How do you verify fence height compliance with code?

• A. Measure height by ground impact only.
• B. Estimate height by comparing to nearby fences.
• C. Check local height restrictions and measure from finished grade to top of fence.
• D. Base height on the gate height alone.

Answer: (C)

Verifying fence height compliance means first finding the local code's maximum allowed height for a fence in that area, then measuring from the finished grade to the top of the fence. Finished grade is the final ground surface after grading and landscaping, so this measurement reflects how tall the fence actually sits relative to the ground, even on sloped or uneven terrain.

This approach is best because it uses the jurisdiction’s specific rules and a measurement that matches the final ground conditions. If you measure from the ground surface at one point, or from an assumed level, you can misjudge the true height once the grade changes along the fence line. Estimating by comparing to nearby fences isn’t reliable because other fences may be in different zones or subject to different limits. Basing height on the gate alone ignores the overall fence height and any code requirements that apply to the entire fence line.

So, you confirm the allowed maximum height in the local code and measure vertically from the finished grade up to the top of the fence to ensure full compliance.
