Rent & eviction protection

Is 161-167 Castro 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 before 1979
Built 1900

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 1900
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 four-story, eight-unit multi-family residential building at 161-167 Castro Street in Duboce Triangle, owned by Nelson Thomas Irvine and built in 1900, has undergone several significant renovations and faced various compliance challenges over the years. The most substantial work occurred in 2008-2010, including comprehensive electrical rewiring of all apartments, kitchen and bathroom remodels, and the installation of 4 fireplaces. Building improvements also included foundation sill bolting, though there was one complaint in 2008 about construction work potentially exceeding permitted scope. The property experienced multiple violations in 2001 related to fire safety and code compliance, including issues with smoke detectors and emergency escape ladders, all of which were resolved by November 2001. A notable compliance concern arose in 2014 regarding the mandatory Soft Story Retrofit Program, which was subsequently addressed.

More recent maintenance and safety concerns have been relatively minimal, with the most recent 311 calls primarily related to exterior maintenance issues such as tree overgrowth (opened September 2024), graffiti (resolved September 2023), and general street cleaning (resolved July 2023). The building's mechanical systems have seen some updates, including a tankless water heater installation in 2018, though this permit expired. Historical records indicate regular maintenance and inspections, with the property generally complying with required updates and repairs, particularly regarding fire safety systems and building structure, though some work required multiple permits to properly finalize. The building's maintenance history shows a pattern of addressing violations promptly, particularly during the significant renovation period of 2008-2010 when multiple systems and safety improvements were implemented across all units.

Risk rating

How 161-167 Castro 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
22ndpercentile

Out of 287 buildings in this neighborhood, 224 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.

Number of floors

Building height affects maintenance complexity and is one of the size signals the model uses.

Building age

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