Urban Development Requirements for Smaller Counties

This bill sets specific urban development and land use requirements for counties with fewer than 500,000 residents.

What This Bill Does

  • Gives the director of a county's land use agency power to approve or deny applications for dividing land into smaller parcels (subdivision), combining parcels (consolidation), or re-dividing existing subdivisions (resubdivision).
  • Requires counties to allow at least two small homes (accessory dwelling units) on all residentially zoned lots, under certain conditions.
  • Changes how school impact fees are calculated for new developments.
  • Prohibits private agreements that limit the number of accessory dwelling units in urban areas.

Who It Names or Affects

  • Counties with fewer than 500,000 residents
  • People applying to subdivide or consolidate land
  • Homeowners wanting to build small homes on their property

Terms To Know

Accessory Dwelling Unit (ADU)
A smaller home built on the same lot as a main house, often used for rental income or housing family members.
Subdivision
The process of dividing a large piece of land into smaller lots to sell or develop individually.

Limits and Unknowns

  • It is unclear how the bill will be enforced and what penalties might apply for non-compliance.
  • The exact impact on housing inventory and school funding remains uncertain.
