(2) Development Conditions – Residential/Commercial Zones. 1. The front, rear and side yard setbacks for structures in these zones are not intended to be applied to each individual building when there are multiple buildings on a site. Rather, they are meant to be used to establish the minimum dimensional requirements for the perimeter of the development.
2. Setbacks are applicable to the primary structure and attached accessory structures.
3. Height may be increased to 55 feet for hotels/motels and 40 feet for bed and breakfast accommodations, boarding houses, residential units over retail/office/personal service uses in the MB-I zone. Heights may be increased to 40 feet for multifamily, and mixed use in the TN zone and to 55 feet for multifamily, townhouse, hotel/motels, and mixed use when the TN zone is located within 200 feet of SR 532. An additional 10 feet may be allowed for multifamily, townhouse, and hotel/motels when the TN zone is located within 200 feet of SR 532 if the structure includes a pitched roof and no additional floors are added.
4. Rear setbacks of 15 feet are required for residential uses. Setbacks may be reduced to five feet when property is served by an alley.
5. Maximum density in the TN zone is calculated based on the total number of dwelling units of all types per gross acre. The density for each housing type within a project is determined by the minimum lot size.
6. Side setback for commercial is zero.
7. Side setback for attached townhouse units and multifamily is zero for interior units and 10 feet for end units. Side setback for utilities and public facilities is 20 feet.
8. For automobile service stations the cross-section areas of service station canopy supports where they meet the ground shall be measured as coverage for the purposes of determining maximum lot coverage, and also shall be used for measurement of setback requirements.
9. Height may be increased to 55 feet when a minimum of 50 percent of the required parking is provided on the ground floor or when the structure is at least LEED silver certified except where the MB-II zone directly abuts a residential zone and the increased height would obstruct the view corridor of the existing homes.
10. Density may be increased to 60 du/acre for mixed use developments when 100 percent of the required residential parking is provided on the ground floor and the building is at least LEED silver certified.
11. General commercial – mixed use overlay zone shall comply with the specific standards of Chapter 17.79 SMC, Mixed Use Overlay.
12. Density shall be determined by the development standards required for the specific property, including, but not limited to: height, parking, landscaping, lot coverage, recreational and open space, and stormwater.
13. Maximum of four stories. The building shall have pitched roof or parapet roof design and comply with the architectural elements of Chapter 17.112 SMC, Architectural Design Standards. (Ord. 1492 § 3 (Exh. C), 2021; Ord. 1449 § 5, 2017; Ord. 1418 § 12, 2016; Ord. 1398 § 18, 2015; Ord. 1333 §§ 6 – 9 (Exh. C), 2012; Ord. 1332 § 7 (Exh. C), 2012; Ord. 1294 § 18, 2011).
