Initial analysis

The property at 4034 20th Street is a two-story, three-unit multi-family residential building constructed in 1910, currently owned by Peter and Sheri Harris Revoc. The building has undergone significant recent development activity, most notably a major renovation and expansion project initiated in 2021-2022 that included the installation of a solar PV system (10.4 kW), a new fire sprinkler system throughout the building, and comprehensive electrical upgrades including a new 400-amp service with dual meters. The property is currently in the process of transitioning from a single three-unit structure to a new configuration involving two duplex buildings with basement levels, as part of a lot split project that received conditional approval. This redevelopment plan includes replacing the existing 3-unit structure with two buildings, each containing two residential units, along with associated ADUs, though some permits related to the project have experienced revisions and corrections throughout 2023-2024.

The building's systems have been extensively upgraded through various permitted work, including the installation of new plumbing systems, grey water recycling for laundry systems, and multiple bathroom renovations featuring new shower pans. Recent building permits show ongoing adjustments to window configurations and Title 24 calculations compliance. The property has undergone comprehensive safety upgrades, including a complete fire sprinkler system installation. Multiple 311 calls between 2022 and 2024 have primarily concerned street lighting issues and waste management concerns in the vicinity, though none directly relate to building safety or habitability. Notably, there was one tenant buyout recorded in August 2020 for $114,110, though unit configurations and move-out information for this transaction are not fully detailed in the records provided.

Risk rating

How 4030-4036 20Th 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
62th percentile

Out of 1278 buildings in this neighborhood, 486 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 (past 7 years)

Number of permits pulled at this address — construction or renovation activity over 7 years.

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 61.1%
Moderate concern 33.5%
Severe concern 5.4%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
