EV charging in apartments and shared buildings

Apartment charging is rarely just a wallbox purchase. The difficult parts are permission, electrical capacity, cost allocation and a system that still works when more neighbours buy EVs.

Start with the building, not the product page.

Confirm the parking right and approval path

Who owns the parking space? Is it assigned, rented or shared? Who owns the wall, cable route and electrical room? An answer about the flat does not automatically answer these questions.

Ask the building manager or owners’ association for the formal process. Provide a simple proposal with the intended space, cable route, equipment, metering and installer. Do not drill, run a cable or use communal power before written approval.

Tenants should also check the lease and landlord process. Accessibility, fire routes and shared-area rules can affect the design.

What do EU building rules say?

The recast Energy Performance of Buildings Directive, Directive (EU) 2024/1275, sets a direction for charging-ready buildings. Article 14 includes pre-cabling, ducting, charging-point and procedure requirements for defined building categories.

For new residential buildings with more than three parking spaces, it requires Member States to ensure pre-cabling for at least half the spaces, ducting for the remainder and at least one charging point. Related duties apply to qualifying major renovations, with conditions and possible derogations.

The Directive also tells Member States to simplify procedures and remove certain regulatory barriers. This does not mean the same application process already applies in every building across Europe. A directive must be implemented through national law, and property and tenancy law still matter.

Check the current rules in your country and municipality before presenting a legal claim to neighbours.

Assess the building’s electrical capacity

A competent designer or installer should review the supply, existing peak loads, distribution boards, cable routes, earthing, protection and future demand.

The number printed on the main breaker is not the same as confirmed spare continuous capacity. Lifts, heating, ventilation, hot water and commercial units can create large or time-dependent loads.

Define a protected EV power budget. Then decide how many ports it can serve and what service drivers need. Eight cars parked for ten hours may not need eight independent 11 kW supplies.

Use load management deliberately

Dynamic load management can reduce EV charging when the building needs more power and increase it when capacity returns. It can also allocate one site budget across several cars.

Ask practical questions:

• What happens if communication fails?
• Does the system fail to a safe power level?
• Can it prioritize a fleet or accessible space?
• Is it compatible with the chosen meters and chargers?
• Who can change limits?
• Are logs available when a bill is disputed?

Load management creates flexibility. It does not create unlimited energy. If every car needs a large amount before the same early departure, the site may still need more capacity or a booking policy.

Decide how electricity will be measured

Choose a billing model before hardware. Options include a dedicated supply to each space, shared infrastructure with individual metering, or an operator-managed service.

The right option depends on local metering rules, supplier arrangements and how the building wants to administer cost. Consider:

• electricity used by each vehicle;
• charging losses and common system consumption;
• fixed network and service fees;
• installation contributions;
• maintenance and repair;
• users who join later;
• visitors and unauthorized use.

A cheap installation that needs manual spreadsheet arguments every month is not a cheap system.

Build for the next cars

The first driver should not lock the building into a dead end. Plan a shared cable route, distribution architecture and communications approach that can expand.

This does not mean installing a charger at every space immediately. Conduits, cable containment, reserved board space and a scalable controller can reduce later disruption.

Avoid a patchwork of unrelated consumer wallboxes unless a designer confirms how they will share capacity, meter use and fail safely together.

Make access fair and understandable

Agree who can charge and for how long. If spaces are shared, decide whether cars must move after finishing. If spaces are assigned, decide how unused capacity is reallocated.

Publish a short resident policy. Include support contacts, fault reporting, payment, guest use and what happens during a power limit. Keep personal charging data limited to what billing and operation actually require.

The useful first proposal

Bring the owners a staged plan, not a single wallbox request:

1. survey parking rights and cable routes;
2. assess electrical capacity;
3. define the shared power and metering architecture;
4. agree cost and access rules;
5. obtain approvals and quotations;
6. install, test and document the system;
7. review demand before adding more ports.

Shared charging works best as building infrastructure. Solve it once in a way that can welcome the next driver.
