371 Guerrero St

Mission Dolores, SF 94103 3555030 4 units · 2 fl · 1939

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 371 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.

Built before 1979
Built 1939
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 1939
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 4-unit, 2-story multi-family residential building at 371 Guerrero Street in Mission Dolores, owned by Marchi & Smith Family Trust, has undergone significant infrastructure improvements since its construction in 1939. Most notably, in late 2024, the building completed fire alarm system upgrades to comply with current safety standards, including installation of low-frequency sounders in sleeping areas and compatibility updates to the fire alarm control panel. The building has received substantial mechanical upgrades over the past decade, including a comprehensive repiping of the plumbing system in 2011, house trap replacement in 2009, and multiple wall furnace installations and replacements between 2007-2008.

The property has maintained responsiveness to safety and compliance issues, as evidenced by prompt remediation of violations from a 2011 routine inspection, which included work on the central alarm system, fire extinguishers, and self-closing exterior doors. While there have been several quality-of-life issues reported through 311 calls in recent years, including graffiti (2023), sidewalk defects (2023), and waste removal needs, these cases were generally addressed through normal municipal processes. The building's maintenance history shows regular attention to infrastructure needs, though some permits from earlier years, such as a 1999 reroofing project, are listed as expired. The most recent building improvements, particularly the fire safety upgrades, demonstrate ongoing commitment to maintaining current safety standards, though the building's age and history suggest regular maintenance and updates have been necessary to address its infrastructure needs over time.

Risk rating

How 371 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
62ndpercentile

Out of 799 buildings in this neighborhood, 304 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 (ZIP code)

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

Neighborhood location

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