Since May 1, 2025, Rochester requires a building permit and three inspections for every residential siding replacement project. The city's Community Development Department handles permits at 507-328-2600.
As of May 1, 2025, the City of Rochester requires a building permit for all residential re-siding projects. This includes single-family homes, two-family homes, and townhouses. The rule brought residential properties in line with commercial and multi-family buildings, which already needed permits for siding work. Before this date, many homeowners replaced siding without permits, but that changed.
The permit process goes through the Community Development Department at 4001 West River Parkway NW, Suite 100. You can call them at 507-328-2600 during business hours Monday through Friday, 8:00 am to 4:30 pm, or email buildingsafety@rochestermn.gov with questions. They can tell you exactly what paperwork your project needs and what the current permit fee is.
For a re-siding project in Rochester, you do not need to submit plans. The permit application itself is enough. The fee is a fixed amount regardless of home size. Once the permit is issued, the city requires three inspections: wall sheathing, weather barrier, and final. Your contractor schedules these as the work progresses. The inspector makes sure the sheathing is solid, the weather barrier is installed correctly, and the finished siding meets code.
A building permit stays valid as long as work continues. If you stop work for 180 days without contacting the city by phone or email, the permit expires and you will need to renew it or start over. Most siding projects finish in one to three weeks depending on weather and home size, so expiration is rarely an issue. The city verifies that your contractor holds a valid state license when the permit is submitted.
Minnesota requires contractors doing siding work to hold a state license. If a contractor only does siding, they need a license for that trade. If they do both siding and windows, or siding and roofing, they need a Residential Contractor's License that covers multiple trades. The state considers siding and window installation separate skills. Homeowners doing their own work do not need a license, but they still need the permit and inspections.
Before you hire anyone, ask to see their state license and confirm it is current. The city checks this when the permit is filed, but you should verify it yourself before signing a contract. A licensed contractor knows the code requirements and can pull the permit for you, which saves you a trip to the city offices.
The permit and inspection requirement helps make sure siding jobs are done right. Rochester gets heavy snow, ice, wind, and summer storms. In 2024, the area saw severe thunderstorms in June and July with hail up to golf ball size and high winds. Siding installed without proper sheathing, weather barrier, and flashing can let water behind the walls, leading to mold and rot you will not see until it is expensive to fix.
Inspections catch problems early. If sheathing is damaged or missing, the inspector sees it before new siding covers it up. If the weather barrier is not lapped correctly or the flashing around windows is wrong, the inspector can point it out while it is still easy to fix. This protects your investment and keeps your house watertight through Minnesota winters and storms. If you are planning a siding project, contact the Community Development Department at 507-328-2600 to confirm current rules and fees before you start.
