Rent & eviction protection

Is 4505-4507 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 1938
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 three-story duplex at 4505-4507 18th Street, owned by Pasion Teodulo B & Theresa and built in 1938, has experienced several significant events in its history, with the most substantial issues occurring in 2007. That year, the property faced multiple violations related to stair safety and storage concerns, including problems with exterior stairs that required multiple permits for repairs totaling $2,650, as well as fire safety violations regarding combustible storage. A complaint filed that same year also indicated potential illegal dwelling unit concerns in the garage area, though this and similar past complaints about a cleaning business operating from the garage were eventually abated by 2012. The building underwent a complete reroofing project in 2005 costing over $12,000, and in 2017 both units experienced tenant buyouts for $50,000 each.

Recent activity at the property has been relatively minimal in terms of structural issues, with only routine maintenance matters being reported. Between 2020 and 2024, there have been several parking enforcement requests regarding blocked driveways, along with a few street cleaning issues. Most recently, in late 2023, the property experienced some general maintenance and cleaning needs in the surrounding area. A notable planning record from 2017 showed a proposal for subdividing the two lots into three, though this appears to have been an administrative matter regarding lot configuration rather than any physical changes to the building itself. The property's historical records indicate it has been relatively stable since resolving the 2007 violations, with no active building or safety concerns reported in recent years.

Risk rating

How 4505-4507 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
83rdpercentile

Out of 1278 buildings in this neighborhood, 217 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
