Full Breakdown
PTMC 17.30.155(F)(7), part of the mandatory design review standards for the uptown commercial subdistrict of the Historic Overlay District, requires that noise-producing mechanical equipment such as fans and heat pumps be sited or shielded to minimize noise reaching neighbors and the street. An applicant seeking a certificate of approval must back this up with equipment specifications and/or noise-impact calculations, not just a design sketch, before the Historic Preservation Committee and planning director sign off.
Violations & Fines
No certificate of approval issues for the project until the applicant demonstrates, with equipment specs or noise calculations, that adjacent-property noise is minimized; design review under Chapter 17.30 PTMC is binding on the permit.
