Can I Build an ADU on My Lot in Colorado Springs?

If your property is inside Colorado Springs city limits and has a single-family detached house on it, the answer is almost certainly yes. Since Ordinance #25-45 took effect in 2025, one ADU is allowed by right on any such property, in every zone district, approved through an administrative process with no public hearing. You do not need special zoning, a variance, or your neighbors' agreement.

Three checks are worth doing before you get attached to the idea:

• The wildfire overlay. In the Wildland Urban Interface Overlay district (the WUI-O, along the city's western and forested edges), detached and attached ADUs are not allowed; only integrated ADUs, built inside the existing house, are permitted there. The Colorado Springs Fire Department's wildfire risk site shows whether a property is in the overlay.
• Your HOA. The city does not enforce or override HOA covenants, so a covenant restricting accessory buildings or rentals can still stop a project the city would approve. Read your covenants first; Colorado's state-law HOA override only applies in certified "ADU supportive" jurisdictions, which Colorado Springs currently is not. More on that in our state-law guide.
• The city line. Unincorporated El Paso County has different, more restrictive rules, and addresses in places like Security, Widefield, Falcon, and Black Forest are often outside city limits. The city's SpringsView map shows your zoning and jurisdiction; when in doubt, confirm with county planning.

Beyond those, the practical constraints are dimensional rather than permission-based: the unit must fit the size cap (up to 1,250 square feet or half your home's size; see the size rule), meet height and setback standards, stay out of the front yard, provide one off-street parking space, and match the main house's design character. Corner, side, and rear yards are all fair game. The full standards table is in our ordinance guide, and the approval sequence is in the permit walkthrough.

One more early check that costs nothing and can save five figures: ask Colorado Springs Utilities whether your ADU could share the main house's water and sewer service or would need its own connection. That determination happens formally during permit review, but the answer shapes the budget more than almost any design choice, as our cost guide shows with the actual fee schedules.
