Do you need a building permit in Cave City, KY?

Cave City requires a building permit from the City Building Inspector or designee before constructing any building or structure, or an addition that adds square footage.1 Cave City also applies its adopted Kentucky Uniform State Building Code to single-family dwellings constructed or remodeled inside city limits.9

A Cave City residential building permit depends on plans meeting that code, and the inspector checks construction as work progresses.1011 Before occupying a single- or double-family residence in Cave City, obtain the city certificate of occupancy or compliance.7

Who issues Cave City building permits, and what are the fees?

The Cave City Building Inspector or designee issues city building permits; ask Cave City Hall to connect you with that office.112 Submit the city application form, plans and specifications, and pay inspection fees with the application.10

Cave City’s published building-permit schedule includes inspections and requires advance payment.13 For single- and double-family dwellings, the first 1,000 square feet or fraction costs $30, with $2 for each additional 100 square feet or fraction.13 For additions, the first 1,000 square feet or fraction costs $20, with $1 for each additional 100 square feet or fraction.13 Ask the City Building Inspector for the current project total before submitting plans.10

Does Cave City have zoning, and what does that mean for RVs and tiny homes?

Cave City’s zoning ordinance applies to land inside city limits.2 The city’s planning page identifies the Joint City-County Planning Commission of Barren County as providing planning review and recommendations for Cave City, and offers variance and conditional-use application forms.3

Before choosing a house footprint, ask the city planning contact and joint planning commission for the parcel’s zoning district and applicable lot-size, setback, height and dwelling-size requirements.214 We could not confirm the parcel-specific rules for RV occupancy, tiny homes, mobile homes or accessory dwellings; ask those offices about the proposed use before purchasing land or a unit.314

How do septic permits work inside Cave City?

Cave City building approval does not replace the local health department’s septic permit: Kentucky requires a site evaluation and a permit before constructing any portion of an onsite sewage system.16 The Barren River District Health Department evaluates soils, reviews installation drawings before issuing septic permits and inspects systems after installation.515

For a Cave City parcel without a sewer connection, start with the district’s Onsite Sewage Program before committing to the building layout.16 Barren County’s soil data rate about 40% of soils “not limited” for a conventional septic drain field; that countywide figure does not determine whether an individual Cave City lot can support septic, so obtain the site evaluation.176

What are the steps for building a home in Cave City?

  1. Ask Cave City’s planning contact and the joint planning commission to identify the zoning district and review the proposed residential use and site layout.2314
  2. If the home will use septic, arrange the health department’s site evaluation and obtain the septic permit before system construction.65
  3. Submit the Cave City building application, plans, specifications and inspection fees to the City Building Inspector, and obtain the building permit before construction.101
  4. Coordinate city inspections during construction and health-department inspection after septic installation.1115
  5. Obtain the city certificate of occupancy or compliance before moving into a single- or double-family residence.7

What should you check before buying land in Cave City?

Ask Cave City Hall about public water and sewer availability and whether the proposed home must connect; we could not confirm a city connection threshold.12 For a private well, Kentucky does not require an owner permit application or fee for construction or abandonment, but construction, modification and abandonment must use a Kentucky Certified Water Well Driller.8

Ask the City Building Inspector about owner-performed construction before relying on an owner-builder exemption; Cave City still requires the city building application and code review.10 For land outside Cave City limits, consult the Barren County guide rather than applying Cave City’s city-limits zoning ordinance.2

Watch-outs

  • Obtain Cave City’s certificate of occupancy or compliance before moving into a single- or double-family residence, even after construction is finished.7
  • We could not confirm permission to live in an RV while building in Cave City; ask the city planning contact about the exact parcel and proposed duration.3
  • Kentucky generally prohibits seepage pits, cesspools and dry wells for onsite sewage disposal, subject to limited regulatory exceptions; discuss sanitation plans with the health department.1819
