# minimumZ

The minimum zoom level for a tile overlay.

```
get minimumZ(): number | null;
set minimumZ(minimumZ: number | null);
```

## Discussion

By default, the minimum zoom level for a tile overlay is the same as the minimum zoom level for MapKit JS built-in tiles. MapKit JS requests the overlay tiles when the map is above or at this zoom level.

The default value is `null`.
