14 Nonconformities

14.1.1. Purpose

Zoning regulations established by the adoption of this Ordinance or amendments to this Ordinance may cause properties and uses which were lawful prior to the adoption of certain regulation to not meet requirements after adoption of the regulations. The purpose of this section is to establish procedures and regulations for the use of those properties or structures which are in conflict with the requirements of this Ordinance. It is not the intent of this section to encourage the continuance of nonconformities that are out of character with the standards of the zoning district. This section allows certain nonconforming situations, only as described in this section, to continue as legal exceptions to this Ordinance.

14.1.2. Nonconformities Defined

A nonconformity shall be any use, lot, improvement, or structureClosed that, as a result of amendments to this Ordinance or a preexisting condition, does not meet the current standards of the Ordinance.

A. Nonconforming Use

A nonconforming use shall be any land use or type of residential use that was legally established but has become a prohibited use in the district in which it exists.

B. Nonconforming Lot

A nonconforming lot shall be any legally established parcelClosed that does not conform to the current area or dimensional requirements of the zoning district in which it is located.

C. Nonconforming Improvement or Structure

A nonconforming improvement or structureClosed shall be any legally established improvement, buildingClosed or structureClosed that fails to meet current Ordinance standards for setbackClosed, height, or similar factors.

14.1.3. Continuation of Nonconformities

A. Legal nonconformities may continue subject to the limitations of this Article. Continuation, reconstruction, alteration, and/or expansion of such nonconformities shall be subject to the provisions of this Article.

B. Uses Requiring a Major or Minor Special Use Permit

Buildings or uses which lawfully existed at the time of the initial effective date of this Ordinance which would require the issuance of a special use permit may continue as a conforming use without the special use permit. However, any future expansion of the buildingClosed or use in excess of 15% of the gross floor areaClosed or site size (measured from the size of the buildingClosed or use at the time of ordinance adoption) requires application for a special use permit in conformance with procedures found in this Ordinance.

14.1.5. Completion of Buildings and Improvements

A. Nonconformities Resulting from Adoption of This Ordinance or Other Governmental Action

Completion of buildings that become nonconforming as a result of passage of this Ordinance or another governmental action shall be allowed if an application for a building permitClosed sufficient to allow approval was submitted prior to passage of this Ordinance, and if the buildingClosed is subsequently completed in accordance with an approved building permitClosed within two years of initial issuance of the permit. In addition, completion of buildings for which buildingClosed permits were not applied for may be allowed under the Transitional provisions of this Ordinance. Completion of improvements other than buildings that become nonconforming as a result of passage of this Ordinance shall be governed by the Transitional provisions of this Ordinance.

B. Subsequent Nonconformities

Completion of buildings that are created by amendments to this Ordinance or another governmental action shall be allowed if a building permitClosed was issued prior to the amendment, if the permit remains continuously valid, and if the buildingClosed is completed within two years of initial issuance of the permit. Completion of buildings or improvements for which permits were not issued, but that are subject to site plansClosed or preliminary platsClosed that were approved prior to the Ordinance amendment, shall be governed by the provisions regarding continuous validity of site plansClosed and preliminary platsClosed found elsewhere in this Ordinance.

14.2.1. Limitations on Nonconforming Uses

Except as specified in paragraph 14.2.2, Changes to Nonconforming Uses (City Only), nonconforming uses shall be subject to the following restrictions, in addition to restrictions that may be imposed by other provisions of this ordinance or by conditions within a special use permit or other approved plan or permit:

A. Floor areaClosed shall not be enlarged, except for improvements that allow existing buildings to meet local health, sanitary, or safety code requirements or that are necessary to ensure safe living or occupancy conditions;

B. Residential densityClosed shall not be increased;

C. Lot coverage shall not be increased;

D. The nonconforming use shall not expand in degree, frequency, intensity, or impact of the activity;

E. The nonconforming use shall not be relocated to another portion of a lot, except as allowed in the City pursuant to provisions authorizing the issuance of special use permits for certain nonconforming uses, described below; and,

F. The nonconforming use shall not be changed to a different nonconforming use, except as allowed in the City pursuant to provisions authorizing the issuance of special use permits for certain nonconforming uses, described below.

14.2.2. Changes to Nonconforming Uses (City Only)

A. A single-familyClosed residential nonconforming use can be expanded one time during its existence through enlargement of the floor areaClosed of the buildingClosed associated with the nonconforming use by a maximum of 10% or 500 square feet, whichever is greater, and an associated increase in lot coverage, provided that such expansion complies with all developmentClosed standards of the established zoning district in which the nonconforming use is located at the time of expansion.

B. Nonconforming uses located on a boulevardClosed or major/minor thoroughfare may be changed to a different nonconforming use, or range of uses, or relocated on the same site, upon issuance of a minor special use permit pursuant to Sec. 3.9, Special Use Permit. The Board of Adjustment may limit the time period for which such a use permit is valid, if it determines such limitation is necessary or in the public interest. In order to issue such a permit, in addition to consideration of all criteria generally applicable to special uses, the Board of Adjustment shall find that:

1. The proposed new nonconforming use, if a new nonconforming use is proposed, is more compatible with the developmentClosed pattern of the surrounding area than the previous nonconforming use; and

2. Mitigation measures included as specific conditions in the permit, if necessary, are adequate to provide protection for nearby properties; and,

3. The proposed use, range of uses, or relocation of uses reduces the impacts on the surrounding area in comparison with the established nonconformity. In making this determination, the Board of Adjustment may consider factors such as:

a. Whether the proposed new nonconforming use is considered less intense than the previous nonconforming use considering the uses permitted in each zoning district and the hierarchy of zoning districts established in paragraph 4.1.1, Establishment of Districts, with the districts listed in order from least intense to most intense;

b. Whether the proposed new nonconforming use can be expected to generate less traffic, particularly peak hour traffic, than the previous nonconforming use; and,

c. Whether the proposed new use can be expected to result in a decrease in parking demand from the previous nonconforming use.

14.2.3. Abandonment

A nonconforming use can be changed at any time to a use that conforms to a use allowed by the zoning district. A nonconforming use shall not be re-established if it is:

A. Converted to a conforming use;

B. A use that utilizes a structureClosed and is abandoned for a period of at least six consecutive months, as evidenced by termination of utilities, declaration of inhabitability, or other action that the Planning Director or designee deems an indication of abandonment;

C. A use that is conducted outside of a structureClosed and is abandoned for a period of at least 30 days as evidenced by removal of equipment or other action that the Planning Director or designee deems an indication of abandonment; or,

D. In the City, changed to a different non-conforming use through the issuance of a minor special use permit.

14.2.4. Damage/Destruction

A. A nonconforming use other than a single-familyClosed use that is contained in a structureClosed that is damaged or partially destroyed can be reestablished if the damage is less than 50% of the appraised tax value, a completed building permitClosed is issued within 12 months of damage or partial destruction, and construction is completed within 12 months of issuance of the permit.

B. A single-familyClosed nonconforming use can be reestablished in any event.

C. No new structureClosed may be constructed to be used as an accessory structureClosed to a nonconforming use.

D. In Design Districts, a nonconforming use that is contained in a structureClosed that is damaged or destroyed can be reestablished by right if a completed building permitClosed is issued within 12 months of damage or destruction, and construction is completed within 12 months of issuance of the permit.

14.2.5. Home Occupations

14.2.6. Single-Family Use Exemption

A. Single-familyClosed uses that were existing as of January 1, 2006, shall be exempt from the limitations of this section.

B. Educational facility uses that were existing as of January 1, 2024, shall be exempt from the limitations of this section.

C. Existing educational facility uses which were approved through the special use permit process, pursuant to Sec. 3.9, Special Use Permit, shall allow expansions of no more than 20% to be approved administratively. Any expansion must still adhere to any conditions imposed by the associated Special UseClosed Permit.

14.3.1. General Standards

A. The creation of a lot with a width or area smaller than allowed by existing zoning requirements is prohibited, except as follows:

1. By governmental action, such as a roadClosed widening or an officially adopted housing program;

2. Where such lot is comprised of one or more legal nonconforming lots that are being enlarged to create a lot that more closely meets Ordinance standards;

3. Where the creation of such a lot lessens the extent of a nonconforming use and/or structureClosed condition;

4. For the purposes of setting land aside as permanent open spaceClosed with no developmentClosed rights, provided that the resulting lots satisfy the applicable dimensional requirements for an open spaceClosed lot pursuant to Sec. 7.2, Open Space; or

5. A varianceClosed is approved pursuant to Sec. 3.14, VarianceClosed.

B. Where governmental action has reduced the size of a lot, construction, reconstruction, and additions to structures on the lot shall be considered under the standards for nonconforming lots set forth in this subsection.

14.3.2. Single-Family and Two-Family Residential Lots

A. Any legally established lot of recordClosed not located within a Special Flood Hazard Area that has a minimum width of 30 feet created prior to the effective date of this Ordinance that is located on a street that is accepted and maintained by NCDOT or the City (or such other form of access as is permitted pursuant to paragraph 12.2.2, Other Forms of Access) may be developedClosed with a single-familyClosed or two-familyClosed residence subject to all other applicable ordinance requirements; and the availability of water and wastewater treatment systems, so long as such use is a permitted use in the district in which the property is located.

B. Lots that do not meet the requirements of paragraph A, above, may be developedClosed following approval by the Board of Adjustment as a minor special use in accordance with Sec. 3.9, Special Use Permit, and the Board of Adjustment’s making one of the additional following findings:

1. The general area around the subject lot is developedClosed and the size of the lot to be developedClosed is reasonably consistent with the general pattern of surrounding developmentClosed; or

2. The general area around the subject lot is developedClosed and the buildingClosed to be constructed will not substantially impact surrounding developmentClosed in a negative manner; or

3. It would be unreasonable or cause undue economic hardship to not allow developmentClosed of the subject lot. Factors to be considered include, but are not limited to:

a. Ownership history;

b. Prior developmentClosed approvals regarding the subject lot or surrounding lots;

c. Economic investments; and

d. The purposes to be served by requiring compliance with lot size requirements.

C. Side yardClosed requirements for single-familyClosed or two-familyClosed residential developmentClosed on nonconforming lots that do not meet lot widthClosed requirements shall be reduced as follows:

1. In the Rural Tier, the sum of the width of the two side yardsClosed of a nonconforming lot of recordClosed shall be at least 25% of the lot widthClosed. The minimum single side yardClosed of a nonconforming lot of recordClosed shall be 12% of the lot widthClosed. In addition to these requirements, the following minimums apply: if the nonconforming lot of recordClosed exceeds a width of 55 feet, then each side yardClosed shall be a minimum of eight feet wide. If the nonconforming lot of recordClosed is 55 feet wide or less, each side yardClosed shall be a minimum of six feet wide.

2. In all other tiers, as applicable, no total side yardClosed is required and each individual side yardClosed shall be at least 80% of the required side yardClosed for the district in which the lot is located.

14.3.3. Lots Other than Single-Family or Two-Family Lots

14.4.1. Nonconforming Buildings or Structures

A. Special Flood Hazard Areas or Future Conditions Flood Hazard Areas

1. Reconstruction of buildings, including single-familyClosed homes, that are located in Special Flood Hazard Areas or Future Conditions FloodClosed Hazard Areas, shall not be permitted if the structureClosed has experienced substantial damageClosed or repetitive lossClosed.

2. Any construction or developmentClosed in such areas shall be subject to Sec. 8.4, Floodplain and Flood Damage Protection Standards, in addition to the requirements of this section.

B. General

1. No enlargement or reconstruction shall have the effect of increasing the degree or extent of a nonconforming feature.

a. Additions that are proposed between the minimum yardClosed requirement and the existing building lineClosed, or are consistent with the existing height, shall not be considered to increase the degree or extent of the nonconformity.

b. An addition shall be considered to increase the nonconformity if it extends further into required yardsClosed than the existing encroachmentClosed.

2. No enlargement or reconstruction shall create new nonconformities or encroachmentsClosed, unless a varianceClosed is approved pursuant to Sec. 3.14, VarianceClosed.

C. Approval

Additions or improvements to, or reconstruction of, nonconforming buildings and structures shall require approval of a minor special use permit pursuant to Sec. 3.9, Special Use Permit, unless exempted as follows:

1. Improvements, or additions of any size, that:

a. Comply with all current ordinance requirements; or

b. Bring the structureClosed into greater conformity with current ordinance requirements.

2. Projects that allow existing buildings to meet local health, sanitary, or safety code requirements or that are necessary to ensure safe living or occupancy conditions;

3. Projects that require a certificate of appropriateness pursuant to Sec. 3.17, Certificate of Appropriateness;

4. Additions, with a maximum increase in square footage of 100%, that are proposed between the minimum yardClosed requirement and the existing buildingClosed encroachmentClosed line;

5. Reconstruction of the nonconforming structureClosed that is within the original buildingClosed footprint. Proposed additional square footage shall meet the parameters of paragraphs c or d above, as applicable, to be exempt from the requirement of a minor special use permit;

6. Reconstruction or enlargement of, or improvements to a nonconforming structureClosed that is part of a housing program initiated by or supervised by the City, County, or an entity created by the City, County, or State of North Carolina, as long as the degree or extent of the nonconforming feature is not increased.

D. Time-Period Limitations for Reconstruction of Nonconforming Structures

1. Single-familyClosed or duplex structures, and associated accessory structures, can be re-built within the original buildingClosed footprints as long as a certificate of complianceClosed for the new structureClosed is issued within 36 months of the date of demolition or destruction of the original structureClosed. Otherwise, current ordinance requirements shall be met. The Planning Director can issue an extension for up to 12 months, as long as documentation is provided that demonstrates due diligence has been made to re-build the structureClosed.

2. MultifamilyClosed and non-residential structures can be re-built within the original footprints as long as a certificate of complianceClosed for the new buildingClosed is issued within 36 months of the date of destruction or demolition. Otherwise, current ordinance requirements shall be met.

14.4.2. Improvements to Nonconforming Land Improvements that are not Structures

14.4.3. Construction on, Redevelopment of, and other Improvements to Nonconforming Development Projects

DevelopmentClosed projects, such as those approved in accordance with a site planClosed or preliminary platClosed, may no longer conform to Ordinance requirements in all areas, such as impervious area, stormwaterClosed improvements, flood elevations, location of constructed areas, vegetated areas, or buffers. Such projects shall be considered nonconforming projects. Additions to, enlargement of, redevelopment of, or other construction on such projects shall be subject to the following provisions:

A. If the construction affects discrete portions of the developmentClosed project those portions can be considered without regard to compliance of the entire project with the Ordinance. In such case, current Ordinance requirements shall be applied to the improvements for which approval is requested to the maximum degree reasonable in light of the fact that the developmentClosed project as a whole does not comply with current requirements; and

B. Redevelopment of a developmentClosed project, defined as construction that exceeds 50% of the appraised tax value of the project, shall be subject to all current Ordinance requirements.
