Ambulatory health care spans 26,872 LA County establishments — physicians and dentists at one end, and physical therapy, chiropractic, optometry, imaging, urgent care and home health at the other, where retirement plan coverage is far thinner. For those allied-health practices the mandate is often the first retirement conversation, and the answer turns on the census: heavy part-time and per-diem staffing rewards careful eligibility design, and the SECURE 2.0 startup credits may cover most of a first plan's early administration. Physician and dental owners have their own pages, linked below.
Why this industry is different
The mandate treats every employer alike. The payroll realities underneath don't cooperate:
- Part-time and per-diem staffing is the operating model — therapists, techs, aides and home-health staff on variable hours make eligibility tracking the central administrative problem.
- Coverage is lopsided inside the sector: physician and dental offices mostly have plans; PT, chiro, optometry and home health mostly do not — and they are exactly who the mandate now reaches.
- Owners are clinicians first — treating patients all day leaves no bandwidth for plan administration, so anything adopted has to run off payroll automatically.
- Home health agencies carry large, dispersed W-2 rosters of caregivers whose hours swing week to week — a census that punishes sloppy plan design.
- Multi-entity operators (a clinic here, an imaging center there) trip controlled-group rules they have never heard of.
What actually works
For an allied-health practice adopting its first plan, the design lever is eligibility: a one-year, 1,000-hour requirement keeps short-tenure and low-hour staff out of the census (subject to the long-term part-time rules), while automatic enrollment for those who do qualify keeps participation — and the plan's testing profile — healthy. Whether to add a safe harbor contribution depends on what the owner earns and wants to defer: an owner above the Roth IRA income limits (roughly $168,000 single / $252,000 married MAGI for 2026) cannot meaningfully use CalSavers, which is a Roth IRA underneath, and that alone often decides the comparison.
For a small clinic with modest owner income and a handful of staff, CalSavers may genuinely be enough — we will say so when the arithmetic says so. Physician and dental practices, whose problems are testing and contribution room rather than first-time adoption, should start from their own pages: physicians · dental.
The SECURE 2.0 credits frequently cover most of the first three years' administration for employers under 50 staff — the formula, worked honestly — and if after the arithmetic CalSavers is still the right answer for your shop, we'll say so: the full comparison · run your own numbers.

Ambulatory Health Care questions
Our therapists and aides work variable hours. Who actually has to be covered?
For CalSavers: essentially every W-2 employee 18 or older. For a private 401(k): whoever meets your eligibility conditions — commonly one year and 1,000 hours — plus long-term part-time employees with consecutive 500-hour years, who must be allowed to defer. The census review is annual, not one-time.
We run a home health agency with 40 caregivers. Isn't a plan unaffordable?
A plan's employer cost is a design choice — a deferral-only 401(k) has no required match, and CalSavers has no employer contribution at all. The real costs are administration and time, and the SECURE 2.0 startup credit may offset much of the administration for employers under 50 staff in the first three years. The arithmetic is worth running before assuming.
The clinic and the imaging center are separate LLCs with the same owners. Separate plans?
Common ownership likely makes them a controlled group, which means they are generally treated as one employer for coverage and testing — and for the mandate's headcount. This is one of the most frequent surprises in multi-entity health care and worth resolving before adopting anything.
How does this page relate to the dental and physician pages?
NAICS 621 is the parent sector — the 26,872 figure includes physician, dental and allied-health offices together, so the sub-sector pages deliberately do not quote separate counts. Use this page for PT, chiro, optometry, imaging, urgent care and home health; use the physician and dental pages for owner-contribution and testing questions.
