Summary

Lower Merion Township's Subdivision and Land Development Code, Section 135-4.9R, requires new development to build in electric vehicle charging capacity, not just parking. Projects adding more than 25 spaces must wire at least 20% of them for Level 2 charging, new parking structures must be fully EVCS-capable, and new single-family and multifamily garages need a dedicated 40-amp circuit and outlet ready for a charger.

R. Electric vehicle charging stations (EVCS). ... (1) Electric vehicle readiness standards. (a) For any new development or redevelopment requiring more than 25 additional parking spaces, sufficient space and capacity shall be provided to support the operation of Level 2 EVCS for at least 20% of the additional parking spaces, with a dedicated branch circuit and overcurrent protection for each Level 2 EVCS. ... (2) EV parking capacity and minimum required parking requirements. (a) For any new development or redevelopment with at least 10 parking spaces serving residential uses, at least 10% shall be electric vehicle parking spaces (EVPS) served by a Level 1 or Level 2 EVCS connection. (b) For any new development or redevelopment requiring 25 additional parking spaces, at least 5% shall be EVPSs served by a Level 2 EVCS connection. At least one EVPS, or 10% of the EVPSs generated to meet this requirement, whichever is greater, shall be available for public use.

Full Breakdown

Section 135-4.9R, Electric vehicle charging stations (EVCS), sits inside the Complete Streets and context-sensitive design standards of Chapter 135, the Subdivision and Land Development Code, and applies to new development and redevelopment plans reviewed by the Township. Under the EV readiness standards, any project adding more than 25 parking spaces must provide enough space and electrical capacity for Level 2 EVCS at at least 20% of the additional spaces, each with its own dedicated branch circuit and overcurrent protection. Any new or redeveloped parking structure must make every space EVCS-capable, with conduit run throughout and subpanels sized for a Level 2 charger delivering at least 32 amps/7.7 kWh per space.

New single-family and multifamily dwellings with garages must include a dedicated 40-amp branch circuit and a 220-240-volt/40-amp outlet inside the garage. Beyond readiness, the ordinance sets minimum built EVCS counts: 10% of spaces in residential projects with at least 10 spaces, 5% of spaces (Level 2) for projects adding 25 or more spaces, with at least one space or 10% of that share open to public use, and 1% on a Level 3, 150 kWh port for projects of 250 or more spaces. Design rules require retractable or hung cords that never cross a driveway or sidewalk, ADA-compliant mounting, pedestals set back at least four feet from the curb, and physical protection such as bollards or wheel stops offset at least 24 inches. A maintenance and operation plan needs Township Engineer approval, and each station must post voltage/amperage, hours, fees and a contact number for reporting outages.

Violations & Fines

Section 135-4.9R is a land development standard, not a stand-alone penalty clause: a project that does not meet the EV-readiness and EVCS-capacity thresholds cannot receive subdivision or land development plan approval from the Township, since compliance with Chapter 135's design standards is a condition of that approval. The Township Engineer must also approve each site's maintenance and operation plan before the charging stations go into service, giving the Township a second checkpoint to require fixes before a project is finaled.

Frequently Asked Questions

Does Lower Merion require electric vehicle charging in new developments?
Yes. Section 135-4.9R of the Subdivision and Land Development Code requires EV-readiness and, above certain size thresholds, actual EVCS installation for new development and redevelopment, covering surface parking lots, parking structures, and new single-family and multifamily garages built or rebuilt in the Township.
How many parking spaces need EV charging capacity?
Projects adding more than 25 spaces must make at least 20% Level 2 EVCS-ready. Residential projects with 10 or more spaces need 10% built as EVPS; projects of 250 or more spaces need 1% on a Level 3, 150 kWh port available to the public.
Do new houses in Lower Merion need EV wiring in the garage?
Yes. New single-family and multifamily dwellings with garages must include a dedicated 40-amp branch circuit and a 220-240-volt/40-amp outlet located inside the garage, sized to power a future Level 2 charging station, under Section 135-4.9R(1)(c) of the Township's Subdivision Code.
