What the bill would and would not have changed for a Kentucky community

The distinction is worth being exact about, because it is the one owners get wrong first.

Had HB 203 passed, an owner in a covenanted Kentucky subdivision would have gained a right against the city or county — the zoning ordinance could no longer have stood in the way of one ADU. The owner would have gained nothing against the association. A declaration restricting the lot to one single-family dwelling, prohibiting detached accessory structures, or requiring architectural approval would have continued to control, and would have been the operative barrier.

That is the same structure Kentucky has already legislated elsewhere. In 2025, HB 160 stripped local governments of the power to zone qualified manufactured homes out of single-family districts — effective 1 July 2026 — while expressly preserving “restrictions contained in recorded deeds, covenants, or developers' subdivision restrictions.” The public layer moves; the private layer does not.

The short-term rental provision that was easy to miss

One clause in HB 203 cut against the deregulatory grain, and it is the one most relevant to associations. A planning unit would have retained power to “[p]rohibit or restrict an accessory dwelling unit from being rented for terms of less than thirty (30) days.”

The drafters evidently anticipated the objection that ADU legalisation is short-term-rental legalisation by another route, and left local governments the tool to answer it. For an association, that would have mattered: in a city that used the power, the ADU would have been available for long-term tenancy only, which is a very different proposition for a community's parking, density and traffic than a second unit listed nightly.

Since the bill failed, none of this is in force. But the clause is a good indicator of where the drafting will sit if it returns.

What Kentucky ADU law actually is right now

There is no statewide ADU statute. What exists is narrower and runs the opposite way.

KRS 383.199, created by 2025 SB 129 and effective 27 June 2025, applies only in a county containing a consolidated local government — that is, Jefferson County and Louisville Metro alone. It provides that for new leases initiated after the Act's effective date, an owner shall not lease or allow to be occupied any single-family home, multifamily housing unit, or accessory dwelling unit on a lot containing a single-family home in a traditional single-family home zone, unless the owner primarily resides in one of the units on the lot. The restriction does not apply to a lot containing only one single-family home and no ADU.

So in Louisville the state has imposed an owner-occupancy condition — a restriction, not an authorisation, and one that binds even where the covenants are silent. Elsewhere in Kentucky, ADUs are a matter of local zoning plus the declaration.

A board's options

• Read your declaration for the word your document actually uses. “One single-family dwelling per lot” is a very different restriction from “no structure other than a single-family dwelling and a private garage.” The first may not reach an internal ADU at all.
• Decide the policy before the application. A board with no position on ADUs will make its first decision under pressure, and Kentucky's courts have shown recently that a refusal which cannot point to a provision is exposed — in May 2026 the Court of Appeals held arbitrary rejection of plans conforming to specific and unambiguous covenants unenforceable.
• In Louisville, know that KRS 383.199 exists. An association fielding a question about renting a backyard cottage has a statutory answer independent of the declaration.
• Do not tell owners the legislature has legalised ADUs. It has not, and the bill that would have has now failed twice.

What to watch next

HB 203 was filed in 2025 as HB 576 and refiled in 2026 by the same sponsor. That pattern makes a third filing in the 2027 Regular Session, which convenes in January for a 30-day term, the most likely course — though Kentucky abolished bill pre-filing in 2022, so no 2027 bill request is publicly visible and nothing is confirmed.

The Community Associations Institute's national trends work lists Kentucky under accessory dwelling units, which is a reflection of HB 203 rather than of anything enacted. If a bill returns, the questions for a Kentucky board are the same two: does it bind only “a planning unit,” and does it keep the local power to bar short-term rental of the ADU.
