No building, structure, or land shall be used except for the purposes permitted in the zoning district as described in Article 18. All uses are subject to all other applicable sections of this chapter and other local, state, and federal laws, rules and regulations.

Use regulations by zoning district are provided in the following tables which are located at the end of this chapter:[1]

A use denoted in the use tables by the letter "P" is permitted in that zoning district "by right." For some particular uses within particular districts there are special criteria/conditions that apply, as articulated in Article 20, Standards for Specific Permitted Uses. Where these special criteria/conditions apply there is a reference in the right column of the table. Always check these special criteria/conditions to see if they are applicable.

A use denoted in the use tables by the letter "C" is permitted in that zoning district by conditional use. Authorization of conditional uses is subject to review and approval by the Planning Board as articulated in Article 21, Conditional Uses. For some conditional uses within specific districts there are additional standards and/or criteria that apply, beyond the base criteria applicable to all conditional uses. Where these additional standards and/or criteria apply there is a reference in the right column of the table. Always check these criteria/conditions to see if they are applicable.

A use denoted in the tables by the letter "E" is permitted in that zoning district by special exception. Authorization of special exceptions is subject to review and approval by the Zoning Board of Adjustment as articulated in Article 22, Special Exceptions. For some special exceptions within specific districts there are additional standards and/or criteria that apply, beyond the base criteria applicable to all special exceptions. Where these additional standards and/or criteria apply there is a reference in the right column of the table. Always check these special criteria/conditions to see if they are applicable.

A use denoted in the tables by a dashed line "–" is not permitted in that zoning district.

Accessory uses are generally not listed in the attached tables. Permitted uses, conditional uses, and special exceptions are referenced to zoning districts whereas accessory uses are related to other uses (i.e., principal uses). They are defined in Article 2, Definitions, and discussed in Article 23, Accessory Uses. Nonetheless, some accessory uses which are also keyed to certain zoning districts (such as home occupations) are listed in the table; all accessory uses included in the table are labeled as such.

A proposed use shall be classified as the narrowest, most specific listed use that matches the proposed use. (Example: a proposed antique shop would be classified as an "antique shop" rather than as "retail sales.")
