ADU Impact Fees

Saint Paul does not charge general residential impact fees on ADUs because Minnesota Statutes §462.358 limits municipal impact-fee authority. Costs are limited to DSI building permit fees, plan review fees, sewer availability charges (SAC) from the Metropolitan Council, and Saint Paul Regional Water Services connection fees.

ADU Owner Occupancy

Saint Paul's 2016 ADU ordinance (Chapter 65 of the Legislative Code) historically required owner-occupancy of either the principal dwelling or the ADU. Minnesota HF 4029 (2024) effective January 1, 2025 prohibits cities from imposing owner-occupancy as a precondition to ADU approval, overriding any remaining local requirement. Both units must comply with Saint Paul Rental Licensing under Chapter 40 if rented to non-owners.
