Rent & eviction protection

Is 18 Castro 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 before 1979
Built 1900
2 or more units

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 1900
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 property at 18 Castro Street in the Buena Vista Park neighborhood is a two-unit, two-story multi-family residential building constructed in 1900, currently owned by Chang James Jr & Roeder Har. The building has undergone several significant improvements over the past decade, with the most recent major work being a bathroom remodel completed in 2022 costing $25,000, which included new tiles, fixtures, lighting, and cabinetry. In 2016, substantial renovation work was performed, including bathroom and kitchen remodels, voluntary seismic strengthening, and comprehensive window replacements. The seismic work involved anchoring and bracing of exterior walls, while the window replacement project upgraded to fiberglass windows with improved energy efficiency (U-factor .32 max). Additional modernizations in 2016-2017 included the installation of two forced air furnace systems, new gas lines, and various plumbing and electrical upgrades.

The building's recent history shows ongoing maintenance and infrastructure improvements, with particular attention to safety features like the seismic strengthening work in 2016. The property has experienced some recent municipal service calls, primarily related to street cleaning and parking enforcement, with several cases of driveway blocking citations issued between 2023-2024. The most recent service-related issues involve a report of human or animal waste from June 2023 (still open as of the last update) and some general cleaning requests that have been resolved. While these external issues don't directly impact the building's interior conditions, they reflect the property's environment. The building's permit and maintenance history suggests regular upkeep and modernization efforts by the current owners, with particular attention to systems upgrades (heating, electrical) and safety improvements.

Risk rating

How 18 Castro 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
91stpercentile

Out of 351 buildings in this neighborhood, 32 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
