Rent & eviction protection

Is 1800 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 1951

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.

Just-cause eviction

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-unit multi-family residential building at 1800 48th Avenue in San Francisco's Outer Sunset neighborhood, owned by Nancy A Garcia 2006 Revoc L, was constructed in 1951 as a single-story flats and duplex structure. The building has undergone several window-related improvements, with multiple permits issued in the 1980s for window replacements, including a completed project in 2001 to replace five windows at a cost of $3,348. More recently, in April 2023, a water damage and mold complaint was filed with Housing Inspection Services, though this case is currently listed as not active. The property has experienced recurring water-related issues, as evidenced by multiple fire department responses for water problems and leaks between 2018 and 2023, though no civilian injuries were reported in any incidents.

The building's recent history shows significant concerns with exterior maintenance and environmental conditions. Between July 2023 and January 2025, there were multiple reports of garbage and debris on the property, including instances of hazardous waste, bagged garbage, and loose debris. Several graffiti incidents were reported, affecting both the public sidewalk and the mailbox. A notable noise complaint was filed in September 2024 and remains open as of the latest report. The property's maintenance issues extend to public infrastructure, with reports of a blocked sidewalk due to privately maintained vegetation in July 2024. While there have been various fire department responses to the building, including one cooking fire and several alarm/system activations, none resulted in injuries or substantial damage. The building's permit history shows attention to window maintenance and improvements, though some permits from the 1980s are listed as expired.

Risk rating

How 1800 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
28thpercentile

Out of 632 buildings in this neighborhood, 455 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
