Improving the Way Developers and Planners Assess Parking Demand

September 2025: Phase 5 Update

On September 25, the Salem City Council voted 10-1 to eliminate parking minimums for new multifamily housing developments in the City. This milestone follows over a year of MAPC technical assistance to the City on this effort and makes Salem the first municipality to directly apply the Perfect Fit Parking methodology to inform their zoning changes. The Phase 5 Salem study adds yet another contribution to a robust regional dataset that highlights how most communities have built more residential off-street parking than is needed or utilized.
