Do you need a building permit in Caddo Parish, LA?
Unincorporated Caddo Parish, Louisiana requires a building permit for most construction and remodeling, including most electrical, plumbing and HVAC work; painting, flooring and listed code exemptions may not require one1. Projects inside Greenwood and Oil City must go directly to those towns for building permits1. The City of Shreveport's Division of Permits and Inspections issues parish building and trade permits2.
Permitted work may need one or several inspections, depending on the project and applicable code15. Outside city limits, each inspection on a building permit carries a $68.25 fee16. Caddo Parish Public Works also requires a development permit to build in the parish, and a structure built or moved onto land needs one when it is larger than 20 feet by 30 feet617. Building in a flood hazard area requires an elevation certificate6.
A homeowner may apply for a residential building permit, but registered and licensed contractors must perform all electrical, plumbing and HVAC work12. Residential work valued over $7,500 also requires a Louisiana Homeowner’s Exemption from Licensure12.
Caddo Parish construction under the Shreveport permit arrangement must meet the 2021 International Residential and Building Codes, the 2020 National Electrical Code, Louisiana amendments and local regulations18.
Who issues building permits in Caddo Parish, and how do you reach them?
The City of Shreveport Division of Permits and Inspections handles building, electrical, mechanical and plumbing permits for Caddo Parish2. The division is at 505 Travis St. Government Plaza, Suite 130, Shreveport, LA 71101, phone 318-673-61002. Apply, pay and request inspections through My Government Online2. Inside Shreveport, the city approves building plans and administers its own building permits; onsite sewage permitting remains with the Louisiana Department of Health through the Caddo Parish Health Unit1920. Permit applications generally need a site plan, construction plans, a statement of work and, when a contractor applies, a copy of the contract; approval waits until requested documents are attached21. Permits issue after the plans and specifications are reviewed and approved and payment is made21.
Permit fees vary with project scale, and starting work without a permit doubles the permit fee and can bring other penalties22. Caddo Parish Public Works' Permits Department at 318-226-6949 handles 911 addresses, culvert permits and right-of-way permits through online-only submissions23. Flood-zone questions go to Public Works at (318) 226-69346.
Commercial premises outside Shreveport city limits need a certificate of occupancy before use, even without construction; the permit guide excludes home businesses outside city limits from that requirement24.
Does Caddo Parish have zoning?
Yes, in part. The Caddo Parish Unified Development Code applies to land within the Caddo Parish Planning and Zoning Commission's planning area, and the Metropolitan Planning Commission keeps the official planning-area boundary38. Parish Public Works describes the MPC area as five miles outside Shreveport's city limits6. The Caddo Parish Planning and Zoning Commission, created by ordinance in 2022, hears planning and zoning matters in that area and makes recommendations to the Caddo Parish Commission7. Inside Shreveport, the city has its own zoning code; septic permitting stays with the Louisiana Department of Health through the Caddo Parish Health Unit2520.
For land beyond the planning area, we could not confirm what zoning applies; ask the Metropolitan Planning Commission (318.673.6480) whether your parcel is inside the planning limits before you buy7.
Inside the planning area, setbacks depend on the district: the front setback is 30 feet in R-A and R-E and 20 feet in R-1-12, R-1-10 and R-1-726. Within the parish planning area, zoning also decides where manufactured homes go: they may only be placed in districts the Use Matrix allows, and a district marked "E" needs a special exception approved by the Caddo Parish Planning and Zoning Commission8. Adding a second house is also regulated parishwide: a tract under five acres must be subdivided first, so call the Caddo permits department to see whether you have enough land11.
How do septic permits work in Caddo Parish?
Septic systems in Caddo Parish need a Louisiana Department of Health permit: no one may install, alter or operate an individual sewerage system without a permit from the state health officer427. Sanitarians in each parish health unit run that permit system; in Caddo Parish, that is the Caddo Parish Health Unit at 1035 Creswell Avenue, Shreveport, (318) 676-5222285.
Louisiana allows a septic system only where community sewer is not available, and the state must decide that a sewer connection is not feasible before issuing a permit299. A mechanical treatment plant is allowed only when a conventional system would not work30. That matters here: only 13.6% of Caddo Parish's soils avoid NRCS's "very limited" rating for a conventional drain field, so expect a careful site review and possibly an individual mechanical treatment plant3130. Final approval comes after an inspection or the licensed installer's certification, which is due within 15 days of completion32. Caddo Parish also requires health-unit approval for soil absorption and spray irrigation systems4.
Can you live in an RV or tiny home on your land in Caddo Parish?
Not in an RV, inside the planning area: the Caddo Parish Unified Development Code says no recreational vehicle may be used for living, sleeping or housekeeping in any district, or be hooked up to public utilities103. For land outside the planning area, we could not confirm the rule, so ask the Metropolitan Planning Commission and Caddo Parish Public Works before buying land to live on in an RV717.
A tiny home built as a real dwelling needs the same permits as any house, including the Shreveport building permit and the parish development permit26. Within the parish planning area, the UDC allows no more than one accessory dwelling unit per lot; a detached ADU can be a prefabricated or shipping-container structure if it meets the International Residential Code, and it cannot exceed 60% of the main house's floor area or 1,800 square feet, whichever is less8. On a tract under five acres, a second residence also means subdividing11.
Within the parish planning area, a manufactured home placed outside a park must sit on a concrete slab or runway and meet the code's design standards8.
Building a home in Caddo Parish: what are the steps, in order?
- Ask the Metropolitan Planning Commission whether the parcel is inside the planning area and what its zoning is78.
- Check the flood zone with Caddo Parish Public Works at (318) 226-6934; get an elevation certificate if the site is in a flood hazard area6.
- Get a 911 address and any culvert or right-of-way permit for the driveway from the Public Works Permits Department, online only; the building-permit guide also lists driveways among projects that need a permit with a site plan2333.
- Without community sewer, apply for a septic permit at the Caddo Parish Health Unit59.
- Submit the site plan, construction plans, statement of work and any required contract copy with the building-permit application through My Government Online212.
- Pay the variable permit fee after the plans and specifications are approved; do not begin early, because the fee doubles when work starts without a permit2122.
- Schedule every required inspection through the same system152.
- Ask the Division of Permits and Inspections what occupancy approval your home requires; the published commercial certificate requirement does not establish the residential rule224.
What should you check before you buy land in Caddo Parish, Louisiana?
Flooding: Caddo Parish Public Works says flooding can occur anywhere in the parish, and it will check whether a parcel outside the MPC area is in a flood zone6. Because the parish is in the National Flood Insurance Program, unincorporated residents can buy rate-restricted flood insurance6. Development in a regulatory floodway needs a no-rise certification before a permit can issue34.
Soils and sewer: with only 13.6% of soils avoiding the NRCS “very limited” rating for conventional drain fields, ask the Caddo Parish Health Unit about the lot before you close315.
Zoning and lot size: confirm whether the land is in the planning area, and remember that a second house on under five acres requires subdividing711.
Costs and climate: farmland averages about $4,525 an acre and typical homes about $153,0003536. Property taxes are low, about 0.6% effective, a median of $1,081 a year1314. Caddo Parish gets about 52 inches of rain a year yet was in severe drought in 17.7% of years, and mid-century projections show about 28 days a year at or above 100°F373839. The parish is about 65% wooded and nearly flat, with 99.2% of land at 15% slope or less4041.
Watch-outs
- Caddo Parish permits run through two governments: Shreveport issues and inspects the building permit, while the parish reviews every permit for its 911 address and floodplain status422.
- A parish development permit is required to build in Caddo Parish, including for structures larger than 20 by 30 feet that are moved onto a lot617.
- Living in an RV is prohibited in every zoning district inside the Caddo Parish planning area, and an RV there may not be hooked up to public utilities103.
- Putting a second house on a Caddo Parish tract under five acres requires subdividing first11.
- A homeowner may pull a residential building permit, but licensed contractors must perform the electrical, plumbing and HVAC work, and work over $7,500 requires a Louisiana Homeowner’s Exemption from Licensure12.
