EV CHARGER INSTALL ESTIMATING.

## EV Charger Estimating in Houston Moves Fast — Your Bids Should Too Houston is the largest city in Texas and one of the fastest-growing EV markets in the South. CenterPoint Energy's service territory covers most of the metro, and the utility's EV infrastructure rebate programs have pushed residential and commercial charger installs to record volumes. That demand is real, but so is the competition among licensed electricians chasing the same commercial fleets, apartment communities, and single-family retrofits. Winning a bid here comes down to two things: knowing your actual cost exposure and getting a professional estimate in front of the customer before anyone else does. --- ### What Makes EV Charger Estimating Different in Houston **Load calculation complexity.** Every Level 2 charger install starts with a panel assessment. Houston homes built before 2000 frequently have 100A or 125A service — not enough headroom for a 48A dedicated EVSE circuit without a panel upgrade. You need to quote the upgrade or document why it is not needed. Estimate.Pro's EV workflow prompts you to log existing service size, available breaker slots, and wire run distance from the panel to the proposed charger location, so nothing gets missed. **NEC Article 625 compliance.** Texas adopts the National Electrical Code, and Article 625 governs EV charging systems. Houston's jurisdiction — primarily the City of Houston Permit Center or Harris County — requires a permit for any hardwired EVSE. Your estimate needs to account for the permit fee, a rough-in inspection, and a final inspection. Missing those line items is how margins disappear on a job that looked profitable on paper. **Commercial and multi-family complexity.** Houston's commercial real estate boom means a significant share of local EV installs are 20- to 100-port parking garage projects. Those bids require conduit runs, subpanel sizing, demand management controllers, and sometimes utility coordination for a new transformer or secondary service. Estimate.Pro lets you build itemized scopes at that scale without starting from a blank spreadsheet. **Heat and conduit considerations.** Houston's climate means outdoor conduit and equipment selection matter. Liquid-tight flexible conduit, NEMA 4X enclosures on exterior installs, and UV-rated wire are not upsells — they are code-correct spec choices. Your estimate should line-item them. --- ### How Estimate.Pro Works for Houston EV Charger Installers **Walkthrough to bid in 8 minutes.** Use your phone camera to measure the service panel location, wire run path, and charger mounting wall. ONNX-assisted AR measurement runs on supported devices. On older phones, camera and photo measurements are flagged as estimates so you know what to verify on-site. **Scope-of-work generator.** After your walkthrough, the AI drafts a scope that includes existing service size, circuit size, conduit type, EVSE mounting spec, and permit line items. Edit anything before it goes to the customer. **Saved material cost workspace.** Store your Houston-area pricing for wire, conduit, NEMA boxes, and EVSE hardware. When CenterPoint or distributor pricing shifts, update once and every future estimate reflects it. **Free tier, no credit card.** Start building estimates today at no cost. Pro is $39 per seat per month. Elite at $79 per seat adds Stripe Connect invoicing with 0% platform fee and invoice exports — useful when you are billing a property management company or fleet operator on net-30 terms. --- ### Houston-Specific Workflow Notes If you are quoting a job inside the City of Houston limits, pull the current EVSE permit fee schedule from the Houston Permit Center before finalizing your estimate — fees are assessed per unit on multi-port commercial installs. For jobs in unincorporated Harris County, permits go through Harris County Engineering, and inspection scheduling can add a day or two to your timeline. Factor that into your project schedule line. CenterPoint's Make-Ready rebate program may offset some infrastructure cost for the customer. Knowing that before the sales conversation lets you position your bid more accurately and avoid getting shopped on a number the customer thinks they can reduce with a rebate they have not applied for yet. Estimate.Pro supports 25 trades. If you also do panel upgrades, solar interconnects, or generator installs, your estimating workflow carries over without switching tools. --- Build your next Houston EV charger estimate on Estimate.Pro.
