Texas HOA
Texas HOA Voting Rights & Use Rights Suspension Calculator
Determine whether a Texas HOA may suspend a delinquent owner's voting rights (operational matters) and common-area use rights under Tex. Prop. Code § 209.0051(c).

How these calculators stay honest
Every calculator names the statute, rule, or filing it implements and links the primary source. The math lives in a pure function with its own unit-test suite; both sit in the public-facing repo alongside the page that renders the result. A visible "last reviewed against" stamp updates when the underlying rule changes.
These are planning tools, not professional advice. They're free to use, ad-supported, and built to be verified rather than trusted on reputation.
