HDO: Historic District Overlay Requirements for the City of Charlotte
The HDO: Historic District Overlay in the City of Charlotte requires property owners to obtain a Certificate of Appropriateness (COA) before performing any exterior alterations, new construction, or demolition within a designated district. This overlay district is designed to protect historically and architecturally significant areas by ensuring all work is congruous with the special character of the district's size, scale, and massing. Violations of HDO: Historic District Overlay regulations, including performing work without a valid COA, can result in civil penalties and are classified as a Class 1 misdemeanor under the City of Charlotte's enforcement standards.
Purpose and Applicability
The HDO: Historic District Overlay is established by the City of Charlotte to encourage the restoration, preservation, and rehabilitation of historically, architecturally, and archaeologically significant areas and structures. The primary intent is to control the use and development of lots in conjunction with underlying zoning to prevent the decline or destruction of the city's heritage [Section 14.2.A].
The HDO: Historic District Overlay is an "overlay" zoning district, meaning it supersedes the regulations of the underlying base zoning district specifically regarding the compatibility and appropriateness of exterior features. The City of Charlotte prohibits the application of the HDO: Historic District Overlay in combination with the HDO-S (Streetside Historic District Overlay), NCO (Neighborhood Character Overlay), or RIO (Residential Infill Overlay) [Section 14.2.B].
Certificate of Appropriateness (COA)
In the City of Charlotte, no portion of a parcel or building exterior within an HDO: Historic District Overlay may be erected, altered, restored, moved, or demolished until a Certificate of Appropriateness (COA) has been issued by the Historic District Commission (HDC) [Section 14.2.D.1].

Scope of Review
The City of Charlotte reviews "exterior features," which include:
- Architectural style and general design.
- The texture and kind of building materials.
- The size and scale of the building.
- Type and style of windows, doors, light fixtures, and signs.
- Significant landscape and natural features of the area [Section 14.2.E].
Minor Works and Maintenance
The Historic District Commission has the authority to delegate approval of "minor works" to professional staff. These are defined as alterations or removals that do not impair the integrity of the property or district and are not incongruous with its special character [Section 14.2.F].
Ordinary maintenance and emergency repairs do not require a COA, provided they do not involve a change in design, material, or outer appearance. In the event of an emergency, City of Charlotte staff may authorize immediate restoration to pre-disaster conditions, provided the work is documented photographically [Section 14.2.H].
Demolition and Removal
The City of Charlotte strictly regulates the removal of buildings within the HDO: Historic District Overlay. A COA is mandatory for any demolition. If the Historic District Commission determines a building has special significance, it may delay the demolition for up to 365 days to negotiate with the owner to find a means of preserving the structure [Section 14.2.J.2].
This delay may be reduced if the Historic District Commission finds that the owner would suffer extreme hardship or be deprived of all beneficial use of the property [Section 14.2.J.3].
Enforcement and Appeals
The Zoning Administrator is responsible for enforcing HDO: Historic District Overlay regulations. Violations include performing work without a COA, carrying out a project despite a COA denial, or performing work inconsistent with an approved COA [Section 14.2.N].
Appeals regarding HDO: Historic District Overlay decisions are taken to the Mecklenburg County Superior Court in the nature of certiorari [Section 14.2.M.1].
