Haight Ashbury, SF 94117 1244019 3 units · 3 fl · 1906

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 636-640 Ashbury 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

The Tura Family Trust owns this three-unit, three-story multi-family residential building located at 636-640 Ashbury Street in the Haight-Ashbury neighborhood. Built in 1906, this flats and duplex structure has undergone several significant improvements over the years, with the most substantial being a complete reroofing project in 2015 costing $23,360. In 2006, the building addressed multiple violations related to safety and security, completing repairs to interior stairs, fire proofing, and the installation of self-closing devices on exterior doors by September of that year, demonstrating compliance with building and fire safety requirements. An earlier routine housing inspection in 2000 and a 1997 complaint about insulation issues were also resolved.

The building's maintenance record shows regular attention to structural and safety issues, with a code compliance upgrade performed in 1987. More recently, in October 2019, minimal street space-related permits were issued. The surrounding area has experienced typical urban challenges, as evidenced by multiple 311 calls between 2018 and 2024 regarding street cleaning, waste removal, and graffiti, though these external issues do not directly impact the building's internal conditions. Recent exterior maintenance appears to be managed promptly, with the most recent 311 calls in 2024 and 2022 being addressed and resolved accordingly. The building's documented history suggests regular maintenance and prompt response to violations when they occur, with no current active violations or complaints on record.

Risk rating

How 636-640 Ashbury 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
61stpercentile

Out of 581 buildings in this neighborhood, 227 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.

Estimated permit spend (past 7 years)

Dollar value of permits pulled at this address — large recent spend can signal deferred-maintenance catch-up.

Construction spend, owner's portfolio

Estimated permit value across all of this owner's buildings.

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.
