Painting in Louisville, CO

Painting is one of the few exterior projects in Louisville that does not need a City permit on its own, but that does not mean every painting job is a simple color decision. The federal lead-safe renovation rule reaches into older Louisville homes, historic-landmark properties have their own exterior-change process, and any painting job that turns into drywall repair or a larger remodel can cross back into permitted territory. This page separates what is and is not required.

Exterior House Painting Does Not Need a Louisville Permit

Louisville’s permit-requirements table lists “Painting – Exterior House” with no permit required. That is a straightforward line item on the City’s official list, and it applies to ordinary repainting of an existing exterior. A separate, stand-alone exemption specifically for interior-only painting was not listed the same way; interior work that is part of a broader remodel, such as new drywall or a room reconfiguration, falls under the City’s residential remodel permit instead of being treated as paint alone.

In practice, the distinction is what the work actually touches. Recoating existing siding, trim and previously painted surfaces stays outside the permit system. Once the scope adds drywall replacement, structural change, or new electrical or plumbing work alongside the paint, that portion of the job needs its own permit even if the finish coat is still just paint.

Lead-Safe Rules for Homes Built Before 1978

The federal EPA Renovation, Repair and Painting Rule applies to renovation work that disturbs painted surfaces in a home, child-care facility or school built before 1978. Covered work is defined by size: more than 6 square feet of painted surface disturbed per interior room, more than 20 square feet of exterior painted surface, or any window replacement or demolition of a painted surface. Above those thresholds, the work has to be performed by an EPA-certified firm using EPA-certified renovators and lead-safe work practices; minor repair and maintenance at or below the thresholds is exempt.

Colorado does not run its own EPA-authorized version of this program, so RRP certification and enforcement for Colorado firms comes directly from the EPA rather than a state agency. The Colorado Department of Public Health and Environment separately licenses lead abatement, which covers full removal or encapsulation projects aimed at eliminating lead hazards — a different category from ordinary renovation-driven paint disturbance. Before scraping or sanding old paint on a pre-1978 Louisville home, the age of the structure and the scope of surface disturbed both need to be confirmed.

Historic and Association Review Sit Outside the Permit System

Louisville’s historic preservation program covers landmarked properties, and any exterior change to one of them needs an Alteration Certificate; the City’s guidance names additions, garages and fences as covered changes. Whether a color-only repaint on a landmarked home triggers that same review is not stated on the City’s page, so a landmarked property’s owner should confirm that question with Planning before selecting a new exterior color.

Homeowners’ association covenants are a separate matter entirely. The City does not review projects for compliance with private HOA rules, so an HOA’s own color-approval process, where one exists, has to be checked directly with the association rather than assumed to be covered by the absence of a City permit.

What a Repaint Cannot Fix on Its Own

Peeling, blistering or repeated cracking on exterior trim or siding is usually a sign of a moisture, adhesion or movement problem underneath the paint, not just a finish issue. Addressing the underlying cause, whether that is failed caulking, a leak, or wood that needs repair, comes before a new coating goes on. A fresh coat over an unresolved condition tends to fail again quickly, and if the repair itself involves new drywall, siding or trim replacement, that portion of the work may need its own permit even though the paint layer does not.

We treat the paint scope and any repair scope as separate line items from the first estimate, so it is clear which part of the job is unregulated finish work and which part, if any, needs to go through Building Safety before the color goes on.

How We Sequence a Louisville Painting Project

We start by confirming the home’s construction date, since that determines whether the EPA lead-safe rule applies, and by identifying any drywall, trim or siding repair that needs to happen before the surface is ready for paint. Repairs that trigger their own permit are separated out and scheduled through Building Safety, while the painting itself proceeds without a City permit once the substrate is sound.

For a pre-1978 home where the disturbed area crosses the EPA thresholds, containment, cleaning and lead-safe work practices are built into the schedule from the start rather than added after prep work has already begun. For a landmarked property, we confirm with Planning whether the intended color change needs review before finalizing the palette.

Common Questions

Do I need a permit to paint my house in Louisville?
No, not for ordinary exterior repainting. The City’s permit list states that “Painting – Exterior House” does not require a permit. If the project also includes drywall, siding or structural repair, that separate work may need its own permit.

Does my home’s age matter for a repaint?
Yes, if it was built before 1978. The federal EPA Renovation, Repair and Painting Rule requires lead-safe work practices by an EPA-certified firm once the disturbed surface exceeds 6 square feet indoors per room or 20 square feet outdoors, or the work involves window replacement or demolition of painted surfaces.

Is Colorado’s lead rule different from the federal one?
Colorado does not operate its own EPA-authorized RRP program, so RRP certification and enforcement come directly from the EPA. CDPHE separately licenses full lead abatement projects, which is a different category from routine renovation-driven paint disturbance.

Does a historic designation affect a color change?
It can. Exterior changes to a Louisville landmarked property need an Alteration Certificate, and whether a paint-color-only change counts is not stated on the City’s page, so we confirm that with Planning before a landmarked home’s color is finalized.

Talk to Us About Your Project

Tell us the age of the home, the surfaces you want painted, and any peeling, staining or cracking you have noticed. We will identify whether the EPA lead-safe rule applies, separate any repair work that needs its own permit from the paint itself, and confirm a historic-review question if the property is landmarked.
