You step onto the patio with your coffee, look up, and there it is again: the neighbor’s upstairs window, pointed straight at your lounge chairs. Nobody is waving, nobody is doing anything wrong, and yet the yard you pay for suddenly feels like a stage. So you start pricing 10-foot panels online, and wondering whether a row of fast trees would solve it by summer.
Wanting privacy is not petty, and it is not your fault that the houses were built this close. But the fastest fixes are also the ones most likely to break a local rule or start a feud. The good news is that the legal options are wider than most people think, once you know where the lines are.
The Rules That Actually Apply

Fence height is set by your city or county, and sometimes by your HOA. As a general pattern, residential fence limits run about four feet in front yards and six feet in backyards. Local codes also decide how far a fence must be set back from the property line, and HOA covenants often restrict materials as well as height.
Plants are not automatically exempt. A row of trees or bushes along a property line usually counts as a fence, and many ordinances cap these natural fences somewhere between five and eight feet. Then there are spite fence laws: a structure that serves no reasonable purpose except to annoy a neighbor can be declared a nuisance, and the neighbor can sue to have it removed. Courts have applied that to trees too. In a 2002 California case, Wilson v. Handley, trees planted along a property line to block a view were ruled a spite fence.
What You Can Put In Front, Without A Feud
The trick is geometry. A screen at the property line has to be tall enough to block an upstairs window across your whole yard. A screen placed right next to the spot you actually use, the patio, the hot tub, the reading chair, only has to cover that corner, and it can do it at a lower height. The closer the screen sits to what you want hidden, the less height it needs.
- A freestanding screen or trellis by the seating area. Set back from the line and sized to your patio, it shields the spot that matters. Check whether your code treats it as a fence before you buy.
- Overhead cover. A pergola with slats, a shade sail or a large umbrella blocks the view from above, which is exactly where an upstairs window looks from.
- Tall planters instead of a hedge on the line. Grasses or shrubs in big containers can move with you and don’t form a row along the boundary.
- A fast evergreen, kept in check. Thuja ‘Green Giant’ can grow 3 to 4 feet a year in good conditions, according to NC State Extension, but it can reach 40 to 60 feet tall. If you plant it, budget for trimming to your local hedge limit.
If your yard is short on depth, choose the fence color with care too, since a darker tone can make a small garden look bigger.
How To Keep It Neighborly
Before you build, call your city’s planning or zoning office, read your HOA covenants, and ask whether a permit is needed. Then talk to the neighbor. A friendly heads-up that you’re adding a screen by the patio rarely offends anyone, while a surprise wall of trees along the line almost always does.
The honest limit: rules vary widely from town to town, and spite fence laws differ by state, so treat these numbers as a starting point, not legal advice. If a dispute is already brewing, or you’re unsure where the property line is, a survey or a local real estate attorney is cheaper than a lawsuit.
Shield the spot you use, not the whole yard, and check the code first. That’s the trick.
