Initial analysis

The two-unit residential building at 449-451 Ashbury St in the Haight Ashbury neighborhood, built in 1900 and currently owned by Ryan Sakai, has undergone several significant improvements over its history. The most recent major work, filed in April 2023, involves plans to infill under the existing second-floor footprint to create a wet bar serving shared outdoor space and convert the existing roof to a deck, with an estimated cost of $175,000. In prior years, the building has seen substantial upgrades including a complete bathroom renovation in 2014 with new plumbing, framing, skylight, electrical work, and fixtures (cost: $15,000), and a significant electrical upgrade in 2014 that included installing a 200-amp service with three meters for the two units and the house. The property has maintained its infrastructure, with documented work on ductwork replacement in the garage (2015), new furnaces installation (2015), bathroom remodelling (2014), and roof work (2003).

The building has experienced some maintenance issues, including a 2018 complaint about peeling paint, though this case is currently listed as not active. Historical records show a past violation regarding short-term rentals that was resolved in 2017 when the owner's listing was changed to 30-day minimum stays. The property has been the subject of several 311 calls in recent years, primarily relating to exterior issues such as graffiti (2020-2024), general street cleaning needs, and occasional parking enforcement matters. However, these external incidents are more reflective of the neighborhood context than building-specific issues. While there have been various maintenance and improvement projects over the years, the most critical infrastructure work seems to have been addressed through the building's upgrades to electrical service and HVAC systems, with current efforts focused on enhancing shared outdoor spaces.

Risk rating

How 449-451 Ashbury 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
97th percentile

Out of 581 buildings in this neighborhood, 17 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 permits, owner's portfolio

Permits pulled across all of this owner's buildings over 7 years.

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 88.8%
Moderate concern 8.3%
Severe concern 3.0%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
