623 Clayton St

Haight Ashbury, SF 94117 1246005 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 623 Clayton 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

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 623 Clayton Street is a two-story, three-unit multi-family residential building located in the Haight Ashbury neighborhood, owned by Philip J. Sarrow and constructed in 1900. The building has undergone several significant maintenance and upgrade projects over the years, most notably an electrical service upgrade to 200-amp capacity completed in April 2020, which represents a modern improvement to the building's infrastructure. In 2007, the building required attention to its external stairways, with permits issued for repairs to treads and stringers, though records from that period also show a complaint about an alleged illegal unit that was investigated and abated by July 2009. Earlier maintenance work included termite repairs completed in 1995, and foundational improvements in 1990 when the building's foundation was secured with bolting. More recent neighborhood interactions have been primarily related to street-level issues, including two 311 calls in 2021 regarding parking violations and loose garbage, though these were not directly related to the building's condition or management. The property was also the subject of telecommunications equipment installation in 2018-2019, when AT&T placed wireless antenna system equipment on a light pole adjacent to the building, with all necessary planning and CEQA clearances obtained and properly documented.

Risk rating

How 623 Clayton 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
55thpercentile

Out of 581 buildings in this neighborhood, 261 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.
