Digital permit application gateway
Start with the issuing authority’s own submission lane. A complete application package, accurate valuation, and accessible inspection path are the fastest route through statutory plan review.
Recommended first click
Use the official digital gateway to submit plans, monitor review comments, pay required charges, and request inspections when the permit is issued. If the link is unavailable, use the agency website or phone number on the administrative profile to confirm the current lane.
Typical review lane
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.
Treat this as a planning signal, not a guaranteed approval date. Completeness, corrections, resubmittals, and agency workload control the actual clock.
Verify the parcel is inside this agency’s service area and note whether a city, state, fire marshal, septic authority, or utility district also has approval authority.
Prepare legible plans, site information, project valuation, ownership authorization, contractor information, and any energy, floodplain, zoning, or utility documentation the issuing office requires.
Keep the permit number, approved plan set, correction comments, fee receipts, and inspection results together. Those records establish the compliance trail for the next trade.

Source trail
Use these direct agency or licensing links to confirm current instructions before you file, pay, or schedule work. External pages control if their information differs from this directory.
Project questions
This record is marked Municipal Fallback. Confirm whether a city, state agency, or other local authority controls the parcel before filing.
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).

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.
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.
What makes an application complete
Before you click submit, make sure the drawings agree with the site plan, project description, valuation, ownership authorization, and contractor information. If the work changes structure, occupancy, drainage, fire protection, energy performance, or utility demand, describe that scope plainly. Ambiguous narratives create correction cycles and delay the field schedule.
Save the confirmation number, payment receipt, uploaded plan set, and every correction comment. Those records are the backbone of a defensible compliance file when multiple trades or agencies share responsibility.
Submission quality check
Site: address, parcel, access, setbacks, and existing conditions are consistent.
Scope: structural, mechanical, plumbing, electrical, fire, and energy work is identified.
Closeout: inspection contacts and the final approval path are understood before work begins.
