Accessory Dwelling Unit Contractor in Colorado Springs, CO

The City of Colorado Springs updated its ADU ordinance to allow attached, detached, and basement ADUs in most residential zoning districts. Key rules include owner-occupancy of either the primary home or the ADU, a maximum unit size tied to the primary dwelling's square footage, rear or side setbacks based on the underlying zone, and one off-street parking space unless your lot is near frequent transit. We verify your zoning, setbacks, and utility capacity during the initial consultation before design begins.

ADU costs in Colorado Springs depend on unit type, size, and site conditions. A basement ADU conversion typically ranges from $60,000–$110,000, a garage conversion from $55,000–$95,000, an attached addition from $120,000–$175,000, and a detached ADU from $150,000–$280,000. We provide a detailed, itemized estimate after reviewing your property, goals, and local requirements.

An accessory dwelling unit (ADU) is a secondary residential unit on a single-family lot. ADUs can be detached structures, garage conversions, basement conversions, or attached additions. They are commonly used for rental income, multigenerational living, or guest housing.

ADU regulations vary by zoning district and municipality. Many areas of El Paso County now permit ADUs with specific size, setback, and utility requirements. We can help you assess whether your property qualifies during the consultation process.

ADU costs depend on type, size, and site conditions. A basement conversion is typically less expensive than a detached ADU. We provide detailed estimates after reviewing your property, goals, and local requirements.

In most cases, yes. Colorado Springs and El Paso County allow rental of permitted ADUs, but there may be owner-occupancy requirements depending on your zone. We recommend confirming rental rules with the municipality before starting the project.

A basement conversion ADU typically takes 3 to 5 months. A detached ADU may take 6 to 9 months depending on site work, permitting, and construction complexity. We provide a detailed project schedule after the design phase.

Yes. Attached and detached garage conversions are one of the most cost-effective ADU pathways in Colorado Springs because the foundation, walls, and roof structure already exist. A garage-to-ADU conversion still requires a full permit, insulation and thermal envelope upgrades, replacement of the vehicle door with a code-compliant wall system, egress-compliant windows, and interior plumbing, electrical, and HVAC work. We handle the full scope, from the pre-application meeting with City Planning through certificate of occupancy.

El Paso County and the City of Colorado Springs regulate ADUs separately. Inside city limits, Colorado Springs's updated ADU ordinance now permits attached, detached, and basement ADUs in most residential zones, with size caps typically tied to the primary home's square footage and setback rules based on the underlying zoning district. In unincorporated El Paso County, ADUs are allowed on many single-family parcels subject to acreage minimums, setback requirements, and septic or well capacity where applicable. We confirm your parcel's zoning, ADU eligibility, and any owner-occupancy or parking requirements at the initial consultation before design begins.

Yes. We remodel existing ADUs and legacy accessory units — refreshing kitchens and baths, upgrading insulation and windows for Colorado's climate, adding accessibility features, correcting code issues flagged during a sale, and converting informal in-law spaces into fully permitted ADUs. If you're not sure whether your existing unit is permitted or up to current code, we can pull permit history and advise on the path to bring it into compliance.
