The City of Davenport’s Development and Neighborhood Services Department permits and inspects construction for the largest of the Quad Cities through its Building Division at the Davenport Public Works Center, 1200 E 46th Street (563-326-7745), north of downtown rather than at City Hall. Plans are submitted through the city’s E-Plan electronic review system.
Davenport's defining physical fact is that it has no floodwall. Where most large Mississippi river cities built permanent flood defences, Davenport chose to keep the riverfront open, managing high water with temporary measures instead. The consequence for building is direct: on riverfront and low-lying land the flood elevation, floodproofing requirements and the mapped floodway govern what can be built and how, and those questions are settled from the floodplain data before design rather than at review.
This guide covers the City of Davenport in Scott County, Iowa. Bettendorf, Eldridge and LeClaire are separate Iowa cities; Rock Island, Moline and East Moline sit across the river in a different state entirely with separate requirements.
No floodwall means the floodplain rules do the work. Davenport has deliberately not built a permanent floodwall, keeping its riverfront open. That places the whole weight of flood management on elevation requirements, floodproofing and the mapped floodway for anything built near the water — settled from the floodplain data at the outset, because they determine the building's section rather than its detailing.
What requires a building permit in Davenport?
In Davenport the questions are what has been adopted locally, what applies whether or not it has been, and the city's adopted code and its floodplain requirements.

- Construction, alteration, repair, demolition or change of occupancy of a building or structure
- Floodplain review, elevation and floodproofing on riverfront and low-lying land
- A statement of compliance with applicable energy conservation requirements, on every application except a one- or two-unit residential remodel
- New buildings, additions and structural work on an existing building
- Alterations, repairs and renovations, and any change of occupancy
- Decks, accessory structures above the local threshold, retaining walls and swimming pools
Often exempt
- Ordinary repairs and small accessory work below the city's adopted threshold, and one- and two-unit residential renovation from the energy statement requirement
- Ordinary repairs that do not alter structure, egress or systems
- Painting, papering, flooring, cabinets and similar finish work
- Small accessory structures below the locally adopted threshold — zoning still applies
- Renovation and remodelling of one- and two-unit residential buildings, from the energy statement requirement
What is local, and what applies regardless
The general building code is Davenport's choice. It may adopt the state code by ordinance, adopt something else, or adopt nothing; where it adopts the state code it may also adopt its own administrative and enforcement provisions, establish a building department and designate a building official. What is not its choice is the statewide core: the energy conservation requirements, which apply to all commercial construction and to new one- and two-family residences whether or not a local code exists; the state fire code, enforced by the State Fire Marshal with local fire departments acting under agreement; and the state plumbing and electrical codes. Beyond those, the open riverfront and the floodplain requirements that stand in place of a floodwall.
Iowa lets most cities and counties adopt the state building code, another code or none (a city of more than 15,000 must enforce at least the state code), but the energy, accessibility, fire, plumbing, mechanical and electrical rules apply statewide. Iowa rules
Who handles permitting in Davenport?
Development and Neighborhood Services is the building authority for the city, enforcing the code Davenport has adopted alongside zoning, floodplain administration and neighbourhood services. The Building Code Bureau maintains the state code, the trades are licensed at state level, and the State Fire Marshal retains its own jurisdiction.

Permit types
Residential permits
A Davenport house project files with Development and Neighborhood Services against the code the city has adopted, with the energy compliance statement on every application except a one- or two-unit remodel. On the low ground near the river the flood elevation governs the finished floor and what may occupy the space below it.
Commercial permits
Commercial work in Davenport — the downtown and riverfront, the industrial corridors and the eastern commercial development — runs through the same department, with floodplain and floodway requirements on riverside sites and the statewide energy conservation requirements applying to all commercial construction, new or on an existing building.
Establishing what applies to the site
In Davenport the Mississippi floodplain and mapped floodway govern the riverfront in the absence of a floodwall, the downtown's historic building stock brings existing-building analysis into most renovation, and the bluffs behind the river carry their own drainage conditions.

Davenport permit costs and fees
Fees follow the city's schedule, with trade licensing handled at state level and floodplain review charged where the site requires it.
| Item | Fee or rule |
|---|---|
| Building permit | The city's fee schedule, by project type and construction value |
| Floodplain review | Elevation and floodproofing on riverfront and low-lying land |
| Trade permits | Electrical, plumbing and mechanical, each separately |
| Energy statement | Required with the application; no separate fee |
| Zoning | City approval ahead of the building permit |
| County permits | Scott County, for unincorporated territory only |
The state line is in the middle of the river. Davenport and Bettendorf are Iowa cities; the cities across the Mississippi are in a different state with an entirely separate code framework, licensing regime and permitting process. On a Quad Cities project the state comes before the city — nothing about an Iowa permit transfers across the bridge.

How to apply for a Davenport building permit
The state code, another code, or none at all — though a city of more than 15,000 people must enforce at least the state code.
Energy conservation, accessibility, the state fire code and the state plumbing, mechanical and electrical codes run statewide.
Zoning and subdivision are local in every case and precede the building permit.
DIAL contractor registration, state trade licences, and any local registration for general contractors.
Required on every building permit application except one- and two-unit residential remodelling.
Footing to final, with the trades on their own permits, then the certificate of occupancy.
Review, corrections and what actually causes delay
Davenport reviews against its adopted code, with floodplain requirements on the riverside. What delays a file here is an elevation assumed rather than taken from the data, a missing energy statement, and a project researched against the wrong side of the river.

Inspections follow the sequence of the code the jurisdiction has adopted — footing, foundation, framing, rough trades, insulation and final — requested from the local building department by permit number, with the trades inspected on their own permits. Work that passes final receives a certificate of occupancy for new buildings and changes of occupancy. Davenport inspects in the sequence its adopted code sets, with the trades inspected on their own permits and the certificate of occupancy following the finals.

Does Davenport have a floodwall?
No. The city has deliberately kept its riverfront open, so flood elevation, floodproofing and the mapped floodway carry the whole weight of flood management on riverside land.
Do the Quad Cities share a permitting process?
No. Davenport and Bettendorf are Iowa jurisdictions; the cities across the Mississippi are in a different state with an entirely separate framework.
What is the energy compliance statement?
A statement that the construction will comply with all applicable energy conservation requirements, required on every Iowa permit application except a one- or two-unit residential remodel.
Which code does the city enforce?
The 2021 International Building, Residential, Existing Building and Fire Codes, the 2024 International Mechanical Code, the 2024 Iowa Uniform Plumbing Code and the 2023 National Electrical Code, each with local amendments in Davenport City Code title 15. Under Iowa Code chapter 103A each jurisdiction chooses its own.
Does the county permit inside the city?
No. Scott County permits its unincorporated territory; the city permits inside its limits.
Who licenses electricians and plumbers?
State boards license the trades across Iowa.
