Our Home Base

Home additions for Highlands Ranch homes

Space isn’t usually the constraint in Highlands Ranch — the lots are conventional suburban and the homes are sound, so building out is realistic. The constraint is the approval stack. An addition is exterior by definition, so it goes to HRCA’s Architectural Review Committee under the Residential Improvement Guidelines, and the Community Declaration plus your neighborhood’s Supplemental Declaration set the standards your design has to meet.

Then the Metro District reviews water and sewer impacts, and its approval is required before Douglas County will issue the building permit or a certificate of occupancy. Structurally, a second-story addition still needs an engineer to confirm your foundation and framing can carry it, with plans stamped by a Colorado-licensed engineer — Highlands Ranch’s newer construction usually gives us more to work with, but it’s never assumed.

What We Build

Permits and approvals in Highlands Ranch

Home additions at this scope is permitted work, and we pull the permits and schedule the inspections for you. In Highlands Ranch that runs through the Douglas County Building Division, via the county’s permitting system, under the International Residential Code as adopted by Douglas County.

Highlands Ranch has the most layered approval process in our entire service area, and it catches nearly everyone. It isn’t a city — it’s an unincorporated community in Douglas County, so the county’s Building Division is the authority having jurisdiction, not a city hall. On top of that, the Highlands Ranch Metro District reviews projects on behalf of Highlands Ranch Water for impacts to the public water and sewer systems, and Metro District approval is required before Douglas County will issue a building permit or a certificate of occupancy. That’s two approvals before you break ground.

You can be fully permitted by Douglas County and still be in violation with HRCA. Three approvals, in the right order, is how a Highlands Ranch project stays out of trouble.

We build additions across Highlands Ranch, including Northridge, Southridge, Eastridge, Westridge, Backcountry, Highwoods, Timberline Ridge, and Shadow Canyon, and the surrounding neighborhoods.

Highlands Ranch Questions

Home additions FAQs — Highlands Ranch

Q.01
What's the approval process for an addition here?

An addition is exterior, so HRCA’s ARC reviews it under the Residential Improvement Guidelines, your neighborhood’s Supplemental Declaration sets the standards, the Metro District reviews utility impacts, and Douglas County issues the permit — but only after the Metro District signs off.

Q.02
Can I be permitted and still be in violation?

Yes, and it happens. Full Douglas County permitting doesn’t satisfy HRCA. The two are separate and both are required — which is exactly why we sequence them.

Q.03
Can my home support a second story?

Often, but never assumed. We have a structural engineer evaluate your foundation and framing before design, with plans stamped by a Colorado-licensed engineer.

Q.04
How long does a Highlands Ranch addition project take?
Additions run from a few months to the better part of a year, and permitting adds weeks to months before construction starts. You get a schedule in your proposal. For a fuller breakdown of home addition costs, see our cost guide.
