Rent & eviction protection

Is 230-234 Pierce 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
2 or more units

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.

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 property at 230-234 Pierce Street is a two-story, five-unit multi-family residential building located in Hayes Valley, built in 1900 and currently owned by the Martin Mcgrath Living Trust. The building has undergone several significant improvements in recent months, with permits issued in 2024 for replacing nine front windows with aluminum wood clad material and upgrading windows and entry doors in Unit #5. However, there are active complaints from June 2024 regarding unpermitted construction work involving the removal of stairs accessing the back cottage (Unit A) and issues with a non-functioning doorbell. The building's maintenance history shows regular updates to windows throughout the years, with the most recent work continuing a trend of window improvements dating back to 1997.

The property has experienced some safety and security concerns in the past, particularly a notable cluster of violations in 2002 related to security requirements, fire escape obstructions, and security viewer installations, though these were all abated within a month. Historical permits indicate various maintenance work, including rear stair replacement with firewall installation in 1992 and stucco repairs in 1990. The building's 311 call history shows typical urban maintenance issues, including graffiti, parking concerns, and sidewalk cleaning needs, with no recent calls indicating serious problems. The property's records suggest regular upkeep of critical systems, though the recent complaints regarding unauthorized construction and stair removal raise current concerns about building modifications.

Risk rating

How 230-234 Pierce 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
40thpercentile

Out of 1027 buildings in this neighborhood, 616 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 age

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

Estimated permit spend (past 7 years)

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