(A) General description. This residential estates district is intended to provide for an intermediate single-family district with the smallest size lots that are appropriate for single-family development in areas not served by public sanitary sewer. This district typically would be considered within an area that can be served with an acceptable response time by police and fire protection. The development regulations in this district are intended to protect homeowners and homes within this district from the density found within the urbanized areas of the city that are served by all public utilities and thereby maintaining the type of density, setbacks, open space and other amenities conducive to a rural residential development setting.
(B) Permitted uses. The following shall be permitted as uses by right; provided, they meet all the development regulations of this section as well as other applicable city regulations and ordinances:
(1) Single-family dwelling;
(2) Park, community building, golf course, fire station, police station, water wells, lift stations or open space, owned by the city or other governmental or non-profit entity;
(3) Property owners’ association green space, meeting or recreation facility;
(4) Elementary or secondary school, no residential facilities included;
(5) Church, synagogue, mosque or temple, including sanctuary, pastor’s family residence and secondary buildings, subject to a minimum net lot area of three acres;
(6) Day care home;
(7) Home occupation;
(8) Residential sales office; this use shall not be interpreted to permit the construction of or moving in of a commercial building for a residential sales office. Any residential sales office used in conjunction with the development of a subdivision shall be limited to a maximum size of 400 square feet and shall be removed upon completion and sale of all lots within the subdivision. The 400-square foot restriction shall not apply to a newly constructed residential structure which is being used as a temporary sales office and/or show home. However, any temporary sales office shall cease to operate as such upon completion of all lot sales within the development in which it is located. No structures, temporary or permanent, shall be used to conduct business within the subdivision or development where it is located other than a permitted home occupation or residential sales office as authorized in this section. If the covenants and restrictions of a subdivision are more restrictive than this section, then those covenants and restrictions shall apply.
