Roughly 30-40% of corridor home sales in any given year involve new construction — much higher in North Liberty and west Coralville, lower in central Iowa City where infill is the only option. Buying new is genuinely different from buying resale: different contract, different financing path, different inspection logic, different warranty.
Lot availability: where new is actually being built
The active corridor subdivisions in 2026 are concentrated in a handful of locations:
- Forevergreen (Coralville and North Liberty). The big one. Spans both cities. Production builders working in phases. Lot inventory rotates constantly as new phases open.
- Penn Ridge (North Liberty). Active North Liberty subdivision with family-oriented production product.
- Iowa River Landing (Coralville). Condo + townhome new construction. Walkable, mixed-use. Different product type — closer to urban infill.
- Western Iowa City infill. Scattered lots, tear-down opportunities, the occasional small subdivision. Custom or semi-custom only.
- Tiffin and Clear Creek Amana district. Cheaper land, longer commute, different school district. Worth a look if school flexibility works for you.
See our lot availability page for a deeper map.
The contract — and why it matters more than on resale
A resale contract is a standard one- or two-page Iowa purchase agreement with inspection and financing contingencies. A new-construction contract is typically 30-50 pages: base price, lot premium, upgrade allowances, change-order procedures, warranty schedule, completion deadlines, weather delay clauses, and the all-important "what happens if delivery slips by 90 days" provisions.
Bring a buyer's agent
The on-site sales rep at a model home represents the builder. Their commission is built into your price. A buyer's agent — at zero extra cost to you, in most cases — represents you, reads your contract, knows which upgrades are real value vs builder markup, and walks your punch list with you. See our realtor directory.
Standard vs upgrade: what's actually included
Corridor production builders package homes in tiers. "Standard" is the catalog finish; "upgrade" is everything else. The base price you see in marketing is almost always the lowest-tier standard package. Typical 2026 corridor standard inclusions:
| Item | Typical standard | Common upgrade |
|---|---|---|
| Flooring (main level) | Luxury vinyl plank | Hardwood, tile |
| Counters (kitchen) | Granite at base allowance | Quartz, level-2+ granite |
| Cabinets | Painted MDF, stock heights | Solid wood, full overlay, soft-close |
| Appliances | Builder-grade stainless package | GE Profile / Café / Bosch tier |
| Windows | Vinyl double-hung | Casement, triple-pane, wood/clad |
| Roofing | 30-year architectural asphalt | Class 4 impact-resistant, metal |
| Basement | Unfinished, rough plumbed | Finished package +$30-70K |
| Landscape | Sod front, seed back, 1-2 trees | Full landscape package, irrigation |
| Deck/patio | Not included | Composite deck $15-40K |
Permit and inspection timelines
Each corridor city handles permits differently:
- Coralville: 2-4 weeks for a standard single-family permit. Inspections are timely and reasonable.
- North Liberty: 2-4 weeks, sometimes faster. Building department has historically been builder-friendly.
- Iowa City: 4-8 weeks, longer if the home requires site-plan review or any zoning variance. More inspections, more documentation.
- Unincorporated Johnson County: Highly variable; depends on whether the site is in a sanitary district, on a septic system, or has special drainage requirements.
See our permits and zoning page for more on which projects require what.
Inspections during construction
Municipal inspectors will sign off at standard milestones: footing, foundation, framing, rough mechanical, insulation, drywall, final. They're checking code minimums — adequate, but not a quality benchmark.
Hire an independent inspector twice: once at the framing/rough stage (before drywall covers everything), and once for the final pre-closing walk-through. Cost is usually $400-$800 per visit. Catching one moisture-trapping flashing detail before drywall is worth ten times the inspection fee. See our home inspection page.
Closing on a new build
The new-construction closing timeline:
- Contract signing: 7-12 months before closing. Earnest money paid (typically $5K-$25K, sometimes 10% of base price for custom).
- Construction phase: Builder finances the build. You're not making interest payments on a construction loan unless you're doing true custom on your own lot.
- Mortgage application: 60-90 days before closing. Rate lock when you're confident on close date.
- Pre-close walk-through: 1-2 weeks before closing. You and your agent (and ideally an independent inspector) walk the home with the superintendent and generate a punch list.
- Certificate of Occupancy (CO): Issued by the city after final inspection passes. No CO, no close.
- Closing: Standard Iowa closing — title work, abstract update, deed, mortgage docs. Title premiums and recording fees as usual.
- Punch list completion: Builder finishes outstanding items in the weeks after move-in.
Warranty and the first year
Most corridor production builders offer a 1-2-10 warranty (1 year workmanship, 2 years systems, 10 years structural). Custom builders vary widely. See our full Iowa builder warranty page for the legal details and Iowa's 15-year statute of repose.
Year one is the time to find and report every issue: nail pops, drywall cracks at corners, sticking doors, grout issues, HVAC balance problems, grading and drainage issues that show up in a hard rain. File warranty requests in writing; keep copies of everything.

Frequently asked
Do I need a realtor to buy new construction?
No, but bring one. The builder's sales rep represents the builder. A buyer's agent costs you nothing out of pocket in most cases and reviews your contract, flags upgrade markups, and walks your punch list.
How long do new-build permits take?
Coralville and North Liberty typically issue in 2-4 weeks. Iowa City runs 4-8 weeks. Site-plan review or zoning variances add time across all three.
What's typically "standard" vs "upgrade"?
Standard in 2026 usually includes LVP flooring, base-tier granite, builder-grade stainless appliances, vinyl windows, 30-year architectural shingles, sod front yard. Premium flooring, quartz, custom cabinets, finished basement, deck, and landscape upgrades are extras.
How does closing differ from resale?
You sign 7-10 months before closing. Builder funds construction. Pre-close walk-through generates a punch list. Certificate of Occupancy must be issued before closing. Otherwise it's a standard Iowa abstract-and-title closing.
Should I get an independent inspection on a new build?
Yes. The municipal inspector verifies code minimums, not quality. An independent inspector at framing and pre-close will catch flashing, insulation, HVAC, and finish issues. Worth $400-$800 per visit.
