Building permits, zoning and septic rules in St. Helena Parish, Louisiana

#26 of 64 in Louisiana

Unincorporated St. Helena Parish, Louisiana requires a permit before you construct, enlarge, alter, move, demolish or change the use of a building, issued through the parish's own Building Department12. The Police Jury holds the legal authority to zone but hasn't adopted a parish-wide zoning ordinance, so there's no zoning-based minimum lot size, setback or land-use restriction on unincorporated land right now34. Septic systems still need a state permit, applied for through the parish's Environmental Health office rather than the Building Department56. Louisiana also lets a homeowner install and maintain their own septic system under a state homeowner-certification program7.

Do you need a building permit in St. Helena Parish, Louisiana?

St. Helena Parish requires a permit before you construct, enlarge, alter, repair, move, demolish or change the occupancy of a building, or before you install or alter its electrical, gas, mechanical or plumbing systems12. The parish lays this out as a 6-step process running from your 911 address through plan review, the permit application, the permits themselves, environmental-health sign-off and a final utility-connection form2. Commercial structures carry an extra requirement: State Fire Marshal approval before the parish will even begin the permitting process2. Skip the process and you won't get permanent electricity, since the parish withholds that until every inspection and environmental confirmation is in hand2.

Who is the St. Helena Parish building department, and how do you reach them?

The St. Helena Parish Police Jury Building Department issues building, electrical, gas, mechanical and plumbing permits for the parish, including unincorporated land2. Reach the department at (225) 222-4549; its office is in the Police Jury building at 17911 Highway 43 in Greensburg2. That's also where you bring your two sets of plans, your site plan and your legal description and survey when you file2.

Does St. Helena Parish have zoning?

St. Helena Parish has not adopted a parish-wide zoning ordinance, even though our research found that the Police Jury holds statutory zoning authority it simply hasn't exercised3. Louisiana's general parish zoning grant covers every parish except Rapides, Jefferson, Sabine and Webster, so St. Helena is legally free to adopt zoning whenever its Police Jury chooses to8. For now, because there's no zoning ordinance on the books, unincorporated St. Helena Parish sets no zoning-based minimum lot size, setback, building-height limit or restriction on RVs, tiny homes, manufactured homes or accessory dwellings on your own land4. Ask the Police Jury directly if you're planning something long-term, since this is one of the parish rules most likely to change2.

How do septic permits work in St. Helena Parish?

Louisiana's Sanitary Code puts septic permitting in state hands, not the parish's: no one may install or alter an individual sewage system without a permit from the state health officer, applied for through the St. Helena Parish Environmental Health office56. Before a site evaluation, you'll need the landowner's contact information, proof of ownership, a property survey, your 911 address, your proposed use of the property (bedroom count for a house or mobile home, employee count for a business) and your water-service type62. The permit itself runs through the state's two-stage process, with a final permit issued only after an inspection or licensed-installer certification filed within 15 days of completion910. Louisiana also lets a homeowner install and maintain their own septic system under a state homeowner-certification program, an option worth asking the Environmental Health office about directly7. Only about 23% of St. Helena Parish soil carries no severe limitations for a standard drain field, so budget for a site evaluation before assuming a basic system will work11.

Can you live in an RV or tiny home on your land in St. Helena Parish?

With no zoning ordinance on the books, St. Helena Parish sets no rule against living in an RV, a tiny home or a manufactured home on your own unincorporated land4. You'll still need the Building Department's permit for any permanent structure or utility hookup, and the state's septic permit if you're adding sewage service25. Because the Police Jury holds the legal power to zone even though it hasn't used it, this unrestricted status isn't guaranteed forever; check with the Building Department before making long-term plans around it3.

Building a home in St. Helena Parish: the steps, in order

  1. Obtain your 911 address from the 911 office in the Police Jury building at 17911 Highway 43, Greensburg; the Environmental Health department won't process your sewer application without one2.
  2. Bring two sets of plans and a site plan to the Building Department for plan review, and pay the plan-review fee at that time2.
  3. File your building permit application with a legal description and survey of the property, a site plan showing where the home will sit, and payment for the fees2.
  4. Obtain your building, sewer and flood-elevation-certificate permits from the Building Department once plan review is complete2.
  5. Satisfy the Environmental Health office's sewer-permit requirements: a property survey, a deed, and copies of your sewer and building permits, following the state's individual-sewage-system permitting process65.
  6. Submit the utility connection form; the parish won't release permanent electricity until every inspection is approved and the environmental confirmation form is in, and a certificate of occupancy follows once all requirements are met2.

What to check before you buy land in St. Helena Parish

St. Helena Parish is heavily wooded, at roughly 78% forest cover, and essentially flat, with all of its land at 15% slope or less, so tree clearing is a more likely site-prep cost than grading1213. Population density is light at about 26 people per square mile, and the nearest metro area is roughly 34 miles away1415. The effective property tax rate runs about 0.4%, with a median annual bill near $4481617. Because there's no zoning ordinance today, deed restrictions and subdivision covenants — not the parish — are what will actually limit what you can do with a given tract, so read them before you buy4.

Watch-outs

  • St. Helena Parish's zoning status is a matter of choice, not law: the Police Jury has the authority to adopt zoning and simply hasn't, so confirm current status with the Building Department rather than assuming it will stay this way3.
  • Any commercial structure needs State Fire Marshal approval before the parish's own permitting process even starts; budget time for that step if you're building anything other than a private home2.
