The Hidden Tax on Housing: How Soft Costs Are Crushing Affordability
How soft costs — municipal fees, special districts, permitting delays, and NIMBY politics — quietly became a tax on housing. By ML Solutions Research Group · Published November 8, 2025 Ask a builder what killed a deal and you’ll hear about lumber, labor, interest rates, and supply chains — the hard costs everyone tracks. Spend enough time inside the pro formas, as we do, and a quieter line keeps turning out to be the thing that broke the math: soft costs. Municipal fees, special-district taxes, permitting delays, and the slow grind of local politics now add up to a real tax on housing, and in many markets it’s no longer a rounding error. NAHB puts government regulation at 23.8% of the final price of a new single-family home — 10.5% from development and 13.3% from construction.1 In Washington State, a 2025 analysis pushed that to 29.5%, roughly $203,976 on a $690,701 house.2 The 10–15% “regulation slice” a lot of us still carry in our heads has quietly moved into the 20–30% range. This sits alongside our work on rising hard costs and the changing labor market. Together, the three map how builders are getting squeezed from every direction at once.
“Margins Under Pressure: The New Economics of Homebuilding in 2025”
Rising construction costs: are builders winning the fight in 2025? By Mark Levinson · Published November 5, 2025 Builders are fighting back to reduce hard costs — or at least that’s what we tell each other. We preach “back to basics,” rationalize floor plans, build faster, and discount harder, and when that still isn’t enough we invite our “vendor partners” to share the pain, which usually means sharing our margin. I’ve sat on both sides of that conversation. Here’s the uncomfortable part: most of what’s squeezing us right now can’t be fixed with a sharper purchase order. The squeeze is real and it’s national. Material, labor, and financing costs are colliding with buyers who hit their affordability ceiling some time ago, after years of underbuilding and stubbornly high mortgage rates. Margins are thinner, timelines are longer, and managing risk now matters as much as managing the build. The bigger operators with scale have absorbed some of it; regional and mid-size builders — the people I spend most of my time with — are the ones struggling to keep production up. The result is the same undersupply we’ve been talking about for a decade, and continued pressure on prices, rents, and
