Do You Need a Permit to Replace Siding in Beaverton?

A straight re-side that does not touch the structure is light on paperwork, but there are two Beaverton catches worth knowing. First, if the old siding comes off and the sheathing or framing behind it has to be replaced, that is structural work, and it goes through the City of Beaverton's permit system (the online BEPS portal). We handle that permit when the wall calls for it. Second, if your house is a designated city landmark, Beaverton Development Code 40.35 treats a change to the exterior finish material as an Alteration of a Landmark, a Planning Commission review, and new material has to match the old in composition, design, color and texture. We check your address against both before we quote.

The Median Beaverton House Was Built in 1987

The Census Bureau's 2020-2024 survey puts the median year built in the City of Beaverton at 1987, and counts 42,771 housing units. More than a third of them, 37.6%, went up before 1980, and the single biggest building decade was the 1970s with 8,505 homes, just ahead of the 1980s at 7,676.

That is the heart of the siding problem here. A house built in the 1970s or early 1980s is now 40 to 50 years old, and the original wood, plywood or hardboard siding it was built with has had decades of valley rain driven into its seams. By the time the paint stops holding and the bottom courses go soft, the boards are usually past saving. Tearing it all the way off is the only way to see what the water has done to the sheathing behind it, and it is the step a lot of quotes quietly skip.

The newer end of town is different. Out at South Cooper Mountain, where more than 1,600 homes have gone up and thousands more are planned, the siding is the builder-grade material the house came with, and the real question is how well it was flashed when it went on. In both cases we pull the old material and read the wall before we price the job.

From Tear-Out to Final Trim

1. Estimate and written price. We measure every wall, check your street and whether the house is a landmark, and hand you a written price that names the James Hardie product and the trim for your house.
2. Tear-out and haul-away, listed on your written estimate: the walls come down to bare sheathing and the debris rides out with us, not into your driveway.
3. Wall check with you. Soft sheathing or framing in a wet-valley house is common around Vose and the older downtown streets; if we find it, you look at it with us before it is closed up, and the city permit for that repair is ours to pull.
4. Moisture barrier and flashing, lapped so water drains out, around every opening and roof line.
5. Hardie boards and trim go on per the manufacturer's nailing schedule, caulked and painted-edge finished.
6. Final walkthrough, and the limited 5-year workmanship warranty goes home with you in writing.

Replacing windows at the same time? It is the best moment to do both, since the flashing and trim around each opening go in once. See window replacement in Beaverton, or the product details on our James Hardie siding page.

City or county? Plenty of homes with a Beaverton mailing address sit outside the city limits. Aloha, Cedar Mill, Cedar Hills and Bethany are unincorporated Washington County, so their permits run through Washington County Building Services in Hillsboro, not the city. We check which one your address falls in before we quote, because it changes how the permit is handled. We also install fences here: fence installation in Beaverton.
