Tiny homes in Hattiesburg, Mississippi — zoning rules, THOW parking, builder costs, and what you need to know before buying.
Last researched April 2026
Hattiesburg is the Pine Belt's largest city and home to the University of Southern Mississippi and William Carey University, giving it a college-town energy on top of a steady medical, military (nearby Camp Shelby), and timber-industry base. The humid subtropical climate delivers warm springs, hot summers, pleasant falls, and mild winters with very little snow — comfortable outdoor living most of the year, though hurricane remnants and spring tornado risk are real. For tiny home buyers, Hattiesburg is one of the most practical Mississippi cities: a clearly written ADU ordinance, affordable land in Forrest and Lamar counties, and a builder scene that is growing alongside the region's general construction market.
Hattiesburg, Mississippi is one of the state's more ADU-friendly cities. As of April 2026, the city's Land Development Code — amended in recent years — permits accessory dwelling units as a conditional use in agricultural and residential zoning districts and in the B-1 and B-2 commercial zones. ADUs are capped at 900 square feet, must sit at least 10 feet behind the front building line of the primary home, and observe 5-foot rear and side setbacks. The city requires a site plan review to confirm neighborhood density impact before approval. Foundation-built tiny homes used as ADUs must comply with the Mississippi Building Code (IBC/IRC) and obtain building permits through the city. Tiny homes on wheels (THOWs) and park models built to ANSI A119.5 / RVIA standards are generally not accepted as permanent ADUs on city lots and are directed to licensed RV parks or campgrounds. Hattiesburg sits in Forrest County (with a portion in Lamar County), which follows its own county-level rules for unincorporated parcels. Contact the Hattiesburg Planning Department at (601) 545-4596 for current application materials, fees, and timelines. Verify current requirements with your local planning department before purchasing land or beginning construction.

Hattiesburg adopted an ADU-friendly amendment to its Land Development Code in recent years, and as of April 2026 accessory dwelling units are permitted as a conditional use in agricultural, residential, and B-1/B-2 commercial zoning districts. The maximum unit size is 900 square feet, the ADU must be located at least 10 feet behind the front building line of the primary dwelling, and setbacks are 5 feet from the rear and side property lines. A site plan review is required to evaluate density and neighborhood impact. Foundation-built ADUs must meet Mississippi Building Code (IRC) requirements and receive a building permit. Park models and THOWs (RVIA / ANSI A119.5) are not accepted as permanent ADUs on residential lots inside the city. Owner-occupancy, short-term-rental use, and utility connection rules can vary by district — contact the Hattiesburg Planning Department at (601) 545-4596 to confirm the full set of current ADU requirements for your specific parcel before starting design.
Communities, RV parks, and parking options in and near Hattiesburg.
THOW parking inside Hattiesburg city limits is generally directed to licensed RV parks rather than private residential lots. The Hattiesburg metro has several RV parks along I-59 and US-49 that offer monthly extended-stay rates with full hookups, including Paul B. Johnson State Park campground (seasonal/short-term) and private RV parks in the greater Forrest and Lamar county area. For longer-term siting, many Pine Belt residents look to rural parcels in Forrest, Lamar, Jones, or Perry counties where land-use rules are often more permissive than inside the city. Minimum-acreage requirements, manufactured-home anchoring rules, and septic/utility approvals still apply to any tiny home placed on rural land, and the Mississippi State Department of Health handles individual onsite wastewater permits. Unlike the Gulf Coast, Hattiesburg is roughly 75 miles inland, so ASCE 7 wind-zone requirements are less intense — but the region still sees hurricane-remnant winds and tornado risk, so anchoring and tie-down standards matter. Specific ordinance details for each surrounding county are not confirmed as of April 2026 — verify with the appropriate county planning office before purchasing land.

Pine Belt pricing tends to run lower than coastal Mississippi: roughly $45,000 for a basic THOW up to $140,000+ for a fully custom, foundation-built ADU. Rural Forrest and Lamar county land is relatively affordable, which helps keep total project costs down.
