Initial analysis

The property at 3536 21st Street is a two-unit, two-story multi-family residential building built in 1904, currently registered under the Stephen & Deborah Family Trust. The building's maintenance history reveals recurring issues with water damage and rot, particularly in exterior areas, with multiple repair projects documented between 1990 and 2012. Most notably, there were significant repairs to the front bay, deck, and porch structure in 2011-2012, while earlier work included termite remediation in 1990 and various remodeling projects in the 1990s and early 2000s, including bathroom renovations, electrical system upgrades, and reroofing. The most recent major building permit on record dates back to 2012 for siding repairs, which suggests the property may be due for some exterior maintenance given the more than decade-long gap since the last recorded structural work.

The property and its immediate vicinity have experienced various municipal service issues in recent years, with multiple 311 calls in 2024 concerning maintenance matters. These include open complaints regarding construction-related signage and maintenance/repair issues affecting Muni services, along with several tree-related incidents including a fallen tree and other maintenance concerns. There were also two street cleaning complaints in November 2024 related to garbage and debris, though these were resolved. While these recent municipal service calls primarily relate to external factors rather than the building itself, they indicate ongoing maintenance and environmental challenges in the immediate area.

Risk rating

How 3536 21St 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

Out of 1278 buildings in this neighborhood, 498 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.

Neighborhood location

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

Neighborhood (ZIP code)

The ZIP code captures local housing market and enforcement patterns that affect all buildings in the area.

Building age

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

12-Month severity forecast
No violation 74.8%
Moderate concern 12.4%
Severe concern 12.9%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
