Outer Sunset, SF 94122 1802047 4 units · 2 fl · 1971

Nothing on record for this building in the last seven years. Our model still sees a moderate chance of maintenance problems in the next 12 months, from the owner's wider portfolio and the surrounding area rather than from anything recorded here. No public enforcement record to go on. Walk the building, ask the current tenants how repairs get handled, and get any promises in writing.

Rent & eviction protection

Is 1370 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 before 1979
Built 1971

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 1971
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

This two-story, four-unit multi-family residential building located at 1370 48th Avenue in the Outer Sunset neighborhood was built in 1971 and is currently owned by the Dante And Mary Giosso Family. The building has undergone two significant reroofing projects - one in 1994 (which expired) and a completed project in 2015 costing $8,500. The property has maintained regular housing inspections in 2000 and 2002, both of which were completed without noted follow-up issues. A single alarm system activation incident occurred (date not specified), which was determined to be unintentional with no civilian injuries or actual fire.

Recent conditions in the vicinity of the building show recurring concerns with parking violations and street cleanliness. Between 2019 and 2024, there were multiple documented instances of vehicles blocking driveways or parking on sidewalks, with at least three vehicles towed as a result. The area has experienced ongoing issues with loose garbage and street cleaning needs, as evidenced by multiple 311 calls regarding general cleaning requirements. The most recent incident reported in December 2024 involved human waste or urine on the street, though this was resolved. In terms of building-specific activities, there is a historical planning record (now closed) relating to a proposed construction project for an 8-unit building with parking spaces, though this appears to be unrelated to the current property.

Risk rating

How 1370 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
20thpercentile

Out of 632 buildings in this neighborhood, 506 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.

NOV rate, owner's portfolio

Per-building NOV rate across everything this owner manages — high rates signal pattern neglect.
