Rent & eviction protection

Is 2-28 Guerrero 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 1922

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 31-unit, 3-story multi-family residential building at 2-28 Guerrero Street in Mission Dolores, built in 1922, has undergone numerous improvements and faced several challenges over recent years. The most significant current concern is an active complaint from December 2024 regarding water leakage from the roof affecting electric panel areas, with previous repairs left incomplete. In 2023, the building received a sleeping area requirement violation that is currently open and requires permit correction. The building has seen substantial unit upgrades between 2019-2024, including kitchen and bathroom remodels in multiple units (102, 208, 300, 106, 107, 103, 104, and 305), a comprehensive fire alarm system installation in 2020, and most recently, the conversion of a ground floor retail space to a hair studio in 2024.

Historical issues include several violations from 2004-2010 regarding boiler permits, unauthorized construction, and expired permits, though these were ultimately abated. A notable incident occurred in 2021 involving structural concerns between units 207 and 307, though this was marked as not active soon after filing. The building has experienced recurring maintenance challenges, with complaints about mailbox security (2017), mold issues (2011), and plumbing work (2010) all requiring attention. While the property has maintained active fire safety systems with occasional violations being addressed promptly, the recent roof and electrical panel water leakage issues, along with the open sleeping area violation from 2023, are areas of current concern that require monitoring.

Risk rating

How 2-28 Guerrero 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
1stpercentile

Out of 799 buildings in this neighborhood, 791 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.

Building size

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

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

NOV rate, owner's portfolio

Per-building NOV rate across everything this owner manages — high rates signal pattern neglect.
