Zoning
R-1
Single-Family Residential District
To further the objectives set forth in the purpose statements and community development objectives in Article I of this chapter, the R-1 District is intended to provide for low to medium density single-family residential development while allowing for community and municipal facilities that are customarily found in residential districts. The requirements established for this district are to promote a safe and quiet nature for the residents and to discourage uses that would be detrimental to this intent, such as transient lodging in single-family dwellings.
