Rise of the ‘granny flat:’ New rules bring ADU boom to Sacramento area - Abridged �

Accessory Dwelling Unit construction has surged dramatically in the Sacramento area following recent changes to California laws and local regulations designed to address the state's housing shortage.

The city of Sacramento issued 1,134 ADU permits between 2020 and 2024, representing a nearly eight-fold increase compared to just 143 permits issued in the previous five-year period.

The boom reflects how streamlined regulations have made it easier for homeowners to add secondary living units to their properties, whether through garage conversions, backyard cottages, or other configurations.

These units serve multiple purposes for California families, from housing aging relatives and adult children to generating rental income in expensive housing markets.

One Land Park homeowner converted her garage into a 575-square-foot unit that has housed her in-laws during the pandemic and now provides affordable housing for her adult daughter while she saves money in Sacramento's challenging rental market.

The trend represents a significant opportunity for California property owners and developers as ADUs offer a way to increase housing density without major infrastructure changes.

For homeowners, the units provide flexibility to accommodate changing family needs while potentially creating income streams.

The regulatory changes have effectively unlocked thousands of potential housing units across the Sacramento region, contributing to efforts to address California's ongoing housing crisis through creative use of existing residential properties.
