Two Iowa buildings can be identical in every physical respect and land in different property tax classes from 2027, because of how the ownership was papered. SF 2472 revives Iowa's multiresidential property class and, in doing so, narrows the residential class to parcels “containing two or fewer dwelling units.”¹

What the Act changes

Section 441.21(13)(b) is struck and replaced. For the assessment year beginning January 1, 2027, multiresidential property is assessed at the residential percentage plus three percent, not to exceed 100%. For assessment year 2028 and every year after, residential percentage plus six percent.

A new § 441.21(13)(0e) provides that for equalization purposes under §§ 441.47 through 441.49, multiresidential property is still considered residential property.

The residential class itself narrows. Section 441.21(14)(a), as amended, applies from valuations established on or after January 1, 2027 to property “containing two or fewer dwelling units.” Moved out into multiresidential: mobile home parks, manufactured home communities, land-leased communities, assisted living facilities, and “[a] parcel primarily used or intended for human habitation containing three or more separate dwelling units.”

The dividing line is the parcel, not the building

This is where two forms of Iowa common ownership part company, and the reason is statutory rather than architectural.

A condominium under chapter 499B is separately assessed. Section 499B.11 levies tax on “each apartment and its respective appurtenant fractional share or percentage of the land, general common elements and limited common elements.” Each unit is its own parcel with one dwelling unit on it.

A housing cooperative under chapter 499A is not. Section 499A.14 provides that “[t]he real estate shall be taxed in the name of the cooperative, and each member of the cooperative shall pay that member's proportionate share of the tax in accordance with the proration formula set forth in the bylaws, and each member occupying an apartment as a residence shall receive that member's proportionate homestead tax exemption and credit.” One parcel. However many dwelling units the building holds.

How certain is this reading?

Let us be exact, because the honest answer is not the same for every part of it.

Clear rule: the statutory text quoted above — the new percentages, the two-or-fewer-dwelling-units test, the separate assessment of condominium units under § 499B.11, the single-parcel taxation of cooperatives under § 499A.14. Those are what the enacted law says.

Reasoned inference: the conclusion that a three-or-more-unit Iowa housing cooperative therefore moves into multiresidential from assessment year 2027. That follows from reading the three provisions together, and we think it follows straightforwardly — but SF 2472 never mentions cooperatives, condominiums, associations or covenants anywhere in its seventy-five pages. No source states this comparison. It is our reading of enacted text, not a rule anyone has announced, and no assessor has yet applied it.
