Frequently Asked Questions

Common questions about SB15

Q

What does Texas SB15 do?

Senate Bill 15 preempts municipal zoning authority in major Texas metropolitan areas, mandating that cities approve residential plats with lots as small as 3,000 square feet and widths as narrow as 30 feet. This legislation strictly applies to unplatted tracts of five acres or more, effectively unlocking high-density single-family development on raw land previously restricted by large-lot zoning. While this creates significant value for developers, it will require aggressive legal posturing to force municipal compliance.
