St. Bernard Parish, Louisiana requires a building permit for new residential construction and administers parish zoning1,2. Individual sewerage systems require a Louisiana Department of Health permit before installation, alteration or operation3. Start with the parish Department of Community Development, and involve state health officials early if public sewer is unavailable4,5.
Do you need a building permit in St. Bernard Parish, Louisiana?
Yes.
Yes. St. Bernard Parish requires a building permit for new residential construction and elevation construction, and every building permit carries a $20 processing fee in addition to the applicable permit charge1,9. The parish administers building, electrical, mechanical and plumbing codes, although the available parish material does not identify every current code edition or permit exemption10.
A homeowner building without a licensed contractor must submit an affidavit claiming exemption from contractor licensure; the exemption does not remove the parish building-permit requirement1. Ask Safety & Permits which trade permits and plan documents apply before work begins4.

Does St. Bernard Parish have zoning?
Yes.
Yes. St. Bernard Parish administers zoning changes, compliance letters, conditional uses, variances and new subdivisions through its Planning & Zoning Division2. The parish address viewer includes zoning, future-land-use, flood-zone, parcel, overlay-district and piling-area layers, making it a useful first check before contacting Planning & Zoning6.
The published residential schedule includes single-family, two-family, multifamily, mobile-home and mobile-home-trailer-park districts, so similar-looking parcels can allow different uses12. Minimum lot sizes and setbacks vary by residential zoning district, and later amendments mean current numbers and exceptions should be confirmed from the enacted ordinance for the parcel12. We could not confirm one parishwide minimum dwelling size or lot-coverage number. Ask Planning & Zoning to check the parcel's district and overlays6.
How do septic permits work in St. Bernard Parish?
An individual sewerage system in St. Bernard Parish requires a permit from the Louisiana state health officer before installation, alteration or operation.
An individual sewerage system in St. Bernard Parish requires a permit from the Louisiana state health officer before installation, alteration or operation3. Louisiana Department of Health sanitarians in parish health units operate the local onsite-treatment permitting system13. A septic system may be used only where community sewer is unavailable and the applicable code requirements are met3.
Final approval requires verification that the installation complies with the sanitary code, through an onsite inspection, installer certification or both3. No mapped St. Bernard Parish soil is rated without severe limitations for a conventional septic drain field8. That rating does not by itself prohibit a system, but it makes early site evaluation and system planning especially important. Confirm sewer availability before assuming an onsite system is an option3.
Can you live in an RV or tiny home in St. Bernard Parish?
We could not confirm a general St. Bernard Parish rule allowing long-term RV occupancy on private land, temporary private-land camping or tiny-home occupancy.
We could not confirm a general St. Bernard Parish rule allowing long-term RV occupancy on private land, temporary private-land camping or tiny-home occupancy. Ask the Planning & Zoning Division whether the proposed use is allowed in the parcel's specific district and whether a conditional use, variance or other approval is needed6. The parish's residential schedule includes mobile-home districts, but that does not allow an RV or tiny home on every residential parcel12.
Manufactured homes have a defined parish process: submit the application, recorded titles, site plan, dimensions and wind-zone specifications before placement, then obtain required trade, flood-elevation, sewer or septic, and tie-down approvals before meter release13. A short-term rental also requires a parish application; rentals shorter than 30 consecutive days carry a $500 yearly fee and supporting-document requirements14.

- Use the parish address viewer, then ask Planning & Zoning to confirm the parcel's district, overlays, allowed residential use and dimensional rules6.
- Confirm public water and sewer availability; if community sewer is unavailable, contact the Louisiana Department of Health about onsite-system permitting and site review3,5.
- Ask the local building official for the parcel's flood zone and elevation standards; all new construction must meet standards set by its FEMA flood zone15.
- Create a customer-portal account to apply, pay and submit the materials required for the permit type4,10.
- Budget the valuation-based permit charge plus the $20 processing fee, then obtain applicable trade permits and inspections4,9.
- If access connects to a Louisiana state highway, obtain a signed and numbered state access permit before driveway construction16.
- Schedule electrical, plumbing, gas, mechanical and final building inspections with Community Development; the work must be approved before finals, and elevation construction receives a certificate of occupancy after all final inspections1,17.
What should you check before buying land in St. Bernard Parish?
Start with zoning, sewer service and flood exposure.
Start with zoning, sewer service and flood exposure. Planning & Zoning can confirm the parcel's district, district-specific lot size and setbacks, and whether a proposed subdivision or conditional use needs review6,12. Louisiana permits an individual sewerage system only when community sewer is unavailable and code requirements are met, while no mapped parish soil is rated without severe limitations for a conventional drain field3,8.
St. Bernard Parish says every parish property is vulnerable to flooding and directs parcel-specific flood-zone, base-elevation, floodway and drainage-history questions to the local building official15. For a manufactured home, septic approval or an inspected public-sewer hookup and an approved tie-down inspection are required before meter release; driveways and sidewalks must be installed by the tie-down inspection where required13. For a private well, Louisiana requires a licensed driller and state registration after completion; notification timing varies by well type7. A driveway onto a state highway needs a state access permit before construction16.
Watch-outs
- No mapped St. Bernard Parish soil is rated without severe limitations for a conventional septic drain field, so confirm sewer availability and onsite-system feasibility before buying3,8.
- St. Bernard Parish says every property in the parish is vulnerable to flooding; ask the local building official for parcel-specific flood-zone, elevation, floodway and drainage information15.
- Long-term RV occupancy, private-land camping and tiny-home occupancy were not confirmed; ask Planning & Zoning about the exact parcel and proposed use6.
