Building Permits & Inspections
Community Development staff can not answer questions about the requirements of the building code, overview passed/failed inspections, or explain building inspection requirements. If you need to talk directly to a building inspector or plan reviewer, you must call (877)840-6041 and leave a message with your permit number, project address, and contact information to be followed up with. Allow up to 2 business days for a response. Building officials can not provide consultation or design advice. If you need assistance with designing your project we encourage you to contact a licensed Colorado Engineer or Architect.
Inspections are done on Monday and Wednesday only. They must be requested online through your permit application on our online portal. You must request an inspection online by 5pm the day prior to inspection. You will be given a time for inspection the morning of the inspection which will show up on the online portal. The inspector will arrive within 2 hours of this window. If your inspection has been scheduled in the portal do not contact office staff until 2 hours after the inspection window for failure to show.

Processing & Plan Review Time
Please be advised that processing times for building permits have increased. New single family dwellings can take 8-12 weeks from application. Other permits can take 4-8 weeks from application. If you fail to provide complete plans, if plan changes are required, this will increase your permit processing time. Please plan your project accordingly. If you start work without a permit, you will be subject to an enforcement action.
Design Criteria (Climate & Geographic Minimum Standards)
Contractor Registration Required
Contractors must provide proof of passing score for applicable ICC exam or have a valid license from another ICC jurisdiction.
Electrical and Plumbing Permits
All electrical and plumbing permits in unincorporated Gilpin County are now being issued by the county effective March 1st, 2023. If you have an active permit issued by the State, you will continue and complete your existing permit with the State.
Electrical Utility Meter Release for United Power or Xcel Energy
To obtain a meter release you need to pull an electrical permit, have a qualified electrician inspect the work or electrical connected to the meter, then request a meter release inspection online through your permit application. Once that inspection is complete, we will send notice to release the meter to either Untied Power or Xcel Energy.
Building Permit Fees
Building Permits Required
Construction of any primary structure whether it be residential or commercial requires a building permit regardless of size. Most vacant land in Gilpin County is zoned RR, Resource Residential or RS, Residential Subdivision. Vacant, residentially zoned land, requires the construction of a primary structure prior to the construction or placement of any accessory structure(s). For residentially zoned land, a primary structure would be a single family home.
An accessory structure is a structure on the same property as a primary structure and the use of which is incidental to the use of the primary structure such as a garage, storage shed, or greenhouse. A permit is required for any accessory structure that is to be used for habitation of any kind regardless of the size of the structure. Accessory structures below 200 square feet that are not used for habitation (i.e. cooking, sleeping, bathrooms), do not require a building permit but still must meet all zoning regulations and developmental standards such as property line setbacks.
