Colorado is on the 2026 electrical code, and it already applies to your remodel
The change that will touch the most Denver-metro homeowners this fall has nothing to do with stadiums or land deals. On August 1, 2026, the State of Colorado adopted the 2026 National Electrical Code. Denver Community Planning and Development spelled out what that means for permit applicants in its notice on the adoption: every new project submitted for plan review on or after August 1 has to be designed to the 2026 NEC. Projects that were already in for plan review before that date are permitted to use the 2023 NEC as the basis of design.
Electrical licensing and the code inspectors enforce are set at the state level through the Colorado State Electrical Board, not city by city. So this is not a Denver-only rule — Arapahoe County, Aurora, Lakewood, Littleton, Centennial and the rest of the metro are working from the same edition. If you are collecting bids right now on a kitchen, a basement or an addition, the honest question to ask each contractor is short: which code edition did you price this to? A panel, a service upgrade and a circuit count drawn to the 2023 edition and submitted in October will come back with comments.
One more note: if your project has been sitting on a shelf since spring, the electrical scope is the part most likely to need a second look before it goes back to the city.
Energize Denver rules were revised — and here is who it actually covers
On August 27, 2026, Denver's Office of Climate Action, Sustainability and Resiliency adopted updated rules for the Energize Denver Building Performance Policy, following a multi-year outreach effort with building owners, property managers and contractors. The city groups the changes into four buckets: clearer timing around compliance deadlines, more flexibility for buildings with unusual circumstances, additional alternate compliance paths including adjusted targets and phased improvement plans, and more transparency about enforcement. Denver also stood up an Energize Denver Navigation Center to put the tools in one place.
We are including this because homeowners keep asking whether it applies to them. For a single-family house or a townhome, it does not. Energize Denver is a performance standard for larger commercial, multifamily and industrial buildings. If you own or manage an apartment building or a mixed-use property in Denver, it is worth reading the updated rules directly rather than relying on what circulated a couple of years ago — the compliance paths are genuinely different now.
Burnham Yard: the biggest thing on the metro's construction horizon
The Broncos' proposed stadium and mixed-use district at Burnham Yard keeps moving through the city's Large Development Review — the process Denver uses to give major redevelopment sites direction on infrastructure, multi-modal connections and open space before anything gets built. A community information meeting was held at La Alma Recreation Center in February, and the review runs alongside the broader Burnham Yard community planning effort.
Engineering News-Record has reported the project as a roughly $4 billion plan targeting a 2031 opening, with design work beginning and construction potentially starting as early as 2027. The 58-acre former railyard sits just east of I-25 between roughly 6th and 13th avenues, and the broader redevelopment is described in city materials as around 150 acres. Denverite has published the current renderings and district layout.
None of this is a 2026 problem for a homeowner. But if you live in La Alma-Lincoln Park, Baker, Valverde, Sun Valley or Athmar Park, this is the stretch where land values, rental demand and eventually construction traffic start moving. Homeowners in those neighborhoods who have been putting off a whole-home renovation are the ones we would tell to start pricing now, while residential trade availability is still normal.
Where the money went this week
BusinessDen's Pipeline column for September 4 is a decent read on where capital is actually landing in the metro. Three deals stood out:
- The Fitzgerald, 1840 Market St. — a 282-unit apartment and retail building completed in 2022, sold by Greystar to San Francisco-based Carmel Partners for $110 million.
- Berkeley Village Mobile Home Park, 5400 Sheridan Blvd. in unincorporated Adams County — sold to Invesco for $98.25 million.
- Peakline at Copperleaf Apartments, 4343 S. Picadilly St. in Aurora — a $72.5 million sale.
The pattern is worth noticing: large capital is buying existing housing rather than breaking ground on new. That tracks with what the trades are seeing — multifamily and office starts have cooled while data centers, power, public schools and transportation work pick up the slack. ENR's outlook noted that Denver project starts were expected to rise in 2026 on the back of that public and industrial work, not on the back of apartments.
Road work: US 287 in Broomfield, and the I-25 mobility hubs
CDOT announced on September 1 that it is beginning safety and traffic-flow improvements at four intersections along US 287 in Broomfield County, adding travel lanes and making signal and pedestrian upgrades. If you are in Broomfield, Louisville or north Westminster, that is your commute and your material deliveries.
South of town, the I-25 and CO 7 mobility hub work continues toward a fall 2026 finish, and the Lone Tree mobility hub along I-25 has run through the summer with overnight lane and ramp closures for barrier setting and re-striping. As always, COTrip is the source of truth for what is actually closed tonight — not a blog post written on Monday.
On the bid boards
If you are a sub or a supplier rather than a homeowner, Denver keeps two lists worth watching: Future Construction Solicitations for projects the city expects to advertise, and Current Bidding Opportunities for what is open now. CDOT posts its own current and future bidding opportunities. Both move weekly, so bookmark rather than screenshot.
What this means for your project
Four takeaways for a Denver-metro homeowner planning work this fall:
- Ask your contractor which electrical code they priced. Anything submitted for plan review on or after August 1 has to meet the 2026 NEC. This hits basements, kitchens, additions and any job that touches the panel or the service. If a bid from June is still sitting on your counter, it may be priced to the old edition.
- If your plans are already in review, confirm the older edition still applies. Projects submitted before August 1 are permitted to use the 2023 NEC as the basis of design. That is a real allowance — but confirm it with your reviewer rather than discovering it at inspection.
- Energize Denver is not a single-family rule. Do not let a sales pitch tell you otherwise. It applies to larger commercial, multifamily and industrial buildings. If you own one, the August 27 rules changed your options for the better.
- Residential trades are more available than they will be in a few years. With capital chasing existing apartment buildings instead of new starts, and the big public and stadium work still ahead, this is a comparatively calm window on the residential side. If a finished basement or a home addition is on your list, pricing it now is easier than pricing it later.
