The City of Davenport's Development and Neighborhood Services Department at 1200 East Forty-Sixth Street permits and inspects construction for the largest of the Quad Cities. The department combines what were previously separate planning and zoning and neighbourhood services functions, and sits out on the city's eastern side rather than downtown.
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?
Iowa splits its building code into a part that applies everywhere and a part that does not. The State of Iowa Building Code sits at 661 Iowa Administrative Code, adopted under Iowa Code chapter 103A by the Building Code Bureau within the State Fire Marshal Division of the Department of Public Safety. Under chapter 103A a local jurisdiction has discretion to adopt the state code, to adopt a different code, or to adopt no building code at all — but certain portions apply to construction statewide regardless, most notably the energy conservation requirements at 661 IAC chapter 303. The state fire code and the state plumbing and electrical codes likewise run statewide through their own chapters and their own authorities. 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.
Where Davenport has adopted a building code, that code draws the exemption line and the jurisdiction may amend it. Ordinary repairs generally need no permit; construction, alteration, repair, demolition and any change of occupancy generally do. The statewide provisions apply either way: an application for a building permit, other than one to renovate or remodel a residential building of one or two units, must include a statement that the construction will comply with all applicable energy conservation requirements.
Typically permit required
- 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.
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.
How Iowa contractor credentials work
Iowa registers contractors with the Division of Labor and licenses the trades separately at state level. Electricians are licensed through the state electrical examining board and plumbers, mechanical and HVAC contractors through the plumbing and mechanical systems board, each valid across the state. A contractor doing business in Iowa registers with the Division of Labor, and out-of-state contractors face additional bonding requirements. Davenport may require its own local licence or registration on top of the state credential, and that is the requirement to confirm before a permit is pulled.
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
The first step on an Iowa project is establishing whether the jurisdiction has adopted a building code and, if so, which. A city or county that has adopted the state code enforces it locally; one that has adopted a different code enforces that; one that has adopted nothing has no general building permit requirement at all, though the statewide energy, fire, plumbing and electrical provisions still apply and the State Fire Marshal retains its own jurisdiction. That question is answered by the jurisdiction rather than assumed from its size. 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.
Trade permits and who may pull them
Trade work is permitted separately, under state codes that apply across Iowa rather than under whatever the local jurisdiction has adopted for general building.
Permit required
- Riverfront and low-lying sites — flood elevation and floodproofing established before design
- Electrical — separate permit, under the state electrical code and state licensing
- Plumbing — separate permit, under the state plumbing code and state licensing
- Mechanical — separate permit, under the state mechanical code and state licensing
- Fire protection — under the state fire code and the State Fire Marshal's jurisdiction
Typically exempt
- Like-for-like replacement the applicable trade code places below the permit threshold
- Work a property owner performs on their own residence, where the jurisdiction allows it
How to apply for a Davenport building permit
The state code, another code, or none at all; chapter 103A leaves the choice local.
Energy conservation, the state fire code and the state plumbing and electrical codes run statewide.
Zoning and subdivision are local in every case and precede the building permit.
Division of Labor registration, state trade licences, and any local requirement on top.
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 in Davenport
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.

Frequently asked questions
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 code Davenport has adopted; 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.
