Inner Mission, SF 94110 3642039 7 units · 2 fl · 1929

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 840 Capp 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.

Likely rent-controlled. Building age and unit count suggest this property falls under San Francisco's Rent Ordinance.

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.

Annual rent increase cap

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

840 Capp Street is a 2-story multi-family residential building constructed in 1929, containing 7 units and managed by Copper Hill Inc. The property has undergone several significant structural improvements in recent years, with substantial foundation work being the focus. In 2021, permits were filed for voluntary upgrades to both the front and rear buildings, including brick foundation replacement and garage lateral strengthening, with costs of $90,000 and $35,000 respectively. Previous attempts at similar upgrades were made in 2018 but were withdrawn. The building has seen numerous attempts to increase its unit count, with several permits filed between 2016-2019 for adding accessory dwelling units and legalizing existing units, though many of these permits were either withdrawn or listed as "Filed." In 2016, an approved permit for adding three dwelling units (Units 1A, 1B, and 1C) on the ground floor of the main building and associated structural upgrades was granted, though there have been ongoing concerns about illegal unit conversions.

The building's maintenance history reveals periodic issues with building systems and tenant amenities. There were two separate incidents of hot water outages recorded in late 2010, and several complaints about construction activities in 2012-2014, including unpermitted work and improper construction practices. Multiple building violations have been recorded, including concerning lead paint hazards and various interior surface issues in 2001 and 2004, though many of these were eventually abated. More recent complaints (2012-2014) indicate concerns about electrical work, plumbing issues, and general maintenance problems, though most of these cases are now resolved. The property has also faced regulatory scrutiny, with multiple Notices of Violation (NOVs) issued between 2001 and 2004, including requirements for smoke enclosure improvements and various safety upgrades.

Risk rating

How 840 Capp 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
26thpercentile

Out of 2380 buildings in this neighborhood, 1761 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

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.
