Initial analysis

The three-unit residential building at 4040-4044 18th Street, owned by Zanco Trust The, has undergone significant renovations and faced several permit-related issues in recent years. Built in 1906, this three-story flats and duplex structure has been the subject of extensive remodeling work throughout 2023-2024, including kitchen and bathroom renovations, the addition of new bathrooms, laundry facilities, and HVAC system upgrades. The most recent completed work in January 2024 involved substantial improvements to unit 4044, and earlier in 2023, critical repairs were made to address dry rot in the rear wall and windows. A notable concern emerged in October 2023, when complaints were filed regarding unauthorized construction and expired permits related to a fourth floor expansion, which remains an active violation as of this date.

The building has a history of maintenance and safety issues that required attention, including past violations for garbage receptacle placement, handrail deficiencies, broken windows, security concerns, and roof-related problems, all of which were abated by 2003. More recent concerns from 2013 involved water leakage, chipping paint, and potential lead hazards, though these were resolved by October 2013. The property underwent significant structural improvements in 2022 with the replacement of brick foundations, and multiple unit upgrades were performed throughout 2023-2024 including bathroom and kitchen remodels, electrical updates, and plumbing improvements. The building's administrative history includes two documented tenant buyouts: one in early 2024 for unit 4044 at $180,000, and another in 2022 for unit 4042 at $65,000.

Risk rating

How 4040-4044 18Th 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
17th percentile

Out of 1278 buildings in this neighborhood, 1061 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.

NOV rate, owner's portfolio

Per-building NOV rate across everything this owner manages — high rates signal pattern neglect.

DBI tenant complaints (past 7 years)

Formal complaints tenants filed with DBI about this building 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 60.0%
Moderate concern 32.5%
Severe concern 7.4%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
