# Home Additions
 Waukee, IA

Adding on in Waukee starts with the lot. R-1 lots keep 30-foot front and rear yards, and the side yards must total 15 feet. A front addition also has to respect the setbacks of the homes next door. This page covers setbacks, footings, sprinklers, energy inspections and Iowa’s ADU law.

- Permits and rules

## Adding on to a Waukee home: the rules

Every addition in Waukee needs a permit before work starts. The lot decides how big it can be: R-1 setbacks, the front-yard averaging rule and height limits. Then come footings, energy inspections and porch valuations. Here is what applies.

### R-1 setbacks

On an R-1 lot, Waukee requires 30-foot front and rear yards for the house. The two side yards must total 15 feet, and one side may drop to 7 feet. Principal buildings may reach 3 stories or 40 feet. Check your plat, since many Waukee lots sit in other districts such as AR, R-2 or PD.

### Building toward the street

Waukee’s zoning code limits additions on the front of a house. Look at the first building on each side within 200 feet. A front addition cannot sit closer to the street right-of-way than the average of their front yards. Your neighbors’ setbacks help decide yours.

### Footings and drains

Addition footings in Waukee go at least 42 inches deep, the frost line and minimum footing depth in the city’s amended code. A foundation deeper than 42 inches in a newer plat needs sump pumps and footing drains. Our crews frame stud walls on the new poured concrete foundation.

### Sprinklers and energy

An addition does not force sprinklers on an existing Waukee home. The amended code exempts additions or alterations to buildings that do not already have them. Energy rules come from the 2012 International Energy Conservation Code, and the city requires energy inspections by a certified third party.

### Accessory dwelling units

State law now shapes ADUs. Under SF 592, an accessory dwelling can be up to 1,000 square feet. If 50 percent of the house is larger, that is the cap. No Iowa city may make owner occupancy a condition. Waukee’s zoning still decides where on the lot it fits.

### Porches and three-season rooms

Waukee values porch additions by type for the permit fee. A three-season porch counts at 50% of the ICC wood-frame value per square foot, and a screened porch at 15%. Other additions are valued at the contractor’s total cost, which cannot be less than the ICC-derived figure.

- Our process

## How Busy Builders builds your Waukee home addition

A Waukee addition starts with your plat and zoning district, the side-yard total and the front-yard average if you are building toward the street. We draw the addition, file the permit and hold work until it is issued. Footings go at least 42 inches deep, and a certified third party completes the energy inspections.

We build storm shelters, safe rooms and attached garages as part of addition work on request. Most of the 100-plus projects we complete each year are additions, full remodels and basement finishes.

- Plat, district and setbacks confirmed
- Permit issued before excavation
- Third-party energy inspection scheduled

- Frequently Asked Questions

## FAQs About Home Additions in Waukee

How much does an addition cost in Waukee?

Additions start from about $300 per square foot. Final costs vary by scope, materials, complexity and location within our service area. A second story, a basement under the addition or a bathroom inside it pushes the number higher. Waukee’s permit fee is based on the project’s valuation.

What are the setbacks for an addition in Waukee?

On an R-1 lot, 30 feet from the front line and 30 feet from the rear. The two side yards must add up to 15 feet, and one side can be as narrow as 7 feet. Other districts have their own numbers, so we confirm your zoning first.

Can I build an addition on the front of my Waukee house?

Yes, within a limit. Waukee’s zoning code checks the first building on each side within 200 feet. Your front addition cannot sit closer to the street right-of-way than the average of their front yards. The R-1 front yard minimum of 30 feet still applies too.

Will an addition make me add fire sprinklers in Waukee?

No. Waukee’s amended residential code says an automatic sprinkler system is not required for additions or alterations to existing buildings that do not already have one. Waukee’s sprinkler rule is aimed at new dwellings of 8,000 square feet or more.

Can I build an ADU or in-law suite in Waukee?

Iowa’s SF 592 opened that door statewide. An accessory dwelling can reach 1,000 square feet or half the size of the main house, whichever is larger. Cities may not require that the owner live there. We check Waukee’s zoning and your lot before drawing one.

Who checks the energy work on a Waukee addition?

Waukee does not do it in-house. Its 2012 energy code amendment requires a certified third party to complete energy inspections and send a report to the administrative official. We line up that inspector as part of the addition schedule.
