If you’re planning to build in Southern Colorado, one of the first things you’ll discover is that building permits are handled differently from county to county — even between neighbors like Custer County and Fremont County.
Many property owners moving into the Wet Mountain Valley or surrounding areas assume the process is standardized statewide. In reality, each county adopts and administers building codes locally to reflect terrain conditions, wildfire exposure, infrastructure access, and long-term planning priorities.
Understanding these differences early can help prevent delays, reduce redesign costs, and keep your project moving smoothly from concept to construction. Warren Gold, CEO Valor Development.
This video guide explains the real-world differences between Custer County and Fremont County permitting so you can plan ahead with confidence.

Why Permit Requirements Differ Across Southern Colorado
Colorado allows local jurisdictions to adopt building codes appropriate for their environment. Mountain terrain, wind exposure, snow loads, wildfire risk, and rural infrastructure all influence how counties review construction projects.
Most jurisdictions operate under versions of:
International Residential Code (IRC)
International Building Code (IBC)
International Energy Conservation Code (IECC)
Local adoption allows counties to address safety, durability, and performance expectations specific to regional conditions.
Colorado Department of Local Affairs:
Custer County Building Permit Overview
Custer County includes Westcliffe, Silver Cliff, Rosita, and surrounding mountain properties where building often involves rural land, varying elevations, and site-specific access considerations.
Custer County Planning & Zoning administers land use regulations, zoning compliance, and development standards.
Official Planning & Zoning Department:
Building permit and application information:
Town of Westcliffe:
Town of Silver Cliff:
Depending on project scope and property conditions, permit applications may involve:
site plan or improvement survey
structural drawings or engineered details
foundation design information
wastewater or septic approval if applicable
driveway or site access considerations
zoning compliance review
Requirements vary based on structure type, parcel characteristics, and applicable land use regulations. Applicants should confirm current submittal requirements directly with the county.
Because many parcels are undeveloped, additional planning considerations may include:
grading and drainage planning
snow load engineering
wildfire exposure zones
well and septic coordination
emergency vehicle accessibility
Early site evaluation helps identify potential constraints related to utilities, soil conditions, and access.
Fremont County Building Permit Overview
Fremont County includes Cañon City, Florence, Penrose, and surrounding areas where development patterns range from rural agricultural land to more structured residential zoning districts.
Fremont County provides detailed building permit information and application pathways through its Building Department.
Fremont County Building Department:
Applications and submittal information:
City of Cañon City:
Town of Florence:
Permit applications commonly include documentation appropriate to the structure type, which may involve:
building permit application forms
engineered structural drawings when required
plot plans showing setbacks and improvements
energy compliance documentation where applicable
septic approval if outside municipal sewer service
contractor registration verification
Fremont County publishes application pathways for common project types such as residential dwellings, accessory structures, agricultural buildings, and additions.
Specific requirements vary based on project scope and location.
Key Differences Between Custer County and Fremont County
Rural Mountain Conditions vs Structured Development Patterns
Custer County projects frequently involve:
larger rural parcels
off-grid or partially developed utilities
extended driveway access routes
higher elevation exposure
wildfire interface considerations
Fremont County projects often include:
established infrastructure availability
defined zoning districts
more standardized parcel layouts
structured development review pathways
Both counties require compliance with adopted building codes, but local environmental conditions influence how projects are evaluated.
Engineering and Planning Considerations
Engineering requirements are influenced by environmental factors such as:
snow load conditions
wind exposure
soil composition
site slope
wildfire interface location
Documentation requirements vary depending on the structure type and building classification.
Applicants should verify engineering requirements directly with the county prior to finalizing design plans. Or you can call us today to start your process.
Permit Timelines
Permit timelines vary based on:
completeness of submitted documentation
engineering complexity
project scope
site accessibility
department review workload
Submitting complete and accurate documentation helps reduce review cycles and revision requests. Valor offers turn-key services from site evaluation to final construction.
Common Permit Categories for New Construction
Permit pathways depend on project scope and structure classification.
Examples may include:
Residential Construction
primary building permit
foundation approval
wastewater or septic approval where applicable
electrical permit
plumbing permit
mechanical permit
Steel Buildings and Agricultural Structures
engineered structural permit when applicable
wind load and structural compliance documentation
slab or foundation review
Site Development
grading or earthwork permits
driveway or access permits
culvert or drainage review
erosion control considerations
Permit review helps ensure structures meet adopted safety and performance standards.
Planning Ahead Helps Avoid Delays
Permit requirements influence:
project timelines
engineering scope
site preparation strategy
design decisions
construction sequencing
Understanding jurisdiction expectations early can help reduce:
redesign costs
schedule delays
additional review cycles
unexpected engineering adjustments
Early coordination between owner, designer, and builder often results in a smoother process.
