Springfield ADU / Accessory Dwelling Rules
Some RestrictionsADU Permits
Springfield permits accessory dwelling units in single-family residential districts under the Land Development Code (Code of Ordinances Chapter 36), with the City Council's adoption of an updated Community Land Development Code expanding ADU flexibility in conjunction with the Forward SGF 2040 comprehensive plan. ADUs are reviewed under accessory-use provisions and the district regulations in Chapter 36 Article III Division 4. Missouri has no statewide ADU enabling statute — under Dillon's Rule and RSMo Chapter 89 (Zoning), zoning authority rests with the municipality.

Some RestrictionsADU Impact Fees
Missouri does not authorize traditional municipal impact fees the way California or Washington do. RSMo Chapter 89 (Zoning) and Chapter 67 (Political Subdivisions) do not include a general development-impact-fee enabling statute, and Missouri courts have struck down fees lacking a specific statutory basis. Springfield charges building permit fees calculated on construction valuation under the adopted International Residential Code and City Utilities water/sewer tap fees, but no separate parks, transportation, or school impact fees on ADU construction.

Few RestrictionsADU Owner Occupancy
Springfield's Community Land Development Code conditions ADU approvals in single-family districts on owner-occupancy of either the principal dwelling or the accessory unit, consistent with the design and operation conditions adopted with the Forward SGF 2040 implementation. The owner-occupancy expectation is part of how the City balances ADU flexibility against neighborhood concerns near Missouri State University and in established single-family neighborhoods. Missouri has no statewide preemption of municipal owner-occupancy rules — unlike California AB 671 or Washington HB 1337, no Missouri statute prohibits this requirement.

Some RestrictionsADU Rental Restrictions
Long-term rentals of accessory dwelling units in Springfield must comply with the Rental Inspection Program administered by Building Development Services, which requires annual registration and exterior code inspection of every non-owner-occupied dwelling unit. Short-term rentals (less than 30 days) are separately regulated under Code Section 36-473, which establishes three tiers (Type 1 owner-occupied, Type 2 non-owner-occupied in R-SF/R-TH, Type 3 non-owner-occupied in multi-family districts) each with distinct application fees, zoning restrictions, and density buffers. Missouri prohibits municipal rent control under RSMo Section 441.043.
