[Amended 1-19-2012]
A. 
General Provisions
1. 
In order to effectively implement the stated goals of the Calvert County Comprehensive Plan and Town Center Master Plans, if applicable, uses that do not conform to those goals shall be strictly regulated by the provisions of this Ordinance.
2. 
A Non-Conforming Use is defined as a use which lawfully existed prior to the adoption or amendment of this Ordinance, but, by virtue of the adoption or amendment of this Ordinance, is no longer a permitted use in the Zoning District within which it is located. For the purposes of this Section, the "date of nonconformity" shall be the date of the adoption or amendment of this Ordinance; the adoption or amendment of which rendered a use non-conforming.
3. 
See Section 8-1 of this Ordinance for requirements regarding non-conforming uses in the Critical Area.
B. 
Certificates of Non-Conformity
[Amended 1-19-2012]
1. 
Upon the request of a property owner, the Zoning Officer may issue a Certificate of Non-Conformity to establish the existence of a Non-Conforming Use, as defined herein. The Certificate shall include, among other information:
a. 
The date of non-conformity, which is the date of the adoption or amendment of this Ordinance; the adoption or amendment of which rendered a use nonconforming.
b. 
The Zoning Ordinance Section(s) which caused the previously legal conforming use to become a Non-Conforming Use, and the date on which the Section(s) were adopted or amended.
2. 
The Zoning Officer shall establish procedures and appropriate forms for processing requests for Certificates of Non-Conformity.
3. 
A request for a Certificate of Non-Conformity for a Non-Conforming Use shall include the following information:
a. 
Evidence, as described below, clearly demonstrating that the use has continuously existed without interruption from the date of non-conformity through the application date for the Certificate of Non-Conformity (except such lapses as permitted by Section 2-6.01.F herein). Such evidence may include, for example:
i. 
Photographs of the property (ground level, overhead or aerial photographs) that clearly depict the use and include the date on which the photographs were taken.
ii. 
A valid building, grading, or use and occupancy permit substantiating the date of non-conformity and the legal status of the use.
iii. 
Other records, including tax records, receipts, etc., which establish that the use existed on the property as of the date of non-conformity.
iv. 
A plat or site plan of the subject property, prepared and stamped by a Registered Surveyor, which clearly depicts the location of all buildings, structures, and the area used by the Non-Conforming Use.
C. 
Continuation of Lawfully Existing Uses
Any use lawfully existing at the time of the adoption or amendment of this Ordinance may continue to be used even though such use is no longer permitted in the Zoning District in which it is located. Non-Conforming Uses may continue even if ownership of the property changes.
D. 
Expansion of Non-Conforming Uses
1. 
The Board of Appeals may approve expansion of a Non-Conforming Use provided that such expansion is restricted to 50 percent of the square footage of the area occupied by the use at the time the use originally became nonconforming under this or any previous Zoning Ordinance (date of nonconformity). The intent of this Section is to limit the amount by which a Non-Conforming Use may be expanded as of the date the use was deemed nonconforming by any Ordinance, past or present.
2. 
For a Non-Conforming Use that does not involve a building or structure, the area of the lot utilized by such a use as of the date of non-conformity may be expanded by up to 50 percent if approved by the Board of Appeals.
3. 
The criteria to be applied by the Board of Appeals when reviewing a request for expansion of a Non-Conforming Use shall be the same as those contained in Section 11-1.02 for special exceptions.
4. 
A Certificate of Non-Conformity, as described in paragraph 'B' of this Section, shall be issued by the Zoning Officer prior to application to the Board of Appeals for expansion of a Non-Conforming Use.
[Amended 1-19-2012]
5. 
When expansion of a Non-Conforming Use is proposed, the entire site shall be brought into conformance with the requirements of this Ordinance and/or the applicable Town Center Zoning Ordinance to the maximum extent feasible, as determined by the Planning Commission or its designee.
6. 
The Zoning Officer may permit an existing non-conforming manufactured home to be replaced, expanded or altered if it is determined to be habitable in accordance with Section 75-10 C(1) - (5), Minimum Livability Code, of the Calvert County Code.
E. 
Replacement of Non-Conforming Uses
1. 
A Non-Conforming Use may, with approval of the Board of Appeals, be changed to another Non-Conforming Use which the Board of Appeals finds to be of the same or a more appropriate use or classification.
2. 
Whenever a non-conforming use has been changed to a more appropriate use such use shall not thereafter be changed to a less appropriate use or classification.
3. 
The criteria to be applied by the Board of Appeals when reviewing a request for replacement of a Non-Conforming Use shall be the same as those contained in Section 11-1.02 for special exceptions.
4. 
A Non-Conforming Use may be replaced with a conforming use without approval from the Board of Appeals.
5. 
When replacement of a Non-Conforming Use is proposed, the site shall be brought into conformance with all other requirements of this Ordinance and/or the applicable Town Center Zoning Ordinance to the maximum extent feasible, as determined by the Planning Commission or its designee.
F. 
Discontinuance of Non-Conforming Uses
A Non-Conforming Use which has been discontinued or abandoned for nine consecutive months or for 18 months during a three-year period shall not again be used for a Non-Conforming Use except that non-conforming seasonal uses shall be permitted to continue unless discontinued or abandoned for a period of 24 consecutive months.
G. 
When a Non-Conforming Use Becomes a Special Exception
If a change to the Zoning Ordinance results in an existing Non-Conforming Use being permitted as a special exception use, the use shall be considered a conforming use. The owner shall automatically have a special exception and shall not be required to obtain a special exception from the Board of Appeals to continue the use. However, expansion in area of use or building area requires the approval of the Board of Appeals. The criteria to be applied by the Board of Appeals when reviewing such a request shall be the same as those contained in Section 11-1.02 or special exceptions.

The use of non-conforming structures may continue even if ownership of the property changes.
D. 
Change in Use Causing a Lawfully Existing Structure or Site to No Longer Conform to the Zoning Ordinance
In order for the use of any structure or site to be changed from one use to another, the structure and site must conform to the provisions of this Ordinance and/or the applicable Town Center Zoning Ordinance.

E. 
Expansion of Non-Conforming Structures
1. 
The Zoning Officer may approve the extension of a building wall or retaining wall which lawfully existed prior to the adoption, revision or amendment of the Zoning Ordinance but which fails, by reason of such adoption, revision or amendment, to conform to the current setback requirements subject to the conditions specified below.

Nothing in these regulations shall prevent the restoration of a non-conforming structure destroyed by fire, wind storm, flood, explosion or act of public enemy or accident, or prevent the continuance of the use thereof as it existed at the time of such destruction, provided that a building permit application is properly submitted within one year after the occurrence. This provision does not apply if an owner of a property intentionally destroys a non-conforming structure.
2. 
A non-conforming structure which is taken in a negotiated settlement or condemnation proceedings shall be permitted to relocate only on the same lot or parcel, or on a contiguous lot or parcel which was in the same ownership at the inception of the condemnation proceedings, and provided the applicable lot area, setback and height requirements of the District in which such use is a principal permitted use can be met. Such relocation or construction as existed prior to its taking may be permitted provided a building permit application is properly submitted within six months of the settlement date of the condemnation proceedings.
