Can I build an ADU in Pueblo now?
✓ Verified against code · August 19, 2026
Yes — since August 25, 2025. Before that, new ADUs were prohibited citywide (only pre-1968 units were recognized), so anything you read dated earlier describes a ban that no longer exists. One ADU per lot, up to 800 sq ft, by administrative approval.

How current is this?
Pueblo’s ADU rules run under PMC 17-4-16 (Pueblo Municipal Code) (Ordinance 11022). Until August 25, 2025, new ADUs were prohibited in Pueblo entirely — only units 'established' before February 1968 were recognized. The city obtained a six-month compliance extension from the state, then adopted rules that track the statute nearly verbatim. Everything written about Pueblo ADUs before late August 2025 describes a ban. We verified this answer against primary sources on August 19, 2026, and every change we catch is logged in the changelog.
