Initial analysis

The 444-446 4th Avenue property in San Francisco's Inner Richmond district is a two-story, multi-family residential building constructed in 1905, currently owned by Mary A. Lafrenz. The building has undergone significant recent renovations throughout 2024, including comprehensive kitchen and bathroom remodels on both ground and second floors, installation of new plumbing systems, electrical rewiring, and the addition of a dormer. Permits show substantial work completed or in progress, including the relocation of walls, bathroom conversions, and furnace replacements, with multiple electrical improvements such as 200-amp service upgrades and extensive outlet/lighting installations. Historical records indicate some past concerns, including a 2006 complaint about an unauthorized in-law unit in the ground floor, which was abated in fall 2006, and a 2016 complaint regarding drainage issues with neighboring properties. The building's infrastructure has been actively maintained, with earlier improvements including roof replacement in 2008, and various plumbing and electrical upgrades in 2014.

The property's maintenance history shows regular upkeep and modernization efforts, particularly in 2024, with multiple permits issued for substantial improvements across both units. These improvements include the installation of new bathrooms, kitchen remodels, electrical system upgrades, and plumbing system overhauls. While there have been some building complaints over the years, including sewer issues in 2012 and a construction noise complaint in 2018, these were not directly related to ongoing building conditions. The most recent fire complaint from December 2023 regarding shared spaces was determined to have no merit as of March 2024. The extensive renovations currently underway suggest proactive maintenance of the building's systems and living spaces, though potential tenants should note that some construction work may still be in progress based on the most recent issued permits.

Risk rating

How 444-446 4Th 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.
