The Impact of Airbnb and Short-Term Rentals on San Mateo’s Rental Market

Have you noticed that the San Mateo market has been flooded with short-term rentals and Airbnbs? 

We have some regulations and licensing requirements in place to limit the number of short-term rentals in our community, but they’re still having a pretty dramatic impact on the rental market as a whole. Let’s talk about what that means for you.

Our Overview: Less inventory in the rental market could be due to many investment properties becoming short-term rentals rather than long-term leases. Lower inventory means more demand and higher rents for long-term properties. Some communities have pushed back against short-term rentals in their neighborhoods. Investors now must decide whether to use properties for short-term or long-term rentals.

Short-Term Rental Growth in San Mateo

San Mateo has experienced a noticeable increase in short-term rentals such as Airbnb listings in recent years due to a combination of economic, geographic, and market-driven factors. Our specific market makes this kind of expansion understandable.

• One of the primary reasons is strong financial incentive. Homeowners in San Mateo operate within one of the most expensive housing markets in the country. Property values are high, and so are mortgage payments, property taxes, and maintenance costs. Short-term rentals have the potential to generate significantly more income per night than traditional long-term leases. For many owners, listing on Airbnb provides a flexible way to offset housing expenses or maximize returns on investment properties.
• Location also plays a major role. San Mateo sits between San Francisco and Silicon Valley, making it an attractive base for both business and leisure travelers. Visitors attending tech conferences, corporate meetings, or extended work assignments often prefer the comfort and space of a home rental over a hotel. At the same time, tourists appreciate staying in a quieter residential area while remaining close to major attractions throughout the Bay Area. This steady flow of visitors creates consistent demand for short-term accommodations.
• Changing travel preferences have further contributed to growth. Many travelers now seek unique, neighborhood-based experiences rather than traditional hotel stays. Remote work trends have also increased demand for longer short-term stays, with guests booking weeks at a time.

While local rules attempt to limit or manage short-term rentals, enforcement can be challenging. 

San Mateo Short-Term Rental Regulation 

Short-term rentals in San Mateo, CA, require registration with the city, the procurement of a valid business license, and compliance with a 14% Transient Occupancy Tax (TOT) for stays under 30 days. Hosts must register their rental and obtain a business tax certificate from the City of San Mateo. To register, a fee of $250 must be paid by July 1 of every year that the short-term rental is operated.

Owners are required to follow specific safety standards and noise limits. And, at least one parking space must be provided. In the unincorporated Coastal Zone, rentals are limited to 180 days per year and are not allowed in ADUs. 

What Do Short-Term Rentals Mean for the Larger San Mateo Rental Market?

The rental market has been impacted not only from a regulatory standpoint, but in terms of economic ripple effects, neighborhood dynamics, housing availability, and long-term investment strategies. 

1. Shifts in Housing Supply and Availability

One of the most direct impacts of short-term rentals on the San Mateo rental market is the reduction in the supply of long-term rental units. When property owners convert units that could otherwise be leased to residents into short-term stays for tourists or temporary workers, the pool of housing available for long-term renters shrinks. 

For renters seeking housing in San Mateo, a smaller supply means fewer choices and greater competition. In an already tight housing market with high demand, losing even a modest number of units to short-term use can contribute to upward pressure on rents. That means higher rental values for owners, which is good, but long-term renters may find themselves facing fewer affordable options and longer search times.

2. Upward Pressure on Rents

Closely tied to reduced availability is the impact on rental pricing. When long-term apartments and homes are converted into short-term rentals, the remaining inventory becomes more valuable to prospective residents. For San Mateo, a city known for its proximity to major employment hubs and desirable quality of life, rents are already considered high. With short-term rentals in the market and long-term rentals harder to find, prices rise. 

For property owners, the rising rent environment means stable income. But, higher rents can displace long-standing residents, alter the socioeconomic fabric of neighborhoods, and create friction between property owners and the local tenant pool which may struggle to find affordable housing close to where they work.

3. Neighborhood Character and Community Stability

Short-term rentals can subtly reshape the character of neighborhoods. Whereas long-term tenants tend to invest in their communities, form social ties, and support local businesses consistently, short-term guests are transient by nature. Frequent turnover of occupants can undermine the sense of continuity that long-term residents expect in their neighborhoods.

This has inspired some backlash against short-term rental housing in general. Long-term residents do not love the increase in foot traffic, unfamiliar faces, and inconsistent patterns. While many visitors are respectful and contribute positively to the local economy, the constant rotation can result in a sense of impermanence.

4. Impact on Long-Term Investment and Property Strategies

For rental property owners in San Mateo, short-term platforms have introduced a compelling economic question: is it more profitable to operate a property as a long-term rental or as a short-term stay? In many cases, short-term rentals yield higher gross revenue, especially during peak seasons or in units with desirable features and locations. This has led some investors to pivot their strategies toward short-term models.

However, this shift alters the long-term stability of investment portfolios. Short-term rentals can require more active management, frequent maintenance, higher utility costs (when included), and marketing efforts to maintain consistent occupancy. By contrast, long-term rentals offer predictable cash flow, lower turnover costs, and often fewer management headaches. Owners who shift heavily into short-term models may find their income fluctuates more with tourism cycles or broader travel trends, introducing volatility into what might otherwise be a stable investment.

5. Pressure on Affordable and Workforce Housing

The proliferation of short-term rentals in markets like San Mateo can have a disproportionate impact on affordable and workforce housing segments. These are units that would most often be rented to essential workers, young professionals, families, and others who contribute to the local economy but may not have high income levels.

When a portion of these rentals is repurposed for short-term visitors, who are often willing to pay premium nightly rates, the result is a reduction in housing accessible to full-time residents who need affordable rental options. The displacement of such homes can contribute to a scenario where workers in schools, healthcare, hospitality, and retail are priced out of the communities they serve, leading to longer commutes, increased traffic pressure, and challenges for local businesses trying to hire employees who live nearby.

6. Tourism Revenue vs. Local Service Economy

Short-term rental guests contribute to San Mateo’s local economy. They spend money at restaurants, shops, and entertainment venues. This inflow of tourism dollars can benefit small business owners and support local jobs. However, because these visitors do not live in the community full time, their economic contributions are intermittent rather than sustained.

For rental property owners considering the broader ecosystem, this creates a trade-off. The short-term rental market can stimulate certain sectors of the economy while simultaneously limiting the availability of housing for workers who support those very businesses on a daily basis. For example, a waiter or barista who cannot find affordable housing nearby may be unable to work at the restaurant that benefits from short-term guest spending.

7. Market Signaling and Future Development

The prevalence of short-term rentals sends signals to developers, investors, and policymakers about where demand lies. A strong short-term rental market can encourage real estate investment geared toward vacation or flexible stay accommodations. Developers may prioritize properties that cater to this segment, sometimes at the expense of traditional multifamily housing projects.

This shift in development focus can have long-term repercussions. If future housing is increasingly designed for short stays rather than long-term residency, the imbalance between supply and demand for everyday housing could worsen. In the long run, this affects rental property owners too; a market with fewer families and full-time residents may be less stable and more sensitive to shifts in travel trends and economic cycles.

This is a trend that we’re following, as San Mateo property managers. There is always going to be demand for both short-term and long-term rental housing in our market. As an investor, your long-term property will continue to attract good tenants and high rents, even as short-term and Airbnb rentals continue to show up.

There’s more to talk about here, and we’d love to bring our thoughts to your specific situation and portfolio. Understanding these dynamics and the benefits as well as the challenges helps rental property owners make informed decisions about how to position their assets and contribute to a balanced housing ecosystem that supports both visitors and residents.
