Cow Hollow, SF 94123 0540026 8 units · 4 fl · 1907

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 2117-2127 Union St 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 1907

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.

15+ years since occupancy
Built 1907
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 four-story, eight-unit multi-family residential building at 2117-2127 Union Street in Cow Hollow, owned by Peter and Sophie Pappas, has undergone several significant maintenance and improvement projects since its construction in 1907. Most recently, in 2022, the building received a new wall furnace installation, and in late 2019, Unit 1 underwent a comprehensive $36,000 kitchen and bathroom remodel, including electrical upgrades and the installation of new smoke detectors. The property has faced some notable challenges over the years, including a significant incident in early 2017 involving flooding that resulted in mold issues, with reports suggesting the presence of asbestos and lead, though these problems were eventually addressed through inspection and remediation processes. A concerning pattern emerged in 2008 with multiple housing code violations related to fire safety and security, though all were promptly abated by December 2008. The building's history also includes unauthorized construction of a roof deck in 2017, which led to a violation notice that was eventually resolved, and a 2002 complaint regarding fire escape maintenance. Regular maintenance work has been performed over the years, including plumbing updates such as water heater installations in 2012 and 2013, gas line repairs, and various structural improvements including stair replacement in 1998 and re-roofing work in 2000. The most recent building-related activity was a moving sign request in January 2024, though this was denied due to non-payment issues. The property has maintained active compliance with housing regulations since 2008, with no recent major violations or complaints on record.

Risk rating

How 2117-2127 Union St'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
18thpercentile

Out of 861 buildings in this neighborhood, 706 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.

Building size

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

Neighborhood (ZIP code)

The ZIP code captures local housing market and enforcement patterns that affect all buildings in the area.
