In Minneapolis and across Minnesota, re-siding requires a building permit and is inspected — and the inspections specifically check the things that prevent moisture failure. The typical sequence is a water-resistive-barrier (WRB)/rough inspection before the new siding goes on, an intermediate inspection for any sheathing or structural work, and a final inspection of the finished siding, trim, and flashing. Kick-out flashing must be installed when re-siding. A serious multifamily bid anticipates this path; one that treats it as afterthought paperwork is a warning sign.
This page walks boards, managers, and owners through what’s required and why the inspection sequence is actually your protection.
Do you need a permit to re-side in Minneapolis?
Yes — re-siding requires a permit in Minneapolis, and the work is inspected; it isn’t optional maintenance. The Minnesota Department of Labor & Industry publishes an official “Re-siding and the 2020 Minnesota Residential Code” fact sheet, and the City of Minneapolis administers building permits through its Community Planning & Economic Development construction-permit process. For multifamily, the permit and inspections are the mechanism that forces the wall-system details to be done correctly.
Skipping the permit isn’t a shortcut — unpermitted exterior work can surface during a sale, refinance, or rental-license inspection and become a costly problem. For boards, confirming the permit is pulled is part of fiduciary diligence; for apartment owners, it ties into rental-license and housing-code compliance.
What does the inspection sequence check?
The inspection sequence checks the wall in the order it’s built, so problems are caught before they’re covered: a WRB/rough inspection verifies the water-resistive barrier’s continuity and flashing integration, an intermediate inspection covers any sheathing or structural repair, and a final inspection checks the finished siding, trim, and flashing. The MN DLI fact sheet confirms that WRB and flashing installation is an inspected item on a re-side (MN DLI fact sheet); the exact number of stages and their names can vary by jurisdiction, so confirm the schedule with the Minneapolis building department on your permit. The WRB/rough inspection is the critical one — it happens while the barrier and flashing are still visible, before the new siding hides them.
| Inspection | When | What it confirms |
|---|---|---|
| WRB / rough | After WRB & flashing, before siding | Continuous water-resistive barrier; flashing integration |
| Intermediate | When sheathing/structural work occurs | Sheathing/rot repair done correctly |
| Final | After siding, trim, flashing complete | Finished cladding, trim, and flashing |
This sequence is precisely why a bid must price the WRB and flashing as real line items — the inspector will check them. See the wall system explained.
What does Minnesota code require for the wall?
Minnesota code requires a continuous water-resistive barrier behind the cladding (one layer of No. 15 asphalt felt or an approved equivalent system) and corrosion-resistant flashing applied shingle-fashion to keep water out of the wall cavity (MN Rule 1309.0703 / R703, MN DLI fact sheet). The 2020 Minnesota Residential Code adopts the 2018 IRC. These aren’t optional best practices — they’re code, and they’re inspected.
Critically, kick-out flashings must be installed when re-siding existing buildings (MN DLI fact sheet). Kick-out flashing diverts water away from the wall where a roof edge meets a sidewall — a small detail responsible for a large share of hidden wall leaks. Requiring it explicitly in the bid (and confirming the contractor installs it) is one of the highest-value, lowest-cost protections on the whole project.
Does multifamily fall under residential or commercial code?
Which code governs depends on the building. The Minnesota Residential Code (based on the IRC) covers one- and two-family dwellings and townhouses; apartment and condominium buildings with three or more dwelling units are generally classified as Group R-2 and fall under the commercial Minnesota Building Code (based on the IBC) instead (2020 Minnesota State Building Codes, MN DLI). That distinction can change fire-rating, exterior-wall, and inspection requirements, so it’s worth pinning down before bids are finalized — townhomes typically follow the Residential Code, while a larger apartment building usually follows the commercial code.
This matters because the code path can affect material choices (fire rating on attached buildings) and the inspection process. Don’t assume — have the contractor confirm with the Minneapolis building department which code governs your specific building before bids are finalized, so the scope and material reflect the right requirements. This is one of the wall-system questions to put to every contractor — see questions to ask a multifamily siding contractor.
How should permits and inspections show up in the bid?
Permits and inspections should show up in the bid as a named responsibility: who pulls the permit, who coordinates the WRB/rough, intermediate, and final inspections, and confirmation that kick-out flashing and the WRB are included. A bid that’s silent on permits leaves the obligation to fall on the board by default, and a bid that “doesn’t pull permits” is bidding unpermitted work — a serious red flag. The contractor should own the permit and the inspection scheduling.
Make sure the bid states:
- The contractor pulls the permit and coordinates all inspections
- The WRB and flashing (including kick-out flashing) are included and priced
- A sheathing/rot-repair allowance covers what the intermediate inspection may reveal
- The code path (residential vs. commercial) has been confirmed with the jurisdiction
These line items are part of what a real siding bid must include. Treating the inspection sequence as protection — not paperwork — is what separates a durable re-side from a repeat of the last failure.

Frequently asked questions
Q: Do I need a permit just to replace siding in Minneapolis? Yes. Re-siding requires a building permit and inspections in Minneapolis and across Minnesota — it’s not exempt maintenance. The MN DLI publishes a re-siding fact sheet confirming this, and unpermitted work can cause problems at sale, refinance, or a rental-license inspection.
Q: What is kick-out flashing and is it required? Kick-out flashing diverts water away from the wall where a roof edge meets a sidewall. Minnesota requires it to be installed when re-siding existing buildings. It prevents a common type of hidden wall leak, so confirm it’s explicitly included in your bid.
Q: What gets inspected when you re-side? Typically three stages: a WRB/rough inspection of the water-resistive barrier and flashing before siding goes on, an intermediate inspection for any sheathing/structural work, and a final inspection of finished siding, trim, and flashing. The WRB/rough inspection is the most important because it checks what gets hidden.
Q: Does my multifamily building follow residential or commercial code? One- and two-family dwellings and townhouses follow the Minnesota Residential Code; apartment and condo buildings with three or more units are generally Group R-2 under the commercial Minnesota Building Code. Confirm with the Minneapolis building department before finalizing the scope, since it can affect fire rating and inspections.
Want to be sure your bids name who pulls the permit and coordinates inspections? That’s one of the things a siding bid scope review checks.
