Main Electrical Box for All Units: Utility, HOA or Owner?

The Short Answer

The main electrical box that feeds every unit is usually the association’s, not the utility’s and not yours. The utility’s ownership stops where its wires connect to the building. The meters are the exception: the utility owns those, even though they sit in the association’s equipment.

• The utility (SCE, Con Edison or your local company) owns: the line from the street, the transformer that serves the building, and the electric meters.
• The association usually owns: everything after the connection point. That means the main switch or switchboard, the meter bank, each meter socket, the feeders that run to the units, and the electrical room or transformer pad. This equipment serves everyone, so declarations almost always make it a common element.
• You usually own: your unit’s breaker panel and the wiring inside your unit. Our guide to electrical panels and wiring covers that part.
• Rule of thumb: equipment that serves more than one unit is usually the association’s. Equipment that serves only your unit is usually yours. Your declaration can change either.
• Who pays: if the association’s equipment fails, all owners pay through dues, reserves or a special assessment. You pay alone only if the declaration assigns that piece to your unit, or you caused the damage.

Where the Utility’s Ownership Ends

Every utility names the point where its wires meet the building’s. Before it, the equipment is the utility’s. After it, the equipment is the property owner’s, except for the meters. Here is how the two largest utilities in the search queries define it.

Southern California Edison. SCE’s Rule 16 is a tariff filed with the California Public Utilities Commission. It defines the Service Delivery Point as the place “where SCE’s Service Facilities are connected to either Applicant’s conductors or other service termination facility” (SCE Rule 16, definitions). SCE owns, operates and maintains its Service Facilities: service conductors, service transformers and SCE-owned meters (Rule 16, sections A.2 and A.3). Past that point, the customer must “furnish, install, own, maintain, inspect, and keep in good and safe condition” the equipment SCE requires. The rule lists “meter sockets, meter and instrument transformer housing, service switches, circuit breakers, fuses” (Rule 16, section D.1.c). That list sits in section D, which covers new service extensions, but it describes equipment the customer goes on owning.

Con Edison. Con Edison’s specifications book (the “Blue Book”) calls the handoff the Point of Service Termination: “the point at which the company terminates its service lateral and the customer’s wiring begins” (Blue Book, Section II). It says “the customer/contractor has the responsibility to maintain all wiring and equipment in a safe and operating condition” (Blue Book, Section I). Con Edison’s outage page says it owns the service wire from the street and the meter. The meter pan, entrance cable and weatherhead are the customer’s (Con Edison, what we repair after outages).

In a condo building, the “customer” for the shared service equipment is the property owner. For common elements, that is the association.

Other utilities use their own rules and their own names for this point (“point of delivery”, “service point”, “demarcation point”). Most draw the line in a similar place, but check your utility’s service rules or electric service requirements before you rely on this.

Who Owns What: Equipment by Equipment

About transformers. If the gray or green box on a concrete pad is an SCE transformer, SCE owns and maintains the transformer itself. The association still owns the pad and any protective posts or walls SCE required (Rule 16, D.1.g(2)). If the transformer sits in a room or vault inside the building, the room or vault belongs to the property owner and must meet SCE’s specifications for access, ventilation and drainage (Rule 16, D.1.g(4)). Some large buildings own their own transformers. Ask the utility or look at the building’s electrical drawings.

In Con Edison territory, building transformers usually sit in vaults under the sidewalk. For 265/460-volt service, Con Edison also needs a network compartment inside the building (Con Edison, Transformer Vault Placement and Space Requirements (2006 guide)). That guide does not say who maintains each piece, so ask Con Edison.

What the Declaration and State Law Add

The utility’s rules decide where its ownership ends. Your declaration decides how the rest is split between the association and the owners.

1. Find the unit boundary. Most declarations make the unit end at the interior surface of the walls. Equipment in a shared electrical room is then outside every unit, and so a common element. See unit boundaries.
2. Find the maintenance clause. Search the declaration for “electrical”, “utility”, “meter” and “conduit”. Some say the association maintains everything up to the unit’s panel. Others say it maintains lines that serve more than one unit.
3. Check for limited common elements. In townhome-style condos, each home may have its own meter base on its own wall. Some declarations make that a limited common element charged to that unit. See limited common elements.

Florida. “Maintenance of the common elements is the responsibility of the association, except for any maintenance responsibility for limited common elements assigned to the unit owner by the declaration” (Fla. Stat. 718.113(1)). See Florida condo law.

California. Unless the declaration says otherwise, or the utility must do the work, the association must make the repairs needed to restore interrupted electrical service that begins in the common area. That holds even when the problem extends into a unit. The board must start the repair process within 14 days of the interruption. If reserves are short, it may get competitive financing from a financial institution (per Civ. Code 5735) and levy an emergency assessment without a member vote. Before it borrows, it must pass a resolution with written findings (Civ. Code 4775(a)(2) and (b)). These duties do not apply when a declared federal, state or local emergency materially affects the association’s ability to act (4775(e)). See California condo law.

A worked example. A 24-unit building’s 1980s meter bank is found failing by an electrician, and the electrician’s bid to replace it is $72,000. (This is an illustrative number; real bids vary widely.) The meter bank is a common element, so it is a common expense. Reserves cover $30,000, and the $42,000 gap is assessed by percentage interest. A unit with a 4.0% interest owes $1,680. A unit with 3.5% owes $1,470. The utility pays nothing toward the new bank, but it supplies and sets the new meters.

If the Box Is Damaged, Unlocked or the Power Fails

The power is out

Work out how far the outage reaches. That tells you whom to call.

If the meter pan or entrance cable is damaged, Con Edison says you “will need to work with a licensed electrician to repair or replace it before we can restore your service” (Con Edison). In a condo, the association hires that electrician for shared equipment.

The box or room is unlocked

An open electrical room is a safety problem, and fixing it is usually the association’s job. Report it in writing to the manager with the date, the location and a photo of the open door or panel. Do not open covers or touch anything inside.

In SCE territory, Rule 16 lets the property owner use “a SCE-approved locking device” to keep people away from rooms that hold SCE equipment, as long as SCE keeps safe access (Rule 16, A.11). SCE seals its meter rings and enclosure covers. Only SCE’s authorized employees may break those seals, except in an emergency (Rule 16, D.1.f). If you see a broken seal or a cover hanging open on a live part, report it to the utility too.

The box is damaged

1. Photograph it and note the date. If it is sparking, buzzing, hot or smells burned, call 911 first.
2. Tell the manager in writing. In California, the 14-day clock to start repairs runs from the interruption of service (Civ. Code 4775(b)(1)).
3. Do not hire your own electrician for shared equipment. Work on a common element usually needs the board’s approval. Meter seals may only be broken by the utility.
4. Call your HO-6 insurer if food, appliances or your unit were damaged. Ask whether the association’s master policy covers the equipment itself.
5. Ask for the records if the association refuses. Request the declaration, the electrical repair history and the reserve study. Our guide on requesting HOA documents has a letter, and repair disputes walks through the next steps.

Buying? Ask whether the main service equipment is in the reserve study and when it was last replaced. Original equipment in an older building can lead to a special assessment.

Frequently Asked Questions

Who is responsible for the main electrical box of all units in a condo?

Usually the association. The box (the main switch, meter bank and meter sockets) sits after the point where the utility's line ends, so the property owner owns it. It serves every unit, so declarations almost always make it a common element. The utility still owns the meters inside it. Check your declaration's maintenance clause to confirm.

Who is responsible for the electrical box, Edison or the HOA?

SCE owns the service line, the transformer and the meters. Under SCE's Rule 16, the property owner owns and maintains the meter sockets, service switches and breakers past SCE's Service Delivery Point. In a condo, that is usually the HOA. If only the meter itself is bad, SCE replaces it.

The electrical box in our complex is unlocked. What should I do?

Do not open or touch it. Report it to the property manager in writing with a photo and the date, and ask when it will be secured. Securing a common-area electrical room is usually the association's job. If the room holds SCE equipment, Rule 16 (A.11) calls for an SCE-approved lock so SCE crews can still get in. If a utility seal is broken or a live part is exposed, also call the utility.

Is a building transformer the responsibility of the building owner?

Usually not the transformer itself. Under SCE's Rule 16, SCE owns and maintains the transformer, while the property owner provides and maintains the pad, the protective posts, and any transformer room or vault. Some large buildings own their own transformers, so ask your utility or look at the building's electrical drawings.

Who pays if the power fails in the whole condo building?

If the fault is on the utility's side (the street line or the transformer), the utility repairs it at no cost to you. If it is in the building's main switch or meter bank, the association repairs it and all owners share the cost by their percentage interest. In California, the board must start the repair process within 14 days of the interruption, unless a declared emergency applies.
