California Assembly Bill 1448 ("AB 1448") has been passed by lawmakers and is now awaiting the signature of Governor Jerry Brown. The new law would override any restrictions by homeowner associations that make it impossible to put up a clothesline or a drying rack.
AB 1448 is intended to conserve California's power supplies and reduce the amount of carbon that is released into the atmosphere by clothes dryers by allowing household occupants to dry clothes in the sun. To ease HOA concerns about the unsightliness of clotheslines and drying racks, language has been included in the law that limits the permissible locations to unshared backyards and other private outdoor areas. The law also specifically states that a balcony, railing, awning, or other part of a structure or building shall not qualify as a drying rack."
According to The Utility Reform Network there are currently six other states that have laws which override or strike down bans on clotheslines-- Florida, Maine, Utah, Vermont, Colorado, and Hawaii.
