Des Moines's Building Safety: The Rules That Matter
Every city handles building safety a little differently. In Des Moines, Iowa, there are 11 distinct rules that residents and property owners should be aware of. Some are stricter than what neighboring cities enforce, and others are more relaxed. Here is what you need to know.
Carbon Monoxide Detectors
Des Moines requires carbon monoxide alarms in rental units and rooming houses with a fuel-burning appliance or attached garage, placed near sleeping areas.
Key details: Applies to: Rental structures & rooming houses. Trigger: Fuel-burning appliance or attached garage. Placement: Outside each sleeping area. In-bedroom rule: If appliance is in the bedroom. Enforcer: Neighborhood Inspections Division.
Failure to install required alarms is a Code violation enforced by Neighborhood Inspections; unresolved municipal infractions carry a civil penalty up to $750 per violation, $1,000 for repeat offenses, under the citywide penalty schedule at § 1-15.
Lead Paint
Des Moines enforces lead-safe practices in pre-1978 housing through Chapter 8 building rules, Chapter 60 nuisance enforcement, and federal EPA RRP rules, with Polk County Public Health managing childhood lead poisoning case investigations.
Key details: Federal rule: EPA RRP. State law: IA Code 135. Local code: DSM Ch. 8. Investigations: Polk Co Health.
Performing renovations in pre-1978 housing without RRP certification, ignoring abatement orders, or failing to disclose known lead hazards in rentals leads to fines and possible federal referral.
This is one of the stricter rules in Des Moines's municipal code. If you are unsure whether your situation complies, it is worth checking with the city before proceeding.
Electrical Permits
Des Moines requires a permit from the Permit and Development Center before any electrical work or equipment installation, under the city's adopted State Electrical Code.
Key details: Permit issuer: Permit and Development Center. Governing code: State Electrical Code, adopted locally. Permit scope: Separate permit per building. Exemption: Wiring 50 volts or less. Fee basis: Set by city council resolution.
Work performed without a permit, or connecting electric current without notifying the electrical inspector, violates § 26-401. Only licensed electrical contractors and their licensed master/journeyman/apprentice workers may perform the work under §§ 26-450 and 26-451; unlicensed work is a separate violation enforceable by the building official.
Door Locking Hardware
Rental units in Des Moines must have exit doors that open from inside without a key, tool, or special knowledge, under the city's Rental Property Maintenance Code.
Key details: Applies to: Rental dwelling units and rooming units. Rule: No keys/tools needed to exit. Escape openings: Same no-key standard for window bars/grilles. Enforced by: Rental housing inspection division.
Cited under the Rental Property Maintenance Code as a life-safety violation; the rental unit can be flagged as non-compliant and the owner ordered to correct the hardware before the rental license is renewed or the property is re-inspected.
Building Inspections
Des Moines requires permit holders to call for inspections as work progresses and to schedule them within ten days of notice or risk a permit freeze.
Key details: Governing section: Municipal Code § 26-150. Scheduling deadline: 10 days after notice. Enforcement: Building official, permit freeze. After-hours option: Overtime inspection fee. Applies to: Des Moines city limits only.
Missing the 10-day scheduling window triggers a hold on all further permits for that applicant or property under § 26-150(b). Concealing work before inspection (§ 26-153) or ignoring a defect notice (§ 26-151, § 26-152) can lead to permit revocation, a misdemeanor citation, or a municipal infraction civil penalty under § 1-15, plus utility disconnection until re-inspection.
Plumbing Permits
Des Moines requires a plumbing permit for any installation, alteration, repair, replacement, or remodel regulated by the State Plumbing Code, plus a fee set by city council resolution.
Key details: Permit required: Any installation, alteration, repair, remodel. Issued to: Licensed plumbing contractor only. Fee: Set by city council resolution. Enforced by: City building official. Exempt: Routine maintenance (leaks, faucets).
Working without a plumbing permit, or deviating from approved plans without the building official's permission, is a violation of the plumbing code and can trigger enforcement action under Chapter 26.
Elevator Maintenance
Elevators in Des Moines buildings are regulated under Iowa Code Chapter 89A by the state Elevator Safety Bureau within Iowa Workforce Development, requiring annual inspections, state permits, and licensed contractors for installation and repair.
Key details: Authority: Iowa Workforce Development. State law: IA Code 89A. Inspection: Annual. Contractor: State licensed.
Operating elevators without a current state permit, missing annual inspections, using unlicensed contractors, or running equipment with safety defects can lead to red-tag shutdowns and fines.
Green Building Code
Des Moines does not impose a mandatory green building code beyond Iowa's adopted IECC energy code, but the 2024 Climate Action Plan promotes voluntary high-performance standards, EV-ready wiring, and electrification incentives for new construction.
Key details: Energy code: Iowa IECC. Local mandate: Voluntary. Plan: DSM Climate Action 2024. Preemption: Codes capped at state.
Failing to meet the state-adopted IECC during plan review or inspection delays certificate of occupancy, while voluntary green commitments tied to incentives may be clawed back if not delivered.
If you are coming from a city with tighter rules, you will find Des Moines gives residents more flexibility on green building code.
Building Permits
Any interior renovation touching building, electrical, mechanical, or plumbing systems in Des Moines needs a permit from the building official first, under Municipal Code § 26-135: a separate permit is required for each trade discipline and address.
Key details: Permit required: before any § 26-135 covered work. Issued by: city building official. Late-permit penalty: fee doubled, § 26-139. Violation penalty: misdemeanor or municipal infraction. Applies in: Des Moines city limits only.
Starting work without a permit lets the building official double the required fee under § 26-139, and unpermitted work can bring a misdemeanor charge or municipal infraction under § 26-156, plus city injunctive relief to stop the work.
Fire Sprinkler Requirements
Des Moines requires automatic fire sprinklers in townhouses and in one- and two-family homes of 8,000 square feet or more, with exceptions for smaller homes and existing buildings without a system.
Key details: Townhouse rule: Required in all townhouses. Single-family threshold: 8,000+ sq ft triggers requirement. Small townhouse exemption: 8 units or fewer exempt. Existing buildings: No retrofit on additions/alterations. Code section: § 26-310.10, amends IRC R309.
Building permits for noncompliant new construction are denied, and occupancy or a certificate of occupancy can be withheld until the required sprinkler system passes fire department inspection.
Childcare Center Rules
Childcare centers in Des Moines must meet Iowa Department of Health and Human Services licensing standards plus IBC Group E or I-4 building, fire, and egress rules under Chapter 8, with state inspections layered on top of city building permits.
Key details: State licensing: Iowa HHS. State law: IA Code 237A. Building code: IBC Group E/I-4. Local code: DSM Ch. 8.
Operating a center without state license or city occupancy approval, blocked exits, missing alarms, or under-staffing children can result in immediate shutdown by the state and city stop-use orders.
This is one of the stricter rules in Des Moines's municipal code. If you are unsure whether your situation complies, it is worth checking with the city before proceeding.
