Rent & eviction protection

Is 1697-1699 23Rd Ave 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.

Built 1927
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 property at 1697-1699 23rd Avenue in the Central Sunset neighborhood is a two-unit, two-story multi-family residential building constructed in 1927, currently owned by Jason Martinez and Linh Ly. The building has undergone several significant maintenance and improvement projects over the years, including window replacements (2004), kitchen renovations (2010), roofing work (2008), and more recent plumbing work including a gas line extension (2018). However, the property has also experienced multiple issues that may impact resident quality of life. A notable series of complaints and violations in 2010 involved unauthorized kitchen demolition work, including the removal of sinks, cabinets, and flooring, which led to a notice of violation that was eventually resolved through permitted repairs. More recently, in April 2019, there were complaints regarding work without permits, including mold remediation, dry rot issues, and exterior stucco problems.

The building's recent history shows some maintenance challenges, with a sewage backup incident reported in December 2024 and multiple complaints about garbage and debris in November 2024. The property has gone through several tenant buyouts between 2019 and 2024, with the most recent one at 1690 24th Avenue in May 2024 involving a compensation amount of $125,000 for one tenant. While the building has received attention through various permits and repairs over the years, including electrical and plumbing improvements, the frequency of complaints and code violations in past years suggests a pattern of maintenance issues that have required corrective actions. The most recent tenant buyout activity and the age of the building (over 95 years old) indicate ongoing changes to the property's occupancy and potentially its maintenance requirements.

Risk rating

How 1697-1699 23Rd Ave'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
34thpercentile

Out of 814 buildings in this neighborhood, 537 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
