California rental market bucks national trend, sees decline in major cities
While national rental rates climbed in mid-2024, seven of eleven major California cities reported year-over-year rent declines for one-bedroom apartments. The steepest rent drops were recorded in Oakland and Sacramento, driven by population outflows and shifting economic demand rather than major supply increases.
1 of every 5 new homes built in California last year was an ADU
Accessory dwelling units accounted for roughly 20 percent of all new residential construction across California in 2023, up significantly from one in ten units three years prior. Homeowners are increasingly turning to backyard units to house multigenerational family members and alleviate housing affordability pressures.
One of every five new homes built in California last year was an ADU
Statewide data reveals that backyard homes represent an expanding share of California's newly completed residential supply. Developers and property owners are taking advantage of recent state laws that streamline approval processes and lower permitting hurdles.
What is the new California ADU Law?
This legal analysis outlines key legislative updates taking effect in California, including AB 1033 which allows local jurisdictions to permit separate condominium sales of ADUs. It also details AB 976, which permanently removes owner-occupancy requirements for constructing rental ADUs.
California ADU Laws Expected To Boost Affordable Inventory
Industry analysts examine how recent California legislation such as AB 1033, AB 976, and AB 1332 are facilitating faster permitting and pre-approved plans for backyard homes. Mortgage lenders and developers see these laws as critical mechanisms to inject affordable housing inventory into high-cost suburban markets.
California ADU Reform: A Retrospective
A comprehensive retrospective details how statewide ADU legislation enacted since 2016 led to an over 15,000 percent increase in annual permitting over six years. The report highlights how accessory units have grown to represent nearly a fifth of all newly permitted homes in California.
ADU grants resume to help low-income Californians build
California reopened state grant funding through CalHFA to help lower-income homeowners cover pre-development and permitting costs for accessory dwelling units. The program provides up to $40,000 per project to offset expenses like architectural design, site surveys, and utility fees.
California’s first ADU condo sale offers another path to homeownership
Following the adoption of AB 1033, the first detached ADU sold separately as a condominium unit closed in San Jose. The transaction demonstrates a novel mechanism enabling entry-level homeownership in expensive metropolitan regions without purchasing primary parcels.
ADU Grant Program
CalHFA provides formal guidelines on its state-backed initiative offering pre-development financing support of up to $40,000 to eligible California homeowners building secondary units. The program aims to increase rental supply while promoting wealth creation among lower-to-moderate-income families.
Accessory Dwelling Units
The California Department of Housing and Community Development maintains regulatory oversight, model ordinances, and technical compliance letters for ADU production statewide. The department assists local governments in updating local zoning codes to meet mandatory state housing standards.
ADUs can now be sold separately in California
New statutory updates permit local municipalities to pass ordinances allowing homeowners to sell accessory units as standalone condominiums. The shift is projected to create lower-priced homeownership opportunities and open new lending options for private mortgage originators.
