Unincorporated Trigg County, Kentucky appears not to require a single-family building permit, but Kentucky allows a local ordinance to require one12. Inside Cadiz, the city requires building permits and sets zoning34. Septic permits inside and outside Cadiz remain with the Trigg County Health Department5.

Do you need a building permit in Trigg County, Kentucky?

A single-family building permit appears unnecessary in unincorporated Trigg County1. Kentucky's exemptions are conditional: each approval is unnecessary only when no local ordinance requires it21314. We could not confirm a current Trigg County ordinance that resolves that condition, so ask the Cadiz-Trigg County Planning Commission before construction15.

The Kentucky Residential Code governs single-family homes, two-family homes and townhouses even without a local inspection program; HVAC and electrical inspections still apply where no single-family building inspection program exists168. A qualifying farm structure outside a municipality may fall under Kentucky's agricultural building-code exclusion, but retail use, regular employment by 10 or more people, and timber-product storage or processing are excluded17. Plumbing work requires a state plumbing permit18. Owner-performed plumbing for a personal residence requires advance application, an affidavit and code-compliant work personally performed by the owner; only 1 new-home homeowner plumbing permit may be issued per individual in a 5-year period910. HVAC has separate homeowner-permit conditions, including system sizing and duct and piping design10.

Who issues building permits in Trigg County?

We could not confirm an office issuing single-family building permits in unincorporated Trigg County; ask the Cadiz-Trigg County Planning Commission15. Ask the Cadiz-Trigg County Planning Commission at 270-350-5566 or secretary@ctcplanning.com whether a local ordinance requires a building permit for the parcel152. Inside Cadiz, the city Building Inspector must issue a building permit before excavation, construction, moving or alteration of buildings or accessory buildings3. Cadiz also publishes a zoning-permit application, while septic permits countywide remain with the Trigg County Health Department195.

Trigg County 911 receives the required address-request form for new structures at P.O. Box 672, Cadiz, KY 42211, phone (270) 522-7445 or ljenkins@trigg911.com2021. The Trigg County Road Department handles entrance culverts on county roads at the same mailing address, phone (270) 522-8377 or roadforeman@triggcounty.com22. A driveway connecting to the state highway system instead requires Kentucky Transportation Cabinet approval23.

Does Trigg County have zoning?

Trigg County has no countywide zoning; inside Cadiz, city zoning districts apply and the city publishes a zoning-permit application6424. Septic permits for parcels inside and outside Cadiz remain with the Trigg County Health Department5. Some subdivisions also have recorded deed restrictions, so a rural parcel can carry private limits even where county zoning is absent6.

We could not confirm countywide numerical rules for minimum home size, setbacks, lot coverage or building height; ask the Cadiz-Trigg County Planning Commission15. Ask the Cadiz-Trigg County Planning Commission about the exact parcel and obtain the recorded plat and deed restrictions before designing a home15. Land division can trigger another layer: subdivision within a Kentucky planning-unit jurisdiction requires planning-commission approval before the plat may be recorded, while a qualifying agricultural division that creates no new street can fall outside the statutory subdivision definition2526.

How do septic permits work in Trigg County?

The Trigg County Health Department administers onsite sewage locally under Kentucky's statewide program27. Contact the office at 196 Main Street, PO Box 191, Cadiz, KY 42211 or (270) 522-812128. A site evaluation comes first, and the permit must be issued before any part of the onsite system is built7. Trigg County's local guidance says a septic building lot must be at least a half-acre5.

After installation, the system must be inspected by a certified inspector29. Only 23.5% of Trigg County soils are rated “not limited” for a conventional septic drain field; the remaining soils have some degree of limitation, so a site evaluation may point to an engineered system rather than rule out septic30. Kentucky may allow an alternative system when the proposed conventional design is not approvable, and approved composting toilets or a separated greywater system may reduce design flow; the remaining onsite system still needs approval, a permit, and inspection731.

Can you live in an RV or tiny home in Trigg County?

We could not confirm a Trigg County rule that allows long-term RV occupancy or a tiny home as a permanent dwelling on an individual parcel outside Cadiz; ask the Cadiz-Trigg County Planning Commission15. The reported absence of countywide zoning does not by itself establish that either use is lawful, and recorded subdivision restrictions may still control a specific property6. Ask the Cadiz-Trigg County Planning Commission about zoning approval and the Trigg County Health Department about the septic permit1528.

In Cadiz residential districts, use of a mobile home as a dwelling or business for more than 30 days outside a licensed or approved mobile-home park is prohibited; modular homes on permanent foundations are allowed in city subdivisions subject to subdivision regulations and deed restrictions32. A tiny home used as a dwelling must still satisfy the Kentucky Residential Code and approved sewage requirements3334.

What are the steps to build a home in Trigg County?

  1. Confirm whether the parcel is in Cadiz, a subdivision, or unincorporated Trigg County; obtain the plat and recorded deed restrictions where applicable615.
  2. Ask the Planning Commission whether a single-family building permit, building inspection, or certificate of occupancy is required by local ordinance; inside Cadiz, obtain the city building permit and apply for zoning approval21314319.
  3. Request the required address for the new structure from Trigg County 91121.
  4. Arrange the septic site evaluation and obtain the septic permit before construction; the local septic minimum is a half-acre75.
  5. Apply to the Kentucky Transportation Cabinet for a state-highway driveway, or coordinate an entrance culvert on a county road with the Trigg County Road Department2322.
  6. Check the flood map before site work because floodplain construction, demolition, or renovation requires a state floodplain permit, and participating local governments also issue local floodplain permits1235.
  7. Obtain the state plumbing permit and use a Kentucky Certified Water Well Driller if the property needs a private well1811.

What should you check before buying land in Trigg County?

Start with jurisdiction and title: confirm the Cadiz city boundary, review the recorded plat and deed restrictions, and ask the Planning Commission whether zoning approval or subdivision review affects the project63625. Rental property inside Cadiz is subject to the city's published privilege-license tax return and fee schedule, but we could not confirm a separate short-term-rental rule37. Then make the purchase contingent on a satisfactory septic site evaluation. Only 23.5% of Trigg County soils are rated “not limited” for a conventional drain field; other sites may need an engineered system, and the local septic lot minimum is a half-acre305.

Check road access and flood exposure before choosing a homesite; state-highway access needs Transportation Cabinet approval, while development in, along, or across a stream needs a Kentucky Division of Water floodplain permit and may also need a local floodplain permit2335. Trigg County is 59.3% wooded, while 60.5% of its land has a slope of 15% or less, but parcel-level clearing, drainage, and grade can differ sharply from county averages3839. For budget context, the county's median property-tax bill is about $1,065 per year and its effective property-tax rate is about 0.6%4041.

Watch-outs

  • Cadiz requires city building permits; the apparent single-family building-permit exemption in unincorporated Trigg County remains subject to any local ordinance312.
  • A half-acre is the local minimum for a septic building lot, but a site evaluation still determines whether the soil and proposed system are acceptable57.
  • Long-term RV and tiny-home occupancy outside Cadiz remain unconfirmed; ask the Planning Commission and Health Department before buying land for either use1528.
