Mobile Home Demolition Permits in Boulder County: What Actually Has to Happen First

The Asbestos Inspection Comes Before the Permit

Most people think the permit is step one. In Colorado, it is not. Before any demolition permit is issued, a certified asbestos inspection has to be completed on the structure being torn down.

Here is the part that surprises homeowners: there is no age exemption. It is easy to assume only old mobile homes need testing, but Colorado’s rule requires the inspection regardless of when the home was built. Older units placed before the 1980s are more likely to actually contain asbestos in siding, floor tile, or ceiling texture, but the inspection itself is required either way.

Here is how the asbestos step actually works:

• A CDPHE-certified inspector visits the home and collects samples from suspect materials such as siding, vinyl floor tile, and textured ceilings.
• Samples go to a lab, and results usually come back within a few days.
• If asbestos is found and it is friable, it must be removed by state-certified abatement workers, under a separate state permit, before demolition can begin.
• If no asbestos is found, or it is non-friable and can stay in place, you get the signed report needed to move the permit forward.

A full-demolition asbestos survey in Colorado typically runs somewhere between $350 and $2,500, depending on the size of the home and how many samples are needed. A DIY test kit will not work here, the permit requires a report from a certified inspector, not a home kit.

One thing worth knowing: Boulder County’s health department used to regulate asbestos testing directly. That has changed, it is now handled through the building permit process and the state (CDPHE). If you want to confirm the current process or need help lining up a certified inspector, that is exactly the kind of thing we walk homeowners through.

Utility Disconnects: The Real Timeline Bottleneck

The slowest part of a mobile home teardown almost always happens before demolition day, not during it. A live gas line or a hot electrical panel is a genuine hazard, so the utilities have to be safely disconnected before the work starts, and each one runs on its own schedule.

Here is what typically has to be handled:

• Gas and electric disconnected by Xcel Energy, with written confirmation the meter is pulled.
• Water shut off at the curb stop, confirmed by the local water provider.
• Sewer capped, or the septic tank properly pumped and abandoned if the home is not on city sewer.
• Any propane tank removed by the supplier before demolition day.

The honest advice: start making utility calls the same week you decide to demolish, not the week you plan to start. Utility crews often need several business days to a couple of weeks to get scheduled, and that wait is the single most common reason a mobile home teardown slips behind. Keep every disconnect confirmation in one place, you will need that paperwork for the permit.

Older Homes May Trigger an Extra Review

One more thing that catches people off guard in the City of Boulder: a structure over 50 years old can trigger a separate Historic Preservation Demolition Review, on top of the standard demolition permit. It is a separate process from the permit itself, and it is meant to flag older buildings before they come down.

Not every mobile home hits that mark, but older units in long-established parks sometimes do. You can check a building’s year of construction through the Boulder County Assessor’s property records. If your unit is close to that 50-year line, it is worth confirming before you set a demolition date, so the review does not become a surprise delay.
