Rent & eviction protection

Is 550 Stockton St rent-controlled?

San Francisco's Rent Ordinance caps rent increases and provides eviction protection for most residential units built before 1979 with 2+ units. Here's how this building scores.

Built before 1979
Built 1923
2 or more units

Likely rent-controlled. Building age and unit count suggest this property falls under San Francisco's Rent Ordinance.

Based on SF Assessor records. Not legal advice — confirm with the SF Rent Board.

Statewide backstop · AB 1482

California Tenant Protection Act of 2019

Even when a building isn't covered by local rent stabilization, the statewide Tenant Protection Act (AB 1482) may still apply. It caps annual rent increases and requires the landlord to state a legal reason to end most tenancies.

15+ years since occupancy
Built 1923
Annual rent increase cap
5% + CPI, max 10%
Just-cause eviction
After 12 months
Local rent control likely takes priority. This building appears to fall under the local ordinance above, which is stronger than AB 1482. Where a local just-cause ordinance applies, its rules govern instead of the state cap.

AB 1482 does not apply to single-family homes and condos unless owned by a corporation, REIT, or an LLC with a corporate member; to owner-occupied duplexes; or to deed-restricted affordable housing. The Act is in effect until January 1, 2030. Not legal advice — see the California landlord–tenant guide.

Initial analysis

The four-story, 21-unit residential building at 550 Stockton Street in the Financial District North, owned by Farley & Cecile Lee 2003 Fm, has experienced several significant maintenance and safety issues in recent years. Most notably, in 2025, there were serious plumbing problems including multiple leaks affecting multiple units, resulting in mold growth, including reported instances of a mushroom growing in a kitchen area. There were also concerning electrical issues in early 2025, with reports of a dangerous makeshift electrical connection using metal bars in the breaker box. More recently, in April 2024, the building received multiple Notices of Violation requiring attention to various safety systems, including repairs to a damaged garage ceiling, updates to fire escape systems, and compliance with smoke/carbon monoxide alarm requirements. These violations indicated the building was considered a nuisance under San Francisco Housing Code Section 1001-d.

The building's fire safety systems have received attention in recent years, with two completes fire alarm system upgrades between 2022 and 2023 that included new smoke detectors, pull stations, and other safety improvements at a cost of $20,000. The property has generated 80 service requests through 311 over the past seven years, though most appear to be related to non-building maintenance issues such as illegal parking and garbage. The building's documented history shows a pattern of delayed maintenance response, particularly regarding water damage and plumbing issues, with several complaints about inadequate repairs and resulting conditions such as mold and odors. However, it's worth noting that from mid-2025 through October 2023, there have been no recorded fire incidents.

Risk rating

How 550 Stockton 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 145 buildings in this neighborhood, 113 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.

Building size

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

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 13.7%
Moderate concern 68.1%
Severe concern 18.2%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
