Zoning
R-6
Single Family Residential District
The purpose of the single-family residential district regulations is to allow a designated area for single-family residential district development designed to provide as much compatibility as possible with nearby zoning. Intense agricultural uses which create strong or obnoxious odors, or which might disturb adjacent or nearby residential areas with noise or vibration, are not appropriate for the single-family residential zoning districts. The City of Oakley Residential Design Guidelines (see Appendix A of this chapter) should also be referred to as they contain additional information regarding mandatory and suggested guidelines for residentially zoned areas.
