Rent & eviction protection

Is 4017 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.

Built 1907

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 1907
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 4017 18th Street, owned by Thomas P Rodgers, is a two-story flats and duplex structure built in 1907 in the Eureka Valley/Dolores Heights neighborhood. The property's maintenance history shows relatively regular upkeep, with the most significant recent work being a 2017 roof replacement including cleaning, felt installation, and new shingles at a cost of $10,500. The building underwent several improvements in 1988-89, including kitchen renovations and the installation of exhaust fans, as well as a horizontal addition, all of which were successfully completed. The property experienced a plumbing issue in 2005 when wastewater lines serving both units' kitchen sinks leaked, though this was promptly resolved within two weeks.

The building has faced recurring issues with the adjacent sidewalk infrastructure, with three documented sidewalk defect reports in 2020 and most recently in December 2024, when a collapsed sidewalk was noted. Tree root damage affecting the sidewalk was reported and is currently open as of July 2022. The property has also been subject to various street sanitation matters, including reports of graffiti (2023), garbage (2019), and waste clean-up needs (2018), though all these issues were resolved. A brief sprinkler/standpipe system issue was reported and corrected in September 2017. The planning records indicate no active development proposals or concerns.

Risk rating

How 4017 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
77thpercentile

Out of 1278 buildings in this neighborhood, 294 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.

Model explanation

What's driving this score

The three data points that most influenced this building's risk rating — ranked by the weight the model placed on each one.

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.

Building permits, owner's portfolio

Permits pulled across all of this owner's buildings over 7 years.
