Vancouver's code does a piece of arithmetic that most cities leave to the homeowner. In the chapter that establishes the Noise Impact Overlay District, the city explains why the district exists and then, wall by wall, how sound enters a house. On doors it says this: "Acoustically, doors are even weaker than windows, and more difficult to treat. Any door will reduce the insulation value of the surrounding wall. The common hollow-core wood door has an STC rating of 17dB. Taking up about 20% of the wall, this door will reduce a 48 STC wall to 24 STC." A solid-core door, well sealed, brings the same wall back to 33. And then a line that reads like a builder's instruction: "In any case, no mail slots or similar openings would be allowed in exterior doors." That chapter has been on the books since 1985 and was carried into the city's rewritten Title 20 in 2026 as Chapter 20.560, with the door paragraph carried over word for word.
The map behind the chapter
The district is a map, drawn on the 65 Ldn contour, and its sources are the ones the chapter names: Portland International Airport, the Burlington Northern railroad, the I-5 freeway, and Pearson Field, which the city reports at 144 operations a day. Large-scale maps are kept at the community development department, and a building or development permit for residential use inside the line carries a noise disclosure statement recorded with the county auditor, so a homeowner in the district may already have that statement in the title file. The chapter's construction standards, the Noise Impact Reduction Plan, and the 45 Ldn interior target apply to new residential construction, expansions of 10 percent or more, and rebuilds costing more than three-quarters of the house's value. A replacement door is none of those. What the chapter offers a homeowner replacing a door inside the line is the city's own account of where the wall is weakest, and VResh Construction treats that account as the specification.
The chapter's numbers, applied
The city's example is a hollow-core door, which is no longer sold as an entry door, but its STC rating carries over. A solid-core slab runs roughly 10 points above a hollow one, and with the seal the chapter describes, that is what turns its 24 into 33. A foam-filled fiberglass or steel slab is the light option; its rating comes from its skins and its seal rather than its mass. Where a maker publishes an STC figure for the slab, it goes on the estimate. Where none is published, solid core is the safe assumption and the seal does the rest. "Well sealed" is the chapter's phrase, and it is most of the work: compression weatherstrip on three sides, a sweep that meets the threshold along its whole length, and a threshold set so the sweep lands on it, because an open quarter inch at the sill is what the wall is rated at. The chapter names one opening it will not allow, a mail slot, and VResh does not cut one in an entry door inside the district. A lite in the slab or a sidelight beside it is ordinary door glass, thinner than the slab, and it is specified on its own rating.
The overlay itself asks nothing of a replacement door. Whether the work needs a permit, and whether that permit carries the district's disclosure condition, is the city's call, and VResh asks.

The chapter's numbers on the estimate
Inside the district, the estimate names the slab, the seal, and the glass, with a published sound rating where the maker gives one and a solid core where none is published, and the door has no mail slot in it. Call or text (503) 272-6436.
