Why Park Cities homes are outgrowing their original panels
Most of the original homes in Highland Park and University Park were built with 100A or 150A services — sized for a 1960s kitchen, a single A/C condenser, and incandescent lighting. A modern luxury remodel routinely adds an induction range (40–50A), a steam oven, a wine column, a 60A EV charger, a heat-pump pool heater, and a second A/C stage. The math stops working long before the breaker physically fits. We perform a written NEC Article 220 load calculation that adds your existing appliances, planned additions, and a future-EV allowance. When the calc lands above 80% of service capacity — the NEC threshold for safe continuous load — we recommend the upgrade in writing so your insurer, designer, and architect are all working from the same number.
