17-9-0202-A General. Home occupations are accessory uses to uses in the household living category. The regulations of this section are intended to ensure that home occupations will not be a detriment to the character and livability of the surrounding neighborhood. The regulations are intended to ensure that the home occupation remains subordinate to the residential use, and that the residential viability of the dwelling is maintained. The regulations recognize that many types of work can be done in a home with little or no effect on the surrounding neighborhood.
17-9-0202-C Standards. A dwelling unit may be used for one or more home occupations subject to compliance with all of the minimum standards in subsections (e), (f) and (g) of Section 4-6-270.
17-9-0203-A Satellite dish antennas up to one meter in diameter are permitted as accessory uses in all zoning districts. Subject to 47 C.F.R. 1.4000, as amended, and other applicable law, and subject to lawful restrictions on the use of common areas, all satellite dish antennas up to one meter in diameter shall be installed and maintained as set forth in paragraphs (1) through (3) below:
(1) All satellite dish antennas shall be placed in locations that are not visible from any street adjacent to the property on which such equipment is located. Pursuant to this paragraph (1), no satellite dish antenna may be installed or placed between the facade of a building and any street adjacent to the subject property, unless the device is wholly within a balcony or patio area that is under the exclusive use or control of the user. If compliance with this paragraph (1) is not technically feasible (i.e., compliance would result in a material delay or reduction in signal reception or significant additional cost to the user), the television access provider or installer shall provide the user of the equipment with a signed statement certifying that the satellite dish antenna cannot be installed in compliance with Section 17-9-0203-A(1) based on actual testing conducted at the property. A copy of the certification form shall be provided to the user, and a copy shall be maintained at the office of the installer or provider.
(2) If compliance with paragraph (1) is not technically feasible, and the television access provider or installer has issued a certification in accordance with paragraph (1), satellite dish antennas may be placed in locations that are minimally visible from any street adjacent to the subject property. For purposes of this paragraph (2), compliance with the “minimally visible” standard shall mean that the satellite dish antenna is (a) shielded from view from adjacent streets to the greatest extent possible by landscaping, lattice, fencing or structural or architectural elements of the building on which the satellite dish antenna is located (e.g., a balcony, bay window, chimney, dormer or parapet), and (b) if side-mounted, attached to a building wall facing the subject property's interior side property line and set back a minimum of ten feet from any building wall facing an adjacent street.
(3) All satellite dish antennas and associated mounting equipment and hardware shall be disconnected and removed when such devices are no longer in service.
1. Roof-mounted, pole-mounted antennas may be erected on the roof or attached to a principal building, provided the maximum height of the installation does not exceed 16 feet in height above the building on which it is to be located.
2. Ground-mounted satellite dish antennas must comply with all setback requirements of the zoning district in which it is to be located.
3. A building permit is required for each satellite dish antenna installation.
Editor's note – FCC Order DA 21-38, entered on January 11, 2021, ruled that paragraphs (1), (2) and (3) of Code Section 17-9-0203-A, regulating placement of satellite dishes, are federally preempted.
