California legislators re-try to ‘loophole-proof’ starter home law

California lawmakers are adding muscle to the state’s five-year-old starter home law to prevent cities and counties from quietly neutralizing it through local rules.

Senate Bill 1116, which passed the state Senate on May 20 without a single no vote, would strengthen the Starter Home Revitalization Act, a 2021 law requiring local governments to fast-track approvals for small-lot, for-sale detached homes.

The bill now heads to the California Assembly.

The bill underscores the frequent plight of legislation designed to lower barriers to building homes. Almost invariably, new laws to add housing supply require repeated legislative intervention to keep local governments from exploiting workarounds that delay or derail such projects.

Florida is a noteworthy example. State leaders amended the state’s 2023 Live Local Act for the third time this year. New Hampshire lawmakers are now revisiting a housing law passed last year.

Housing advocates say the pattern of amendments is not evidence of flawed laws. They argue it reflects the reality that state preemption of local zoning authority requires continuous revision when local governments treat each new restriction as a puzzle to be solved in reverse.

“It was a hard fight to get these laws passed,” Matt Lewis, California YIMBY’s director of communications, told The Builder’s Daily. “Now, they want to make sure they work.”

A changing law

The 37-0 vote was the latest step in what has become an iterative tug-of-war between state lawmakers and local governments over small ownership housing. California has struggled to produce this category of home as land costs, permitting delays and local design standards push developers toward rentals or larger, higher-margin projects.

California elected and appointed officials have tried to solve the housing affordability problem for years. Efforts accelerated during the COVID-19 pandemic as remote workers left the state for less expensive locales.

The original starter home law took effect in 2022. California is one of the rare states to pass starter home legislation – lawmakers in Colorado, Arizona, Minnesota, Utah, Kentucky and North Dakota failed to do so. Texas lawmakers largely succeeded last year.

California’s law required cities and counties to ministerially approve projects that subdivided multifamily-zoned lots into smaller parcels for detached starter homes. It bypassed California Environmental Quality Act review entirely and stripped local agencies of discretion to deny qualifying applications except on narrow public health and safety grounds.

But lawmakers quickly discovered the law was difficult to use. Cities interpreted the approval pathway inconsistently. Developers faced ambiguity over which map processes applied.

Lawmakers responded in 2023 with SB 684, which formalized subdivision map procedures, codified 60-day approval deadlines and confirmed that denial required a written finding.

Then came SB 1123 in September 2024, which expanded the law’s reach to vacant single-family-zoned lots up to 1.5 acres — the first time the starter home framework crossed into single-family zoning. It also recognized tenancy in common and community land trusts as eligible ownership structures.

New law makes technical changes

Even then, local resistance persisted. The state Department of Housing and Community Development issued technical assistance letters in early 2025 rebuking Oakland and Hayward for imposing prohibited standards.

Oakland required conditional use permits for qualifying projects and enforced setback and open-space rules that effectively thwarted construction. Hayward improperly limited the law’s application to sites zoned exclusively for multifamily use, rather than to any zone that allows it.

SB 1116’s summary identified that pattern as a widespread problem. Cities and counties have imposed height, setback and lot-size rules that shrink unit counts or kill projects outright.

“Ambiguity in eligibility standards and inconsistent local implementation have further limited the law’s impact,” the summary added.

The bill is a direct response. It requires building height to be measured in physical feet rather than stories, closing a documented local workaround. The bill further restricts front and internal setback requirements and mandates that the law be interpreted liberally to maximize unit production.

It also requires local governments adopting ordinances under the starter home law to submit them to the California Department of Housing and Community Development for compliance review. The formal enforcement checkpoint that did not previously exist. SB 1116 also revises the definition of “vacant” and updates site-eligibility tests cities and counties have used to disqualify parcels the legislature intended to capture.

The Assembly path could be smooth, according to Lewis.

“It’s clean-up legislation,” he said.

Passage alone may not erase “not-in-my-backyard” influence over local officials.

“Most California cities are still over-indexing on residents who oppose all housing,” Lewis said.
