In our new report, “Unlocking Small Multifamily Housing through Building Code Reform,” https://buff.ly/2EwDHgg produced with Sam Naylor of Nominal, we look at how changes in local building codes could lead to the construction of more affordable, family-friendly housing, including triple-deckers, fourplexes, six-packs, and other smaller configurations. One challenge, as the report explains, is that housing development is being blocked by existing laws, building codes, and regulations. Small multifamily housing (SMH) in particular has been largely regulated “out of existence.” For example, once a project shifts from having two units to three units, “the building is subject to far more restrictive and costly regulatory requirements.” This can include such upgrades as “full building automatic sprinkler systems, additional fire-alarm systems, elevated fire resistance ratings for walls and floors, requirements for elevators and accessibility, increased energy and engineering requirements, larger minimum spatial standards, professional design and engineering requirements, and more.” These requirements often stem from a desire to prevent disasters, but they also often fail to take safety advances into account. There are safe, practical solutions that would help produce more, so-called missing middle housing. Policymakers could, among other strategies, revise safety and energy requirements. Policy could also be changed to allow for the construction of accessory dwelling units and single-stair construction of smaller builders that fit more flexibly on to smaller lots.
