Frequently Asked Questions
Can I build a triplex in Minneapolis?
Yes. Minneapolis made national history in 2020 by becoming the first major US city to eliminate single-family-only zoning. Under the Minneapolis 2040 Comprehensive Plan, up to 3 units (triplexes) are allowed by-right on all residential lots citywide, including former single-family zones. No special permits or variances are needed — triplexes are permitted as-of-right if the design meets zoning code standards.
Can I build an ADU in Minneapolis?
Yes. ADUs are allowed in Minneapolis residential zones. Under Minneapolis 2040, up to 3 total units are permitted on all residential lots. An existing single-family home can add an ADU (making it a duplex) or two additional units (making it a triplex). No owner-occupancy requirement applies. Permits are processed by Minneapolis Regulatory Services.
Does Minneapolis require a permit for short-term rentals?
Yes. Minneapolis requires a Short-Term Rental License ($100/year) for all Airbnb-style rentals. Properties must meet housing and fire codes. Unlike some cities, Minneapolis does not require the property to be the host's primary residence — non-owner-occupied STRs are allowed with a license.
What is the front yard setback in an R1 zone in Minneapolis?
The standard front yard setback in an R1 zone in Minneapolis is 20 feet from the front property line. Side yard setbacks are 5 feet each side, and rear yard setbacks are 25 feet. Minneapolis 2040 allows up to 3 units on R1 lots, but all units must comply with these setback standards.
Are solar panels required on new homes in Minneapolis?
No. Minnesota does not have a statewide solar mandate for residential construction. Solar is voluntary in Minneapolis. However, Xcel Energy (the primary utility serving Minneapolis) offers net metering and solar incentive programs for homeowners who do install solar panels. HOAs are limited in their ability to prohibit solar installations under Minnesota law.
