Polk County, IA Ordinances (2026)

Polk County's zoning code does not set countywide construction start/stop hours for ordinary building. Construction noise must not be excessive at the lot line, and specific uses carry their own hours. Cities within Polk County set their own construction-hour limits.

Unincorporated Polk County has no countywide decibel-based quiet-hours ordinance. Noise is handled as a nuisance and, for zoned uses, must not be excessive at the lot line. Inside Des Moines, Ankeny, or other cities, the city's noise ordinance and its nighttime quiet hours apply.

A persistently barking dog can be treated as a nuisance in unincorporated Polk County and reported to Polk County animal control, contracted through the Animal Rescue League of Iowa. Rabies and dangerous-dog matters follow Iowa Code Chapter 351.

Outdoor events in unincorporated Polk County must meet the Polk County Noise Ordinance and obtain a sound permit if required, per the zoning code. Everyday amplified music is governed by the lot-line noise standard and nuisance rules; cities set their own amplified-sound limits.

Polk County does not set numeric decibel limits for general noise in the unincorporated area. Its zoning code uses a qualitative lot-line standard instead: noise must not be excessive at the property boundary. Cities in the county may set numeric dBA limits.

Industrial and utility uses in unincorporated Polk County must keep noise from being excessive at the lot line, and heavy-industrial and extractive/disposal uses require conditional-use permits with noise-abatement plans. Home occupations must produce no noise detectable at the property line.

Polk County has no ordinance specifically restricting leaf blowers in the unincorporated area. Leaf-blower noise is governed only by the general rule that noise not be excessive at the lot line. Any leaf-blower time or gas-model restrictions come from individual cities.

Statewide Iowa law requires every motor vehicle to have a working muffler and bans muffler cutouts and bypass devices. This applies on all highways in Polk County. The Sheriff and city police enforce it; a scheduled fine applies.

Outdoor music events in unincorporated Polk County must meet the Polk County Noise Ordinance, obtain a sound permit if needed, keep noise limited to the site, and are reviewed by the Sheriff's Department. Home-based outdoor music is governed by the lot-line standard.

Aircraft-in-flight noise is regulated federally by the FAA, not by Polk County. The county's zoning code references a 75-decibel noise cone defined by the Iowa DOT around airports and may require additional berm buffering to reduce airport noise. Des Moines International Airport is the metro's hub.

Polk County does not impose a primary-residence requirement on short-term rentals. Whether a whole-home, non-owner-occupied rental is allowed depends on the host city's zoning; unincorporated STRs must fit an allowed residential/lodging use under the county Zoning Ordinance.

Polk County sets no rule requiring a host to be on-site during stays. A traditional county 'bed and breakfast' use implies an owner living there, but whole-home unhosted rentals are generally allowed where zoning and the host city permit them.

Polk County imposes no cap on the number of nights a home may be rented short-term. Any night limit would come from a host city's ordinance. Iowa's lodging tax applies from the first rented night regardless of total nights.

Polk County only zones unincorporated land (Iowa Code Ch. 335); it has no county-wide Airbnb license. Most STRs sit inside Des Moines, West Des Moines, Ankeny or Urbandale, where the city issues any rental permit. In unincorporated areas the county Zoning Ordinance controls the use.

Iowa imposes a 5% state hotel/motel tax on all lodging, plus a local tax of up to 7%. A county's local tax applies only in unincorporated areas; inside Des Moines and other Polk County cities the city's rate (commonly 7%) applies on top of the 5% state tax.

Polk County has no special STR parking ordinance. Off-street parking follows the Polk County Zoning Ordinance for unincorporated homes and each city's zoning/parking code inside its limits. Guests must not block streets, fire lanes, or right-of-way.

There is no county-wide STR registry. Wherever the property sits, the operator must register with the Iowa Department of Revenue for the hotel/motel (lodging) tax before renting to transient guests, and comply with the host city's rental-registration rules.

Polk County sets no county-wide guest cap for short-term rentals. Occupancy is governed by the host city's rental or building code and by fire/health limits tied to the dwelling. Unincorporated rentals are bounded by septic capacity and the Zoning Ordinance's residential-use standards.

STR guests must follow the same noise rules as any resident. In unincorporated Polk County the county nuisance/noise ordinance controls; inside a city the municipal noise ordinance and quiet hours apply. Hosts are responsible for guest behavior.

Polk County does not require short-term-rental hosts to carry a specific insurance policy. A host city may condition its rental permit on liability coverage, and platforms like Airbnb provide limited host protection, but a dedicated STR/landlord policy is strongly advised.

Backyard barbecuing is treated as a recreational/cooking fire under Iowa's open-burning rules, so grilling with propane or charcoal at a single-family home is allowed without a permit. Standard grill propane cylinders need no permit; the fire code restricts LP-gas grills on some multi-unit balconies.

A backyard smoker is a cooking fire, exempt from Iowa's open-burning prohibition under 567 IAC 23.2(3)(e), so no Polk County burn permit is needed to smoke meat at home. Smoke that becomes a persistent nuisance to neighbors can still be abated under the county air-pollution and nuisance rules.

Iowa legalized consumer fireworks in 2017. In unincorporated Polk County the state window applies: use is allowed June 1-July 8 and December 10-January 3, only 9 a.m.-10 p.m. (later on July 4 and New Year's), and only on your own property or with the owner's consent.

Polk County requires a permit for open burning. State rule bars open burning of combustibles except listed exemptions; the county issues permits for disaster rubbish, tree trimmings, landscape waste, bonfires, right-of-way and prairie burns. No burning when the AQI is 90 or above.

Polk County has no special propane-storage ordinance for homeowners. Storage and use of LP-gas is governed by the fire code and NFPA 58 (the state and county's adopted construction and fire codes), which set tank size, clearance, and installation standards enforced through building and fire inspection.

Iowa's open-burning rules exempt recreational fires for cooking, heating, recreation, and ceremonies, so a backyard fire pit is generally allowed. Polk County still bars burning when the Air Quality Index reaches 90 or above, and rubber tires may never be used to start a fire.

Iowa lets you open-burn landscape waste (brush, branches, leaves) that originated on your own premises, but Polk County requires a permit for it. Clearing and grubbing burns must sit at least one-fourth mile from any building the burner doesn't occupy.

Iowa allows backyard burning of residential waste at dwellings of four family units or less, unless a local rule is stricter. That exemption is unavailable inside Des Moines, West Des Moines, Clive, Urbandale, Windsor Heights, and Pleasant Hill, and Polk County still bars burning when AQI is 90 or above.

Polk County, Iowa is not in a designated wildfire hazard zone. Iowa has no wildland-urban-interface (WUI) map or defensible-space code like Western states. Fire risk here is managed through the open-burning permit system and AQI limits, not through wildfire-zone building rules.

Iowa Code 10A.518 (formerly 100.18) requires smoke detectors in all single-family rental units and multiple-unit residential buildings statewide, including Polk County. Homes built since 1991 must have them, and homestead-credit filers must certify installation. Landlords must fix a dead detector within 30 days.

In unincorporated Polk County, dogs may not run at large. The Sheriff's Animal Control enforces county Ordinance 18-068 and Iowa Code 351; loose dogs are impounded and taken to the Animal Rescue League of Iowa (ARL). Cities like Des Moines set their own leash laws.

Polk County has no breed-specific ban. County Ordinance 18-068 and Iowa Code 351 regulate dogs by behavior — an individual dog is declared 'dangerous' based on its conduct, not its breed. Iowa law lets counties add controls, but Polk County's rules are behavior-based, not pit-bull or breed bans.

Iowa bans private ownership of dangerous wild animals statewide, and this applies in Polk County. Under Iowa Code Chapter 717F you cannot own big cats, bears, wolves, primates, large constrictors, venomous snakes, crocodilians and similar species. Common pets — dogs, cats, and typical caged animals — are not covered.

In unincorporated Polk County, chickens and livestock are governed by the county Zoning Ordinance under Iowa Code Chapter 335. Bona fide agricultural use is exempt from zoning, so genuine farms need no permit; hobby fowl on small residential lots may be restricted by district. Cities set their own hen rules.

Polk County sets no specific beekeeping ordinance. In the unincorporated county, hives fall under the Zoning Ordinance — treated as an agricultural use, so genuine farm apiaries are exempt under Iowa Code 335.2. Cities like Des Moines set their own hive limits and setback rules for urban beekeeping.

In unincorporated Polk County, livestock is a zoning matter under Iowa Code Chapter 335. Genuine agricultural use is exempt from county zoning (Iowa Code 335.2), so working farms keep cattle, horses, hogs and sheep without a county permit. Hobby livestock on small residential lots is limited by the zoning district.

Polk County's Animal Control Ordinance (18-068) covers licensing, vaccination and dangerous animals but sets no fixed household pet cap for the unincorporated county. Excessive numbers are handled through nuisance and animal-neglect law. Cities such as Des Moines set their own pet-count limits.

Polk County has no ordinance specifically banning the feeding of wildlife such as deer or waterfowl. Problem feeding that draws nuisance animals is handled through the county nuisance provisions, and deer are managed by the Iowa Department of Natural Resources. Some Polk County cities do restrict deer or waterfowl feeding.

Polk County's Animal Control Ordinance (18-068) covers cats as well as dogs — including rabies vaccination and at-large control — and impounded cats go to the Animal Rescue League of Iowa. Iowa's rabies-tag statute targets dogs, but cats fall under the county ordinance and state bite-reporting law.

Animal hoarding is addressed through Iowa's animal-neglect law (Iowa Code 717B.3), which applies in Polk County. Keeping so many animals that they lack food, water, sanitation, or shelter is animal neglect. The Polk County Sheriff and the Animal Rescue League of Iowa investigate and can seize animals from hoarding situations.

Polk County zones unincorporated land but does not run a city-style curbside parking program; on-street rules on county roads follow Iowa Code Chapter 321. Any vehicle a police authority finds parked on the highway creating a traffic hazard is an abandoned vehicle. Cities set their own street-parking rules.

The Polk County Zoning Ordinance defines a commercial vehicle as any motor vehicle used for business or bearing a business sign; farm equipment is excluded. Off-street parking counts are set by land use. Cities have their own limits on parking commercial trucks in residential yards.

New access onto Polk County roads is regulated for safety, and residential development must take access to local streets where possible. Business parking areas and driveways must be paved to SUDAS standards. A driveway access permit is required through Public Works before construction.

Polk County's Zoning Ordinance lets a licensed RV or camper be used as temporary shelter for up to 21 days a year (max 14 consecutive nights). Storing an unlicensed or inoperable boat/RV outdoors is a health nuisance. Your city may add its own rules.

Polk County has no countywide overnight on-street parking ban for its rural roads. State law lets a police authority impound a vehicle left illegally or unattended on public property for more than 24 hours. Overnight bans in neighborhoods are set by each city.

Iowa Code 321.89 lets a police authority impound a vehicle abandoned on public property (24-hour trigger) or private property. Separately, Polk County's Nuisance Regulation bans storing any unlicensed, unsafe or inoperable vehicle outdoors as a health nuisance the County can abate.

Polk County's Zoning Ordinance treats a place storing more than two inoperable vehicles (or parts exceeding 240 cubic feet) as a junkyard, which is a restricted use. Storing inoperable large vehicles, machinery or vehicular parts outdoors is also a health nuisance. Cities set residential size limits.

Polk County's Zoning Ordinance sets no dedicated electric-vehicle charging-station standard; EV chargers are treated as a normal electrical/building installation requiring a permit. Installations still meet Article 13 off-street parking design. Statewide, Iowa follows the National Electrical Code for charger wiring.

Polk County's rural county roads are largely uncurbed, so there is no county curb-color parking code; roadway traffic-control markings follow the state and MUTCD standards. Off-street parking lots must stripe standard-size stalls and provide accessible spaces per Iowa Code 321L and the ADA. Curb-color enforcement is a city matter.

The Polk County Zoning Ordinance requires off-street loading berths for buildings of 6,000+ square feet that need deliveries. Berth counts scale with floor area, each berth is at least 250 square feet, and loading areas must be paved. No truck may block the public right-of-way while loading.

The Polk County Zoning Ordinance sets fence height rules but does not require a standalone fence permit for an ordinary fence within limits. A building permit IS required for any retaining wall over 4 feet. Confirm current requirements with Polk County Planning & Development before you build.

In unincorporated Polk County, a retaining wall over 4 feet tall needs a building permit and must be set back from any property line at least 1.5 times its height. Walls closer than that need engineered design, and guard rails are required on walls 30 inches or more above grade

In unincorporated Polk County, residential fences may be up to 4.5 feet in the front yard and 6 feet in side/rear yards, never over 6.5 feet overall. Non-residential fences max out at 12 feet. Cities like Des Moines or Ankeny set their own limits.

Polk County's zoning ordinance requires fence posts and rails to face the property interior (finished side out) and bars any fence from blocking sight distance. It does not assign shared-fence cost between neighbors; that is handled under Iowa's partition-fence law, Iowa Code Chapter 359A.

Beyond height limits, Polk County requires swimming pools to be enclosed by a non-climbable fence at least 4 feet high with a self-latching gate, and livestock-confining fences to sit 100 feet or more from a neighbor's dwelling. Fences must never obstruct sight distance.

Polk County's zoning ordinance does not broadly ban residential fence materials such as wood, vinyl, or chain-link, but it requires chain-link with barbed-wire topping for certain hazardous utility and tank enclosures, and prohibits chain-link fence with slats for screening outside storage.

Polk County allows common fence materials for residential fences and does not impose a general material list, so long as height, sight-distance, and orientation rules are met. Special material requirements apply only to storage screening and hazardous-equipment enclosures.

Polk County's single-family bulk standards set minimum yard setbacks by zoning district. In Low Density Residential (LDR) the minimums are 35 feet front, 10 feet side, and 35 feet rear; agricultural districts require 50 feet front and rear. City-owned land uses municipal setbacks.

Polk County caps single-family building height at 40 feet in agricultural districts and 35 feet in the residential and mixed-use districts. Accessory buildings cannot exceed the principal building's height or 24 feet, whichever is greater. Cities set their own height limits.

Polk County limits maximum building coverage by zoning district, from just 5% in agricultural districts up to 40% in the higher-density residential and mixed-use districts. Coverage counts all principal and accessory buildings. Cities apply their own coverage limits.

Place your MWA cart within 18 inches of the curb on a level surface, lid closed, with the short metal bar facing the street. Keep three feet between carts, yard-waste bags, and structures.

Recycle paper, plastics with twist-off lids, aluminum and tin cans, and glass bottles and jars. Rinse them, keep them loose, and never bag recyclables – plastic bags are not recyclable in your cart.

Most Polk County households use Metro Waste Authority (MWA) curbside service. Set your cart out by 6 a.m. on collection day (or after 5 p.m. the night before). Extra bags and large items need paid stickers.

Large items (sofas, chairs, mattresses) go out curbside with $5 Large Item Stickers on your regular collection day, no scheduling. Appliances need seven $5 stickers and a scheduled pickup by calling 515.244.0021.

Iowa Code 455B.307A bans discarding solid waste onto any land or water of the state or into receptacles you're not authorized to use. Violators face a civil penalty up to $1,000 per violation, plus county nuisance abatement.

Under Iowa's noxious weed law (Iowa Code 317.10), every landowner must destroy noxious weeds on their land. Polk County treats weeds over 12 inches as a viable complaint; contact the Polk County Weed Commission.

In unincorporated Polk County, junk, debris, inoperable/unlicensed vehicles, and dilapidated buildings are "health nuisances" the owner must abate. Cities (Des Moines, Ankeny, West Des Moines) enforce their own blight codes inside city limits.

Unmaintained vacant lots and abandoned or unsafe buildings in unincorporated Polk County are health nuisances. An "abandoned building" is one vacant and in code violation for six months or more.

In unincorporated Polk County, letting litter, garbage, or organic waste accumulate on your property is a health nuisance. Storage in authorized receptacles subject to regular pickup and legal disposal is allowed.

Polk County's unincorporated area has no county-wide garage-sale permit in its nuisance code. Rules on frequency, duration, and signs are set by your city (Des Moines, Ankeny, Urbandale, West Des Moines). Don't leave leftover items as junk.

The Zoning Ordinance has no garage-sale-sign-specific rule. Small temporary/portable signs are treated as portable signs (a temporary sign permit, 14-day validity, 32 sq ft max) and may not be placed in the public road right-of-way.

Temporary political signs are allowed in unincorporated Polk County without a sign permit, but may not be erected earlier than 70 days before the election and must comply with Iowa Code 68A.406.

In unincorporated Polk County, the Weed Commission takes complaints for grass over 12 inches or plants on the Iowa Noxious Weed List. Cities set their own limits — inside Des Moines, contact the city (NID@dmgov.org).

Polk County sets no tree-removal or heritage-tree ordinance for private property. Removing your own tree is generally unrestricted; tree removal inside a city is governed by that municipality's code.

Polk County's Weed Commission explicitly does not handle complaints about trees or bushes. Tree-trimming disputes between neighbors are civil matters, and tree rules inside cities are set by each municipality.

Iowa Code 317.10 requires every landowner to destroy all noxious weeds on their land as directed by the county board of supervisors. Polk County's Weed Commission enforces this and takes complaints on listed weeds.

Polk County sets no lawn-watering schedule. Central Iowa's water is managed by Central Iowa Water Works / Des Moines Water Works, which can impose voluntary odd/even schedules or, in a shortage, mandatory bans.

Polk County has no ordinance banning native or prairie landscaping, and the county promotes native roadside vegetation. The one legal limit: your planting cannot include listed noxious weeds under Iowa Code 317.

Polk County allows backyard composting but regulates it through the Health Nuisance Regulation: a compost pile that harbors vermin, produces offensive odors, or accumulates garbage can be ordered abated.

Iowa has no state ban on collecting rainwater, and Polk County sets no rain-barrel ordinance. Residents may capture roof runoff in barrels or cisterns; only plumbing tie-ins to potable systems need a permit.

Polk County has no ordinance for or against artificial turf on residential lots. Installation on unincorporated land is generally unrestricted; cities and HOAs may regulate synthetic lawns.

A building and electrical permit is required before building any swimming pool in unincorporated Polk County. Only an electrical permit is required for a hot tub. Public/semipublic pools also need a state construction permit from Iowa HHS under Iowa Admin. Code 641—15.5.

A Polk County pool must be enclosed by a four-foot-high barrier (wall, fence, or house wall). Fences used as a barrier must be at least 48 inches high, with gates self-closing and self-latching, and no opening allowing a 4-inch sphere to pass.

Where a house wall serves as the barrier and doors/windows below 48 inches open toward the pool, Polk County requires self-closing/self-latching devices, an ASTM F1346 cover, or a UL 2017 alarm. Windows within 5 feet of the water must be tempered. Public pools follow Iowa 641—15.4 safety rules.

In unincorporated Polk County a hot tub needs only an electrical permit. Hot tubs and immersion pools are treated as swimming pools and need the 4-foot barrier unless equipped with a latching cover. All hot tub receptacle outlets must be GFCI protected.

Above-ground pools in unincorporated Polk County need the same building and electrical permits and setbacks as inground pools. The pool wall itself can count as part of the required barrier, but any stairs or ladder must be lockable, removable, or gated to block access.

Polk County requires no permit to remove a tree and takes no tree/bush complaints. The one county tree power: a tree with Dutch elm disease is a listed health nuisance the county can order abated by civil action.

Polk County's Customary Home Occupation Class I definition allows "no display" in connection with the home occupation, and the Class II standards state "Outdoor displays are not permitted." A home business in unincorporated Polk County therefore cannot advertise with outdoor signage or displays.

Under Iowa Code 137F.20, cottage food is exempt from all state licensing, permitting, inspection, packaging and labeling laws if sold and delivered by the producer directly to the consumer. Products must still carry name/address, common name, ingredients, and a residential-property disclaimer label.

The Polk County Zoning Ordinance permits a "Customary Home Occupation, Class I" — a use conducted entirely within a dwelling, incidental and secondary to residence, using no more than 25 percent of floor space and no more than one non-resident assistant. Class II allows uses inside a qualifying accessory building.

Customary Home Occupation Class I is a permitted use in essentially every Polk County zoning district, and Class II is permitted in the qualifying rural/residential districts. Confirm your parcel and use with Polk County Planning & Development before starting a home business in the unincorporated county.

Iowa allows an unregistered "child care home" to care for five or fewer children (or six or fewer if one is school-aged). A "child development home" providing care to seven or more children must register with Iowa HHS under 441 IAC 110. Polk County zoning treats it as a Day

Article 12 requires non-residential exterior lighting to use cutoff fixtures. Lighting must be a no-cutoff, total-cutoff up to 90 degrees, or total-cutoff at less than 90 degrees type, and non-residential projects must submit a lighting plan.

Exterior lighting must restrict glare and keep light from encroaching onto adjacent properties and the road right-of-way. Flickering or flashing lights are banned, and lighting near residential property faces added buffer restrictions.

A shed under 720 sq ft must sit at least 5 feet from side and rear property lines; larger sheds need 10 feet. Sheds must be at least 10 feet from the house, cannot exceed 24 feet in height, and generally cannot go in the front yard.

A carport is regulated as an accessory building. It must be at least 10 feet from the house, 5 feet from side/rear lines (10 feet if over 720 sq ft), cannot exceed 24 feet in height, and generally cannot sit in front of the principal dwelling.

Portable tiny homes cannot be used as accessory dwelling units in unincorporated Polk County. A fixed, code-compliant tiny house on a foundation is treated as a single-family dwelling or ADU and must meet all zoning and building-code standards.

Unincorporated Polk County allows one ADU per property, up to 1,200 sq ft and no larger than the principal residence. The owner must live on-site, the ADU meets principal-dwelling setbacks, and none is allowed in a FEMA floodplain.

Polk County's Zoning Ordinance has no separate garage-conversion rule. Converting a garage to living space is treated as an addition or an accessory dwelling unit and must meet ADU standards, district setbacks and the Polk County Construction Code.

Polk County Conservation parks are open 6:30 a.m. to 10:30 p.m. in summer and sunrise to sunset in winter. All visitors must leave before closing time, front gates are locked, and quiet campground hours begin at 10:00 p.m.
