593 Pennsylvania Ave

Potrero Hill, SF 94107 4104011 3 units · 1 fl · 1900

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 593 Pennsylvania 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 1900

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 1900
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 property at 593 Pennsylvania Avenue in Potrero Hill is a century-old, one-story multi-family residential building containing three units, currently owned by Peter Kai Ming Chen. The building's maintenance history shows several significant infrastructure updates, with the most recent being a complete side sewer replacement in October 2023, which followed the discovery of disintegrated components during work on the new sewer lateral. In 2015, interior repairs were undertaken to address dry rot, including the removal and replacement of approximately 100 square feet of drywall and tile, while earlier structural improvements included window upgrades in 1989 (installation of six aluminum windows) and major work in 1984 involving roof replacement and front wall construction.

The building has faced some administrative scrutiny, evidenced by a complaint in 2005 regarding possible illegal units and concerns about property encroachment, though this case was closed within a month. More recently, between 2017 and 2022, there were multiple municipal service calls related to urban maintenance issues, primarily concerning street cleaning, tree maintenance, and waste removal in the vicinity of the property. Notable among these was the emergence of tree root-related sidewalk damage (report dated May 2022) and several instances of human or animal waste reported on or near the property's private pathways in August 2019. The most recent tree maintenance requests from 2017 indicate ongoing attention to the building's immediate environment, though many of these exterior issues have been handled by city services rather than direct building management intervention.

Risk rating

How 593 Pennsylvania 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
36thpercentile

Out of 726 buildings in this neighborhood, 465 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.

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.

Number of floors

Building height affects maintenance complexity and is one of the size signals the model uses.

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.
