After-the-Fact Permitting Engineering in Denver — FAQ

Common questions from Denver clients

Can unpermitted work in Denver be legalized with an engineer's report?

In many cases, yes. Colorado building departments commonly accept PE-stamped as-built drawings, structural calculations, and an engineer's evaluation of existing work as part of an after-the-fact permit. We inspect the work, document it, specify any needed upgrades, and prepare the engineering package. Final permit approval is always made by the local building official.

What types of unpermitted work do you document?

Room additions, garage and attic conversions, accessory dwelling units, decks, balconies, patio covers, carports, removed or altered load-bearing walls, retaining walls, and commercial tenant improvements.

Will you need to open walls or ceilings?

Not always. We start with a non-destructive inspection and only recommend limited openings when framing, connections, or footings cannot otherwise be verified.
