Initial analysis

The property at 809-811 Capp Street is a two-story, five-unit multi-family residential building constructed in 1900 and owned by Robert Newdoll. The building has undergone several significant renovations and improvements over the past decade, with the most recent work completed in August 2023 involving dry rot repairs to exterior siding. In 2019, a substantial studio remodel was completed, including kitchen and bath improvements, new electrical work, and window installations, with associated plumbing and electrical permits showing modern HVAC and water heater installations. The building's history reveals several important structural modifications, including a controversial 2011-2012 period where the building's height was reportedly raised by 24 inches without proper permits, leading to violations and requiring subsequent variance applications for compliance.

The property has experienced various maintenance and safety-related issues over the years, including dry rot concerns, stair repairs, and multiple building code violations between 2004-2014. Security and safety improvements were mandated in 2004, requiring new locking devices, self-closing doors, and fire extinguisher maintenance. A significant complaint regarding hazardous wiring and stairwell conditions was filed in 2014, which was subsequently addressed. The building underwent numerous improvements to electrical systems, including complete rewiring of units and upgrades to 200-amp service between 2009-2019, indicating ongoing modernization efforts. Of particular note, there was a period of short-term rental activity at the property that resulted in violations, though these have since been abated according to planning records. The most recent building maintenance work and absence of active violations suggest improved property management and maintenance practices in recent years.

Risk rating

How 809-811 Capp 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 2380 buildings in this neighborhood, 1095 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.

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

Neighborhood location

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

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 48.8%
Moderate concern 24.9%
Severe concern 26.2%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
