Initial analysis

The property at 1650-1656 Post Street is a two-story mixed-use building constructed in 1927, containing 5 residential units and ground-floor retail space, currently owned by K Sakai Company. The building underwent significant redevelopment between 2015-2016, including a major conversion of retail space to a women's spa (Pearl Spa) with associated tenant improvements, addition of 4 residential units (two one-bedroom and two one-bedroom-plus-den), and comprehensive sprinkler system upgrades. The renovation period saw multiple building permits issued, totaling over $250,000 in construction costs, including mechanical, electrical, and plumbing work. Notably, there were several fire code violations recorded between 2018-2023, with specific issues related to blocked exits, door self-closers, and extinguisher maintenance, though most have been abated. The building's fire safety history shows regular alarm activations and false alarms between 2018-2023, with no reported civilian injuries. Recent maintenance issues have included garbage and debris concerns, with the most recent service requests in 2024, though these are not directly related to building safety. The property has maintained active compliance with most building codes, with periodic fire safety inspections resulting in violation notices that appear to have been addressed promptly. Separate complaints about construction debris affecting neighboring properties were recorded in 2016, and there's a recent (2023) fire code violation related to unauthorized work, though specific details on resolution are limited.

Risk rating

How 1650-1656 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
52th percentile

Out of 670 buildings in this neighborhood, 322 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.

Building size

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

Number of units

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

Estimated permit spend (past 7 years)

Dollar value of permits pulled at this address — large recent spend can signal deferred-maintenance catch-up.

12-Month severity forecast
No violation 41.9%
Moderate concern 39.1%
Severe concern 19.0%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
