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

St. Landry Parish requires a permit before construction, placement, moving, replacement, remodeling or an addition outside incorporated municipalities; the parish office also serves Arnaudville, Palmetto and Melville1. The parish reviews plans, conducts required inspections and charges permit, plan-review and inspection fees910. Residential permit fees range from $250 to $1,550 by structure value, and a nonrefundable 8% parish administrative fee applies to plan review, inspections and related permits or affidavits10. St. Landry Parish must enforce the construction codes in the Louisiana State Uniform Construction Code framework; the absence of parishwide zoning does not remove building-code requirements112. A qualifying farm structure can be exempt from part of Louisiana's uniform construction code, but a residence or a structure attached to one is not a farm structure, and the parish may still require a permit12.

Who issues building permits in St. Landry Parish, and how do you reach the office?

The St. Landry Parish Permits Office is at 118 South Court Street in Opelousas and can be reached at 337-948-368813. The office handles residential and commercial applications, plan review and building-permit issuance14. Arnaudville, a town mainly in St. Martin Parish that reaches into St. Landry Parish, directs building-permit applicants to the parish office; the parish health unit approves proposed sewerage and sanitation facilities1516. Applicants also need a 911 address, available by calling 337-948-907913. St. Landry Parish Code Enforcement can be reached at the same main number, extension 1710, for zoning compliance, property-maintenance standards and unsafe-structure questions17. Required inspections are performed through a building-code enforcement officer or certified third-party provider18. For access work, call 337-407-0950 for a parish-road culvert permit or 337-948-0253 for a state-highway culvert permit6.

Does St. Landry Parish have zoning?

Unincorporated St. Landry Parish does not have parishwide zoning; the identified exceptions are selective I-49 areas and Mildred's subdivision2. Outside those limited areas, unincorporated St. Landry Parish has no parish zoning rules for minimum dwelling size, minimum lot size, setbacks, lot coverage, building height, RV occupancy, tiny-home occupancy, manufactured-home occupancy or temporary camping192. Incorporated municipalities may have their own zoning, so the unincorporated-parish answer does not carry into every town2. Parish Code Enforcement handles zoning-compliance questions as well as property-maintenance and unsafe-structure enforcement17. Before relying on the no-parishwide-zoning rule, ask Code Enforcement whether the parcel lies in an I-49 area, Mildred's subdivision or an incorporated municipality217. Building, sanitation, floodplain and access permits still apply independently of zoning432021.

How do septic permits work in St. Landry Parish?

Individual sewage systems in St. Landry Parish require approval from the state health officer, with the local parish health unit participating in installation and approval workflows3. The parish directs applicants to call the Louisiana Department of Health at 337-948-0266 for sewer and water requirements before the building-permit process is completed224. For commercial development in the parish permit office's jurisdiction, applicants must obtain an LDH sewer permit; the parish process says movable structures skip that step23. Where community sewerage is infeasible, an approved individual system may be used if it will not create a nuisance or public-health hazard8. Final electrical service requires the applicable health-department installer identification or certification24. Only about 14.8% of St. Landry Parish soils rate free of severe limitations for a conventional drain field, so obtain a site evaluation before assuming a standard system will work25.

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

For an RV or tiny home in St. Landry Parish, first establish whether the parcel is in an incorporated municipality, a selective I-49 zoned area or Mildred's subdivision; the absence of parishwide zoning does not establish the rules in those locations2. Placement of a movable structure still falls within the parish building-permit rule, so contact the Permits Office before bringing an RV, park model, manufactured home or movable tiny home onto the site1. St. Landry Parish must enforce Louisiana's uniform construction-code framework, so a tiny-home project must also be reviewed for applicable building-code requirements11. Full-time occupancy also needs lawful sanitation: an individual sewage system is allowed where community sewerage is infeasible only with state health approval and when it will not create a nuisance or public-health hazard8. Ask Code Enforcement to confirm the parcel's location before relying on the no-parishwide-zoning answer17.

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

  1. Ask Code Enforcement whether the parcel is unincorporated and outside the limited zoned areas217.
  2. Call the Louisiana Department of Health at 337-948-0266 for sewer and water requirements, and obtain the required sanitation approval223.
  3. Get a 911 address by calling 337-948-907913.
  4. For new construction, submit two plan copies with site and floor plans; pay review and inspection fees when submitting, then pay building-permit fees after approval26.
  5. Provide the contractor information required for new construction, or identify the work as self-contracted and accept responsibility for state and local compliance5.
  6. Obtain a culvert permit when needed from the parish-road or state-highway contact21.
  7. For an A/AE flood-zone site, have a licensed surveyor or engineer complete the elevation certificate before final approval7.
  8. Complete required inspections and return the applicable elevation, sanitation and address documents before final electrical service; projects that require a certificate of occupancy receive it through the parish closeout process182427.

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

Confirm whether the parcel is unincorporated, inside one of the limited zoned areas, or within a municipality before treating it as free of parishwide zoning2. Check the flood map early: in an A/AE zone, the lowest floor and service equipment must meet base-flood-elevation requirements, and a surveyor- or engineer-completed elevation certificate is due before final approval7. Budget for a septic site evaluation because only about 14.8% of parish soils rate free of severe limitations for a conventional drain field25. Confirm whether community sewer is feasible and obtain state health approval before choosing an individual system8. Identify whether access is from a parish road or state highway because the culvert contacts differ6. For a private well, Louisiana requires a licensed driller and post-installation registration, while domestic wells follow the state's post-installation notification route28.

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 visit13.
  • Starting covered work before St. Landry Parish issues the permit doubles the normal permit fee4.
  • No parishwide zoning does not waive building, sanitation, floodplain or culvert requirements2432021.
