relative to the taxation of non-primary residences.

HB 1580 imposes a 0.75% annual surcharge on the assessed value of residential properties not used as the owner’s primary residence (defined as living there 183+ days yearly and listing it for voter/driver’s license/tax purposes). It directly affects owners of second homes, vacation properties, or vacant residential properties (including single-family homes, condos, and mobile homes). Key exemptions include primary residences, long-term rentals (6+ months), properties under $500,000, and those qualifying for existing tax exemptions. Revenue collected must be used by municipalities to reduce property taxes or fund local services like schools and infrastructure. The bill takes effect April 1, 2027.
