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 55-59 Guerrero 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.

Built 1908
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 three-unit multi-family residential building at 55-59 Guerrero Street, owned by Jorge Ohy, is a three-story flats and duplex structure built in 1908 located in the Mission Dolores neighborhood. The building has undergone several significant renovations and maintenance updates over the past 13 years, with particular attention paid to unit modernization and safety improvements. Major updates in 2011-2012 included the complete replacement of rear stairs, installation of three new toilets and sinks, addition of tankless water heaters, and electrical system improvements including the installation of new subpanels and laundry facilities. A notable safety concern was addressed in 2012 when multiple street space permits were issued, indicating work on the public right-of-way.

The building experienced a concerning incident in April 2007 regarding an unstable overhang with heavy plaster moldings that posed a potential safety risk to pedestrians, though this issue was resolved by June 2007. While there were multiple permit violations noted in 2007 related to building permits and exterior maintenance, these were also abated within the same timeframe. More recently, there have been several parking-related issues in front of the building, with multiple citations issued between 2018 and 2022 for vehicles blocking driveways, though these are street-related matters rather than building-specific concerns. Additional minor issues in the surrounding area have included graffiti (2022), general street cleaning needs (2021), and one report of a damaged tree (2018), all of which were addressed by city services.

Risk rating

How 55-59 Guerrero 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
37thpercentile

Out of 799 buildings in this neighborhood, 503 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
