Current through Register Vol. 50, No. 9, September 20, 2024

A. The permanent parcel ownership map and parcel numbering system, as herein described, shall be used to identify all properties within the parish. It is designed to provide instant location of each parcel geographically within the parish, as well as within each ownership map sheet. The numbering system shall be incorporated into the parish's assessment records and shall be used to facilitate computerization of all parcels inventoried within the parish.

B. The parcel numbering system will consist of three basic parts: the map number, the block number, and the centroid number. These three basic parts shall form the unique Parcel Identification Number (PIN) to be assigned to every separate land parcel within the parish.

C. An example derivation of a Parcel Identification Number (PIN) for a specified property parcel is as follows:

1. hypothetical grid coordinates of a particular parcel centroid, taken from the Louisiana State Plane Coordinate System (North or South Zone) would be:

"X" (easting) coordinate = 3,702,147

"Y" (northing) coordinate = 540,316

2. the digits in each coordinate value are paired together by taking each digit separately from the east-coordinate and matching it with the corresponding digit of the north-coordinate:

30 7504 20 1341 76

3. forming the above seven pairs of digits into adjacent groupings, the following subtitles may be applied:

30

7504

20

1341

76

Redundant Numbers

Map Number

Block Number

Centroid Number

Redundant Numbers

4. the Louisiana Standard "Parcel Identification Number" (PIN) is then obtained by recording the middle three sets of numbers (middle 10 digits), which is written as follows:

7504 20 1341

5. based upon the 1,000 foot square map block designation previously developed, the block number and associated respective centroid numbers would place the PIN centroid of any parcel within a 10 foot square of the actual geometric centroid for any map scale in use.

D. Splits. Once the final parcel map has been completed and permanent parcel numbers have been established for each parcel, the map shall be considered to be part of the ongoing maintenance. Any split-off shall be assigned a new PIN for both the original and split-off portion based upon the revised geometric centroid of each new parcel resulting from the split.

E. Duplicate Centroids. In remote cases, identical parcel centroid numbers may be mathematically derived from contiguous parcels having uniquely peculiar geometric characteristics, such as a smaller tract centered within or otherwise partially surrounded by a larger tract. In such cases, the derived PIN shall be assigned to the smaller interior tract, and a new PIN shall be generated at any appropriate location within the surrounding larger tract in order to uniquely identify each contiguous parcel.

F. Condominiums. The tract of land or lot on which a condominium complex or similar development is located should be assigned a whole number as a permanent parcel identification number. Each condominium unit within the complex should be assigned a decimal number to identify each unit. As an example, a tract of land containing condominium units is assigned PIN 7504 20 1341. One condominium unit located on this tract should be assigned the number 7504 20 1341.01, a second 7504 20 1341.02, and so on through the last unit in the complex.

G. Leasehold Improvements. Buildings or improvements located on land that is under a documented lease, as provided by parish, and requiring separate appraisals and assessments should have a parcel identification number assigned to them. The land being leased for the improvements should be indicated on the map sheet with the use of a dashed line to encompass the leasehold. The area under lease should be assigned the number from the original parcel with the addition of a decimal number to identify the leasehold. As an example, the tract of land where the lease occurs has been assigned PIN 6793 61 9429. That portion being leased should be assigned PIN 6793 61 9429.01, where applicable. If the entire parcel is being leased for an improvement, the same concept would apply; a parcel number for the landowner and a parcel number for the leasehold improvement.

H. Mineral Rights. In those instances where mineral rights ownership is severed from the surface rights ownership and proper documentation is provided, a parcel identification number should be assigned to the severed rights. All severed mineral rights ownerships, continuous within a section, should constitute one mineral rights parcel, regardless of the number of the surface rights parcels the severed rights encompasses.

I. Ownership Codes. The parcel index record shall be designed to accommodate an ownership code number to identify the different variations of real property ownership as follows.

0 = Ownership code number for fee simple title (to be used for split-offs of fee simple also).

1 = Ownership code number for identifying leasehold improvements.

2 = Ownership code number for identifying condominium unit ownership.

3 = Ownership code number for identifying mineral rights ownerships.
