New mobile home parks are subject to all of the land use, density, site requirements and development standards of the underlying zone with the following exceptions:

(1)    Size. A mobile home park shall be at least three acres in area.

A mobile home park may include either mobile or manufactured housing provided that the mobile homes meet the minimum livability and safety requirements set forth in the Redmond Building Code. A mobile home park may also include: an office for the use of a manager, a common laundry facility for use of the tenants, a common recreation facility for primary use of the tenants, a common storage area, or an on-site day care facility.

(3)    Separation. A minimum of 10 feet of separation shall be maintained between all units which shall include modular or site built additions, decks, porches or roof structures excluding decks, patios, or walkways less than 30 inches above grade. Exceptions may be made to allow carports constructed of non-flammable materials, in which case the minimum separation shall be five feet from that carport to the neighboring unit. Accessory structures shall maintain the following separations:

(a)    Ten feet to mobile homes on adjacent spaces;

(b)    Five feet to accessory structures of mobile homes on adjacent spaces;

(c)    Five feet to the mobile home or other accessory structures on the same space, except for a carport or garage which may be attached to the mobile home; this separation may be waived when accessory structures are constructed of non-flammable materials.

(4)    Coverage/Impervious Surface Area. A mobile home park shall be exempt from the structure coverage and impervious surface area requirements set forth in RCDG 20C.30.25-140, Site Requirements Chart.

(5)    Parking. Two spaces per unit shall be required. At least one of the spaces shall be off-street parking and shall be located on or adjacent to each mobile home pad.

(6)    Screening. A mobile home park shall have site screening compliant with Chapter 20D.80 RCDG, Landscaping, Natural Screening and Tree Preservation, and may include fencing, so that the mobile home park is visually separated from surrounding residential uses.

(7)    Access and Driveways.

(a)    Internal roads and sidewalks shall provide access to each mobile home space and shall be constructed in accordance with the adopted City of Redmond road standards for residential local access streets or private streets.

(b)    Private streets may be used provided that such streets do not directly connect two or more points of vehicular access to the park, provided that no roadway shall exceed 150 feet in length without providing a fire vehicle turnaround area, and provided that the roadway is not intended to accommodate required parking.

(c)    Driveways must be spaced to maximize the distance between one driveway and another and between driveways and road intersections. Driveways shall be aligned wherever possible with existing driveways on the opposite side of the street. Joint use of driveways is allowed.

(8)    Skirting. All mobile homes supported by piers shall be fully skirted.

(9)    Recreational Vehicles. No spaces or pads in a mobile home park may be used to accommodate recreational vehicles. A mobile home park may include a storage area for recreational vehicles owned by the residents of the park provided the storage area contains no utility hook-ups and recreational vehicles within the storage area are not used as living quarters. (Ord. 1901)

20C.30.65-050 Nonconforming Mobile Home Parks.

(1)    Standards. Mobile home parks established prior to the effective date of this code shall continue to be governed by all standards relating to density, setbacks, landscaping and off-street parking in effect at the time they were approved.

(2)    New Structures. The replacement of mobile homes in existing mobile home parks shall be governed by the site requirements in effect when the parks were approved. Where internal setbacks are not specified, the average of the prevailing setbacks on the pads to either side of the proposed new or replacement structure shall apply. New accessory structures must meet the setback requirements of conforming mobile parks unless the existing setbacks create an inability to meet these standards in which case the accessory structure shall be made of a fireproof material. Replacement mobile homes in nonconforming mobile home parks must be fully secured to the ground as required by the Redmond Building Code, fully skirted, and the structure must meet the minimum livability and safety requirements of the Redmond Building Code.

(3)    Recreational Vehicles. No spaces or pads in an existing mobile home park shall be used to accommodate recreational vehicles except where the spaces or pads were specifically for recreational vehicles at the time the park was established. All recreational vehicles shall be fully secured to the ground in the same manner as required for mobile homes under the current Building Code.

(4)    Enlargement. A nonconforming mobile home park may be enlarged provided the proposed enlargement meets the standards set forth for new mobile home parks in this section. (Ord. 1901)
