Rent & eviction protection

Is 3418-3420 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.

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.

Built 1906
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 6-unit, 3-story multi-family residential building at 3418-3420 19th Street, owned by 3418 19th Street LLC, was constructed in 1906 and has undergone several significant improvements over the years. Most notably, the building completed its soft story retrofit in 2019 (cost: $68,000), addressing earthquake safety concerns. The property has seen substantial electrical and structural upgrades in recent years, including multiple electrical system improvements in 2021 with new lighting, outlets, smoke detectors, and panel modifications, as well as recent plumbing work. A 2010 renovation included substantial kitchen and bathroom updates with a focus on energy efficiency.

The building has experienced several violations and maintenance issues over its history, with the most recent active concerns involving lead-based paint work practices, structural maintenance, and weatherproofing of stucco (all documented in December 2022). Historical violations include issues with stairs, egress obstruction, and various fire safety concerns, though many of these were resolved between 2010-2015. There have been multiple health and safety inspections over the years, including a current active periodic inspection from June 2023. Recent 311 calls (January 2025) suggest ongoing issues with graffiti and sidewalk maintenance in the vicinity, though these are external to the building itself.

Risk rating

How 3418-3420 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
9thpercentile

Out of 2380 buildings in this neighborhood, 2166 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
