Sherman and most corridor cities regulate residential fences with height limits (commonly 8 feet in back and side yards, lower in front yards) and permit requirements that vary by city; HOAs add their own approval. On unincorporated county land there is no fence permit. Utility locates apply everywhere.
More detail
Fence rules are the most local rules in construction, and they stack in three layers. City ordinances: Sherman regulates fence height and placement (the common Texas pattern: up to 8 feet in rear and side yards, substantially lower in front yards and at corner-lot sight triangles where drivers need to see), and permit practice varies across the corridor cities, some permitting all new fences, some only fences over a height threshold or in special districts, so the scope here confirms the current requirement with the specific city (Sherman's questions route through the same Development Services department as its building permits). Denison, McKinney, Anna, Celina, and Durant each hold their own versions of these rules. HOA and community layers: subdivisions and lake communities (Lake Kiowa's POA most prominently) add material, height, and approval requirements that are contractual rather than governmental, and skipping them invites expensive do-overs no city permit can save you from. County land: unincorporated Grayson, Cooke, Fannin, Bryan, and Marshall county land carries no fence permit at all, which covers most ranch fencing; the practical rules there are the property line itself (a survey beats a guess, and fences built a foot generous become the neighbor's problem to enjoy) and Texas's open-range nuances that make good perimeter fence a landowner's friend. Everywhere, one non-negotiable: 811 utility locates before augers touch dirt. The written scope names the layer that applies and carries any approvals inside it.
