Key legal question
Whether the electric house-door opener qualifies as a disability aid under the self-care category (Ziff. 14.04 HVI).
Extracted holding
No. Ziff. 14.04 HVI covers structural adaptations in the apartment, not measures at the house entrance; the requested device therefore falls outside that category.
Extracted reasoning
The list under Ziff. 14 HVI is exhaustive, and adaptations 'in the apartment' do not extend to the entrance door. The exchangeability argument did not alter this categorical limit.
