Initial analysis

The property at 482-484 Belvedere St is a two-unit, two-story multi-family residential building constructed in 1946, currently owned by Paul & Jennifer Williamson. The building has undergone significant renovations and safety improvements over the past several years, with major work occurring between 2017-2020 including the addition of a partial fourth floor, installation of a complete sprinkler system with 43 heads for both units, and the replacement of four street-facing windows. The building's fire safety system was notably enhanced with the installation of a dedicated 2-inch underground fire water service line costing $13,700, completed in 2020, along with new central heating and cooling systems. Multiple permits required final inspections were processed in 2024, demonstrating ongoing attention to project completion requirements.

The property had one construction-related complaint regarding noise levels in 2017, but this was resolved within two days. Historical records show a sewage backup issue in 2013 that was addressed by PUC Sewer Operations, and minor pavement defect concerns in 2010. The most recent incidents at the property have been primarily related to parking enforcement issues in 2023, including two separate cases of blocked driveways and one case of sidewalk parking, though some cases were invalidated due to incomplete reporting information. The building underwent substantial interior remodeling during 2017-2018, including upgrades to both units' bathrooms, kitchens, and electrical systems, with some permits requiring subsequent renewal and finalization in late 2024. A tenant buyout record from 2016 indicates two tenants received $90,000 under the program, though it's unclear if this affected the current unit configuration.

Risk rating

How 482-484 Belvedere 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
89th percentile

Out of 526 buildings in this neighborhood, 58 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.

Estimated permit spend (past 7 years)

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

Neighborhood location

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

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 86.9%
Moderate concern 9.9%
Severe concern 3.1%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
