Initial analysis

The three-story multi-family residential building at 3821 Jackson Street in Presidio Heights, owned by Gregory & Julie Flynn since 2002, has undergone significant renovations and maintenance since its construction in 1905. Most recently, in early 2024, the property completed bathroom remodeling work costing $75,000, following a kitchen remodel in mid-2023 valued at $85,000, both involving updates to fixtures and finishes without major structural changes. The building has seen substantial infrastructure improvements, including a major sewer line replacement in late 2019 (including approximately 70 linear feet of excavation and shoring work) and electrical system upgrades such as a 60-amp subpanel installation in 2019. Structural modifications were performed in 2017 with the removal of attic posts and subsequent revisions to support systems. The property experienced one significant building complaint in late 2019 regarding a trench excavation, though this was eventually resolved by early 2024.

The building has maintained regular upkeep through various permits for roofing (2017), multiple bathroom renovations (2004, 2024), and comprehensive plumbing work including sewer line repairs and fixture updates. Historical records show consistent maintenance of building systems, including electrical upgrades and a significant underground service conversion to 200-amp service in 2005. While there have been several 311 calls related to the property's vicinity (including sewer issues in 2014 and sidewalk defects in 2015), these were generally systemic neighborhood concerns rather than building-specific problems. The property is currently up to date with all major systems and has undergone multiple interior improvements that enhance resident comfort while preserving the building's historic character.

Risk rating

How 3821 Jackson 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
98th percentile

Out of 181 buildings in this neighborhood, 4 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.

Building age

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

DBI tenant complaints (past 7 years)

Formal complaints tenants filed with DBI about this building over 7 years.

12-Month severity forecast
No violation 81.0%
Moderate concern 16.8%
Severe concern 2.2%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
