This Idaho bill requires cities with more than 10,000 residents to allow starter home subdivisions by February 1, 2027, which are residential developments on at least four acres featuring smaller lots up to 1,500 square feet and compact homes. The law prohibits cities from enforcing ordinances that ban these subdivisions and sets specific limits on lot sizes, setbacks, and fees to make development more affordable while maintaining neighborhood compatibility. Cities retain the ability to deny approvals if infrastructure cannot support the development and must still comply with existing health, safety, and environmental regulations. The measure applies only to incorporated cities and does not affect historic districts or properties designated as historic landmarks.
This bill eliminates the proration of Idaho's homestead property tax exemption, allowing homeowners to receive the full exemption amount for the entire tax year if they qualify. It applies to owners who use their primary residence as their main dwelling and meet specific eligibility requirements, including uniform property appraisal certification by the state tax commission. Under the new rules, the exemption is calculated based on the full market value reduction rather than being divided by the number of days the property is occupied, and applications must be submitted by the end of the county's business year to receive the full benefit. The law also clarifies that if a homeowner's eligibility status changes during the year, taxes will be prorated only for the period after the status change occurs.
This bill updates Idaho law to allow accessory dwelling units (ADUs) in single-family homes and restricts restrictions that would ban them. It prohibits homeowner associations from enforcing rules that strictly forbid ADUs, except when property owners agree in writing to such restrictions. For cities with populations over 10,000, the bill requires local governments to allow one internal or detached ADU per lot in single-family zones by February 2027. Local governments must also stop imposing higher fees, stricter parking rules, or smaller size limits on ADUs compared to primary homes. The law ensures ADU projects are approved automatically if they meet standard zoning requirements, while still allowing cities to adopt less restrictive rules if they choose.
This bill updates Idaho state laws to allow manufactured homes to be placed on single-family residential lots, in addition to existing mobile home parks and subdivisions. It clarifies definitions for manufactured homes versus mobile homes and requires local governments to revise their comprehensive plans and zoning regulations to permit this siting option. The legislation also establishes specific placement standards for manufactured homes outside of parks, including minimum square footage, foundation requirements, roof design, and exterior appearance guidelines that must match surrounding homes. Local governments retain the ability to apply additional development standards that would apply to conventional single-family homes on the same lots, while the bill prohibits standards that unreasonably discourage needed housing.
This Idaho bill (H 707) creates a streamlined administrative process for splitting land containing an approved or existing accessory dwelling unit (ADU) or secondary structure, primarily affecting homeowners, builders, and lenders. It allows counties or cities to bypass full subdivision requirements if a lender verifies the split is needed for financing, provided the division doesn’t increase density, create new lots, or compromise access/utility. The process requires recording with the county and includes restrictions preventing further divisions or violations of zoning rules. The bill explicitly prohibits using this process for agricultural fragmentation or "subdivisions by another name," and takes effect on July 1, 2026.
Idaho's H 760 revises property tax exemptions for low-income housing owned by nonprofit organizations. It requires qualifying nonprofits to meet specific criteria, including federal 501(c)(3) status and ensuring no private benefit from tax exemptions. The bill mandates that 55% of units must rent to residents earning ≤60% of local median income, 20% to those earning ≤50%, and 25% to those earning ≤30%, with annual compliance reports to counties. It also adds protections preventing evictions for three months after certified medical emergencies and prohibits the exemption for properties with financing closed by July 1, 2026, unless undergoing rehabilitation.
Idaho's H 583 restricts local governments from banning short-term rentals or imposing most specific regulations on them, such as owner occupation requirements, professional management mandates, or rental day limits. It allows only basic safety measures (like smoke alarms and fire extinguishers) and requires counties/cities to treat short-term rentals equally with standard residential properties under zoning and building codes. The bill also prohibits local taxes on rental marketplaces (like Airbnb), instead requiring these platforms to collect and remit state and local lodging taxes to the state tax commission for distribution to local governments. This directly affects short-term rental owners, property managers, and online platforms operating in Idaho.
This Idaho bill (H 551) revises how counties assess property taxes for new construction. It requires counties to include only 90% of the taxable market value increase from new buildings, additions, or manufactured housing in property tax rolls - down from 100% under prior law. Exceptions apply to certain urban renewal areas (80% valuation) and specific cases like electricity generation improvements or previously exempt state university facilities. The change directly affects property owners who build new structures or make significant additions, as it reduces the tax burden on new construction value. The bill also clarifies reporting deadlines for county assessors and the state tax commission.
Idaho's H 610 revises the homestead property tax exemption, setting a new limit of the first $125,000 of a home's market value or 50% of that value (whichever is lower) as exempt from taxation. This directly affects Idaho homeowners who occupy their primary residence, requiring them to apply through county assessors with documentation confirming primary occupancy and compliance with uniform appraisal standards. Key provisions include updated application forms, rules for mid-year eligibility changes (prorating taxes based on days of eligibility), and simplified documentation for military homeowners. The bill does not alter the exemption's eligibility criteria but clarifies calculation methods and administrative processes for county assessors.
H 557 prevents Idaho cities and counties from creating local anti-discrimination laws that are stricter than state law. It specifically blocks local ordinances covering employment, housing, education, or public accommodations from expanding on state protections. Businesses or property owners can sue local governments that violate this rule, seeking court orders to stop enforcement and recover damages. The bill aims to create statewide consistency in anti-discrimination rules, arguing that varying local laws hinder economic growth and create legal conflicts for businesses. It takes effect on July 1, 2026.
