The Twin Cities ADU Race: Minneapolis Leads, but Saint Paul is Closing the Gap
At Hopewell 360, we are obsessed with a simple question: How do we make high-performance, comfortable housing more attainable? While many look to massive suburban sprawl or high-rise developments, we’ve always believed that the most elegant solution is already hiding in plain sight—right in our own backyards.
Accessory Dwelling Units (ADUs)—whether they are detached backyard cottages, garage conversions, or basement suites—represent a decentralized revolution in urban infill. But how is the ADU revolution actually playing out in our home turf? To find out, our team went straight to the source. We pulled and analyzed the raw, official building permit datasets from both the City of Minneapolis and the City of Saint Paul from January 1, 2021, through today.
The data reveals a fascinating tale of two cities: one with a massive head start, and another making bold regulatory moves to catch up.
The Raw Data: ADU Building Permits (2021–Present)
To get a true picture of ADU construction, we filtered out trade-only permits (like standalone plumbing or electrical hookups) and focused strictly on structural building permits where an ADU was the primary project.
The results show a clear frontrunner, but with an exciting shift underway:
Three Key Takeaways from the Twin Cities ADU Race
1. The Power of a Head Start: Minneapolis Leads the Way
Minneapolis has issued 2.4 times more ADU permits than Saint Paul since 2021. This isn't a surprise. Minneapolis legalized ADUs citywide back in 2014 and took the critical step of eliminating its owner-occupancy requirement in early 2021. By removing the rule that required the property owner to live on-site, Minneapolis unlocked ADUs for duplex owners, landlords, and multi-generational families alike, averaging a steady 17 permits per year.
2. Saint Paul’s 2023 Spike: What Happens When You Slash Red Tape
For years, Saint Paul’s ADU numbers languished in the single digits. But in late 2023, the Saint Paul City Council passed Ordinance 23-43, a sweeping reform that slashed barriers by allowing up to two ADUs per lot, increasing the maximum size to 800 square feet (or 75% of the main home), and raising height limits. The impact was immediate: Saint Paul’s ADU permits skyrocketed from just 4 in 2022 to 13 in 2023—nearly matching Minneapolis. It is a textbook example of how progressive policy immediately translates into physical housing supply.
3. The "Limiting Nutrient" is Still Construction, Not Zoning
While these numbers represent progress, they also highlight a sobering reality. An average of 17 units a year in Minneapolis and 7 in Saint Paul is a drop in the bucket for our regional housing shortage. The barrier is no longer the zoning code; it’s the sheer complexity and cost of traditional on-site construction. Building a traditional, stick-built ADU in a tight urban backyard often means tearing up landscaping, dealing with months of noise and neighborhood disruption, and navigating a maze of local utility hookups—frequently pushing costs past $200,000.
The Hopewell 360 Perspective: Modular is the Missing Link
At Hopewell 360, we don't just analyze these trends; we build the solutions. The data proves that Twin Cities homeowners want to build ADUs, but the traditional construction model is holding them back.
This is exactly why we leverage precision off-site modular construction. By building 80% of our structures in a climate-controlled facility, we bypass the weather delays, material waste, and labor shortages that plague backyard builds. When "Crane Day" arrives, we can install a fully finished, high-performance, net-zero-ready ADU on your property in a matter of hours, not months.
We are turning what used to be a six-month construction nightmare into a seamless, high-tech upgrade. Whether you want to generate passive rental income, create a space for aging parents, or add a home office, the backyard revolution is here—and modular is how we scale it.
Curious about what’s possible in your backyard? Whether you’re in Minneapolis, Saint Paul, or the surrounding metro, Hopewell 360 handles everything from zoning feasibility to final crane installation. Contact our team today to request a backyard assessment.
