Initial analysis

The two-story, four-unit multi-family residential building at 573-577 Frederick Street, owned by Mike R Chang, was constructed in 1908 and has undergone several significant maintenance and operational changes over its history. The building has experienced two fire-related incidents since 2003, both involving detector or alarm system activations with no actual fire or injuries reported. A notable cluster of fire safety violations occurred in 2003 and 2008, including issues with fire proofing materials, fire extinguisher requirements, and combustible storage concerns, though all these violations were subsequently abated. Recent maintenance includes a 2022 permit application for intermediate length occupancy in Unit A, which is currently in filed status, and a series of street cleaning and maintenance requests in 2022-2024 that have been resolved. A significant repair project was completed in 2000 involving repairs to the rear base, concrete wall, lower deck, ground level stairs, and rear siding door at a cost of $6,000. The building's maintenance history shows attention to basic upkeep, including a complete reroofing project in 2001 costing $8,500.

The most recent building complaint was filed in December 2015, concerning gaps between windows and leaks in the utility room ceiling, while routine housing inspections occurred in 2003 and 2008. The property has generated multiple 311 calls in recent years, mostly relating to street cleaning and sidewalk maintenance matters, with the most recent being from October 2024 regarding illegal parking, though recent fire safety violations show no current activity impacting resident safety. The building maintains a relatively stable record since the 2008-2015 period, with no active building violations or major safety concerns noted in recent years, though the status of the 2022 intermediate length occupancy permit remains pending.

Risk rating

How 573-577 Frederick 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
32th percentile

Out of 526 buildings in this neighborhood, 358 are predicted to be safer.

Model explanation

What's driving this score

Number of units

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

Estimated permit spend (past 7 years)

Dollar value of permits pulled at this address — large recent spend can signal deferred-maintenance catch-up.

Owner's portfolio size

Number of SF parcels this owner is registered on — larger portfolios have distinct risk patterns.

12-Month severity forecast
No violation 70.1%
Moderate concern 16.8%
Severe concern 13.1%
