Rent & eviction protection

Is 4082-4086 23Rd 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.

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

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 property at 4082-4086 23rd Street is a two-unit, two-story residential building constructed in 1882 in San Francisco's Noe Valley neighborhood. The building has a documented history of structural issues, particularly concerning dry rot, with multiple repair permits issued between 1999 and 2001 totaling significant costs (starting from $40,000 up to $60,000). During this renovation period, serious concerns emerged in 2000 when a building violation was filed regarding expired permits, inadequate security at the construction site, and exceeding the scope of permits by gutting the structure. This period also saw issues with a caved-in ceiling reported in late 1998 (though this complaint was quickly abated) and electrical work done without proper permits in late 2001.

More recently, the property has faced recurring issues with tree maintenance, particularly concerning lifted sidewalk tree roots, with multiple reports filed between September 2023 and February 2024. A collapsed sidewalk issue was reported and resolved in August 2023. The building's historical permits show various improvements over the years, including window replacements, kitchen and bathroom renovations, furnace replacements, and later repairs to stairs and decks. The most recent significant tree-related issues, which appear to be ongoing as of 2023-2024, suggest continuing challenges with the property's external environment, particularly regarding sidewalk damage and tree maintenance, though these are generally municipal infrastructure issues rather than building structural concerns.

Risk rating

How 4082-4086 23Rd 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
95thpercentile

Out of 1879 buildings in this neighborhood, 94 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
