BEND, OR -- The Land Conservation and Development Commission met recently and adopted new rules to allow duplexes on single family lots. Nick Lelack with Deschutes County Community Development was recently appointed to the commission. He says the rules apply to medium sized cities between 10-thousand and 25-thousand residents. Lelack says the commission is fulfilling the requirements of legislation passed last year in House bill 2001, which seeks to support more housing options for Oregonians. The bill also requires larger cities to allow for triplex, quadplex and other multi-family units to inhabit single family lots. Those rules will be addressed this fall.
