Planning - Screening of rooftop equipment

Unified Development Ordinance Article 8, Section 8.180.E Roof mounted equipment – All roof-mounted equipment shall be screened entirely from view by using parapet walls at the same height as the mechanical units. For additions to existing buildings that do not meet this standard, individual screens will be permitted, with the design subject to approval by the Director. Action required: Make needed corrections to drawings that provide details as to how mechanical equipment will be screened from all 4 sides per referenced UDO section. 3/8/23 - not addressed 3/14/23 - Existing parapets are adequate per architect. To be field verified.

IMC 306.5 Equipment on roofs

2018 IMC 306.5 Equipment and appliances on roofs or elevated structures.
