Sliding Door Replacement in Beaverton, OR
Beaverton's property maintenance code reaches into owner-occupied houses. Gresham's, by contrast, is written for rentals. Beaverton's says "the provisions of this code shall apply to all residential property within the City of Beaverton," and it has a paragraph about doors. "Every door to the exterior of a dwelling shall be equipped with a lock designed to discourage unwanted entry and to permit opening from the inside without the use of a key or any special knowledge or effort." The same section continues: the hinge, lock and strike plate "shall be maintained in sound condition and good repair"; "when closed, the door shall fit reasonably well within its frame and be weathertight"; and "every door frame shall be constructed and maintained in relation to the adjacent wall construction so as to substantially exclude wind and rain from entering the dwelling." A violation is a Class 1 civil infraction, and the code adds that "each day of continuing violation shall be considered a separate offense."
The paragraph is written about the house you already own, and it is a fair description of what a 40-year-old aluminum patio slider in Beaverton has usually stopped doing, which makes it a useful list to hold a replacement door against. VResh Construction replaces sliding patio doors in Beaverton in the existing opening, with the sill pan and head flashing its main sliding door page describes, and this page is about what Beaverton adds: the code's four tests, the age of the doors that fail them, and the two rules that apply even though no permit does.
The four tests in the ordinance
A lock "designed to discourage unwanted entry."
The original latch on a 1970s slider is a hook that catches a keeper in the jamb, and on a worn door the hook no longer reaches. A new slider carries a multi-point or two-point lock in the stile, and the secondary foot bolt at the sill that manufacturers offer is the hardware built for the job; whether a given lock meets the ordinance is Beaverton's call, and a broom handle in the track is not hardware at all.
Opens from the inside without a key.
This is the escape half of the rule, and the code repeats it in its bedroom section: "every bedroom in a dwelling shall have at least one emergency exit for escape or rescue, either an openable window or exterior door." On a Beaverton house where a bedroom's only exit is a patio slider, the replacement is chosen so it opens with one hand from inside, and a keyed interior deadbolt on that door, which some owners ask for, answers a different worry and creates this one.
"Fit reasonably well within its frame and be weathertight."
A slider that has to be lifted to latch has usually lost its rollers, its track or both, and on an aluminum frame the track wears into a groove that no roller fixes. The parent page covers rollers and tracks; here, the point is that "weathertight" is the code's term, and the interlock between the panels, the weatherstrip at the jamb, and the sill dam are what make a new door meet it.
A frame that keeps "wind and rain from entering the dwelling."
This is the one a replacement door does not satisfy on its own, because it is about the frame and the wall around it. It is why VResh sets the new unit on a sill pan and laps head flashing into the wall's drainage plane; caulk at the old flange does not make a frame weathertight.
The door that fails them
Beaverton's housing has a single largest decade: the 1970s, with 20.3 percent of the city's roughly 43,700 homes built between 1970 and 1979, and the 1960s through the 1980s together making up about 45 percent. The city's own hazard plan, counting a different span, puts 41 percent of the housing before 1979. Those are the 1970s-era tracts across the city where the patio door on the back of the house is the builder's aluminum two-panel unit, single- or early double-glazed, with the original hook latch, and it is now 47 to 56 years old.
Three things about that door are Beaverton-specific. First, about a third of Beaverton's houses predate 1978, so the old frame comes out under the federal lead-safe containment the parent page describes wherever paint is disturbed. Second, the city's hazard plan ranks extreme heat as Beaverton's top hazard, after the 115-degree days of June 2021, and windstorm second, noting that "older buildings ... not built to withstand high winds" are the vulnerable stock. On a 1970s house, the west-facing aluminum slider is the wall that meets both of those, and its glass area is usually larger than any window in the house. Third, in Murrayhill and other associations with an architectural committee, the door is an exterior change: Murrayhill's committee asks for approval "before starting any exterior construction," its drawing checklist names "doors, windows (size, operating type)" and "muntin bar pattern," and its approvals expire after 180 days. That is a calendar item, and VResh asks about the association at the first call so the estimate can be drawn to whatever the committee wants to see.
Without a permit, but not without a code
Replacing a patio door in Beaverton in the same opening needs no building permit. Beaverton adopts the state residential code without changing that exemption, and the state's list is explicit: "replacing doors and windows with no structural changes" requires no permit, while "cutting a new window or door opening or changing the dimensions of existing openings" requires a permit. Widening a 6-foot slider to an 8-foot one, or converting the opening for a multi-slide, is the second case and goes to the city's building division with a header detail.
Exempt does not mean unregulated. Oregon's energy code files a glass door under windows, and the code carries two numbers for one: U-0.30 on the existing-building table for windows and glazed doors, and the 0.27 the state applies to a new window. Which one governs a replacement is the Building Division's answer, and it is asked before the door is ordered rather than after. Nor is there a rebate to chase in 2026: Energy Trust discontinued its Oregon windows and glass door incentive on January 1, 2026, and what remains is a southwest Washington program for NW Natural gas customers. So the glass is chosen for the house: low-e double pane with argon as the parent page's standard, a lower solar heat gain coating on a west or south exposure given the heat ranking above, and triple pane where a bedroom faces OR 217 or the rail line beside it, which are the highway and heavy-rail sources the city's comprehensive plan names when it lists "extra-thick windows" among the ways to answer them.

Try the four tests yourself
Go out to the door and work down the list. Does the latch catch without lifting the panel? Does it open from the inside in one motion without a key? Does the panel meet its frame the whole way along? Is there daylight, or a draft, where the frame meets the wall? A door that fails two of those is the door this page is about, and a replacement in the same opening, on a sill pan and under head flashing lapped into the wall, is aimed at all four, with the fourth depending on what the wall behind the old frame turns out to be.
