Builders will be automatically excluded from a supplement assessment on new construction if the property they are building will be offered for sale, and:


  • it is subdivided into five or more parcels
  • a map describing the parcels has been recorded, and
  • the zoning regulations or building permits for the parcels require that single-family residences will be constructed on them.

Exclusion for Builders of Four or Fewer Single-Family Residences


Builders of four or fewer single-family residences may be exempted from a supplemental assessment on new construction that is built for sale.


The builder must file a claim for exclusion within 30 days of starting construction. The form is available at the San Mateo County Assessor-County Clerk-Recorder's Office, Assessor's Division and should be completed and returned to that office.


If the builder does not file the form within 30 days of starting construction, a supplemental assessment for the value of the new construction is assessed to the builder upon completion of construction.


If the exclusion is granted, a supplemental assessment is not created until the property is sold.

Decline in Market Value (Proposition 8) - Property Tax Relief


Decline In ValueThe assessed value of a property should never be higher than the property's value on the open market. Occasionally, market forces and other factors will cause a property's value to decline significantly enough to create that situation. In these cases, the Assessor may lower the assessed value of any real property if it is higher than the market value as of January 1.


Each case is reviewed individually at the request of the property owner. The Assessor considers both land and improvements when determining the  January 1 market value.

Calamity Relief


Disaster ReliefIf a calamity such as fire, earthquake or flood damages or destroys your property, you may be eligible for property tax relief, provided the loss exceeds $10,000. In such cases, the San Mateo County Assessor-County Clerk-Recorder's Office, Assessor's Division will reappraise the property to reflect its damaged condition. If the property is rebuilt in a like or similar manner to the original, the property will retain its previous value for tax purposes.



To qualify for property tax relief, you must file a calamity claim form with the San Mateo County Assessor-County Clerk-Recorder's Office, Assessor's Division within one year from the date the property was damaged or destroyed.

Homeowners’ Exemption


home owener exemptionIf you own a home and occupy it as your principal place of residence on January 1, you may apply for an exemption of $7,000 from the home's assessed value, which reduces your property tax bill. There is no charge for filing for the Homeowner Exemption. New property owners will automatically receive an exemption application in the mail. Homeowner Exemptions may also apply to a supplemental assessment if the property was not previously receiving a Homeowner Exemption on the annual Assessment Roll.


Please note that California law provides for only one Homeowner Exemption per owner at their principal place of residence, so a second home would not qualify for the exemption.


San Mateo County residents may request a Homeowner Exemption claim form from this website.  Residents of other counties should contact their local assessor's office for these forms.


To request a claim form, include the property address, your mailing address and/or your Assessors Parcel Number.

Property Tax Postponement for Senior Citizens, Blind, or Disabled Persons


property tax postponment

The State Controllerís Property Tax Postponement Program (PTP) returned in 2016 after being suspended by the Legislature in 2009.

The program allows homeowners who are seniors, are blind or have a disability to defer current-year property taxes on their principal residence if they meet certain criteria including 40 percent equity in the home and an annual household income of $35,500 or less.

A postponement of property taxes is a deferment of current year property taxes that must eventually be repaid. Repayment is secured by a lien against the property.

Eligible California homeowners may postpone payment of all or part of their property taxes through the Property Tax Postponement Program administered by the State Controllerís Office.

To qualify for the program, a homeowner must meet the following criteria:

  • Be at least 62 years of age, or blind, or disabled;
  • Own and occupy the property as his or her principal place of residence (mobile, manufactured, or modular homes, whether affixed or un-affixed; floating homes and house boats are not eligible);
  • Have a total household income of $35,500 or less;
  • Have at least 40 percent equity in the property; and
  • Not have a reverse mortgage on the property.

To apply, a homeowner must file a claim form with the California State Controllerís Office. A Property Tax Postponement lien will be recorded on the home. The interest rate for taxes postponed under PTP is 7 percent per year.

Funding for the program is limited, and applications will be processed on a first-come, first-served basis. Only current-year property taxes are eligible for postponement.

Collection and Repayment Process

The homeowner may pay all or part of the balance to SCO at any time. However, postponed property taxes and interest become immediately due and payable when the homeowner does any of the following:

  • Moves from the property;
  • Sells or conveys title to the property;
  • Dies and does not have a spouse, registered domestic partner, or other qualified individual who continues to reside in the property;
  • Allows future property taxes or other senior liens to become delinquent; or
  • Refinances or obtains a reverse mortgage for the property.

A copy of the application and instructions can be downloaded here.

Requirements are subject to change without notice if the law is revised. Please contact State Controllerís Office to verify the current program requirements.
