Initial analysis

The property at 77-79 Parnassus Ave is a two-unit, two-story multi-family residential building constructed in 1906, currently owned by Paul A & Faina R Disterheft. The building has undergone several significant improvements and maintenance work over the years, including a major renovation in 2006 that involved kitchen and bathroom remodeling in the lower flat, window installation, structural modifications, and the addition of solar panels. More recently, there has been substantial activity, with a filed permit in 2021 for converting the basement into a 1-bedroom ADU with an addition and deck, valued at $230,000. The building's systems have been regularly updated, including furnace replacements in 2015, sewer lateral repairs in 2024, water heater replacement in 2024, and electrical system upgrades including solar panel installation in 2012-2015.

Recent concerns include a complaint filed in September 2024 regarding inadequate containment during ongoing work, and permit records suggest the building is currently in the midst of significant construction activity. The property has experienced recurring issues with parking violations, particularly regarding driveway blocking, with multiple documented incidents between 2019 and 2024. Graffiti incidents were reported in 2020-2022, although these appear to have been resolved. The building's maintenance record shows regular upkeep of major systems, including roofing work in 2010, flooring repairs, and various plumbing upgrades, suggesting active management of the property's infrastructure. A recent 311 call regarding garbage and debris was closed as "No Work Needed," indicating limited impact on resident conditions. The property's historical records and recent permits indicate significant investment in modernization and compliance with current housing standards, though the recent construction complaint and ongoing ADU conversion work are notable points of attention.

Risk rating

How 77-79 Parnassus Ave'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
81th percentile

Out of 526 buildings in this neighborhood, 100 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 age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.

Estimated permit spend (past 7 years)

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

Property class: multi-family flat

2–4 unit flats (class F) are a common SF building type with their own maintenance and complaint patterns.

12-Month severity forecast
No violation 77.6%
Moderate concern 15.3%
Severe concern 7.1%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
