Initial analysis

The 25-unit multi-family residential building at 400-426 Page Street, owned by SF Multifamily IV Property, was constructed in 1928 and has undergone significant renovations in recent years. Most notably, a major permit filed in October 2020 proposes adding six ground-level units by converting the existing garage, though this remains in filed status as of now. The building has seen extensive unit improvements between 2018-2020, including conversions from studios to one-bedroom units in multiple apartments (notably units 102, 205, 303, and 306), with comprehensive renovations including new kitchens, bathrooms, and in-unit laundry facilities. Infrastructure updates include a new high-efficiency water heater installation in June 2023, electrical panel upgrades, and compliance with various safety upgrades.

Recent concerns include a November 2023 complaint about sagging windows in the bay window and windows above the garage, as well as an active August 2023 complaint regarding common areas. Historical issues from earlier years show attention to safety and maintenance matters, including fire escape maintenance, boiler permits, and window repairs, all of which were addressed and abated. The building has experienced several minor fire-related incidents over the years, including cooking fires and alarm system activations, though none resulted in civilian injuries and all were promptly addressed. The property has completed its mandatory soft-story seismic retrofit (Tier 2) requirements. Recent 311 calls predominantly relate to parking enforcement and street cleaning issues rather than building maintenance concerns.

Risk rating

How 400-426 Page 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
2th percentile

Out of 1027 buildings in this neighborhood, 1006 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 size

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

Number of units

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

NOV rate, owner's portfolio

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

12-Month severity forecast
No violation 8.8%
Moderate concern 84.6%
Severe concern 6.6%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
