How big can a Loveland ADU be?

✓ Verified against code · August 20, 2026

900 sq ft of floor area, counting all floor planes but excluding attached garages. On a large lot there is a second limit — the ADU cannot exceed 50% of your principal dwelling's floor area, and total site coverage still has to meet the city's Scale Thresholds. A useful quirk: ADU floor area is excluded from the Building Coverage Ratio calculation on standard lots.

How current is this?

Loveland’s ADU rules run under UDC §18.04.07.01 (Accessory Dwelling Units) (Ordinance 6805 (building on Ord 6762 and Ord 6636)). Loveland is bound by HB24-1152 through the North Front Range MPO rather than DRCOG. It has gone further than the statute requires on both parking and owner-occupancy, and the state has certified it as an ADU Supportive Jurisdiction — the opposite designation from the non-compliance findings elsewhere on the Front Range. One date matters: the parking exemption below is recent, arriving only with Ordinance 6805 on January 20, 2026. Before that, Ordinance 6762 required a space unless the adjacent street was at least 28 ft wide with on-street parking allowed. We verified this answer against primary sources on August 20, 2026, and every change we catch is logged in the changelog.
