Permit Sonoma is charged with the responsibility of assigning new addresses and adjusting existing physical addresses within the unincorporated areas of Sonoma County. The goal of proper address assignment is to bring addressing in Sonoma County to consistent standards and to support emergency response efficiencies, thereby providing for the safety of Sonoma County residents.
Sonoma County is not requiring that our address be changed right now. Can we change it anyway?
Yes. Please go to Permits Online to begin the process. All new addressing is subject to Sonoma County addressing standards. The cost to re-address your residence is $81.00 (FY 2021-2022).
Why do I have to change my address?
Primary access to your property may have changed, your address may have been on a previously unnamed road, or out of sequence per addressing standards. Your new address will make it more efficient for fire, emergency medical services, and law enforcement personnel to find your home in the event of an emergency. Additionally, delivery and service providers will be able to find your address more easily.
How are new addresses chosen?
My parcel is vacant, why doesn’t it have an address?
Vacant parcels are not addressed. Unless there is activity requiring certain permit types, such as building a new residence, your parcel will remain un-addressed. For answers to specific questions about your parcel, email PermitSonoma-Addressing@sonoma-county.org
When does a parcel receive an address assignment?
Certain permits will initiate an address assignment. Some of these permits include a new residence, a new Additional Dwelling Unit (ADU), a permit for electricity for a well, among others. For answers to specific questions about your parcel, email PermitSonoma-Addressing@sonoma-county.org
What are the requirements for posting house numbers on your premises?
New address numbers must be posted where your driveway meets the road and must be visible from both directions of travel on that road. Address numbers must be posted on your house in a place where they will be visible from the road or from your primary driveway. The numbers must be reflective, must contrast with their background, and they must be at least four inches tall. The numbers on your mailbox must be visible and match your address. For a complete listing of County address number specifications go to Chapter 13 – Sonoma County Fire Safety Ordinance, Article V. Fire Safe Standards, Division C. Signing and Building Numbering
Why do I have to fill out a Change of Mailing Address form for the Assessor if Permit Sonoma has notified the Assessor of my address change?
We will notify the County Property Tax Assessor that the physical street address of your property has changed. Only you, or your authorized agent, are authorized to notify the Assessor of a mailing address change. This is to ensure that your property tax bill is mailed to the correct address. Your mailing address may be different than the property address if you own more than one property, use a post office box, or are out of state/country. Remember, you are responsible for paying your taxes by the due date, even if you do not receive a bill.
Will the title of my property be affected by the address change?
No. An address is not part of the legal description of your property. The legal description is contained in the deed and in the Preliminary Title Report you obtained prior to purchase.
Do I need to notify my lender about this new address?
Yes. You should notify your mortgage holder, property insurer, other creditors, issuers of other types of insurance (life, health, personal property, etc), in addition to service providers, and any others with whom you do business.
When do I begin using my new address?
You may begin using your new address as soon as you receive the official notification letter from Permit Sonoma. It may be a few months before businesses and government agencies update their records. If anyone questions your new address, you may provide them with a copy of the official notification letter.
What happens to mail with my old address on it?
We will notify your local post office of your new address. The postal delivery system will cross reference your old address to your new address. For best service, either complete a Change of Address Packet by calling 1-800-ASK-USPS or use the United States Postal Service website to submit a change of address online.
