Framing in Idaho Springs, CO

A framing project in Idaho Springs almost always starts inside a house that predates most modern code, on a lot shaped by a mining-town street grid rather than a modern subdivision plan. Apollo Construction reads the existing building first — joist direction, bearing lines, prior alterations — before deciding what a proposed wall, opening, or addition actually requires, and we plan the City’s permit path alongside that structural read rather than after it.

Structural Work Falls Under the City’s General Permit Rule

Idaho Springs’ rule is broad: no structure may be erected or altered until the City has issued a building permit. Framing changes — a removed wall, a new opening, an added room — sit squarely inside that rule, and there is no separate carve-out for framing as a stand-alone trade.

Remodels and Additions Go Through Plan Review

A framing scope tied to a remodel or addition is submitted using the City’s Residential remodel/addition checklist, which routes the project to plan review rather than the smaller One Stop Permit track reserved for single-trade, minor work. That distinction matters for scheduling: a wall removal or new opening needs its documents reviewed before a permit is issued, not picked up over the counter the same day.

The Governing Code Is the 2018 Edition, Not a Newer One

Idaho Springs has adopted the 2018 International Building Code and the 2018 International Residential Code, with local amendments in Municipal Code Chapter 19, and that is the edition that governs header sizing, prescriptive framing tables, and structural provisions inside city limits. Online span calculators and supplier literature increasingly reference newer code cycles by default, so we anchor framing decisions to the 2018 edition of record rather than to whatever edition a tool happens to assume.

Snow and Wind Loads Are Confirmed for the Actual Elevation

Colorado jurisdictions reference the Structural Engineers Association of Colorado’s published Colorado Design Snow Loads document as the source for ground snow loads by location, but the enforceable figure for a given roof or addition is whatever value the local jurisdiction adopts for that address. Idaho Springs sits well above 7,000 feet in a narrow canyon, and a specific psf ground-snow-load or wind-speed figure that the City currently enforces was not independently verified on an official Idaho Springs page in this pass. We do not borrow a number from a lower-elevation Front Range city or a generic state map; we confirm the applicable design values with the Building Department and SAFEbuilt, the firm that provides the City’s technical plan-review support, before finalizing a structural design.

Engineering Is Confirmed Before Material Is Ordered

A published Idaho Springs checklist stating exactly when a wall-removal or beam-replacement scope needs a stamped engineer’s letter versus prescriptive framing was not located in this pass. As a general matter, engineering becomes necessary once a scope exceeds what the adopted code’s prescriptive tables cover, and we treat that as the working assumption rather than a guess: any opening, beam, or post that looks close to that line gets a design-professional review before lumber is cut, and we confirm the specific trigger with the Building Department or SAFEbuilt rather than assuming a home’s age or size settles the question.

Working Inside a Mining-Era Building Envelope

Many Idaho Springs homes were framed long before current bearing-wall or connection practices existed, so a wall that looks decorative on a floor plan can be carrying real load, and a wall that looks structural can be a later, non-bearing partition. We expose enough of the assembly to read it honestly before committing to a design, and where the existing framing is out of square or irregular — common in a building this age — we plan the transition to new work deliberately instead of forcing new members to hide the difference.

How We Sequence an Idaho Springs Framing Project

We start with a site read of the existing structure and a plain description of the proposed change, then confirm with the Building Department whether the scope routes through the Residential remodel/addition checklist. We design to the City’s adopted 2018 code rather than a newer default, and we confirm ground snow load, wind design values, and the engineering-review threshold with the Building Department or SAFEbuilt before finalizing headers, beams, or connections. Temporary support goes up before any bearing element is disturbed, and the wall stays open long enough for trade coordination and any required inspection before it is closed. That sequence is what keeps a structural change in a century-old Idaho Springs house from becoming an unplanned discovery mid-project.

Common Questions

Does removing an interior wall in Idaho Springs need a permit?
Yes. The City’s general rule is that no structure may be altered until a building permit is issued, and a wall removal tied to a remodel is submitted through the Residential remodel/addition checklist for plan review rather than picked up as minor over-the-counter work.

Which code edition governs framing work in Idaho Springs?
The City has adopted the 2018 International Building Code and 2018 International Residential Code, with local amendments in Municipal Code Chapter 19. We design headers, beams, and connections to that edition rather than to a newer default a calculator or supplier guide might assume.

What snow load does Idaho Springs framing need to be designed for?
Colorado jurisdictions reference the Structural Engineers Association of Colorado’s snow-load publication, but the enforceable figure is whatever value the City adopts for the specific address and elevation. We confirm that figure with the Building Department or SAFEbuilt rather than assuming a number from a lower-elevation city.

When does a framing change need a stamped engineer’s letter?
Generally once the scope goes beyond what the adopted code’s prescriptive tables cover. A published Idaho Springs-specific threshold checklist was not located, so we confirm the trigger for a given opening, beam, or post with the Building Department or SAFEbuilt before ordering material.

Talk to Us About Your Project

Tell Apollo Construction the address, the rooms involved, what you want to change, and what sits above and below the area. Photos of the full wall or opening, adjoining rooms, and any visible cracking or prior alterations help us form an initial read before we confirm the permit path and design values with the City.
