Can you add an ADU on this property?
Type a house number, street, and city, or use your location. Green means that path looks promising on the recorded lot. Gold means it may be possible. Red means this screen treats it as highly unlikely. The city still decides. Showing pathways available today.
Try:
A planning screen from the recorded lot and that city’s researched minimum, when the city is on file. “Likely” above 15,000 sq ft is this site’s planning band, not a city ordinance. Not a permit.
Each color names both paths. Switch to Internal or External to paint the map by one path.

Across Utah, your home may have room for a new chapter. An accessory dwelling unit, or ADU, can help you make more of the property you already own. Think of a basement apartment, a garage conversion, or a small backyard home, with its own kitchen, bathroom, and living space. It could give family more independence, create long-term rental income, or give you a smaller place to call home. From Lehi and Orem to Salt Lake City, every property is different. Start with the lot, then explore designs, access, parking, utilities, and a realistic budget. City rules and permits can be complicated. Utah ADU Builder helps you explore possible paths and connect with independent partners who can guide your project. Request your free property review at utahadubuilder.com. We will contact you within 24 hours to arrange an appointment.

Before you get started
Do I need to know which ADU I want?
No. Share whether you’re planning for family, rental income or more flexible space. We can help you compare the starting points.
Is the review free?
Yes. The initial ADU review is free. Design, engineering, permit work and construction are separate services whose scope and pricing you agree with a partner.
Who will contact me?
Utah ADU Builder will contact you within 24 hours to arrange an appointment. With your consent, independent partners may also contact you about your inquiry.
What if the map is unsure?
An uncertain result is a reason to investigate. Bring your address and your idea; we can help identify what needs checking before you commit.
