# What a General Contractor Actually Does on Your Central Iowa Project

Homeowners search for “custom home project oversight” and “how to manage my own build” before they ever call a contractor. This guide explains what a general contractor does day to day on a home build or a large remodel in Central Iowa, what you are paying for, and where homeowners who try to run their own project usually get into trouble.

**TLDR:** A **general contractor** turns your plans into a permitted, scheduled, inspected and finished project. The job is sequencing trades, holding the schedule, managing the money, passing inspections and taking responsibility when something goes wrong. In Iowa a general contractor is a **registered contractor**, not a licensed one. The trades that need licenses are electrical, plumbing and HVAC, and the GC coordinates them.

## The question people ask before they call

Our search data shows homeowners typing “custom home project oversight” and “project management for homeowners” more than 700 times in the past year and a half. The question under both is the same: what does the contractor do that I could not do myself?

The honest answer is that some people can run their own small project. A single-room remodel with one trade is manageable. A [new home build](https://busybuildersiowa.com/home-building/) or a [home addition](https://busybuildersiowa.com/home-additions/) with eight trades, three inspections and a lender draw schedule is a different job. That job is what you are hiring.

Busy Builders has completed more than 1,285 projects across Central Iowa since 2020. Every one of them ran through the same sequence described below.

## The six jobs inside the job

**Pro Tip 1:** Ask any contractor you interview to walk you through these six areas. If they cannot, they are a tradesperson, not a general contractor.

The table below breaks down what a general contractor owns on a typical project.

Area What the GC does What goes wrong without it

Plans and permits Reviews drawings, submits the permit, answers plan-review comments Permit rejected, work starts without one, stop-work order

Scheduling Orders trades in the right sequence with lead times Drywall before the electrical inspection, three-week gaps

Trade coordination Hires and directs licensed electrical, plumbing and HVAC subcontractors Trades blame each other, nobody owns the conflict

Money Prices the job, manages draws, pays suppliers and subs Liens, unpaid subs, budget blown by month two

Inspections Calls for and passes footing, framing, rough-in and final inspections under the [Iowa state building code](https://www.legis.iowa.gov/docs/ACO/chapter/481.301.pdf) Failed inspections, rework, delayed occupancy

Accountability Carries insurance, warranty and the phone number that answers Homeowner is the only one responsible

The last row is the one people underrate. When something is wrong at month four, one person is responsible for fixing it. That person is the general contractor.

**Pro Tip 2:** Registration is not the same as licensing. In Iowa, general contractors register with the Department of Inspections, Appeals, and Licensing through [Iowa DIAL](https://dial.iowa.gov/). Electricians, plumbers and HVAC technicians hold separate state licenses.

## A week in the life of a project

Here is what a general contractor’s week looks like during framing on a new home in the Des Moines metro.

**Pro Tip 3:** Ask who will be on site and how often. “The owner stops by weekly” and “a superintendent is there daily” are different levels of oversight.

Day What happens Who the GC is talking to

Monday Confirm lumber delivery, walk the framing with the crew lead Framer, lumber yard

Tuesday Schedule the framing inspection, order windows against the rough openings City inspector, window supplier

Wednesday Electrical and plumbing rough-in walkthrough, resolve a beam conflict Electrician, plumber, engineer

Thursday Lender draw request with photos and invoices Lender, homeowner

Friday Inspection, punch list, next-week schedule to every trade Inspector, all subs

None of this is hard on its own. All of it at once, every week, for five months, is the job.

**Pro Tip 4:** The single most common failure on owner-run projects is sequencing. Insulation ordered before the rough-in inspection passes is a wasted week.

## What you pay for it

General contractors charge in one of two ways. A fixed price includes everything in the scope for one number. Cost-plus bills the actual cost of labor and materials plus a stated fee, often 15 to 25 percent. Both are common in Central Iowa.

**Pro Tip 5:** Fixed price protects you from overruns on a defined scope. Cost-plus fits a project where the scope will move. Know which one you are signing.

Pricing model You pay Best for Watch for

Fixed price One agreed number for the defined scope Clear plans, few unknowns Change orders on anything outside the scope

Cost-plus Actual costs plus a fee Custom builds, evolving scopes Fee applied to change orders, weak cost controls

Time and materials Hourly plus materials Small repairs, exploratory work No cap, no schedule

Our published starting points are about $150 per square foot for home building and $300 per square foot for additions. Those are planning figures; actual costs vary by scope, materials, site conditions and current pricing.

**Pro Tip 6:** Ask how change orders are priced before you sign. A written process with a markup stated up front is the sign of a contractor who has done this before.

**Pro Tip 7:** Ask for a draw schedule tied to milestones, not dates. Money should follow work. The [Consumer Financial Protection Bureau’s home buying guide](https://www.consumerfinance.gov/owning-a-home/) is a good primer on how lenders think about it.

Illustrative scenario: A family in [Urbandale](https://busybuildersiowa.com/urbandale/) hires a general contractor for a 2,600-square-foot custom home. The GC manages 11 subcontractors, 6 inspections and 7 lender draws over 7 months. The family attends a weekly walk and signs three change orders.

Illustrative scenario: An Ames couple tries to run a two-story addition themselves to save the fee. The framer and the electrician disagree about a chase, nobody resolves it, and the framing inspection fails twice. They hire a GC in month three.

Illustrative scenario: A West Des Moines homeowner uses cost-plus for a whole-house remodel with unknown conditions behind 1960s plaster. Two surprises add $14,000; the stated fee makes the math transparent.

## Where homeowners should stay involved

Hiring a general contractor does not mean stepping away. The best projects have an owner who shows up.

**Pro Tip 8:** Attend the walkthroughs before drywall. It is the last time you will see the wiring and plumbing.

**Pro Tip 9:** Make finish decisions early. Late tile and fixture choices are the most common cause of schedule slips in Central Iowa remodels.

**Pro Tip 10:** Keep one channel for questions. Customers tell us in reviews that being able to text the crew and get an answer is what they remember.

**Pro Tip 11:** Read the inspection reports. They are public record and they tell you the real status.

**Pro Tip 12:** Keep the plan set, permit and inspection cards in one folder. You will need them at sale.

The table below sets out the split.

Decision or task Homeowner General contractor

Design and finish choices Yes, early Advises, prices

Permit and inspections Signs as owner Submits, schedules, passes

Hiring trades Approves budget Selects, directs, pays

Schedule Reviews weekly Owns

Problems on site Informed Solves

A clear split keeps both sides out of each other’s lane and keeps the project moving.

## Frequently Asked Questions

**Q1: Is a general contractor licensed in Iowa?** No. Iowa general contractors are registered with Iowa DIAL, and the registration number should be on the contract. Electricians, plumbers and HVAC technicians are licensed. Ask for the registration number and the subcontractors’ license numbers.

**Q2: Can I be my own general contractor on a new home in Iowa?** You can pull an owner-builder permit in many cities. You then own the schedule, the trade contracts, the inspections and the liability. Lenders often require a registered contractor for construction loans. Most owners who try it on a full build hire a GC partway through.

**Q3: What does a general contractor’s fee cover?** Project management, scheduling, trade coordination, permit handling, inspections, insurance, warranty and accountability. On cost-plus jobs the fee is stated, often 15 to 25 percent. On fixed-price jobs it is built into the number.

**Q4: How often should I hear from my contractor?** Weekly at minimum during active construction, with a written schedule update. Daily during inspections and major milestones. If you have to chase for updates, that is a warning sign.

**Q5: What should be in the contract?** Scope, price and pricing model, draw schedule, change-order process, start and substantial-completion dates, warranty terms and the registration number. Read it before you sign it.

**Q6: How do I get started?** Call: [844-435-9800](tel:844-435-9800) for a free consultation. We will walk your site or your plans and explain how the project would run.
