Los Angeles sets each parking fine as a flat amount. A ticket for the same violation carries the same price in Bel Air and Boyle Heights, even though median household income is $169,187 in the city's richest tenth of census tracts and $38,504 in its poorest.
That flat price reaches household budgets differently. Across the poorest tenth of city tracts, a year of parking fines issued works out to $163.97 per household. Across the richest tenth, it is $72.77.
The dollar difference is 2.25x. Once each amount is measured against the income of a household in the tract where the ticket was written, the difference becomes 9.9x.
The poorest tenth is issued parking fines equal to 0.426 percent of household income in a year. In the richest tenth, the figure is 0.043 percent. The same system of flat fines produces two very different weights.

The city line matters
This analysis covers 25,007,005 City of Los Angeles parking citations, carrying $1,830,496,595 in fines issued from 1 January 2014 through 19 August 2026, and geocoded to 1,093 city census tracts with 100 or more households; income, household and tenure figures are ACS 2020-2024 five-year estimates. Using Los Angeles County income groups would mismatch the city citation file with a larger geography, because tracts outside the city are 43 percent of county tracts but carry only 0.6 percent of fines in this file, or $0.68 per household per year against $101.05 inside the city. That missing coverage is uneven, with 81 percent of the county's poorest tenth inside the city and 49 percent of its richest tenth, so a county comparison would turn absent citations from other cities into an inequality finding.
Income creates the larger divide
The $163.97 issued per household in the poorest tenth is higher than the $72.77 in the richest tenth, but those amounts alone do not produce the steepest divide in the record. They differ by 2.25x. Measured against income, 0.426 percent against 0.043 percent, the divide is 9.9x.

The difference between the two measures comes from the denominator. The fine schedule does not change with a tract's income, while the income available to absorb it does. A set of tickets that is already larger in poorer tracts becomes much heavier when it is placed against a smaller household budget.
This is a tract comparison, so it describes the places where citations were written. It does not establish that the driver ticketed in a lower-income tract lives there or earns the tract's median income. That distinction matters most in places where visitors leave many cars at meters and time limits, and it is why the analysis also tests violation families more closely tied to residents.
Renting marks the pattern, crowding helps explain it
The share of households that rent is 90.8 percent in the poorest tenth of tracts, compared with 31.5 percent in the richest tenth. Across all 1,093 tracts, renter share and parking burden move together at Spearman +0.72, a strong rank relationship. It does not make renting itself the cause, and it does not identify the tenure of a ticketed driver.
The second relationship points toward the physical conditions beneath tenure. As street miles per household decline, fines per household tend to rise, with a Spearman rank correlation of -0.38. Measured per street mile, the poorest tenth has 7.5x the fines issued in the richest tenth. Less street space per household is consistent with more competition for each stretch of legal kerb, whether the difference comes from the built form, the intensity of enforcement, or both.

The extra tickets are for obstruction
The obvious explanation did not hold. A household without a driveway may have to leave a car on the street and move it for sweeping, but the street cleaning family, which also includes preferential permit parking and overnight restrictions, is only 1.7x higher in the poorest tenth. It accounts for $36.66 per household per year there and $21.99 in the richest tenth. Registration citations are also 1.7x higher, $4.35 against $2.56.
The violation family that most separates the two ends is obstruction: red zones, hydrants, blocked driveways, double parking and sidewalks. It accounts for $66.22 per household per year in the poorest tenth, against $23.25 in the richest, a 2.8x difference. Obstruction makes up 40.4 percent of everything the poorest tenth is fined for. That is a crowding finding, not a carelessness finding.

The category mix narrows what the record can support. Street cleaning and registration have the clearest connection to residents because they concern where a car is regularly stored and whether it is kept registered. Restricting the analysis to those two families reduces the burden ratio from 9.9x to 7.3x, but does not remove it.
Bus lanes add a new edge
Transit citations include bus lanes and bus zones. They account for $15.53 per household per year in the poorest tenth and $3.55 in the richest tenth, a 4.4x difference, the sharpest ratio among the listed violation families.
The bus lane camera programme issued its first citations in this file in September 2024, so it occupies only the recent end of this record. Its siting adds a present-tense layer to a pattern built over the full coverage period, but the short run should be read separately from the longer history of parking enforcement. The programme's 4.4x split is a coda to the broader finding, not its foundation.
What's still unclear
There are two obvious caveats here.
First, the datasets used measure the location at which a citation was issued, not the residency of the vehicle's owner. This cuts both ways and could result in the undercounting of wealthier people receiving tickets in lower-income neighborhoods. However, based on the geographic data attached to car make, our analysis is that this likely doesn't move the needle very much.
Caveat two is the clear alternative explanation, density. The city's densest neighborhoods also happen to be some of its lowest income, and this analysis doesn't claim to separate those factors. The household burden remains though.
Finally, we project that the true cost is likely even higher than demonstrated here, due to the largest factor we cannot verify but that is most likely at play: towing, and ability to pay the fine. None of the records consulted in this analysis cover the costs associated with unpaid tickets, late fines, registration holds, and towing, all of which are significantly more likely to be felt by lower-income households.
Equal fines produce unequal outcomes
The flat fine is the fixed part of this record. The conditions around it are not fixed: household income, renter share and available street space all change across Los Angeles, and the citation mix changes with them.
Within the city boundary, the poorest tenth is issued 2.25x as much per household and carries 9.9x as much as a share of income. The largest part of the added dollar amount is obstruction, not street cleaning. Los Angeles sets one price for a violation, but where that citation is written determines how much of a local household income that price represents.
