In Colorado Springs, you may need a structural engineer when a project changes how a building carries loads, involves a new or modified foundation, addresses significant structural damage, or requires engineered plans for permitting. Common examples include home additions, load-bearing wall changes, certain decks and retaining walls, foundation problems, and new residential construction.
When is a structural engineer needed in Colorado Springs?
You typically need a structural engineer when your project changes an existing structural system, introduces new structural loads, requires foundation design, or raises a concern about the building’s structural condition.
Here are seven situations where structural engineering commonly becomes part of a Colorado Springs residential project.
1. You are building a new home, ADU, or residential structure
New residential construction requires a coordinated structural system that safely transfers loads from the roof and floors down through the walls, beams, columns, and foundation.
Depending on the project, structural engineering can include:
- Foundation design
- Floor framing and joist systems
- Beams and columns
- Roof framing
- Bearing walls and connections
- Lateral load-resisting systems
- Structural details required for construction
- Coordination with architectural plans
Foundation design is especially important because the appropriate system depends on the building as well as site-specific conditions. An engineered foundation should not simply be copied from a nearby project without considering the actual structure and available geotechnical information.
For custom homes, ADUs, accessory structures, and multi-family residential projects, coordinating architecture with structural engineering and foundation design early can reduce handoffs between disciplines and help avoid conflicts that are harder to resolve once the plans are nearly complete. We provide architecture, structural engineering, foundation design, and MEP services as part of an integrated residential design approach.
2. You are adding onto your home
Home additions often involve structural engineering because the new construction has to work with the existing home.
The engineer may need to address a new foundation, altered roof framing, new beams, larger wall openings, changes to floor framing, and the connection between the original building and the addition.
For example, suppose you want a new family-room addition with a wide opening through the home’s existing exterior wall. That exterior wall may currently support the floor or roof above it. Removing a large portion of the wall changes the load path, meaning the route structural loads take on their way to the foundation.
A structural engineer may design a beam over the new opening, determine where posts or bearing points are needed, and verify that the structure below those concentrated loads can support them.
Getting structural input while the layout is still being developed is usually more efficient than completing the architectural design and discovering later that the preferred opening, roof configuration, or foundation layout needs to change.
3. You are removing or modifying a load-bearing wall
A structural engineer is commonly involved when removing or altering a load-bearing wall. The engineer can determine how the existing loads should be supported and design the necessary beam, posts, connections, and supporting elements so the modified structure maintains a continuous load path.
A load-bearing wall supports more than its own weight. It may carry loads from a roof, floor, wall, or combination of structural components above it.
Removing that wall does not eliminate those loads. They must be transferred somewhere else.
Depending on the existing construction, the solution could require:
- A properly sized beam
- Posts at one or both ends of the beam
- Connections between the new structural members
- Verification of bearing conditions below
- Additional foundation support where new point loads are created
Do not assume a wall is non-load-bearing based only on which direction it runs. Framing layouts, trusses, beams, previous alterations, and bearing conditions can make two otherwise similar homes structurally different.
How can you tell if a wall is load-bearing?
Please always defer to a structural engineer for this one. The engineer can use multiple methods to figure out if a wall is bearing structure above. Determining whether a wall is load-bearing may require reviewing existing plans and checking the framing above and below the wall. Attic, crawl-space, basement, or exposed framing conditions can also help establish how loads move through the structure.
If the structural role is uncertain, confirming it before demolition is far safer and usually less disruptive than discovering a structural problem after the wall has been removed.
4. You see signs of possible foundation or structural movement
Consider contacting a structural engineer when foundation concerns are accompanied by significant or widening cracks, noticeable floor movement, sticking doors or windows, displaced foundation components, or other signs of structural movement. Not every crack is structural, so the location, severity, progression, and underlying cause matter.
Conditions that may justify a professional structural evaluation include:
- Significant cracks that appear to be widening
- Diagonal cracking around doors or windows
- Noticeably uneven or sloping floors
- Doors or windows that begin binding unexpectedly
- Separation between walls and ceilings
- Visible displacement of foundation walls
- Sagging or movement in structural framing
- Multiple symptoms appearing together or progressing over time
Cracks alone do not prove that a foundation is failing. Concrete, drywall, wood, and other building materials can crack or move for many reasons.
The engineer’s job is to evaluate the structural condition rather than diagnose a building from one isolated symptom. That distinction is particularly important before committing to an expensive foundation repair proposed without an independent engineering evaluation.
5. You are building or modifying a deck
A deck may require engineering depending on its size, configuration, attachment, loading, and permitting requirements.
Important structural considerations can include the ledger connection to the house, beam and joist spans, post locations, footing design, lateral stability, elevated conditions, and loads from a roof or cover.
Pikes Peak Regional Building Department maintains specific residential deck plan-review requirements, which is a good reason not to assume that every deck follows the same documentation path. Project-specific requirements should be confirmed before design and construction proceed.
For unusual layouts, long spans, elevated decks, covered decks, or configurations outside prescriptive requirements, structural engineering can establish a practical framing and foundation solution that gives the contractor clear information to build from.
6. You are constructing a retaining wall
A retaining wall becomes a structural problem when it must resist significant soil pressure or additional loads behind the wall.
The design can be affected by:
- Wall height
- Soil properties
- Drainage
- Ground slope
- Buildings or structures nearby
- Driveways or other loads behind the wall
- Overall site geometry
A surcharge is an additional load applied to the retained soil, such as a nearby structure or other loading above the wall. Surcharges can substantially change the forces the retaining wall must resist.
A structural engineer will be required for most retaining wall design. Some building jurisdictions have allowances for shorter walls, for instance, Pikes Peak Regional Building Department only requires engineering for walls support more than 4’ of soils. It is not a bad idea to consult with a structural engineer on any retaining wall application so you can be certain they won’t fall over with time.
7. An inspector, contractor, architect, buyer, or lender identifies a structural concern
You may also need a structural engineer because another professional has found a condition that requires more focused structural analysis.
Common examples include:
- A home inspector identifying unusual foundation or framing conditions
- A contractor discovering unexpected framing after demolition
- An architect needing structural design for a proposed layout
- A permit reviewer requesting additional structural information
- Damage following a fire, impact, or severe weather event
- A buyer wanting a structural condition evaluated before purchasing a property
- A contractor needing engineered details to complete construction
A general home inspection and a structural engineering evaluation serve different purposes. An inspector may identify symptoms that warrant additional review, while a structural engineer can evaluate the structural system and determine whether design, repair recommendations, or additional investigation is appropriate.
Why Colorado Springs projects can require site-specific structural engineering
Structural engineering in Colorado Springs should account for the actual building, property, and applicable local requirements rather than relying only on standardized details or rules of thumb.
Local permitting requirements
Pikes Peak Regional Building Department handles plan review, permitting, and inspections for Colorado Springs and other participating jurisdictions in El Paso County and the surrounding region.
What must be submitted depends on the project. Engineered documents may be required based on the scope, structural system, or conditions involved.
Homeowners and contractors should confirm current requirements for the specific project instead of assuming that every addition, deck, retaining wall, or foundation follows the same permitting rules.
Soil and foundation conditions
Soil and geologic conditions can vary significantly from one property to another.
Expansive soils and expansive bedrock occur in Colorado, and Colorado Geological Survey mapping identifies specific geologic hazards within portions of the Colorado Springs area. That does not mean every Colorado Springs property has problematic soil. Site conditions need to be evaluated individually.
When subsurface conditions matter, a geotechnical engineer evaluates the soil, bedrock, groundwater, and related conditions and provides geotechnical recommendations. The structural engineer then uses appropriate project and site information to design the foundation and structural system.
This is why foundation design should be based on the actual project rather than assumptions about what worked elsewhere in the neighborhood.
Sloped sites and retaining conditions
Some Colorado Springs properties include substantial grade changes. Where those conditions exist, they can influence foundation elevations, retaining walls, drainage relationships, and the structural layout.
Slope also matters when evaluating retaining-wall requirements. A relatively short wall with challenging loading or slope conditions may require more engineering attention than a taller wall on a straightforward site.
Snow, wind, and other structural loads
Structural design also accounts for the loads applicable to the building and location, including gravity, snow, wind, and other code-required loading conditions.
That is one reason a standardized framing detail or online house plan should not automatically be assumed to work for a specific Colorado Springs site. The building configuration, structural spans, loads, materials, and local requirements all matter.
Do you need an engineer, architect, contractor, or home inspector?
The right professional depends on the question you need answered.
Structural engineer: Contact a structural engineer when the issue involves structural capacity, foundations, beams, columns, framing, structural damage, load paths, or engineered structural plans.
Architect: An architect generally focuses on space planning, building layout, elevations, architectural design, design documentation, and coordination. Additions, custom homes, and other substantial residential projects often require architecture and engineering to work together.
Contractor: A contractor is responsible for executing the work in the field, including labor, construction methods, materials, pricing, scheduling, and coordination of construction. A contractor’s experience is valuable, but it does not replace engineering judgment where engineered design is needed.
Home inspector: A general home inspector evaluates a property broadly and may identify structural symptoms or conditions worth investigating. A structural engineer can then perform a more focused evaluation when necessary.
For projects requiring multiple technical disciplines, we can coordinate architecture, structural engineering, foundation design, and MEP under one roof. This approach gives homeowners, builders, and general contractors one coordinated technical team rather than requiring them to manage several disconnected scopes.
What does a structural engineer actually do for your project?
A structural engineer determines how the building’s structural components should safely support and transfer the loads placed on them.
Depending on the project, the work may include reviewing existing conditions, calculating loads, sizing beams and posts, designing framing or foundations, developing structural connections and details, preparing engineered structural plans, coordinating with architectural drawings, or answering permitting and construction questions within the agreed scope.
The deliverable depends on what the project actually requires. A structural evaluation may result in recommendations, while a new custom home may require a much more extensive engineered plan set.
Good structural engineering should provide clear, realistic information that supports permitting and gives the contractor something practical to build from.
When should you involve a structural engineer?
Ideally, involve the structural engineer before the project design is finalized or construction begins whenever the work will alter structural components.
Early coordination can identify constraints before major design decisions are locked in, reduce redesign, improve coordination between disciplines, and give the contractor clearer information before work begins.
For a homeowner planning a large kitchen opening, that may mean determining whether the wall is load-bearing and understanding the required beam and post configuration before cabinets, ceiling details, and floor plans are finalized.
For a builder developing a custom home, it may mean coordinating the foundation and structural framing while the architectural plans are still developing rather than waiting until the permit set is almost complete.
What should you have ready before contacting a structural engineer?
You do not need every technical detail figured out before reaching out. A good engineering partner should help clarify what information and services the project actually needs.
Helpful information includes:
- Property address
- A plain-English description of the project or concern
- Photos of relevant existing conditions
- Architectural plans or sketches, if available
- Existing building plans, if available
- A home inspection report, when applicable
- Known geotechnical information, when applicable
- Approximate project timeline
- Contractor or architect contact information when coordination is needed
For structural concerns, it can also help to explain when you first noticed the condition and whether it appears to be changing.
What happens after you contact a structural engineer?
The process should begin by defining the problem before deciding what engineering work is appropriate.
1. Discuss the project
We start with the property, project type, proposed work, or structural concern so we can understand why engineering may be needed.
2. Review the available information
Depending on the project, that can include photographs, architectural plans, sketches, inspection reports, existing drawings, or geotechnical information.
3. Determine whether additional information is needed
Some projects require a site visit or additional investigation. Others can proceed from complete plans and project information without an inspection.
4. Define the engineering scope
The next step is establishing what structural services and deliverables are actually required.
5. Complete the design or evaluation
The agreed scope may produce structural calculations, recommendations, details, foundation plans, framing plans, or other engineering documents.
6. Coordinate toward permitting and construction
Where applicable, the engineering becomes part of the broader project package, supporting permitting and giving the builder practical, construction-ready information.
When should you call a structural engineer right away?
Prompt professional evaluation is appropriate when you observe sudden or significant structural movement, major new cracking, visible displacement of structural components, substantial sagging, or serious damage following fire, impact, severe weather, or another event.
The same applies when a contractor, inspector, or other qualified professional believes a structural condition may be unsafe.
Symptoms alone should not be used to diagnose the cause. If you reasonably believe part of a building may be structurally unsafe, do not enter or remain in the affected area while waiting for an evaluation.
How to choose a structural engineer in Colorado Springs
When searching for a structural engineer near you, look beyond whether the firm can simply produce a stamped drawing. The engineer should be a good fit for the particular building, project type, and construction team.
Consider:
- Colorado professional licensure appropriate to the work
- Experience with your type of residential project
- Familiarity with local permitting requirements
- Clear communication and responsiveness
- Practical, construction-ready structural details
- Ability to coordinate with architects, contractors, geotechnical engineers, and other disciplines
- A clearly defined scope and set of deliverables
For builders and general contractors, responsiveness and coordination are especially important. Structural decisions often affect architectural, foundation, mechanical, electrical, plumbing, and field-construction decisions, so delays or gaps between consultants can affect more than one part of the project. Our integrated approach is built around reducing those handoffs and providing practical, build-ready design and engineering support.

Frequently asked questions
Do I need a structural engineer for a home addition in Colorado Springs?
Often. Additions commonly require structural engineering when they involve new foundations, structural framing, roof changes, or large openings in existing walls. The exact engineering and permitting requirements depend on the project design and existing building.
Do I need a structural engineer to remove a wall?
If the wall is load-bearing or its structural role is uncertain, a structural engineer should evaluate the proposed change. The engineer can determine how the existing loads need to be supported through beams, posts, connections, and supporting structural elements.
Does a retaining wall need a structural engineer in Colorado Springs?
It depends on the wall height, slope, surcharge, soil conditions, and applicable permitting requirements. PPRBD currently identifies certain retaining walls not more than four feet high as permit-exempt, but important exceptions apply. The actual site conditions should be reviewed rather than treating height alone as the deciding factor.
Should I call a structural engineer for foundation cracks?
Contacting a structural engineer is appropriate when cracks are significant, changing, associated with visible movement, or accompanied by symptoms such as uneven floors, sticking doors, separation of building components, or foundation displacement. Minor cracking does not automatically indicate foundation failure.
Do I need an engineer for a deck in Colorado Springs?
Sometimes. Deck engineering depends on the configuration, spans, attachment, footings, loads, elevation, and applicable permitting requirements. PPRBD maintains specific residential deck plan-review requirements, so the appropriate documentation should be confirmed for your project.
Can you handle both architectural and structural plans?
Yes. We provide architecture, structural engineering, foundation design, and MEP services, allowing residential projects that require multiple technical disciplines to be coordinated through one team.
Get clear on what your project needs
Knowing when you need a structural engineer in Colorado Springs comes down to the work being proposed, how the building carries loads, the condition of the existing structure, site-specific factors, and applicable permitting requirements.
If you are planning a custom home, addition, ADU, deck, structural remodel, or foundation project, involving a structural engineer early can identify constraints before they become expensive redesigns or field problems.
