The ordinance codified in this chapter shall be known as "the house and lot numbering ordinance for Lassen County."
(Ord. 377 § 1, 1966)
"House or lot number"
means the street or road address assigned to a parcel of real property for identification purposes and shall be exclusive of all other numbers such as subdivision lot numbers, etc.
(Ord. 377 § 2, 1966)
The planning and building services department shall have sole authority for assignment of house and/or lot numbers in accordance with this chapter. It shall be the duty of the building division to require the assignment of numbers as required by this chapter prior to the issuance of a permit on any new construction completed after the effective date of subindex maps for the area in which the construction is taking place.
(Ord. 377 § 1, 1966; Ord. 446 § 2, 1980; Ord. 2026-02, 3/24/2026)
The planning commission shall function as an appeals board to review disputes over house and/or lot number assignments and the recommendation of this commission shall be final.
(Ord. 377 § 2, 1966)
The basis for the uniform property numbering system shall be universal Transverse Mercator Grid, Zone 10, as shown on the U.S. Geological Survey Quadrangles for Lassen County, in metric units. These metric grid lines will control the numbering scheme. House numbers shall be assigned along each line in increasing magnitude in easterly and northerly directions in accordance with the distance from the point of origin. One thousand six hundred and nine numbers shall be assigned to each mile along the grid lines which, for the purposes of this section, shall be deemed equivalent to one thousand numbers per kilometer. Lassen County's number range is approximately 4,399,000 on the south to 4,563,000 on the north and 639,000 on the west to 758,000 on the east. For the purposes of determining the proper number for a particular location, the number assigned shall be proportioned to the distance of the location from its adjoining index lines and shall be in sequence with numbers established on adjacent properties. On all streets and roads the numbering will be even on the south and east and odd on the west and north. To insure a six digit number (and prevent future confusion) the four million digit will be eliminated from the south-north number range.
(Ord. 377 § 1, 1966; Ord. 446 § 3, 1980)
A. 
Master Grid Index Map. A master grid index map or maps shall be adopted by the board of supervisors showing the base lines and index lines. The map or maps shall become effective on adoption by resolution of the board.
B. 
Subindex Grid Maps. Subindex maps shall be prepared by the county surveyor showing details of precisely numbered areas. These maps shall then be maintained as necessary by the county surveyor to designate the numbers and location of numbers assigned to particular buildings or lands. These maps shall become effective on completion or revision by the county surveyor.
(Ord. 446 § 4, 1980; Ord. 2026-02, 3/24/2026)
All streets and roads, whether public or private, whether dedicated or not, and county highways (all hereinafter referred to as "roads") shall be named pursuant to this section and such roads shall be known by the name assigned. No road shall be deemed officially named unless it has been approved by the board of supervisors by order duly made and reflected in its minutes or by resolution. All official names existing on the effective date of this chapter shall remain the same until changed pursuant to this section. The public works department shall administer this section and shall have administrative responsibility for all road naming in the county. The public works department shall maintain a list of all road names so approved or in existence and shall certify to the board of supervisors that no name submitted for approval duplicates or so closely approximates an existing name as to cause confusion. The public works department shall initiate a program to officially name all existing roads for which no name has been officially named. Where unofficial road names exist or are commonly used on the effective date of this chapter they may continue to be used and the public works department shall initiate their official naming, provided that they are not in conflict with existing official names. Where a public hearing is required to officially name, or change the name of a road, the public works department shall initiate such a hearing before the board of supervisors. No subdivision or division of land shall be approved until all the roads therein or contiguous thereto have been officially named by the board of supervisors after one name for its entire length or where a road changes direction by ninety degrees or greater a different name may be adopted for such changed direction to facilitate its numbering.
(Ord. 446 § 5, 1980)
After the effective date of any subindex map, or revision thereof, the county surveyor will give either verbal notice or written notice to the owner or occupant of buildings or land which are assigned, or reassigned numbers pursuant to this chapter, which notice shall contain the new number assigned. Written notice may be given by posting, personal delivery or first class mail. Notice of assigned or reassigned numbers shall be given to the building division which shall require display of the number prior to inspection of any issued permit. Within thirty days after the county surveyor has given notice, the owner or occupant of the building or property shall cause the number to be displayed horizontally on the building or land in such manner as to be visible from the street or road on which the building or land fronts and shall remove or obscure from public view any old or previous numbers not in accordance with this chapter; provided, however, that where buildings are removed a considerable distance from any public street or road such number shall be displayed at the entrance of any roadway or driveway leading to such building; provided further, that in rural areas where rural free delivery of mail is provided, the number may be displayed horizontally upon receptacles designed for the delivery of mail where the receptacle is in the proximity of the roadway or driveway leading to the building. Numbers shall be maintained in a neat and orderly manner so as to remain readable. Numbers displayed shall be a minimum height of four inches, be reflective, shall not exceed a maximum height of one foot unless approved by the board of supervisors and shall be of a contrasting color from the basic background.
(Ord. 446 § 6, 1980; Ord. 2026-02, 3/24/2026)
Any preparation of numbering plans in advance of improvements on lots or any changes in existing lot numbers which involve two or more lots shall be accomplished in cooperation with other county departments, incorporated cities, utility companies and districts, fire departments and districts, and with the U.S. Post Offices affected.
(Ord. 377 § 1, 1966; Ord. 446 § 8, 1980)
Any person, either owner or occupant, firm, partnership, copartnership, corporation, whether as principal, agent or employee, failing or refusing to display an assigned number or displaying or permitting to be displayed a number not assigned, or removing or failing to maintain an assigned number shall be guilty of an infraction punishable by a fine not exceeding fifty dollars for a first violation, a fine not exceeding one hundred dollars for a second violation within one year and a fine not exceeding two hundred fifty dollars for each additional violation within one year. Each day of a violation of this chapter shall constitute an additional and separate offense.
(Ord. 446 § 9, 1980)
This chapter may be amended in part or in whole through action initiated by the planning commission or the board of supervisors and such amendment shall be preceded by advertisement in local newspaper at least ten days prior to date of at least one public hearing which will be conducted by the board of supervisors.
