Updating Local Regulations to Encourage More Accessory Dwelling Units - MRSC

The Municipal Research and Services Center (MRSC) continues to provide guidance to local governments on updating regulations to encourage accessory dwelling unit (ADU) development, offering free consultation services to eligible agencies through their Ask MRSC platform.

The organization connects local officials with attorneys and policy consultants to navigate the complex regulatory landscape surrounding ADU implementation and zoning modifications.

For California property owners and developers, streamlined ADU regulations represent significant opportunities to increase housing density and generate rental income on existing residential lots.

ADUs, also known as granny flats or in-law units, are secondary housing structures built on single-family residential properties and have become a key strategy for addressing California's housing shortage.

Recent state legislation has removed many local barriers to ADU construction, but municipalities still require technical assistance to align their zoning codes with new requirements.

The MRSC's educational resources address broader housing policy tools beyond ADUs, including inclusionary zoning programs that require or incentivize affordable housing in new developments.

These regulatory updates are particularly relevant for California developers who must navigate both state mandates and evolving local ordinances.

As communities work to implement housing-friendly policies, property owners may find expanded opportunities for small-scale development projects that were previously restricted by outdated zoning regulations.
