Statewide backstop · AB 1482

California Tenant Protection Act of 2019

Even when a building isn't covered by local rent stabilization, the statewide Tenant Protection Act (AB 1482) may still apply. It caps annual rent increases and requires the landlord to state a legal reason to end most tenancies.

15+ years since occupancy
Built 2019
Annual rent increase cap
5% + CPI, max 10%
Just-cause eviction
After 12 months
Likely exempt from AB 1482. Housing with a certificate of occupancy issued within the previous 15 years is exempt from the state rent cap and just-cause rules.

AB 1482 does not apply to single-family homes and condos unless owned by a corporation, REIT, or an LLC with a corporate member; to owner-occupied duplexes; or to deed-restricted affordable housing. The Act is in effect until January 1, 2030. Not legal advice — see the California landlord–tenant guide.

Initial analysis

The Kwok Family Trust owns this property, which consists of a four-story, two-unit residential building with two vehicle spaces, constructed in 2013-2014 in San Francisco's Central Sunset neighborhood. The building underwent significant safety upgrades in 2018, including the comprehensive installation of a fire sprinkler system throughout the building (comprising 69 sprinklers) at a cost of $37,700, along with a sprinkler monitoring system installed in 2019. The new construction phase (2013-2014) included complete plumbing installations for two units, electrical systems with a 200A service, and other essential infrastructure.

More recently, there has been a pattern of parking-related issues near the property, with multiple complaints about driveway blocking between late 2023 and 2024. According to 311 call records, there were nine reported incidents of driveway blocking, with six resulting in citations and three cases where officers were unable to locate the offending vehicles. Additionally, there were reports of garbage and debris in the vicinity in November 2024, though no work was deemed necessary. The building's construction history shows that appropriate permits and inspections were followed, with completion of major systems including electrical, plumbing, and fire safety measures, suggesting compliance with necessary building codes and safety requirements.

Risk rating

How 1271-1273 19Th Ave's risk score is calculated

We trained a model on 7 years of SF DBI inspection data — notice of violation filings, complaint history, and owner track records. It estimates the probability that DBI inspectors will issue a Notice of Violation at this address in the next 12 months. Lower % = safer.

What the score means for you

Lower risk — safer than most nearby

DBI rarely finds violations here. Strong maintenance history and a clean complaint record.

Typical — about average for the neighborhood

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Higher risk — riskier than most nearby

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.

Neighborhood percentile
99thpercentile

Out of 814 buildings in this neighborhood, 8 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.

Hello, I am submitting this complaint anonymously regarding suspected illegal short-term rental activity at: • 1267 19th Ave, San Francisco • 1271–1273 19th Ave, San Francisco These two adjacent buildings appear to be operated together by the same family, with multiple Airbnb listings distributed across different family members’ names. People involved (as shown on listings): • Judy Kwok (mother / owner) • Maximilian Kwok (son) • Kimberly Tseng (son’s wife) • Al Kwok (deceased father – still listed on at least one Airbnb profile) • Victoria Kwok (daughter, now living in the East Bay) Active Airbnb listings observed: 1271–1273 19th Ave: • “Sunny Rooms” (top floor, physically connected by stairway to Maximilian/Kimberly’s residence): https://www.airbnb.com/rooms/1016637356063563355 • “Comfortable Home” (second floor, listed under Kimberly Tseng): https://www.airbnb.com/rooms/1471130499500942982 There is also a bottom-floor studio unit in this building that appears to be rented short-term, but I was unable to locate the current Airbnb listing. It may now be rented outside Airbnb. 1267 19th Ave (where Judy Kwok lives): • Bedroom/office (monthly): https://www.airbnb.com/rooms/1135124809472163540 • Bedroom/loft (monthly): https://www.airbnb.com/rooms/624238249806327544 • 2-bedroom “Airy Apt” (co-hosted by Judy Kwok, Maximilian Kwok, and Al Kwok, who is deceased): https://www.airbnb.com/rooms/1360254377030299397 Summary of concerns: 1. Multiple listings appear to be controlled by the same household/family across both buildings, which seems to exceed the one-primary-residence-per-person requirement. 2. Maximilian Kwok and Kimberly Tseng live together at 1271–1273 19th Ave, yet separate Airbnb units in the same building are listed under each of their names. 3. Units in the 1271–1273 building are physically connected via internal stairways (some locked or inaccessible) but marketed as separate rentals. 4. Victoria Kwok previously claimed a unit as her primary residence but moved to the East Bay. There was prior city enforcement related to this. Despite this, listings appear to have continued under family members’ names. 5. At 1267 19th Ave, three Airbnb listings are active despite Judy Kwok residing in only one unit. 6. Al Kwok has passed away but remains listed as a host/co-host on at least one active Airbnb listing. Overall, this appears to be a coordinated short-term rental operation across multiple units and buildings using different family members’ names, rather than independent primary residences. Please investigate compliance with primary residence requirements, registration validity (including listings under a deceased individual), and whether these units are being operated as a commercial STR operation. Thank you for reviewing. Anonymous Sent with Proton Mail secure email.
