Show your business complies with the Equal Benefits Ordinance

Time:

A few minutes to a few weeks

To comply, your business needs to provide the same benefits to all your employees. This is the same for employees in same-sex and different-sex domestic partnerships and marriages. You need to include this in your employee policies before the City will confirm that you comply. Read detailed information here.

The Contract Monitoring Division reviews materials closely and will work with you throughout the process. Every business is different and some may need to create new policies from scratch. Because of this, the process can take anywhere from one day to several weeks.

  1. Prepare 2 documents to upload:
    1. Employee Memorandum (template)
    2. Number of employees. Examples of compliant documents include Form W-3, Form 941, or DE 9C form. Redact confidential employee information.
  2. Login to SF City Partner
  3. Click "Certifications" on the righthand side
  4. Click "12B Declaration"
  5. Complete form
    1. Click tab: "Add A New Value"
    2. On the search page, ensure the SetID field is set to "SHARE"
    3. If the Supplier ID or Bidder ID does not automatically appear when searching, enter the number
    4. Under Declaration Type, select Bidder or Supplier (if you already have a Supplier ID, select Supplier, otherwise select Bidder)
    5. Click "Add"
    6. Follow the prompts, including uploading your 2 documents
  6. Click "Submit"
