Lone Tree additions, remodels and bathroom renovations.
Design-build across Lone Tree — additions, whole-home remodels, bathrooms, kitchens and structural work, designed to the Planned Development your address actually sits in.
In Lone Tree, your setbacks are not in the municipal code. They are in your PD plan.
Lone Tree is largely Planned Development, and the code explicitly lets a PD modify almost any standard in the zoning chapter. The city publishes seventeen separate Planned Development documents — RidgeGate, Heritage Hills, Park Meadows, Carriage Club, Meridian, Lone Tree Town Center, Westbrook, Willow Creek and others. For most Lone Tree addresses the setbacks and height that govern your project come out of that document, not out of Chapter 16.
Verified against official City of Lone Tree and Colorado Department of Local Affairs sources as of August 2026. Code editions and ADU rules change, and several Front Range jurisdictions are mid-revision right now. Treat this as the starting point for your project, not as legal advice, and confirm the current standard with the Lone Tree Building Division on 720-390-5211 before you commit to a design. We do that on every job as a matter of course.

Lone Tree questions we get asked.
What are the setbacks on my Lone Tree lot?
That depends which Planned Development you are in, and for most Lone Tree addresses the answer is not in the municipal code. Section 16-2-170 lets a PD modify almost any standard in the zoning chapter, and the city publishes 17 separate PD documents including RidgeGate, Heritage Hills, Park Meadows, Carriage Club, Meridian, Lone Tree Town Center, Westbrook and Willow Creek. Identifying and reading the governing PD is the first step on any Lone Tree project. RidgeGate stacks further still – the 7th Amendment PD District plus the East Villages and City Center sub-area plans on top of the comprehensive plan.
How tall can a detached garage or studio be in Lone Tree?
Ten feet by right, and 20 feet only with Community Development Director approval, under Section 16-7-110(a)(2). That is unusually tight and it is the rule that most often reshapes a detached accessory building here. Principal buildings in the SR districts are capped at 35 feet. Note that your PD may modify these, which is why we read it first.
How long does a Lone Tree building permit take?
Lone Tree does not publish building permit review times, and we will not invent one. You may find a five-working-day figure on the city site – that applies to Public Works permits only, and applying it to a building permit would be a false promise. What is published is the fee structure: plan review at 65 per cent of the permit fee with a $100 minimum, and additional review caused by changes at $100 per hour with a two-hour minimum. Submittal is electronic through Accela.
