Initial analysis

The two-unit residential building at 1643 Beach Street, owned by Tyler & Ellen Biggs Rvc In, is a two-story flats and duplex structure built in 1931 in the Marina neighborhood. The building's maintenance history shows several significant structural and safety upgrades, including a 2009 renovation of exterior stairs between the second and third floors, involving the replacement of treads, risers, and stringers at a cost of $2,700, and an earlier structural work completion in 1989. The building's roof received attention in 1996, though that permit is listed as expired.

Recent activity around the property has primarily involved parking-related issues, with multiple complaints and enforcement actions between 2016 and 2023. The most recent incidents in late 2023 involved illegal parking near the property, and there have been recurring problems with driveway blockages, including a citation issued in June 2021. Other local concerns included a 2021 report about waste receptacles being left out continuously, and several requests for color curb modifications between 2016-2017, suggesting ongoing interest in managing parking regulation in the area. While these neighborhood issues are documented as resolved through various enforcement and outreach actions, they indicate an ongoing challenge with parking management and neighborhood compliance that may affect resident convenience and accessibility.

Risk rating

How 1643 Beach 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.
