Pearl River County, Mississippi Building Permit Guide

Pearl River County is one of the five coastal counties that cannot opt out of building-code enforcement — even though it lies inland from the Gulf shoreline — at about 59,000 residents. Anchored by Poplarville, the county seat, and Picayune, its largest city, it enforces the hurricane wind and flood provisions the coastal mandate requires through the county Planning & Building Department.

This guide covers the coastal mandate as it applies to an inland coastal county, the wind and flood requirements, unincorporated permitting, and where city-limit work goes instead.

This guide covers unincorporated Pearl River County. Picayune and Poplarville run their own building programmes. Part of the City of Lumberton, which lies mostly in Lamar County, is also in Pearl River County; for a parcel there, confirm with the Planning & Building Department whether the city or the county issues the permit.

What requires a building permit in Pearl River County?

Mississippi is a local-option state: the Mississippi Building Codes Council designates recent editions of the International Codes as statewide minimum codes, and under Senate Bill 2378 of 2014 counties and municipalities must adopt them unless they opted out before 30 November 2014 (Mississippi Code §17-2-4; the five coastal counties have separate wind and flood requirements under §17-2-1). So the first question on any project here is not what the code says — it is whether the county enforces a building code at all, and what it requires where it does.

Where a jurisdiction enforces the code, exemptions are narrow and local, and an exemption from a building permit is never an exemption from zoning, setbacks, floodplain rules, utility approval or a fire review. Confirm scope with the county before work starts rather than after.

Which code applies — and whether one applies

As one of the five coastal counties that cannot opt out under 2006 House Bill 1406, Pearl River County enforces the code with hurricane wind and flood-mitigation amendments — even though it lies inland from the shoreline rather than on the Gulf. High design wind speeds and flood provisions apply here; Marine Resources wetland permitting, by contrast, covers the coastal zone of Hancock, Harrison and Jackson counties and does not reach Pearl River.

Some work is exempt statewide: farm structures once the owner files an affidavit (Mississippi Code §17-2-7), and manufactured housing built to federal standards, certain industrial and utility facilities, buildings on non-public fairgrounds and hunting or fishing camps with an owner’s affidavit (§17-2-9). None of these exemptions reaches floodplain rules. The state minimum codes are the Mississippi Building Code and Mississippi Residential Code, the residential code drawn from the 2021 International Residential Code.

Who handles permitting in Pearl River County?

The county Planning & Building Department — its Planning and Development, Building, and Floodplain Management divisions — permits and inspects structures in unincorporated areas under the 2018 International Building and Residential Codes, with offices in Poplarville and Picayune and applications through the MGO Connect portal. Picayune and Poplarville run their own departments.

Because Pearl River County cannot opt out, the wind and flood requirements apply on unincorporated parcels the way they do closer to the coast — design wind speed, engineered connections and flood elevation shape the structure ahead of design. Confirm the jurisdiction from the parcel first, since Picayune and Poplarville run their own departments.

The county also enforces its Flood Damage Prevention Ordinance, and it has warned vendors that portable buildings, sheds, steel barns, cabins and similar structures sold as tiny homes or barndominiums must meet the 2018 IRC and its wind requirements, and be approved under a development permit and a building permit, before anyone lives in them.

In 2025, building permits issued in unincorporated Pearl River County authorized 348 new privately owned housing units, all of them single-family homes, according to the U.S. Census Bureau Building Permits Survey.

Permit types

Residential permits

Residential work is shaped by wind and flood first even inland: engineered connections, opening protection where required and flood detailing on low-lying parcels. Re-roofs and solar need permits, and state licensing starts above $50,000 for a new home but above $10,000 for a remodel or re-roof — the coastal permit and inspection still apply.

Commercial permits

Commercial work runs through plan review with wind and flood engineering; the department coordinates the review of commercial site plans and subdivisions for approval by the Board of Supervisors, and work of $50,000 or more crosses the MSBOC commercial threshold.

Mississippi licenses contractors through the Mississippi State Board of Contractors: a commercial certificate of responsibility for commercial and public work of $50,000 or more, a residential builder licence for a new home costing more than $50,000, and a residential remodeling licence for improvements to an existing home costing more than $10,000. Below those amounts Pearl River County’s own permit, inspection and registration rules still apply where it enforces the code. Contractor licensing in Mississippi

Pearl River County permit costs and fees

Budget the county permit and plan-review fees, separate trade permits, and wind and flood engineering and elevation costs. There is no separate state permit fee.

Fee schedules in Mississippi are set locally and revised on each jurisdiction’s own cycle, so ask Pearl River County for the schedule in force on your filing date, and ask separately about plan review, trade, re-inspection and revision charges. How Mississippi permit fees work

Trade permits and who may pull them

Trade permits are generally separate from the building permit and are issued to the licensed installer where a jurisdiction enforces the code. State licensing through the Mississippi State Board of Contractors starts at $50,000 on commercial work and above $10,000 on residential remodeling, and the Board states that residential electrical, plumbing or HVAC work under $10,000 needs no state licence; a jurisdiction may add its own registration, so the credential check depends on both the project value and the jurisdiction. Confirm each before filing rather than after the first correction notice.

Electrical, plumbing and mechanical contractors hold MSBOC classifications on commercial work of $50,000 or more. A jurisdiction that enforces the code may also require local trade registration regardless of project value, while some that have opted out require no local trade permit, so confirm before assuming either way.

How to apply for a Pearl River County building permit

In Mississippi, correction cycles turn mostly on the local layer: which code edition Pearl River County enforces, whether a coastal or flood-zone parcel triggers wind and elevation requirements, whether the project value crosses a state licensing threshold, and whether the submittal has the sets and forms the office requires. Permits also carry a validity period set by the issuing jurisdiction, so confirm the expiry on phased or delayed work. Review and corrections in Mississippi

Inspections in Pearl River County

Where the jurisdiction enforces the code, standard checkpoints include footing and foundation, framing, rough-in trades, insulation and energy, fire systems on commercial work, and final, with occupancy approval before use. Wind-connection and flood-elevation verification apply here as in the coastal counties.

Confirm bookings rather than assuming them, and give the notice the office asks for — an unconfirmed inspection request is a scheduling risk you can remove with one call or visit.

Do not cover work before the required inspection has been approved. Keep the issued permit, the approved plans, energy and wind documentation, product listings, any special-inspection reports and your correction responses available on site.

Pearl River County permit search and official resources

Permit records in Mississippi sit with the local authority that issued them — where the county enforces the code, it holds the building permit, the inspection history and the certificate of occupancy for work in unincorporated Pearl River County. If you are buying, refinancing or renovating, ask what it holds for the parcel, and confirm that past work was permitted rather than assuming it was.

These are the primary sources behind this guide. Codes, fee schedules and portal procedures change, and a jurisdiction’s own published packet can lag — the adopted ordinance governs, not an un-updated handout. Confirm the position for your filing date.

Frequently asked questions

Can Pearl River County opt out of building codes?

No. It is one of the five coastal counties under 2006 House Bill 1406 that cannot opt out, and it enforces hurricane wind and flood provisions even though it lies inland.

Does Marine Resources wetland permitting apply here?

No. Marine Resources wetland permitting covers the coastal zone of Hancock, Harrison and Jackson counties; Pearl River enforces the wind and flood code but is outside that zone.

What wind design applies here?

High design wind speeds with engineered connections and flood-elevation provisions, applied under the coastal mandate despite the inland location.

Does the county or the city issue my permit?

Work inside Picayune and Poplarville files with those cities; unincorporated ground is a county matter for the Planning & Building Department. Part of the City of Lumberton, which lies mostly in Lamar County, is also in Pearl River County; for a parcel there, confirm with the Planning & Building Department whether the city or the county issues the permit.

Do I need a contractor licence for a small job?

A state residential builder licence is required above $50,000 for a new home, and a remodeling or roofing licence above $10,000, but the coastal building permit and inspection still apply below that.

How do I run a Pearl River County permit search?

Ask the county what it holds for the parcel; city work sits with the city that issued it.
