A. House or premises numbers shall be determined by adding two digits to the block number in which such house or premises is located. The block number shall be obtained by taking the number of the nearest street or avenue to the appropriate base line. Block numbers shall be obtained from streets or avenues only, and no consideration or change in block numbers shall be made by the intersection of a place.

B. Consecutive numbers shall be assigned on streets or places running east-west, for each 20-foot interval commencing from the nearest avenue intersection to the west of the house or premises.

C. Consecutive numbers shall be assigned on avenues for places running north-south, for each 20-foot interval from the nearest street intersection with the numbers beginning at the end of the block nearest the base line.

D. The houses or premises located on the south and/or west side of such streets, avenues, places or ways shall receive odd numbers and the premises or houses on the north and/or east side of such ways shall receive even numbers. (1961 code § 10.08.090.)
