Registration checklist

  1. 1
    Check your precinct first
    Confirm no precinct-level ban covers the address, since voters can outlaw shared housing block by block.
  2. 2
    Apply directly to BACP
    Submit complete, accurate application details to BACP yourself, not through a platform, with acceptable ID.
  3. 3
    Pay and get the number
    Complete the $250 annual registration payment on the Shared Housing Registration Portal, then list the registration number on approved platforms.

What could change this verdict

Your HOA
Your building or condo association can ban STRs independently of the city, so read the CC&Rs before buying.
Rule changes
City Council keeps tightening the rules, including precinct opt-outs and pending renter-protection bills, so recheck the ordinance before underwriting.
