L.A.’s lax enforcement of Airbnbs has led to an surge of illegal short-term rentals — even four years after the city passed a regulation to crack down on such practices. But what if hosts lived in a building that welcomed Airbnb guests and short-term rentals?

That’s the idea behind Airbnb’s new push to expand short-term rental offerings. The company is partnering with a number of corporate landlords that agreed to offer “Airbnb-friendly” apartment buildings, reported The Wall Street Journal last week. According to the report, the new service will feature more than 175 buildings managed by Equity Residential, Greystar Real Estate Partners LLC and 10 other companies that have agreed to clear more than 175 properties nationwide for short-term rentals.

But prospective hosts in Los Angeles who decide to rent apartments from Airbnb’s list of more than a dozen “friendly” buildings in the city likely won’t earn enough to break even due to a combination of high rents, taxes and city restrictions on short-term rentals. Rents on one-bedroom apartments in most of the partnered buildings listed soared well over $3,000 a month. Only a few studios were available under the $2,000 price range. If a host were to rent a one bedroom apartment with a monthly rent of $2,635 (which amounts to $31,656 annually), they would have to charge well over the $194 average price per night for Los Angeles (which amounts to $23,280 per year) according to analytics platform AllTheRooms.

Either way, residents who rent one of these Airbnb friendly apartments still have to apply for a permit through the City of Los Angeles in order to host on Airbnb.

“[..Airbnb-friendly buildings] seems like a good initiative. However, from a quick look, it seems that given the rent, Airbnb revenue wouldn’t be enough to cover all expenses if the host follows the city’s policy,” says Davide Proserpio, assistant professor of marketing at the USC Marshall School of Business.

In addition, since L.A.’s 120-day cap on short-term rentals still applies to the buildings on Airbnb’s listing platform, that greatly limits the number of longer-term guests a resident can host. Not to mention, some of the buildings that Airbnb lists have even shorter limits – The Milano Lofts in DTLA for example only allows residents to host 90 nights a year.

Airbnb’s calculations of host earnings may be greatly misleading as well, given that the estimate doesn’t include host expenses, taxes, cleaning fees or individual building restrictions. For example, Airbnb estimates that a resident of a $3,699 one bedroom apartment at the Vinz in Hollywood that hosts 7 nights a month can expect $1,108 a month in revenue if they host year-round. But the Vinz only allows hosts to rent 90 days a year, which greatly limits the potential for subletters and a consistent income stream.

Keep in mind too that since the apartment will have to serve as the host’s “primary residence”, hosts will have to live there six months out of the year. All of which is to say, it’s unclear how renting an apartment in an “Airbnb-friendly” building makes hosting easier — especially in a city where illegal short-term rentals already seem to be the norm.
