Pacific Heights, SF 94115 1022005 4 units · 2 fl · 1900

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 1817 Lyon 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 1900

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 1900
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 multi-family residential building at 1817 Lyon Street in Pacific Heights is a two-story, four-unit apartment structure built in 1900, currently owned by the McGee/Swain Family Trust. The property has undergone several significant maintenance and improvement works over its lifetime, with the most recent being a filed permit in June 2022 for unit #3 to allow for the use of an ILO (In-Law Unit) within the existing legally permitted structure. The building has received attention to its roofing needs in 1989 and 2007, with both reroofing projects completed at costs of $5,500, and termite repairs were performed in 1995. Historical records also show some interior renovations in 1990 involving bathroom modifications.

The building has undergone several routine housing inspections over the years in 2000, 2008, and 2011, with no active violations noted from these inspections. However, there is an active plumbing-related complaint from 1997 concerning the building's sewer system, which has been documented as having excessive grease issues and connections to neighboring properties through a six-inch clay pipe, requiring multiple instances of snaking and partial replacement of 25 feet of sewer pipe, with the problem recurring despite repairs. The only recent maintenance issue noted was a 311 call in June 2021 regarding illegal postings on street furniture, which was resolved by city cleaning services.

Risk rating

How 1817 Lyon 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
54thpercentile

Out of 963 buildings in this neighborhood, 443 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.

Estimated permit spend (past 7 years)

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

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.
