Anoka, Minn., Code of Ordinances ch. 50, art. II § 50-52

(a) The purpose of this section is the limitation of rental licenses issued to detached single-family residential dwelling units located on single-family lots.
(b) In any R-1, R-2, R-3, R-4, MS zoning district, no more than ten percent of the single-family lots on any block shall be eligible to obtain a rental license, unless a temporary license is granted by the city council as provided herein. Table 1 indicates how many single-family lots per block are able to be licensed as a rental property based on the number of lots that exist in a block.
TABLE 1 Lots/Block Rental Units Allowed 1-14 1 15-24 2 25-34 3 35-44 4 45-54 5 55-64 6 65-74 7 75-84 8 85-94 9
(c) The following guidelines shall apply to determine eligible blocks and lots:
(1) For the purposes of this section, a block shall be defined as an area of land enclosed within the perimeter of streets, watercourses, public parks, municipally owned lots and city boundaries and further defined by an official map maintained by the city.
(2) This section shall apply to legally conforming lots of record and legally nonconforming lots of record. For the purposes of this section, lots of record may also be referred to as properties, property or lots.
(3) If a block contains more than one type of zoning district, only R-1, R-2, R-3, R-4, MS zoning district lots shall be included in the calculation of the total number of lots per block.
(4) Business/commercial, institutional, industrial uses located in an R-1, R-2, R-3, R-4, MS zoning district shall not be included in the calculation of the total number of lots per block.
(d) If the number of rental properties meets or exceeds the permitted number of rental properties per defined block on the effective date of the ordinance from which this section is derived, no additional rental licenses shall be approved for the block, unless a temporary license is granted by the city council as provided herein. Existing rental licenses may be renewed; however, should a rental license not be renewed, terminated due to the sale of a property by the current license holder, transfer of property ownership occurs, or if the rental license is revoked or lapses, the rental license shall not be reinstated unless it is in conformance with this section and other applicable sections of this Code.
(e) If the number of rental properties meets or exceeds the permitted number of rental properties per defined block on the effective date of the ordinance from which this section is derived, a property owner may request a temporary license to allow an additional rental property for that block. The city council may grant or deny a temporary license in its sole discretion. Circumstances justifying consideration of a temporary license may include such situations as the homeowner's deployment for military purposes or temporary relocation out of state for employment-related reasons, where the homeowner's absence from the state is expected to last for at least one year. Persons requesting a temporary license must make an annual application to the city. No property owner shall hold a temporary rental license for the same property for more than two consecutive years, and it is expected that the homeowner will reestablish residency in the property upon the termination of the temporary license.
(f) For the purposes of this section, sober house licenses issued to single-family homes pursuant to section 50-189 shall be considered rental dwelling licenses when determining the number of eligible licenses available per block as regulated by this section. If the number of licensed rental properties meets or exceeds the permitted number of rental properties per defined block, no additional sober house licenses shall be approved for the block.
