SAN FRANCISCO (KTVU) - Tuesday is Election Day in the Bay Area.
Housing is definitely a major issue on the ballot in San Francisco.
One of the most contentious measures gaining national attention is proposition F.
Just Monday, supporters of proposition F demonstrated at the headquarters of Airbnb.
The vacation rental company has spent more than $8 million to fight the measure.
If passed, it would limit short-term rentals to 75 days a year and prohibit the use of in-law units as short term vacation rentals.
It would also require quarterly reports to the city on how the unit is being used.
Airbnb says it did not create San Francisco's housing crunch, nor the sky-high rents.
But tenants rights groups say something has to be done to prevent the conversion of permanent rental units to vacation rentals.
San Francisco's elections director expects more than 50 percent of votes to be cast by mail-in ballots.
