For a storm shelter in Seminole, plan the location and ask the installer to settle the permit before work starts. Once it is installed, use the city’s Map My Shelter form to record its location.

How the Map My Shelter form works

The city’s Emergency Management page links an online form called “Map My Shelter.” The Fire Department page and the city home page point to it too. It asks for:

  • your name, address and phone numbers
  • the shelter type: above ground, below ground or inside the house
  • a pin on a map, placed as precisely as you can
  • how many people the shelter holds
  • a short note on where it sits on the property

The city says the answers are for emergency management only and are not public. Fill it in once the shelter is in, or ask the installer to do it as part of the job. The same page has a sign-up for emergency updates and recruits storm spotters.

Filing the building permit

Seminole’s permit page says building permits cover building, enlarging or altering a structure. Applications are taken in person at the Community Development Office. The application asks for the property owner, the location, the type of improvement, a drawing of it and its cost. As of October 2026, Seminole bases the permit price on the type of improvement.

The one-page form has lines for a plan review fee and a building permit fee. It also asks for a builder’s license number and the architect or engineer on the job. Building inspections are done by the city’s Code Enforcement team. Ask the installer to confirm the permit for your shelter and to put the fee in the written quote.

Wiring and the city’s contractor list

A light, an outlet or a vent fan in the shelter is electrical work. As of October 2026, electricians pay $200 a year to register with Seminole. They bring a copy of their state license and proof of liability insurance. The city’s “Are They Licensed” page lists registered contractors by trade, so you can look up the electrician named in a quote.

Tornadoes in Seminole County

Three tornadoes that crossed Seminole County were rated F4 along their full paths. They occurred on September 14, 1957, May 4, 1960 and May 17, 1981. Use the county chart below as background when comparing shelter options. The Seminole County storm shelter page has more on the county. For warnings, follow the National Weather Service and the city’s Emergency Management office.

Magnolia Creek and below-ground units

Magnolia Creek and its floodplains run through the middle of Seminole, according to the city’s 2012 long-range plan. That plan also records the city’s participation in the National Flood Insurance Program. Its Maps page links an online flood plain map. Look up your lot there before settling on a below-ground shelter. On a floodplain lot, SoonerSafe, the state rebate program, will not fund a below-ground unit. An above-ground safe room may still qualify.

The Census estimates that only 395 Seminole housing units were built in 2000 or later. If you want a unit in the garage floor or bolted to the slab, ask how the installer will judge an old slab.

What to put in a Seminole quote request

Send the form below for a free quote from an installer who works in Seminole. Tell the installer which type you are leaning toward and whether your lot is near the creek. Ask for a quote that covers:

  • an on-site look at the spot
  • any permit needed, filed at Community Development, with its fee on a separate line
  • the registered electrician, if the shelter gets wiring
  • delivery, dirt haul-off and any pad or anchoring
  • who fills in the Map My Shelter form
