Splitting Land or Opening an RV Park in Harrison County
A Harrison County plan for new lots, RV pads, or a tiny-home park needs road and wastewater review together. Environmental Health is at 2005 Warren Drive. The county requires access wide and strong enough for its largest EMS vehicle to reach the sites.
The state septic permit exemption starts at ten acres or more, not less than ten. It covers only one single-family home. All system parts must be at least 100 feet from property lines. Effluent must stay on the land. A qualified site review is required, and the system must not cause a nuisance or pollution. Local rules may be stricter, and construction standards still apply.
That narrow exemption is not permission for an RV park or multiple homes. The owner-install rule is separate. It lets some owners put in their own system without an installer license; it does not waive a needed permit. Confirm the county permits and design requirements with Environmental Health at 903-935-4870 before advertising lots or placing homes.
