Initial analysis

The four-story, 14-unit multi-family residential building at 866 Post Street, owned by Kelamamet LLC, was constructed in 1915 and has undergone several significant structural and safety improvements over its lifetime. Notable historical improvements include seismic retrofit work completed in 1999 (costing $88,000), comprehensive plaster repairs in 1990, and exterior stair repairs in 1987. The building has faced recurring maintenance challenges, particularly with its heating system and boiler permits, experiencing multiple violations between 2015 and 2018 related to unpermitted boiler operation, with corresponding monthly monitoring fees. A recent tenant complaint from December 2022 documented multiple unit issues including exposed electrical wiring, wall cracks, plumbing problems, and window malfunctions, leading to window repair work in early 2023 to address violation #202200323.

More recent concerns have focused on fire safety systems, with violations noted in July 2023 involving extinguishers, alarm systems, and sprinkler/standpipe systems, though these were corrected by September 2023. The building has experienced periodic heating system issues, as evidenced by multiple complaints between 2005 and 2010 regarding inadequate heat, and a notable 2014 complaint related to non-compliance with the mandatory soft-story retrofit program. Recent 311 calls from late 2024 primarily relate to external issues such as garbage, debris, and encampments in the vicinity of the building, rather than internal building conditions. The property has a documented history of fire safety inspections and occasional fire-related responses, though no civilian injuries have been reported in recent incidents.

Risk rating

How 866 Post 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

Out of 448 buildings in this neighborhood, 175 are predicted to be safer.

Model explanation

What's driving this score

The three data points that most influenced this building's risk rating — ranked by the weight the model placed on each one.

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

Building size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

NOV rate, owner's portfolio

Per-building NOV rate across everything this owner manages — high rates signal pattern neglect.

12-Month severity forecast
No violation 12.3%
Moderate concern 64.2%
Severe concern 23.5%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
