Fence Height rules, permits & costs

Fence rules are set locally and vary significantly. Height limits, permit thresholds, setback requirements, and HOA rules can all affect what you can build where.

Fence rules are local — here is what to check

Unlike most construction projects, fence rules are determined almost entirely at the local level. Your city or county has height limits, setback requirements, and permit thresholds that apply to your specific property. State rules provide a framework but rarely override local ordinances.

Front yard vs. back yard height limits

Most jurisdictions have different height limits for front yard and back yard fences. Front yard limits are commonly 3–4 feet (to maintain sight lines and neighborhood character). Back yard limits are commonly 6–8 feet. Corner lots are often treated differently and may have stricter height limits on both street-facing sides.

Pool fencing — non-negotiable rules

If you have a pool or spa, pool barrier requirements are strict and non-negotiable. Most states require a fence at least 4 feet high completely enclosing the pool area, with self-latching gates that cannot be easily opened by children. These requirements are life-safety rules and apply regardless of other local fence rules.

Property line disputes

Building a fence on or near a property line is one of the most common sources of neighbor disputes. A survey to confirm the exact property line before building is relatively cheap (typically $300–$1,500) and can prevent expensive disputes, removal orders, and legal costs.
