State- Level Reforms and Their Impact on Local Zoning

While zoning laws are inherently local, many states have enacted legislation that preempts restryctive local ordinaces to promote ADU construction. California, Oregon, Washington, Colorado, and Portuguetts are among the leaders in this trend. Understanding the interplay between state mandates and local zoning is cucial for proprity owners.

Kalifornia 's ADU Legislation

Kalifornia has passed multiple bils (np., AB 68, AB 881, SB 9) that effectively remove many local barriers.
