Read Article AUBURN — The City Council voted unanimously Monday in a first reading to allow detached, “in-law” structures to be built in most residential zones in Auburn. Under current rules, even if a homeowner has the required land area and meets the density requirements, a second unit must be attached or contained within a single structure. The change will allow a second dwelling to be detached from the primary home. The proposal came as city officials consider a number of zoning amendments intended to encourage housing growth in Auburn. Those in favor of the proposal have said it would add to the diversification of housing options in the city, possibly freeing up homes for first-time buyers in a market low on inventory.
