Here's what most contractor pages get wrong. Fence-height rules do vary across the metroplex, but the surprise is the opposite of what you'd expect: a standard 8-foot backyard privacy fence is allowed by right in Dallas and every major suburb we serve. The real differences are the front-yard limits and the fact that nearly every city requires a permit — miss that and you're looking at a red-tag.
City of Dallas. Back and side yard fences can go up to 9 feet, but a permit is required for anything over 6 feet. That means a standard 8-foot privacy fence needs a permit in Dallas. Front-yard fences top out at 4 feet, and anything over 4 feet in the front also needs a permit. Go past 9 feet and it's legally a "structure" that requires an engineer and a special exception, which almost nobody does.
Plano. Allows up to 8 feet in the rear and side yards. Front-yard fences are limited to 40 inches and must be at least 50% open. A permit is required for every new fence, and for replacements beyond minor repairs.
Richardson. Also allows up to 8 feet in the rear and side yards. Front-yard fences are held to 3 feet, have to be decorative, and need Building Official sign-off. A permit is required for any fence 2.5 feet or taller.
Allen. Up to 8 feet in the rear and side yards. Allen effectively keeps fences out of the front yard — only low walls under 36 inches tied to a porch or patio — and requires a permit.
Frisco. Up to 8 feet in the rear and side yards and 4 feet in the front, with a permit required for every new fence (small repairs of a section or two are the only exception).
McKinney. Up to 8½ feet in the rear and side yards — the most generous around — with front-yard fences limited to 4 feet and at least 50% see-through, and a permit for every new fence.
The real pattern: an 8-foot backyard privacy fence is on the table in Dallas and across these suburbs — the catch is the front yard and the permit. Front-yard limits run from Dallas's 4 feet down to Richardson's 3 feet and Plano's 40 inches, and nearly every city requires a permit for a new fence. We know each city's counter, we pull the permit, and we build to code so your fence passes inspection the first time. See what we do across Plano, Frisco, Richardson, and Allen.
One more layer: your HOA can be stricter than the city. Many Dallas-area associations dictate the finished ("good-neighbor") side must face the street, cap the height below what the city allows, and publish an approved stain-color list. City approval and HOA approval are two separate hurdles. We handle both.
