SIDs: A Brief History
The need for Sanitary and Improvement Districts (SIDs) emerged following World War II, as returning soldiers drove a surge in housing demand.
While all SIDs generally follow a similar process, each District’s timeline may vary. Some SIDs may exist in perpetuity, while others may operate for 20 to 30 years before being annexed. The process typically includes land acquisition, District formation, installation of improvements, warrant issuance, lot sales and vertical construction, bond issuance, and ultimately the retirement of bond debt or annexation of the SID.
Step 1: Land Acquisition (12-36 months)
Step 2: SID Formation (~90 days)
Step 3: Installation of Improvements (12-18 months)
Step 4: Warrant Issuance (1-7 years)
Step 5: Lot Sales and Vertical Construction (2-7 years)
Step 6: Bond Issuance (3-7 years)
Step 7: Bond Debt Retired or Annexation (20-30 years)
