Colorado Springs vs. Pueblo ADU rules
Colorado Springs and Pueblo both finished ADU compliance in 2025, but Pueblo started from a near-total ban — new ADUs were prohibited citywide until Ordinance 11022 took effect August 25, 2025, while Colorado Springs (Ordinance 25-45) simply rewrote existing rules, tightening as much as it loosened. Colorado Springs caps a detached ADU at 16 ft, the strictest height limit in the region, and requires one off-street parking space per unit — council restored that mandate over staff's objection. Pueblo needs new parking only in the statute's narrow three-condition case, but demands the heaviest design menu around: at least 7 of 17 listed exterior features under PMC 17-4-16(c).

Colorado Springs: worth knowing
- An ADU and a short-term rental can't coexist on the same property (grandfathered only if both were legal by June 30, 2025).
- The 16-ft detached height cap is the region's strictest — it effectively rules out two-story DADUs except over converted garages.
- A detached ADU meeting all subdivision provisions may be subdivided and sold — otherwise a recorded no-separate-sale covenant applies.
- Prefab and tiny homes qualify on permanent foundations; the ordinance created a new ADU-O overlay district.
- The ordinance's recitals stake an explicit home-rule position against conflicting state law — making Colorado Springs a jurisdiction to watch if ADU preemption ever reaches the courts.
Colorado Springs: on our watchlist
The city's supportive-jurisdiction certification status is unverified; its home-rule recitals make it a candidate for future preemption disputes over the parking and height provisions.
Pueblo: worth knowing
- The distinctive Pueblo requirement: a detached ADU must be color- and material-complementary to the house AND incorporate at least 7 of 17 listed design features — the heaviest design menu in our corpus.
- No separate sale or subdivision of the ADU from the residence.
- Manufactured homes qualify as ADUs on an engineered permanent foundation; mobile homes and RVs don't.
- The legacy pre-1968 'established ADU' category survives as its own classification.
- Between the state deadline (June 30, 2025) and adoption, Pueblo operated under a state-granted extension — a nuance most coverage misses.
