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
What buyers should prepare
Target rooms, roof and attic photos, known foundation issues, and landmark or historic-district status.
FAQ
Common questions
How much does Home Addition Feasibility Consultation cost in Brighton?
$300.
How do I book?
Press Book next to the job, pick a date and a morning (8–12) or afternoon (12–4) window, and pay in full. We confirm within 24 hours or refund you in full.
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.
What information helps define scope?
Desired rooms, roof photos, landmark status, and city or county.
