Rent & eviction protection

Is 4543-4545 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 1904
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-unit TIC building at 4543-4545 18th Street, owned by Corey Lambert, has undergone significant renovations since 2016, with work primarily focused between 2016-2018. Major improvements included soft-story reinforcement on the first floor, complete interior remodels of multiple units involving kitchen and bathroom renovations, electrical rewiring, and plumbing upgrades. The building experienced a cluster of concerns in late 2016, with several housing violations filed on November 7, 2016, including issues with mold/mildew, damaged walls, broken light fixtures, and security concerns, though these were all abated by May 15, 2017. There were also multiple complaints about construction practices in late 2016, including unpermitted work, safety hazards, and improper disposal of materials.

Recent activity has been primarily maintenance-related, with various permits showing ongoing improvements to individual units. Two notable construction-related complaints were filed in late 2017 and 2018 regarding after-hours work and holiday noise. The building's systems have received attention during the renovation period, including furnace replacements and comprehensive electrical system updates. Historical records show earlier issues with exterior stairs requiring rebuilding in 2009, and a routine inspection in 2013 noted heating problems and mold concerns. The property has continued to receive regular maintenance, as evidenced by recent 311 calls regarding sidewalk cleaning, tree maintenance, and waste management. While the building underwent significant improvements from 2016-2018, most recent complaints have been non-structural in nature, focusing on exterior maintenance and environmental concerns.

Risk rating

How 4543-4545 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
48thpercentile

Out of 1278 buildings in this neighborhood, 665 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
