Planning Commission Meeting Minutes February 13, 2025 Page 4 of 8 Hirt said that their guess was around 10 newly built units per year from the best regional data available based on a study of the number of ADUs per single family units, but that this was not likely to be an accurate projection. Hirt addressed Baskett's earlier question about duplexes, and said that ADUs would only be allowed on lots with single family units, and not duplexes, under the proposed ordinance. Zuccaro said that the state law only applied to single family units, but noted that the Commission could recommend staff expand it to cover other housing types like duplexes and triplexes. Hunt asked for the reasoning on this. Zuccaro suggested that it would be a community character question, and that they might not want to add more density to areas that were already denser. Brauneis asked about an earlier proposed PUD that included garden level ADUs, and asked whether the proposed ordinance would allow for this. Zuccaro said no, but that the Commission could recommend that this be covered by the ordinance. Moline asked about staff's reasoning for the minimum size requirement for ADUs. Hirt said that there was no minimum square footage. He said that the state required them to allow at least a minimum of 500 square feet, but that staff are not proposing a minimum in the ordinance. Mihaly asked whether there would be any occupancy limits for ADUs. Hirt said no in the zoning code, because they were unable to do so under state law. Zuccaro said that the building code would set a minimum space per person. Bangs asked whether there would be an owner occupancy requirement. Hirt said the City couldn't do that under state law. He added that the City could require the owner occupy the main residence at the time the permit is issued for the ADU, but they could not require anything beyond that. Bangs asked to confirm that a current rental property could have an additional rental ADU added. Hirt said yes. Brauneis asked about the difference between an addition and an ADU. Hirt said that it would largely depend on how the space was used and noted that an attached ADU could come in and out of being defined as an ADU over time. Choi asked about the difference in impact fees for an addition versus the impact fees for an ADU. Zuccaro said that the impact fees were based on the square footage of the property, and that the expectation was that those would apply to whole property. Hunt asked whether these would apply differently to an ADU than to a building addition. Zuccaro said that it would not make a difference whether it was for an addition or for an ADU. Mihaly asked what would make something an ADU.
