I,TOPIC;1 Rooftop Antennas: Commercial Zones
INTERPRETATION: Regarding the process necessary to place several panel type antennas on the roof of a
commercial building in the City of Tigard;
Such a facility is regarded in the Community Development Code as an appendage to the
principle structure and it does not require any City land use permits. A building permit is
necessary prior to placement of the antennas on the roof.
This determination is based upon the provisions of the following Code sections:
1. Section 18.98.010 exempts rooftop "aerials" from the building height requirements of
the applicable zone.
2. Section 18.144.020 considers such a rooftop antenna as part of the principle
structure and not an accessory structure.
3. Section 18.42.020.B.7 includes telephone transmitters and other related facilities that
have a "significant visual impact" as utilities, which are conditional uses in all zoning
districts. I find that the proposed antennas are not utility facilities because they have
minimal visual impact.
