Initial analysis

The property located at 4391-4399 24th Street in Noe Valley is a 6-unit, 2-story multi-family residential building constructed in 1913, currently owned by Phillip Adam & Christine. The building has undergone significant renovations and improvements over the past several years, with the most recent work being a re-roofing project completed in 2024 costing $23,100, and the replacement of a 40-gallon water heater in March 2024. A major interior renovation project was filed in late 2021 to remodel the second floor and attic, including the addition of roof dormers, though this permit was still in "Filed" status as of the last review. Between 2018 and 2021, substantial updates were made including electrical upgrades (200A service upgrade in 2021), multiple bathroom and kitchen renovations, installation of new laundry facilities, and various safety improvements such as smoke detector installations and rewiring of units. The building has had some maintenance issues in the past, including reports of water shutoffs during renovations in 2018, though these complaints were marked as not active. Earlier complaints from the 1990s related to heating system problems and lead paint issues, but these appear to have been resolved long ago.

The property has maintained active upkeep through various system upgrades, including multiple water heater and HVAC system replacements, and has received attention to both common areas and individual units. Recent permits indicate ongoing improvements, with the most current registered permit as of October 2024 for the installation of a transfer switch. The building's maintenance history shows a pattern of regular updates to keep systems modern and address any structural or comfort-related issues, with no current active building complaints on record. The most significant recent structural change appears to be the planned attic conversion and dormer additions, which would represent a substantial enhancement to the building's usable space if completed.

Risk rating

How 4391-4399 24Th 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.

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.

Building size

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

Estimated permit spend (past 7 years)

Dollar value of permits pulled at this address — large recent spend can signal deferred-maintenance catch-up.

12-Month severity forecast
No violation 61.0%
Moderate concern 23.5%
Severe concern 15.5%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
