Marin is seeking public comment as it crafts new rules intended to balance the need for affordable long-term housing and the desire of homeowners to rent their homes to vacationers. The Marin Community Development Agency will present an updated short-term housing ordinance to the Board of Supervisors by the end of the year. If approved, the rules would replace the moratorium on new short-term rentals imposed a year ago. The C.D.A. has received 1,800 responses to its survey, which closes on May 1 and is seeking volunteers for focus groups on the subject. The county last updated its short-term rental policy in 2018, when it required property owners to notify neighbors before they could obtain a business license. Since the moratorium was imposed last May, heated opinions have been aired at public meetings. Supporters of a ban argue that short-term rentals deplete the supply of long-term housing and drive up rents, making it nearly impossible for the local workforce to find affordable housing in West Marin. But many property owners rely on income from short-term rentals to generate retirement savings or pay off their mortgage; they have strenuously objected to new limits, saying they would upend their financial planning.
