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 321-323 Collingwood 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 1924
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 321-323 Collingwood Street property is a four-story, three-unit multi-family residential building constructed in 1924 and currently owned by the Chatterjee Family 1997 Trust. The building underwent significant renovations in 2014-2015, including a comprehensive remodeling of all units costing $234,000, followed by various structural improvements such as foundation repairs at five locations ($20,000), replacement of a cracked retaining wall ($10,000), and a complete roof replacement ($10,400). The renovation period also included substantial electrical upgrades, with the installation of new 225-amp overhead service and comprehensive wiring improvements across all units, as well as plumbing enhancements including bathroom remodels and radiant heating installation.

The property has a history of maintenance and safety compliance issues that were addressed in early 2008, including the installation of fire extinguishers, gas shutoff tools, smoke detectors, handrails, and garbage receptacle relocation. While all these violations were officially abated by February 2008, recent records from September 2023 indicate recurring issues with sidewalk parking violations in the vicinity, involving a specific vehicle (blue Audi - 9GBE978). The building's recent history has shown active maintenance and upgrading work, with all major permits from 2014-2015 being completed, including plumbing and electrical systems modernization. The property has maintained compliance with housing codes since resolving the 2007 violations, with no recent building code violations or major maintenance issues on record.

Risk rating

How 321-323 Collingwood 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
25thpercentile

Out of 1278 buildings in this neighborhood, 958 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.

Neighborhood location

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

Estimated permit spend (past 7 years)

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