ADU rules in Austin suburbs - Leander, Cedar Park etc.

[Madhu G.]

Hey folks, 

Can you pls share what you know about zoning laws in Austin suburbs? I see this page that talks about ADU laws being relaxed in Austin in 2015. https://www.austintexas.gov/pa...

1. Does this rule apply to suburbs (Leander, Cedar park, Round Rock etc.) as well?

2. If I am looking to buy a house with plans to add an ADU, what is the diligence I need to do (before buying the home) in addition to city zoning laws ? I can think of HOA rules. Anything else to keep in mind?

Thank you!
