--- title: Apartment and Multi-Unit Building Electrical Upgrades: Who Manages What description: Confused about who handles [av_keyword_plain] — the owner or the tenant? We break down the responsibility split clearly so no one pays for the wrong scope. url: https://fhrelectric.com/apartment-and-multi-unit-building-electrical-upgrades-who-manages-what date_modified: 2026-10-02 author: language: en_US --- If you own or manage a rental property in , questions about come up constantly — and the answers matter before anyone pulls a permit or touches a panel. Three tripping breakers, flickering lights in two units, and a tenant asking about an EV charger: that’s the exact scenario a property manager brought to us not long ago. Two other contractors had given him useless quotes with no scope breakdown. The real problem? Nobody had explained who owns which part of the system. Once that line is clear, everything else follows. ## The Responsibility Split — Laid Out Clearly The dividing line is the unit’s metering point. Everything upstream of the meter is the building owner’s responsibility. Everything downstream belongs to the tenant — or the unit owner, if the unit is vacant or owner-occupied. It’s that clean, and understanding it upfront saves everyone from expensive back-and-forth. ### Building Owner / Property Manager — Always Your Scope ![Licensed electrician inspecting a commercial distribution panel during an apartment building electrical upgrade inside a multi-unit utility room](https://fhrelectric.com/wp-content/uploads/2026/09/avathan-6ab63b4b7a67b.jpg "Apartment and Multi-Unit Building Electrical Upgrades: Who Manages What") - The utility service entrance and meter base(s) - The main distribution panel or switchgear feeding individual units - Common-area wiring: hallways, parking, laundry, lobby, exterior lighting - Subpanels in shared mechanical rooms - Shared EV charging infrastructure in parking areas - Feeder conductors running from the main panel to each unit’s sub-meter or breaker ### Individual Unit — Tenant or Unit Owner’s Scope ![Licensed electrician inspecting a commercial distribution panel during an apartment building electrical upgrade inside a multi-unit utility room](https://fhrelectric.com/wp-content/uploads/2026/09/avathan-6ab63b5857e7e.jpg "Apartment and Multi-Unit Building Electrical Upgrades: Who Manages What") - The unit’s breaker panel (downstream of their meter) - All branch circuit wiring, outlets, and switches inside the unit - Appliance circuits specific to that unit (washer, dryer, range) - In-unit smart devices or lighting upgrades - A personal Level 2 charger inside a private garage — though the feeder to that garage may still be the building owner’s > The meter is the dividing line. Everything the whole building shares is the owner’s responsibility. Everything a single unit consumes is that unit’s problem — but only after the meter. The most common misread we see in : owners assume a tripping breaker is a tenant’s appliance problem. In reality the issue is almost always upstream — an undersized 1980s 200-amp service feeding loads it was never designed to handle. If you’ve ever stared down a [panel that can’t keep up with modern loads](https://fhrelectric.com/should-you-repair-or-replace-your-electrical-panel-an-honest-guide/) and wondered whether repair or replacement makes more financial sense, the answer in a multi-unit building almost always leans toward full replacement — you’re buying headroom for tomorrow, not just fixing today. ## How We Scope and Execute a Multi-Unit Electrical Upgrade 1. **Load audit of the full building.** We calculate existing demand across all units and common areas to determine whether the service entrance needs upgrading — often from 200A to 400A. Not sure if your building needs that jump? Our guide on [when a property needs 400-amp service](https://fhrelectric.com/when-does-a-home-actually-need-400-amp-service/) is a solid starting point. 2. **Thermal imaging inspection of the main panel.** Infrared scans identify hot spots — overloaded breakers, loose lugs, failing connections — that a visual check misses entirely. This is also where we routinely find [double-tapped breakers](https://fhrelectric.com/what-a-double-tapped-breaker-is-and-why-its-not-a-minor-issue/) added as shortcuts by previous contractors. 3. **Permit and utility coordination.** We pull the necessary permits and coordinate with the local utility for the service-side work, scheduling around tenant occupancy to minimize disruption. 4. **Panel replacement and circuit documentation.** New panel, properly sized breakers for each unit feeder, labeled circuits, clean wiring — no shortcuts, no deferred issues pushed downstream. 5. **Final inspection and written record.** Every circuit, its rating, and what it serves — documented and handed to you. That paperwork matters for insurance, future sales, and any contractor who works on the building after us. Cost ranges for a full multi-unit service upgrade in typically run from around $4,500 for a straightforward panel replacement on a smaller building to $18,000–$25,000+ for a full service entrance upgrade with new distribution gear on a larger property. Scope drives the number — which is exactly why the load audit comes first. Per the [National Electrical Code requirements for multi-family dwellings](https://www.nfpa.org/codes-and-standards/nfpa-70-standard-development/70), proper load calculation and panel sizing are not optional — they’re code. Worth noting: if your building has aluminum branch-circuit wiring — common in construction from the late 1960s through the 1970s — address it at the same time as any service upgrade. A new panel feeding old, higher-risk conductors is a problem you’ll face again at renewal time with your insurer. The property manager we mentioned at the start? We upgraded his service entrance to 400 amps, replaced the distribution panel, ran a dedicated feeder for shared EV charging in the carport, and had everything inspected and closed out in under two weeks. No more tripping breakers. No more angry tenant calls. That’s what done right actually looks like — and you can picture the same result for your building.
