Tangipahoa Parish, Louisiana requires a building permit through the Parish Permit Office before any structure is built1. Whether unincorporated parish land is divided into zoning districts could not be confirmed, so ask the Planning Department about parcel-specific land-use rules23. Septic systems require state approval, and the parish permit process requires sewer approval through Environmental Health45.

Do you need a building permit in Tangipahoa Parish, Louisiana?
Yes. The Tangipahoa Parish Permit Office requires a building permit before any structure is built, and electrical, mechanical and plumbing subcontractors must obtain permits for new construction1. Louisiana requires parishes and municipalities to administer permits for construction covered by the State Uniform Construction Code15. Tangipahoa Parish charges residential new-construction building permits at $0.15 per square foot, rounded to the nearest dollar; residential electrical, mechanical and plumbing permits are each $0.10 per square foot16. The complete inspection sequence for a particular project could not be confirmed, so ask the Permit Office which inspections the plans will require17.
Who issues building permits in Tangipahoa Parish, and how do you reach them?
The Permit Office runs two locations: the main Hammond office at 15485 West Club Deluxe Road, Hammond, LA 70403, phone (985) 542-2117, and a second office at 113 North Bay St., Amite, LA 70422, phone (985) 748-202417. The published process starts with a property address, survey or deed, building plans, flood determination and plan review18. Environmental Health then handles sewer approval, while parcels on the Tangipahoa Parish Sewer District must contact that district5. Once sewer approval is ready, return to the Permit Office to pull the building permit18. Land-use, subdivision and base-flood-elevation questions go to the Planning Department at 15485 West Club Deluxe Road, Hammond, LA 70403, phone (985) 340-90283.
Does Tangipahoa Parish have zoning, and what does that mean for RVs, tiny homes and setbacks?
Whether unincorporated Tangipahoa Parish is divided into enforceable zoning districts could not be confirmed2. The Tangipahoa Parish Planning Department addresses land-use situations and verifies compliance with the Subdivision Regulations and Comprehensive Land Use Plan8. Louisiana law authorizes parish zoning districts, but that authority alone does not prove that a zoning map or district rule applies to a particular parcel19. Setbacks, lot coverage, building height and minimum dwelling size need a parcel-specific answer from the Planning Department and, inside a municipality, the relevant municipal office20212223. Tangipahoa Parish is expressly excluded from the state provision that limits planning-commission review for certain single-owner subdivisions, so do not use that provision's lot-size threshold as a shortcut around parish subdivision review9.
How do septic permits work in Tangipahoa Parish?
Septic systems in Tangipahoa Parish are permitted under Louisiana's statewide Sanitary Code, which puts permitting authority with the state health officer rather than a parish office424. In practice, the Permit Office routes you to Environmental Health for sewer approval: submit your survey or deed there, then bring the approval back to the Permit Office before your building permit is issued6. Statewide, no one may install, alter, or operate an individual sewerage system without first obtaining a permit, and a septic tank system is only allowed where a community-type sewerage system is not available2526. Once installed, final approval requires either an on-site inspection by the state health officer's representative or a completed Certification by Installer, submitted within 15 days of completion27. Soils make this a real planning issue: only about 14.7% of Tangipahoa Parish's soils are free of severe limitations for a conventional septic drain field, so expect the state's site evaluation to shape where and how you can build12. If you want to install or maintain your own mechanical treatment plant at your own primary residence rather than hiring a licensed installer, Louisiana allows it under a homeowner certification process, and the regional coordinator for Tangipahoa Parish is reachable at 985-871-1332, though you'll need to pass a training workshop with a 70% grade every five years28.
Can you live in an RV or tiny home on your land in Tangipahoa Parish?
Tangipahoa Parish's rules for living in an RV or occupying a tiny home on private land could not be confirmed, so ask the Planning Department before buying land or placing a unit23. Louisiana's temporary-stay limits for state parks do not answer whether someone may live in an RV on private land29. A tiny home built as a residence still faces the parish building-permit process1. Any individual sewerage system serving an RV or tiny home must receive a state permit before installation, alteration or operation, and a septic tank system is allowed only where a community-type sewerage system is unavailable2526. Ask Environmental Health what wastewater arrangement it will approve before treating an RV or tiny home as a buildable plan5.
Building a home in Tangipahoa Parish: the steps, in order
- Get a property address, then take the survey or deed and building plans to the Permit Office for flood determination and plan review18.
- Submit the survey or deed to Environmental Health for sewer approval; only about 14.7% of parish soils lack severe limits for a conventional drain field, so settle septic feasibility early512.
- If the site is in a special flood hazard area, obtain Community Development approval before the building permit10.
- Return with the completed application, plans, sewer approval, survey or deed, permit fee and any required stormwater permit18.
- If acting as the contractor for your own residence, bring a notarized homeowner affidavit7.
- Obtain a parish permit before placing a new or replacement driveway culvert in a parish roadside ditch; a state-highway connection instead requires LaDOTD approval3031.
- Register subcontractors and obtain their trade permits for new construction1.
What to check before you buy land in Tangipahoa Parish
Start with septic feasibility: only about 14.7% of Tangipahoa Parish soils lack severe limitations for a conventional drain field, so obtain state approval before committing to a house location1225. Ask the Planning Department about subdivision and land-use restrictions on the exact parcel because current zoning districts could not be confirmed283. Check flood status early: the parish performs a flood determination during permitting, and Community Development administers the parish flood-prevention ordinance1011. Confirm whether access crosses parish or state right-of-way, because parish roadside-ditch culverts and state-highway connections follow different permit paths3031. A new Louisiana water well generally must be installed by a licensed driller and registered after completion; domestic wells follow post-installation notification rules rather than the ordinary advance-notification process32. The effective property-tax rate is about 0.4%, with a median annual bill near $8871314.
Watch-outs
- No official source confirms unincorporated Tangipahoa Parish has an enforceable zoning ordinance; don't assume a parcel is unrestricted, and confirm land-use rules with the Planning Department before you buy or build23.
- Tangipahoa Parish regulates land subdivision within its planning jurisdiction and is excluded from the state exemption for certain single-owner subdivisions, so ask the Planning Department to review any proposed land division89.
- Only about 14.7% of Tangipahoa Parish's soils are free of severe limitations for a conventional septic drain field, so budget for a site evaluation and the possibility of a mechanical treatment plant or other alternative system12.
