Important Tips When Using the Database:

When entering an address, do not include the type of street. For example, if the address is 26 Corte Madera Avenue, enter 26 Corte Madera (without Avenue).

For those addresses with “East”, “West,” “North,” “South”, try entering the first initial, followed by the address. For example if the address is 19 East Blithedale, enter 19 E Blithedale. In some instances, the full address name may work as well.
