Oklahoma installer price lists checked in October 2026 put outdoor underground shelters at $4,200–$5,650 installed. They put above-ground safe rooms for 9–16 people at $6,250–$8,000 installed. For an underground shelter under the garage floor, national cost guides list $6,000–$15,000 installed.

Those installed prices cover the shelter and the work. Sprague’s Backhoe includes excavation for underground units and anchoring for above-ground rooms. CM Construction includes utility location and installation using on-site materials. The permit, dirt haul-off and delivery to your address are the items to check in each quote.

Where the numbers in the table come from

The table below mixes three kinds of price, and it helps to keep them apart.

Oklahoma installed prices come from Sprague’s Backhoe (Blanchard and Bridge Creek area) and CM Construction (Ardmore). Sprague’s installs underground units within about 60 miles of Blanchard. It advertises above-ground installation statewide, with delivery extra beyond 60 miles of Bridge Creek. CM charges a $200 surcharge for jobs 31–50 miles from Ardmore and does not go farther. In Tulsa or elsewhere outside those areas, treat these lists as a reference. Expect local installers there to quote their own figures.

Survive-a-Storm lists steel shelters at $3,995–$9,245 and panelized interior rooms at $5,670–$8,535. Ask what the price includes for your chosen model. The Extreme model page says:

  • installation is not included
  • delivery is priced by location
  • a concrete pad is needed

Add those costs before you compare a unit-only price with an installed one.

National and statewide guides supply the garage-shelter row and the “typical project” row. Angi’s Oklahoma range, updated September 2026, is $3,000–$8,000.

What changes the price

Size. On Sprague’s list, an outdoor slope-front shelter goes from $4,850 for a 6×8 to $5,650 for a 7×10. Its above-ground rooms run from $6,250 for a 5×7 (about 9 people) to $7,650 for a 7×9 (about 16 people).

Entry design. Entry options carry their own prices. Sprague’s “Easy Access” 6×8 is $5,250, against $4,850 for the standard slope-front of the same size. CM’s “EZ Entry” units are $300 more than its standard ones.

Yard or garage. Ask for the digging and any slab cutting or concrete work to be priced for your chosen unit.

Ground and access. HomeGuide notes that many companies include basic digging but charge extra for rocky soil or difficult installs.

Distance. Delivery charges and service boundaries vary, so compare totals for your own address.

Costs to confirm before you sign

The “Often extra” list under the table covers the permit, dirt haul-off, delivery, a concrete pad and separate anchoring. A few more items belong in the quote:

  • The engineered design. Moore’s permit application requires a signed and stamped engineer design. Norman requires an engineer drawing that references ICC 500. Tulsa requires engineered stamped plans. Ask whether the installer supplies them and whether they are in the price.
  • Delivery and installation billed separately. If a seller quotes the unit alone, Angi puts delivery plus installation at $1,000–$3,000.
  • Electrical work. Lights or outlets in the shelter need a state-licensed electrician.
  • Outdoor site work. In Tulsa an outdoor shelter also needs grading and drainage and erosion-control plans. Ask the installer about Yukon’s dirt haul-off deadline.

Permits: who pulls them and what they cost

In some cities the installer has to handle the permit. Bartlesville issues storm shelter permits only to the licensed contractor hired to install the shelter. In Del City, the contractor obtains the permit and calls for inspections, and it must be licensed with the city. Elsewhere it varies. CM Construction’s list leaves permits to the homeowner. Ask each company which permit it will pull and to put the fee in the written quote.

These listed fees come from each city’s documents, checked in October 2026.

City Listed fee What it is based on
Moore $34.50 $30 city fee plus $4.50 state fee, fee schedule updated March 2025
Norman $54.50 in the April 2025 FAQ $50 city fee plus the state fee in that document
Tulsa $88 indoor, $132 outdoor, plus a $4.00 state fee Ordinance No. 25351, approved July 24, 2024
Oklahoma City Permit required; ask the installer to put the fee in the quote City storm shelter permit page

Norman’s April 2026 fee summary lists a different state add-on; ask the installer to confirm the shelter permit total.

The SoonerSafe rebate and its 2026 status

As of October 2026, Oklahoma Emergency Management (OEM) says the 2026 SoonerSafe program is not open. The most recent cycle was 2025. It gave priority to homeowners in counties covered by the 2024 disaster declarations, including McClain and Pottawatomie. The rules allowed a drawing for other counties only if money remained. The program depends on FEMA hazard mitigation funding, so OEM runs it only when federal money is available.

When a cycle is open, the rules are:

  • The rebate is up to $3,000 per home and no more than 75% of the actual cost. On a $3,000 shelter that means at most $2,250. On anything over $4,000, the $3,000 cap applies.
  • You register online during the open period and must register again each year.
  • You must own the home, and it must be a single-family primary residence. Renters, duplexes and apartments do not qualify. Mobile-home owners qualify only if they also own the land.
  • A shelter put in before notice of selection is not eligible. Neither are retrofits, repairs of old shelters or do-it-yourself installs.
  • SoonerSafe requires compliance with FEMA P-320, FEMA P-361 and ICC 500. This is shown by a SoonerSafe Certificate of Installation that the installer signs.
  • In a floodplain, a below-ground safe room is not eligible, but an above-ground one may be.
  • The shelter must be in an interior first-floor room, underground, or detached within 100 feet of the home.

For budgeting, price the shelter on its own and treat the rebate as a possible later payment. The rebate is uncertain in both timing and selection.

How to compare quotes

Put the quotes side by side on the same terms:

  1. Same size and capacity. A 6×8 and a 7×10 are different products.
  2. Installed or unit only. Add delivery, a pad and installation to any unit-only price.
  3. Line items. Check digging, dirt haul-off, anchoring, the stamped engineer design and the permit fee.
  4. Local licensing. Oklahoma has no state license for shelter installers, but cities can require one. Del City, for example, requires shelter contractors to be licensed with the city.
  5. Warranty in writing. CM Construction’s list includes a 10-year seam-leak warranty. Compare what each quote actually covers.

Getting quotes for your address

Use the quote form to request a local site assessment and an itemized installation price. Ask each company to confirm permit handling in writing. To compare the quotes, ask each one for:

  • the type and size
  • what is included in the installation
  • the permit fee as a line item
  • delivery to your address
  • the written warranty terms
