Des Moines Building Permit — Contractor Requirements and Local Bonds

Des Moines Permit Basics for Contractors

Des Moines does not require a separate city-level general contractor license. Instead, the city relies on your active DIAL (Department of Inspections, Appeals, and Licensing) registration as the baseline credential for pulling building permits. You'll present your state registration number at the Permit and Development Center when applying.

What Des Moines does enforce is a local bonding requirement and specific permit fees that are separate from anything at the state level. Understanding these local obligations before showing up at the permit desk saves you from mid-project delays.

Right-of-Way Bonds and When You Need One

If your project involves any work in the public right-of-way — excavation, utility connections, sidewalk replacement, curb cuts, or anything that affects city-owned property — you may need a minimum $5,000 Right-of-Way (ROW) Excavation or Obstruction Bond when required by the City Engineer.

The bond protects the city against damage to public infrastructure during your construction work. This is separate from your $25,000 state surety bond (if applicable) and separate from any workers' comp or general liability coverage.

For projects that block public property (sidewalks, street lanes), you'll also need an obstruction permit and a public liability insurance certificate approved by the Finance Director. The city takes this seriously — working in the right-of-way without a permit can result in stop-work orders and contractor penalties.

Permit Fees and Cost Structure

Des Moines uses a fee structure tied to project value and type:

For private construction contracts involving paving or sewer work, expect a flat administrative fee of approximately $900 per contract. Inspection charges run 6% to 8% of the first $30,000 of construction cost; confirm any charges above that amount against the current fee schedule.

Building permit fees for residential and commercial projects are calculated based on the project's total valuation using the city's fee schedule, available at the Permit and Development Center or through the city's online portal.

All permit applications go through the Des Moines Civic Access Portal. You'll need to create an account, upload your DIAL registration certificate, and submit project plans for review before the permit is issued.

The Des Moines vs. Des Moines, Washington Trap

This catches out-of-state contractors and online permitting services more often than you'd think. Des Moines, Iowa (Polk County) and Des Moines, Washington (King County) are frequently confused in automated business setup platforms.

The requirements are completely different. Des Moines, Washington requires a mandatory city business license before any construction permit — Iowa's Des Moines does not. Washington's city uses the MyPermits Online Portal, while Iowa's uses the Civic Access Portal. Mixing them up means you file the wrong paperwork with the wrong jurisdiction and waste weeks sorting it out.

When searching online for permit applications, always verify you're on dsm.city (Iowa) and not desmoineswa.gov (Washington).

What Triggers a Building Permit in Des Moines

Des Moines requires contractor registration for private construction and right-of-way work exceeding $500 in value. That's a low threshold — most construction work beyond basic maintenance will trigger the requirement.

Projects requiring permits include:

• New construction and additions
• Structural alterations and renovations
• Roofing and siding replacement
• Electrical, plumbing, and mechanical work
• Demolition
• Right-of-way excavation, utility trenching, and sidewalk/curb work

Homeowner-performed repairs on their own primary residence may be exempt from some permit requirements, but contractor-performed work on any property almost universally requires a permit.

Inspection Process

Des Moines conducts inspections at multiple stages during construction. The specific inspection points depend on the project type, but typically include foundation, framing, rough-in (electrical, plumbing, mechanical), insulation, and final inspections.

You're responsible for scheduling inspections through the Civic Access Portal. Work must stop at each inspection stage until the inspector signs off. Proceeding past an inspection point without approval can result in the city requiring you to tear back to the uninspected stage — an expensive lesson in compliance.
