Short answer? Probably yes.

Long answer? It depends on where you live, how tall the fence is, what it’s made of, whether it fronts the street, and whether you actually own the ground you’re planting posts in. That last one trips more people up than anything else, and it’s the one that ends in lawyers.

Let me walk you through what actually matters before you dig a single post hole.

First: Yes, You Probably Need a Permit

Most municipalities require a permit for any fence over six feet. A lot of them require one for anything over four feet in a front yard. Some require a permit for every fence, period, regardless of height. Some don’t require one at all until you’re doing something the neighbors call about.

There is no universal rule. That’s the whole point. Anybody telling you “you don’t need a permit for a residential fence” without knowing your ZIP code is guessing.

Here’s what to do:

  • Call your local zoning or code enforcement office. Not the state. Not Google. Your township, borough, or city. Ask two things: do I need a permit for a fence, and what are the height and setback rules on my lot?
  • Ask about corner lots specifically. If your property wraps around an intersection, you’ve got sight-line restrictions that can knock a six-foot fence down to three feet on one side. That rule exists so drivers can see kids on bikes. Don’t fight it.
  • Get the answer in writing or write down who told you what. Name, date, what they said. If somebody at the counter tells you “you’re fine” and the inspector shows up six months later with a different opinion, that note is what saves you.

Permits usually run somewhere between $50 and $300 depending on the town. Cheap. Way cheaper than tearing the whole thing out.

Second: Your HOA Is a Separate Problem

A permit from the town does not mean your HOA is okay with what you’re building. These are two different governments with two different rulebooks, and both of them can force you to rip the fence out.

I fixed a job in a townhouse development out past King of Prussia where the guy pulled his permit, built a nice six-foot cedar privacy fence, and got a letter from his HOA thirty days later telling him the community only allows black aluminum, four feet tall, and he had ninety days to comply. He’d checked with the township. He’d never opened the CC&Rs the title company handed him at closing. Cost him about eleven grand to redo the whole thing.

If you’re in an HOA:

  • Read your covenants before you buy materials. Look for the words “fence,” “boundary,” “screening,” and “architectural review.”
  • Submit your plan to the architectural committee. Yes, even if you think it’s stupid. Yes, even if your neighbor did whatever they wanted. Get approval in writing.
  • Assume the answer will be slow. Some committees only meet monthly. Plan accordingly.

Third: Where Is Your Property Line? Actually?

This is the one that gets people sued.

Everybody thinks they know where their property ends. The hedge, the driveway edge, that stake somebody’s cousin pointed at ten years ago. None of that is a legal boundary. A property line is defined by the deed and marked by survey monuments — usually iron pins or capped rebar driven into the ground at each corner.

On newer lots, those pins are still there. Sometimes flush with the ground, sometimes a couple inches under it. A cheap metal detector can find them in twenty minutes. Start where the deed says the corner is, sweep in circles, listen for the beep.

On older lots, especially anything built before 1970, the pins may be gone. Buried under decades of mulch, ripped out by a backhoe during a sewer replacement, or never set in the first place. If you can’t find them, you’re not guessing. You’re hiring a surveyor.

A residential boundary survey in the Philly metro runs roughly $600 to $1,000. More if the lot is weird-shaped or the records are a mess. That feels like a lot of money for some guy to walk around with a tripod for two hours. It isn’t. It’s cheap insurance.

Who Pays for the Survey? Read Your Contract.

Here’s the part most homeowners miss until it’s too late: almost every fence contractor’s contract puts the responsibility for locating property corners on the homeowner. Not the contractor. You.

If you sign a contract, tell the crew “the line runs from that tree to that shed,” and the fence ends up eighteen inches onto the neighbor’s lot, that is your problem. The contractor built where you told him to build. Your neighbor’s lawyer is going to have a real nice time with that.

Before you sign anything:

  • Read the section about property lines out loud. If it says the homeowner is responsible for identifying boundaries, that’s you.
  • If you’re not 100% sure where the line is, get a survey before the crew shows up. Not after.
  • Ask the contractor to note in writing which markers they’re building to. Iron pins, survey stakes, whatever. If it’s not documented, it didn’t happen.

The Practical Checklist

Before the first post hole:

  1. Call the zoning office. Confirm permit requirements, height limits, setbacks, corner lot rules.
  2. Read your HOA covenants. Submit plans for architectural review if required.
  3. Locate your property pins. Metal detector first, surveyor if you can’t find them.
  4. Call 811 at least three business days before you dig. Free. Federal law. Don’t skip it.
  5. Read your contractor’s contract, specifically the property line clause.
  6. Talk to your neighbor. Not a legal requirement. Just smart. A ten-minute conversation now beats a subpoena later.

Fences look simple. They’re not. The wood-and-nails part is the easy half. The paperwork and the property line are where jobs turn into disasters.

Do the boring stuff first. Then dig.
