About Measure Y

Measure Y extends until 2030 the City of San Mateo’s voter-adopted height, density, and affordable housing protections.  These protections were created in 1991 as Measure H in response to development pressures and an unresponsive City Council.  Residents realized, after their concerns were consistently disregarded, that some development standards were too important to leave to just 3 votes of the City Council on any given Monday night.  Measure H became Measure P when renewed by the voters in 2004, and Measure Y when renewed in 2020. 

 

LAND USE STANDARDS - Measure Y continues land use standards that protect residential neighborhoods and promote intensification of high density development near transit.  It allows building heights of 55-75 feet (5-7stories) and densities of 50 units per acre.  It also requires developers to provide "public benefit" in return for projects exceeding 55 feet in height. This public benefit requirement has protected a block of historic buildings along B Street in downtown and provided park, pedestrian safety and fencing improvements in the 19th Avenue Eichler neighborhood.  
 

AFFORDABLE HOUSING - To address the need for affordable housing Measure Y requires a minimum of 10% affordable below market rate (BMR) housing in every new development of more than 10 residential units.  It encourages the City Council to increase this percentage, which they recently raised to 15%.  Measure Y requirements have doubled the production of BMR housing in the city of San Mateo over the last 30 years. 
Measure Y is consistent with current state housing laws, including  AB 1505, allowing off-site building, or other alternative means of providing affordable housing. 


In accordance with long-held community values to distribute affordable housing equitably throughout the city, Measure Y does not allow use of in-lieu fees for developers to buy their way out of building the affordable units at the same time their development is built.   


GENERAL PLAN UPDATE - As part of the General Plan, Measure Y continues to allow substantial office, commercial and residential development while maintaining the community character and quality of life that we all enjoy. Millions of square feet of office space and thousands of housing units have been built within the smarter growth envelope of this balanced growth measure. Measure Y prevents 3 votes of the City Council from making changes to the General Plan during any update process. Once a revised General Plan is adopted, it can be, and should be, presented to the voters for approval.
