175 Castro St

Duboce Triangle, SF 94114 3540035 4 units · 2 fl · 1954

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 175 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 1954
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.

Built 1954
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-story, four-unit multi-family residential building at 175 Castro Street in Duboce Triangle, owned by Antonia & Dolores M Loprest, was constructed in 1954. The property's significant historical modifications include the documented removal of an illegal fifth unit in 1989, which was accomplished by removing a kitchen. In 2016, the building underwent reroofing work valued at $9,320, and in 2004, one wood window was replaced with vinyl at the rear of the building. The property experienced notable safety and compliance issues in 2001, when multiple violations were documented including the need for guardrails, proper fire extinguishers, and building permits; all these violations were abated by October 22, 2001.

More recent concerns include several maintenance issues from 2007, particularly regarding problematic steps leading to a deck and recurring mold problems in a closet, though these were resolved by December 2007. Routine inspections occurred in 2001 and 2011, with no significant ongoing issues noted. The building's immediate surroundings have experienced recent challenges including multiple reports of graffiti and one instance of loose garbage in late 2023, though these were handled promptly by city services. While the building's documented history shows a pattern of permit-related issues in the late 1990s and early 2000s, there have been no recent building code violations or safety concerns on record since 2011.

Risk rating

How 175 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
37thpercentile

Out of 287 buildings in this neighborhood, 181 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
