HB 791 Montana House · 2025 Regular Session

Generally revise nuisance laws

HB 791 generally revises the state's public and private nuisance laws, affecting how individuals and government entities can address conditions interfering with property use or public rights. The bill redefines both public and private nuisances and explicitly lists activities and conditions that cannot be considered a nuisance, such as authorized actions, noises from shooting ranges, and established agricultural operations. It also limits the remedies available to government entities in public nuisance actions to injunctions and abatement costs, excluding various forms of damages. This legislation abrogates common law nuisance and supersedes conflicting state statutes.

MODERATE
The bill was amended to remove the repeal of several specific sections of the Montana Code Annotated, which likely means those laws remain in effect despite this bill. Additionally, the definition of 'government entity' was clarified to exclude federal, state, or local agencies from certain preemption rules, and the preemption clause was narrowed to only apply where common law conflicts with the new chapter. A new section was added establishing liability for public nuisance.
Scope change
The bill's scope was reduced by removing the repeal of existing statutes, and its applicability was narrowed by clarifying that federal, state, and local government entities are not subject to the preemption of common law nuisance claims.
SCOPE

Removed the repeal of sections 27-30-102, 27-30-103, 27-30-104, 27-30-105, 27-30-201, 27-30-202, 27-30-203, 27-30-301, and 27-30-302, meaning these laws will not be abolished by this bill.

DEFINITION

Modified the definition of 'government entity' to exclude federal, state, or local governmental entities or agencies from the scope of certain orders and notices.

ENFORCEMENT

Modified the preemption clause to limit the bill's authority to situations where common law is inconsistent with the chapter, rather than broadly abrogating all common law nuisance.

Added a new section establishing liability for public nuisance, allowing individuals to be subject to such claims.
