Rent & eviction protection

Is 167 21St Ave 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 1965
2 or more units

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

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.

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 167 21st Avenue, owned by the Silverman Rosemary Rev Trust, was constructed in 1965 and contains 6 units. The building has experienced several significant water-related issues over its history, most notably a flood incident in 2015 that affected units 201 and 301, requiring comprehensive repairs to kitchen cabinets, flooring, countertops, and sheetrock, along with associated plumbing and electrical work totaling $20,000. More recently, in 2017, a complaint was filed regarding mold throughout thin walls, following earlier reports of dampness and leaks, including a 2007 complaint about damp carpeting and flooring in a bedroom. The building's maintenance history includes window and door replacements in 2013 (permit expired), and a complete reroofing project in 1992.

In terms of safety and compliance history, the building experienced a cluster of fire safety violations in 2003, including issues with smoke detectors on the third floor and lobby, fire escape ladder maintenance, egress obstructions, and gas utility shutoff tools, though these violations were all abated by June 13, 2003. The property has also had three carbon monoxide-related incidents recorded (two detector activations and one public service call), though no civilian injuries were reported in connection with these events. Other routine inspections have been conducted, including a 2008 inspection, and there was one incident in 1995 involving non-functional appliances and water issues that was quickly resolved. Two recent permits from 2020 (street space) and 2012 (streetlight issue) indicate ongoing attention to building and surrounding area maintenance, though these are not directly related to building habitability issues.

Risk rating

How 167 21St Ave'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
17thpercentile

Out of 660 buildings in this neighborhood, 548 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.

Building size

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

Estimated permit spend (past 7 years)

Dollar value of permits pulled at this address — large recent spend can signal deferred-maintenance catch-up.
