Rent & eviction protection

Is 2175 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 1965

Likely rent-controlled. Building age and unit count suggest this property falls under San Francisco's Rent Ordinance.

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 two-unit residential building at 2175 48th Avenue in the Outer Parkside neighborhood, owned by the Dubner Family/survivors Trust, has undergone several significant improvements and faced some notable challenges in recent years. Built in 1965, this two-story flats and duplex structure has seen recent attention to its exterior, with two completed projects in 2023: the installation of energy-efficient wood aluminum clad windows ($7,500) and replacement of cedar shingles with new cedar shingle panels on the top story's front and back, including window and door trim ($18,000). More concerning was a series of housing violations filed in April 2021 regarding inadequate heating and missing smoke/carbon monoxide alarm documentation, which were not resolved until March 2023, including a final warning letter issued in February 2022.

The building's maintenance history shows attention to structural elements, with previous work completed in the 1980s-1990s including concrete step replacements and proposals for ground floor additions (though one addition proposal was ultimately cancelled). The property has faced various challenges typical of the neighborhood, with multiple instances of graffiti reported in 2023, which require special attention due to pandemic-related enforcement backlogs. Other recent municipal interactions include sidewalk-related issues in 2020 involving possible sewer problems and lifted tree roots, as well as various maintenance matters such as illegal postings, hazardous materials, and debris, all of which have been resolved. The building's recent improvements (windows, shingles) demonstrate ongoing maintenance and upgrading of the property, though the heating and safety violations indicate there was a period of inadequate building systems that required attention before being brought into compliance in 2023.

Risk rating

How 2175 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
90thpercentile

Out of 207 buildings in this neighborhood, 21 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
