Community resistance to housing development remains a major barrier (NIMBY Opposition). Local leaders noted that opposition—often framed as protecting neighborhood “green space” or preserving single-family character—can reflect deeper resistance to multifamily density and infill. Many residents still associate new housing with congestion or environmental harm rather than recognizing its potential to improve public health, cost efficiency, and climate outcomes. To counter these perceptions, planners and advocates emphasized the need for “say yes to housing” messaging grounded in community values, highlighting how well-planned homes can reduce commute emissions, improve air quality, and create safe, stable environments for families.
