Interior Demolition in Boulder

Do you need a permit for interior demo in Boulder?

It depends on what the work touches — and that is the honest answer, not a dodge.

Pulling non-structural finishes — cabinets, countertops, flooring, a non-load-bearing partition that has no wiring or plumbing in it — is frequently treated as cosmetic work. Once the scope touches anything structural, electrical, plumbing, or mechanical, a permit is generally in play. Moving a wall that carries load, pulling out a tub and the supply lines behind it, relocating circuits, cutting into ductwork: that is permit territory.

The decision belongs to Boulder Planning & Development Services. We will tell you plainly which side of the line we think your job falls on, and when it is close, we call before we cut. A demo that gets red-tagged halfway through costs far more than the permit would have.

The part most people have never heard of

Before the permit question, there is the testing question, and it catches almost everybody.

Colorado's asbestos rule (CDPHE Regulation 8) applies here like it does statewide: for a single-family home, disturbing more than 32 sq ft, 50 linear ft, or a 55-gallon drum's worth of suspect material triggers an inspection requirement before work starts.

That threshold is smaller than people expect. One room of old sheet vinyl, a popcorn ceiling, or the joint compound in a single wall can reach it. If the building went up before the mid-1980s, assume suspect material is in play until a test says otherwise.

There is a second layer on older homes. Federal lead rules (the EPA's RRP rule) govern work that disturbs painted surfaces in housing built before 1978 — and demolition counts. That work has to be performed by an EPA Lead-Safe Certified firm. We do not perform pre-1978 residential demolition. What we do is tell you straight that the rule exists, so you are not finding out from an inspector.

What we actually do in Boulder

We take on post-1978 residential interiors and commercial, office, retail, and tenant-improvement strip-outs — the non-hazardous demolition itself. Kitchens and baths stripped to studs. Flooring, drywall, ceilings, built-ins, fixtures. Commercial spaces cleared for the next tenant.

And because Frontier runs its own bins and hauling, the debris does not become your problem. The container shows up when the crew does, and it leaves when the work is done.
