Do you need a building permit in Washington Parish, Louisiana?

Yes. Unincorporated Washington Parish requires a permit before covered construction, reconstruction or development, including building, major remodeling, manufactured-home placement and flood repair.1 Louisiana's uniform construction code also requires enforcement for new residential construction, reconstruction, qualifying additions and extensive alterations.10 Qualifying agricultural structures are exempt from the parish permit fee, but the fee exemption does not establish an exemption from permits or construction codes.11 A homeowner may use Louisiana's owner-builder exemption for a personal residence by providing the state board's affidavit when obtaining the permit; licensable subcontractors and health and life-safety rules remain covered.8

Who issues building permits in Washington Parish, and how do you apply?

The Washington Parish Building and Permitting Department issues development permits from 203 11th Avenue in Franklinton and can be reached at 985-839-5456.12 The parish provides MyGovernmentOnline for online permit applications.12 Call before submitting to confirm the current application documents and fee for the project.1213 Permitted homes move through inspections that can include base-flood elevation where applicable, pre-pour plumbing, footings and foundation, brick, rough-in mechanical, electrical, plumbing and framing work, insulation and a final inspection.14 Approved plans must remain at the job site for inspections, subject to the parish's listed exceptions.14

Does Washington Parish have zoning?

Washington Parish has a development ordinance that applies throughout its unincorporated area and is administered by the Permit Office.2 A dwelling, counting heated and unheated areas under roof, must stand at least 30 feet from every property line.3 New subdivision lots using individual sewerage treatment must contain at least 1 acre per single-family living unit and provide 140 feet of road frontage, although cul-de-sac frontage may be 75 feet.4 Lots served by approved community sewerage and water also require at least 1 acre, with 100 feet of frontage or 75 feet on a cul-de-sac.4 A complete zoning-district map, minimum dwelling size, general height limit and lot-coverage rule could not be confirmed; ask the Planning Commission about the particular parcel.15

How do septic permits work in Washington Parish?

A new single-family building-permit application in unincorporated Washington Parish must include a Health Unit sanitation letter, and the onsite system needs Parish Health Department approval under the Louisiana Sanitary Code.5 Start with the Washington Parish Health Unit's environmental-health office at 120 11th Street in Franklinton, 985-839-5646.16 Louisiana requires state-health-officer approval of plans and specifications before an individual sewerage system is installed, altered or operated.17 A conventional septic system is available only where community sewer is unavailable and the site meets the code.18 Only 20.7% of parish soils are rated without severe limits for a conventional drain field, so make septic feasibility an early purchase contingency.19 Final verification may use a state representative's site inspection, an installer certification or both.20

Can you live in an RV or tiny home in Washington Parish?

In an approved Washington Parish RV park, the ordinance defines temporary camping as 1 month or less.6 Occupancy beyond 3 months in any 12-month period is treated as permanent and prohibited, subject to the stated exception for qualifying transient workers.7 An RV park must connect to public sewer when it is available within 300 feet; otherwise the park needs an approved private sewerage facility, and every park needs potable water.21 These RV-park rules do not answer whether an owner may occupy an RV on an ordinary private parcel, so ask Planning and Building before moving in or connecting utilities.61512 A specific tiny-home occupancy rule and general minimum dwelling size could not be confirmed; a tiny home used as a dwelling remains subject to the applicable permit and construction-code rules.110

What are the steps to build a home in Washington Parish?

  1. Ask the Planning Commission how the parish development ordinance and any subdivision conditions apply to the parcel.215
  1. Confirm that the planned dwelling clears the 30-foot property-line setback and that a newly divided lot meets the applicable acreage and frontage rules.34
  1. Confirm flood status before design; an AE Floodway does not allow new construction, substantial improvements or fill under the parish rule.22
  1. Contact the Health Unit for the sanitation letter and onsite-system approval required for the residential permit package.516
  1. Submit the building application through the parish permit office and confirm the project-specific fee.1213
  1. Schedule the required inspections and keep approved plans at the job site.14

What should you check before buying land in Washington Parish?

Put flood status, septic feasibility and legal access ahead of the house plan. Washington Parish prohibits new construction, substantial improvements and fill in an AE Floodway, while only 20.7% of parish soils are rated without severe limitations for conventional drain fields.2219 If a tract will be divided, major subdivisions require preliminary and final review and Planning Commission approval, while qualifying minor subdivisions use an abbreviated process.23 If access will connect to a Louisiana state highway, the state driveway permit must be signed and numbered before construction begins.24 New water wells require a licensed driller and state registration within 30 days after completion; domestic wells use the post-installation notification route.9 The effective property-tax rate is about 0.4%, with a median annual bill near $488.2526

Watch-outs

  • An AE Floodway site does not allow new construction, substantial improvements or fill under Washington Parish's floodplain rule.22
  • The parish's agricultural-structure provision waives qualifying permit fees; it does not confirm an exemption from permits or construction codes.11
  • A dwelling must remain at least 30 feet from every property line, including both heated and unheated areas under roof.3
  • Washington Parish's RV-park camping and occupancy limits do not answer whether an RV may be occupied on an ordinary private parcel; ask Planning and Building before relying on an RV during construction.671512
