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

60Index Score / 100
#45 of 64 in Louisiana

St. Landry Parish, Louisiana requires a permit for construction, moving or adding a structure anywhere outside its incorporated towns, plus inside the city limits of Arnaudville, Palmetto and Melville12. The Parish Permits Office in the Opelousas courthouse issues that permit, and Parish Code Enforcement enforces zoning compliance parish-wide234. Septic systems go through the Louisiana Department of Health rather than a parish office, and the permits office directs applicants to call them before a building permit is issued56.

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

St. Landry Parish requires a permit for anyone outside its incorporated areas, and for anyone in the city limits of Arnaudville, Palmetto or Melville, who plans any construction, placement of a movable structure, moving, replacing, remodeling or adding a structure to a piece of property12. This covers new homes, additions, moved-in structures and accessory buildings such as barns and storage sheds, not just new houses2. Louisiana's State Uniform Construction Code governs the building-code side of that permit, and parishes like St. Landry administer the actual permit issuance and inspections1112. A qualifying farm structure on owned or leased agricultural land is exempt from enforcement of the specified part of that code, but a residence or structure attached to a residence is not a farm structure, and St. Landry Parish may still require a building permit before work begins13.

Who is the St. Landry Parish permits office, and how do you reach them?

The St. Landry Parish Permits Office is located in the parish courthouse at 118 South Court Street in Opelousas and can be reached at 337-948-36882. Before you can get a building permit you need a 911 address, which the parish assigns by phone at 337-948-90792. Parish Code Enforcement, reached at the same main number extension 1710, is the separate division that enforces zoning compliance, property-maintenance standards and condemnation of unsafe structures4. If your plans involve a culvert on a parish-maintained road, call 337-407-0950; if the road is a state highway instead, call 337-948-0253814.

Does St. Landry Parish have zoning?

St. Landry Parish has zoning, and Parish Code Enforcement is the division responsible for enforcing the parish's zoning compliance along with health, safety and property-maintenance ordinances34. Louisiana law authorizes the governing authority of most parishes, including St. Landry, to adopt zoning covering structure height, number of stories, structure size, lot occupancy, population density and the location and use of buildings and land; only Rapides, Jefferson, Sabine and Webster parishes are excluded from this general grant15. The specific district map, setbacks and use rules for a given parcel live in the parish's own zoning ordinance rather than in state law, so confirm the zoning district and its limits for your parcel with Code Enforcement before you buy4.

How do septic permits work in St. Landry Parish?

A septic system in St. Landry Parish is permitted by the Louisiana Department of Health, not the parish, and the parish's own Permits Office tells applicants to call the department at 337-948-0266 for the sewer and water facility requirements before a building permit is issued526. Louisiana's sanitary code bars installing, altering or operating an individual sewerage system without a permit from the state health officer, and a septic tank system may be used only where a community-type sewer system is not available1617. Final approval requires either an on-site inspection by the state health officer's representative or a completed Certification by Installer, which the licensed installer must submit within 15 days after the work is finished18. About 14.8% of St. Landry Parish's soils rate free of severe limits for a conventional septic drain field in the USDA soil survey, so many rural parcels will need a closer site evaluation before you can count on a standard system19.

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

St. Landry Parish's permit rule reaches 'placement of a movable structure,' which on its face covers an RV, park model or manufactured home brought onto a lot, so treat that kind of placement as something the Permits Office needs to know about rather than something you can do without contacting them21. Because the parish also enforces zoning, whether a movable structure can be used as a full-time residence, and for how long, depends on the zoning district that covers your specific parcel, which was not published in a form we could confirm for every district34. Call the Permits Office and Code Enforcement before you buy if living in an RV or tiny home while you build, or afterward, is part of your plan24.

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

  1. Call the Louisiana Department of Health at 337-948-0266 to learn the sewer and water facility requirements for your lot before you plan your site62.
  2. Get a 911 address for the property by calling 337-948-90792.
  3. If you are building new rather than moving in a structure, submit two copies of construction plans, including a site and floor plan, to the Permits Office and pay the inspection and review fee2.
  4. Once your plans are reviewed, return to the Permits Office at 118 South Court Street in Opelousas with your recorded deed, an estimate of construction cost, and, for new construction, your contractor's name and state license number2. A homeowner supervising construction of a personal residence may use the owner-builder exemption by filing the required affidavit and generally may not build more than one residence per year; the exemption does not waive health or life-safety requirements7.
  5. Apply for a culvert permit if your driveway needs one: 337-407-0950 for a parish road, or 337-948-0253 for a state highway8149.
  6. If FEMA's flood map places your lot in flood zone A/AE, plan for an elevation certificate, completed by a licensed surveyor or engineer, showing the lowest floor and equipment meet the required base flood elevation before final approval2.
  7. After the permit is issued, return your elevation certificate (if applicable) and the installer's certification for your septic system to the Permits Office before final electrical power will be connected2.

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

Ask the Permits Office whether the parcel sits in FEMA flood zone X or flood zone A/AE, since an A/AE property requires an elevation certificate and effectively requires flood insurance for a mortgage2. Budget for a septic site evaluation rather than assuming a standard drain field will work: only about 14.8% of the parish's soils rate free of severe limits for a conventional system in the USDA soil survey19. If you are buying into a small subdivision outside an incorporated area, Louisiana law can require a minimum lot area of 22,500 square feet and 125 feet of frontage, though whether that statutory exemption applies here depends on parish and population exclusions we could not fully confirm for St. Landry, so ask Code Enforcement directly10. Confirm whether your access road is parish-maintained or a state highway before you plan a driveway or culvert, since the permit contact differs either way814.

Watch-outs

  • St. Landry Parish's own Permits Office page lists two different suite numbers for the same courthouse address (Suite 118 in its contact block, Suite 133 in its FAQ text), so call 337-948-3688 to confirm the current suite before a visit2.
  • A septic permit from the Louisiana Department of Health, not the parish, must come before a building permit is issued in St. Landry Parish, so budget time for that step first52.
