Yes — Done handles the full permitting and inspection process for commercial HVAC, plumbing, and electrical work in Denver and across the Front Range. Our licensed technicians know local code requirements, pull the necessary permits before work begins, and schedule inspections with the relevant jurisdiction so your project stays compliant from start to finish.
Why Permits Matter for Commercial Work
Commercial permits are not a formality — they are a legal requirement that protects your building, your occupants, and your business. Unpermitted work can trigger fines, force costly tear-outs, complicate insurance claims, and create liability exposure if something goes wrong. In Denver, the Department of Community Planning and Development (CPD) enforces permit requirements for most mechanical, plumbing, and electrical scopes, and inspectors look at both installation quality and code compliance.
At altitude — Denver sits at roughly 5,280 feet — code requirements for combustion equipment (furnaces, boilers, commercial water heaters) include specific adjustments for reduced oxygen levels. Our technicians are trained for this environment and size and install equipment accordingly, which matters when an inspector reviews the job.
What the Permitting Process Looks Like
Before any work starts, we identify the correct permit type for your scope — mechanical, plumbing, electrical, or a combination — and submit the application with the required project documentation. For larger commercial jobs, this may include equipment specifications, load calculations, or engineered drawings depending on the city or county jurisdiction. We track the application status and handle back-and-forth with the permit office so your project timeline stays on track.
Once work is complete, we coordinate the final inspection with the inspector, are present during the visit, and address any corrections on the spot or in a timely follow-up. You receive documentation showing the job passed inspection — important for your records, for tenant move-ins, and for future property transactions.
Jurisdictions We Work In
Denver metro commercial properties span multiple permitting jurisdictions — the City and County of Denver, Aurora, Lakewood, Arvada, Westminster, Thornton, Englewood, Littleton, and others each have their own permit offices and inspection schedules. Done works across these jurisdictions regularly. We know which offices have online portals, which require in-person submittals, and how to follow up when permits take longer than expected — all of which saves you time and frustration.
Trades We Pull Permits For
- HVAC: rooftop units, split systems, packaged systems, boilers, commercial heat pumps
- Plumbing: water service lines, drain and sewer work, commercial water heaters, backflow prevention
- Electrical: panel upgrades, subpanels, EV charging infrastructure, lighting, outlets, and service upgrades
- Combination scopes: tenant build-outs, remodels, and new construction involving multiple trades
What to Have Ready When You Call
To give you an accurate timeline and estimate, it helps to know the property address and jurisdiction, the scope of work (what’s being replaced or installed), whether this is a tenant space or owner-occupied building, and any deadlines tied to a lease, opening date, or insurance requirement. The more detail you can share upfront, the faster we can move through the permitting process.
How Inspections Work and What Happens After
After the work is complete, the assigned inspector visits the site to verify the installation meets code — checking materials, installation methods, clearances, and safety devices depending on the trade. If the inspector notes any correction items, Done addresses them and schedules a re-inspection. We stay involved through the process until you have a passed final inspection in hand. Some property managers and owners aren’t on-site during inspections; Done can be the point of contact so you don’t need to be there.
Passed inspection documentation matters beyond compliance — it’s part of the building’s record, can affect property insurance, and is often required as part of lease agreements or property sales. We provide a copy of the permit card and any inspection sign-off documentation for your records.
