415 Frederick St

Cole Valley/Parnassus Heights, SF 94117 1267061 3 units · 2 fl · 1900

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 415 Frederick 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
3 units
Property type
Multi-Family Residential
Zoning

Likely rent-controlled. Building age and unit count suggest this property falls under San Francisco's Rent Ordinance.

Based on SF Assessor records. Not legal advice — confirm with the SF Rent Board.

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 415 Frederick Street is a 2-story, 3-unit multi-family residential building constructed in 1900, currently owned by Terence M Hurley. The building has undergone several significant infrastructure upgrades over the past decade, including a $32,500 reroofing project completed in 2018, installation of new water heating systems in 2014 and 2015, and a comprehensive electrical upgrade in 2014 that included a new 200-amp service. The building has a history of maintenance and safety compliance issues, particularly evident in a series of building violations recorded in 2012-2013 that addressed fire safety, security, and structural concerns. These violations included requirements for fire extinguishers, smoke detectors, self-closing doors, and repairs to windows and interior surfaces, most of which were marked as abated by April 2013.

Of particular concern are multiple tenant complaints between 2012 and 2014 regarding illegal units, structural deficiencies, and various habitability issues. Reports documented problems such as poor sound insulation, electrical wiring concerns, plumbing issues, and indications of pest problems. The building's conversion from a 2-family to a 3-family dwelling without providing the required off-street parking spaces was addressed through a variance approval. Recent years show fewer documented complaints or violations, suggesting improved maintenance, though there have been occasional parking enforcement issues on the street outside the building, as evidenced by two citations for blocking the driveway in late 2019. The property underwent several infrastructure improvements between 2012 and 2015, including gas line work and various plumbing upgrades, suggesting ongoing efforts to address the building's systems and infrastructure.

Risk rating

How 415 Frederick 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 526 buildings in this neighborhood, 331 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 size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

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.
