Brighton full kitchen remodel permits — the key details

Brighton requires a building permit anytime you move, remove, or enlarge wall openings in a kitchen—even if the wall is non-load-bearing. The city's 2021 code mandate (aligned with IRC R602) requires a structural engineer's letter or a pre-calc beam schedule for any load-bearing wall removal, and this must be stamped and submitted before plan review begins. Brighton's Building Department will reject incomplete framing plans on first review; expect a 2–3 week turnaround for plan corrections. The frost-depth requirement in Brighton (30–42 inches in the town proper, up to 60+ in the foothills) affects kitchen work indirectly if you're also doing foundation or exterior wall work, but interior kitchen remodels don't typically involve frost-depth compliance unless you're moving an external wall or adding an exterior kitchen egress window. Load-bearing walls are the single largest source of permit rejections in Brighton kitchens because many homeowners and small contractors underestimate the city's engineering scrutiny—you cannot simply remove a wall above the sink or stove without proof of load transfer.

Plumbing relocation in kitchens must include a venting diagram showing all drain lines, trap arms (which must slope 45 degrees downward toward the main drain), vent lines (vertical or near-vertical), and distance from trap weir to vent inlet. Brighton requires a separate plumbing sub-permit, filed by a Colorado-licensed plumber; homeowners cannot pull this permit themselves. IRC P2722 sets kitchen-drain pitch and material rules (3/8-inch minimum slope, no flat bottoms, PVC or copper only in most cases). The most common plumbing rejection in Brighton is a drain stack that's too close to a window or exterior wall without adequate venting, or a sink trap that's oversized relative to the fixture (causing slow drainage and code violation). If you're relocating a kitchen sink more than a few feet, budget an extra $800–$2,500 for plumbing rough-in and inspection; if you're moving it to an island or peninsula, you'll need a sewage ejector pump (another $3,000–$8,000 plus electrical), and Brighton requires a separate mechanical sub-permit for the pump discharge line. Rough plumbing inspection happens before drywall closure; final inspection after fixture hook-up. Plan 2–3 weeks for plumbing sub-permit approval and inspection scheduling.

Electrical work in a full kitchen remodel includes two mandatory 20-amp small-appliance branch circuits (IRC E3702), GFCI protection on all countertop receptacles (IRC E3801), and potentially a dedicated 240V circuit for an electric range or double-oven. The two small-appliance circuits are non-negotiable and are the second-biggest rejection reason in Brighton after load-bearing walls—many DIY plans show only one circuit, and the inspector will require a re-submit. All counter receptacles must be spaced no more than 48 inches apart (measured along the countertop), and every outlet within 6 feet of a sink must be GFCI-protected (GFCI outlet or breaker). If you're adding an island or peninsula, every receptacle on that surface is treated as a countertop outlet and requires GFCI. Brighton requires a separate electrical sub-permit pulled by a Colorado-licensed electrician (no homeowner exception); expect $150–$400 in electrical permit fees. The electrical rough-in inspection happens before drywall, and the final inspection after all outlets and switches are live. Budget 2–3 weeks for electrical sub-permit review. Under-cabinet lighting, if hardwired, counts as a new circuit and must be on the electrical plan; plug-in task lighting is exempt.

Gas-line changes trigger a mechanical sub-permit in Brighton if you're moving a range, cooktop, or other gas appliance, or if you're adding a gas oven, griddle, or warmer. IRC G2406 requires all gas appliance connections to have a listed, flexible stainless-steel connector with an in-line regulator and shut-off valve; the old rigid copper or black-iron piping is still allowed but must meet slope and sediment-trap rules. Brighton's mechanical inspector will verify sediment-trap location (low point in the gas line with a drip leg), regulator pressure, and termination at the appliance. If you're moving a gas range more than 6 feet, you'll likely need to run new gas line from the existing stub, and this requires a trench permit if the new line runs under the foundation or exterior grade. Most kitchen gas-range relocations are within a few feet and can reuse the existing stub and connector, saving cost. Budget $300–$800 for a gas-line relocation sub-permit and inspection. If you're simply replacing an existing range with a new one in the same location, no permit is required—this is cosmetic replacement on an existing gas stub. Range-hood ducting that cuts through an exterior wall requires a detailed duct-termination drawing showing the exterior wall cap, slope (minimum 1/8-inch per foot), insulation (if applicable), and clearance from windows/doors; this is part of the mechanical or building sub-permit and is often overlooked until final inspection.

Brighton's permit timeline for a full kitchen remodel is typically 3–5 weeks for initial plan review (building, plumbing, electrical, and mechanical combined), plus 1–2 weeks for contractor corrections, then 2–4 weeks for actual construction and inspection scheduling. The city allows concurrent submittals (all three sub-permits filed at the same time), which speeds approval compared to serial review. Inspection sequence is rough plumbing, rough electrical, framing (if walls moved), drywall closure, then final inspections for all trades. Each subtrade inspection requires 1–3 business days notice to the city, and inspectors typically respond within 2–5 days; plan for 4–6 inspections total. Permit fees are calculated as a percentage of project valuation (typically 1.5–2% of hard costs), so a $35,000 kitchen remodel will incur $525–$700 in building permit fees, plus $150–$400 electrical, $150–$300 plumbing, and $100–$250 mechanical, for a total of roughly $925–$1,650 in permit costs. Brighton's online permit portal allows status checks, but plan review comments are typically emailed to the contractor or GC, not posted online. Owner-builder permits are allowed for owner-occupied 1–2-family homes; the homeowner pulls the building permit and arranges subs, but saves the 10–15% contractor license surcharge (not applicable here since licensed subs are mandatory for plumbing and electrical anyway).
