Nob Hill, SF 94109 0217018 12 units · 3 fl · 1922

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.

The bar and the rating point different ways because they measure different things: the bar counts DBI violations already on file, the rating forecasts the next 12 months.

Rent & eviction protection

Is 1642 Larkin 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.

Annual rent increase cap

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

1642 Larkin Street is a 3-story, 12-unit multi-family residential building located in Nob Hill, owned by Mecham Family LP and constructed in 1922. The building has undergone several significant safety and infrastructure improvements in recent years, including a completed soft-story retrofit in 2017 (with plywood shear walls and steel frames added at the ground floor), a comprehensive fire alarm system upgrade in 2023 to meet fire code requirements (including low-frequency sounders and new fire panel), and the installation of individual subpanels in most units in 2018 to improve electrical service. The building has an active fire safety maintenance record, with three fire alarm system complaints between 2020-2022 that were corrected, and three carbon monoxide-related incidents (two in 2020, with no injuries reported).

Historical maintenance records show consistent upkeep, including reroofing projects in 1989 and 2015, and temporary shoring work in 2004. The building experienced multiple fire code violations in 2001 related to fire extinguishers and fire proofing, all of which were abated by June 2001. A routine inspection in 2009 resulted in violations for self-closing exterior doors and hot water heater seismic bracing, which were also resolved. Recently, there have been some infrastructure challenges, including two sewer backup incidents in 2022 and multiple parking enforcement calls for blocking driveways between 2022-2024. The property is classified as Tier 3 in the Soft Story program, with all required work completed and a Certificate of Final Completion issued. The most recent building improvements and active maintenance of fire safety systems suggest a committed approach to maintaining building safety standards.

Risk rating

How 1642 Larkin 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
20thpercentile

Out of 1125 buildings in this neighborhood, 900 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.

Building size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

Neighborhood location

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