Bernal Heights, SF 94110 5503016 9 units · 3 fl · 1909

Nothing on record for this building in the last seven years, but our model still flags a rising risk of maintenance problems in the next 12 months. That forecast comes from the owner's wider portfolio and the surrounding area, not from this building's own record — treat it as a reason to ask questions, not as evidence of a problem. 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 3129-3139 Folsom 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.

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 1909
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 9-unit multi-family residential building at 3129-3139 Folsom Street in Bernal Heights, owned by Wells Eryn Rachel, is a three-story structure built in 1909. The property has undergone several significant improvements over the past decade, most notably completing a mandatory soft-story retrofit in 2015 (Tier 3) that included the installation of shearwalls, grade beams, and epoxy anchors for seismic safety. Recent maintenance includes a bathroom remodel in 2022 ($10,000), reroofing in 2019 ($22,000), and various infrastructure upgrades such as furnace replacements and fire safety improvements. Notable historical issues were documented in the early 2000s, including a rodent infestation, mold problems, and various building code violations, though all of these were resolved by 2005. The building received significant electrical system upgrades in 2010-2011, including complete rewiring of all units and installation of smoke detectors. Recent maintenance has focused on individual unit improvements, with multiple bathroom renovations and system upgrades documented between 2012 and 2023. There have been no active housing code violations since 2005, and the building's recent maintenance record suggests ongoing investment in property upkeep. Recent 311 calls related to the property have primarily concerned street cleaning and sidewalk maintenance issues rather than building-specific concerns, with the most recent being a sewage backup incident in June 2024 that was promptly resolved.

Risk rating

How 3129-3139 Folsom 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

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.

Building size

Neighborhood (ZIP code)

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