Jasper County, Iowa
Construction & Remodeling
Jasper County covers 730 square miles east of the metro and holds 38,153 people. It organized in 1846, and Newton has been the seat since. Outside Iowa, Newton is best known for Iowa Speedway.
The housing is old. The median home here went up in 1965, 26.8 percent of the stock predates 1940, and only 4.8 percent dates from 2010 or later. This is a remodeling and additions county.

Full-Service Construction and Remodeling Across Jasper County
A new home on rural ground needs a county permit from Community Development at 641-792-3084, plus four inspections: footings, foundation walls, rough in and final. Inside Newton the city reviews the plans, and permits usually issue in 2 to 3 business days. Show your lot pins at the foundation inspection, because no permit issues while property lines are unclear. Newton publishes a 42 inch frost depth, and we set footings to that depth countywide. Home building starts at $150 per square foot, and final costs vary by scope, materials and complexity.
This is a remodeling county by the numbers. The median Jasper County home went up in 1965, 26.8 percent of the stock predates 1940, and only 4.8 percent dates from 2010 or later. Whole house or phased, the first question is which code edition applies, because the county, Newton and Colfax do not match. We confirm that with the permit desk, then open a small area early and price from what we find. Phased work spreads cost across seasons without leaving you without a kitchen for months.
A 1965 kitchen was built for one cook, one oven and a small refrigerator. Opening it up usually means moving a wall, a vent or a gas line, and a permit follows. Inside Newton that goes through the Building Division at 641-792-6622. Inside Colfax, the City Administrator handles both zoning and building at 515-674-4096. Outside both cities, the county reviews it. Older houses hide surprises behind the plaster. Kitchen remodeling starts at $250 per square foot, and final costs vary by scope, materials and complexity.
Older basements here fail today’s rules in quiet ways. Ceiling height under 7 feet. A bedroom window too small to count as egress. A stair with the wrong rise. We sort the must change items from the want to change items before design starts. On a hillside lot we check the uphill wall first, because the gumbo till pushes groundwater sideways. A seepage problem has to be solved before drywall goes up. Fixing it afterward costs several times more than fixing it now.
A bathroom packs more trades into less space than any other room. On county work the rough in is one of the four required inspections, so the plumbing and wiring get looked at before anything closes up. Inside Newton, Veenstra & Kimm, now part of Kleinfelder, handles inspections at 515-850-2980. We lay out clearances on the floor before ordering anything, because an inch matters at a door swing. A basement bath needs a drain plan before demolition, not after. Inside Colfax, one person signs off on both zoning and building.
An addition changes your foundation footprint, which is where local rules bite. Colfax requires trench footings at least 42 inches below finished grade with two #4 horizontal reinforcing bars. Newton publishes the same 42 inch frost depth, a 30 psf snow load and a base wind speed of 80 mph in Exposure B. On county ground an addition needs its own permit and four inspections. We build additional stories, sunrooms, garages, ADUs and tornado shelters. Additions start at $300 per square foot, and final costs vary by scope, materials and complexity.
Finishing a basement here starts with water. On a slope, the gumbo till sends groundwater sideways, so the uphill wall gets footing drains and free draining backfill before anything else happens. Then three numbers matter. A bedroom needs an egress opening with 5.7 square feet of net clear area. Habitable ceiling height runs 7 feet minimum. And we test for radon before we finish. Every Iowa county sits in EPA Zone 1, and Iowa averages 8.5 pCi/L indoors against 1.3 nationally.
A deck needs a permit in most of this county, and the rules differ across all three jurisdictions. Colfax narrows the standard permit exemptions, so work the model code lets you skip can still need a permit at 515-674-4096. Newton and the county each run their own review. Footings go below 42 inches, the depth Newton publishes and Colfax writes into its own code. We size footings for the span, flash the ledger properly, and build guard height and stair rise to code.
THIS COUNTY INSPECTS, ITS NEIGHBORS DO NOT
Iowa does not make a county adopt a building code. Boone, Warren, Story, Guthrie and Marshall counties never have, so outside their city limits nobody checks your structure.
Jasper County broke that pattern. It passed Ordinance 40D on March 26, 2024, adopting a full county building code. It also employs its own Building Official and two Inspection Technicians, who inspect in house rather than by contract.
The county requires four inspections on rural work: footings, foundation walls, rough in and final. That is real oversight on rural ground, and it is rare in Central Iowa. It also means your schedule has to leave room for four visits, so we book them into the calendar early.
- Ordinance 40D, passed March 26, 2024, adopts a full building code for unincorporated Jasper County
- Footings, foundation walls, rough in and final each get their own required county inspection
- A 28E agreement with Newton, Resolution 2019 from September 17, 2019, lets each cover the other
REAL INSPECTIONS AGAINST A 2006 CODE
Here is the part nobody volunteers. Ordinance 40D adopts the 2006 I-Codes. The inspections are real, but the code behind them is not current.
Now count the vintages inside one county line. Unincorporated Jasper County runs 2006. Newton runs the 2015 editions with the 2020 National Electrical Code. Colfax runs 2018.
Three jurisdictions, three vintages, and that is exactly what trips up a homeowner comparing quotes. Two bidders can price the same house to two different rule sets and both be right. The lots just sit on opposite sides of a line.
So ask every bidder which edition they priced. We confirm it with the desk issuing the permit before drawings go out.
- Unincorporated Jasper County reviews against the 2006 I-Codes, adopted by Ordinance 40D in 2024
- Newton enforces the 2015 editions along with the 2020 National Electrical Code
- Colfax adopts the 2018 IBC, IRC, IFC, IPMC, IEBC and UPC, a third vintage inside one county
FEES DOUBLE IF YOU START TOO EARLY
County permits come from Jasper County Community Development at 315 W 3rd Street North, Suite 150, in Newton. Call 641-792-3084. The office runs 7:00 am to 3:00 pm, earlier than the courthouse, so plan the trip.
The county values work from the ICC Building Valuation Data tables, then charges from that number. It publishes no fee schedule, so we will not print a dollar figure here. Ask the office for yours.
One rule deserves your full attention. Permit fees double if work begins before the permit issues. The Building Official can reduce that for a demonstrated emergency, so do not count on it. We pull the permit first, every time.

FARM BUILDINGS SIT OUTSIDE THIS CODE
Section 14 of Ordinance 40D carves out two limits worth knowing before you plan anything.
First, the county code skips buildings exempt under Iowa Code 331.304. That covers farm houses and farm buildings adapted mainly for agricultural use. The test is the real use, so be straight with the county. A shop that is really a garage is a different conversation.
Second, the county code stops at a city boundary. It reaches inside a city only at that city’s option, which is why Newton and Colfax run their own rules.
Anything the residential code does not cover needs documents signed and sealed by a registered design professional. Post frame buildings get one narrow exception.
- Ordinance 40D section 14 exempts farm houses and farm buildings adapted mainly for agricultural use
- The county code stops at a city line and applies inside a city only at that city's option
- One exception covers post frame buildings up to 1,000 square feet with eave height 12 feet or less
GUMBO TILL SENDS WATER SIDEWAYS HERE
Jasper County sits on the Southern Iowa Drift Plain, Iowa’s oldest landscape. Loess caps the uplands, pre-Illinoian till shows on the side slopes, and poorly drained alluvial bottomland fills the valleys.
The layer to know is the gumbo till, a thick clay rich band that water struggles to pass through. Rain soaks down, meets it, and travels sideways. That creates seepage zones on hillsides.
So a walkout here can run wet on the uphill wall while the yard looks dry. We plan for it with footing drains, free draining backfill and grading that carries water away. Where drainage is a question, we pull parcel data from the USDA Web Soil Survey first.
- The South Skunk River is the main watercourse, with USGS gages at Colfax and near Newton
- Newton's design criteria sheet flags soils that swell, and Colfax amends its code for soils high in clay
- Outside city limits, floodplain work falls under county Ordinance 15E and Article 13 of the zoning ordinance
NEWTON AND COLFAX WRITE THEIR OWN RULES
Inside a city, the city governs. Newton’s Community Development Building Division works from 303 W 4th Street North, Suite 501. Call 641-792-6622. Newton contracts inspections to Veenstra & Kimm, now part of Kleinfelder, at 515-850-2980, and permits usually issue in 2 to 3 business days.
Colfax puts one person in both chairs. Under Colfax Code 21.05, the City Administrator serves as Zoning Administrator and as building official. City Hall sits at 20 W Howard Street, 515-674-4096.
We publish all eight service pages for both cities. A rural address outside them permits through the county at 641-792-3084. Call if you are not sure which side of the line you are on.
- Newton publishes a 42 inch frost depth and a 30 psf ground and roof snow load
- Colfax requires a building permit for all construction within 1,000 feet of its municipal wells
- Newton's median owner occupied value is $153,700 against $186,300 countywide, and Colfax's median home dates to 1953

FAQs About Building in Jasper County
Does Jasper County inspect my new home?
Yes, and that makes it unusual. Boone, Warren, Story, Guthrie and Marshall counties run no structural inspection at all. This county staffs a Building Official plus two Inspection Technicians, and it requires four inspections: footings, foundation walls, rough in and final. The county and the City of Newton also signed a 28E mutual substitute inspection agreement on September 17, 2019. Each covers for the other when an inspector is out, expressly to hold down contract inspection costs. Inside Newton or Colfax, the city handles inspections instead of the county.
Which building code applies to my Jasper County project?
It depends where the lot sits. Unincorporated Jasper County runs the 2006 I-Codes under Ordinance 40D. Newton runs the 2015 editions with the 2020 National Electrical Code. Colfax runs the 2018 editions. That is three jurisdictions and three vintages inside one county line. The gap is what trips up a homeowner comparing quotes, because two bidders can price the same house to two different rule sets. Ask every bidder which edition they priced, then confirm it with the desk that issues your permit. That one call costs less than redrawing plans.
What does a Jasper County building permit cost?
The county values the work from ICC Building Valuation Data tables, then charges from that number. It publishes no fee schedule, so nobody should quote you a figure off a web page, us included. Call Community Development at 641-792-3084 with your square footage and scope, between 7:00 am and 3:00 pm. One rule is worth repeating. Permit fees double if work begins before the permit issues. The Building Official can reduce that for a demonstrated emergency, but do not build a plan around it. We pull permits before anyone touches the ground.
Do I need a county permit for a farm building?
Often not. Section 14 of Ordinance 40D says the county code does not apply to buildings exempt under Iowa Code 331.304. That covers farm houses and farm buildings adapted mainly for agricultural use. The test is the actual use, so be straight with the county about what the building is for. A shop that is really a garage is a different conversation. Anything outside the residential code needs sealed documents from a registered design professional. The exception is a post frame building up to 1,000 square feet with eave height 12 feet or less.
Why does my hillside basement seep when the yard looks dry?
Blame the gumbo till. Jasper County sits on the Southern Iowa Drift Plain, where loess caps the uplands over much older glacial till. Inside that till sits a thick clay rich layer water struggles to pass through. Rain soaks down, hits it, and travels sideways along the slope. That is why a walkout can run wet on the uphill wall while the lawn drains fine. We answer it with footing drains, free draining backfill, a working sump and grading that carries water away from the house.
Is Busy Builders licensed in Iowa?
Iowa registers general contractors rather than licensing them. We hold registration with the Iowa Department of Inspections, Appeals and Licensing. Iowa Code Chapter 91C requires it of anyone earning $2,000 or more a year from construction. Electricians, plumbers and HVAC technicians do hold separate state licenses, and we work with licensed trades on every job. This county actually inspects rural work, which few Iowa counties do. Ask any bidder which code edition they priced. Busy Builders has served more than 1,285 Central Iowa homeowners since 2020.
