This section shall not apply within mobile home parks or state licensed farm labor housing facilities.

Any manufactured or mobile home in place and not legally established prior to May 11, 1989 may be legalized with the issuance of all applicable permits from the Lassen County department of community development and health department provided the manufactured or mobile home has not been moved from its precise location on the property.

This subsection shall only apply to manufactured or mobile homes which could have legally been established, by right, within the zoning district it was placed, at the time of placement.

In the case of lots less than sixty feet in frontage width, one additional off-street parking space shall be provided for every two spaces normally required for the proposed use of the lot.

In any case where a building line or minimum setback line has been established (e.g., by parcel map or subdivision), the required yards shall not be less than the distance specified for such building line or setback and in no case shall the provisions of this title be construed as permitting any structures to exceed beyond such building line or setback.

Front yard: Minimum required, twenty feet; provided, that where four or more lots in a block have been improved with buildings, prior to the effective date of this section, the minimum front yard shall be the average of the improved lots if less than the required twenty feet, but not less than fifteen feet, except where combined with a B district.

Side yard: Minimum required, five feet on interior lots. The street side yard on corner lots shall be not less than ten feet, except where combined with a B district.

Natural or earth-tone colors shall apply;

Not more than two access points may be allowed on any street;

Minimum building setbacks shall be as applied to any main building in the zoning district within which the mini-storage warehouse is located, but shall be not less than the following:

Design review, pursuant to Chapter 18.118 of this title, shall be required.

In the event that any application for change of district boundaries initiated pursuant to Chapter 18.124 of this title, would result in the removal of the subject territory from an agricultural zone to a non-agricultural zone with a minimum parcel size of less than twenty acres, the construction of perimeter fencing will be required of the property owner as a condition of approval of such rezoning. The fence shall either enclose the perimeter of the territory to be rezoned or constitute the linear equivalent thereof along the boundary of the adjacent agricultural zone, with the permission of affected property owners, at the applicant's option and with the approval of the planning department.

For the purpose of this section the following definitions will govern:

The applicant will be required to install cattle guards where project access roads cross boundaries between agricultural zoning districts and nonagricultural zoning districts when the perimeter of the nonagricultural district has been completely fenced. Construction shall conform to the Forest Service specifications for cattleguards.

The board of supervisors may consider appeals to the requirements for fencing in subsections (b)(2) and (c) of this section in the event the applicant is joined in such appeal by owners of two-thirds of property within agricultural zones within a two-mile radius of subject area, but not less than fifty percent in number of all landowners.

This chapter shall be inapplicable in the event that a perimeter fence, with all required cattleguards, exists around the entire perimeter of the nonagricultural zoning district in which the proposed development is to occur, including all adjacent nonagricultural zoned areas.

Wherever the fencing requirements herein apply, the planning commission or board of supervisors may impose additional perimeter fencing standards designed to keep dogs and other pets from entering adjacent agricultural lands. Such fencing may include wire mesh fencing such as page wire or field fencing, provided that the mesh fencing does not exceed a height of forty-eight inches, and provided that such mesh fencing has been reviewed under the provisions of the California Environmental Quality Act.

Use Permit. Upon securing a Class I use permit the following may be allowed, provided that the use shall not, as determined by the planning commission, adversely affect the residential character of the neighborhood:

"Hemp" or "industrial hemp" shall only be allowed by right in districts that are not identified in subsection (2) below;

"Hemp" or "industrial hemp" shall not be allowed in the "R-1" Single Family Residential District, "R-2" Limited Multiple-Family Residential District, "R-3" Multiple-Family Residential District, "P.U.D." Planned Unit Development, "P-C" Planned Community District, "R-S" Resort District, "O-C-B" Public Campground/Boating/Beach District, "O-H" Historical Site District, "O-D" Primitive Area, "O-S" Open Space District, "T-P-Z" Timber Production Zone District, "F-R" Forest Recreation District, "A-F" Agricultural Forest District, "H-R" Hydroelectric District, or the "Y-C" Airport Commercial District.

"Hemp" or "industrial hemp" shall only be cultivated on parcels at least nineteen acres in size;

Any cultivation of "hemp" or "industrial hemp" must be at least one hundred fifty yards from any and all residences, existing schools, school bus stops, licensed day care providers, churches, or public parks that are under separate ownership from that of the parcel or parcels on which the "hemp" or "industrial hemp" is cultivated.

"Hemp" or "industrial" hemp may be cultivated both indoors and outdoors subject to the requirements of this section and any other applicable county, state, or federal regulations.

"Indoor" or "indoors" means that the structure within which "hemp" or "industrial hemp" is being cultivated, must be either a private residence or an accessory structure within the meaning of those definitions found in this section. All cultivation which does not specifically meet the definition of "indoor" or "indoors" is considered "outdoor" or "outdoors." The cultivation of "hemp" or "industrial hemp" which occurs in a greenhouse or hoop house is considered "outdoor" or "outdoors" cultivation for purposes of this title.

"Outdoor" or "outdoors" means any cultivation location that does not specifically meet the definition of "indoor" or "indoors" or is otherwise specifically defined as "outdoor" or "outdoors."

"Private residence" means a lawfully established structure, suitable for human occupancy as required by Sections 17922 and 17958 of the California Health and Safety Code. A recreational vehicle does not constitute a lawfully established structure for purposes of this title.

"Accessory structure" means a fully enclosed and secure structure that complies with the California Building Standards Code, that has a complete roof enclosure supported by connecting walls extending from the ground to the roof, and a foundation, slab, or equivalent base to which the floor is securely attached. The structure must be secure against unauthorized entry, accessible only through one or more lockable doors, and constructed of solid materials that cannot easily be broken through, such as two-inch by four-inch or thicker studs overlain with three-eighths-inch or thicker plywood or equivalent materials. An accessory structure is a structure that is secondary or incidental to a private residence. A structure cannot be an accessory structure if there is not a private residence on the premises. A greenhouse or hoop house is not an accessory structure for purposes of this title and all cultivation within a greenhouse or hoop house is to be deemed "outdoors".

Any product not meeting the above referenced requirements, required for the cultivation of "hemp" or "industrial hemp," shall instead be considered "cannabis" if it meets the definition of such as provided for in Section 19.030 of this code.
