Question

Can I restrict the search to a city’s streets when using the Google Places Autocomplete?

Answer 1

You can set the Autocomplete options to use geocode as the type, which will restrict the results that are returned to addresses:

var input = document.getElementById( 'searchTextField' );
var options = {
  bounds: yourBounds,
  types: ['geocode']
};

autocomplete = new google.maps.places.Autocomplete( input, options );

There is no way to restrict the results to just streets, but this will largely achieve what you want. If you set yourBounds correctly, maybe limited to the area of a city, it will get you as close as currently possible.

Update responding to the comment:

If you want to start by entering a city, you can bind the map’s bounds to the Autocompletes bounds, which will have the map set its viewport automatically when a city is selected in the Autocomplete:

var options = {
  bounds: yourBounds,
  types: ['(cities)']
};
autocomplete =
    new google.maps.places.Autocomplete( input, options );
// This will bind the map's bounds to the Autocomplete's bounds:
autocomplete.bindTo('bounds', map);

Then, you can update the Autocomplete‘s types, similar to the above, to have it return addresses:

autocomplete.setTypes( [ "geocode" ] );

From there, you can have a read of the Places Library API Docs.
