Why ADUs collide with declarations more often than other land-use changes

An accessory dwelling unit is unusually likely to run into covenant language, for a reason specific to how declarations are drafted.

Most residential declarations contain some version of a single-family or one-dwelling restriction. That language predates the current ADU policy wave by decades and was written to prevent duplex conversion, not to address a detached studio over a garage. Whether it reaches an ADU depends on wording that was never drafted with the question in mind.

Common formulations diverge sharply in effect:

• “One single-family dwelling per lot” — likely reaches a detached ADU, since the ADU is a second dwelling.
• “Residential use only” — probably does not, since an ADU is residential.
• Restrictions on structures, phrased around outbuildings or accessory structures with size and placement limits — may reach the ADU as a structure even where the use is permitted.

The five-foot rear setback sharpens this last one. Municipal setbacks and covenant setbacks are independent, and declarations in Juneau subdivisions frequently specify greater distances than the code now requires. An owner meeting the municipal standard may still be short under the declaration — and the architectural review committee, not the city, is where that surfaces.

The Alaska position, stated carefully

Alaska has enacted no statute overriding private covenants for accessory dwelling units. That is not an oversight to be read around: several states have legislated exactly this, voiding conflicting covenants within defined parameters, and Alaska's 34th Legislature introduced nothing on ADUs, density or covenants at all.

So in Alaska the layers remain independent, and a declaration that restricts a second dwelling is unaffected by a municipality deciding to permit one. The general principle — that the more restrictive of public regulation and private covenant controls in practice — has no Alaska appellate decision applying it to ADUs specifically.

What a board can establish without waiting for law to develop is what its own declaration actually says. That reading is more often ambiguous than boards expect, and the ambiguity itself matters: Alaska covenant-construction principles resolve genuine ambiguity in favour of the free use of property, which is the opposite of the direction a board enforcing a restriction would prefer.

The other Juneau change worth knowing

Separately, Ordinance 2025-23(b)am, adopted May 20, 2025, requires short-term rental marketplace facilitators to collect and remit CBJ sales tax and hotel room tax, and to ensure every active listing displays a valid CBJ registration number. Registration itself dates to 2023, with a $100-per-day penalty for unregistered live listings.²

The mechanism mirrors Anchorage's: platform-side enforcement makes unregistered operation harder to sustain, and the resulting registry is a public record of which units are being marketed — information an association previously had no reliable way to obtain.

What to watch next

This was Phase 1. Juneau's Title 49 rewrite is a multi-phase project, and later phases will reach zoning districts and dimensional standards directly. Whether any subsequent phase addresses the interaction with private covenants is unknown; Phase 1 did not.

For associations in the City and Borough, the near-term question is not what Juneau permits but what their own recorded restrictions say about second dwellings — because that is now the only layer doing the work.
