Initial analysis

The 6-unit residential building at 535-543 Ashbury Street in Haight Ashbury, owned by Richard M. Dudum and Randa M. Dudum, has undergone several significant renovations and faced various maintenance challenges since its construction in 1905. Most recently, in August 2023, Unit #5 received a $75,000 renovation including kitchen upgrades, electrical work, and plumbing improvements. The building has seen multiple electrical system upgrades, including a comprehensive fire alarm system installation in 2018 and several circuit additions in 2021. Major maintenance work in 2010 involved structural repairs to the rear building including replacement of posts, beams, and footings. The property has experienced several plumbing issues, notably a main sewer line repair in 2013 and significant work in 2010 addressing leaks in units #1 and #3, as well as stairwell plumbing problems.

The building has undergone routine inspections revealing various maintenance needs, including a 2010 violation for defective kitchen waste piping and a wall heater installation issue, both of which were subsequently resolved. Recent complaints from 2024 regarding scraping and sanding work have raised concerns about debris containment and worker safety at the site. The building's safety systems were notably updated in 2018 with the installation of new fire alarm equipment and low-frequency horns. Historical works include a complete reroofing in 2003 and various kitchen upgrades in multiple units, particularly Units #1 and #3, which have received significant renovations over the years. The property has maintained active compliance with most building codes, with only minor routine violations occurring, though recent complaints suggest ongoing attention to construction practices is necessary. A 424 carbon monoxide incident was recorded, though no civilian injuries were reported. The surrounding area has seen various municipal service calls in 2024, including sidewalk repairs, encampment removal, and public health concerns, though these are not directly related to the building's condition or management.

Risk rating

How 535-543 Ashbury 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

61th percentile

Out of 581 buildings in this neighborhood, 227 are predicted to be safer.
