What a pop-top covers
A pop-top in the Denver metro raises or replaces the roof on the existing footprint to add a story or habitable attic. Walls usually stay; massing and bulk plane control the envelope. The existing foundation still has to take the new loads. A municipally licensed Denver general contractor coordinates the project, design professionals, and licensed specialty trades. Cost is project-specific and depends on roof structure, stairs, and how much of the first floor is opened.
text
Bulk plane, height, and landmarks
Zoning height is measured in feet and stories from the front and rear base planes (DZC Sec. 13.1.2). Plans must show allowed versus proposed bulk plane, including roof overhangs. If the existing house already breaks height or bulk rules, elevations should distinguish retained structure from new work. Landmark Preservation lists pop-top/rooftop additions as a review type; designated properties need Landmark approval before zoning or building permits.
text
Permits and who coordinates the work
City and County of Denver Community Planning and Development treats pop-tops like other second-story or attic work: structural review and a sealed structural-integrity letter from a design professional who inspected the existing foundation (DBCA 133.3), plus zoning, building, and typically SUDP. Cities and counties license general contractors. Colorado has no statewide general contractor license. Autotelic acts as a municipally licensed Denver general contractor and coordinates licensed specialty trades plus the design professionals required for the project.
text
What buyers should prepare
Target rooms, roof and attic photos, known foundation issues, and landmark or historic-district status.
FAQ
Common questions
Is a pop-top different from a second-story addition?
A pop-top usually stays on the existing footprint and is controlled by bulk plane. A second-story addition may also expand walls. Both need structural review in Denver.
Who handles pop-top permits and licensing?
A municipally licensed Denver general contractor coordinates the project, design professionals, and specialty trades. Colorado has no statewide general contractor license.
Do historic houses need extra review?
Yes. Landmark lists pop-top/rooftop additions. Approval comes before zoning and building permits on designated properties.
Will the existing foundation work?
Only after a design professional inspects it. CPD asks for a sealed structural-integrity letter for second-story and attic work.
What information helps define scope?
Desired rooms, roof photos, landmark status, and city or county.
