Building permits, zoning and land rules in Holmes County, Mississippi

Holmes County, Mississippi has not published a residential building-permit requirement or application process that we could confirm for unincorporated land¹. That is not the same as saying no permit is required. Mississippi's statewide framework directed counties and municipalities to enact uniform building codes unless they opted out before the state deadline, but the framework alone does not establish Holmes County's current adopted code or enforcement process⁹.

Separately, the Mississippi State Fire Marshal has adopted the 2024 International Fire Code and International Building Code, but that statewide step does not tell you whether Holmes County has adopted its own local building code¹⁰.

Before buying materials or hiring a crew, give the Holmes County Administrator the parcel number, street or road, proposed use and a short description of the structure². Ask which office issues the permit, which code applies, what plans are needed, what inspections occur and whether a certificate of occupancy is required. If the property lies inside a municipality, ask that city or town instead, because the county's own business-license page distinguishes locations inside city limits from those outside them².

The practical first call for an unincorporated Holmes County project is the Holmes County Administrator at 662-834-0911, 408 Court Square, Lexington². The official county directory says the Administrator carries out county affairs under the Board of Supervisors' policies, but it does not identify a separate building, planning or zoning department². Ask the Administrator to identify the current permitting and floodplain contacts before filing anything.

For septic questions, contact the Holmes County Health Department at 662-834-3142, 22545 Depot St in Lexington¹¹. For a driveway or work in a county right-of-way, start with the Board of Supervisors; each supervisor is responsible for county roads and bridges within that district¹². A new driveway connecting to a Mississippi state highway goes through the Mississippi Department of Transportation instead⁸.

We could not confirm a Holmes County zoning ordinance, zoning map or an official statement that unincorporated Holmes County has no zoning³. Do not treat the absence of a published ordinance as permission for any use. Before closing, ask the County Administrator whether the parcel is subject to county land-use controls, subdivision conditions, floodplain rules, deed restrictions or a municipality's jurisdiction².

The same gap applies to setbacks, minimum lot size, minimum dwelling size, building height, lot coverage, accessory dwellings, manufactured homes and agricultural buildings³. Get the answer tied to the exact parcel and proposed structure. If the seller says the land is unrestricted, request the source in writing and verify it with the county office. A recorded private covenant can also limit use even when a government zoning rule cannot be confirmed; review the deed and title materials with the appropriate local professional.

New residential on-site wastewater systems in Holmes County require a Mississippi State Department of Health soil and site evaluation and approval⁴. The residential process asks for the legal description, a plot plan, written directions and either the fee or an email address for invoicing⁵. The state permit is also required for a water meter, and state law requires a permanent sewage-disposal solution (a sewer line or a septic system) before a water utility can connect a permanent meter¹³. If a sewer line is within 1 mile, the Department refers the application for connection and requires a letter of rejection from the sewer provider before it proceeds¹³. The Department's current fee for a Notice of Intent plus Final Approval is $197.50, and a Notice of Intent plus Exemption is $100¹³. Start with the Holmes County Health Department at 662-834-3142 for the local contact and inspection routing¹¹.

Installation inspection is not automatic in every case: the application lets the owner select the MSDH inspection path, and MSDH advises selecting inspection when financing is involved⁵. A certified installer must contact the Department 24 hours before construction begins to schedule the inspection under the reviewed application instructions⁵. Site conditions deserve attention before closing because only about 19% of Holmes County soils avoid the USDA's severe-limit rating for a conventional drain field¹⁴. That rating does not decide a permit, but it makes an early site evaluation especially valuable.

We could not confirm a Holmes County rule allowing or prohibiting long-term RV occupancy on private land in unincorporated areas³. We also could not confirm county rules for temporary camping, tiny-home occupancy, manufactured homes, minimum dwelling size or residential setbacks³. Ask the County Administrator about the exact parcel and proposed setup before buying an RV, shed conversion or small dwelling for the site².

Separate the questions when you call: ask whether the unit may be placed, whether it may be occupied, whether utility connections are allowed, and whether a permit or inspection is required. Septic approval remains a separate state-health step for a residential on-site system⁴, and Mississippi classifies gray water as wastewater that must go to a central sewer or a septic system, so an off-grid setup cannot discharge it on the ground¹³. Rules for Pearl River Valley Water Supply District campgrounds do not answer private-land occupancy in Holmes County, so campground stay limits should not be used as a substitute for a county answer.

1. Confirm whether the parcel is unincorporated and ask the Holmes County Administrator which building, zoning and floodplain requirements apply^1,2,3.
2. Apply for the MSDH soil and site evaluation before fixing the house location; the application requires a legal description, plot plan and written directions⁵.
3. Confirm the water source. A well with surface casing at least 6 inches in diameter requires a state groundwater-withdrawal permit, subject to exclusions⁷.
4. Ask the correct road authority about access. The county supervisors handle county roads by district, while a new connection to a state highway needs an MDOT permit^8,12.
5. Submit whatever plans and applications the county identifies, and get the required approvals before work begins¹.
6. Have the septic installer give the Department 24 hours' notice before construction when an MSDH inspection is selected⁵.

An owner working on the owner's own residence may qualify for Mississippi's residential-builder licensing exemption, but that exemption does not cancel a locally required permit or inspection⁶.

Start with wastewater and access. Only about 19% of Holmes County soils avoid a severe-limit rating for conventional drain fields, so make the MSDH site evaluation part of due diligence rather than waiting until after closing¹⁴. Confirm legal and physical access, and remember that a new driveway onto a state highway needs an MDOT permit⁸. Ask the Board of Supervisors about county-road issues for the parcel's district¹².

Next, obtain parcel-specific answers on building permits, zoning and floodplain review from the County Administrator because those county processes remain unconfirmed in the published material^1,2,3. Holmes County averages about 56 inches of precipitation a year and is about 64% wooded, so walk the property after rain and budget for drainage, clearing and road work where needed¹⁴. The effective property-tax rate is about 0.9%, with a median annual bill near $695¹⁴.
