Rent & eviction protection

Is 1380 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 1975

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.

Annual rent increase cap

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 8-unit, 2-story multi-family residential building at 1380 48th Avenue in the Outer Sunset, owned by the Giosso Family Living Trust and constructed in 1975, has undergone several significant structural and safety improvements over the years. Most recently, in May 2024, the building received a comprehensive electrical upgrade with the replacement of the house sub-panel in the garage and individual sub-panels in all six units. The building completed its mandatory soft-story retrofit in 2016 at a cost of $45,000, demonstrating compliance with San Francisco's seismic safety requirements. There have been three documented reroofing projects: in 1989, 2012 ($13,000), and most recently in 2019 ($5,000).

The property has experienced several fire safety-related issues in the early 2000s, including multiple violations in August 2002 concerning combustible storage in the garage and egress obstructions, as well as issues with gas meter documentation and fire extinguisher maintenance. These violations were all abated by November 2002. Two complaints about unpermitted roofing work were filed in 2005 and 2017, though both cases are now inactive. A routine fire alarm systems inspection in July 2007 resulted in condition correction. The building's recent maintenance history shows no active safety violations or recurring maintenance issues. While there have been multiple parking-related complaints near the property between 2018 and 2024, these are external issues not directly related to the building's condition or safety.

Risk rating

How 1380 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
5thpercentile

Out of 632 buildings in this neighborhood, 600 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.

Number of units

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

Neighborhood location

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

Building size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.
