This designation is intended to allow for a single-family residential use or a compatible low-intensity commercial and office use, or a combination of residential/nonresidential uses within existing residences and auxiliary structures. It is intended to encourage a mix of appropriate land uses within transitional neighborhoods that are adjacent to more intensive commercial, office and industrial areas. Low intensity commercial and office uses would be allowed which would not result in significant land use compatibility impacts, but which would be greater than that which would be permitted through home occupation regulation.

The residential business (RB) district has been created to implement the goals, objectives and land use designations of the General Plan.

All uses allowed in the R-2 base district pursuant to Table 13.10.030A are allowed in the R-B district. In addition, uses listed in Table 13.21.030A shall be allowed as indicated in the column beneath the residential business district heading. Where indicated with the letter "P," the use shall be a permitted use in that district. Where indicated with the letter "C," the use shall be a conditional use subject to a conditional use permit in that district. Where indicated with the letters "MC," the use shall be a conditional use subject to a minor conditional use permit in that district. Where indicated with a dash "—," or if a use is not specifically listed in Table 13.21.030A and is not subject to the use determination procedure contained in Section 13.04.040, the use shall not be permitted in that district. This section shall not be construed to supersede more restrictive use regulations contained in the conditions, covenants and restrictions of any property or dwelling units. However, in no case shall uses be permitted beyond those allowable in this section. In the event a given use cannot be categorized in one of the districts by the Director, the use determination procedure outlined in Section 13.04.040 shall be followed.

The site development criteria are intended to provide minimum standards for residential business development. These site development standards should be used in conjunction with the design guidelines, which are set forth in the development review manual. This section shall not be construed to supersede more restrictive site development standards contained in the conditions, covenants and restrictions of any property or dwelling unit.

Any equipment, whether on the roof, side of building, or ground, shall be screened. The method of screening shall be architecturally integrated in terms of material, color, shape and size. The screening design shall blend with the building design. Where individual equipment is provided, a continuous screen is desirable.

On-site parking shall be maintained for the residential use in accordance with Chapter 13.24. Any additional on-site parking shall not occupy more than 50% of the required front yard.
