I have a California rental insured by Foremost as a four-family property, which is their maximum. One additional person rents a private bedroom/living area with:
Private attached bathroom
Private exterior entrance
Real, usable interior door connecting it to the main dwelling
No kitchen, kitchenette, stove, or permanent cooking facilities
No right to use the main kitchen
A room-rental agreement—not a studio or apartment lease
Here’s the problem:
If he’s a roomer: it remains a four-family property and is apparently eligible.
If his space is a separate living unit: it becomes a five-family property and Foremost won’t insure it.
The private entrance and bathroom say “unit.” The missing kitchen and interior connection say “room.” Which factors actually win in property underwriting?
If you were entering this risk, what would you put in the number of families/units field—and what carrier rule or definition would you rely on?
Has anyone seen Foremost, Farmers, or another DP3 carrier decide this exact configuration? I’m trying to disclose it correctly, not hide the occupant.

Adam — I think the missing kitchen is the biggest fact in your favor.
A private entrance and private bath make the space feel independent, but they don’t necessarily make it a separate dwelling unit.
California’s building-code definition of a dwelling unit generally requires complete independent living facilities, including permanent provisions for cooking. You don’t have that here. You also still have a real interior connection to the main dwelling.
So if I were looking at this purely from the physical configuration, I’d lean:
4-family property + 1 roomer, not 5 units.
But I would not rely on the building-code definition alone, because the carrier gets to define its own underwriting box.
Foremost publicly describes its landlord program as covering one-to-four-family dwellings. I also found Foremost underwriting guidance from another state that separately addresses roomers/boarders and says more than two can make a dwelling ineligible, while separately capping dwelling-fire risks at four family units. That’s useful because it shows Foremost itself can treat “roomers” and “family units” as two different underwriting concepts. It is not California-specific enough for me to tell you to rely on it as the final answer, though.
The municipality question above is worth checking, but I don’t think zoning alone answers the insurance question either.
What I would do is make the underwriter answer this exact fact pattern in writing before binding:
Then ask them one more thing:
If it is a roomer, is a four-family dwelling with one roomer eligible under the California Foremost landlord program?
That second question matters. You don’t want to win the “not a fifth unit” argument and then discover there is some separate California roomer limitation.
If Foremost confirms roomer treatment, I’d put 4 in number of families/units and separately disclose the roomer wherever the application gives you the opportunity.
I would not put 5 just because the guy has his own door and bathroom.
And I definitely wouldn’t try to solve this by changing what the lease is called. Underwriting is going to care about how the space is actually configured and occupied, not whether the heading says “room rental.”
Get the carrier’s classification in writing and staple it to the policy file.
That is the piece I’d want in my pocket if a claim ever turns this riddle into a much more expensive conversation.

I think the label matters less than what the application and dec page literally say, so get the carrier to state in writing which one they underwrote. The exposure is a denial later on misdescription, not the premium. His four facts are exactly what the underwriter weighs, send them in writing.
