Johnstown home remodeling covers a town split between an early twentieth-century main street and new neighborhoods near the interstate. Johnstown lies mostly in Weld County with a portion in Larimer County, and its newest growth clusters around I-25 and U.S. Highway 34. This page covers the Town's permit process, the original town along Parish Avenue, the newer neighborhoods near the interchange, and what each tends to need in a remodel.
How the Town of Johnstown Handles Remodel Permits
Johnstown is a home rule municipality with its own Building Department, which administers the Town's adopted codes and issues residential permits inside town limits, on either side of the county line. Permit and contractor license applications are submitted through the Town's online self-service portal, and contractors need a Town license.
One local provision is worth knowing: a homeowner may pull a permit for work on their own owner-occupied primary residence without a contractor's license. Owner permits shift responsibility for code compliance and inspections onto the owner, which is a reasonable choice for a small project and a risky one for structural, gas or electrical work.
The I-25 and Highway 34 Corridor
The southeast quadrant of I-25 and Highway 34 holds the 2534 development, a roughly 600-acre master-planned area that includes the Johnstown Plaza retail center, anchored since 2017 by a large Scheels store. Northwest of town, Thompson River Ranch, near the Big Thompson River, has been building homes since 2005 and spans the Larimer and Weld county line. The first Thompson River Ranch homes are now about twenty years old, so original furnaces, water heaters and builder finishes from the early phases are reaching replacement age. Neighborhoods like these put new housing within a few minutes of the interstate, and they come with HOAs, builder-grade finishes and basements waiting for a plan.
Remodeling Homes Across Johnstown's Neighborhoods
The Original Town Along Parish Avenue
Harvey J. Parish platted Johnstown in 1902 along the Great Western Railway and named it for his son, John. Parish Avenue, the main street, still has much of its original architecture, and the blocks around it hold the town's oldest homes. Those houses bring the age-related checklist: lead paint before 1978, older wiring and plumbing, and framing that may not be square.
Established and Newer Subdivisions
Beyond the original town, Johnstown's housing is a run of subdivisions from different decades. Established neighborhoods include Pioneer Ridge and Rolling Hills. Newer ones include Thompson River Ranch, The Granary, Johnstown Farms and Revere.
| Area | Housing character | Common remodel focus |
|---|---|---|
| Original town near Parish Avenue | Early twentieth century and postwar | Systems updates, lead-safe demolition, kitchen and bath rebuilds |
| Established subdivisions | Late twentieth century | Opening floor plans, replacing original finishes |
| Newer communities near I-25 | Recent production homes | Basement finishing, builder-grade upgrades, HOA review |
Planning a Johnstown Remodel
In the newer neighborhoods, basement finishing in Johnstown is usually the first project, because the space is already there. Near Parish Avenue, an older house may need the order reversed: systems first, then a bathroom remodel or kitchen that the new wiring and plumbing can support. Our design and planning process sorts that order out before construction starts. For the regional picture, see the Northern Colorado remodeling overview; to the north, Windsor also straddles the county line, with its own permit office.
