Initial analysis

The property at 1722-1726 Pierce Street in Lower Pacific Heights is a two-story multi-family residential building constructed in 1900, containing three units and classified as Flats & Duplex. Recent activity on the property has been significant, particularly in 2022-2023, with several major renovations including electrical upgrades (rewiring of knob and tube system, new recessed lighting, and subpanel installation), bathroom modifications, and stair replacements. Multiple building complaints were filed in 2023 regarding construction activity, including concerns about unpermitted work, hazardous materials, and foundation work, though these complaints were generally addressed through permit acquisition or cessation of work.

The property has a history of code compliance issues, most notably in 2003-2004 when violations were documented regarding unauthorized residential hotel use, safety concerns, and maintenance issues, though these violations were resolved. Earlier records show various improvements including plumbing repairs to address a 2002 leak complaint, electrical system upgrades, and foundation work. Recent permits (2022-2023) indicate ongoing investment in property improvements, including a $12,000 stair replacement project completed in 2023 and bathroom renovations costing $40,000 in 2022. The building's ownership is held by the Lee W Hopfenspirger Revocable Trust, and there have been consistent efforts to maintain and upgrade the property, though some recent construction activities triggered resident complaints about compliance and safety concerns.

Risk rating

How 1722-1726 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

Out of 670 buildings in this neighborhood, 395 are predicted to be safer.
