Rent & eviction protection

Is 2451 Post 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
2 units
Property type
Multi-Family Residential
Zoning
RH3
Likely rent-controlled. Building age and unit count suggest this property falls under San Francisco's Rent Ordinance.

Based on SF Assessor records. Not legal advice — confirm with the SF Rent Board.

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 two-unit residential building at 2451 Post Street in Lower Pacific Heights, owned by the Leng Family Trust, is a two-story flats and duplex structure constructed in 1900. The property has undergone several significant modifications to ensure compliance with regulations and improve safety features. Notable renovations include the removal of an illegal kitchen from the ground level (completed in 2004) and the conversion of that space into a laundry area, along with the legalization of a bathroom. The electrical infrastructure was substantially upgraded in 2003, with the installation of two new 100-amp service panels for each unit, new lighting and receptacles, and improvements to the laundry room and rear deck areas. Earlier improvements from 2001 included the rebuilding of the rear stairway and laundry room.

The building's recent history shows regular maintenance and compliance with housing regulations, with the most recent building-related activity being a rent board fee and housing inventory request in November 2024. The property has experienced typical urban challenges as evidenced by multiple 311 calls, including reports of abandoned furniture (October 2024), medical waste (2019), and illegal postings (2019). While these incidents occurred in the vicinity of the property, they are not directly related to building conditions. The only recorded fire-related incident was an accidental alarm system activation with no actual fire or injuries involved. The building's maintenance history suggests a proactive approach to addressing both safety requirements and resident comfort, particularly through the 2004 renovations that focused on bathroom and laundry facilities.

Risk rating

How 2451 Post 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
68thpercentile

Out of 670 buildings in this neighborhood, 214 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.

Building size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

Building age

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

Property class: multi-family flat

2–4 unit flats (class F) are a common SF building type with their own maintenance and complaint patterns.
