Rent & eviction protection

Is 641 Ofarrell 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.

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 1907
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

641 O'Farrell Street is a 7-story, 97-unit multi-family residential building constructed in 1907, currently owned by 641 O'Farrell Street LLC. The building has undergone significant renovations and faced multiple compliance challenges over the past decade. Major renovation work from 2013 to 2018 included kitchen and bathroom remodels in various units, hallway carpet replacement, and electrical upgrades. In 2016-2017, the building underwent exterior improvements including metal faux brick siding replacement. However, the property has experienced recurring maintenance and safety issues, as evidenced by recent fire code violations in 2024 related to standpipe systems, fire extinguishers, and alarm systems, all requiring corrective action. A notable incident occurred in 2022 when unit 506 suffered significant water damage affecting bathroom/closet areas, with reports of mold and fixture problems. The building also has active complaints regarding boiler permit renewals as of October 2024.

The property has a history of building code violations and complaints from 2009 through 2019, including issues with interior surfaces, maintenance responsiveness, and an intercom system. While many past violations have been abated, including a significant Notice of Violation from 2013 that was addressed by 2018, there are ongoing concerns about fire safety systems based on recent citations. The building underwent various infrastructure improvements in 2019-2019, including electrical system upgrades, but continues to require attention to fire safety compliance as evidenced by multiple violation notifications in 2024.

Risk rating

How 641 Ofarrell 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 172 buildings in this neighborhood, 114 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 16.5%
Moderate concern 60.8%
Severe concern 22.7%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
