The honest answer is that it depends on your lot, and the homeowners who get it wrong usually skipped one step at the start.
This is one of the most common questions we get before an installation, and it's worth answering carefully. A fence built even slightly on the wrong side of a line can become a neighbor dispute, a survey expense, or in the worst case a fence that has to come back out.
Most homeowners go off memory, an old landscaping edge, or where the previous fence stood. None of those are reliable. Existing fences in particular drift over decades as posts are replaced one at a time, so an old fence line is evidence of where someone once built, not proof of where the boundary is.
A current survey with marked pins is what settles the question. If your property has recorded pins and you can locate them, that's your line. If you can't find them, a licensed surveyor can re-establish them. On tight urban lots this is money well spent before anything gets set in concrete.
Whether you can build right up to the line, or need to hold back from it, depends on local code and sometimes on the specific zoning of your lot. Corner lots, lots bordering a right-of-way, and lots with recorded easements are frequently treated differently than a standard interior lot. Height limits often change depending on whether the fence is in a front, side, or rear yard.
The practical step is to confirm the current requirements with the City of Beaverton or Washington County for your address before finalizing a layout — rules change, and what applied to a neighbor's project several years ago may not apply to yours. We cover the broader process in our post on whether a fence permit is required in Beaverton.
If your neighborhood has an HOA, its rules sit on top of local code, not instead of it. HOAs commonly restrict material, color, height, and which side the finished face has to point toward. Approval from an HOA does not substitute for meeting local requirements, and meeting local requirements does not exempt you from the HOA.
Utility and drainage easements can run through a back or side yard on a perfectly ordinary lot. You may still be allowed to fence across one, but the utility retains the right to access it — which can mean your fence section gets removed and not always replaced. Knowing where easements sit before you choose a layout avoids an expensive surprise later.
Not a legal requirement, but consistently the best predictor of how smoothly a boundary fence project goes. A short conversation before work starts prevents most of the disputes we see, especially when the two properties will share the fence line.
Confirm the boundary with a survey, confirm the setback and height rules with the local jurisdiction for your address, check your HOA and any recorded easements, and then design the fence. Doing it in that order costs a little time upfront and avoids the only fence mistake that's genuinely expensive to undo.
