Utility notification (may require service upgrade)

Building Permits

May be required for:

New construction or major renovations
Structural modifications (canopy, bollards)
Trenching/underground conduit
ADA accessibility modifications

Utility Coordination

Puget Sound Energy (PSE):

Commercial EV rate available (Schedule 35)
Load management programs for fleet charging
Rebates available through transportation electrification program

Seattle City Light:

Time-of-use rates beneficial for managed charging
EV network partnership programs
Rebates for multifamily and workplace charging

Other Utilities:

Contact your utility early - service upgrades take 2-6 months

ADA Accessibility Requirements

Washington Requirements

Per WAC 51-50-005 and federal ADA standards:

Required Accessible Spaces:

1 accessible space for every 25 EV charging spaces (minimum 1)
44-inch minimum access aisle
8-foot minimum parking space width
Maximum 2% slope in accessible spaces

Charging Equipment:

Operable parts no higher than 48 inches
Clear floor space 30" x 48" minimum
Route to accessible entrance required

Common Violations:

Charging cable too short for accessible parking
Control interface too high
Missing van-accessible spaces

Installation by Property Type

Multifamily Housing (Apartments/Condos)

Challenges:

Multiple parking ownership structures
Electrical capacity limitations
Cost allocation among residents
Future-proofing for increased demand

Best Practices:

Install conduit to all parking spaces ("EV-ready")
Use networked chargers with billing capability
Consider shared charging vs. dedicated spaces
Plan for 20%+ of spaces by 2030

WA Building Code (2021+):

New multifamily buildings must have 10% EV-ready spaces
Additional 25% must have conduit only

Workplace Charging

Charging Strategy Options:

Model	Description	Best For
Free Charging	Employer pays all costs	Recruitment benefit
Cost Recovery	Employees pay per kWh	Cost-conscious employers
Tiered Access	Priority for EVs, regular parking otherwise	Limited spaces

Typical Workplace Installation:

Level 2 chargers (7-11 kW)
4-8 hour dwell time typical
Load management to prevent demand spikes
Integration with parking management

Retail & Hospitality

Key Considerations:

Visibility from road (attracts EV drivers)
Covered canopy preferred (weather protection)
Lighting and security cameras
Amenities during charging (restrooms, food)

Revenue Models:

Free charging (drives foot traffic)
Per-session fees ($)
Per-kWh billing ($$)
Time-based penalties for overstay

Fleet & Municipal Charging

Fleet Depot Requirements:

Higher power Level 2 (19 kW) or DCFC
Managed charging for off-peak operation
Telematics integration
Backup power considerations
