Summary
In Tuscaloosa's D, DHE and DP zoning districts, an accessory dwelling unit is only legal if the owner of the lot lives in the principal dwelling as a legal and permanent residence. Sec. 25-107(a)(4) lets the city verify that through voter or vehicle registration.
4.In the D, DHE, and DP districts, the principal dwelling unit shall be used by the owner of the lot as a legal and permanent residence. For purposes of this paragraph, the owner's legal and permanent residence shall be evidenced by voter registration, vehicle registration, or in a similar way.

Full Breakdown
Sec. 25-107(a)(4) singles out the D, DHE, and DP districts, downtown and downtown-adjacent zones where ADUs are also permitted by right under Table V-5, and imposes an owner-occupancy condition that does not apply to the other districts where ADUs are allowed, such as CN, SFR-4, SFR-5, MR-1 or MR-2. " In practice, this means an investor who buys a house in the D, DHE or DP district cannot add an ADU and rent out or leave vacant the main house while someone else occupies the ADU; the lot owner has to actually live in the principal home and be able to document that residency with public records such as their voter or vehicle registration address.
The requirement sits alongside the two rental restrictions in Sec. 25-107(a)(2)-(3), which separately bar using the ADU itself as a short-term rental and bar the owner from living in the ADU while renting out the principal house as a short-term rental, so together the district-specific owner-occupancy rule and the rental bans are meant to keep these downtown accessory units tied to actual, verifiable residents rather than investment or vacation-rental inventory. The standard was adopted with the Unified Development Ordinance rewrite, Ord. No. 9572, Sec. 2, effective December 17, 2024.
Violations & Fines
Sec. 25-107(a) does not set its own fine for a violation of the owner-occupancy condition; it is enforced as a zoning code violation under the citywide general penalty in Sec. 1-8, up to a $500 fine plus up to six months of confinement or hard labor at the court's discretion, with each day of noncompliance a separate offense. A lot owner disputing a finding that they no longer occupy the principal dwelling can appeal to the zoning board of adjustment under Sec. 25-45, which reverses only on a showing of clear and demonstrable error in the record.
