Garage vs outdoor — where to put the charger.
Garage installs are simpler, cheaper, and more protected. Outdoor installs are necessary for some properties — driveway parking, detached carports, ADUs — and add $400-$900 for weatherproofing and mounting.

Garage installs are the default — cleaner conduit routing, charger protected from weather, easier mounting. Outdoor installs cost $400-$900 more for weatherproof conduit, weather-rated charger, and mounting structure. Both work fine in Marin's climate when done correctly; the choice depends on where you actually park.
01Garage install — typical setup.
Garage installs are what we do most often in Marin — about 75% of installs end up in garages. Typical scope: panel located in garage or nearby utility room, EV charger mounted on garage wall within 6-8 feet of the parking spot, short conduit run (often 10-25 feet) with exposed EMT or wall-fished routing. Total install runs the lower end of typical pricing: $1,400-$2,400.
Garage interior gives you weather protection (charger sits indoors, no exposure to rain or marine salt air that's harsh on outdoor electrical), easier conduit routing (don't need to route through exterior walls or weatherproof junctions), and less expensive hardware (basic indoor-rated chargers cost less than NEMA 4-rated outdoor units, though most modern chargers are NEMA 4 anyway).
02Outdoor install — what's different.
Weatherproof conduit + boxes
Outdoor conduit runs use EMT or PVC rated for outdoor exposure, with proper sealed junction boxes. Costs marginally more ($80-$180 in materials) but mostly affects labor — outdoor conduit is more time-consuming to route cleanly.
NEMA 4 / outdoor-rated charger
All modern Level 2 chargers (Tesla, Wallbox, ChargePoint) are NEMA 4 rated, so this isn't a hardware cost differentiator anymore. Cheap unbranded chargers may not be — confirm rating before outdoor install.
Mounting structure if no wall available
Driveway installs without an exterior wall need a pedestal or post mounting. Costs $300-$600 for the mounting hardware plus install labor. Most installers prefer wall mounting where possible (more secure, less prone to vehicle impact).
Sunlight and physical protection
Direct sun degrades charger plastic over time. North-facing or sheltered locations preferred. Some Marin properties add a small roof or cover over outdoor chargers — adds $400-$900 for cover construction but extends charger life significantly.
03Marin climate considerations.
Marin's climate is mild but has specific considerations for outdoor electrical. Marine salt air (particularly Mill Valley, Tiburon, Sausalito coastal areas) accelerates corrosion on outdoor electrical hardware — we use stainless or aluminum fittings instead of standard steel where applicable. Heavy winter rain plus occasional driving wind requires proper conduit sealing and well-mounted weatherproof junctions.
Summer sun exposure is meaningful in inland Marin (Novato, parts of San Rafael) — direct south-facing outdoor charger installations should consider a small shade structure or relocate to a sheltered location. We've seen chargers with cracked plastic enclosures from 5-7 years of direct sun in inland sites; protected installs last meaningfully longer. None of this prevents outdoor install; just informs how to do it well.
Common questions.
Is outdoor EV charger installation safe in the rain?
Yes, when properly installed. All modern Level 2 chargers carry NEMA 4 weatherproofing (rated for rain, splashes, and minor immersion). The charger and connector are designed to be plugged into the vehicle in light rain without issue. Heavy rain isn't ideal — water can drip into the connector during plug-in — but doesn't create safety hazards. The conduit and junction boxes must be properly sealed during install; that's where outdoor installs go wrong if done by non-EV-specialty electricians.
How much more does an outdoor install cost?
Typical Marin outdoor install runs $400-$900 more than equivalent indoor garage install. Cost drivers: weatherproof conduit and sealed junction boxes, longer or more complex routing (often outdoor installs are farther from panel than garage installs), pedestal/post mounting if no exterior wall available, and the labor premium for working in weather conditions. Hardware cost is generally not a differentiator — modern chargers are NEMA 4 either way.
Can I install the charger in my driveway with no garage?
Yes, with pedestal mounting and weatherproof installation. We've done many driveway installs in Marin — typical scope: pedestal mounting (4-foot bollard with weatherproof box), conduit run from house panel to pedestal location (often 30-60 feet), full NEMA 4 weatherproofing. Total typical cost $2,400-$3,600 for driveway pedestal install. The charger is exposed to weather but works fine; we recommend a small shade structure for inland Marin properties to extend hardware life.
Will my charger be damaged if my car bumps into it?
Possibly, depending on impact. Wall-mounted chargers at typical mounting height (48-52 inches) are above bumper height and usually safe from car contact. Pedestal-mounted chargers in driveways are more vulnerable — most pedestals include a bollard for impact protection, but a serious impact (someone backing up at speed) can damage the charger or pedestal. For high-traffic driveways or commercial-style multi-tenant settings, we sometimes recommend additional bollard protection beyond the standard pedestal.
How do you handle pricing — flat fee or hourly?
Both, depending on scope. Routine service calls and predictable scope (panel replacement, EV charger install, transfer switch install, fixture replacement) are flat-fee quoted up front. Diagnostic visits and emergency scope are hourly because we don't know what we'll find. Either way, you get a written quote before work starts on anything significant, and we don't proceed beyond the quote without your sign-off.
How quickly can you schedule?
Depends on scope and season. Emergency dispatch: same-day across Marin County (1-3 hours business hours, 1-4 hours after-hours). Same-day standard service: 3-6 hours from call when capacity allows; otherwise next business day. Scheduled service work: 1-3 weeks typical. Larger projects requiring permits and PG&E coordination: 4-12 weeks depending on scope. We're upfront about timeline at the quote stage.
What warranty do you offer on work?
Our standard residential warranty: 2 years on labor, manufacturer warranty on parts (varies by product — typically 1-10 years). Major installs (panels, generators, EV chargers) often have longer manufacturer warranties (5-10 years). If there's an issue with our work in the warranty period, we come back and fix it at no cost. We also stand behind work past warranty — repeat customers and referrals matter more than a transactional fix.
Are you licensed and insured?
Yes. California State License Board C-10 Electrical Contractor #989290, in good standing. Carry general liability insurance and workers' compensation insurance as required by California law. Bondable on projects requiring it. Happy to provide proof of insurance to clients or property managers on request. License lookup: cslb.ca.gov.
