Nothing on record for this building in the last seven years. Our model still sees a moderate chance of maintenance problems in the next 12 months, from the owner's wider portfolio and the surrounding area rather than from anything recorded here. No public enforcement record to go on. Walk the building, ask the current tenants how repairs get handled, and get any promises in writing.

Rent & eviction protection

Is 4501-4503 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.

Built 1906
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

This two-story mixed-use building at 4501-4503 18th Street, constructed in 1906, contains three residential units and commercial space, currently owned by the Clement & Cobina Chu Revocable Trust. The building has undergone several significant improvements over the past 15 years, including a $9,000 reroofing project in 2018 and comprehensive renovations in 2008-2009 that involved kitchen and bathroom remodels, window replacements, electrical upgrades, and siding repairs at the adjacent 200 Douglass Street address. More recent maintenance includes a meter panel replacement in 2021 due to damage to the wooden utility pole-mounted panel.

The property has experienced various maintenance and environmental challenges in recent years, particularly in 2024-2025, with multiple 311 calls related to tree maintenance issues, graffiti (both public and property-specific), and sidewalk debris. Three open cases from January 2025 involve tree-related problems (overgrown sidewalk, hanging limb) and public graffiti, while previous reports from October-December 2024 documented various instances of garbage and debris, as well as encampment-related concerns. The building's safety record shows two minor fire-related incidents involving barbecue smoke and a carbon monoxide detector activation, neither resulting in injuries. The property's documented improvements suggest ongoing maintenance and upgrading efforts, while the recent external environmental issues indicate challenges related to the immediate neighborhood's public space maintenance.

Risk rating

How 4501-4503 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
20thpercentile

Out of 1278 buildings in this neighborhood, 1022 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
