BACKGROUND: The City's current zoning regulations for residential properties permit homeowners to build attached or detached secondary structures, such as garages, workshops, and home gyms, that can occupy up to 60% of their rear yard. While these regulations are designed to provide flexibility for property owners, recent development activities have raised concerns regarding the size, scale, and visual impact of these structures within established residential neighborhoods. Two recent examples, one on West Texas Street and another on Lakeview Drive near West Kimball Road, have resulted in the construction of significant secondary buildings that alarmed adjacent neighbors, nearby residents, and members of the Planning and Zoning Commission. These cases highlighted some unintended consequences of the current regulations, including effects on neighborhood character, privacy, and overall compatibility. In response to these concerns, the Planning and Zoning Commission has initiated a review of the City's secondary structure regulations. The primary objective of this review is to evaluate and refine standards related to: - The allowable number of secondary structures per lot, - The appropriate locations for such structures on residential properties, and - Revisions to size and height limitations tailored to properties based on the lot's size. This in-depth review was conducted through a series of six workshops held by the Planning and Zoning Commission. During these sessions, members examined current regulations, compared community standards, and collected public input. 360475 AM25-05.RCPH - Secondary Structures (1) 1 Secondary Structures The proposed amendments resulting from this process are designed to enhance the balance between homeowner flexibility and neighborhood compatibility. They aim to ensure that secondary structures suitably complement the scale and character of residential areas.
