A Trailer on Your Lot in Slidell and the Northshore
After Hurricane Isaias

A trailer on your own lot in St. Tammany and Washington parishes

Whether a trailer can stay on your lot is decided by your city, or by the parish outside city limits, and by your HOA if you have one. Here is what each one’s own code or official page says, in short. Our parent brand covers the residential RV rules for Northshore in detail.

• City of Slidell. An RV may be parked on a residential lot, but it may not be connected to utilities except for maintenance or for out-of-town visitors, and visitor hookups may not exceed 14 days a calendar year. No provision for living in an RV while the home is repaired was found, so ask Building Safety first. Source: Slidell Unified Development Code, Sec. 8.3 (off-street parking and loading)
• City of Mandeville. An RV parked on a developed site may not be used as living quarters, permanently or part time. The only exception is a temporary visitor to the people who live there, for up to 72 hours without a permit or up to two weeks with a temporary certificate of occupancy from the Building Inspector. No storm or rebuild exception was found, so ask Planning and Development first. Source: Mandeville Comprehensive Land Use Regulations Ordinance, Sec. 8.1
• City of Covington. No RV may be used for living, sleeping, or housekeeping in any zoning district unless it is in a regulated RV park. After a natural, federally declared disaster, the ordinance allows a manufactured home, not an RV, as temporary emergency housing for up to six months, not renewable. On August 11, 2026, the City Council adopted a resolution to consider waiving land use rules for the state expedited temporary housing program; the posted copy does not say whether the city opted in.

• Unincorporated St. Tammany Parish. The parish may issue a temporary permit for a manufactured home or RV used as a temporary residence while a home on the same site is built, repaired, or renovated. The permit runs up to six months, can be extended once by up to three months to finish the work, and the unit leaves within 30 days after the final occupancy permit for the home. Outside that permit, an RV on a developed home site may not be lived in. The section does not apply to temporary housing authorized under an emergency or disaster declaration, which the parish handles separately.

• City of Bogalusa (Washington Parish). One RV belonging to the owner of a single-family home may be parked on the owner's property only if it is not used as a dwelling, and mobile homes are not permitted in residential districts. No storm or rebuild exception for RVs was found, so ask the city before anyone moves in. Source: Bogalusa Code of Ordinances, Sec. 21-261

As of October 9, 2026, we found no Isaias emergency proclamation by Louisiana's Governor on the Governor's newsroom or GOHSEP's Isaias page, and no Isaias declaration by the parishes on this page. Louisiana law sets up a state expedited temporary housing program, run by GOHSEP, that can follow a presidential disaster declaration for parishes that have certified they will waive land use rules for an RV or other temporary housing next to the survivor's damaged home; it does not apply unless such a declaration is made.

Every size arrives furnished, with real beds, a full kitchen, a bathroom with a shower, and heat and air conditioning. More on a trailer on your property while you rebuild.

Power, water, and sewer for a trailer in St. Tammany and Washington parishes

Water, sewer or septic, and electrical connections are completed by licensed, insured contractors from our preferred vendor network, so you do not hire an electrician or a plumber. We look at how far the trailer will sit from the water, sewer, and power it will use, and confirm the site with you on the call before the trailer rolls.

Electric service in St. Tammany and Washington parishes comes from the utilities below. Each posts its own outage and storm updates.

• Cleco Power: a main provider in St. Tammany Parish, and serves a small part of Washington Parish
• Washington-St. Tammany Electric Cooperative: serves parts of Washington and St. Tammany parishes
• Entergy Louisiana: serves parts of St. Tammany and Washington parishes

Septic: In unincorporated St. Tammany Parish, an RV approved as a temporary residence must connect to potable water and sanitary sewer; where central water and sewer are available it must use them, not a private well, septic system, or holding tank, unless the director of environmental services approves, and every connection is inspected and approved before anyone moves in. Statewide, Louisiana's plumbing code requires a vented trailer trap in the building sewer below a travel trailer's drain outlet. Source: St. Tammany Parish Unified Development Code, Sec. 600-5

What we need to start

• The address where the trailer will sit
• When you need it, and who is moving in: your household, pets included, or the crew head count
• What the site has: a route in, firm ground close to level, and where the water, sewer or septic, and power are
• For a company: in the form, choose “I am arranging it for someone else,” then “Employer housing a crew” or “Contractor or restoration”
• Any approval the city, parish, or HOA has given, or the office you have been working with
