San Diego ADUs may be rented long-term (30+ days) without restriction. Short-term rentals are governed by SDMC § 510.0101 et seq. (the four-tier STRO program). ADUs cannot operate as Tier 3 or Tier 4 STRs in most cases because those tiers require the host's primary residence. Junior ADUs are restricted to 30-day minimum rentals by SDMC § 141.0302(c)(2).
