Overlapping legend: How to put geopandas legend next to the map?

I am using geopandas and contextily to plot building data (polygon) from OpenStreetMap. The problem is, the legend is overlapping the map. Is there any way to put the legend next to the map? or plot the map without legend, but export the legend separately from the map?

I hope the image helps.

here’s my code to produce the map (I know the code is a little different, but it yields the same map):

from matplotlib import pyplot as plt
import geopandas as gpd
import contextily as ctx
%matplotlib inline

buildings = gpd.read_file("buildings.shp")
fig, ax = plt.subplots(1,1,figsize=(9,9))
buildings.to_crs(epsg=3857).plot(column='building', ax=ax, cmap="Paired", legend=True)
ctx.add_basemap(ax, url=ctx.providers.Esri.WorldTopoMap)
ax.axis('off')
plt.show()

buildings = gpd.read_file("buildings.shp")
fig, ax = plt.subplots(1,1,figsize=(9,9))
buildings.to_crs(epsg=3857).plot(column='building', ax=ax, cmap="Paired", legend=True, legend_kwds={'bbox_to_anchor': (1.3, 1)})
ctx.add_basemap(ax, url=ctx.providers.Esri.WorldTopoMap)
ax.axis('off')
plt.show()
