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 21-23 Noe 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.

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 three-unit multi-family residential building at 21-23 Noe Street in Duboce Triangle is a historically significant two-story structure built in 1900, currently owned by the Dean M Gridley 2012 Revocable Trust. The property has undergone several substantial renovations and infrastructure upgrades over the years, with the most significant work occurring between 2004-2006 when a horizontal addition was attempted (though the permit expired), which included demolition and reconstruction of rear porches and stairs, and the installation of fire sprinklers in a new dining room addition. The electrical infrastructure received considerable attention during this period, with a 400-amp underground service upgrade and extensive electrical work for lighting, switches, receptacles, and laundry facilities, though many of these permits expired before completion, requiring renewals and additional permits to finalize the work in 2006-2007.

More recent history shows some concerns regarding building safety, notably a lead paint complaint in 2012 that was filed and abated within two months. The building has experienced several maintenance and safety-related issues in the surrounding area, particularly regarding sidewalk infrastructure, with an open case for a collapsed sidewalk reported in February 2020, though this is a street maintenance issue rather than a building concern. The property's parking situation has generated multiple complaints, with two documented instances of sidewalk parking in 2019 and 2021, though enforcement officers were unable to validate the issues in both cases. The building's historical records also show earlier work from 1996 involving foundation repairs, though this permit expired. While the property has experienced various maintenance and compliance issues over the years, the documentation suggests that most recent major infrastructure improvements were completed between 2005-2007, with no recent building permits or significant complaints on record.

Risk rating

How 21-23 Noe 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
38thpercentile

Out of 287 buildings in this neighborhood, 178 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.

Estimated permit spend (past 7 years)

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