Summary

Casper enforces blight and unsafe structures through the Uniform Code for the Abatement of Dangerous Buildings, 1988 Edition, adopted under Chapter 15.48. A licensed demolition contractor or the property owner must pull a city-issued demolition permit before tearing anything down, post the required bond, and comply with vacate notices the code requires to be posted at every exit.

F.Add Section 803. Permits Required (A). A demolition permit shall be obtained from the Building Official before any demolition or removal of the structure occurs. The permit must be obtained by a licensed demolition contractor or the owner of record of the property. However, the demolition permit will be valid for a period not to exceed ninety (90) days. The permit may be extended for a period of up to ninety (90) days providing the permittee can demonstrate that the demolition project is of sufficient size or scope that it will require additional time to complete the demolition project. ... G.Add Section 804. (A) Bonding Required. All permit applications must be accompanied by a performance bond, letter of credit or a form of collateral acceptable to the City of Casper to insure the timely completion of the demolition project. The amount of the surety will be based on twenty dollars ($20.00) per square foot of the building project area, including each floor and basement area to be demolished.

Full Breakdown

The City Council adopted the Uniform Code for the Abatement of Dangerous Buildings, 1988 Edition, under Wyoming Statute § 15-1-103(A)(XXVI) and (XLI), codified at § 15.48.020, then rewrote several of its sections to fit Casper. Section 302(16), amended by § 15.48.030(C), lets the fire chief classify a structure as dangerous for obsolescence, dilapidation, deterioration, damage, inadequate exits, insufficient fire-resistive construction, or faulty wiring, gas connections or heat apparatus. Once a vacate order issues, § 15.48.030(D) requires notice posted at every exit reading in part 'Do not enter unsafe to occupy.

It is a misdemeanor to occupy this building or remove or deface this notice,' signed by the City Manager. Before any demolition or removal proceeds, § 15.48.030(F) requires a demolition permit from the Building Official, defined by § 15.48.030(B) as the City Manager or an authorized representative, obtainable only by a licensed demolition contractor or the property's owner of record, valid for ninety days and extendable another ninety if the project's size justifies it. Section 15.48.030(G) requires every permit application to carry a performance bond, letter of credit, or acceptable collateral sized at twenty dollars per square foot of the demolished building area, counting every floor and basement.

Appeals of the Building Official's decisions go to a Board of Appeals of at least three City Council members, appointed by the Mayor with council consent, under the amended Section 205 in § 15.48.030(A). The City Engineer or Community Development Director must itemize the city's own repair or demolition costs and file that report with the Clerk-Treasurer, per § 15.48.030(H).

Violations & Fines

Violating any provision of the dangerous-buildings code is a misdemeanor under § 15.48.040, with every day the violation continues, is committed, or is permitted charged as a separate offense, punishable as set out in Chapter 1.28: up to a seven-hundred-fifty-dollar fine per offense. Occupying a building after a vacate notice has been posted, or removing or defacing that notice, is itself a misdemeanor under the posted-notice language required by § 15.48.030(D).

Frequently Asked Questions

What makes a building 'dangerous' under Casper's code?
Section 302(16), as amended by § 15.48.030(C), lets the fire chief flag a structure as dangerous for obsolescence, dilapidation, deterioration, damage, inadequate exits, insufficient fire-resistive construction, or faulty electrical wiring, gas connections or heating equipment. Any one of those findings can trigger a vacate order and, eventually, a city-ordered demolition.
Who can pull a demolition permit for a condemned building in Casper?
Only a licensed demolition contractor or the property's owner of record may apply under § 15.48.030(F), and the Building Official, who is the City Manager or an authorized representative, issues it. The permit is good for ninety days, with one ninety-day extension available if the project's scope justifies more time.
How big a bond does a Casper demolition permit require?
Section 15.48.030(G) sets the bond, letter of credit, or acceptable collateral at twenty dollars per square foot of the building area being demolished, counted across every floor and the basement. It has to accompany the permit application before the Building Official will approve it.
What happens if I ignore a posted vacate notice?
The notice itself, required under § 15.48.030(D), states that occupying the building or removing or defacing the notice is a misdemeanor. Combined with § 15.48.040's general penalty, that means fines under Chapter 1.28, up to seven hundred fifty dollars, with continued occupancy charged as a new offense each day.
