However, we did not find that the supply of housing was significantly affected by the incidence of short-term rentals in the City or County of Santa Barbara. This is because (1) compared to the total size of the housing stock, there are very few STRs in Santa Barbara City and County, and (2) very few of these homes are used as STRs full-time. . . Overall, we found that an STR ban across Santa Barbara County would increase the housing supply for local residents by only 0.1%.
