Rent & eviction protection

Is 3428-3434 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.

15+ years since occupancy
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 3428-3434 19th Street, owned by 19th Alliance Group LLC, has undergone significant renovations and faced multiple maintenance challenges since 2021. Most notably, powers and utilities upgrades were completed in 2022, including comprehensive electrical rewiring with new 80-amp subpanels (July 2022), furnace installations, and main sewerline replacements in the lightwell (January 2022). The building faced serious violations in 2021 regarding water damage, heat provision, and lead paint hazards, which were ultimately abated by August 2022. During the summer of 2022, there were several complaints about unauthorized demolition work in units 3432 and 3432A, though these were subsequently resolved. More recent improvements include a new fire alarm system installation (filed June 2023) and bathroom renovation work (completed October 2023), demonstrating ongoing investment in building infrastructure and resident amenities.

The building's maintenance history shows a combination of proactive upgrades and reactive repairs, with several permits indicating efforts to address various issues. These include roofing work (August 2022), exterior dryrot repairs (October 2021), and multiple plumbing updates. The property has experienced recurring issues with debris and waste management in the vicinity, as evidenced by multiple 311 calls for street and sidewalk cleaning between late 2024 and early 2025, though these appear to be primarily related to external maintenance rather than building conditions. While the property has faced numerous challenges over the past few years, the resolution of major violations and recent improvements suggest progress toward maintaining building standards and resident comfort.

Risk rating

How 3428-3434 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

Grade A–B — Low risk

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

Grade C — Moderate risk

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

Grade D–F — High risk

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