Holmes County, Mississippi has not published a county residential building-permit process that we could confirm, so ask the County Administrator before planning work in an unincorporated area12. County zoning is also unconfirmed3. A new residential septic system does require a soil and site evaluation and approval through the Mississippi State Department of Health4.

Do you need a building permit in Holmes County, MS?
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.
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.
Who handles Holmes County building and land-use questions?
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 Lexington10. 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 district11. A new driveway connecting to a Mississippi state highway goes through the Mississippi Department of Transportation instead8.
Does Holmes County have zoning?
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.
How do septic permits work in Holmes County?
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. Start with the Holmes County Health Department at 662-834-3142 for the local contact and inspection routing10.
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 involved12. A certified installer must contact the Department 24 hours before construction begins to schedule the inspection under the reviewed application instructions12. 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 field13. That rating does not decide a permit, but it makes an early site evaluation especially valuable.
Can you live in an RV or tiny home on land in Holmes County?
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. 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.
Building a home in Holmes County: what are the steps?
- Confirm whether the parcel is unincorporated and ask the Holmes County Administrator which building, zoning and floodplain requirements apply132.
- Apply for the MSDH soil and site evaluation before fixing the house location; the application requires a legal description, plot plan and written directions5.
- Confirm the water source. A well with surface casing at least 6 inches in diameter requires a state groundwater-withdrawal permit, subject to exclusions7.
- 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 permit118.
- Submit whatever plans and applications the county identifies, and get the required approvals before work begins1.
- Have the septic installer give the Department 24 hours' notice before construction when an MSDH inspection is selected12.
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.
What should you check before buying land in Holmes County?
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 closing13. 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 district11.
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 material132. 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 needed1415. The effective property-tax rate is about 0.9%, with a median annual bill near $6951617.
Watch-outs
- Do not assume that a missing online permit page means no permit is required; Holmes County's residential permitting and inspection process remains unconfirmed, so ask the County Administrator before work begins12.
- Only about 19% of Holmes County soils avoid a severe-limit rating for a conventional drain field, so complete the MSDH site evaluation before choosing the house site135.
- Private-land RV living and tiny-home occupancy remain unconfirmed in Holmes County; get parcel-specific answers before purchasing or placing a unit32.
- A driveway connecting to a Mississippi state highway requires an MDOT permit; county-road questions begin with the supervisor responsible for that district811.
