Rent & eviction protection

Is 1243-1245 19Th Ave rent-controlled?

San Francisco's Rent Ordinance caps rent increases and provides eviction protection for most residential units built before 1979 with 2+ units. Here's how this building scores.

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.

Annual rent increase cap
5% + CPI, max 10%
Just-cause eviction
After 12 months
Local rent control likely takes priority. This building appears to fall under the local ordinance above, which is stronger than AB 1482. Where a local just-cause ordinance applies, its rules govern instead of the state cap.

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 property at 1243-1245 19th Avenue is a two-unit, two-story multi-family residential building located in the Central Sunset neighborhood. Built in 1911 and currently owned by Melissa M. Chong, this flats & duplex building has undergone several significant renovations, most notably in 2002 when comprehensive remodeling work was completed on four bathrooms, two kitchens, window replacements, and heater upgrades, costing approximately $40,000. The building's front elevation stucco was also replaced that same year. While the building has been maintained with proper permits in the past, there have been multiple concerning issues reported in recent years.

Most notably, in 2021, serious complaints were filed regarding an allegedly unauthorized in-law unit, with tenants reporting ventilation issues, address sharing problems, and heating concerns. Earlier that same year, complaints were made about indoor smoking affecting air quality through vents, and historical complaints from 1998 documented issues with broken windows and ceiling damage in bathrooms. The building's recent history shows consistent problems with driveway blocking, with multiple parking enforcement calls between 2021-2024, suggesting ongoing challenges with vehicle access. A recorded fire-related incident involving smoke detector activation due to malfunction was noted in the records, though no civilian injuries were reported. While the building has undergone necessary renovations, these recent complaints about unit legality, heating, and air quality suggest potential ongoing maintenance and compliance challenges.

Risk rating

How 1243-1245 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
9thpercentile

Out of 814 buildings in this neighborhood, 741 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
