17 Findings: HCD Faults L.A.'s ADU Ordinance, Line by Line

You're a homeowner or a designer trying to build an ADU in the City of Los Angeles. You open the municipal code to check the rules — the size, the height, the setbacks, the timeline — and you assume the biggest planning department in the state has its ordinance squared with state law.

Here's the thing: HCD reviewed L.A.'s ADU ordinance and found it out of step with State ADU Law in seventeen separate places — everything from citing statutes that no longer exist to a "60-day" clock that isn't the one the law actually gives you. That's HCD's read, not a court's ruling. But it's a map of exactly where a local ADU rule can quietly diverge from the state floor.

What HCD reviewed

On November 19, 2024, HCD sent written findings to the Los Angeles Department of City Planning on the City's ADU Ordinance No. 186481 (passed December 11, 2019; effective December 19, 2019), read together with Zoning Administrator Memo 142. HCD reviewed it under State ADU Law (Gov. Code §§ 66310–66342) and issued the findings pursuant to Gov. Code section 66326. Its conclusion, in HCD's own words:

the Ordinance and Memorandum do not comply with State ADU Law in the following respects

Then came a numbered list — Finding 1 through Finding 17.

Verified against HCD's ADU Ordinance Findings letter to the City of Los Angeles (Ordinance No. 186481), dated November 19, 2024.

Five of the seventeen you'd feel at the counter

• Dead statute numbers (Finding 1). HCD found the ordinance still points to "Government Code sections 65852.2, 65852.22 and 65852.26" — sections "deleted by SB 477, effective March 25, 2024," and moved to §§ 66310–66342. Look them up as written and you're reading code that isn't there anymore.
• The "acted upon" clock (Finding 3). The ordinance says an ADU application "shall be acted upon within 60 days." HCD's position: Gov. Code section 66317 requires the agency to "either approve or deny" the application in that window — a decision, not just movement on the file.
• A 16-foot height cap (Finding 9). The ordinance limits certain detached ADUs to "a height of no more than 16 feet." HCD found state law allows 18 feet near transit, and up to 20 feet to match the primary home's roof pitch.
• Fees on small ADUs (Finding 14). The ordinance sweeps ADUs into its park land-dedication and fee requirement. HCD found Gov. Code section 66324 bars impact fees on ADUs "less than 750 square feet," with larger ADUs charged only proportionately.
• An owner-occupancy rule (Finding 16). HCD found that Assembly Bill 976 prevents jurisdictions "from imposing owner-occupancy requirements on ADUs as of January 1, 2024."

That's five. The other twelve run through a fire-zone prohibition, a two-story limit on detached ADUs, the conversion of detached accessory structures, counting ADUs toward density, separate-conveyance exceptions, building-code-violation protections, and the JADU separate-entrance rule.

Why the whole-ordinance story matters

This isn't one stray clause. If the largest, best-resourced planning department in California can carry seventeen mismatches at once — years after the underlying statutes changed — the ordinance at your counter can drift too. HCD's findings read like a checklist of where local ADU rules tend to fall behind the state floor: height, fees, timelines, unit counts.

And it's worth being precise about what the letter is. An HCD findings letter is HCD's interpretation and enforcement position — not settled law. Courts are the final arbiter. HCD gave the City two paths: amend the ordinance, or adopt it unchanged with findings explaining why it complies "despite HCD's findings." If the City did neither, HCD said it "may notify the California Office of the Attorney General."

So if a Los Angeles ADU rule seems to block something state law appears to allow — a height, a fee, a second unit, a 60-day answer — it's worth raising. But confirm the current ordinance language and your specific situation with the City and your own counsel before you rely on any of it. This isn't legal advice.
