LA's ADU Ordinance Rewrite Puts STR Hosts on Notice

Los Angeles just moved one step closer to rewriting the rules that govern accessory dwelling units, and if you are hosting short-term guests in an ADU, the direction of travel is not in your favor. The city released a second draft of its proposed ADU Ordinance in September 2026 as part of the Missing Middle LA initiative, and a staff-level public hearing is already on the calendar for October 1, 2026. The ordinance is not final yet, but the shape of what is coming is clear enough to act on now.

What the Draft Ordinance Actually Says

The September draft is a proposal, not a done deal. According to the source, City Planning describes it as intended "in part to bring the City's 2019 ADU regulations into alignment with current state law." That alignment with state law is the key phrase for STR hosts, because California's updated state framework is already stricter than many hosts realize.

California's Department of Housing and Community Development updated its ADU Handbook in March 2026 to incorporate legislative changes. One of the most direct hits for short-term rental operators: Junior ADUs, known as JADUs, may no longer be used as short-term rentals. When rented, JADUs must be rented for periods longer than 30 days. If you have been running a JADU as a nightly or weekly rental, that use is now off the table under state guidance, regardless of what the final city ordinance says.

The Hearing Date That Matters

City Planning has scheduled a staff-level public hearing on the Missing Middle LA proposals for October 1, 2026. That is the first formal checkpoint where the draft can be shaped, challenged, or advanced. Hosts who want to weigh in have a narrow window. After that hearing, the ordinance moves further along the adoption track, and the rules currently proposed become harder to change.

The source is explicit that "the September ordinance remains a proposal rather than a final adopted ordinance," so nothing has been locked in yet. But waiting for finalization before adjusting your operation is a gamble, especially given how aggressively the city already enforces its existing STR rules.

What the Current Rules Already Require

Even before this new ordinance lands, Los Angeles operates one of the strictest short-term rental regimes in the country. Under the existing Home-Sharing Ordinance, unhosted stays are capped at 120 nights per calendar year. The property must be your primary residence. Fines for violations run up to $2,000 per day, and the city enforces actively, having removed thousands of non-compliant listings from platforms in recent years.

The local accommodation tax rate sits at 12 percent, filed monthly, with a deadline on the 30th of each month. Tax submission is manual, meaning you are responsible for filing yourself through the city's portal. Signage and a fire extinguisher are required on-site. These are not new requirements, but they are the baseline every host must already be meeting while the new ordinance works its way through the process.

ADUs built after January 1, 2017 face an additional constraint under existing rules: they can only be used for home-sharing if the ADU itself is your primary residence. The incoming ordinance, if adopted, would layer additional state-aligned restrictions on top of that.

What Hosts Should Do Right Now

The practical advice here is straightforward. If you operate a JADU as a short-term rental, the state guidance effective in 2026 already prohibits that use. Stop now, not when the city ordinance is finalized. If you operate a detached or attached ADU, verify whether it qualifies under the primary-residence rule and confirm your registration is current.

The source puts it plainly: homeowners should "distinguish between rules currently in effect and proposed changes that are still moving through the public review and adoption process." That discipline matters for hosts too. The JADU short-term rental ban is current state law. The broader ADU ordinance rewrite is still proposed. Know which category each rule falls into before you make any changes to your listing.

The October 1 hearing is a real deadline. If you want to participate in shaping the final ordinance, that is your moment. If you simply want to stay compliant, audit your ADU's status against both the existing city rules and the updated state guidance before that date arrives.
