Initial analysis

The 18-unit, 3-story multi-family residential building at 1690 Bay Street in the Marina neighborhood, owned by Isac & Eileen C Marchasin R, was constructed in 1931 and has undergone several significant updates in recent years. Most notably, the building has been actively addressing fire safety concerns, with a pending fire alarm system upgrade (costing $58,855) to comply with SFFD requirements, new wall heaters installation, and electrical system improvements including replacing 16 Federal Pacific panels with Murray/Siemens breakers in 2020. The property has experienced multiple building violations in 2023-2024, primarily related to fire safety and electrical systems, including issues with kitchen outlets, heating systems, and smoke/fire doors, though all these violations were officially abated by June 14, 2024. Historical improvements include window replacements in 2011 and several structural and utility updates between 1989-1997.

The building has a documented history of fire alarm system maintenance issues, with violations and complaints related to alarm systems between 2008 and 2024, though these were typically corrected promptly. Recent compliance efforts include the installation of a 220V wall heater in January 2025 and various electrical repairs in 2024, suggesting ongoing maintenance and upgrading of building systems. The property's fire incidents record shows primarily false alarms and detector malfunctions with no civilian injuries reported. Recent 311 calls from 2023-2024 indicate typical urban issues in the vicinity, such as parking violations and sidewalk blockage, but these are not directly related to building conditions or safety. The most recent fire violation regarding sleeping area requirements from January 2024 has been referred to hearing, indicating ongoing regulatory scrutiny of fire safety compliance.

Risk rating

How 1690 Bay 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
