What does Lafayette's all-electric building code mean for new-home buyers?
According to Colorado real estate broker Nick Ahrens, Lafayette's 2026 building code bans natural gas in new construction starting August 1, 2026, so any home permitted after that date will be all-electric: heat-pump heating and cooling, a heat-pump water heater, and an electric or induction range in place of gas appliances. The rule does not touch existing homes or homes already permitted before the cutoff, and it does not force you to give up gas if you buy resale. For new builds, the questions that actually matter are what the all-electric systems cost to run, whether the electrical panel is sized for them, and — above all — which version of the code your specific permit falls under.

Nick Ahrens, a Colorado real estate broker with The Apollo Group at eXp Realty who walks relocating buyers through new-construction contracts every month, tells clients that in Lafayette the permit date now decides whether a new home has a gas line at all. That is a bigger deal than it sounds. If you are shopping new construction in Lafayette this summer or planning a build, the code changing under your feet is not a detail to sort out at closing — it shapes the appliances, the utility bills, and the questions you should be asking the builder before you sign.
Here is what changed, and the step-by-step of how to buy under it.
What Lafayette actually adopted
Lafayette is adopting the 2024 family of International Codes plus the 2026 National Electrical Code, with a tentative effective date of August 1, 2026. In place of the standard energy code, the city adopted the Metro Cohort Model Code, a regional standard built with Boulder County and eight neighboring communities and pegged to Colorado's new Low Energy and Carbon Code.
The headline piece for buyers is a local amendment: all new residential construction must be all-electric. In plain terms, Lafayette banned natural gas hookups in new homes. Commercial projects get some carve-outs — commercial kitchens, hospitals, labs, and large industrial systems — but new houses and townhomes do not.
Two more requirements ride along with it, and both were already part of Lafayette's code before this update:
Solar-ready. New homes under 5,000 square feet must run conduit from the roof to the electrical panel and reserve roughly 300 square feet of roof area for a future solar array. You are not required to install panels — the house just has to be wired to accept them.
EV-ready. New construction has to include electric-vehicle charging infrastructure, so your garage is built to take a Level 2 charger without a panel upgrade later.
One point worth clearing up, because it confuses a lot of relocating buyers: Colorado's statewide Low Energy and Carbon Code, which became the state's minimum energy code on July 1, 2026, does not ban gas. It levels the playing field so efficient heat pumps compete with gas on equal footing. Lafayette chose to go further than the state and require all-electric outright. That is why a new home in Lafayette follows a different rule than a new home in a metro suburb that only adopted the state minimum.
What all-electric means inside the house
If you have never lived in an all-electric home, the swap list is short:
A heat pump for heating and cooling instead of a gas furnace plus a separate air conditioner.
A heat-pump water heater instead of a gas tank or tankless unit.
An induction or electric range instead of a gas cooktop.
An electric dryer and, usually, no gas fireplace.
Cold-climate heat pumps handle Front Range winters — this is not the technology from fifteen years ago — but they behave differently than a gas furnace, and that is the part buyers should understand before they fall in love with a floor plan.
Does all-electric cost more? The honest numbers
On the build side, it is roughly a wash. Cost studies in Colorado put an all-electric new home at about the same total as a comparable gas home: the heat pump runs close to a furnace-plus-AC setup, and while the heat-pump water heater and induction range cost a little more, you save the price of running a gas line and meter to the house.
On the operating side, also close. With current Xcel rates, a properly sized cold-climate heat pump costs about the same to run over a full Denver-area heating season as a high-efficiency gas furnace — usually within $50 to $100 either way. Heat pumps are cheaper to run in the shoulder seasons and above roughly 25 degrees; gas pulls ahead on the coldest stretches below about 10 degrees. Over a year on the Front Range, it evens out for most homes.
One thing not to bank on: the rebates. Xcel and Colorado offer real incentives on heat pumps and heat-pump water heaters, but on a brand-new home those typically flow to the builder or the original owner at the time of installation. As a later buyer, you inherit the equipment, not a fresh rebate check. Budget the home on its own merits.
When Nick Ahrens tours a Lafayette spec home with buyers, the first question he asks the builder is which code the permit falls under — because a home permitted July 30 can still be built with gas, while the identical plan permitted August 2 cannot.
How to buy a new-construction home in Lafayette under the 2026 code
Pin down the permit date. Ask the builder, in writing, when the building permit was issued or is expected. A permit issued before August 1, 2026 is generally grandfathered under the prior code and may include gas; a permit after the cutoff must be all-electric. This single fact decides your appliance list.
Get the systems list and the panel size in writing. Confirm the heating, water heating, cooking, and dryer specs, and confirm the electrical service (200-amp is standard for all-electric). You want no surprises about what is electric and whether the panel has room for an EV charger and future solar.
Decide whether all-electric fits how you live. If you cook on gas by preference or want gas as backup heat, an all-electric new build may not be your home — and that is a real reason to look at resale instead. Weighing a new build against an existing home is its own decision, and it is worth reading a straight new-construction-versus-resale breakdown before you commit. If gas is a must-have, the older-home path in nearby markets comes with its own inspection checklist.
Inspect the systems on your own timeline. New construction still gets inspected. Use your CREC Inspection Objection and Resolution deadlines — the dates that run from mutual execution of the contract — to schedule a pre-drywall walk and a final inspection, and have the heat pump and heat-pump water heater commissioned and documented. Builders often substitute their own contracts for the standard Colorado form, so read the inspection and warranty terms closely.
Line up insurance and your utility budget before you close. An all-electric home has no gas bill and a different electric profile; ask the builder or a neighbor for real usage numbers, and confirm your homeowners policy prices the home normally. Deadline-driven Colorado contracts do not wait, so start these before the objection window closes.
How this fits the rest of the Lafayette market
Lafayette home values sit around $675,000 to $720,000 in mid-2026, down roughly 4.6 percent over the past year, with homes taking about 51 days to sell. With 30-year mortgage rates near 6.49 percent, buyers have a little more room to negotiate than they did a year ago. New all-electric inventory will grow from August forward, while the existing gas-equipped housing stock becomes the only way to buy a Lafayette home with a gas line. That does not make either one better — it makes them different products, worth comparing deliberately. If you are also weighing Lafayette's older neighborhoods, the ground under Old Town carries its own due-diligence story worth knowing.
Lafayette is not alone in this, either. Deadline-driven local codes are reshaping what you can build and buy across the north metro — Wheat Ridge, for instance, set its own August compliance deadline for accessory units. The pattern is the same: the calendar, not just the price, now shapes the deal.
Frequently Asked Questions
Does Lafayette's new code mean I can't get a gas stove in a new home?
In new construction permitted on or after August 1, 2026, yes — the home will be all-electric, so you would cook on an induction or electric range rather than gas. If gas cooking is non-negotiable, your options are a home permitted before the cutoff or an existing resale home that already has gas service.
Can I still buy a home with natural gas in Lafayette?
Absolutely. The all-electric rule applies only to new construction going forward. Every existing home in Lafayette keeps its gas service, and resale homes with gas furnaces, water heaters, and ranges are unaffected by the code.
Will an all-electric home cost me more to run in Colorado?
Usually not by much. Over a full Front Range heating season, a properly sized cold-climate heat pump runs within about $50 to $100 of a high-efficiency gas furnace at current Xcel rates. You also drop the fixed monthly gas meter charge, since there is no gas service at all.
Does the requirement apply to remodels and additions?
The all-electric amendment targets new construction. Remodels, additions, and appliance replacements in existing homes follow different rules, and you can generally keep gas appliances in a home that already has them. Confirm your specific project scope with the Lafayette Building Division before you plan.
What if the builder's permit was issued before August 1, 2026?
A home permitted before the effective date is generally built under the prior code, which allowed gas. That is why the permit date is the first thing to confirm on any Lafayette new build this year — two identical floor plans can have completely different mechanical systems depending on which side of the deadline the permit landed.
Before you sign on a new Lafayette build
Lafayette's all-electric code does not make new construction better or worse — it makes it a specific product, and the permit date is what tells you which product you are buying. Get that date in writing, confirm the systems and the panel, and decide whether all-electric matches how you actually live before you go under contract.
