Framing in Lone Tree, CO

Framing is the point in a project where design meets Colorado’s climate, and where the City of Lone Tree’s adopted structural criteria actually get applied. Whether it’s a new header for a wider opening, a wall coming out, or a full addition frame going up, the same permit process and the same design numbers govern the work. We work from those numbers rather than a generic national default, because Lone Tree’s adopted values are specific to this part of the Front Range.

Framing Runs Through the Standard Building Permit

The City’s permit rule covers any project that will “construct, enlarge, alter, repair, move, demolish, or change any building or structure,” and structural framing work falls squarely inside that language. A separate, distinctly named “structural alteration” or “wall removal” permit category does not appear to exist on the City’s published permit pages; in practice, framing changes go through the standard building-permit and plan-review process, with the scope described accurately on the application so the plan reviewer can evaluate what’s actually changing.

Whether a bearing wall removal requires a stamped engineer’s letter is not spelled out as a fixed rule on a public checklist; it is applied at the Building Official’s discretion based on the scope submitted. We assume engineering review is likely for any bearing element and build that into the schedule rather than treating it as optional.

The Structural Design Numbers Lone Tree Has Adopted

The City’s adopted residential design criteria set the structural targets every framed assembly has to meet: a ground snow load of 30 psf, a wind speed of 115 mph (Vult, Exposure C), Seismic Design Category B, a weathering classification of Severe, a frost line depth of 36 inches, and a winter design temperature of −3°F. Ice barrier underlayment is also required under the adopted criteria. Every header, rafter, and connection we spec for a Lone Tree project is checked against these figures, not a generic default.

Live load requirements follow the same adopted table: roof live load of 30 psf, dropping to 10 psf for attic space without storage or 20 psf where limited storage is allowed for, and residential floor live load of 40 psf, reduced to 30 psf in sleeping areas. Where a framing plan calls for a larger opening or a longer span than the existing structure was built for, these are the loads the new member has to carry.

When a Foundation Change Enters the Picture

If a framing project also touches the foundation, an amendment to the adopted residential code requires that the foundation inspection be performed by a Colorado-licensed professional engineer or a Colorado-registered architect, who provides a stamped written report to the Building Official. This requirement is documented in the context of additions, and we confirm its applicability with the Building Division for any framing scope that reaches the foundation, rather than assuming it applies uniformly to every project.

The adopted code edition behind these criteria is the 2021 International Residential Code, applied with local amendments under Ordinance 22-07. Where a design value or a code section is under active revision, we confirm the current figure with the Building Division before finalizing engineering, since a published guide can lag a recent adoption.

Business Licensing and Use Tax

Lone Tree’s Building Division does not issue or require a contractor license; what it does require is a valid City of Lone Tree business license, a $10 initial fee with no expiration or renewal charge, for every party listed on the permit before that permit is issued. The City also collects a 2.5% use tax on construction materials before permit issuance, which applies to a framing project the same as any other permitted building work.

Plan review and permit fees for framing scopes are calculated from project valuation using the City’s standard fee tables, the same tables used for additions and remodels generally. We build an accurate valuation into the estimate early so the permit line item reflects the real scope rather than a placeholder number.

Site Conditions and Working Hours

Framing work, particularly on an addition, is exterior work for scheduling purposes and follows the City’s standard construction hours of 7:00 a.m. to 7:00 p.m. on weekdays and 8:00 a.m. to 6:00 p.m. on weekends and state holidays; interior framing follows the broader 7:00 a.m. to 9:00 p.m. window. Every site also needs approved sanitation facilities and a trash or debris enclosure within 300 feet of the work, kept clear of the right-of-way unless Public Works has approved otherwise.

Before any excavation tied to a foundation or footing change, we request a utility locate through Colorado 811 so buried lines are marked ahead of digging. On sites with an active HOA, and Lone Tree notes that nearly every neighborhood has one, a framing change that alters roofline, footprint, or exterior massing is a common design-review item, so we raise it with the homeowner early.

How We Sequence a Lone Tree Framing Project

We start with the structural scope: what’s being removed, what’s being added, and what has to carry the resulting loads under the City’s adopted snow, wind and seismic criteria. Where the scope touches a bearing wall or the foundation, we get engineering involved before the permit application goes in, so the plan reviewer is looking at a complete, stamped package rather than a partial one that generates review comments and delays.

Once the permit is issued, we open the work area, confirm existing conditions match what the drawings assumed, and frame in the sequence that keeps the structure stable at every stage, temporary shoring where a bearing wall comes out, new headers and posts set before old framing is removed, and connections tied down to the loads they’re designed for. We call for inspections at the points the Building Division requires before the work is covered, and we don’t move to drywall or finishes until framing has passed.

Common Questions

Do I need a permit to remove a wall in my Lone Tree home?
Yes, structural changes including wall removal fall under the City’s building permit requirement, which covers any project that alters a building or structure. There isn’t a separate, distinctly named permit category for wall removal; it’s handled through the standard building-permit and plan-review process.

What snow and wind loads does Lone Tree framing have to meet?
The City’s adopted residential design criteria set a ground snow load of 30 psf and a wind speed of 115 mph (Vult, Exposure C), along with Seismic Design Category B, a 36-inch frost depth, and a −3°F winter design temperature. These are the numbers new framing has to be engineered against.

Will I need an engineer for a bearing wall removal?
Lone Tree doesn’t publish a fixed threshold for when a stamped engineer’s letter is required for a bearing-wall change; it’s applied at the Building Official’s discretion during plan review. We treat engineering as likely for any bearing element and build it into the schedule from the start.

Does a foundation change need a special inspection?
Where framing work touches the foundation, an amendment to the adopted code requires the foundation inspection to be performed by a Colorado-licensed engineer or registered architect, who provides a stamped written report to the Building Official. We confirm this requirement applies to the specific scope with the Building Division before proceeding.
