Austin, Texas, once a hotspot for price growth, now leads the nation in rent declines and ranks among the top cities for falling home prices as tech talent returns to the coasts.<\/p>\n<p>Hollie Conde, a fellow at think tank <strong>Sightline Institute<\/strong>, told <em>The Builder\u2019s Daily<\/em> that the scenario hasn\u2019t happened in Idaho.<\/p>\n<p>\u201cSo far, they have kept their jobs,\u201d Conde said. \u201cIt\u2019s come so far that we have people in the legislature that have lived here for five, six years.\u201d<\/p>\n<h2 class=\"wp-block-heading\">Solving a housing affordability problem<\/h2>\n<p>The new population brought big salaries and buying power that drove housing prices beyond what the average Idaho resident could afford.<\/p>\n<p>Mountain West cities led the 2025 <strong>Urban Land Institute<\/strong>\u2019s Terwilliger Center Home Attainability <a href=\"https:\/\/www.housingwire.com\/articles\/the-new-geography-of-the-u-s-new-home-affordability-crisis\/\">Index<\/a> with percentage increases in home prices, citing data from 2019 to 2023. Boise\u2019s metropolitan area topped the list, Coeur d\u2019Alene, Idaho Falls and Twin Falls in the Top 10.<\/p>\n<p>Last year, state lawmakers created a committee to study state and local land-use regulations and their impact on housing supply. The committee returned with recommendations, many of which are now law.<\/p>\n<p>As is typical in other states, local governments fought the changes and still aren\u2019t happy with the results. Coeur d\u2019Alene city officials called the bills \u201cdumb\u201d and \u201cnot very clever\u201d during a public meeting Tuesday, a local newspaper <a href=\"https:\/\/cdapress.com\/news\/2026\/apr\/14\/city-officials-frustrated-as-idaho-housing-laws-limit-local-authority\/\">reported<\/a>.<\/p>\n<h2 class=\"wp-block-heading\">Manufactured housing \u2014 H800<\/h2>\n<p>Idaho law now treats manufactured homes, including manufactured duplexes and other multi-dwelling units, similarly to site-built single-family and multifamily housing for siting purposes. It lowers minimum size requirements and clarifies that single-section and smaller units cannot be zoned out. <\/p>\n<p>Cities must allow manufactured single-unit homes wherever they permit single-family housing, while manufactured duplexes are limited to multifamily zones.<\/p>\n<h2 class=\"wp-block-heading\">Lot splits for ADUs \u2014 H707<\/h2>\n<p>Subdivision law now includes an administrative path for cities and counties to approve limited lot splits. The property must already have an existing or approved ADU or secondary unit, mainly to enable separate ownership or financing. <\/p>\n<p>The split does not add new dwelling entitlements or density beyond what zoning already allows and is \u201cone and done\u201d for the parent parcel. Each resulting lot must still meet local infrastructure, setback and building requirements.<\/p>\n<h2 class=\"wp-block-heading\">Single-stair \u2014 H706<\/h2>\n<p>Changes to the Idaho Building Code Act let local governments approve small apartment buildings with a single interior exit stairway. Those buildings must meet strict life-safety standards and are limited in height, unit count and floor area. They also must have full sprinklers, pressurized two-hour-rated stairs, fire-rated corridors, short exit travel distances and robust smoke and fire detection.<\/p>\n<h2 class=\"wp-block-heading\">ADUs \u2014 S1354<\/h2>\n<p>The zoning reform requires cities to allow accessory dwelling (ADUs) units by right as a residential use in many places. It prevents local governments and homeowners\u2019 associations from flatly banning ADUs. The law guarantees at least one ADU per lot in covered jurisdictions.<\/p>\n<p>It also bars local rules that impose hard maximum size caps, but still allows health, safety and infrastructure standards.<\/p>\n<h2 class=\"wp-block-heading\">Starter homes \/ small lots \u2014 S1352<\/h2>\n<p>State law now preempts certain local regulations to protect \u201cstarter home subdivisions\u201d on at least four acres. It prevents cities from banning these projects through large minimum lot sizes and other dimensional standards.<\/p>\n<p>The law bars local rules that require lots above a defined minimum size, such as 1,400 square feet, or impose certain setbacks, depths and fees. It also pushes cities to permit smaller lots and higher minimum densities, around 12 units per acre, subject to infrastructure limits, for these starter home projects.<\/p>","protected":false},"excerpt":{"rendered":"<p>Idaho Gov.
