Rent & eviction protection

Is 1417-1419 48Th 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 1906

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 two-story, four-unit multi-family residential building at 1417-1419 48th Avenue in San Francisco's Outer Sunset neighborhood, owned by Zhihui Fan and Xiang Yun Su, has a documented history dating back to 1906. The property has undergone several significant maintenance and repair projects over the years, including a reroofing project in 2018 costing $12,400, and substantial repairs to address rotted siding on the front of the building in 2012, which had been initiated in response to a complaint. Of particular note is a period of concerning safety issues in the late 1990s, including a fire incident in 1998 that required exterior repairs, followed by a series of plumbing and electrical problems documented in complaints between 1999-2000, such as bathroom leaks, kitchen appliance failures, and electrical system challenges. Historical records also show various infrastructure improvements in the 1990s, including window and door replacements, additional roofing work, and a shower stall replacement.

The building has experienced several compliance-related issues, including a 2012 complaint regarding unpermitted work on a historical building, and multiple housing inspection cases in 1994 concerning unauthorized alterations and property line disputes over pipe installations. The property has had its share of maintenance challenges over the years, with documented leaks in multiple units, and there was one incident of fire department damage to rugs in 1999. More recently, there have been two parking-related enforcement actions in early 2023 regarding driveway blockages, though these were routine parking enforcement matters rather than building-specific issues. The most recent building permit records do not show any active or pending major works, suggesting that the property has maintained a relatively stable condition in recent years, with no new significant complaints or safety issues reported since 2000.

Risk rating

How 1417-1419 48Th 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
7thpercentile

Out of 632 buildings in this neighborhood, 588 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.

Neighborhood location

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

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

Neighborhood (ZIP code)

The ZIP code captures local housing market and enforcement patterns that affect all buildings in the area.
