Short-term corporate housing in Silicon Valley: the 30-night line

When a mobility manager asks me for "short-term corporate housing" in Sunnyvale or Santa Clara, they usually mean three or four weeks. That request lands right on a line most housing budgets don't account for. In California, a stay of 30 nights or fewer is one kind of occupancy and 31 or more is another. The difference shows up on the invoice as a tax line, and it changes which units you can legally book and what rights your employee has once they've moved in.

What changes after night 30

Start with state law, because every city's rules hang off it.

Section 7280 of the Revenue and Taxation Code lets a city tax lodging "unless the occupancy is for a period of more than 30 days." That's the authority behind every hotel tax in the region, and it's why a furnished stay of 30 nights or fewer gets taxed like a hotel room.

Civil Code Section 1940 then carves those taxable stays out of California's landlord-tenant chapter. Once a stay is past the taxable window, the person living there is generally covered by that chapter like any other renter. Deposit rules apply. Notice rules apply. Getting someone out who won't leave goes through the courts.

The cities draw their short-term rental ordinances on the same line. San José's zoning code defines a transient user as anyone staying 30 consecutive days or less. Redwood City says outright that stays of 30 nights or more aren't subject to its short-term rental rules or its hotel tax.

The tax, city by city

These are the hotel tax rates on a stay of 30 nights or fewer in the cities where most of our placements land, checked against each city's own page or code this month.

San José's rate went up two points on October 1, when Measure A raised the general-fund share. Any 2027 budget built from last year's invoices is understated there. Santa Clara's rate rose from 12.5% to 13.5% at the start of 2025. Palo Alto's is the highest on the list.

None of that applies to a stay of 31 nights or more. Usually.

Santa Clara wants the paperwork before move-in

This is the detail I'd flag first for anyone booking into Santa Clara.

Santa Clara's code treats a guest as transient, and taxable, until 30 consecutive days have passed. The tax stops on day 31. To be exempt from the first night, the occupant has to sign a written agreement with the operator before moving in that commits them to pay market rate for at least 31 consecutive days. The city's finance department publishes a sample agreement.

So two placements of the same length can be taxed differently. An employee booked for 60 nights on a signed 60-night agreement pays no hotel tax. An employee booked for three weeks and extended to 60 nights pays 13.5% on the first 30. On a $7,000 month, that's $945 lost to the order the paperwork happened in.

San José's definition also looks at the agreement. A transient is someone who stays, or is entitled to stay, under an arrangement of 30 consecutive days or less. If you know an assignment runs past a month, book it past a month from the start and negotiate the early-release terms instead. I covered how those cancellation terms work separately.

Short stays come from a capped pool

The inventory changes under 31 nights too. A lot of furnished units offered for two or three weeks are short-term rentals, and in this region those run under city caps when the host isn't living there:

• Mountain View and Cupertino: 60 unhosted nights a year
• Santa Clara: 90
• San José: 180
• Sunnyvale: none, because the host has to live on site

Those are calendar-year limits. A Mountain View host who's already used 60 unhosted nights can't legally take your November booking, whatever the listing calendar shows. Cupertino requires the platforms to block listings without a valid city registration number, and Sunnyvale requires the approval number in the ad. Asking a provider for the city registration number takes thirty seconds and tells you whether the unit is legal for the stay.

It's also part of why the per-night rate on a short booking runs higher. The regulatory wrapper is one of the three drivers in the stay-length cost curve, and it's why the 30-day price sits at the top of it.

Past 30 nights, treat it as a lease

Once a stay crosses the line, the law mostly treats it as a tenancy, and you should too.

That matters most when something goes wrong. If an employee leaves the company in week six and doesn't move out, nobody gets to change the locks. Ending the occupancy runs through the same legal process as any other tenancy, and whose name is on the agreement decides who has to start it. That's one reason company-held agreements are cleaner, and I went through the employer's side of that liability in more detail.

It changes the deposit conversation as well. The deposit statute caps security at one month's rent in most cases, with no higher allowance for furnished units. If a provider asks for two months on a furnished 90-day stay, ask them which exception they're relying on.

What I'd do with a 2027 placement plan

If the assignment is 31 nights or longer, book it that way on day one, sign before move-in, and put your negotiating energy into early release. If it's three weeks and will stay three weeks, budget the hotel tax by city from the table above and ask for the city registration number. If it could go either way, plan for the longer stay. Booking a 60-night assignment as 30 nights and extending is the expensive mistake.
