Louisville's 600-Foot Rule: Check an Address First

Louisville's 600-foot rule for Airbnb and other short-term rentals bars a CUP-approved rental from operating within 600 feet of another CUP-approved rental, measured property line to property line. Approvals are first come first served, so the first owner on a block to get through the conditional use permit process effectively claims the surrounding 600 feet. That means a property that looks perfect on paper can be legally unusable as a non-owner-occupied short-term rental. The only way to know is to check for existing approvals near the address before you close, not after.

How the Separation Requirement Works

The rule is simple to state and easy to misjudge in practice. Two details matter most: how the distance is measured and which rentals it covers.

Property line to property line, not front door to front door

The 600 feet is measured from property line to property line. It is not measured from front door to front door, and it is not measured by walking or driving distance.

That difference adds up. On a block of narrow city lots, two houses that look well apart from the sidewalk can have lot lines much closer than the homes themselves. A deep or wide lot pulls its boundary closer to the neighbors in every direction. If you are estimating by eye from a street view, you are likely underestimating how much of the surrounding area an existing approval covers.

When in doubt, measure from the nearest edge of your lot to the nearest edge of any lot with an existing approval. If that number is under 600 feet, assume the rule applies until planning staff tell you otherwise.

Why it applies only to CUP-approved rentals

The separation requirement is tied to the conditional use permit path. In Louisville, that path covers non-owner-occupied short-term rentals, plus owner-occupied rentals in Old Louisville and Limerick, where even primary residences need a CUP.

Owner-occupied rentals in most of the city register without a CUP, so they are not the rentals the 600-foot rule measures against. In practice, that means an owner-occupied rental next door does not block your CUP application the way a CUP-approved rental would. It also means the rule is aimed squarely at investors, because investor properties are the ones that need the permit.

Checking an Address Before You Commit

The 600-foot rule is a pre-purchase problem. Once you own the property, there is nothing to fix. The rental either clears the separation requirement or it does not.

Finding existing approvals near a property

Start by building a list of CUP-approved short-term rentals near the address you are considering. A few places to look:

• Louisville Metro planning staff. The pre-application conference exists to surface issues like this before you file. Ask directly whether any approved short-term rental CUPs sit within 600 feet of the address.
• Board of Zoning Adjustment records. Every CUP goes through a public hearing, so approvals leave a public record. Past hearing agendas and decisions for the surrounding streets are worth reviewing.
• Active listings on the block. A listing is not proof of a CUP, and some listings may be owner-occupied or unregistered. But a cluster of whole-home listings on nearby streets is a sign to dig further before you make an offer.

Do this before the offer, or build time for it into your contingency period. Six months into a CUP process is the wrong time to learn a neighbor already holds the approval that blocks yours.

The first-come-first-served dynamic in saturated blocks

Because approvals are first come first served, every approval on a block shrinks the space left for the next one. In neighborhoods where short-term rental demand is strong, the most desirable streets can fill up. Once they do, a new CUP there is unlikely no matter how good the property is.

This also cuts the other way. If you are in the middle of a CUP process and another owner nearby is doing the same thing, the timing of approvals matters. The rule rewards owners who start early, file complete applications, and do not lose weeks to avoidable delays.

The Exceptions Most Owners Miss

Most addresses either clear the 600 feet or they do not. A few situations deserve a closer look before you write a property off or assume it is clear.

Duplexes and carriage houses

Properties with more than one unit on a single lot, such as a duplex or a main house with a carriage house, raise questions that the basic rule does not answer on its own. How many units can operate, whether each unit is treated separately, and how the rule interacts with an owner living in one unit are all questions to put to planning staff for your specific property.

Do not assume a two-unit property doubles your short-term rental capacity. Get the answer in writing from the city before the purchase price assumes it.

When a waiver is realistic and when it is not

Louisville does allow waiver requests, but a waiver is not a formality and it is not guaranteed. The Board of Zoning Adjustment weighs the request at a public hearing, and neighbors can speak against it.

A waiver request is more realistic when the application is otherwise strong: complete paperwork, a clear local operating plan, and no organized neighborhood opposition. It is much less realistic on a block that already has several approvals, where neighbors have raised concerns about short-term rentals, or where the separation shortfall is large. If the purchase only works with a waiver, treat that as a risk in your numbers, not as a plan.
