Bill Summary · SB 673

Legislative bill overview

SB 673 grants Texas municipalities and counties the authority to regulate accessory dwelling units (ADUs) on residential properties and permits them to charge fees for ADU-related permits and inspections. The bill establishes a framework allowing local governments to set their own rules regarding ADU development while generating revenue through regulatory fees.

Why is this important

ADUs—small secondary dwellings on single-family residential lots—are increasingly viewed as a solution to housing affordability and supply challenges. This bill determines whether local governments can control ADU proliferation in their communities and how they fund related regulatory oversight, directly affecting housing density, neighborhood character, and local government budgets across Texas.

Potential points of contention

  • Local control vs. housing access: Empowering municipalities to regulate ADUs may allow some communities to restrict housing options through strict rules, potentially limiting the statewide housing supply benefit that advocates see in ADU legalization
  • Fee structure concerns: The authorization for regulatory fees could make ADU development cost-prohibitive in some jurisdictions if fees are set too high, undermining affordability goals while benefiting municipal budgets
  • Regulatory inconsistency: Allowing each municipality and county independent rulemaking authority creates a patchwork of regulations across Texas, complicating development for builders and potentially favoring certain regions over others
