Initial analysis

The five-unit, two-story apartment building at 1721 Clement Street in the Central Richmond neighborhood, owned by Lew Living Trust The, has undergone several significant improvements and faced notable challenges since its construction in 1962. Most recently, in 2021, the building underwent a mandatory fire alarm system replacement to comply with California state fire safety requirements, though this work was noted to not fully meet current building fire codes or NFPA 72 standards. The building experienced a substantial fire-related incident in 2015, requiring approximately $50,000 in repairs including smoke damage remediation in multiple units (particularly affecting Unit #2), and subsequent replacement of fire-damaged electrical systems and plumbing components. Several other maintenance and improvement projects have been completed over the years, including window replacements in 2018 (upgrading from aluminum to fiberglass), exterior stair landing repairs in 2016, and historical work such as reroofing and siding repairs in 1994.

The property has a relatively clean inspection record, with only one notable building violation in 2003 regarding the central alarm system that was promptly resolved. A recent tenant complaint from October 2022 involved disputes over floor damage charges during a move-out inspection, though this matter is no longer active. The building's common areas and systems have generally been maintained, with the most recent major upgrade being the 2021 fire alarm system improvement. The property has generated numerous parking-related service requests in recent years (2023-2024), primarily concerning blocked driveways and illegal parking, though many of these were handled through regular enforcement channels and do not directly reflect on the building's condition or management.

Risk rating

How 1721 Clement 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 2250 buildings in this neighborhood, 1845 are predicted to be safer.

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.

DBI tenant complaints (past 7 years)

Formal complaints tenants filed with DBI about this building over 7 years.

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.

12-Month severity forecast
No violation 71.4%
Moderate concern 22.8%
Severe concern 5.7%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
