Hairline vs. structural — reading the crack
Most Brevard stucco cracks are hairlines from thermal cycling — the wall expands in afternoon sun, shrinks at night, and the finish eventually gives at the weak points. Stair-step cracks tracking the block joints, or wide cracks near corners and window heads, usually mean settlement. Both are repairable; they just need different depths of attention, and the walk-through sorts one from the other honestly.
