Rent & eviction protection

Is 651-653 18Th 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.

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 651-653 18th Avenue in the Central Richmond neighborhood is a two-story flats and duplex structure built in 1923, currently owned by William M J and Diana Dea. The building's maintenance record shows two permitted renovations from 1991, including the installation of vinyl siding on the back wall and replacement of kitchen cabinets, both of which were completed successfully.

The property has experienced recurring urban maintenance challenges in its vicinity, with several 311 calls primarily related to street cleaning and debris issues between 2019 and 2024. Most recently, in spring and fall of 2023, there were incidents of loose garbage requiring cleanup. The area has also faced multiple reports of abandoned vehicles between 2021 and 2022, though in most cases, the vehicles were either gone upon arrival of enforcement officers or complied with the law when addressed. Additional infrastructure concerns include a pavement defect reported and resolved in 2019, and a documented instance of sidewalk parking in May 2021, though the offending vehicle could not be located when officers responded.

Risk rating

How 651-653 18Th 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
52ndpercentile

Out of 2250 buildings in this neighborhood, 1080 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
