NWLEPG describes inspection and final certification of replacement wastewater installations for compliance with county codes and Kansas standards¹⁴. Confirm the wastewater authority for property inside Colby before applying.

NWLEPG sets the fee schedule for sanitary-code permits and licenses, and payment is due with the application; the code does not state the amounts⁵. Call NWLEPG for the current septic-permit fee.

Within Colby, uses and construction must follow the applicable zoning district³. Colby limits tiny homes to approved mobile-home communities zoned R-2 MH⁹. A residential-design manufactured home must have at least 888 square feet of heated floor area, but that city standard is not a countywide minimum dwelling size³.

Kansas exempts land and buildings used only for agricultural purposes from zoning adopted under the state planning-and-zoning framework, except floodplain regulations¹¹. Thomas County sanitary-code and subdivision review can still apply to rural development⁵.

How do septic permits work in Thomas County, Kansas?

Anyone installing, removing, altering, repairing or replacing an onsite wastewater system in unincorporated Thomas County must obtain a septic permit before work begins.

Anyone installing, removing, altering, repairing or replacing an onsite wastewater system in unincorporated Thomas County must obtain a septic permit before work begins⁵. NWLEPG administers the sanitary code and handles the required review^5,14.

A lot or tract seeking an onsite-wastewater permit must contain at least 3 acres unless a variance is granted⁵. The septic tank must be at least 10 feet from a building foundation; the wastewater system must be at least 25 feet from a property line, 50 feet from a private well or surface watercourse, and 100 feet from a public water-supply well⁵. A holding tank must have all-weather road or driveway access allowing pumping equipment within 10 feet of its service manhole⁵.

About 87.5% of Thomas County soils are rated without severe limits for a conventional drain field, but the parcel still needs septic-permit review^5,15. Domestic wastewater must use an approved collection, lagoon, septic or alternative system; seepage pits, cesspools, dry wells and surface discharge from a private onsite system are not allowed¹⁶.

Can you live in an RV or tiny home in Thomas County, Kansas?

We could not confirm a rule allowing or prohibiting long-term RV living, temporary camping or tiny-home occupancy on unincorporated private land.

We could not confirm a rule allowing or prohibiting long-term RV living, temporary camping or tiny-home occupancy on unincorporated private land⁷. Ask Thomas County about the proposed use and parcel before buying land or moving an RV or tiny home onto it. A Kansas property owner may personally perform roofing work, or use employees, without a registered roofing contractor, but that narrow rule is not a general exemption from building permits, inspections or contractor licensing¹⁰.

A narrow sanitary-code provision allows a temporary hardship manufactured home to connect to an existing onsite sanitation system after a natural disaster, accidental destruction of a permanent dwelling or family hardship, when Thomas County regulations permit the situation and the connection passes inspection⁵. That sanitation provision does not grant general permission to occupy a manufactured home, RV or tiny home anywhere in Thomas County⁵.

Inside Colby, a tiny home may be located only in an approved mobile-home community zoned R-2 MH⁹. Colby's rule does not decide what is allowed on unincorporated land⁹.

Building a home in Thomas County: what are the steps?

Obtain the county well permit before drilling a household, lawn-and-garden or livestock or pasture well; the listed fee is $125⁸.

If the driveway connects to a Kansas state highway, obtain the state highway permit before working in the right-of-way¹⁷. We could not confirm a county driveway-permit requirement for access connecting only to a local road.

What should you check before buying land in Thomas County?

Start with jurisdiction because Colby's building permits and municipal zoning do not establish the rules for every parcel in Thomas County.

Start with jurisdiction because Colby's building permits and municipal zoning do not establish the rules for every parcel in Thomas County^2,3,4. Then verify that an unincorporated tract can satisfy NWLEPG's wastewater review and the 3-acre septic-permit minimum unless a variance is available⁵. Before developing an unincorporated subdivision, obtain approval of its wastewater plans; a subdivision is a plat creating 2 or more lots⁵.

Water deserves early attention because Thomas County averages about 20.4 inches of precipitation a year and experiences severe drought in about 28.5% of years¹⁵. Thomas County requires permits for household, lawn-and-garden and livestock or pasture wells, with a listed fee of $125⁸.

All of Thomas County's land is at a slope of 15% or less, while about 0.2% is wooded¹⁵. The nearest city of 100,000 or more is about 197 miles from the county center¹⁵. Also confirm legal access and whether a state-highway driveway permit applies¹⁷.

Watch-outs

Thomas County does not publish a direct statement of its rural building-permit rule, so confirm the parcel and project with the county before construction¹.
We could not confirm the rules for RV living, temporary camping, tiny-home occupancy or general minimum dwelling size on unincorporated Thomas County land; ask the county before relying on any of those uses⁷.
Colby issues building permits and administers municipal zoning, but zoning jurisdiction may vary near city limits; ask the city about land near Colby, while taking unincorporated septic-permit questions to NWLEPG^2,3,4,5.

Thomas County rules

Local zoningVaries (with conditions)
Aggregate local-zoning conclusion for Thomas County: incorporated municipalities may administer their own zoning, and city zoning may extend into otherwise-unzoned unincorporated land within statutory limits; this claim does not attribute each local ordinance to Thomas County.
- Kansas law provides that county zoning may cover all or part of unincorporated areas.
- Kansas law allows city zoning jurisdiction within the city and potentially up to three miles outside city limits where the land is not currently subject to county zoning, subject to the statutory half-distance limitation and written notice to the county.
- The City of Colby has an official zoning ordinance administered through the Colby-Thomas County Metropolitan Area Planning Commission and City governing body.
- The Colby ordinance is municipality-specific and does not establish zoning throughout Thomas County.
potential municipal extraterritorial zoning distance: <= 3 miles (The land must not currently be subject to county zoning and the statutory half-distance limitation applies.)
“The zoning regulations for a county shall define the area of zoning jurisdiction as all or any portion of the unincorporated area. The zoning regulations for a city shall define the zoning jurisdiction as including the area within the city limits and may also include land located outside the city which is not currently subject to county zoning regulations and is within three miles of the city limits, but in no case shall it include land which is located more than 1/2 the distance to another city.”

Water rights & wells in Thomas County

Whether a new home can legally get its own water here — the sub-state groundwater regime, from Kansas’s water agency.

Over-appropriated / declining

The aquifer here is over-appropriated and declining. A domestic well is usually still permit-exempt, but long-term supply is a genuine risk.

Household wellExempt — no permit or water right

Domestic use is statutorily exempt from the Kansas Water Appropriation Act, so a homeowner needs no state water right to drill a household well even inside a closed groundwater management district; only local/KDHE well-construction permitting applies.

Limit: Domestic use (household + livestock + ≤2 acres lawn/garden) requires no state appropriation permit
