Summary
Allen County's Zoning Ordinance has no separate tiny-home category. A dwelling must meet its district's minimum standards. Temporary structures such as portable storage containers are capped at 90 days (120 with a Certificate of Use) and cannot be used as permanent housing.
A temporary storage or similar structure, including a portable storage container, shall be permitted in a residential district for up to 90 days without a Certificate of Use; if the applicant obtains a Certificate of Use then the structure may be permitted up to 120 days.
Full Breakdown
The Allen County Zoning Ordinance regulates dwellings by district minimum standards, not by a tiny-home label. A permanent small house must satisfy the applicable district's building-size and setback rules and Indiana building code, and a compact second unit is treated as an accessory dwelling unit (one per lot; an integrated ADU must be at least 300 square feet). A tiny house on wheels or a portable structure is a temporary accessory structure: in a residential district a temporary storage or portable container is allowed up to 90 days without a Certificate of Use, or up to 120 days with one, and cannot serve as a permanent residence.
Violations & Fines
Occupying a tiny house on wheels or a portable structure as a permanent dwelling, or exceeding the temporary-structure time limits, is a zoning violation subject to Planning Services enforcement and fines.
