C-470 and Bowles Avenue interchange work starts this week
CDOT and contractor Jalisco International began work at the C-470 and Bowles Avenue interchange on August 10. It is a signals-and-sidewalks job rather than a widening: crews are replacing traffic signal equipment — poles and cabinets — at both ramp intersections, adding a metering signal to the westbound on-ramp, and rebuilding curb ramps, median islands and sidewalk layouts to meet ADA standards and improve bike navigation. Drainage work is part of the scope too.
Working hours are 8:30 a.m. to 3:30 p.m., Monday through Friday, with single-lane and shoulder closures inside the work zone during those hours. Cyclists on the C-470 Bikeway get detoured around the Bowles intersection using Alkire Street and Coal Mine Avenue. CDOT expects to finish in early 2027; the project page is where updates get posted.
The practical effect is narrow but real. If your house is in Ken Caryl, Columbine, or west Littleton, the daytime window is exactly when a lumber truck, a concrete pour, or a roll-off swap wants to come through. Deliveries scheduled before 8:30 or after 3:30 will move a lot more predictably for the next six months. We flag this on job schedules for Ken Caryl and Littleton projects the same way we flag a street with no alley access.
Denver's 90-day permit track — and what it does not cover
Denver's Community Planning and Development office rolled out a 90-calendar-day review path for affordable housing in late June, run through an Affordable Housing Review Team. The city says it piloted the process starting in fall 2025 before making it standard.
For most homeowners this is background noise, with one exception worth knowing: deed-restricted accessory dwelling units are on the eligibility list. A project qualifies if it meets at least one of the criteria the city published, and deed-restricted ADUs are one of them. If you were already weighing an ADU in Denver and were open to a deed restriction on the rent, that is a genuinely different timeline than the standard residential queue.
If you are not deed-restricting anything — a normal basement, addition, or kitchen — you are still in the regular line, and the regular line is the thing to plan around. Our Denver-metro permit guide tracks what each jurisdiction actually asks for, because Arapahoe County, Greenwood Village, Lakewood and Denver proper are not the same process even when the work is identical.
135 units on Federal Boulevard reach their financing step
A 135-unit income-restricted project at 4745 Federal Boulevard, a Denver Housing Authority partnership with the Colorado Coalition for the Homeless, was approved by the city in March and is applying for 4% housing tax credits through the Colorado Housing and Finance Authority this month. Construction is targeted for late 2027, pending financing.
The reason a remodeling company mentions this: the Berkeley and Sunnyside side of Federal is going to be a construction corridor for years, and the timeline shows how the funding math actually works. City approval in March, tax credit application in August, shovels in late 2027. Big projects move slowly and in public. Yours does not have to, but it is a useful reminder that "approved" and "under construction" are very different words.
Where costs are actually moving right now
ENR describes the Denver market as steady through 2026, with health care expansion strong and multifamily moving at a more measured pace than the last few years. Steady does not mean cheap. The pressure has shifted away from framing lumber and toward metals and finish materials.
Per the Associated Builders and Contractors Rocky Mountain chapter's cost analysis, steel, aluminum and copper items carry substantially higher tariff rates than softwood lumber does, with derivative products taxed separately. HousingWire's reporting on builder material costs points at the same pattern: metal trim, cabinets, appliances and fixtures — the things that finish a room — are carrying the price increases, not the studs behind the drywall.
That maps cleanly onto what we see in bids. Rough framing on an addition prices about where it did last year. The range hood, the appliance package, the plumbing fixtures, the metal roof edge, and the window packages are where a budget drifts. If you want to see how the split works on a real scope, the numbers on our Denver remodeling pricing page are broken out by category for that reason.
- Order finishes early. Appliances and plumbing fixtures are the long-lead, price-volatile items. Pick them during design, not during framing.
- Lock allowances with real products. A "$6,000 appliance allowance" is not a price. A model number with a quoted price is.
- Ask what a quote's validity window is. Thirty days is common on metal-heavy line items right now, and that is worth knowing before you sit on a proposal for six weeks.
The 2025 Denver codes are the codes now
Worth repeating because it still catches people: Denver adopted the 2025 Denver Building and Fire Codes in June 2025, effective at the end of December 2025, based on the 2024 International Codes with the 2021 IECC for energy. The transition period is over. Any plan set drawn against the older Denver amendments is going to get comments.
Where this bites homeowners is in old drawings. If an architect drew your basement or addition in 2024 and the project sat, do not assume the set is still permit-ready. Egress sizing, energy compliance paths, and fire separation details are the usual corrections. It is cheaper to have the drawings updated before submittal than to eat two review cycles finding out.
What this means for your project
- Southwest metro homeowners: shift deliveries outside 8:30–3:30. The C-470 and Bowles work runs into early 2027 on weekdays. Concrete, lumber, and dumpster swaps are the ones that hurt when a lane closes.
- Deed-restricted ADU? Ask about the 90-day track. It is a real, published path with published criteria. It is not for standard remodels, but if it fits your plan, it changes your calendar meaningfully.
- Budget the finishes, not the framing. The cost pressure this year sits in metals, cabinets, appliances and fixtures. Selections made early protect a budget better than any amount of negotiating on labor.
- Refresh old plan sets. Drawings that predate the 2025 code adoption should be reviewed before they go to the city.
- Run your own numbers first. Before you call anyone, our basement finishing calculator and the scope breakdowns on home additions will tell you whether a project is in your range at all.
Nothing this week changes what a good remodel costs or how long it takes. It changes when your trucks can get down Bowles, which drawings your plan reviewer will accept, and which line items on your bid deserve a second look before you sign.

Most of this week's news is about waiting — waiting on a lane to open, waiting on a plan reviewer, waiting on a cabinet order. You don't beat that with hustle. You beat it by ordering early and building the wait into the schedule instead of pretending it isn't there.DT · Owner, BH Builders
