Initial analysis

The property at 649-651 Central Avenue in the Park North neighborhood is a two-unit, two-story multi-family residential building constructed in 1900, currently owned by Carl Iii and Maureen Wolfston. The building has undergone significant renovations and maintenance work over recent years, with major improvements completed in 2021 including kitchen and bathroom renovations, furnace replacements, and electrical system upgrades. Multiple building permits have been filed addressing various maintenance issues, including recent work in 2024 to legalize exterior wooden rear stairs and decommission an unpermitted room.

The building has experienced several maintenance challenges and violations over its history, most notably in 2017 when multiple violations were recorded relating to lead paint hazards, water damage, mold, and rodent infestation, though these issues were officially abated by October 2017. More recent concerns include dry rot repairs on the back staircase completed in 2023 and ongoing discussions about the rear wooden stairs conversion from TIC to condominium status. The property underwent significant systems upgrades in 2021-2023, including water heater replacement, plumbing improvements, and electrical work related to a condominium conversion process. While the building has had various maintenance issues over the years, many have been addressed through appropriate permits and repairs, with the most recent permits primarily focusing on compliance and maintenance matters. The area around the property has experienced typical urban challenges as evidenced by multiple 311 calls in late 2024 regarding garbage and debris, though these issues appear to be primarily street-related rather than building-specific.

Risk rating

How 649-651 Central Ave'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.
