Egress Window Installation in Oregon City, OR
Oregon City's Historic Review Board has put in writing what it wants an egress-sized window to look like. Conditioning a new triplex on a non-designated lot inside one of the city's historic districts in 2025, the board asked for windows "more compatible with the Historic design as well as alternate options for historically compatible windows that would meet egress requirements," and then said what those were: wood, aluminum-clad or fiberglass, never vinyl; one-over-one; wide horizontal windows swapped for paired small squares, except where a window has to serve as egress, in which case a larger single- or double-hung one-over-one, one pane above one pane, is accepted instead. That was a new-construction case, not a basement retrofit: new construction and large additions in the district go to the board whether or not the house on the lot is designated. It is still the clearest statement on record of what the board will approve when an opening has to be big enough to climb out of, and on a designated Oregon City house that is the question VResh Construction answers before the building permit is drawn.
Who reviews what
The code behind the first three rows is one sentence: no one shall "alter any historic site in such a manner as to affect its exterior appearance" without a certificate of appropriateness, the board's written approval, and the city's own list of what affects the exterior begins with "windows, doors, changes in siding material, and additions."
The window the board accepts
For a reviewed house, the board's window policy, Policy #10, is the map. It permits "wood, aluminum clad wood, and fiberglass clad wood windows" as replacements, allows vinyl only where the house was built with vinyl or aluminum, and bars interior grids. A like-for-like replacement that meets the policy is a staff decision with no separate historic permit. An egress window is not a like-for-like replacement: its opening is larger by definition, the policy says an enlarged opening needs a building permit, and that is what moves it out of the staff path unless staff finds it policy-compliant. So, on a reviewed house, the egress unit VResh proposes is the one the board has already described, a larger one-over-one in wood or clad wood with trim matching the house, on a rear or side elevation, and the certificate of appropriateness is applied for first. The board meets on the fourth Tuesday of each month; design-advice submissions are due 11 days before, and a submission sent to the board instead of being handled by staff can add a month or more to the schedule.
Below the bluff, and on it
Oregon City is a city of terraces: the first level on river alluvium, the second on flood silts over Troutdale gravel and clay, and the buttes above. The Geologic Hazards Overlay covers the steep slopes and mapped slide areas. A window well is a small excavation, by volume, of one to three cubic yards, but the overlay's list of regulated activities names excavation exceeding two feet in depth, whatever its volume, and a code-size well is deeper than two feet. So on an overlay lot, the city's Geologic Hazards Checklist is filled out, and the planner decides whether the well is exempt. The drain is a separate matter. The city names "concentrating water onto a slope" among the human triggers for landslides, next to cutting the toe of a slope and loading its top, and a well drain that daylights onto a hillside does exactly that. On a South End or Newell Creek lot, the drain is piped to the footing drain or an approved discharge, well away from the slope below the house.
One thing to know before a schedule is promised: the McLoughlin threshold is under discussion. In April 2025, the Historic Review Board held a work session to amend the rules governing alterations, additions, and new construction in the conservation district, so the rule that currently applies only to locally designated homes is the one the board has been examining. That does not change what applies to a house this month, and it is the reason the status of a particular address is confirmed at plan review.
Which houses, and what the application asks
About 41 percent of Oregon City's 14,650 homes were built before 1980. Two groups matter here. The 1970s are 19.1 percent of the stock on their own, the split-level and daylight-basement era on the terraces above the bluff, where one basement wall is often at grade, and the egress window is a framed opening rather than a cut through concrete. And 10.6 percent of the city's homes predate 1940, many of them in and around the McLoughlin and Canemah districts, with full basements and, often, the board's review; those are also the houses where every cut is lead-safe work.
One map comes before any of that. Oregon City administers a flood management overlay along the Willamette, the Clackamas and Abernethy Creek, and it defines a basement as an area with its floor below ground level on all sides, which is what a basement bedroom is; on a lot inside it, the floodplain administrator answers first. The city's hazard plan counted 38 flood insurance policies in force citywide as of 2018, suggesting the overlay reaches few houses and the check is quick.
Since January 1, 2025, Oregon City accepts building permit applications only through its own Citizen Self Service portal, and its submittal guidelines require that documents be "combined by type": the application as one file, the calculations as one, the drawings as one. The residential checklist asks for basement wall cross sections "showing placement of rebar," floor plans carrying "window size, location of smoke detectors," at least two elevations for a remodel, and engineer's calculations "when required or provided." Plans are drawn to scale, and the city sets a floor on that, too: a minimum scale of an eighth of an inch to the foot on 11-by-17 sheets, with type no smaller than 10-point. The building permit form has a line for the number of bedrooms, and the stamped plans "will need to be printed and available on the job site for inspections." The counter at 695 Warner Parrott Road is open Monday through Thursday, and next-day inspections are booked through the automated line "up until midnight the day before." None of that is hard; the portal is different from the cities next door, and a contractor who works across the region has to know which one is which.

The board's own words for what it wants are the ones to keep: wood, aluminum-clad or fiberglass, one-over-one, and where a window has to serve as egress, a larger single- or double-hung version of the same thing. If your house is on its list, that is the drawing to bring. Call or text (503) 272-6436.
