Rent & eviction protection

Is 573-575 Naples 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 1902
2 or more units

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

Based on SF Assessor records. Not legal advice — confirm with the SF Rent Board.

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 1902
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-unit residential building at 573-575 Naples Street in the Excelsior neighborhood, currently owned by 573-575 Naples St LLC, has a significant history of fire-related incidents and renovations since its construction in 1902. The most critical event occurred in February 2021, when a fire incident led to active violations that require monthly monitoring fees. Subsequently, in August 2021, extensive repairs were undertaken to address fire and smoke damage, including electrical rewiring, plumbing updates, and fixture replacements, with associated costs of $350,000. The building underwent additional modifications in 2022, including legalized unit modifications and the removal of unpermitted third-floor portions, as well as re-roofing works. A horizontal addition was previously completed in 2002 at a cost of $160,000, and in 2005, a new bathroom was added to the first floor.

The property has experienced several maintenance and compliance challenges, including complaints about construction debris in 2022, work being performed without proper permits in 2021, and ongoing parking and sanitation issues in the vicinity as evidenced by multiple 311 calls from 2024 to 2025. A 2015 fire inspection related to combustible materials was found to have "no merit." The building's history also includes efforts to resolve unit legalization matters, with a successful completion of unit B legalization in 2015. More recently, there have been multiple reports of garbage and debris issues on the property, primarily consisting of furniture, with the most recent incidents occurring in January 2025.

Risk rating

How 573-575 Naples 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
25thpercentile

Out of 337 buildings in this neighborhood, 253 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
