Rent & eviction protection

Is 4135-4137 19Th St 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.

Built before 1979
Built 1900

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 1900
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 two-unit residential building at 4135 19th Street, owned by David J. and Cynthia J. Fleig, is a two-story flats and duplex structure built in 1900 located in the Eureka Valley/Dolores Heights neighborhood. The property is currently undergoing significant renovations, with several active permits issued in late 2024 and early 2025. These improvements include selective non-structural exploratory demolition of drywall, electrical rewiring work, and the installation of a new bathroom exhaust fan with ducting. The electrical upgrades are substantial, involving the installation of 10 lights, 20 switches, 15 receptacles, and 2 fans in the upper unit. The building has a documented history of seismic improvements, with multiple permits issued between 1994 and 2005 for various structural upgrades, including the installation of moment frames and replacement of support columns.

Recent incidents reported through the city's 311 system include an open noise complaint regarding amplified sound from October 2024, and previously recorded issues with garbage and debris (August 2024, resolved), a blocked driveway (November 2021, resolved), illegal postings (October 2019, resolved), hazardous materials on the street (January 2017, resolved), and a damaged tree (October 2013, resolved).

Risk rating

How 4135-4137 19Th St'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
49thpercentile

Out of 1278 buildings in this neighborhood, 652 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.

Model explanation

What's driving this score

The three data points that most influenced this building's risk rating — ranked by the weight the model placed on each one.

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.

Building permits, owner's portfolio

Permits pulled across all of this owner's buildings over 7 years.
