Rent & eviction protection

Is 647-651 Fell 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 1908

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.

Built 1908
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 three-story multi-family residential building at 647-651 Fell Street in Hayes Valley, owned by Kockos Kent, was constructed in 1908 and contains 6 units. The building has undergone several significant safety and infrastructure improvements over the past few decades, most notably completing required soft-story seismic retrofitting in 2017 at a cost of $50,000, and addressing reroofing needs in 2000 for $6,480. Multiple safety concerns were documented in 2003 and 2008, including gas meter safety requirements, fire safety issues, and security improvements, all of which were subsequently addressed and closed out. A major incident occurred in March 2019 involving collapsed temporary structures with unsecured materials, though this complaint was later marked as not active. More recent building maintenance issues include a water leak complaint in 2017 and several sidewalk cleaning incidents between 2019-2023, primarily involving waste and hazardous materials, which were all resolved. The property has maintained compliance with current safety regulations, as evidenced by the completed work and issuance of Certificate of Final Completion (CFC) for the soft-story retrofit program under Tier 3 status.

The building's historical maintenance record shows attention to compliance with safety requirements, particularly fire safety and seismic retrofitting, which suggests an ongoing commitment to maintaining structural integrity and resident safety. While there have been various complaints and violations over the years, virtually all have been addressed and resolved, with no active violations on record as of the most recent data. The property has also experienced typical urban challenges as noted in 311 calls, primarily related to street and sidewalk maintenance, though these issues appear to be external to the building itself and have been consistently resolved by appropriate city agencies.

Risk rating

How 647-651 Fell 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

Lower risk — safer than most nearby

DBI rarely finds violations here. Strong maintenance history and a clean complaint record.

Typical — about average for the neighborhood

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Higher risk — riskier than most nearby

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.

Neighborhood percentile
43rdpercentile

Out of 1027 buildings in this neighborhood, 585 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.

Neighborhood (ZIP code)

The ZIP code captures local housing market and enforcement patterns that affect all buildings in the area.

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.
