1630 Sutter St

Lower Pacific Heights, SF 94109 0674019 18 units · 3 fl · 1961

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 1630 Sutter 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 1961
2 or more units

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 1961
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 18-unit, 3-story multi-family residential building at 1630 Sutter Street in Lower Pacific Heights, built in 1961 and owned by Chan Family Trust, has undergone several significant improvements and faced recurring maintenance issues over the years. Most recently, in March 2024, the building completed a major upgrade to its fire alarm system, including new panels and devices to meet current safety codes at a cost of $46,200. Other important structural work includes a completed soft-story retrofit in 2016 ($120,000), and the building is currently in the process of adding an ADU unit on the first floor as per Ord# 162-16.

The building has faced multiple safety and maintenance challenges, particularly regarding fire safety systems. Between 2018 and 2023, there have been several fire-related violations and complaints regarding alarms, sprinklers, and exit maintenance, though most have been promptly corrected. Historical issues include water seepage problems in 1997-2000, dry rot repairs in 2021, and a significant clutter/hoarding complaint in 2015. The property has achieved compliance with its Tier 2 soft-story retrofit requirements, and while there were multiple building code violations in the past (notably in 2018 regarding blocked exits and emergency lighting), almost all have been resolved. Recent 311 calls from 2023-2024 primarily relate to street cleaning and debris removal outside the building, rather than building-specific issues.

Risk rating

How 1630 Sutter 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
13thpercentile

Out of 670 buildings in this neighborhood, 583 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.
