§ 151.071 HOUSE NUMBERING SYSTEM.
   The standard method of assigning house numbers to each side of the street is as follows:
   (A)   On the east and west avenue, the even numbers to be assigned to the north side of the avenue and the odd numbers assigned to the south side of the avenue.
   (B)   On the north and south avenue, the even numbers to be assigned to the east side of the avenue and the odd numbers assigned to the west side of the avenue.
   (C)   On avenues with a deviation of more than 45 degrees from the north-south base line, the even numbers to be assigned to the north side of the avenue and the odd numbers assigned to the south side of the avenue.
   (D)   On avenues with a deviation of 45 degrees or less from the north side base line, the even numbers to be assigned to the east side of the avenue and the odd number to be assigned to the west side of the avenue.
   (E)   Circle streets are assigned numbers in staggered sequence to the number sequence of the drive, avenue or parkway on which it originates and terminates.
   (F)   Dead end roads are assigned numbers as if the road continued through, beginning with the smallest number of sequence at the road origin.
   (G)   Courts are assigned numbers conforming to the numerical sequence of the drive, avenue or parkway on which it originates.
   (H)   On a street that deviates 45 degrees or more (measured at the point of deviation) the number sequence will change accordingly.
   (I)   One-family dwellings and duplexes: one number will be assigned to each residential unit determined by the location of the principal entrance.
   (J)   Multiple-family dwellings: a number will be assigned to the entire structure with individual numbers or letters assigned to each dwelling unit starting with the number “1.” Multiple dwelling units consisting of two or more floors must designate each floor starting from the bottom up in a sequential order.
   (K)   Hotels and motels: a number will be assigned to the front entrance of the hotel and motel with individual numbers of letters assigned to each unit starting with the number “1.”
   (L)   Business structures: a number will be assigned to each entrance, but only one number per building establishment for each street frontage.
   (M)    Split lots: a structure located on two or more lots will be assigned a number determined by the location of the fronting entrance measured from the preceding grid line.
   (N)   Blocks: a structure located on the entire length or width of a grid block will be assigned a number determined by the location of the fronting entrance.
   (O)   Corner lots: a structure located on a corner lot will be assigned a number determined by the principal entrance. If the structure is so located that it would be considered fronting on either street, then it would be assigned a number determined by the north-south number sequence.
   (P)   Each principal building or structure must display address numbers. Address numbers must be a minimum of four inches in height. Address numbers must be placed on the structure with an unobstructed view from the street. Numbers must be illuminated, reflectorized or of a contrasting color to the background. Background must maintain a minimum six inch perimeter around numbers.
