10-20 Edgardo Pl

Telegraph Hill, SF 94133 0077040 9 units · 3 fl · 1959

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 10-20 Edgardo Pl 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 1959

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 1959
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-story, nine-unit multi-family residential building at 10-20 Edgardo Place in Telegraph Hill, owned by Sanger Edgardo-lombard Lp, has a documented history of maintenance and safety issues spanning several decades since its construction in 1959. Most recently, there have been sewer-related concerns with two discharge incidents reported in 2024, and in 2015, multiple complaints regarding water intrusion, structural problems, and mold issues were filed and investigated by the Building Inspection Division and Housing Inspection Services. The building has undergone several significant modifications, including horizontal and vertical additions in the late 1980s and early 1990s, roof repairs and strengthening work in 1995, and the installation of a sprinkler system in 1985. A substantial cluster of building violations was documented in 2006, primarily related to fire safety and security issues, including problems with fire extinguishers, fire escape maintenance, and security gate self-closing devices, though these were all abated by June 2006.

Earlier concerns include heating system problems in 2003-2004, with complaints about inadequate heat for extended periods, and various roof-related issues noted in the 2002 violations. The building's plumbing infrastructure was addressed in 2010 with a sewer replacement project, though this permit has since expired. More recent concerns have primarily involved external issues such as tree damage (most recently reported in 2024) and parking violations, with the most recent tenant buyout information showing no recorded buyouts at this address. A significant incident regarding illegal short-term rentals was documented at 16 Edgardo Place in 2019, which was resolved through city intervention. The building's history suggests ongoing maintenance challenges, particularly in relation to water and fire safety systems, though many historical violations have been resolved or are no longer active.

Risk rating

How 10-20 Edgardo Pl'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
5thpercentile

Out of 684 buildings in this neighborhood, 650 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 location

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