FAQs for San Mateo County, California - Cities Map
How do you see Google Maps with city limits? Just follow the quick steps above and you will see the incorporated limits for U.S. cities displayed on a fully-interactive Google Map.
Answer questions such as:
– What city is this address in?
– Is this address in an unincorporated area?
– Who has jurisdiction at this address?
– Is this location on the map part of a city or town?
– What county and state is this city part of?
Background: As a general rule, “property within a city’s limit is subject to city taxation and city regulation, and expects city services [provided by the city government]. Areas outside any city’s limit are considered to be unincorporated, and in most U.S. states they are by default regulated and taxed by the county. In others, areas outside a city’s limit fall within another type of local government, such as the civil township (a division of a county).” More details here.
Why was this tool created? You can only view ONE city’s boundaries at a time on Google Maps, whereas this tool incorporates a Google Maps municipal boundaries overlay so you can see a map with ALL city limits anywhere in the United States.

- The Search places box uses a standard Google Maps geocoding engine, therefore you can type street addresses, road names, points of interest, and GPS coordinates (see * above) to see what city that location is part of
- Many of the map layers from which this information is extracted are very large, so it may take several seconds for all of the map layers to finish drawing
- Because the map layers are large, boundaries will not be shown if you are zoomed out too far
- Note that typing an address will zoom in the map very close, whereas typing a city or county by itself will show you a map with a wider view
- Disclaimer: While the number of decimals in the latitude and longitude displayed for the map marker may imply a positional accuracy of within a few feet, note that Google Maps and the source data may not be that accurate. Accordingly, this tool should not be used for legal nor surveying purposes or anything beyond entertainment value.
