9-200.020 - LAND USE REGULATIONS

Table 9-200.020-1 prescribes the land use regulations for the Residential zones. Use types are defined in Chapter 9-901, Updated Use Type Classifications; key terms used in the classifications are defined in Chapter 9-900, Terms and Definitions. In cases where a specific land use is not defined, the Zoning Administrator shall assign the land use a classification that is substantially similar in character. Use classifications and sub classifications not listed in the table or not found to be substantially similar to the uses listed in the table are prohibited. Numbered limitations for a specific use in an individual zone ("L1, L2, etc.") refer to limitations listed at the end of the table. The right-hand column in the table includes specific section references for other regulations in this Title, in Chapter 9-409, Standards for Specific Uses and Activities, and in other chapters. Zoning Compliance Review and permitting procedures are in the 800 Series.

TABLE 9-200.020-1: USES IN RESIDENTIAL ZONES

Notes:

L1 Allowed on the ground floor of a residential building with an Administrative Use Permit. L2 An Administrative Use Permit is required if more than 2,500 square feet.

(a)

Expansion of Uses and Structures. Uses or structures that require discretionary review may be expanded with a Zoning Compliance Review, provided the following conditions are met:

(1)

The proposed expansion or construction of a structure involves less than a 25 percent increase in the approved floor area as shown on the most recent land use permit or Zoning Compliance Review on file, but no more than 10,000 square feet;

(2)

The proposed expansion involves less than a 25 percent increase in the developed area of the site; and

(3)

The proposed expansion will not have a substantial, adverse effect on adjacent property and on the trafficcarrying capacity of local streets.

(4)

The expansion complies with existing requirements of agencies having jurisdiction and any other appropriate regulatory agency.

Where conditions in Subsections (1) through (4) of this Section are not met, the level of review for the expansion shall be the same as the level of review required in Table 9-202.020-1 for a new use.

(b)

Change in Use. Any change in an existing use to a new use that requires a land use permit shall be permitted without a land use permit, provided the Zoning Administrator finds that the proposed use:

(1)

will have no greater impact than the existing use; and

(2)

occupies the same floor area as the existing use.

The Zoning Administrator reserves the right to require a Zoning Compliance Review in lieu of the land use permit or to allow a minor expansion, as needed.

(c)

Accessory Uses and Structures. Accessory uses and structures permitted, not permitted, and conditionally permitted are set forth in Table 9-200.020-2. Accessory uses and structures not specifically listed in Table 9-200.020-2 are allowed with a Zoning Compliance Review if the primary use is permitted; they require an Administrative Use Permit if the primary use requires either an Administrative Use Permit or a Conditional Use Permit. All accessory uses are subject to the requirements of Section 9-409.040, Accessory Uses.
