship, the lawful use of any such use, building, or structure at the time of the enactment, amendment, or revision of this chapter and/or the ZDSO may be continued ("grandfathered") even though such use, building, or structure does not conform with the provisions of this chapter.

Nonconforming uses shall be allowed to continue on the parcel on which they were located at the time of adoption of this chapter as long as the size of that property parcel is not increased or the nonconforming use is not expanded onto adjoining property parcels. For example, nonconforming manufactured home parks shall be limited to the number of manufactured homes originally approved for the park by the county or by the State of South Carolina. Similarly, nonconforming wrecking yards, junkyards and salvage yards shall be limited to the parcel or parcels on which such uses were located at the time of enactment, amendment, or revision of this chapter.

(Ord. No. 07-6-12, § 5, 6-5-07; Ord. No. 12-04-08, § 1, 4-17-12)

Sec. 24-8.7.2. - Modification.

A proposed change or modification to a nonconforming use shall be governed by the following:

(1)

Change of nonconforming use. If a change from one nonconforming use to another is proposed and no structural alterations are involved, the change may be permitted, provided:

a.

Nonconformity of dimensional requirements such as height, density, setbacks, or other requirements such as off-street parking shall not be increased; and

b.

The new nonconforming use shall not present an increase in the degree of nonconformity from the preceding use. The following factors shall be considered in determining whether a new use increases the degree of nonconformity: required number of parking spaces, hours of operation, nature of business or land use, bufferyard requirements, noise generated, or other standards relevant to the proposed business or use.

If a change to a permitted use is proposed which is nonconforming only as to dimensional requirements such as height, density, setbacks, or other requirements such as off-street parking, the change may be permitted, provided that all applicable requirements that can be reasonably complied with are met.

For example, compliance with a requirement is not reasonably possible if it requires adding land to the lot of the nonconforming use or moving the use if it is on a permanent foundation.

Whenever a nonconforming use of land or building has been changed to a more restrictive use or to a conforming use, such use shall not thereafter be changed back to a less-restricted or nonconforming use.

(2)

Repair or alteration of nonconforming use, building or structure. The repair or alteration of a nonconforming use shall in no way increase the nonconformity of said use, except as otherwise permitted by subsection (1)b above.

(3)

Replacement and/or reconstruction of nonconforming use.

a.

A nonconforming building or structure may be replaced or reconstructed to the extent of fifty (50) percent of its appraised value. A building permit for the replacement or reconstruction of a nonconforming building or structure once removed, damaged or destroyed must be initiated within one hundred eighty (180) days or the right of replacement shall be forfeited.

b.

Replacement may occur within the original building "footprint"; provided the replacement structure shall in no way increase the nonconformity of said use, except as otherwise permitted by subsections 1.b and 2 above.

c.

Replacement of a nonconforming mobile or manufactured home not located in a manufactured home park, once removed from a lot or parcel, shall be accomplished within one hundred eighty (180) days of removal or forfeit nonconforming status shall be forfeited, and if the mobile or manufactured home is replaced it shall not infringe on established setbacks, and shall meet in full the requirements of section 24-3.14 of this chapter. Mobile or manufactured homes located in nonconforming manufactured home parks may be replaced without time limitations provided the total number of units in the park does not exceed the total number for which the park was approved at the time of enactment, amendment, or revision of this chapter. Nonconforming standard-design manufactured dwellings may be replaced by residential-design manufactured dwellings as long as any existing nonconformity with required setbacks is not increased.

(Ord. No. 07-6-12, § 5, 6-5-07)

Sec. 24-8.7.3. - Discontinuance.

No building or parcel of land, nor any portion of any building or parcel of land used in whole or in part for a nonconforming use which remains idle or unused for a continuous period of five hundred forty (540) days, whether or not the equipment or fixtures are removed, shall be used again except in conformity with the regulations of the district in which such building or land is located.

(Ord. No. 07-6-12, § 5, 6-5-07)

Sec. 24-8.7.4. - Proof of nonconformity.

When seeking relief under section 24-8.7 it shall be the responsibility of the owner, manager or tenant of a nonconforming use to establish existence of such use prior to the effective date of this chapter.

(Ord. No. 07-6-12, § 5, 6-5-07)

Sec. 24-8.7.5. - Lot of record.

Where the owner of a lot at the time of the adoption of this chapter does not own sufficient land to enable him to conform to the setback requirements of this chapter, such lot may nonetheless be used as a building site provided applicable setback requirements are not reduced by more than twenty (20) percent. Setback reductions greater than twenty (20) percent shall be referred to the board of appeals for consideration. If, however, the owner of two (2) or more adjoining lots with insufficient land dimensions decides to build on or sell off these lots, they must first be combined to comply with the dimensional requirements of this chapter.

(Ord. No. 07-6-12, § 5, 6-5-07)

Sec. 24-8.8. - Repair of motor vehicles in residential districts.

The repair of motor vehicles in the RC, RD, RM or the OR district shall be subject to the following restrictions:

(1)

Only minor repairs and maintenance may be performed which, for purposes of this section, are defined as the changing and replenishment of fluid levels, such as hydraulic fluid, windshield washer fluid and lubricating oil; the replacement of spark plugs and ignition points; the rotation of tires and replacement of drive belts and hydraulic lines.

(2)

All other repairs shall be confined to totally enclosed spaces and only accomplished on privately registered vehicles having current license plates, or vehicles designated by the state as qualifying for antique carriage designation.

(Ord. No. 07-6-12, § 5, 6-5-07)

Sec. 24-8.9. - Garage and yard sales.

Garage, yard, tag, patio and apartment sales are permitted in all districts. However, such sales shall be limited in residential districts to four (4) per calendar year, with a maximum duration of two (2) days per sale.

(Ord. No. 07-6-12, § 5, 6-5-07)

Sec. 24-8.10. - Placement of objects and vehicles on, in, or adjacent to road rights-of-way, road easements, and roadways; hazardous objects.

(1)

No signs, fences, walls, or other objects, including vehicles, may be placed either temporarily or permanently on or in any road rights-of-way, road easements, or roadways owned by the federal, state, or county government, except by a duly authorized governmental department or agency and/or except as permitted by federal, state, or county law, including Aiken County Code section 19-5. This provision does not prohibit the appropriate parking of vehicles in or on roadways where authorized, where not prohibited, and/or where such parking does not block any travel lane of the road.

(2)

No hazardous vehicles such as fuel-tanker trucks, trucks for the transport of propane gas or natural gas, chemical tankers, or other similar vehicles or objects containing hazardous and/or toxic materials may be placed or parked either temporarily or permanently in or on any such road rights-of-way, road easements, or roadways. In addition, no such hazardous vehicles or objects may be placed or parked temporarily or permanently in or on the adjacent areas within ten (10) feet of the outer edge of any such road rights-of-way or road easements.

(3)

There are two exceptions to the above provisions of this section in regard to vehicles. The first exception is in the event of mechanical vehicular breakdown or accident; in such limited cases the vehicles and their contents shall be removed as soon as possible from said road rights-of-way, road easements, roadways, and adjacent areas within ten (10) feet of the outer edge of said rights-of way or road easements. The second exception is for brief stops of vehicles for the purposes of delivery and/or pickup of materials where appropriate off-street parking or loading space on private property is not available.

(Ord. No. 07-6-12, § 5, 6-5-07)
