Bernal Heights, SF 94110 6595015A 4 units · 3 fl · 1912

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 29-39 27Th 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 1912
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 29-39 27th Street property in Bernal Heights is a 4-unit multi-family residential building constructed in 1912, currently owned by the Mueller Philip A Trust The. The building has undergone several significant improvements and faced various maintenance challenges over the years. Most notably, in 2016, the property completed a mandatory soft-story retrofit as a Tier 3 building, achieving compliance with seismic safety requirements. The building has experienced multiple water-related issues, including a 2014 flood incident from a leaking pipe that caused kitchen damage, and more recently in September 2024, there was a sewage backup discharge from a side sewer vent that required resolution.

The property has a history of building maintenance concerns, particularly in the mid-2000s. In 2007, multiple violations were recorded including problems with mold/mildew, damaged interior surfaces, plumbing issues, and problems with fire safety equipment, though these were all abated by September 2009. Earlier issues included a significant repair project in 2005 to address dry rot in the rear stairs, which had initially triggered building violations for unauthorized repairs. Between 2021 and 2023, there were several attempted electrical upgrades, including a 200-amp service upgrade and car charger installation, though these permits were ultimately cancelled or not completed. The most recent construction-related activity on record was a 2016 permit revision for concrete footing work at a door infill, which was filed but remains in an indeterminate status.

Risk rating

How 29-39 27Th 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
30thpercentile

Out of 1276 buildings in this neighborhood, 893 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.

Neighborhood location

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

Neighborhood (ZIP code)

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