Initial analysis

The two-unit residential building at 55-57 Delmar Street in Haight Ashbury, owned by Scott Mayfield Separate Pro, is a two-story flats and duplex structure built in 1905. The property has undergone several significant renovations and maintenance work over the years, with the most recent being a substantial reroofing project in October 2023 costing $33,995. Major internal modifications were carried out in the mid-2000s, including the demolition of a bearing wall to open up living space, with associated structural reinforcements - initially permitted in 2006 and completed in 2008. The building's systems have seen upgrades as well, with a sewer plumbing permit completed in 2014, and electrical work related to lighting fixtures and switches in 2021.

Recent tenant activity includes a buyout of three tenants at 55 Delmar Street in August 2021 for $60,000. The property has had consistent maintenance and improvement work throughout its history, with various permits issued for different types of work, including residential and non-residential electrical installations, and bathroom modifications. A notable pattern has emerged recently regarding parking enforcement issues, with ten documented cases of driveway blocking between September 2024 and December 2024, resulting in several citations being issued, though some cases were unable to be located by enforcement officers.

Risk rating

How 55-57 Delmar 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
82th percentile

Out of 581 buildings in this neighborhood, 105 are predicted to be safer.
