Key Regulations and Restrictions

• Accessory Structures: Structures must be subordinate to the primary residence in size and appearance. In residential districts like RS-7.5, accessory structures are limited in size based on the lot area; for a 7,500-square-foot lot (as it falls between the 6,000 and 8,000 square foot tiers), the maximum floor area for accessory structures in rear yards is 560 square feet [Section 18.200.030].
• Fencing: Fences and walls located along a front property line or within a front setback are limited to a maximum height of three feet. On properties where residential uses are allowed, maximum fence heights are generally six feet, with specific exceptions for increased height in side or rear yards if constructed with lattice [Section 18.150.040].
• Parking: For existing single-family homes, two parking spaces are required (at least one covered), with none allowed within the required front yard setback. New homes with four bedrooms or less require at least two enclosed garage spaces [Section 18.160.040].
• Transitional Requirements: When development occurs on lots adjacent to other residential zones, additional setbacks or screening may be required to ensure compatibility [Section 18.150.180].
