*Last updated October 2026*

Planning to build a house inside [Des Moines](https://busybuildersiowa.com/des-moines/) city limits in 2027? This guide uses the latest published figures as of October 2026. It shows what home building costs per square foot, what new city homes are valued at on their permits, and where the money goes. It also covers the Des Moines rules that change a budget, including the city’s tax abatement for new homes.

**TLDR:** Plan on a house budget that starts around **$150 per square foot**. The regional median custom home ran $177 per square foot before the lot. A 2,000-square-foot home lands near $300,000 to $354,000 for the house alone. New Des Moines homes averaged about $363,500 in permit value in 2025. City design rules add cost, and **tax abatement** can lower property taxes for five to ten years.

You have a lot in mind, or you are about to start looking. Before you talk to a lender, you want a number you can trust. Most cost pages online quote national averages that ignore Iowa winters, Des Moines zoning and the city’s tax breaks.

We built this guide around sources you can check. They include Census Bureau construction data, the National Association of Home Builders, and the city’s own code and tax pages. Every figure is current as of October 2026. Nobody publishes 2027 prices yet, so treat these as your planning baseline.

## What Does Home Building Cost in Des Moines Per Square Foot?

Plan on about $150 per square foot as a starting point for the house. Many custom builds land closer to the regional median of $177. That median comes from Census Survey of Construction data for custom homes started in 2025 in the West North Central division, which includes Iowa. The figure excludes the lot.

NAHB’s economists published those numbers in September 2026 in an analysis of the [custom home price per square foot](https://eyeonhousing.org/2026/09/custom-home-premium-highest-since-2011/). The national custom median was $171, so Iowa’s region runs slightly above the country, not below it. For the statewide view, see [what a custom home costs in Iowa](https://busybuildersiowa.com/what-does-it-cost-to-build-a-custom-home-2026/).

Here are the anchors we use for 2027 planning, as of October 2026.

Measure Figure What it covers

Busy Builders home building starting point About $150 per sq ft Planning estimate for the house, before the lot

Median custom home, West North Central (2025 starts) $177 per sq ft Contract price, finished floor area, lot excluded

Median custom home, United States (2025 starts) $171 per sq ft Same measure, national

Median spec home, West North Central (2025 starts) $162 per sq ft Builder-for-sale homes, lot value removed

The takeaway: $150 per square foot is a starting point. Finishes, size and site work move a Des Moines plan up from there.

**Pro Tip 1:** Ask every builder what their per-square-foot number includes. Some count finished basement space and some do not, which can swing a quote by tens of thousands.

**Pro Tip 2:** Price the house and the lot separately. A cheap lot that needs grading, tree removal or a long sewer run can erase its savings.

## What Are New Homes in Des Moines Valued At on Their Permits?

New one-unit homes permitted in Des Moines in 2025 carried an average construction value of about $363,500. That comes from the [Census Bureau’s 2025 building permit data](https://www2.census.gov/econ/bps/Place/Midwest%20Region/mw2025a.txt) for one-unit buildings. The Census Bureau defines valuation as the estimated value of the structure shown on the permit, so land is not included.

This table compares Des Moines with nearby suburbs using the same 2025 Census data.

City One-unit permits, 2025 Average permit value per home

Des Moines 221 About $363,500

Ankeny 668 About $362,300

Waukee 480 About $393,600

Urbandale 431 About $408,400

Johnston 122 About $508,700

West Des Moines 252 About $538,500

The takeaway: a new Des Moines home is valued on par with Ankeny and well below Johnston and West Des Moines. Cities estimate permit values in different ways, so use this as a rough guide, not a price list.

Permit counts also show where building happens. Des Moines issued 221 one-unit permits in 2025, about a third of Ankeny’s 668. If your lot sits inside an established neighborhood, you are building infill, and that changes the site work.

**Pro Tip 3:** On an infill lot, ask the city early about sewer and water connections. An older street can mean a longer or deeper service line than a new subdivision.

**Pro Tip 4:** Walk the block before you design. Des Moines house types use front setback averaging, so your neighbors’ setbacks shape where your house sits.

## How Much Does a 2,000 to 3,000 Square Foot House Cost in Des Moines?

A 2,000-square-foot house runs about $300,000 at the $150 starting point and about $354,000 at the regional median, before the lot. A 2,400-square-foot home, close to the national average size, lands near $360,000 to $425,000. These are planning estimates; actual costs vary by scope, materials, complexity and location.

For size context, the median new single-family home was 2,185 square feet in the second quarter of 2026, according to Census data analyzed by NAHB. The average was 2,426 square feet.

This table runs the math for common sizes at both anchors.

Home size At $150 per sq ft At $177 per sq ft Lot and site costs

1,600 sq ft $240,000 $283,200 Added separately

2,000 sq ft $300,000 $354,000 Added separately

2,400 sq ft $360,000 $424,800 Added separately

3,000 sq ft $450,000 $531,000 Added separately

The takeaway: size is the biggest lever you control. At these rates, every 400 square feet moves the house budget by roughly $60,000 to $71,000.

**Pro Tip 5:** Hold a contingency of 10 to 15 percent of the house budget. Iowa lots have a way of surprising people once the excavator starts.

**Pro Tip 6:** Decide early whether the basement gets finished now or later. Leaving it unfinished keeps it out of the first budget without giving up the space.

## Where Does the Money Go When You Build a House?

Interior finishes and major systems take the largest shares of construction cost. In NAHB’s most recent [Cost of Construction Survey](https://eyeonhousing.org/2025/01/cost-of-constructing-a-home-in-2024/), interior finishes were 24.1 percent and major system rough-ins were 19.2 percent. Framing came next at 16.6 percent.

The survey reports national averages only. Here is how those shares would split a $354,000 Des Moines house, the 2,000-square-foot example at $177 per square foot.

Construction stage Share of construction cost On a $354,000 house

Interior finishes 24.1% About $85,300

Major system rough-ins 19.2% About $68,000

Framing 16.6% About $58,800

Exterior finishes 13.4% About $47,400

Foundation 10.5% About $37,200

Site work 7.6% About $26,900

Final steps 6.5% About $23,000

Other 2.1% About $7,400

The takeaway: finishes and systems are more than 43 percent of the build, so that is where choices move your number most.

The same survey found construction was 64.4 percent of the average new home’s sale price nationally. The finished lot was 13.7 percent, and builder profit was 11.0 percent. Those shares explain why a quote for the house alone looks smaller than a new home’s listing price.

**Pro Tip 7:** Pick cabinets, counters and flooring before you sign. Finishes are the biggest stage, and allowances that are too low become change orders later.

**Pro Tip 8:** Keep the footprint simple. Every corner and roof break adds framing and exterior labor, the third and fourth largest stages.

## Which Des Moines Rules Change a Home Building Budget?

Des Moines layers zoning design rules on top of the building code. The city adopted the 2024 International Residential Code effective January 1, 2026, according to its [construction codes page](https://www.dsm.city/departments/development_services/permit_development_center/construction_codes.php). That page also lists the 2015 International Energy Conservation Code and a 42-inch frost line depth.

New houses in Des Moines also go through a house type review under the city’s zoning code. The city posts a submittal checklist for each house type on its [residential permits page](https://www.dsm.city/departments/development_services/permit_development_center/residential/index.php).

This table lists requirements from those checklists that show up in a budget.

Des Moines requirement Where it comes from Budget effect

Garage of at least 288 sq ft for single-unit houses House type checklists A garage is part of the base budget

Four-inch trim on street-facing windows House type checklists Added trim material and labor

Air conditioner screened from the street House type checklists Screening or a side-yard condenser

Limits on vinyl cladding on the first-story street facade House type checklists Another cladding material on part of the front

One street tree per 30 feet of frontage (House Type A) House type checklists Trees in the landscape budget

Footings at least 42 inches deep City design criteria Standard Iowa frost protection

The takeaway: the street side of a Des Moines house carries specific requirements, so budget it line by line.

Statewide, HF 2297 was signed and took effect July 1, 2026. Its passive radon requirement for new homes takes effect once the State Building Code Commissioner adopts it into the code.

**Pro Tip 9:** Ask your designer which house type your lot falls under before drawing elevations. The checklist differs by type and zoning district.

**Pro Tip 10:** Read up on [Iowa’s radon law for 2027 builds](https://busybuildersiowa.com/iowa-radon-law-hf-2297-new-homes-2027/) before you design. Iowa HHS lists Polk County, Altoona, Bondurant and Norwalk among places that required radon-resistant construction before July 2026. Des Moines city was not on that list.

## How Does Des Moines Tax Abatement Work for a New Home?

New homes in Des Moines can qualify for a property tax abatement that lasts five to ten years, on a declining schedule. Tax abatement is a temporary reduction in property taxes on value added by new construction. To qualify, the project must raise assessed value at least 5 percent and carry its required permits.

The schedule depends on location and two building choices, according to the city’s [low-density residential tax abatement page](https://www.dsm.city/departments/development_services/permit_development_center/tax_abatement/low_density_residential_tax_abatement.php).

New home location With extra insulation and EV-ready garage Without them

Outside the targeted low-density area 6-year declining 5-year declining

Inside the targeted area, outside Riverpoint West 10-year declining 9-year declining

Riverpoint West area 6-year declining 6-year declining

The takeaway: outside Riverpoint West, adding the extra insulation and an EV-ready garage buys one more year of abatement.

The city defines the extras. Walls that separate heated space from unheated space, not counting foundation walls, need at least R-20 insulation. The garage needs a level 2 charger or the electrical box and raceway for a future one.

## What Des Moines Homeowners Ask Us First

The first question homeowners bring to our site is cost. Across our site, what it costs to build a house in Iowa drew more searches than any other non-brand question, in four different phrasings. That is why this guide leads with sourced numbers instead of a sales pitch.

Busy Builders is a registered Iowa contractor, DIAL registration C140184, based in West Des Moines. Check any builder’s registration with the state before you sign, and ask how they handle the Des Moines house type review.

On timing, Census data analyzed by NAHB shows homes built by hired contractors took about 11.7 months from permit to completion in 2025. In our region, the wait from permit to the start of construction averaged about one month.

**Pro Tip 11:** Start design in winter for a spring groundbreaking. The house type review and energy documents take time, and a complete plan set moves fastest.

**Pro Tip 12:** Ask your lender how a construction loan pays the builder before you set a budget. Our guide to [financing a custom home build in Iowa](https://busybuildersiowa.com/financing-your-custom-home-build-in-iowa-2026/) walks through draws and inspections.

**Illustrative scenario:** A couple buys an infill lot on the north side of Des Moines and plans a 1,800-square-foot ranch. At $150 to $177 per square foot, the house runs about $270,000 to $319,000 before the lot. They add the extra insulation and an EV-ready garage for the longer abatement, and the build takes about a year.

**Illustrative scenario:** A family compares a south-side Des Moines lot with a lot in Norwalk for a 2,400-square-foot two-story. The house budget is similar in both places, about $360,000 to $425,000. Norwalk already required radon-resistant construction, while Des Moines offers abatement, so they price both before choosing.

**Illustrative scenario:** An empty-nester couple tears down a small older house in Des Moines and builds 2,000 square feet. The house runs about $300,000 to $354,000, plus demolition and utility work. The street-facing trim and screened condenser add to the exterior line, and they move in about 13 months after design starts.

## Frequently Asked Questions

**Q1: How much does home building cost per square foot in Des Moines?** Plan on about $150 per square foot as a starting point for the house, before the lot. The median custom home in Iowa’s Census region was $177 per square foot for 2025 starts, as of October 2026. Size, finishes and site work decide where you land. Get a line-item estimate on your actual lot before you commit.

**Q2: How much does it cost to build a 2,000-square-foot house in Des Moines?** At $150 to $177 per square foot, a 2,000-square-foot house runs about $300,000 to $354,000 before the lot. Add the lot, utility connections and site work on top. A 10 to 15 percent contingency protects you from surprises below grade. Use those three pieces to set your loan request.

**Q3: Is building in Des Moines cheaper than building in the suburbs?** New Des Moines homes averaged about $363,500 in permit value in 2025, similar to Ankeny and below Johnston and West Des Moines. Those averages reflect what people built, not a price difference for the same house. Des Moines design rules can add exterior cost, while tax abatement can lower your property taxes. Compare the full five-year cost, not just the build price.

**Q4: Do new homes in Des Moines get tax abatement?** Yes, if the project raises assessed value at least 5 percent and has its required permits. Outside the targeted area, the schedule is five years declining, or six with extra insulation and an EV-ready garage. Inside the targeted area, it is nine or ten years declining. Confirm your lot’s area with the city before you design.

**Q5: How long does it take to build a house in Des Moines?** Homes built by hired contractors averaged about 11.7 months from permit to completion in 2025, according to Census data analyzed by NAHB. Design and the city’s house type review add time before the permit. A spring start usually means design work in winter. Ask your builder for a written schedule with permit and inspection milestones.

**Q6: What code does Des Moines use for new homes?** The city adopted the 2024 International Residential Code effective January 1, 2026. Its code page also lists the 2015 International Energy Conservation Code and a 42-inch frost line depth. New houses also go through a house type review under the zoning code. Ask your designer to check both before drawings are final.

## Key Takeaways

- **Starting point:** Plan on about $150 per square foot for the house, with the regional custom median at $177, both before the lot.
- **Local values:** New Des Moines homes averaged about $363,500 in permit value in 2025, near Ankeny and below the western suburbs.
- **Biggest costs:** Interior finishes and major systems are over 43 percent of construction cost, so choices there move your budget most.
- **City rules:** House type reviews add garage, trim, screening and street tree requirements that belong in the first budget.
- **Tax abatement:** New homes can earn five to ten years of declining abatement, and extra insulation plus an EV-ready garage adds a year.

Use those three pieces to set your loan request."}},{"@type":"Question","name":"Q3: Is building in Des Moines cheaper than building in the suburbs?","acceptedAnswer":{"@type":"Answer","text":"New Des Moines homes averaged about $363,500 in permit value in 2025, similar to Ankeny and below Johnston and West Des Moines. Those averages reflect what people built, not a price difference for the same house. Des Moines design rules can add exterior cost, while tax abatement can lower your property taxes. Compare the full five-year cost, not just the build price."}},{"@type":"Question","name":"Q4: Do new homes in Des Moines get tax abatement?","acceptedAnswer":{"@type":"Answer","text":"Yes, if the project raises assessed value at least 5 percent and has its required permits. Outside the targeted area, the schedule is five years declining, or six with extra insulation and an EV-ready garage. Inside the targeted area, it is nine or ten years declining. Confirm your lot's area with the city before you design."}},{"@type":"Question","name":"Q5: How long does it take to build a house in Des Moines?","acceptedAnswer":{"@type":"Answer","text":"Homes built by hired contractors averaged about 11.7 months from permit to completion in 2025, according to Census data analyzed by NAHB. Design and the city's house type review add time before the permit. A spring start usually means design work in winter. Ask your builder for a written schedule with permit and inspection milestones."}},{"@type":"Question","name":"Q6: What code does Des Moines use for new homes?","acceptedAnswer":{"@type":"Answer","text":"The city adopted the 2024 International Residential Code effective January 1, 2026. Its code page also lists the 2015 International Energy Conservation Code and a 42-inch frost line depth. New houses also go through a house type review under the zoning code. Ask your designer to check both before drawings are final."}}]}]
