Rent & eviction protection

Is 636-638 Cole 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 1903

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 1903
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-unit residential building at 636-638 Cole Street in Haight Ashbury, constructed in 1903, has undergone several significant renovations and maintenance work over the past decades. Most recently, in 2020-2021, the property underwent bathroom renovations including the installation of additional toilets and sinks in both units. The building has seen regular maintenance of its roof, with reroofing work performed in 2015 and 2018, though the 2018 permit was valued significantly lower than the 2015 work. A notable safety concern was addressed in 1996 when an emergency removal of a dangerous parapet was completed, followed by structural repairs to reinforce the wall. The property has had two major sets of renovations in 2010, including kitchen remodels in both units and significant electrical upgrades to replace ungrounded outlets, totaling approximately $56,000 in work.

The building has experienced some maintenance challenges, particularly in 2009 when electrical problems were reported, including sparking sockets and issues with the rear stairs, though these violations were abated by July 2009. Multiple plumbing improvements were completed in 2010, including chimney flue installation for water heaters and furnace, along with various valve replacements. More recently, the building has had several parking-related issues documented through 311 calls in 2021-2023, primarily involving vehicles blocking the driveway or parking on the sidewalk, though these are external issues not directly related to building condition or maintenance. The property underwent a condo conversion process as indicated in planning records, though no developer information is listed.

Risk rating

How 636-638 Cole 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
79thpercentile

Out of 581 buildings in this neighborhood, 122 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.

Neighborhood location

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

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.

DBI complaint rate, owner's portfolio

Per-building complaint rate across the owner's portfolio.
