Initial analysis

The four-unit multi-family residential building at 8 Marion Place in Russian Hill, owned by David S & Maura H Mana 2005, is a four-story structure built in 1917. The property has undergone several significant renovations and maintenance projects over the past decade, including a $45,000 interior remodel in 2017 that involved converting a storage room to a closet, kitchen and bathroom updates, and window replacements. Recent improvements include the replacement of the roof unit with a new 5-ton package unit in late 2022, though a shower valve replacement from 2020 was recorded as expired. Major systems upgrades have been implemented, including a furnace replacement in 2015, gas line installations, and electrical improvements including the installation of a new subpanel and kitchen/bathroom updates in 2017.

The building's history shows several notable incidents, including a significant violation in 2001 related to unauthorized roof HVAC equipment installation that was eventually resolved by 2015. There was also a 2013 complaint regarding exterior paint conditions and potential lead safety concerns, which was addressed by 2014. The most recent concern involves a November 2024 complaint about unpermitted modifications to a retaining wall, though this was abated within a month. The property has maintained active maintenance schedules, with multiple street space permits and various plumbing, electrical, and general building permits showing ongoing upkeep and improvements, including deck repairs in 2016 and multiple kitchen/bathroom renovations. While there have been some parking and street cleaning issues reported through 311 calls near the property, these are typical urban maintenance concerns and not directly related to the building's condition or safety.

Risk rating

How 8 Marion Pl'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 1133 buildings in this neighborhood, 668 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.

Neighborhood location

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

Number of floors

Building height affects maintenance complexity and is one of the size signals the model uses.

12-Month severity forecast
No violation 48.3%
Moderate concern 19.2%
Severe concern 32.6%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
