ADUs vs. short-term rentals in Irvington
Short-term rentals allowed with local rules for Village of Irvington. Local Law No. 7 of 2019 amended the Village Zoning Code to permit and regulate STRs; requires a permit ($250 initial/$150 renewal), limits rentals to 180 days/year, requires owner primary residency for at least 5 years, and mandates periodic building inspections. These are separate questions from whether you can build an ADU — a unit you're allowed to add isn't automatically one you're allowed to rent nightly, so check both.
