Permit Thresholds

Brighton permit thresholds

Brighton, Colorado (City of Brighton building department) requires a building pe

Any owner or authorized agent who intends to construct, enlarge, alter, repair, move, demolish or change the occupancy of a building or structure, or to erect, install, enlarge, alter, repair, remove, convert or replace any electrical, gas, mechanical or plumbing system...§R105.1

Code reference

This is codified in Brighton Municipal Code (BMC) Chapter 15 (Buildings and Construction), particularly Article 15-28 (International Residential Code adoption and amendments).

Building

One-story detached accessory structures (e.g., sheds, playhouses) ≤ 200 sq ft floor area (zoning must still be met); retaining walls ≤ 4 ft high (footing to top); painting, papering, tiling, carpeting, cabinets, countertops, and similar finish work; prefabricated swimming pools < 24" deep; swing set

Electrical

Listed plug-and-cord temporary decorative lighting; replacement of a circuit breaker (same location/capacity); low-voltage wiring/devices (< 25 volts, ≤ 50 watts); minor repairs like changing bulbs or same-location fixture/outlet replacement.

Notes on exemptions and triggers

The FAQ lists slightly varying shed thresholds (e.g., < 120 sq ft in one place); the dedicated permit guide (200 sq ft) is the more specific reference.

Code reference

Any structural alteration, enlargement, or repair affecting the structure generally triggers a permit under the broad “alter/repair” language of R105.1 (no separate valuation-based threshold or explicit “structural trigger” list beyond this).

Use tax/fee basis

Use tax is 3.75% applied to 50% of the project valuation (materials + labor).

Codes are amended regularly — verify current requirements with **The City of Brighton (specifically its Community Development/Building Division) issues residential building permits.
