Crawford County, Iowa Building Permit Guide

Outside city limits in Crawford County, the Zoning Administrator in the Engineer’s Office at the courthouse, 1202 Broadway, Suite 1, Denison (712-269-7418), issues a construction compliance certificate, the county’s building permit, for houses, additions, sheds, grain bins, livestock buildings, towers and solar arrays. Fees are small and flat: $10, $25 or $50 by project cost under the 2003 schedule, with no permit for patios and decks. The county checks setbacks and land use only; driveways need the Engineer’s access permit, and electrical permits come from the state.

What requires a permit in unincorporated Crawford County?

Crawford County’s zoning ordinance, adopted with the subdivision regulations in 1976 and amended since, applies to rural residential, agricultural, commercial and industrial property outside the cities. Building or altering a structure takes an application for a construction compliance certificate, and occupying it an occupancy compliance certificate; the Zoning Administrator issues both. Crawford posts permit forms written specifically for farm structures, including grain bins and cattle and hog confinement buildings.

Setbacks are printed on the forms. In the A-1 Agricultural district a lot must have 5 acres, with 40-foot front, 15-foot side and 30-foot rear yards; R-1 lots need 20,000 square feet with 30, 10 and 35 feet; commercial and industrial districts use 30, 20 and 25 feet. The farm setback is printed four ways. Ordinance 1979-1 sets farm houses, barns, outbuildings, wells and windbreaks at least 40 feet from the road right of way line, or 100 feet from each road at an intersection; the shed form says ag buildings must be 40 feet from the right of way; the bin form only recommends 40 feet; and the fee sheet lists 75 feet from the center of the road (100 near an intersection). The Board of Adjustment can grant variances. The same amendment bars commercial feed lots within two miles of any city’s limits.

What the county decides and what the state holds

The county’s posted ordinances cover zoning, subdivisions, the floodplain, water wells, septic contractor licensing and rural addressing, and they include no building code; the compliance certificate confirms the structure and use meet the zoning ordinance. Structural, plumbing and mechanical work on rural buildings is therefore not inspected by the county, while state energy rules, state trade licensing and the state electrical program apply.

Crawford County building department: who handles permitting

Tim Beery is the Zoning Administrator and also an assistant to the County Engineer, so zoning permits and road permits come from the same office in the courthouse. County Engineer Ben Schaben runs the secondary road system of about 1,200 miles of road and 280 bridges, and issues access, utility, tile-crossing, manure-pumping and oversize permits.

Rural addresses are assigned under the county’s Uniform Rural Address System Ordinance of 2001; ask the zoning office where to request one for a new house. The county’s ordinance list includes a 1989 water-well ordinance and a 2001 ordinance requiring septic contractors to be licensed, but the county site does not name the office that issues septic and well permits, so ask the zoning office before planning a rural water or sewer system.

Cities in Crawford County

Each incorporated city handles building permits inside its own limits; the county zoning fees apply to rural property owners only.

Crawford County permit types

Each permit form is the same two-part application, filed with a check for the fee: the owner asks for a construction compliance certificate, an occupancy compliance certificate or both, gives the township, section and quarter, lot or tract area and estimated cost, and describes the work. The project-specific versions add their own questions, such as rooms, baths and heating for a home addition, or doors, floor and utilities for a machine shed.

Residential permits

A new rural home uses the RR Home form and comes with the zoning office’s New Home Questionnaire, which records the finished house’s size, heating and features. Where a house’s only public access is a Level B or Level C service road, written concurrence from the County Engineer’s office is required before the permit is issued. A driveway needs its own access permit, and the house needs a rural address and a state electrical permit.

Commercial permits

Commercial and industrial buildings are priced by floor area rather than cost. Livestock confinements, commercial solar, wind turbines, wireless towers and anemometer towers each have their own form, and the county posts a wind turbine decommissioning ordinance. Uses needing a special use permit or variance go to the Board of Adjustment, and rezonings use the petition to change a zoning district. Revitalization tax abatement applications for commercial and rural residential or farm dwelling projects are handed out with the permit.

For tenant improvements and new commercial builds, Alliance handles commercial building permits through issuance. More on this: commercial building permits explained.

What comes before the building permit

• Floodplain. Under Floodplain Management Ordinance 1.17B (November 30, 2021), a floodplain development permit from the Zoning Administrator must be in hand before any floodplain development, including fill and grading; new or substantially improved homes must have the lowest floor, basement included, at least 1 foot above the base flood elevation, on fill at that height extending 18 feet beyond the building.
• Road access. The Engineer will not approve an entrance where sight distance is under 400 feet on gravel or 500 feet on a hard-surfaced road.
• Data centers. The supervisors held a public hearing on October 27, 2026 on a zoning amendment to regulate small, medium and large data centers in eligible agricultural, industrial, business and rural residential districts, each needing approval by the Board of Supervisors and meeting standards for site development, utilities, safety and decommissioning, and approved its first reading the same day; the latest posted minutes show no final adoption.

Crawford County permit costs and fees

Zoning fees come from the county’s schedule effective October 1, 2003, which applies to rural property owners only, and is printed on the back of each permit form.

Worked examples: a $320,000 rural home pays $50, a $40,000 machine shed $25, and a 14,000-square-foot commercial building $50 plus 4 × $5, or $70. The schedule does not say which band a project of exactly $25,000 falls in, so ask the office for a project at that figure. Neither the fee sheet nor the forms print a separate charge for the occupancy compliance certificate or for a floodplain development permit.

Driveway entrances are paid for by the applicant: the Application for Access commits the applicant to reimburse the county for the actual cost of materials, labor and equipment when county crews install it, and a contractor, landowner or tenant may build it instead with the Engineer’s approval. New entrance culverts must be at least 24 inches in diameter or 30 feet long; an owner-supplied culvert must be new corrugated metal pipe meeting the county’s specifications.

Trade permits and who may pull them

The county pages describe no county electrical, plumbing or mechanical permit, so rural wiring takes a state electrical permit from DIAL and a state inspection. Electricians, plumbers and HVAC contractors hold state licenses, and contractors earning $2,000 or more a year from construction work register with the state.

• Driveway installers. Anyone other than the county who builds an entrance must give the County Engineer a certificate of liability and property insurance with at least $500,000 per occurrence and $1,000,000 aggregate general liability, $500,000 automobile liability, excess liability and workers’ compensation.
• Utilities. Underground utility lines on private land are placed where the County Engineer and Zoning Administrator decide, with the supervisors’ approval, and work in the right of way needs a utility permit.
• Septic contractors. A 2001 county ordinance sets requirements for a septic contractor license.

Because entrance construction is a low-priority item for county crews, behind drainage cleaning and culvert, washout and bridge repairs, an owner on a tight schedule may use a private installer instead; all work is still subject to approval by county personnel, and on a standard entrance the county takes over culvert maintenance afterward.

How to apply for a Crawford County permit

Review, corrections and what causes delay

Most zoning permits are simple, but three things add time: a house whose only access is a Level B or Level C road waits for the Engineer’s written concurrence; a lot in the floodplain needs a floodplain development permit and, where the ordinance calls for it, an engineer’s or surveyor’s certification; and an entrance waits its turn in the county crews’ schedule. Variances, special uses and rezonings need Board of Adjustment or supervisor action.

Inspections in Crawford County

The county does not inspect framing, plumbing or mechanical work. Its compliance certificate and the occupancy certificate cover zoning and setbacks, and the zoning office sends the New Home Questionnaire because it so often finds owners away during its field inspections of new homes. Wiring is inspected by the state electrical inspector under the state permit.

In the floodplain, the Administrator keeps a record of the lowest-floor elevation of each new or improved building, and a professional engineer registered in Iowa must certify any floodproofing used instead of elevation for a non-residential building. Driveway entrances are checked by county personnel, who confirm the culvert, sight distance and slopes: 8 to 1 from a paved road with no culvert, 6 to 1 where a culvert is used, and 4 to 1 on gravel, with the entrance built at least 6 inches lower than the road edge.

Iowa building code

Crawford County enforces its zoning, subdivision and floodplain ordinances in the unincorporated area, and none of the ordinances it posts is a building code. FEMA’s Community Status Book lists Crawford County as participating in the National Flood Insurance Program, with flood maps effective December 2, 2021.

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

Crawford County permit search and official resources

There is no online permit search; zoning permits and floodplain records are kept by the Zoning Administrator, and access permits by the County Engineer, so ask that office about an existing permit for a parcel. Supervisors’ minutes, including the October 2026 data center hearing, are posted on the county’s meetings page.

Crawford County permit FAQs

Do farm buildings need a county permit in Crawford County?
