Initial analysis

The 12-unit, 3-story multi-family residential building at 2845 Pierce Street in San Francisco's Cow Hollow neighborhood, managed by Pierce & Union St Partners, was built in 1924 and has undergone significant recent upgrades and renovations. Between 2021-2022, all units (101, 103, 201, 203, and 301,303) received substantial improvements including kitchen relocations, bathroom rehabilitations, and the installation of washer/dryer facilities, with individual unit renovation costs ranging from $20,000 to $65,000. The building has also completed important safety upgrades, including a comprehensive fire alarm system replacement in 2022 with new devices (wireless to hardwired conversions) and low-frequency sounders in sleeping areas, costing approximately $35,000.

The property has an active violation as of November 2024 regarding the boiler permit (serial no 756921-201802), with previous historical issues related to boiler permit renewals noted in 2018, 2014, 2013, and 2010. The building's soft-story retrofit requirements have been completed and certified as Tier 3 compliant. Historical complaints from 2008 about detached stucco on the south elevation and various routine maintenance issues have been addressed. While there have been periodic complaints about boiler permits and some fire safety inspections (including blocked exits and alarm systems), these matters were generally resolved through proper corrections or demonstrated no merit. Recent 311 calls have mostly related to standard issues like recycling collection noise and tree maintenance. The building's infrastructure has been maintained with significant investments, including a boiler replacement in 2018 and domestic hot water system updates.

Risk rating

How 2845 Pierce 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

Grade A–B — Low risk

DBI rarely finds violations here. Strong maintenance history and a clean complaint record.

Grade C — Moderate risk

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Grade D–F — High risk

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.

Neighborhood percentile

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.
