The residential zoning district (RZD) provides areas in which existing and new one- and two-family dwellings will be free of the conflicts that arise where residential uses are mixed with commercial or industrial enterprises, or where low density residential uses are mingled with higher density residential developments. Home businesses are permitted, but only in compliance with performance standards that require such businesses to be compatible with neighboring homes. Schools, churches, daycare centers, and parks are also allowed, but only after public review and approval of a class II permit ensures that they are compatible with the surrounding residential environment. (Ord. 2000-02, 3-3-2000)

1. Uses: The permitted uses in the RZD shall be:
   
   Accessory uses and buildings customarily associated with the uses permitted in this zoning district, including the conditional uses.
   
   Home businesses, in compliance with the detailed performance standards of chapter 11 of this title.
   
   Lot splits and plat amendments.
   
   Minor utility installations.
   
   One- and two-family dwellings.
2. Permit: A class I permit shall be required for any lot split, plat amendment, or permitted use or building, unless that lot split, plat amendment, use, or building is specifically exempted from the requirement for a permit by TCC 9.10. (Ord. 2000-02, 3-3-2000)
   

The conditional uses that may be permitted, upon approval of a class II permit, in the RZD shall be:

1. Schools, churches, daycare centers, and parks.
2. Subdivisions designed for occupancy by one- and two-family dwellings, as permitted in this zoning district. (Ord. 2000-02, 3-3-2000)

The specification standards for development within the RZD shall be as shown in TCC 9.14.070. (Ord. 2000-02, 3-3-2000)

Development in the RZD shall be subject to the general performance standards of TCC 9.22, as applicable, and these additional specific performance standards:

1. Accessory Buildings: Accessory buildings shall be permitted in side or rear yards only, and are subject to the setback requirements of TCC 9.14.070 Table 1. Accessory buildings shall also be separated from other buildings on the same lot by at least five feet (5').
2. Outdoor Storage:
   1. Screening: Outdoor storage shall be confined to side or rear yards, or effectively screened from public view using a landscaped buffer that includes an opaque hedge, fence, or wall. The materials and color of screening fences or walls shall be compatible with those of the dwelling on the lot.
   2. Exception: Construction equipment and materials may be temporarily stored in a front yard, but shall be removed promptly upon completion of construction. The parking of a currently licensed vehicle is not outdoor storage.
3. Livestock On Residential Premises: Livestock may be kept in the RZD, but only in compliance TCC 4.08.130.
4. Landscaped Buffers: New subdivisions that are in the RZD, but adjoin other zoning districts, may be required to install and provide for the maintenance of landscaped buffers in compliance with TCC 9.32. (Ord. 2000-02, 3-3-2000)

This zoning district is designed for use within the city, where homes have access to central water and sewer, and where they meet state standards and approval. (Ord. 2000-02, 3-3-2000)

1. Definitions For Table 1: Definitions of the principal terms used in this table are provided below. Every lot has one front, one rear, and two (2) side yards.
   
   BUILDING HEIGHT: Measured from average grade to the highest part of the structure. Antennas, vents, machinery housings, and similar nonstructural projections above the roofline are not included.
   
   CORNER LOTS: Any lot that is bordered by more than one street.
   
   INTERIOR LOTS: Any lot that is bordered by only one street.
   
   INTERIOR LOTS (FLAG LOTS): Any lot that otherwise meets the requirements of this section to allow development and building, that does not border any city street, and:
   1. That has access bordering a city street provided by an easement or deeded strip of land which is at least sixteen feet (16') wide and otherwise adequate as a driveway. This driveway or approach cannot be included to create 0.4 acre in the flag lot.
   2. "Frontage", as applied to such a lot, means that one side of the lot must be at least one hundred ten feet (110') long, not including the length of the driveway that accesses the property even if it is part of the lot purchased.
   3. The creation of such a lot must not render the remainder of the original lot out of compliance with the planning and zoning ordinance or any other requirement of this code.
   4. Such lots can only be used for single-family dwellings.
   5. Building on a flag lot must comply with all building standards and setbacks.
   6. The city would have no responsibility for maintaining access roads/driveways.
   LOT COVERAGE: The portion of the lot covered by buildings, including accessory buildings, sidewalks, driveways, and other hard surfaces.
   
   SETBACKS:
   1. The front setback is the distance, at the nearest point, from the street right of way to the outer foundation wall of the principal building, or to any projection of that building which extends more than three feet (3') beyond the outer foundation wall.
   2. The rear setback is the distance, at the nearest point, from the alley right of way, or the property line that is parallel, or more or less parallel, to the street, to the outer foundation wall of the principal building, or to any projection of that building which extends more than three feet (3') beyond the outer foundation wall.
   3. The side setback is the distance, at the nearest point, from a property line that is perpendicular, or more or less perpendicular, to the street, to the outer foundation wall of the principal building, or to any projection of that building which extends more than three feet (3') beyond the outer foundation wall.
