21.70.050 Purpose.

The purpose of this chapter is to establish minimum standards and requirements for the construction and operation of manufactured home developments and mobile home parks. It is the intent of this chapter to recognize the changing trends of manufactured or mobile home development and to provide regulations which allow a degree of flexibility in construction and design. Specific regulations are also necessary to address the unique design characteristics of such developments and to prevent adverse impacts of such developments on surrounding properties. It is also the intent of this chapter to provide for the continued safe operation of older existing mobile home parks. (Ord. 2433 § 1(Exh. C), 2002; Ord. 2020 § 23, 1994; Ord. 1781 § 9, 1990)

21.70.200 General provisions.

A. Location and Occupancy.

1. Manufactured homes are permitted on lots which are zoned for residential use, subject to the same development regulations as other forms of single-family housing.

2. Manufactured homes are permitted in mobile home parks or manufactured home developments, and mobile homes are only permitted in mobile home parks.

3. Recreational vehicles are not allowed as permanent year-round dwellings nor as replacement units in mobile home parks or manufactured home developments.

4. All proposed structures shall meet the requirements of the International Building Code as adopted by the city of Lynnwood or bear the appropriate seal of the Washington State Department of Labor and Industries.

B. Use and Density.

1. The uses within new developments, new mobile home parks and expansions of existing developments and parks under this chapter are limited to the uses permitted in the zone in which the development is proposed.

2. Existing mobile home parks are exempt from density limitations, except that any internal redevelopment or alteration shall not exceed the density limit for that park, as shown in Table 21.70.250.

3. Expansion of an existing park beyond current boundaries is allowed, provided the expanded areas comply with all development standards required for new manufactured home parks, including use and density.

21.70.300 Alteration or expansion of mobile home parks.

A. Alteration. Alteration is a change in the configuration, utilities, access or structures which does not increase the area of the mobile home park.

Alteration does not include repair or maintenance to existing facilities. Alteration shall include but not be limited to the following conditions:

1. The terms and conditions of any existing conditional use permit shall continue.

2. All structures within the area of the alteration shall meet the following setbacks:

a. No setback required from internal roads;

b. Five-foot setback from lot lines;

c. Ten-foot setback from any other mobile or manufactured home;

d. Five-foot setback from any other structure.

3. The mobile home park owner shall designate an internal, unobstructed road for general access and emergency access, at least 20 feet in width, or as may be approved as adequate in writing by the Lynnwood fire department.

4. All new structures shall meet the requirements of the Uniform Building Code as adopted by the city of Lynnwood or bear the appropriate seal of the Washington State Department of Labor and Industries issued after January 1, 1968.

B. Expansion. Expansion is a change in the area or configuration of the mobile home park which results in an increase in total area or in the number of units. Expansion of existing mobile home parks shall include but not be limited to the following conditions:

1. Expansions shall be coordinated extensions of the existing site;

2. Occupancy of any area added to an existing mobile home park shall be limited to manufactured homes;

3. All proposed structures within the area added to the mobile home park shall meet the setback requirements in subsection (A)(2) of this section;

4. The expanded area shall be served by an internal, unobstructed road for general access and emergency access, at least 20 feet in width, or as may be approved as adequate in writing by the Lynnwood fire department. (Ord. 2433 § 1(Exh. C), 2002; Ord. 2020 § 23, 1994; Ord. 1781 § 9, 1990)

21.70.400 Replacement of mobile or manufactured homes in existing mobile home parks.

Mobile or manufactured homes or other types of units which are removed from existing mobile home spaces may only be replaced with a mobile or manufactured home. Recreational vehicles are not allowed as replacement units. (Ord. 2433 § 1(Exh. C), 2002; Ord. 2020 § 23, 1994; Ord. 1781 § 9, 1990)

21.70.500 Development of new manufactured home parks.

Proposed manufactured home parks shall be reviewed under the provisions of LMC 1.35.300, Process III: administrative permits review process, and shall include but not be limited to the following requirements:

A. Manufactured home parks shall have a minimum site size of 3.0 acres;

B. The maximum permitted density is six units per net acre;

1. Ten-foot setback between the unit and internal access road;

2. Ten-foot setback between each unit, except as approved per subsection F of this section;

3. Six-foot setback between a unit and another accessory structure;

4. Twenty-foot front setback for units that front on a public right-of-way;

E. A 15-foot-wide planting strip shall be provided along the perimeter of the park, except as provided in subsection F of this section. The perimeter strip shall consist of:

1. Evergreen conifer trees with a minimum height of six feet and spaced a maximum of 15 feet on center;

2. A six-foot high fence which forms an effective barrier to sight; and

3. Evergreen plantings that will mature to a total ground cover within five years in the rest of the landscaped strip;
