VERY HIGH building freedom in practice. Least-populous parish in Louisiana (4,147); LSUCC applies by state law but no parish residential building-permit office could be confirmed. Governance is via the Police Jury (no dedicated permitting website; parish uses the state louisiana.gov listing and Facebook). Residential code enforcement appears absent → b8. [Actual enforcement UNVERIFIED.]

No county's freedom erases state law: septic/wastewater permitting (health authority), well permits and water rights (state engineer/DNR), floodplain rules with federally connected financing, and — in some states — state-run electrical inspections. The full card details which of these bite in Tensas Parish and how hard.
The score describes unincorporated county land only. Inside Tensas Parish, incorporated municipalities set their own, usually stricter, rules — including: St. Joseph, Newellton, Waterproof. Land inside town limits follows town code.
