Housing Program

The Environmental Health Services Division is responsible for enforcing State Health Laws, quarantines and orders related to housing in the areas of interior and exterior maintenance, sanitation, and occupancy standards.

Authority to enter and conduct housing inspections is derived from the California Health & Safety Code Section 17970. In order to support the enforcement activities related to these laws, the County Board of Supervisors passed Ordinance No. 04180, to charge fees for these services.

Housing Program inspects the following facilities:

  • Multi-Unit Rental Properties
  • Hotels/Motels
  • Bed & Breakfast
  • Mobile Home Parks (within unincorporated San Mateo County)
  • Organized Camps
  • Employee Housing
  • Detention Facilities

Routine Inspections

All the above mentioned facilities are subject to routine inspections by this department and assessed an annual fee as set by County Ordinance Title 5, Chapter 5.64, §5.64.070.


Single family dwellings, duplexes and triplexes are inspected on a complaint only basis.

Complaints for the Cities of San Mateo and San Carlos are handled by their respective Code Enforcement Departments.

Complaints concerning Housing Authority, HUD, or Section 8, should be directed to the San Mateo County Dept. of Housing Authority at 650-802-3300


Once an inspection is completed, the property owner is notified, in writing, of the results of the inspection. If violations are confirmed and documented, a timeframe for compliance will be given. If additional inspections are required to attain compliance, owners may be subject to re-inspection fees.

Providing adequate housing to your tenants is a minimum requirement under State Housing Codes. The California Civil Code Sections 1941 and 1942 provide tenants with protection against unlawful evictions and other retaliatory measures such as raising rent due to repairs of a minimum requirement.
