Initial analysis

The 40-unit multi-family residential building at 1050 Post Street, owned by SF 1050 Post Street LLC, is a 4-story apartment building constructed in 1911 in the Downtown neighborhood. The building has undergone significant recent improvements, with multiple unit renovations between 2020 and 2023, including kitchen and bathroom remodels in Units 26, 28, 36, and 47, as well as the installation of washer/dryer facilities in several units. Major building system upgrades have been implemented, including a comprehensive fire alarm system upgrade in 2022 to meet safety codes, replacement of smoke detection and notification devices, and significant plumbing work including sewer stack replacement in 2018.

However, the building currently has active violations filed in December 2024 regarding damaged ceilings, walls, and general dilapidation. Previous resident concerns documented in 2024 include significant pest problems (insects/rodents) and ongoing maintenance issues such as elevator reliability, which has been a recurring problem documented in multiple complaints from 2017 to 2019. There have been several fire safety violations and complaints between 2007 and 2024, including concerns about sprinkler systems, alarm systems, and smoke detector maintenance, though many of these have been subsequently abated. The building has experienced various maintenance challenges over the years, including water issues affecting multiple floors (notably in 2019), though recent renovation activity suggests substantial ongoing investment in building improvements. The property has also generated numerous 311 calls in late 2024 related to debris and garbage management in the surrounding area, indicating possible ongoing maintenance and sanitation challenges.

Risk rating

How 1050 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
39th percentile

Out of 448 buildings in this neighborhood, 273 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.

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.

12-Month severity forecast
No violation 4.6%
Moderate concern 90.8%
Severe concern 4.6%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
