A growing number of American cities are offering pre-approved building designs to developers in an effort to lower construction costs and accelerate housing production, according to a September 4, 2026 article by D. Dowd Muska published by the Pacific Research Institute. The trend has taken hold from the Pacific Northwest to the Southeast, with jurisdictions providing ready-made, code-compliant blueprints that bypass lengthy review processes. Los Angeles joined the movement following devastating wildfires in January 2025, launching a program that offers a virtual catalog of designs for single-family homes.
A national survey conducted by the Detroit Justice Center found that nearly one in four cities now operate active pre-approval programs. Among those programs, 61% shave more than one month off permitting timelines. Some municipalities reported cost reductions of $10,000 per unit. Seattle's initiative has produced 190 accessory dwelling units since 2019, with approval times dropping by a factor of 2.6 compared to standard processes. Tulsa released its T-Town HOME Catalog in June 2024, featuring 18 designs ranging from accessory dwelling units to a tenplex. Portland focuses on single-family homes and detached accessory dwelling units, while Yavapai County, Arizona offers six single-family designs at no cost through its A Home of My Own Program, launched in 2020.
The reform addresses flaws built into conventional approval systems, the article explains. Building departments "operate within fixed budget cycles, lengthy hiring processes, and administrative constraints that limit their ability to respond to sudden increases in workload," according to the Competitive Enterprise Institute. The National Association of Home Builders identifies "development review timelines and uncertainty" as "two of the most headache-inducing elements of the housing development process." Ned Resnikoff of the Roosevelt Institute calls the approach "essentially a win-win-win: Homebuilders get to move more quickly and save a little bit of money, the city doesn't need to spend finite staff hours on design review, and the city as a whole gets more housing."
Pre-approved designs work by eliminating redundant evaluations, the report notes. Before construction begins in most communities, blueprints pass through "a series of discretionary boards and commissions such as the planning commission, city council, board of adjustment and preservation committee." Municipalities now purchase or license access to plans and post them online for builders and buyers to browse. The selection varies widely—some cities offer just a handful of options, while others provide dozens. Programs may apply citywide or only in specific neighborhoods. Dream-home planner Jennifer Krouse told Muska that pre-approved designs appeal to officials because they're "politically neutral and quicker to implement than some of the structural problems we face, like increasing the cohort of contractors who build or reforming zoning." Cincinnati is accepting submissions for freely available plans covering two-, three-, and four-family buildings, with a design competition awards ceremony scheduled for September 14. The article concludes that given the scale of the affordable-housing crisis, solutions of any size deserve a welcome.
