Rent & eviction protection

Is 2017-2021 23Rd 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 1907

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 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

The 3-unit residential building at 2017-2021 23rd Street in Potrero Hill, owned by Anastacios G Chilicas Revoc, has undergone several significant maintenance and compliance issues since its construction in 1907. Most recently, in August 2024, the property required both stair repairs and sewer lateral replacement. The building has faced persistent exterior maintenance challenges, particularly regarding lead paint concerns, with multiple complaints from 2019 through 2023 documenting issues of peeling paint and weatherproofing problems. A series of violations were issued in November 2023 relating to improper work practices and safety concerns during what appeared to be unauthorized construction work, though these violations were abated by April 2024.

Historical records show the building has had various structural and safety concerns over the years, including water damage and dry rot repairs in 1998, a 125-amp electrical service upgrade in 2003, and multiple expired renovation permits from the late 1990s. The property has been the subject of numerous housing inspection complaints, with notable issues in 2009 regarding lack of heat, electrical problems, and pest infestations in one unit. The building also experienced three fire-related complaints between 2005 and 2020, primarily regarding combustible materials, though most were found to have no merit or resulted from access issues. While recent permits suggest ongoing maintenance attention, including the approved replacement of rear stairs as a required second means of egress, the building's historical record indicates a pattern of deferred maintenance and compliance issues requiring intervention from various city departments.

Risk rating

How 2017-2021 23Rd 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
3rdpercentile

Out of 726 buildings in this neighborhood, 704 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.

DBI tenant complaints (past 7 years)

Formal complaints tenants filed with DBI about this building over 7 years.

Neighborhood location

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

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.
