Storage Sheds and Outbuildings 

A storage shed shall be defined as any structure whose primary purpose shall be for storage of equipment or materials and which does not in any way, or at any time, serve as a Living Unit as that term is defined in the Summer Ridge CCR's. Any structure whose primary purpose is for storage shall be reviewed as a shed and shall not be considered as a room addition. 

Any storage shed or out-building, such as a playhouse, will be considered under the following criteria: 

• It must reasonably blend in with the house and reasonably maintain continuity of materials with the house; such as siding (width exposure), roof material (product and color) and construction details such as trim, pitch of roof and doors and windows. 

• The colors must reasonably match the current color of the body and trim of the house 

• Approval of such buildings will also be determined by the number of other buildings on the property in the vicinity of the requested building. 

• Metal buildings are not allowed. 

• Prefab/prepackaged resin material buildings will be considered based on continuity of material with the house as stated above, size to not exceed one hundred (100) square feet and may only be located in the rear yard with no visibility from street . 

• Sheds and other outbuildings may not exceed twelve (12) feet in height, one hundred and twenty (120) square feet in size and must be placed at least (x) feet from the property lines shown below. 

• Sheds and other outbuildings may have utilities including electricity, and telephone, provided utilities comply with all City of Sammamish permit requirements. Water and sewage utility will not be permitted. A detached shed or outbuilding must be located in the rear yard with no visibility from the street.

Please ensure all applicable responses are provided in the initial ACC request to avoid delays.
