Rent & eviction protection

Is 180 Blake 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 1975

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 1975
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 two-story, five-unit apartment building at 180 Blake Street in the Lone Mountain neighborhood, owned by Jang 2004 Trust, was constructed in 1975 and has undergone several significant modifications throughout its history. Most notably, the building completed a seismic retrofit in 2017 at a cost of $36,000, bringing it into compliance with current safety standards (Tier 3 soft-story status: Work Complete, CFC Issued). The building's permit history shows various other improvements, including a reroofing project in 2009 ($13,500), the creation of a stairway in 1989, and efforts to legalize unit configurations in the mid-1980s, though some permits from that era expired or were cancelled.

The property has undergone two routine housing inspections (1999 and 2004), both of which were resolved promptly. While there have been numerous 311 complaints in the vicinity since 2022, most have been related to street conditions, parking issues, or general urban maintenance rather than building-specific concerns. The most recent building-related permits and inspections suggest that major structural and safety systems have been properly maintained, with no significant building-specific complaints or violations on record in recent years. The property appears to be in good standing with respect to major safety and maintenance requirements, with all recent permits having been properly completed and closed.

Risk rating

How 180 Blake 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
42ndpercentile

Out of 519 buildings in this neighborhood, 301 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.
