What buyers should know

Confirm whether the property sits over the Edwards Aquifer recharge, contributing, or transition zone — each carries different development and impervious-cover rules set by SAWS and the city.

If buying in an older central neighborhood (King William, Monte Vista, Tobin Hill, and others), check whether the property is in a local historic district subject to HDRC review before any exterior changes.

Military buyers relocating to JBSA should verify homestead exemption timing and escrow assumptions after the move, since Texas residency requirements affect when the exemption kicks in.
