Los Angeles County, California
Calculate the exact number of parking spaces required for your Los Angeles residential project. Parking is one of the most common plan check flags — getting the count wrong means corrections and resubmission. Los Angeles requires 2 spaces per dwelling unit, with additional requirements for ADUs and guest parking on larger projects.
Select your city, number of units, and bedrooms. Indicate whether you're including an ADU and whether you're near public transit — both affect requirements.
Each California city has different parking requirements per unit. We calculate main parking, ADU parking, and guest spaces using your city's municipal code ratios.
See the exact number of stalls required, broken down by type. Transit-adjacent properties may qualify for reduced or eliminated ADU parking under state law.
Parking requirements are one of the most common reasons California building projects get flagged during plan check. Every city sets its own ratios — and they vary significantly.
Key factors that determine your parking requirement:
Getting the stall count right is only half the battle — you also need to plan for the physical space. Standard California stall dimensions:
A rough rule of thumb: each parking space (including its share of the drive aisle) consumes about 300–350 sqft of your site. Use our Setback Calculator to see how much buildable area you have for both structure and parking.
Yes, several ways. Transit proximity is the most common — being within ½ mile of a major transit stop can eliminate ADU parking entirely. Some cities also offer parking reductions for affordable housing, shared parking agreements, or Transportation Demand Management (TDM) plans. AB 2097 (2023) eliminated parking minimums for projects within ½ mile of transit statewide.
Under California state law, ADU parking is waived if the property is: within ½ mile of public transit, within an architecturally or historically significant district, part of an existing primary residence, or when on-street permits are required but not offered to the ADU occupant. Otherwise, a maximum of 1 space can be required. Cities cannot require more than 1 space per ADU.
If you convert a garage to an ADU, the city cannot require you to replace the parking spaces that were in the garage. This is a key provision of California's ADU laws — it prevents cities from using parking replacement as a way to block garage conversions. Your main unit's parking requirement remains unchanged.
California law defines transit proximity as within ½ mile of a "high-quality transit corridor" — typically a bus route with 15-minute headways during peak hours, a rail station, or a ferry terminal. Under AB 2097, the ½-mile radius applies to all residential projects, not just ADUs. Check your city's transit map to see if you qualify.
For residential projects, ADA-accessible spaces are typically required for common parking areas in multi-family projects (4+ units). The ratio is roughly 1 accessible space per 25 total spaces, with at least one van-accessible space. Single-family homes and ADUs generally don't require accessible parking unless they're part of a larger development.
