Newton County has no building, planning or zoning office: its courthouse at 101 S. Wood St., Neosho lists none, and the county posts no building code. Building permits come from the towns, led by Neosho’s Building Inspections Department and Joplin’s Building Division. On rural land the permit most projects need is the Newton County Health Department’s wastewater permit, required for every new, modified or repaired septic system regardless of lot size.

Septic systems: the Health Department, 812 W. Harmony St., Neosho (417-451-3743, option 1 for Environmental; open 8:00 a.m. to 4:30 p.m. weekdays), administers Wastewater Treatment Systems Ordinance 95-6, in force since September 1, 1995 and revised May 1, 1997. It reviews every system under 3,000 gallons a day, including single-family lagoons; larger commercial systems and lagoons serving two or more homes go to the Missouri Department of Natural Resources. A site evaluation by a registered soil scientist is required, because percolation tests are no longer accepted, and the application must carry the 911 address and legal description. The department reviews a complete application within 5 working days, makes a pre-site visit before issuing the permit number, and inspects the finished system on 24 hours’ notice before issuing the Permit to Use. Installers must be registered with the state and the county; a homeowner may install the system for the home he or she owns and lives in after showing the department the needed knowledge, with one homeowner permit per two years.
Floodplain: the state emergency agency lists the county Emergency Management office, 202 W. Brook St., Neosho (417-451-4357), as Newton County’s floodplain administrator. The county takes part in the National Flood Insurance Program with flood maps dated November 26, 2010, as do most towns; FEMA lists Cliff Village, Ritchey, Shoal Creek Estates and Stella as not participating.
