HF 2252: A bill for an act relating to county and city regulation of accessory dwelling units.

HF 2252 requires Iowa counties and cities to allow at least one accessory dwelling unit (ADU), like a backyard cottage or basement apartment, on single-family residential lots where such homes are permitted. The bill sets size limits (max 1,000 square feet or 50% of the main house, excluding unfinished basements) and prohibits local governments from imposing stricter rules on ADUs in communities with shared ownership (like condos) than on standard single-family homes. It also modifies historic district regulations, requiring preservation commissions to formally justify any ADU restrictions based on historical significance. This directly affects homeowners seeking to build ADUs, local zoning authorities, and historic preservation boards.

SSB 3070: 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) - a secondary home on the same lot as a primary residence - in zoning districts where single-family homes are permitted. It sets size limits (max 1,000 sq ft or 50% of the main house size, excluding unfinished basements, garages, decks, and unheated porches) and restricts local governments from banning ADUs solely due to historic preservation rules unless a commission documents specific historical incompatibility. Homeowners seeking to build ADUs and local governments creating zoning rules are directly affected. The bill clarifies that historic district restrictions must be justified by a commission’s written determination, replacing prior broad exemptions.

SF 2091: A bill for an act relating to the ability of property owners to protest proposed changes in zoning districts.

This bill repeals a provision (Code section 414.5) that allowed property owners to submit written protests against proposed zoning district changes. Specifically, it removes the requirement that city councils must obtain a 3/4 vote to approve zoning changes if 20% of affected property owners file a written protest before a public hearing. The bill directly affects property owners who previously could challenge zoning changes through this protest mechanism. It eliminates this specific procedural step, meaning zoning changes would no longer require the 3/4 council vote if a protest is filed. The bill does not change other zoning approval processes, such as the requirement for shooting range modifications.

HF 2148: A bill for an act eliminating the Iowa smart planning principles and other local comprehensive planning and development guidelines.

HF 2148 eliminates Iowa's "smart planning principles" by repealing Chapter 18B of the Iowa Code, which previously required local governments to consider 10 specific planning guidelines in their comprehensive plans and zoning decisions. This bill directly affects cities and counties across Iowa, removing a mandatory requirement to incorporate these principles when developing or updating land-use plans, zoning regulations, or infrastructure projects. Key provisions include deleting references to the smart planning principles from multiple sections of Iowa law and repealing the foundational sections (18B.1 and 18B.2) that mandated their use. As a result, local governments will no longer need to formally consider these specific principles during planning processes, shifting planning authority to local discretion without state-mandated guidelines.

HF 2062: A bill for an act relating to the ability of property owners to protest proposed changes in zoning districts.

HF 2062 repeals a provision that allowed property owners to challenge proposed zoning changes by filing a written protest signed by owners of 20% of the affected area or within 200 feet of the property. Currently, such a protest would require a city council to approve the change with a 3/4 majority vote. This bill removes that requirement, meaning zoning changes would no longer need the higher vote threshold if a protest is filed. The change directly affects property owners in areas where zoning district modifications are proposed, eliminating their ability to block such changes through this specific process.

HSB 618: 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) on a lot with a single-family home in permitted zoning areas. ADUs must not exceed 1,000 square feet or 50% of the main house's size (whichever is larger), excluding unfinished basements, and cannot face stricter rules in common interest communities than for single-family homes. Local governments may only restrict ADUs in historic districts if a commission determines they conflict with the area's historical character and records the justification. Additionally, manufactured homes used as ADUs must be placed on a permanent foundation and taxed as real property.

SSB 1180: A bill for an act relating to the assessment of certain development property, and including effective date and retroactive applicability provisions.

This bill maintains the pre-development property tax assessment for land used in housing or commercial development starting January 1, 2020, or later. It prevents local assessors from changing a lot's tax classification until the property is improved with permanent construction, sold, or five years pass after the subdivision plat is recorded - whichever happens first. The rule applies to all development activities, including zoning changes, clearing lots, or installing utilities, but excludes special assessments. It takes effect immediately and applies retroactively to tax assessments beginning January 1, 2025.

SSB 1182: A bill for an act relating to county and city regulation of accessory dwelling units.

Iowa's SSB 1182 requires counties and cities to allow at least one accessory dwelling unit (ADU) on single-family residential lots, with specific limitations on local restrictions. It prohibits municipalities from imposing stricter rules on ADUs than on main homes (e.g., size, appearance, parking, or rental use) and bans restrictions based on occupancy relationships, income, or age. The bill mandates that ADU permit applications be approved within 30 days without discretionary review, unless denied in writing with specific reasons. It directly affects homeowners seeking to add secondary housing units, such as in-law suites or rental cottages, by reducing local barriers to construction. The law applies to all counties and cities in Iowa, ensuring consistent rules for ADU development across the state.

SSB 1185: A bill for an act concerning county and city regulation of real property and the powers granted to a board of adjustment.

This bill clarifies rules for local governments (counties and cities) when granting zoning exceptions, called "variances," to property owners. It requires property owners seeking exceptions to prove two things: the hardship is unique to their specific property (not caused by their own actions) and the exception won’t change the character of the neighborhood. The bill specifies that variances can apply to common zoning rules like lot size, building height, setbacks, parking, and signage. Local boards of adjustment must ensure exceptions align with public interest and zoning goals before approving them. This directly affects property owners facing strict zoning rules and the local boards that review their requests.

HF 415: A bill for an act concerning county and city regulation of real property and the powers granted to a board of adjustment.

HF 415 clarifies how county and city boards of adjustment can grant variances from zoning rules for property owners. It requires property owners seeking exceptions to prove the difficulties are unique to their specific property (not self-created) and that the variance won’t significantly change the neighborhood’s character. The bill specifically covers variances for requirements like minimum lot size, setbacks, parking, signage, and building height. It does not change zoning rules but sets clearer standards for when boards may approve exceptions to allow beneficial property use.
