Outer Sunset, SF 94122 1894001 3 units · 2 fl · 1948

Nothing on record for this building in the last seven years, but our model still flags a rising risk of maintenance problems in the next 12 months. That forecast comes from the owner's wider portfolio and the surrounding area, not from this building's own record — treat it as a reason to ask questions, not as evidence of a problem. No public enforcement record to go on. Walk the building, ask the current tenants how repairs get handled, and get any promises in writing.

The bar and the rating point different ways because they measure different things: the bar counts DBI violations already on file, the rating forecasts the next 12 months.

Rent & eviction protection

Is 1505-1507 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.

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
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 three-unit, two-story multi-family residential building at 1505-1507 48th Avenue in San Francisco's Outer Sunset neighborhood was constructed in 1948 and is currently owned by the James J Coughlan Revocable Living Trust. The building's maintenance history shows attention to critical infrastructure, with a reroofing project completed in 1997 and remediation of dry rot issues addressed in 1993 following a pest control report.

The property has an extensive record of external maintenance issues in recent months, with numerous 311 calls primarily related to garbage and debris on the surrounding streets between July and December 2024. These reports include incidents involving hazardous waste, abandoned electronics, and illegal parking concerns, with varying outcomes including resolved cases and ongoing investigations. The building's safety systems have experienced at least two fire department responses—one for a malfunctioning smoke detector and another for a false alarm—though importantly, no civilian injuries were reported in either incident. The property's age and infrastructure history, combined with the recent pattern of external maintenance issues, suggest ongoing challenges with neighborhood cleanliness and property upkeep.

Risk rating

How 1505-1507 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
11thpercentile

Out of 632 buildings in this neighborhood, 562 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
