Accessory Dwelling Units (ADUs)—also called backyard cottages, in-law suites, or casitas—are on the rise here in El Paso County and across Colorado’s Front Range. As housing costs climb and families look for more flexible living arrangements, homeowners are asking:
“Can I build an ADU on my property—and how do I do it right?”

At Essential Pillar Architecture, we specialize in thoughtful, permit-ready ADU design in Colorado Springs and beyond, serving clients across the Front Range and mountain communities. Whether you’re just starting to explore the idea or already have a vision, here are 5 things you should know before you build:


1. Zoning: Can You Build an ADU on Your Lot?

Not all neighborhoods in El Paso County or the surrounding areas allow ADUs. Zoning rules vary by municipality and even by lot. Things like setbacks, parking, height, and lot coverage can all impact what’s possible.

Pro Tip: Before hiring a builder, consult a design professional familiar with local zoning—we help clients interpret the rules and avoid costly surprises.


2. Design with Purpose

ADUs serve many uses: guest suites, rental units, home offices, or multigenerational housing. The design should reflect your goals—and your long-term vision.

We offer custom ADU plans tailored to your specific needs and property conditions, with an eye for beauty, function, and flexibility.


3. Permits Matter—And So Do Vacation Rental Rules

Permitting is mandatory—and essential—for any legal ADU in Colorado Springs, Monument, or nearby towns. Cutting corners here can lead to major issues with financing, insurance, or resale.

But here’s another layer many homeowners miss:
If you’re planning to use your ADU as a vacation rental (Airbnb, VRBO, etc.), you’ll need to check local short-term rental regulations.

These rules vary widely by municipality.

  • Colorado Springs has strict limits on short-term rentals.

  • Unincorporated El Paso County is more flexible, but still requires registration.

  • Some areas prohibit vacation rentals entirely in residential zones.

At Essential Pillar, we help you think through not just how to build your ADU—but also how to use it legally and strategically.

We provide permit-ready ADU plans that align with both building codes and your long-term goals—whether that’s hosting family or creating income.


4. Budget Beyond Construction

Building an ADU involves more than materials and labor. Factor in design, permitting, utility upgrades, excavation, and more.

We guide you through the process with your budget in mind—so your project stays on track and within reach.


5. Plan for the Future

Maybe it’s a home office today—but what about five years from now? We help clients think ahead so their ADU can evolve: housing a relative, becoming a rental, or adding long-term value.

Our designs are built for flexibility, longevity, and peace of mind.
