Rent & eviction protection

Is 451 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.

Built before 1979
Built 1965
2 or more units
4 units
Property type
Multi-Family Residential
Zoning

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 1965
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 4-unit, 2-story multi-family residential building at 451 19th Avenue in the Central Richmond neighborhood, owned by Gipper 2000 LLC, has experienced persistent water-related issues since its construction in 1965. The building has undergone several significant improvements over the past three decades, including window and slider replacements in 2012, a complete reroofing in 2012, and stair and deck repairs in 2013. A notable cluster of water-related complaints occurred between 2013-2022, with multiple incidents of water intrusion, dampness, and mold growth, particularly during rainy periods, though some of these issues were reportedly addressed through building permits for window repairs and stucco work in 2017.

The property has experienced maintenance challenges with various building systems, including electrical, plumbing, and fire safety features. A significant cluster of violations was recorded in October 2002, including issues with fire proofing, smoke enclosure doors, gas utility shutoff tools, stairs, combustible storage, and electrical outlets, though these were all abated by March 2003. Recent service requests and complaints, particularly during 2023-2024, have primarily concerned parking issues and debris removal, suggesting improved overall building conditions. The most recent building complaint from October 2022 noted water intrusion, insect/rodent issues, and ceiling leaks in the garage, though these issues were marked as not active in August 2024. The property's maintenance history demonstrates regular upkeep through various building permits, including a recent repair related to wood siding and bay window leaks in 2017, though some recurring water-related issues suggest ongoing challenges with moisture management in the building.

Risk rating

How 451 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.
