Full Breakdown
The DMU performance standards require commercial outdoor storage yards, loading docks, and mechanical equipment, including HVAC equipment, to be shielded by a building or solid structure with no gaps from the line of sight of outdoor activity areas tied to residences within 300 feet. An identical standard applies in the CMU mixed-use district. The rule is limited to these mixed-use zones; it is not a citywide HVAC standard.
Violations & Fines
A development that fails to screen qualifying mechanical equipment can be held out of compliance with its site plan/design review approval for the DMU or CMU district, requiring retrofit screening before final approval.
