728-730 Washington St

Financial District North, SF 94108 0194007 23 units · 4 fl · 1925

Nothing on record for this building in the last seven years, but our model still flags a rising risk of maintenance problems in the next 12 months. That forecast comes from the owner's wider portfolio and the surrounding area, not from this building's own record — treat it as a reason to ask questions, not as evidence of a problem. 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 728-730 Washington 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 1925
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 23-unit, 4-story multi-family residential building at 728-730 Washington Street in the Financial District North, owned by Chin Jin H & Jane H Trust, was constructed in 1925 and has undergone numerous renovations and faced several significant issues over the years. Most recently, there are open violations from 2023 related to sleeping area requirements and alarm system maintenance. In 2015, a serious incident occurred when the building's boiler was turned off by PG&E due to hazardous carbon monoxide leaks, though this was resolved by August 2015. The building has experienced recurring issues with its fire safety systems, as evidenced by multiple violations and complaints between 2017 and 2024 concerning alarm systems, sprinklers, and fire extinguishers, with the most recent violation in November 2023 still pending resolution.

The property has undergone various unit renovations, including substantial bathroom and kitchen remodels in units 206, 401, 405, and 406 between 2009 and 2016, with associated electrical and plumbing upgrades. A notable cluster of complaints in 2014 pointed to maintenance issues, including lack of heat, mold concerns, and various repair needs that were subsequently addressed. The building's systems have required ongoing attention, with electrical panel replacements (notably addressing outdated Federal Pacific panels in 2017) and temporary tiebacks installation in 2019. Historical violations from 2002 included various fire safety concerns, lead paint issues, and egress problems, though these were all abated by February 2002.

Risk rating

How 728-730 Washington 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
17thpercentile

Out of 145 buildings in this neighborhood, 120 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.

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

Building size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

Neighborhood (ZIP code)

The ZIP code captures local housing market and enforcement patterns that affect all buildings in the area.
