SF 592: A bill for an act relating to county and city regulation of accessory dwelling units.

This bill mandates that counties and cities in Iowa must allow at least one accessory dwelling unit (ADU) on lots with single-family residences. It directly affects property owners by standardizing and simplifying the process of building ADUs, and local governments by limiting their regulatory authority. The legislation sets statewide parameters, such as allowing ADUs up to 1,000 square feet or 50% of the main house, whichever is larger. It prohibits local ordinances from imposing overly restrictive rules on aspects like design, parking, owner-occupancy, or separate utility connections. Furthermore, it requires local governments to approve compliant ADU permits without discretionary review, following the same timeline as single-family home permits.

HF 2618: A bill for an act eliminating the Iowa smart planning principles and other local comprehensive planning and development guidelines.

HF 2618 repeals Iowa's "smart planning principles" (sections 18B.1 and 18B.2), which required local governments and state agencies to consider 10 specific guidelines in planning, zoning, and development decisions. The bill removes these requirements from state code, eliminating the obligation for cities, counties, and state agencies to reference or apply these principles when creating comprehensive plans, zoning regulations, or infrastructure projects. It also deletes related references from other sections of Iowa law governing regional planning (28I.4), airport zoning (329.3), and local development regulations (335.5, 414.3). This change directly affects how local governments approach land use and development planning across Iowa.

SSB 3152: A bill for an act relating to county zoning ordinances governing residential buildings.

This bill (SSB 3152) limits county zoning authority over residential construction in unincorporated areas. It prohibits county boards from restricting the construction or development of residential buildings, except for regulations necessary for safety (e.g., fire codes or structural integrity). The law defines "residential building" to include single-family homes, townhouses, and small apartment buildings (up to 12 units per building), but does not allow counties to impose rules that would hinder housing development. This change directly affects county boards of supervisors and developers working outside city limits in Iowa.

SF 2442: A bill for an act relating to county zoning ordinances governing residential buildings.

This bill (SF 2442) limits county zoning boards' authority over residential construction in unincorporated areas. It prohibits counties from restricting the building or development of residential properties - defined as single-family homes, townhouses, and small apartment buildings (up to 12 units per building) - except for regulations necessary to protect life or property safety. Counties may no longer impose rules on residential construction for non-safety reasons, such as limiting building density or lot coverage. The law directly affects homeowners, developers, and county zoning boards in rural and unincorporated regions of Iowa. It updates existing zoning authority to prioritize construction access while maintaining safety-based regulations.

HF 2659: A bill for an act establishing an affordable housing task force.

HF 2659 creates an Iowa affordable housing task force to study how state and local regulations impact housing costs. The task force will examine zoning, building codes, permitting processes, and funding mechanisms affecting affordable housing development, specifically looking at whether regulations provide public benefits proportional to their cost impact. It requires a diverse membership including state agency representatives, housing developers, local officials from cities and counties of varying sizes, housing nonprofits, and legislative members. The task force must submit a report with recommendations to reduce regulatory barriers by December 1, 2026, while maintaining public health and safety standards.

HF 2386: A bill for an act related to city regulation of single-family residential property.

HF 2386 allows Iowa cities to require the first buyer of a single-family home in a new housing development to live in the home as their primary residence for one year after purchase. Cities may impose fines of up to 25% of the home’s fair market value for violations, but must include a good-faith sale exemption if the owner needs to sell during the occupancy period. The bill defines "new housing development" as homes sold for the first time, including newly built properties under city-developer agreements, and specifies "occupy" means physically living in the home as a residence. This bill directly affects first-time homebuyers in new developments and gives cities a regulatory tool to address potential investor speculation.

SF 2378: A bill for an act relating to the ability of property owners to protest proposed changes in zoning districts.

SF 2378 removes a requirement that allowed property owners to block zoning changes by submitting written protests. Specifically, it repeals a provision (Code 414.5) that let owners with 20% of affected property area or 20% of property within 200 feet file protests to stop zoning district changes unless approved by a 3/4 city council vote. The bill directly affects property owners who previously could use this written protest process to challenge zoning amendments. It eliminates the need for cities to seek 3/4 council approval when such protests are filed, streamlining the approval process for zoning changes. The change applies to all zoning district modifications, not just specific uses like shooting ranges.

SF 2369: A bill for an act relating to county and city regulation of accessory dwelling units.

This bill requires Iowa counties and cities to allow at least one accessory dwelling unit (ADU), or secondary home, on the same lot as a single-family residence in areas where single-family homes are permitted. It sets clear size limits: ADUs cannot exceed 1,000 square feet or 50% of the main home’s size (excluding unfinished basements), and defines "size" to exclude garages and decks. The bill also restricts local governments from banning ADUs solely due to historic preservation rules - ADUs in historic districts can only be limited if a commission documents they clash with the area’s historical character. This directly affects homeowners in single-family zones seeking to build or rent out secondary living spaces.

HF 2636: A bill for an act relating to the ability of property owners to protest proposed changes in zoning districts.

This bill (HF 2636) changes Iowa's zoning rules to make it harder for cities to change land use districts. It requires property owners within 200 feet of a proposed change to collectively sign a written protest representing 20% of the affected property's area before a public hearing. If such a protest is filed, the city council must then vote by a two-thirds majority (instead of three-fourths) to approve the zoning change. The bill directly affects nearby property owners who can block changes and city councils that must follow the new voting threshold. It aims to give more local property owners influence over zoning decisions.
