Permits & Inspections

What Are Permits & Inspections?
A building permit is the city’s authorization to construct, and inspections are the checkpoints where a city inspector verifies the work meets the Minnesota State Building Code. New homes require a primary building permit plus separate plumbing, mechanical, and electrical permits; major remodels require permits whenever structure, egress, plumbing, or electrical are touched.
How the Process Works
- Plan review. Your builder submits construction drawings, a site survey, and energy-code documentation. The city reviews for code compliance and zoning (setbacks, height, lot coverage), typically 2–6 weeks in metro cities.
- Permit issuance. Fees are usually valuation-based; metro cities also collect sewer and water access charges (SAC/WAC) on new homes. Budget roughly 1–2% of construction value all-in.
- Inspections at milestones. Footings (before pour), foundation, framing, rough-in plumbing/mechanical/electrical, insulation/air-sealing, and final. Work can’t legally proceed past a milestone until that inspection passes.
- Certificate of occupancy. Issued after finals pass — the legal green light to move in.
Your builder pulls the permits. In Minnesota, the licensed contractor doing the work should always be the permit holder. A contractor who asks you to pull an owner’s permit for their work is dodging accountability — and often licensing — and it shifts liability to you. Treat it as a walk-away signal.
Why It Matters for Your Minnesota Build
Permits protect you in ways that surface years later. Unpermitted work routinely derails home sales (buyers’ inspectors flag it, and cities can require opening up finished walls), voids insurance claims tied to defective work, and eliminates the independent quality check inspections provide. Minnesota’s cold-climate code items — footing depth below frost (42–60 inches), energy code compliance, ice-and-water shield at eaves — are exactly the things you want a second set of eyes on.
Timing matters here too: metro building departments are busiest spring through fall. An experienced Twin Cities builder submits plans early so a footing inspection isn’t waiting on a backlog while good pouring weather passes.
