Initial analysis

The two-unit residential building at 1837-1839 Hayes Street in Park North, owned by Pham Mai Hoang, is a two-story flats and duplex structure built in 1909. The property has undergone several significant renovations and faced multiple compliance issues in recent years. Between 2017-2018, the building underwent substantial improvements including bathroom and kitchen remodels, with permits issued for adding a full bathroom, replacing fixtures, and installing various electrical components including smoke detectors. However, these improvements triggered multiple building violations, particularly a significant complaint filed in December 2017 regarding unauthorized removal of interior stucco to the studs in both units, which resulted in monitoring fees. More recently, as of March 2024, there is an active complaint alleging unpermitted modifications including the addition of 4 skylights, new windows front/rear and lightwells, electric fireplaces, a glass guardrail, entry doors, and garage door modifications, with potential violations of SFBC 103.A and SFBC 110A.

The property's maintenance history shows attention to structural integrity, with earlier records from the 1990s showing dryrot repairs on rear stairs and reroofing work. Recent 311 calls, while not directly related to the building's structural condition, indicate some ongoing neighborhood maintenance concerns, including an open tree maintenance request from July 2023. The building has also experienced some minor issues with unauthorized postings and graffiti on nearby infrastructure, though these are typical of the area and not specific building concerns. The combination of active and past building violations related to unauthorized modifications, particularly the recent complaint about unpermitted work, suggests ongoing compliance monitoring requirements under SFBC regulations, while the extensive renovation work completed between 2017-2018 represents a significant investment in property improvements.

Risk rating

How 1837-1839 Hayes 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.
