In Del City, the storm shelter permit is pulled by the installer, not the homeowner. The city issues it only to a contractor licensed with Del City. That contractor must keep a $5,000 bond in the city’s favor, renewed every year. The plans must also carry a registered professional engineer’s seal. So the company you choose brings both the credentials and the drawings.

Checking the company before you sign

The license and bond are the first two things to ask a Del City installer about, before price. Holding them shows the company is set up to work under Del City’s rules. Oklahoma has no state license for shelter installation, so the city license is the one that counts. Wiring for lights or outlets inside the shelter still needs a state-licensed electrician.

The form also puts the inspection calls on the contractor. Inspections have to be scheduled at least 48 hours ahead. A failed one can bring a re-inspection fee. Agree in writing who pays if one has to be repeated, and ask the company to send you each result.

You sign the application too. The owner’s section says that you, as the property owner, are “ultimately responsible for any work done on the premises.” That is a good reason to keep a copy of the issued permit with your house papers.

The engineer’s seal and the site plan

Del City asks for two documents beyond the form:

  • a digital site plan drawn to scale (a map of your lot). It shows the shelter, every other structure on the lot, and the distances to property lines and to those structures.
  • plans and specifications with the signature and seal of a registered professional engineer. They include a statement that the shelter meets the design requirements.

The site plan is drawn for your lot alone. Ask whether both are included in the price or billed separately. The 2024 form still names the 2015 International Residential Code (the home building code). The state adopted the 2024 IRC on September 14, 2026. The engineer can confirm with the city which edition applies.

Crutcho and Cherry creeks

Del City sits at the bottom of two drainage basins. The 2024 county hazard plan counts 1,354 parcels in FEMA’s high-risk flood zone, mostly along Crutcho and Cherry creeks. Lots in mapped flood areas fall in the city’s Flood Overlay District. Building there needs a Floodplain Development Permit, reviewed by the Flood Plain Manager. The city’s flood ordinance is stricter than the federal minimum. The county plan describes it as a 2009 higher-standards ordinance.

For a shelter, this changes the choice of type. A below-ground floodplain shelter is ineligible for SoonerSafe; an above-ground room may be eligible. Ask the installer to check your parcel on the flood map before quoting a buried unit. If the lot is mapped, ask it to price an above-ground option too.

Where it can go

The application offers back yard, front yard, side yard and garage floor, above or below ground. Above-ground units fall under Chapter 5, Article IX of the city code. Ask the company to confirm the setbacks and height limits for your exact spot before the engineer draws the site plan.

The county record and the warning system

The chart below covers all of Oklahoma County from 1950 through 2025. During 2016–2025, 2 tornadoes touching the county reached EF3 or stronger somewhere along their paths. Del City runs 8 outdoor warning sirens, tested at noon on Saturdays when the weather allows. They are meant for people outside, and the city says not to rely on them alone.

Rebates for Del City shelters

Del City once proposed a residential safe room rebate of its own and dropped it because the state already runs one. The state reports that the 2026 SoonerSafe program is not open as of October 29, 2026. So budget the shelter at full price.

After installation, register it through the form on the city’s Severe Weather Preparedness page. It asks where the shelter is on the property. It also asks about special hazards or needs, so rescue teams know what to expect.

Requesting a Del City quote

Ask for a quote from a company that holds the Del City license and bond. Ask for an on-site look at the lot, including the flood map for your parcel. The itemized price should name:

  • the engineer-sealed plans
  • the scaled site plan
  • the permit fee
  • dirt haul-off

The company should pull the permit and schedule the inspections.
