Bernal Heights, SF 94110 5504007 4 units · 1 fl · 1924

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 3101-3103 Harrison 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 1924
2 or more units

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

Based on SF Assessor records. Not legal advice — confirm with the SF Rent Board.

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.

Built 1924
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-unit apartment building at 3101-3103 Harrison Street in Bernal Heights, built in 1924 and currently owned by Johnnie & Hunter I Thompson, has undergone several significant improvements over the past decades. Most recently, in 2021, the property received updates to its plumbing and electrical systems with the installation of an electric water heater and related electrical work in the laundry area. Between 2012-2017, substantial renovations were completed, including comprehensive bathroom remodels in multiple units, window replacements (with fire safety considerations including escape routes), and security gate enhancements for first-floor units. Historical records show earlier improvements including reroofing work in 1994.

Of particular concern are the multiple fire code violations documented between 2017 and 2024, with the most recent violation issued in November 2024 showing a pattern of recurring safety issues that have generally been addressed but indicate ongoing compliance challenges. The building has also experienced occasional maintenance issues, as evidenced by routine housing inspections in 2002, 2008, and 2011. More recently, there have been multiple reports of garbage and debris issues in the vicinity of the property in early 2025, though these appear to be related to street cleaning matters rather than building-specific problems. The property has received regular maintenance improvements over the years, including the installation of safety features such as smoke detectors and updated electrical systems, though the recurring fire code violations suggest an area requiring ongoing attention.

Risk rating

How 3101-3103 Harrison 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
43rdpercentile

Out of 1276 buildings in this neighborhood, 727 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

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

Neighborhood location
