Primary-source summary
**Last reviewed**: April 2026
**Activity level**: Low — Alaska retains a strongly local-control / home-rule framework. No MBTA-Communities-style mandate, no statewide ADU or density preemption, no statewide STR preemption. Zoning authority is delegated through AS 29.40, and the unusual borough/city unified structure is the dominant wrinkle.Trigger predicate
When this evaluates true for a parcel, the law's preempted fields take precedence over base zoning.

zoning_authority_source | override | borough_or_city_per_borough_class | Inside first-class and home-rule boroughs, areawide borough zoning governs (city sub-jurisdiction generally has no independent zoning power). Second-class boroughs may exercise the power. Cities in the unorganized borough may zone under their own charter; outside city limits in the unorganized borough no local zoning exists. |

Research notes
This is the enabling act, not a preemption. Recorded as an overlay because the borough-vs-city authority split and the unorganized-borough non-zoning gap are unique to Alaska and must drive how city records resolve their zoning_authority_source. There is no state override mechanism comparable to MBTA Section 3A or Massachusetts 40B. The state does not condition funding on local zoning compliance.
