Rent & eviction protection

Is 3648 26Th 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 1967
2 or more units

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 1967
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 4-unit, 2-story multi-family residential building at 3648 26th Street in Noe Valley, owned by Bent & Angela Sozzi Kjolby and constructed in 1967, has undergone several significant maintenance and safety-related interventions over the years. Recent building improvements include deck and stucco repairs in 2012 ($15,000) and reroofing projects in 2010 ($5,500), following an earlier attempt in 1995 that expired. The building has undergone three routine housing inspections (2001, 2009, 2016) which revealed multiple safety concerns that were subsequently addressed, including fire safety violations related to fire extinguisher maintenance and egress obstructions, as well as water damage repairs. All these violations were officially abated by August 23, 2001.

The property has had recurring issues with vehicle parking violations, particularly concerning blocked driveways, with multiple citations issued between 2021 and 2024, though some reports resulted in officers being unable to locate the offending vehicles. Recent neighborhood service calls from 2021-2024 primarily relate to street cleaning and debris removal, with the most recent incidents involving reports of human waste or urine (December 2024, July 2024). While these exterior issues don't directly impact building safety, they may affect the general environment around the property. The building's permit and violation history suggests that while past safety concerns have been resolved, the property requires continued attention to maintenance and compliance with housing codes. The most recent reported safety inspections and resolved violations indicate a period of compliance from 2016 onward, with no recorded violations or complaints in recent years pertaining to building safety systems, though routine maintenance continues to be necessary as evidenced by historical repair records.

Risk rating

How 3648 26Th 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
45thpercentile

Out of 1879 buildings in this neighborhood, 1033 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.

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.

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.

Neighborhood (ZIP code)

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