Golden's older blocks and newer edges
Golden dates to the 1859 gold rush and is the county seat of Jefferson County, so it has a deeper stock of old houses than most west metro suburbs. The blocks around downtown and Washington Avenue include late 1800s and early 1900s cottages, Victorian-era houses and small brick homes, many on narrow lots. The 12th Street Historic District is one designated concentration of them.
Streets near the Colorado School of Mines campus mix owner-occupied houses with student rentals. Farther from downtown, postwar and later subdivisions fill the north and south sides of town, often on sloped lots with walkout basements.
What older Golden houses need
Houses from the 1800s and early 1900s were built before modern foundations, insulation and wiring. Common findings are stone or brick foundations with no waterproofing, porches pulling away from the house, soft masonry joints that need repointing and add-ons from several decades that don't tie in well. Careful repairs and renovations often come before any remodel.
What changes in Golden
- 01
Register or local
National Register listing alone rarely limits private owners. Local historic designation is what triggers design review of exterior work.
- 02
Clear Creek floodplain
Lots near the creek can sit in a mapped floodplain. Check the FEMA map before planning a new home or a large addition.
- 03
Dipping bedrock
Steeply tilted claystone in parts of western Jefferson County can heave unevenly. A lot-specific soils report and engineered foundation are essential.
- 04
Winter wind
Strong downslope winds hit this side of the metro. Roof fastening, siding attachment and deck connections matter more here.
- 05
City or county
A Golden mailing address may be unincorporated Jefferson County. Confirm who permits your parcel first.
Golden permits, historic review and the Clear Creek floodplain
Inside city limits, building permits come from the City of Golden. Many properties with a Golden mailing address are unincorporated Jefferson County, and those go through the county. Check the parcel before anything else.
Historic status takes two forms. National Register listing, by itself, generally does not restrict what a private owner does with private money. Local designation is what brings design review of exterior changes. If your house is in or near a historic district, ask the city which applies before drawing an addition.
Clear Creek runs through the middle of town, and lots near it can fall inside a mapped floodplain. That can mean a floodplain permit and elevation requirements for new homes and for large remodels or additions. Check the FEMA flood map for the parcel early, because it can change what can be built and where.
Soils, slopes and wind on the west edge of the metro
Golden sits at the western edge of the metro, and the ground there is less predictable. In parts of western Jefferson County, layers of claystone bedrock tilt steeply, and where they contain swelling clay, heave can be severe and uneven. Jefferson County maps a designated dipping bedrock area for that reason. Any new home or addition here starts with a soils report and a foundation designed by an engineer for the specific lot.
Sloped lots add retaining walls, drainage and walkout details to the plan. Strong downslope winds are also common on this side of the metro in winter, so the city's wind design requirements, roof fastening and siding attachment deserve close attention. Our roofing, siding and windows page and our notes on where houses leak cover the details that keep weather out.
Home additionsNew space tied into the old structure so it looks and performs like one house.
Repairs and renovationsSmaller fixes and updates, starting with finding the cause, not just the symptom.
Custom homesA new house designed around its site, from soils report to final walkthrough.
Roofing, siding and windowsThe weather-facing shell of the house, flashed and lapped to shed water and hail.
Projects Golden homeowners ask about most
Small older houses on narrow lots lead to home additions, often a rear addition or a carefully scaled second story that respects the street. Infill and replacement lots lead to new custom homes designed around slope, floodplain and setback limits.
Nearby Lakewood and Arvada have mostly younger housing and their own permit offices, so their pages read differently.
Questions about building and remodeling in Golden
Do I need approval to remodel a historic house in Golden?
Interior work follows normal permitting. Exterior changes to a locally designated property or one in a local historic district generally need design review first. National Register listing on its own usually doesn't add review for privately funded work.
Can I build or add on in the Clear Creek floodplain?
Sometimes, with conditions. A floodplain permit and elevation requirements may apply to new homes and to large remodels or additions. Check the FEMA map and ask the city early.
Why do Golden foundations need a soils report?
Expansive clay soils and steeply tilted claystone bedrock occur in parts of western Jefferson County and can heave a foundation unevenly. A soils report lets the engineer design the foundation for the actual ground on your lot.
Who issues building permits for a Golden address?
The City of Golden for properties inside city limits, and Jefferson County for unincorporated parcels with Golden mailing addresses. County parcel records show which one applies.
