What the Altus application asks for

Planning & Development handles the application review. Have the installer prepare the signed application for email submission. For a shelter, the form asks for:

engineering specifications, built to FEMA 320 and ICC/NSSA 500
the shelter’s total square footage
the floor type: concrete or ground
attached drawings

The office section includes zoning and setback checks and a place for the Fire Marshal’s approval. Have the installer confirm the city and state fees and list them separately in the written quote.

The form lists foundation, framing and final inspections. Have the installer identify which stages apply to your shelter and who will request each inspection.

Where a yard shelter can go

The application tells you to call OKIE, Oklahoma’s call-before-you-dig service, before any digging. The city’s posted 2008 development code gives these general rules for detached structures:

not in front of the house or in the required front yard
in the rear yard, at least 1 ft from an alley or easement on lots under 15,000 sq ft
10 ft from the rear line on lots of 15,000 sq ft to one acre
no taller than the house

Have the installer confirm current placement rules for your shelter and mark the approved spot on the drawings.

Flooding is the other check. The development code requires a separate floodplain permit for construction in flood hazard areas. The county’s draft hazard plan names several Altus flood spots. They include Broadway St east of Veterans Dr. and Deer Run and White Tail Circle in Hunter Pointe. Parts of the English Village and Presidents additions are on the list too. The city’s online GIS map shows flood zones by lot. If yours is in one, ask the installer to review placement and price an above-ground safe room.

Jackson County’s tornado record

The chart below covers tornado paths that touched Jackson County. The strongest in the 1950–2025 record was the EF4 of November 7, 2011. The draft hazard plan also lists an EF0 at Altus on May 9, 2013 and an EF3 near Elmer on May 16, 2015.

For warning updates, sign up for the city’s emergency alert system and follow National Weather Service instructions.

Registering the shelter

The fire department’s form is online. It asks for:

the shelter type: basement, safe room or cellar
the year it was finished
whether it is inside the house
whether emergency supplies are stocked
any special medical needs

The draft county plan describes a database of private shelters reported by owners in Jackson County towns. Submit your completed shelter’s details rather than assuming the permit registers it for you.

Choosing a shelter for an older Altus house

For an older Altus house, ask how the installer will check the garage slab before setting a unit there. Bring any plans or records of past work on the house. Have the installer explain whether its proposed unit needs changes to the slab and price those changes separately.

Altus has a city contractor license application. As of October 2026, it lists $250 for a new license and $50 for renewal. Oklahoma has no state license for shelter installers, so ask which city licensing requirements cover the job. Wiring for lights or a fan needs a state-licensed electrician.

Keep the shelter’s size and completion records for the property-tax exemption described in the FAQ.

Getting an Altus quote

Use the form below to ask for a free quote from an installer who works in Altus. Say whether you are thinking of the garage or the yard. A useful quote then includes:

a visit to compare the garage and yard locations
the engineering specs and drawings the city asks for
the permit filed by the installer, with the city and state fees listed
itemized prices for delivery, dirt haul-off and anchoring

Questions to ask a shelter installer

Can you show written proof that this shelter and its door meet ICC 500 and FEMA P-361?
FEMA does not certify products and says a seller's claim of meeting these criteria should be backed by independent testing or engineering. FEMA P-320 (2021)
How will it be anchored, and is my slab strong enough for it?
FEMA notes that many prefabricated safe rooms end up on slabs without enough reinforcement, which undermines the protection they are built for. FEMA P-320 (2021)
Who gets the city permit, and can I see it before work starts?
Oklahoma's Construction Industries Board tells homeowners to see the building permit before letting work begin. Oklahoma CIB, Home Repair Tips
Will you register the shelter with the city, or should I?
FEMA advises registering the exact location of the entrance with local officials right after installation, so rescuers can find it if debris blocks the exit. FEMA P-320 (2021)
For a below-ground unit: is my lot in a flood zone, and how will water be kept out?
ICC 500 does not allow below-ground shelters in mapped flood hazard areas, and FEMA recommends a sump pump inside in-ground units. FEMA P-320 (2021)
If I want the SoonerSafe rebate, should I wait until I am selected?

The FTC advises against paying the full amount up front and against making the final payment before the work is done. FTC, How To Avoid a Home Improvement Scam

Frequently asked questions

Do I need a permit for a storm shelter in Altus?

Yes. The city's building application lists Storm Shelter as its own permit type. Planning & Development reviews it. Ask the installer to file it and show you the permit before work starts.

How much is the storm shelter permit in Altus?

The application has one line for the shelter fee and one for a state fee, but no amounts are printed on it. Fees are not refundable. Ask the installer to confirm both and put them in the written quote.

How do I register my shelter with the Altus Fire Department?

Fill in the Safe Room/Cellar Registration Form on the city website. It is free and voluntary for homes inside city limits. The city uses the list only after storm damage, so rescuers know where to look.

Can Altus homeowners get the SoonerSafe rebate?

As of October 2026, SoonerSafe's 2026 program is not open. Jackson County received priority in the 2025 cycle. The published rules cap the rebate at $3,000 or 75% of actual cost, whichever is lower. Wait for selection before installing if you want to qualify.

Does a shelter lower my property tax in Jackson County?

As of October 2026, the exemption covers up to 100 square feet of a shelter added after January 1, 2002. You must own the property on January 1 of the tax year. Unless the assessor has already recorded the shelter, file OTC 905 by March 15 for that year's exemption. It ends when ownership changes.

Will the Altus sirens tell me when it is safe to come out?

No. The city says there is no all-clear signal. Emergency Management or 911 staff activate the sirens. Follow National Weather Service and local emergency instructions during a warning.
