Washington County permit authority
The first compliance decision is jurisdictional: identify the office with statutory authority over your parcel, then use its filing and inspection sequence to keep the project moving.
Jurisdictional status
Municipal Fallback
This profile identifies a handoff outside the county’s ordinary structural permitting lane.
Required jurisdiction check
Confirm the controlling local or state authority before filing.
The record is marked Municipal Fallback. That means the county profile should be treated as a routing brief: incorporated municipalities, a state building department, or a state fire marshal may control plan review, permits, and inspections. Contact the named agency below and verify the parcel’s jurisdiction before paying a fee or scheduling field work.

County Planning and Development contact is at the courthouse; county general hours were not published on the planning page. City of Washington City Hall: Monday-Friday, 7:30 a.m.-4:00 p.m. effective January 5, 2026; the city's public directory also lists 8:00 a.m.-5:00 p.m. for administration, so confirm before visiting.
Review expectation
N/A for ordinary county or municipal building permits because Washington County publishes no countywide timeline. County floodplain permits are normally issued within one week after a complete application is received; City of Washington permits expire one year after approval and become void if work does not start within 90 days or is suspended/abandoned for 90 days.

Project questions
Frequently asked questions for Washington County
Who handles permitting for this jurisdiction?
This record is marked Municipal Fallback. Confirm whether a city, state agency, or other local authority controls the parcel before filing.
How should I begin an application?
Begin with the online permit gateway listed in the application guide. If the portal does not recognize the address or project type, contact 319-653-7710 (County Planning and Development); 319-653-7782 (County Floodplain/Environmental); 319-653-6584 (City of Washington Development Services).
How long might review take?
N/A for ordinary county or municipal building permits because Washington County publishes no countywide timeline. County floodplain permits are normally issued within one week after a complete application is received; City of Washington permits expire one year after approval and become void if work does not start within 90 days or is suspended/abandoned for 90 days.
How are inspections scheduled?
For rural projects, contact the Iowa State Fire Marshal Division at 515-725-6145 or a state-licensed electrical contractor for required new-electrical inspections; contact County Environmental Health/Floodplain at 319-653-7782 for septic, well, or floodplain matters. For City of Washington projects, the permittee is responsible for calling for inspections before work is covered; contact Development Services at 319-653-6584. The county floodplain FAQ says completed floodplain applications are normally reviewed and issued within one week.
Which codes and exemptions should I review?
Washington County's official rural Building and Development guide states that the county has adopted no building codes and does not require a county building permit for unincorporated building projects. Iowa Statute 103 requires state inspection of all new electrical work in the county by licensed electrical contractors. Projects within two miles of an incorporated city may fall under that city's extraterritorial building or zoning requirements. In the principal municipal fallback, the City of Washington lists the 2018 International Building Code, 2018 International Fire Code, 2018 International Mechanical Code, 2018 Uniform Plumbing Code, and 2017 National Electrical Code; state and local requirements may differ elsewhere in the county. For ordinary rural construction, no county building permit is required because Washington County has no adopted building code and rescinded its zoning ordinance in 2013. This does not exempt development in the 100-year floodplain: virtually all man-made changes, including buildings, additions, sheds, grading, paving, excavation, drilling, and mobile homes, require a floodplain-development permit, including farm buildings and outbuildings. State electrical inspection, septic/well, driveway, 911-address, and city extraterritorial requirements may still apply. City exemptions vary by municipality.
