15.36.010 - Definitions.¶
Whenever used in this chapter, unless a different meaning appears from the context, the words and phrases set forth in this section shall have the following meanings:
A. "Automobile trailer," "trailer coach," or "trailer" means any vehicle or structure so designed and constructed in such manner as will permit occupancy thereof as sleeping quarters for one or more persons, or the conduct of any business or profession, occupation or trade (or use as a selling or advertising device), and so designed that it is or may be mounted on wheels and used as a conveyance on the highways or city streets, propelled or drawn by its own or other motive power, excepting a device used exclusively upon stationary rails or tracks. The definition herein expressed pertains whether or not such a trailer does or does not have attached thereto wheels, rims or tires.
B. "Cabin plot" means a section of ground not less than thirty feet by forty feet in area, upon which only one camp cottage or cabin is located.
C. "Person" shall be construed to include person, partnership, firm, company, corporation, tenant, owner, lessee, or licensee, their agents, heirs or assigns.
D. "Tourist camp" means any park, tourist park, tourist court, camp, court site, lot, parcel, or tract of land upon which one or more camp cottages or cabins are located and maintained for the accommodation of the transients by the day, week, or month, whether a charge is made or not.
E. "Trailer camp" means any park, recreational vehicle park, camp, site or lot where one or more spaces are rented, leased or held out for rent to owners or user of trailers or recreational vehicles which are occupied for temporary or seasonal use. Said camp includes all buildings, tents and structures intended for use of the camp. A trailer camp shall not include automobile or recreational vehicle sales lots on which unoccupied trailers are marked for purposes of inspection and sale.
F. "Unit" means a section of ground in a trailer camp of not less than eight hundred square feet of unoccupied space in an area designated as the location for only one automobile and one trailer.
G. "Recreational vehicle" means a motor home, travel trailer, truck camper, or camping trailer, with or without motor power, designed for human habitation for recreation or emergency occupancy or the conduct of any business, is eight feet or less in overall width and forty feet or less in overall length, or a bus conversion for human habitation.
H. "Mobile home" means a vehicle registered with the California Department of Motor Vehicles and designed and equipped for living purposes which is over eight feet in overall width and more than forty feet in overall length.
I. "Mobile home park" means any area or tract of land where two or more mobile home lots or spaces are rented or leased or held out for rent or lease to accommodate mobile homes used for dwelling purposes.
J. "Modular home" means a manufactured home which meets the current Uniform Building Code (UBC) adopted by the city; the same as a conventional onsite constructed dwelling. A modular home is not subject to the Federal Department of Housing and Urban Developments nationwide mobile home construction and safety standards code; and therefore, a modular home is not a mobile home. A modular home meeting the current UBC may be placed in any zone allowing single-family residential dwellings.
K. "Manufactured home" means a residential building, dwelling unit, or an individual dwelling room or combination of rooms thereof, or building component, assembly, or system manufactured in such a manner that all concealed parts or processes of manufacture cannot be inspected before installation at the building site without disassembly, damage, or destruction of the part which is either wholly manufactured or is in substantial part manufactured at an offsite location to be wholly or partially assembled on site in accordance with building standards published in the State Building Standards Code. "Manufactured home" does include a mobile home which was constructed after July 1, 1976, and was issued an insignia of approval by the U.S. Department of Housing and Urban Development.

15.36.020 - Establishment—Conditional use permit required—Application.¶
Trailer parks shall be established only by conditional use permit in appropriate zones as set forth in the "Land Use Zoning Ordinance of the City of Ione." In applying for a conditional use permit for the construction of a trailer park, the applicant shall provide the following:
A. The name and address of the applicant;
B. The location and legal description of the trailer park;
C. A complete plan of the proposed trailer park in conformity with all of the requirements for such as contained in all applicable ordinances;

(Ord. 97 §3(part), 1961)
15.36.030 - Alteration or enlargement—Conditional use permit required.¶
A. A trailer park shall be deemed to be enlarged or altered when additional structures or trailer sites or accommodations for additional trailer coaches are established in the trailer park or on adjacent land owned or operated by the same person.
B. A conditional use permit is required before alteration or enlargement of existing trailer parks is permitted. The information required by Section 15.36.020 shall also be required in connection with alteration or enlargement of existing trailer parks, but only for the portion of the trailer park to be affected directly by the proposed alteration or enlargement.
(Ord. 97 §3.01, 1961)
15.36.040 - Limitations on conditional use permit.¶
Conditional use permits authorized by the city council for trailer park developments shall be in force and effective for only six months unless specified for longer or shorter periods of time. If construction of the trailer park is not begun and continued during the period for which the conditional use permit is issued, then the permit shall become void.

15.36.050 - Parcel location review.¶

A fee of twenty-five dollars shall be charged to cover costs of public notice. The purpose of the hearing shall be to enable the planning commission to review the location of the proposed trailer park and determine propriety in relationship to the overall development patterns of the city, the objectives of the master plan, and adjacent land uses. All planning commission findings shall be subject to review and final determination of the city council. A parcel location review is not a substitute for the conditional use permit application requirement nor does it relieve the obligation to meet all the requirements of the chapter relative to conditional use permits.
