Introduction
You can measure perfectly, buy exactly the right materials, and build a beautiful fence — and still be ordered to modify or remove it. Fences sit at the intersection of zoning codes, HOA rules, utility easements, and neighbor law, and every one of those is local.
The Privacy Fence Calculator handles quantities; it can’t check your local code. This guide covers the compliance checkpoints every privacy fence project should clear before materials are ordered: permits, height limits, HOAs, setbacks, easements, and the finished-side rule. When in doubt at any step, your local building authority (the AHJ — Authority Having Jurisdiction) is the final word.
Permits: Assume You Need One
Many US jurisdictions require a building permit for fences above a threshold height — commonly 6 ft (1.83 m), though some require permits for any fence. The permit process typically asks for: a site plan showing the fence location relative to property lines, fence height and material, and sometimes HOA approval documentation.
Permit fees commonly run $50–$200. Skipping the permit risks a stop-work order, fines, and — worst case — being required to bring a finished fence into compliance after the fact, one of the costliest errors in the common mistakes guide. Apply early: approval can take days to weeks, and you don’t want materials arriving before permission does.
Height Limits
Typical US patterns (verify locally — these vary widely):
| Location | Common height limit | Metric |
|---|---|---|
| Back yard | 6 ft | 1.83 m |
| Side yard | 6 ft | 1.83 m |
| Front yard | 3–4 ft | 0.91–1.22 m |
| Corner lot (sight triangle) | 3 ft or less near intersection | 0.91 m |
The 6-ft backyard standard is why 6 ft is the default privacy height — but “typical” isn’t “universal.” Some municipalities cap residential fences at 4 ft everywhere; others allow 7–8 ft with a variance. Corner lots face extra sight-line restrictions near intersections. Never rely on what neighbors built — their fence may predate current rules or may itself be non-compliant. More height questions are answered in the FAQ.
If you need height above the limit (a busy road, a two-story neighbor), ask about a variance process rather than building over and hoping. Variances take time but they’re cheaper than rebuilds.
HOA Rules: Stricter Than the City
Homeowner associations commonly regulate what the city doesn’t: permitted styles (some ban chain-link or require specific privacy styles), colors and stains, materials (wood-only or vinyl-only rules exist), which side faces out, and even maintenance standards after installation.
HOA architectural review can take 2–6 weeks. Get approval in writing before ordering materials — verbal “should be fine” from a board member isn’t approval. Keep the approval letter with your permit paperwork; contractors may ask for it too.
Setbacks, Easements, and Property Lines
- Setbacks: many jurisdictions require fences to sit a specified distance inside the property line (commonly 2–12 in / 5–30 cm; more in some areas). Build on the line only if local rules explicitly allow it.
- Utility easements: if a utility easement crosses your yard, you generally can fence across it — but the utility can tear out that section for access without compensation. Avoid placing gates or expensive sections over easements; check your plat for easement locations.
- Drainage easements: never block a swale or drainage path with a fence. Boards should allow water through at the bottom, and some jurisdictions prohibit solid fences across drainage easements entirely.
- Property lines: when the line is uncertain, a survey ($300–$600 typical) is cheap insurance against building on a neighbor’s land. A misplaced fence is the most expensive kind.
The Finished-Side Rule
Many cities and HOAs require the finished (smooth) side of the fence to face outward — toward neighbors and the street — with rails and posts on the owner’s side. This single rule shapes style choice: solid board and board-on-board fences have a clear “back,” while shadowbox looks finished from both sides and sidesteps the issue entirely. Check whether your jurisdiction has this rule before choosing a style; the material guide compares the styles.
Utility Locates and Digging Law
In the US, calling 811 before digging is free and legally required in most states. The locator marks public utilities (gas, electric, telecom, water/sewer mains) within a few business days. Note: private lines — sprinkler systems, landscape lighting, a gas line to a pool heater — are usually not marked; you’re responsible for knowing where those are.
Digging without a locate and hitting a line can bring fines plus full repair costs, which run into the thousands for fiber optic. There is no version of this step you can skip.
Neighbor Law Basics
- Notice: not legally required in most places for a fence entirely on your property, but informing neighbors prevents most disputes — especially about the finished side and construction noise.
- Shared fences: if a fence sits on the property line, many states treat it as shared, with costs splittable. Get cost-sharing agreements in writing before building.
- Spite fences: a fence built maliciously to annoy a neighbor can be actionable in some states. Build for privacy, not revenge.
- Existing fences: if you’re replacing a fence of uncertain ownership, establish whose it is (and whose land it’s on) before tearing it down.
Compliance Checklist
Clear these before ordering materials:
- ☐ Permit requirements checked with the local building authority (AHJ)
- ☐ Height limits confirmed for front, side, and back yards
- ☐ HOA architectural approval obtained in writing
- ☐ Property line verified (survey if uncertain)
- ☐ Easements identified on the plat; fence routed accordingly
- ☐ Finished-side rule checked; style chosen to comply
- ☐ 811 utility locate requested (and private lines identified)
- ☐ Neighbor notification done; shared-cost agreements in writing

Frequently Asked Questions
Do I need a permit for a 6-ft privacy fence?
Often yes — many jurisdictions require permits at or above 6 ft, and some for any fence. Check with your local building authority before buying materials; fees typically run $50–$200.
Can my HOA tell me what fence to build?
Yes, if you agreed to HOA covenants. HOAs commonly dictate style, color, material, and finished-side orientation — rules often stricter than the city’s. Get approval in writing.
How close to the property line can I build?
It depends on local setback rules — commonly 2–12 in (5–30 cm) inside the line, sometimes more. Verify locally, and get a survey if the line is uncertain.
Can I build a fence over a utility easement?
Usually yes, but the utility retains access rights and can remove the fence section without compensation. Avoid expensive sections and gates over easements.
Does the finished side have to face my neighbor?
In many jurisdictions and HOAs, yes. Shadowbox style looks finished from both sides and avoids the question. Check your local rule before choosing a style.

Compliance is the cheapest phase of a fence project and the most expensive to skip: a permit, a locate call, an HOA letter, and a verified property line cost little and prevent the nightmare scenario of modifying a finished fence. Clear the checklist above, then run your measurements through the Privacy Fence Calculator — build it right, build it legal, build it once.
Disclaimer: Calculator results are planning estimates based on the dimensions you enter; verify locally, as code, permit, and HOA requirements vary by jurisdiction and change over time. Always check with your local building authority (AHJ) and HOA, and consult a licensed professional for legal, structural, or code-related decisions.
