EV charging at a villa or in a community building: power, rights and installation

In a community building a charger on your own garage space needs prior notice to the community; at a villa it comes down to supply capacity and the panel. Rules, ITC-BT-52 power levels, paperwork and what to pre-wire during a renovation.

Can I install an EV charger in a community building in Spain?

Yes. If you own an individual garage space in a building under horizontal property in Catalonia, article 553-36.3 of the Codi civil de Catalunya does not require a vote at the owners' meeting: you send the technical project to the community's president or administration 30 days before starting and, once finished, the installation's technical certificate. The installer's bill and the electricity used are paid by whoever wants the charger. At a villa outside any community you do not have to ask neighbours, but the technical wiring rules still apply.

One caveat up front. Catalonia has its own civil law (book five of the Codi civil de Catalunya), and article 17.5 of the Spanish Ley de Propiedad Horizontal, which asks only for prior notice, does not apply here. Within those 30 days the community may propose a reasonable alternative that suits its interests better; if it does not carry it out within two months, you can go ahead with the installation you planned. How this fits your building should be confirmed by the administrador de fincas or a lawyer before you order anything. The simplified route in the article is tied to an individual space. If the charger means touching common elements (a new riser, an upgrade to the building's main supply, a cable run through shared areas), notice is not enough and the matter goes to the owners' meeting. If you rent the space, you need the landlord's consent.

Send the notice in writing through the administrador, with a date, the technical project, a sketch of the cable route and the installer's details. That leaves a paper trail and removes any basis for a neighbour to dispute the work later. For the wider question of when works need community approval, see our guide on community authorisation for works.

What power does a villa need to charge an electric car?

For a villa, a 7.4 kW single-phase or 11 kW three-phase charger is usually enough. A car with a battery of about 60 kWh charges at 7.4 kW in roughly 8-10 hours, so overnight; at 11 kW it is faster. Fitting 22 kW for speed rarely pays off: many models accept 11 kW on AC and only some take 22, so check your car's spec sheet.

The rules for homes come from ITC-BT-52 of the REBT (Real Decreto 1053/2014). A single-family house gets a dedicated circuit for charging only: the C13 circuit, installation scheme 4a. The standard power steps are 3,680 W (16 A, single-phase) and 22,170 W (32 A, three-phase). A single-phase C13 circuit should not exceed 9,200 W unless the designer justifies more.

In practice the constraint is not the charger but the contracted power and the panel. A villa on a 9-11 kW contract with air conditioning, a pool and an induction hob, plus 7.4 kW for the car, will trip the main breaker at the evening peak. There are two ways out: raise the contracted power and move to a three-phase supply (through the installer; the request is processed by the distribution company), or fit a charger with dynamic load management that drops its current when the house is drawing a lot. With two cars, load management is close to mandatory. How the power is calculated and when three-phase makes sense is covered in our guide on the electrical panel and three-phase supply.

Do you need a permit to install a charger?

At a villa no owners' vote is involved, but you do need a registered installer. They build the circuit to the REBT and issue the installation certificate (boletín, CIE). Whether a technical memorandum or a full project is needed depends on the power and the location, and the installer decides it under the low-voltage regulation and Generalitat requirements. The CIE process is explained in a separate guide.

A municipal licence for a charger on your own plot is normally not required. The exceptions are a protected facade, a historic ensemble, or a spot visible from the street; in those cases ask the ayuntamiento before you order. In an urbanización with its own community (shared roads and gates), read the statutes: there may be rules on the appearance of walls and boundary fences.

Once it is installed, tell your insurer and check that the home policy does not exclude damage of electrical origin. It is five minutes on the phone; if there is a fire from an unregistered line, the conversation will be very different.

What to check in the wiring and the quote before installation?

Check four things: protection, cable, route and control. Under ITC-BT-52 each connection point gets its own residual-current breaker of 30 mA maximum, class A, and an omnipolar circuit breaker with a C curve. In a single-family house, mode 3 with a type 2 connector at 16 or 32 A is allowed. If the quote lacks those lines, or shows one shared protection for the garage and the charger, that is a red flag.

The cable size is calculated from length and voltage drop. From the panel to a detached garage 30-40 metres away you need a different cable than for 8 metres to an attached garage. Across the garden it should be a trench with corrugated duct, not cable laid straight in sand; check who reinstates paving and lawn and whether it is in the price.

Decide on control from the start: dynamic load balancing, consumption metering, app or RFID access, and the option to charge from solar panels. If a second car is likely, lay ducts for two points now; the cable can be pulled later. It is a cheap line during a renovation and an expensive one after the stone and landscaping are in.

Outdoors, the unit's housing must be rated for external mounting: protection class and temperature range are in the manufacturer's data sheet, and on the coast add resistance to salt air.

How much does it cost to install a home charger?

By eye, not from a price list: a 7.4 kW charger at a villa with the panel 10-15 metres away usually lands at 1,000-2,000 EUR with installation and VAT. The unit itself is the smaller part; most of the money goes on cable, protections in the panel, the trench and labour. The exact price comes after a site visit.

Five things push it up: a long route or a trench through paving and lawn; a detached garage; needing to upgrade the supply or move to three-phase; a second point; and costly reinstatement of finishes (natural stone, parquet, a facade). In an Eixample flat with a space in a shared garage, the heavy part is agreeing the route and working along common cable trays, not the charger.

Ask for separate lines in the quote: the unit, the circuit and protections, trench and reinstatement, CIE paperwork, power increase. If you see a single figure for "charger installation", you cannot compare offers.

Which mistakes cost the most?

The costliest mistake is remembering the charger after the paving, stone and landscaping are done. Second: connecting the charger to a shared garage line, with no circuit and no protection of its own. Third: fitting 22 kW at a villa with a single-phase supply when the car only takes 11. Fourth: not checking whether the contracted power holds in the evening and finding out when the main breaker trips mid-charge.

A separate case for non-resident owners: the car sits in the garage for weeks. Plan remote monitoring of the line and the charger through an app so you hear about an outage before you arrive. For villas with backup power, decide whether the charger should work during a grid cut. Usually not: you do not want to feed the car from the battery that the alarm and pumps depend on.

How does BCN YARD plan EV charging in a renovation?

If you are renovating a flat or a house, the cheapest time to settle EV charging is the electrical phase: ducts, a slot in the panel and the power level are planned from the start, with no need to open finished surfaces. We run projects in Russian and Spanish with one person responsible for the site, and the electrical work is done by a vetted registered installer. We size the power and the scheme with them after the site visit and measurements; the price is fixed in the quote before work begins, and payment is staged under contract.

If you only need the charger, with no renovation, write to us: we reply within an hour and tell you whether a visit is needed. For a flat in a community building we prepare the notice pack in advance: the cable route sketch and the installer's details.

Frequently asked questions

Can I install a charger if a neighbour in the community objects?

For an individual garage space in Catalonia, article 553-36.3 of the Codi civil de Catalunya only asks you to send the community the technical project 30 days in advance and the certificate when finished; neighbours' approval is not required. Within that period the community may propose a reasonable alternative, but if it does not carry it out within two months you can install yours, as long as the route does not affect common elements. Confirm with the administrador before ordering.

What charger is enough for a villa with one car?

Usually 7.4 kW single-phase: a car with about 60 kWh charges overnight. If the house has a three-phase supply, you can choose 11 kW. Under ITC-BT-52 a single-phase C13 circuit is capped at 9,200 W; more only if the designer justifies it.

Does the charger need its own circuit or panel?

The circuit must be dedicated: for a single-family house ITC-BT-52 requires an exclusive charging circuit (C13) with its own 30 mA class A residual-current breaker and a C-curve breaker. A separate panel is not always needed; space in the existing one is often enough.

How much does a charger cost at a villa?

A rough guide for 7.4 kW with the panel 10-15 metres away: 1,000-2,000 EUR with installation and VAT. A long trench, a detached garage, a power upgrade or a three-phase connection push it up. The exact figure comes from the quote after a site visit.
