Parking Solutions
Resident vs. visitor stalls, surface vs. structured vs. tuck-under, garage allocation per unit, and the walking-distance rule that drives resident satisfaction more than any other design choice.
Multifamily parking is its own discipline — measured every day, in the dark, with groceries.
Multifamily parking is its own discipline. The rules that govern commercial parking — maximize stalls, minimize walk to the storefront — don't translate cleanly to a residential site where the same stall serves the same person for years and the walking distance is measured every day after work, in the dark, with groceries.
The full multifamily parking package.
- Parking yield analysis with resident, visitor, and accessible stall counts
- Surface, structured, tuck-under, and carport configurations sized to density
- Stall assignment strategy aligned with rental or for-sale operating model
- Walking distance analysis from every stall to every unit door
- ADA stall distribution across the site (not clustered at one entry)
- EV charging infrastructure conduit and panel capacity for future build-out
Designed for the resident, not just the zoning floor.
The parking ratio is the starting point and the easiest thing to miscalculate. Most Treasure Valley cities specify minimums in the range of 1.5 to 2.0 stalls per unit, plus visitor parking at roughly 0.2 to 0.3 stalls per unit. The minimums are floors, not targets — a project with one-bedroom units in a transit-poor location might be miserable at 1.5, even when the city signs off. Bailey runs the parking math against the unit mix and the actual transportation context, not just the zoning floor, and we tell clients when the floor isn't enough.
Stall geometry is straightforward but unforgiving. The standard is nine-by-eighteen-foot surface stalls with twenty-four-foot two-way drive aisles for walk-up apartment buildings, and that's the standard for almost every garden-style project we work on. Some municipalities allow narrower compact stalls; we don't recommend them on rental sites because compact stalls invite parking complaints and damaged side mirrors. ADA stalls add a five-foot access aisle to one side of the stall, and they have to be distributed across the site rather than clustered at the leasing office — every cluster of buildings should have an accessible stall within reasonable walking distance.
Walking distance is the design rule that matters most. The maximum distance between unit entry and parking should be designed for, not assumed. The industry rule of thumb is 300 to 400 feet maximum, and resident satisfaction starts dropping past 300. Bailey draws the walking-distance circles from every stall during layout, and we adjust the cluster geometry until every unit has parking within tolerance. The math gets tighter on bigger sites — and that's exactly when surface parking starts breaking down.
Above three stories or above 25 units per acre, surface parking stops working and the design moves to structured or tuck-under configurations. At thirty to forty units per acre, parking has to be subsurface or structured. Tuck-under (parking on the ground level of the residential building) is the cheapest structured option and works well at three to four stories. Above that, podium parking — a full parking deck under the residential — becomes the right answer. Each step up the structure ladder adds cost and adds design complexity, but it also adds density and shortens walking distance dramatically.
Carports are the underrated middle option. Sheltered parking — carports or individual garages — is increasingly common in upscale garden apartments, and the math often works. A carport adds maybe 15% to the cost of a surface stall and gives residents weather protection, snow shedding, and a perceived ownership of the stall. In Treasure Valley winters, that's a real amenity. Bailey designs carports into the parking field as a premium-rent feature, not as an afterthought, with snow load and fire access engineered to code.
EV charging is the last layer and the one that's still evolving. The right move on most new multifamily projects is to install panel capacity and conduit for at least 10% of stalls now, with structural provisions for expanding to 30–50% over the project's life. Codes are tightening every cycle, and building in the conduit during construction is dramatically cheaper than retrofitting later. Bailey coordinates the panel sizing with the building electrical engineer and runs the conduit during the parking lot installation, so the project is ready when the next code cycle hits.
