Building and Zoning

The City of Colstrip has adopted regulations that help maintain the quality of life within the city. The zoning codes have regulations concerning land uses, building setbacks, storage and parking of vehicles and general property maintenance. These ordinances provide for the separation of incompatible land uses (industrial plants next to residential areas) and separation of buildings to enhance safety. They strive to protect the community from conditions of blight caused by overgrown weeds, junk vehicles, abandoned homes or accumulations of debris that may affect public health or create a nuisance within a community or neighborhood. Property conditions such as these can directly affect the neighborhood by lowering property values, attracting vermin and disease carriers such as rats, feral animals and mosquitoes as well as contribute to the decline of other property. It is the code officer’s job to help residents comply with zoning regulations or to determine if a permit is needed. Just call the Code Enforcement Office at 748-2300 ex. 2305.

RESIDENTIAL CONSTRUCTION
Residential building permits are available through the Building or Zoning Department at Colstrip City Hall. Building permits are required to ensure that building construction complies with the International Building Codes. Zoning permits are usually required with all building permits to ensure that setback requirements are met to protect public safety and property values. Many of these forms are available to you on line. The City of Colstrip requires that all construction be checked to make sure it complies with the international building codes. This service is provided at no additional cost to you for the protection of you and of your neighbors against potential structural problems that may arise during building construction. Call 748-2300 ex. 2305 to set up a time for the inspection. Be sure to allow two or three days advance notice so a time can be arranged for the building inspector to come out to check your site.

Moving a Mobile Home onto a Lot

When moving a mobile home onto a lot in Colstrip both a zoning permit and a building permit is required before a moving permit is issued. The total cost for these two permits is forty dollars.

The homeowner will be asked to complete a form called an Application for Building/Zoning Approval. This application asks that the homeowner look at his lot and determine the best possible way to orientate the mobile home on the lot to meet local district setback requirements and still allow for possible future expansion. The form asks for a diagram of the lot with the distance from each lot line to the mobile home clearly marked. When positioning the home please consider any plans for adding decks, porches or garages. These expansions must also meet the setback requirements for the neighborhood.

A description of how the mobile home will be set up will be necessary for the building permit. The building permit is to ensure that the mobile home is properly blocked or placed on a code compliant foundation. Please give us a call at 748-2300 two or three days in advance of the arrival of your trailer. That way a building inspector will be available to check the site for safety and code compliance.

The exception to this rule is for trailers being moved into the trailer court in the south end of Colstrip. Because of the size of the lots, trailers moved into this trailer court will only be required to complete a building permit that details proper blocking precautions to receive their moving permit. The fee for this permit is twenty five dollars. Trailers parked in the RV section of the court require no moving permit.

Our office will be glad to help you in this process. If you have any questions or concerns please contact us at any time. Office hours are from 9:30 a.m. to 1:30 p.m. Monday through Friday.
