Historically, the Tahoe Basin has seen a high rate of second home ownership, from about half to nearly two-thirds of the housing stock depending on the County. Based on more current data, these rates have been increasing , which is consistent with the loss of Basin population during the 2000’s. In 2017, Douglas County has showed an increase of absentee ownership from 54 percent to 56 percent but Washoe County had a much larger increase from 60 to 70 percent. El Dorado County has the highest share, at 78 percent, but this has remained steady since 2015. The City of South Lake Tahoe reports that about 12 percent of the housing stock is ofﬁcially listed as vacation rentals, but 56 percent of units are rental vs. ownership housing. Placer County data does not reﬂect a consistent geographic base through the years but the most recent data is concentrated in the Tahoe Basin area and shows a much higher absentee ownership rate. With so many absentee owners, this reduces social cohesion and has implications for the level of local support of community services, including hospitals. When more than half the homes are not primary residents, this results in fewer dollars spent at local businesses, less sales tax dollars and less community and civic engagement, when compared to full-time residents.
