Palo Alto has never adopted a short-term rental ordinance of the kind many California cities use, with permits, caps and host registration. Instead, its position rests on older parts of the municipal code: the zoning definitions and the hotel tax. Read together, they produce a simple working rule for homeowners. Rentals of 30 days or more are ordinary rentals. Rentals of less than 30 days in a home are, in the city's own words, not permitted in almost all residential zones.
This page sets out those rules for owners, landlords and anyone thinking about hosting. It is general information, not legal or tax advice. The city has studied changes more than once, so confirm the current position with Planning and Development Services before you list a property. If you are a guest looking for a place to stay, our vacation rentals guide is written for you.
The zoning rule and where it comes from
The clearest statement is a staff report for a March 9, 2015 City Council study session on short-term rentals and home occupations. Staff explained the reasoning this way:
- The single-family and low-density residential zones (R-1, R-E, R-2 and RMD) allow residential uses and home occupations that are accessory to them.
- The zoning code defines a dwelling unit as one occupied or intended for occupancy "on a nontransient basis," in section 18.04.030.
- Home occupations must stay incidental to the residential use and must not create much more traffic or parking demand than a home normally does.
From those definitions, staff concluded that transient rentals of homes or bedrooms were not permitted. The report said "short term rentals of dwelling units or bedrooms for less than 30 days are currently prohibited in Palo Alto." It also noted that the code was written before the "shared economy" and might need clarifying changes.
The council took no action in 2015. Staff had laid out two models from other cities: an owner-occupied "homestay" permit like San Luis Obispo's and a registration system like San Francisco's. Neither was adopted. In December 2022 the council voted to ask its Policy and Services Committee to recommend how to update and enforce the 30-day rule, citing the housing shortage, according to the Palo Alto Daily Post. We found no newer short-term rental ordinance on the city's website in November 2026.
The hotel tax still applies
Separately from zoning, Palo Alto taxes short stays. Chapter 2.33 of the municipal code sets the transient occupancy tax.
| Rule | What the code says |
|---|---|
| Rate | 15.5 percent of the rent paid by the transient (section 2.33.020) |
| Transient | Anyone with occupancy rights for 30 consecutive days or less; part of a day counts as a day (section 2.33.010) |
| Registration | Operators apply for a Transient Occupancy Registration Certificate within 10 days of starting business and post it on site (section 2.33.050) |
| Rental agents | A third party that collects rent from a transient can collect and remit the tax (sections 2.33.010 and 2.33.140) |
The 2015 staff report said the tax applies to anyone renting accommodations short term, even when the rental violates zoning. Operators may also be audited. Paying the tax does not make an otherwise barred rental legal. Local reporting in 2022 described an agreement under which Airbnb collects the tax on bookings in the city. Hosts on other platforms, or hosts who take direct bookings, should not assume anyone is collecting it for them.
Backyard units and SB 9 homes
Accessory dwelling units are the most common way Palo Alto owners add a rentable space. The city's 2025 ADU and JADU guidebook requires ADU and junior ADU rentals to be for 30 days or more. State law lets cities set that minimum. Units built under SB 9, the state law that allows two homes on many single-family lots or a split into two lots, cannot be used as short-term rentals either. Our ADU and SB 9 guide covers the building rules.
A legal ADU rented for a month or longer is an ordinary rental. That brings landlord duties: Palo Alto's one-year lease offer rule, deposit limits and, for many units, state just cause rules. Our tenant protections page explains them.
Other limits owners run into
- Homeowner associations. Under California law, an HOA generally cannot ban all rentals, but it can prohibit rentals of 30 days or less. Read your CC&Rs. Our condo and townhome guide explains how associations work.
- BMR homes. Below Market Rate homes must be owner-occupied and carry rental restrictions. Short-term hosting is not an option. See our below market rate guide.
- Tenants. Most leases bar subletting without the landlord's written consent. A renter who hosts short stays risks the lease as well as the city rules.
- Insurance and lenders. Standard homeowner policies often exclude business activity. Ask your insurer and check your mortgage terms before hosting paying guests. Our home insurance guide covers coverage in Palo Alto.
- Hotels and commercial zones. Hotels operate in commercial zones under their own permits. The 30-day rule discussed here is about homes in residential zones.
What owners can do
The rules leave several options open.
- Rent for 30 days or more. Furnished monthly rentals to visiting scholars, hospital families, interns and relocating employees are common. Our intern and student housing page describes that demand.
- Take a long-term lodger. Renting a room to someone who stays for months is a normal tenancy. Use a written agreement.
- Swap or lend your home. Unpaid house-sitting and home exchanges are not rentals, though your insurer may still want to know.
- Ask the city first. If your situation is unusual, ask the planner on duty before you advertise.
Good to know
- The 30-day line appears in two places that use slightly different wording: the tax code says 30 days or less, while staff described the zoning bar as under 30 days.
- Enforcement has been mainly complaint-driven, but complaints, tax audits and HOA action can all lead to penalties.
- State law gives tenants protections once a stay becomes a tenancy. Plan exits and notices accordingly.
- Neighbors can report suspected violations through Palo Alto 311.
How enforcement works
In 2015 the city had two code enforcement officers for building and zoning cases, with some support from the City Attorney's office. Staff described enforcement as largely complaint-driven. Over the 18 months before that report, staff had received seven complaints tied to short-term rentals or related home occupations and had resolved most of them. Staff also said a full inventory was hard because listings often hide addresses. A 2015 estimate cited in the report put the number of Airbnb listings in Palo Alto at three to four hundred, a figure staff had not verified.
The 2022 council referral suggested more interest in enforcement, partly to return homes to the long-term rental market. Owners should not read a quiet street as permission. A single complaint from a neighbor can start an investigation. Hotel tax audits can reach back over past bookings.
Nearby cities set their own rules
Each city decides its own approach. Mountain View, Menlo Park, Los Altos and East Palo Alto have their own rules, some with permits and some with outright bans. A rule that applies across the city line does not apply in Palo Alto. The reverse is true too. Check the city where the property sits. Our nearby towns hub introduces each one.
Frequently asked questions
Is Airbnb legal in Palo Alto?
For stays under 30 days in a home, generally not in residential zones. A 2015 city staff report said short-term rentals of dwelling units or bedrooms for less than 30 days were prohibited in almost all residential zones under the zoning code. Rentals of 30 days or more are ordinary tenancies.
Does Palo Alto have a short-term rental permit?
We did not find one. In 2015 the council chose not to create a permit program. In December 2022 it asked a committee to recommend how to update and enforce the 30-day rule, according to local reporting. We found no newer ordinance on the city's site in November 2026.
Do short-term rental hosts in Palo Alto have to pay hotel tax?
The city's transient occupancy tax of 15.5 percent applies to stays of 30 consecutive days or less. Staff said in 2015 that it applies even when the rental breaks zoning rules. Operators must register within ten days of starting business. Rental agents that collect rent also have collection duties.
Can I rent my ADU on Airbnb in Palo Alto?
Not for short stays. Palo Alto's 2025 ADU guidebook requires ADU and junior ADU rentals to be for 30 days or more. Units created through SB 9 lot splits or two-unit projects cannot be used as short-term rentals either.
What happens if a neighbor complains about a short-term rental?
City staff described enforcement in 2015 as largely complaint-driven, handled by code enforcement officers. A complaint can lead to an investigation and an order to stop. Owners can also face tax audits for unpaid hotel tax.
