§ 6.3. RM-18 Multi-Family District.

6.3.1.

Purpose. It is the intent and purpose of the RM-18 Multi-Family District to provide for and protect high-density multi-family development and accessory uses normally necessary and compatible with such use. The regulations which apply within this district are designed to encourage the formation and continuance of a stable, healthy environment for several different types of multi-family dwellings, and to discourage unwanted encroachment of commercial, industrial, or other uses capable of adversely affecting the residential character of the district.

•

Accessory use in compliance with the provisions of section 14.10.

•

Customary home occupation established under the provisions of section 14.9.

•

Garden or other noncommercial horticulture or agriculture (not including the keeping of poultry, livestock, or kennels).

•

Multi-family dwellings (attached).

•

Publicly-owned building, facility, or land.

•

Single-family dwellings (detached).

•
