Rent & eviction protection

Is 3993 18Th 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.

15+ years since occupancy
Built 1875
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, 1-story multi-family residential building at 3993 18th Street in the Eureka Valley/Dolores Heights neighborhood, owned by the Suzanne F Boyle Revocable Living Trust, has a documented history dating back to its construction in 1875. The property has undergone several maintenance updates over the years, with particular attention to the roof, having received reroofing in 1990 ($5,000), 1996, and most recently in 2015 at a cost of $6,000. Window improvements were attempted in 1997 with the installation of two vinyl windows, though this permit ultimately expired.

The building's recent history (2023-2024) has been marked by ongoing maintenance needs in the surrounding area, with multiple reports of graffiti affecting both public structures (such as poles and bike racks) and the building itself. While the most recent graffiti incident on the building (August 2023) was categorized as offensive, other documented graffiti incidents were deemed not offensive. The property has also experienced recurring issues with street cleanliness, evidenced by multiple 311 calls regarding loose garbage and debris, though most of these cases have been resolved through city intervention. Notably, there was one encampment cleanup reported in December 2023 that required further assessment after initial engagement. The building's documented permit and maintenance history shows regular upkeep of critical building systems, particularly the roofing structure, though there are some historical permits that expired without confirmation of completion.

Risk rating

How 3993 18Th 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
97thpercentile

Out of 1278 buildings in this neighborhood, 38 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
