Madison’s New Zoning Laws Make It Easier to Build ADUs—Here’s What It Means for You

Exciting news for homeowners in Madison! The Madison Common Council has approved a series of zoning changes that make it easier than ever to build Accessory Dwelling Units (ADUs) and other forms of “missing middle” housing. These updates open up new possibilities for homeowners looking to add space for family members, generate rental income, or simply make better use of their property.
At Boundless Tiny Homes, we’re ready to help you take full advantage of these new rules. Here’s what the changes mean and how we can help you get started.
What’s Changing?
The new zoning regulations remove some of the biggest hurdles that previously made building an ADU difficult. Key changes include:
✅ Bigger ADUs Allowed – The maximum size for an ADU has increased from 800 square feet to 1,000 square feet, giving homeowners more flexibility in their designs.
✅ More Bedrooms Allowed – ADUs are no longer limited to two bedrooms, meaning you can create a larger, more functional living space.
✅ Backyard Space Requirements Removed – Previously, properties had to maintain a certain amount of private backyard space, which often made ADUs impossible to build. That restriction is now gone.
✅ More Design Flexibility for Duplexes & Triplexes – If you’re considering a multi-unit property, the new rules allow for more creative layouts and configurations.
These changes are part of a broader push by the city to create more affordable and accessible housing options—and ADUs are at the heart of that solution.
Why This Matters for Madison Homeowners
If you’ve ever thought about adding a guest house, in-law suite, rental unit, or backyard cottage, these new zoning changes make it easier than ever to move forward.
ADUs can be a game-changer for:
🏠 Aging Parents – Keep family members close while giving them their own space.
💰 Rental Income – Earn extra money with a long-term rental or Airbnb unit.
📈 Property Value – A well-built ADU can significantly increase your home’s resale value.
🛠️ More Flexibility – Whether it’s a home office, studio, or guest house, an ADU adapts to your needs.
With fewer restrictions and more opportunities, now is the perfect time to start planning your ADU project.
