Framing in Commerce City, CO

Framing is where a Commerce City remodel meets the city’s wind and snow design criteria directly. A new opening, an altered wall, or a basement layout is not just a carpentry decision here; it has to satisfy a wall-bracing standard the city built specifically around its adopted 115 mph design wind speed. Apollo Construction plans every Commerce City framing scope against that standard from the first sketch, not after the walls are already open.

Interior Alterations Fall Under the Same Residential Permit Path

Commerce City’s permit-required list covers interior alterations, including finished basements, as a broad category rather than singling out wall removal as its own line item. In practice, that means any interior framing change, removing a wall, widening a doorway, reconfiguring a basement layout, moves the project onto the city’s Residential Alteration (RALT) permit path, filed through eTRAKiT and reviewed through the same Gateway Review, Plan Review, and Pre-Issuance Review steps the city uses for other residential work.

Wall Bracing Is Not Optional on New or Altered Framing

The city publishes a dedicated Wall Bracing design guide built around IRC Section R602.10 and Commerce City’s 115 mph wind speed. Braced wall panels have to begin within 10 feet of each end of a braced wall line, be spaced no more than 20 feet apart, include at least two panels per line, and meet minimum cumulative lengths pulled from IRC tables based on building height and wall spacing. Acceptable methods include intermittent bracing, such as let-in bracing, wood structural panels, or gypsum board, and continuous sheathing, and the city allows mixing methods within the same braced wall line.

Plans submitted to the city have to clearly identify every braced wall line, every panel, and the method used at each one. The city also offers an interactive worksheet to help work through the prescriptive tables, and we use that same worksheet during design so the framing plan and the permit submission match from the start.

When a Project Needs an Engineer Instead of the Prescriptive Tables

Any design that departs from the prescriptive wall-bracing tables needs a detailed wind load determination, a detailed shear-wall design, connection analysis, and the original signature and seal of a Colorado-registered professional engineer. Pre-engineered bracing systems have their own path, requiring manufacturer documentation and an evaluation report rather than a stamped calculation. We flag early in design whether a project can stay on the prescriptive path or needs an engineer, because that decision affects both the drawing set and the schedule.

Snow, Wind, and Frost Numbers That Drive the Framing Design

Commerce City’s adopted local design criteria set the numbers every framing plan has to satisfy: a ground snow load of 35 psf, an ultimate design wind speed of 115 mph, Seismic Design Category B, a frost line depth of 36 inches, and a base elevation of 5,160 feet, with ice barrier underlayment required at eaves. Roof framing, header sizing, and any post or beam bearing on a footing all trace back to these figures, and we do not substitute a value from a neighboring jurisdiction even when the difference looks small.

Sealed Drawings and the Building Official’s Discretion

Sealed construction documents are not generally required for one- and two-family homes designed under the IRC, but the building official retains the ability to require sealed documents on a specific project. A framing plan that stays within the prescriptive wall-bracing tables and standard IRC framing provisions typically does not need a stamped set; a project that relies on custom beam sizing, an unusual opening, or an engineered bracing alternative is more likely to be asked for one. We treat that as a case-by-case determination rather than a fixed rule.

Temporary Support Before Anything Load-Bearing Is Cut

We did not find a Commerce City page that separately addresses temporary shoring or the sequencing for removing an existing bearing wall; the city’s guidance in this area is the general building-official discretion already noted above rather than a published shoring standard. In the absence of a city-specific shoring rule, we still support the structure before any load-bearing member is disturbed, transfer load to the permanent framing only once it is complete, and do not treat that sequencing as optional simply because the city has not published a separate document on it.

How We Sequence a Commerce City Framing Project

We start with the existing structure: joist and rafter direction, walls above and below, and any prior alteration that could affect the plan. Once the scope is set, we decide whether the bracing design can follow Commerce City’s prescriptive wall-bracing tables or needs an engineer’s stamped design, and we file the RALT permit in eTRAKiT with plans that identify every braced wall line and panel. Temporary support goes in before any bearing element is disturbed, permanent framing is installed to the city’s adopted snow, wind, and frost criteria, and the assembly stays open for inspection before insulation or drywall covers it.

Common Questions

Does removing an interior wall need a permit in Commerce City?
Yes. The city’s permit-required list covers interior alterations broadly, including a wall removal or layout change, and that work goes through the Residential Alteration permit process filed in eTRAKiT.

What is Commerce City’s design wind speed for framing?
The city’s adopted local design criteria set an ultimate wind speed of 115 mph, which is the basis for its Wall Bracing design guide and its prescriptive braced wall panel tables.

When does a framing project need an engineer instead of the standard tables?
Any design that departs from the prescriptive wall-bracing tables needs a detailed wind load determination, shear-wall design, connection analysis, and a stamped set from a Colorado-registered professional engineer.

What ground snow load does Commerce City framing have to be designed for?
The city’s local design criteria list a ground snow load of 35 psf, along with a 36-inch frost line depth and Seismic Design Category B.

Talk to Us About Your Project

Tell us which walls you want to change, add, or remove, what is above and below the area, and whether you already have plans or a past permit record for the home. We will work through Commerce City’s wall-bracing tables, identify whether the scope needs an engineer’s design, and prepare the RALT permit submission before any framing is disturbed.
