Two new Idaho bills aim to boost 'starter home' development and housing supply. 

As Tristan Navera explains on Realtor.com, SB 1352 requires local governments to allow lot sizes as small as 1,400 square feet, the first state to do so, and removes some zoning barriers like setback requirements. SB 1354 bars local governments and HOAs from restricting accessory dwelling units, guaranteeing the right to build at least one ADU per lot. "Republican Rep. Erin Bingham said it bolsters local property rights and increases housing inventory. Existing HOA bans can remain in effect, and cities will be able to opt out." Both bills apply to cities over 10,000 people.

A bill that would allow the construction of single-staircase buildings advanced to the governor's desk.
