[Code 1975, § 39-47; Code 1992, § 32-176]
The R-1 Single- and Two-Family Residential District is established as a district in which the principal use of land is for single- and two-family dwellings. For the R-1 District, in promoting the general purpose of this chapter, the specific intent of this section is to:
(1) 
Encourage the construction and the continued use of the land for single- and two-family dwellings.
(2) 
Prohibit business, commercial or industrial use of the land and prohibit any other use which would substantially interfere with development or continuation of single- and two-family dwellings in the district.
(3) 
Encourage the discontinuance of existing uses that would not be permitted as new uses under this chapter.
(4) 
Discourage any land use which would generate traffic on minor or local streets other than normal traffic generated by the residences on those streets.

The following uses shall be permitted in the R-1 District subject to the conditions imposed and subject further to the approval of the Planning Commission:
(1) 
All permitted uses after special approval in the R District, subject to the terms and conditions therein.
(2) 
Professional or business office approval shall be conditioned upon the meeting of the building height limit, side yard width, rear yard depth, front yard depth and plat coverage required in the district in which the site is located and conditioned further that the automobile parking spaces shall be in accordance with § 52-772. If there is a question as to whether or not a use is indeed an office, the Planning Commission shall decide first if an occupation is suitable as an office per the definition before the special permit is granted.
A professional office shall not be located in the same structure or on the same lot as a residential use. If an existing residential structure is converted to an office, the entire structure shall be used for said office. Said building shall be renovated according to the existing building code for a commercial use, including barrier-free codes. The parking lot shall be paved, drained, and screened from any adjacent residential use.
(3) 
A temporary building for commerce or industry for a period of not more than one year, when incidental to the erection or servicing of structures or uses permitted in such districts.
(4) 
Governmental uses when found to be necessary for the public health, safety, convenience or welfare.
(5) 
Family child care home, state licensed for six or fewer children, subject to the following conditions:
a. 
For each child cared for, there shall be provided and maintained a minimum of 100 square feet of outdoor play area.

a. 
Said parking lot must be on the same property as the existing business or multifamily use it is intended to serve or adjacent to an existing parking lot. A renovation of an existing lot does not need a special approval use permit, only the expansion of said lot.
b. 
Such parking lot shall be used only for the parking of vehicles with no repair work or servicing of any kind.
c. 
Adequate lighting shall be provided and so arranged or reflected away from residences in the area as to cause no annoying glare to such residential property.

The unit must be a certified residential rental unit in conformance with Chapter 10, Buildings and Building Regulations, Article V, Rental Certification, of the City Code of Ordinances.
