Nothing on record for this building in the last seven years. Our model still sees a moderate chance of maintenance problems in the next 12 months, from the owner's wider portfolio and the surrounding area rather than from anything recorded here. No public enforcement record to go on. Walk the building, ask the current tenants how repairs get handled, and get any promises in writing.

Rent & eviction protection

Is 3533-3535 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.

Built before 1979
Built 1900
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 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 3533-3535 23rd Street property is a two-story multi-family residential building located in Noe Valley, containing three units and owned by Antonio Mezquiriz. Built in 1900, this flats and duplex-style building has undergone several significant repairs and improvements over the past two decades. Most recently, in August 2024, electric vehicle chargers were installed for unit 2 and unit 4, demonstrating modernization efforts by the current ownership. The building's history shows a pattern of maintenance and compliance work, particularly in the early 2000s, when multiple permits were issued and violations addressed, including kitchen remodeling in 2001, window repairs in 2006, and significant work in response to a 2001 routine apartment house inspection that identified multiple issues such as deteriorated drainage pipes, stair repairs, and safety concerns. These violations were ultimately resolved by November 2004.

The property has had several permitted construction projects, including kitchen remodeling in 2001 (though multiple permits for this work expired), stair repairs in 2002 (which generated a notice of violation), and window casing repairs in 2006. The building's maintenance record shows attention to both code compliance and modernization, as evidenced by the recent EV charger installation. The surrounding area has experienced typical urban issues as documented in 311 calls, though these are not directly related to the building's condition or management. Recent municipal services have responded to various sidewalk and street maintenance issues near the property, including a 2023 pavement defect report and parking concerns, but these external matters do not reflect on the building's internal conditions or management.

Risk rating

How 3533-3535 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
30thpercentile

Out of 1879 buildings in this neighborhood, 1315 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.

Neighborhood (ZIP code)

The ZIP code captures local housing market and enforcement patterns that affect all buildings in the area.

Estimated permit spend (past 7 years)

Dollar value of permits pulled at this address — large recent spend can signal deferred-maintenance catch-up.

Neighborhood location
