Changing zoom for marker location?

I have one marker with my address and it is extremely zoomed in. How do I change the zoom level? Here is my code

$('#map_here').prepend('<div id="map"></div>');
        $(".static_map").remove();

        var map;
        var bounds;
        var geocoder;
        var center;

        function initialize() {
            var mapOptions = {
                center: new google.maps.LatLng(-34.397, 150.644),
                zoom: 5
            };
            map = new google.maps.Map(document.getElementById("map"),
            mapOptions);
            geocoder = new google.maps.Geocoder();
            bounds = new google.maps.LatLngBounds();
        }
        function addMarkerToMap(location){
            var marker = new google.maps.Marker({map: map, position: location});
            bounds.extend(location);
            map.fitBounds(bounds);
        }
        initialize();

        $("address").each(function(){
            var $address = $(this);
            geocoder.geocode({address: $address.text()}, function(results, status){
                if(status == google.maps.GeocoderStatus.OK) addMarkerToMap(results[0].geometry.location);
            });
        });

        google.maps.event.addDomListener(map, "idle", function(){
            center = map.getCenter();
        });

        $(window).resize(function(){
            map.setCenter(center);
        });

Figured it out. Added this code before map.fitBounds(bounds) and it worked;

google.maps.event.addListenerOnce(map, 'bounds_changed', function(event) {
    if (this.getZoom() > 15) {
        this.setZoom(15);
   }
});

Andrew Chalkley In your videos you do this for two markers. I have used the same code for one marker on my page I am building and it zooms in real close to that one marker. How would I fix this? Thanks!
