Summary
Oxnard's zoning code does not have a separate "tiny home" ordinance: Section 16-465.1(A) folds tiny homes into the definition of an accessory dwelling unit (ADU), so a backyard tiny house is built and permitted exactly like any other ADU, with the same size, height and permanent-foundation rules that apply citywide under Division 13 of the zoning code.
"Accessory dwelling unit" (ADU; also known as "second unit," "granny flat," "in-law suite," "tiny home" and/or "cottage") are small residential units on a permanent foundation located within, attached to, or detached and adjacent to the primary single-family unit or multi-family structure, and can provide an important source of affordable housing. An ADU shall include permanent provisions for living, sleeping, eating, cooking, and sanitation on the same parcel as the single-family or multi-family dwelling is or will be situated.

A detached tiny home with one bedroom or less tops out at 850 square feet of interior livable space, and one with more than one bedroom tops out at 1,200 square feet, while an attached unit is capped at 1,200 square feet or 50% of the primary home's floor area, whichever is less.
