Local proof: hometown shop, hometown permits
Historic Craftsman and Victorian homes near downtown and Franklin Street often need a panel and service evaluation before a transfer switch is installed — original fuse boxes and undersized 100-amp services still show up. Prairie Path and post-war ranch streets more often need enough kW for furnace, sump, and a finished basement. Newer construction toward Gary Avenue and Carlton Farms / Brynwood usually already has 200-amp service but higher continuous loads (two HVAC systems, electric range, EV circuit) that change the sizing conversation.
Because our shop is at 805 W Liberty Dr, Wheaton, IL 60187, assessments and follow-up inspections do not wait on a truck coming from two counties away. We already work with the City of Wheaton building department on permitted mechanical and electrical jobs every week.
City of Wheaton permits and setbacks
Permanent standby generators need City of Wheaton approval. Setbacks from lot lines, openings, and air intakes matter; so does clear access for service. We pull the permits, meet the inspector, and include that coordination in the project — not as a surprise line item after the pad is poured.
Electrical work is performed under licensed authority, including Chicago Supervising Electrician ECC-94505 where that credential applies. Gas-side work uses our plumbing entity and plumber licenses (055-044076 / 058-197647) when required.

Wheaton generator installation FAQs
Are you really based in Wheaton?
Yes. Headquarters is 805 W Liberty Drive. Generator assessments and installs start from this shop.
Do you install Generac generators?
Yes. We are Generac-capable and can also recommend other leading standby brands when they fit the load and fuel better.
Does the City of Wheaton require a permit?
Yes for permanent standby installs. We handle building and related inspections as part of the job.
How is sizing done for a Wheaton home?
We list the circuits and appliances you want online during an outage, check the panel, and recommend kW from that list — not from square footage alone.
How long does a typical install take?
About 1–2 days of on-site work after permits and equipment are ready. Permit timing follows the City schedule.
Can the same company do the gas line and the electrical?
Yes. That is why homeowners hire OneStop Pro for standby installs instead of juggling two contractors.
Do you offer maintenance after installation?
Yes. Annual service (oil, filters, battery, load test) keeps the unit ready for the next outage. Ask about the Home Maintenance Program.
