Initial analysis

1735-1737 Lyon Street is a three-story, multi-family residential building located in Lower Pacific Heights, consisting of two units and built in 1902. The property underwent substantial renovations between 2014-2015, including a $970,000 project to relocate one unit from the second to first floor, combine second and third floors into a single unit, add roof deck, and perform comprehensive remodels of kitchens, bathrooms, and bedrooms. This renovation period generated several construction-related complaints from neighbors in 2015 regarding issues such as stability concerns, debris management, and potential unauthorized construction work, though all these complaints were marked as not active. During the same renovation period, the building received significant infrastructure upgrades including new fire safety systems (sprinkler installation), complete rewiring of both units, new plumbing systems for comprehensive bathroom and kitchen facilities, and the installation of new gas furnaces.

More recent improvements to the property include the addition of a 4.08 kW solar PV system with battery storage in 2020-2021, and the installation of a hot tub in September 2020. The building's maintenance history shows attention to basic infrastructure needs, including a complete reroofing project in 2014. Notably, a 2022 complaint was filed regarding a possible illegal unit merger involving an open stairway and replacement of a second kitchen with a wet bar, though this complaint appears to have been abated. The property's permit history demonstrates a pattern of significant upgrades and modernization efforts, particularly focusing on safety improvements and eco-friendly enhancements in recent years.

Risk rating

How 1735-1737 Lyon 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
85th percentile

Out of 670 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.

Building size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

Owner's portfolio size

Number of SF parcels this owner is registered on — larger portfolios have distinct risk patterns.

12-Month severity forecast
No violation 70.0%
Moderate concern 18.4%
Severe concern 11.7%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
