In San Diego, Accessory Dwelling Units (ADUs)--granny flats or casitas--were designed with a clear purpose: to provide much-needed, long-term housing for our teachers, students, and families.
Instead, hundreds of these units have been illegally converted into full-time short-term rentals.
Our volunteer coalition fights to ensure these homes are used for people, not portfolios.
Through broad data analysis and neighbor-led reporting, we are holding illegal short-term rental operators accountable.
300+ Instances Reported: We have identified and reported over 500 cases of illegal ADU usage as Airbnb to city officials.
67% Success Rate: Of those reported cases, most have already been closed, with over 150 units successfully returned to housing.
The conversion of ADUs into short-term rentals isn't just a violation of the San Diego Municipal Code; it is a direct assault on housing affordability. When sellers and buyers assume an ADU can be used as a "mini-hotel," it creates an artificial price floor on houses with ADUs.
15-20% Price Inflation: Properties with ADUs are often sold at a 15-20% premium based on projected STR revenue. This prices out real families looking for live-in caregivers or to support multi-generational living.
Ethical Implications: Every ADU used as a vacation rental is a door closed to a San Diegan in need of a home.

We are proud to assist the City of San Diego in addressing violations.
The era of "investor-first" ADU usage is ending. The city has stepped up enforcement by:
Issuing Inspection Warrants: Targeting properties where illegal modifications and unpermitted short-term stays in ADUs have been documented.
Conducting Civil Enforcement: Pursuing legal action to shut down illegal operations and recover unpaid taxes and fines.
Imposing hefty fines: Up to $1,000/day per active violation.
"Our goal is simple: to protect the integrity of our neighborhoods and ensure that housing remains accessible for those who actually live and work in San Diego."
