The Lawsuit Won't Answer That. Your Lease Will. - URL: https://www.brianmccririe.com/energize-denver-costs-office-tenants/ - Published: 2026-10-08T12:01:00.000Z - Updated: 2026-10-08T12:01:01.000Z - Description: Energize Denver retrofit costs usually reach tenants through one clause: capital required to comply with laws. The lawsuit won't fix it. Your lease can. - Author: Brian McCririe - Tags: Lease Economics, Denver Office Market ## Can a Denver landlord pass Energize Denver compliance costs through to office tenants? Often, yes, and the route is usually one clause: the operating expense exclusion for capital costs that carves back in "improvements required to comply with laws." Energize Denver requires covered buildings of 25,000 square feet and larger to cut energy use roughly 30% by 2032, so the retrofit bill is real, and a federal lawsuit over the ordinance does not change what your lease already allows. Negotiate the amortization, the savings test, and the exclusions now, while the rule is in doubt and landlords still need tenants. ## The lawsuit is not your lease On September 1, a federal magistrate judge recommended that the industry challenge to Energize Denver and Colorado's Regulation 28 move forward, finding the plaintiffs had plausibly alleged the rules reach into HVAC and water-heating equipment that federal law reserves to the U.S. Department of Energy (Propmodo, citing the Denver Business Journal, September 1, 2026). The Justice Department had already told the court in June that it might participate if the case survived dismissal (Colorado Politics, July 2, 2026), and on September 15 the Justice Department filed a statement of interest arguing that federal energy law preempts the city and state rules (Denver Gazette, September 28, 2026). Judge Regina Rodriguez has not yet ruled on the magistrate's recommendation. That is a real legal fight, and the appellate courts have already split on the underlying question. The Ninth Circuit struck down Berkeley's gas ban; the Second Circuit upheld New York's building rules (Colorado Politics, July 2, 2026). Nobody can tell you how Denver's version ends, or when. Here's what the headlines skip. **Your landlord's obligations under Energize Denver and your obligations under your lease are two different documents.** The lawsuit only touches the first. If your lease lets the landlord recover capital spent to comply with laws, a landlord who replaces a chiller in 2027 to hit a 2028 target can bill you for it, and the bill does not go away because a judge later narrows the ordinance. The uncertainty cuts your way at the negotiating table, not in the courtroom. ## What Energize Denver actually asks of your building The mechanics matter, because they tell you what kind of spending is coming. - **Who is covered.** Commercial and multifamily buildings of 25,000 square feet and larger in the City and County of Denver report energy use annually and must hit Energy Use Intensity targets set by building type (Otten Johnson, September 8, 2025). Smaller buildings, from 5,000 square feet, carry lighter requirements. - **When.** The April 2025 rules update moved the first measured target to 2028, eliminated the 2027 interim target, and pushed the final target from 2030 to 2032 for buildings that opted in. Penalties for missing targets will not be levied until late 2029, absent other adjustments (Otten Johnson, September 8, 2025). - **How much.** Covered buildings must become roughly 30% more energy efficient by 2032 (Propmodo, September 1, 2026), and no building is required to cut EUI by more than 42% (Otten Johnson). - **Where buildings stand.** 35% of covered buildings were in compliance as of late 2025, up from 15% in 2022 (Propmodo, citing the city). Read that last line the other way. **Roughly two-thirds of covered buildings still had work to do** as of the last count. That work is HVAC replacement, controls, lighting, envelope, and in some cases electrification. It is capital, and capital is exactly what a well-drafted landlord lease tries to move into operating expenses. One geographic note for suburban tenants: Energize Denver is a City and County of Denver ordinance. Much of the Denver Tech Center sits in Greenwood Village and Centennial, outside it. Colorado's statewide building performance rule under Regulation 28 applies separately to larger buildings, 50,000 square feet and up, across the state. Check which rule governs your building before you negotiate against the wrong one. ## How compliance costs reach your operating expenses Most Denver office leases, gross or net, start from the same place: capital expenditures are excluded from operating expenses. Then come the exceptions, and there are usually three. 1. **Capital improvements required by laws enacted after the lease date.** This is the Energize Denver door. The fight is over the word "enacted." Energize Denver's performance requirements date to 2021, and the rules have been rewritten since. A landlord will argue that each new target and rules update is a new requirement. You want the clause to say the opposite. 2. **Capital improvements that reduce operating expenses.** Efficiency retrofits fit this description by design. The landlord's pitch is simple: the upgrade lowers utility costs, so tenants who benefit should share the cost. 3. **Capital repairs and replacements amortized over useful life.** A chiller at end of life is a replacement whether or not an ordinance requires it. None of those exceptions is unreasonable on its face. The damage is in the details: the amortization period, the interest rate, whether recovery ends when your lease does, and whether the savings the landlord promised ever have to show up. That is where a clause written in the landlord's favor turns a seven-figure retrofit into a line item you pay for the rest of your term. If you're on a [full service gross lease rather than NNN](https://www.brianmccririe.com/full-service-gross-vs-nnn-denver-office/), don't assume you're insulated. In a base-year structure, an amortized capital charge that shows up after your base year flows straight into your share of the increase. ## Six clauses to negotiate before you sign or renew This is the checklist I'd run on any Denver office lease in a covered building right now. 1. **Amortize over useful life, at a stated rate, inside your term.** Require that any includable capital cost be amortized on a straight-line basis over its useful life under generally accepted accounting principles, with the interest rate named, and that you pay only the installments that fall within your term. A 20-year HVAC system should cost you 5/20ths on a five-year lease, not most of it. 2. **Tie recovery to real savings.** Denver's own green-lease guidance, published by the city's Office of Climate Action, Sustainability and Resiliency, offers sample language limiting an annual pass-through to the prorated capital cost over the improvement's life cycle and addressing costs that exceed the operating savings actually achieved. Ask for that version. If the landlord's retrofit is supposed to cut utility costs, the tenant's share of the capital cost should not exceed the savings it produces. 3. **Pin down "enacted after."** Define compliance-with-laws capital as costs required by laws first enacted after the lease date, and state that Energize Denver and Regulation 28, including amendments to their targets and timelines, are existing laws for purposes of the clause. That one sentence moves the compliance obligation back where it belongs: on the owner, who bought or financed the building knowing the rule existed. 4. **Exclude penalties, fees, and the owner's compliance administration.** Fines for missing a target, benchmarking verification, consultant fees, and costs of a landlord's timeline-extension or hardship application are ownership costs. Say so in the exclusions list. 5. **Get the building's compliance position in writing.** Ask the landlord to represent whether the building has met its benchmarking obligations, which target path it is on, and what capital work it expects through your term. Denver publishes building-level benchmarking results; compare what the landlord tells you with what the city reports. 6. **Keep your audit right, and use it.** A pass-through you can't examine is a pass-through you can't challenge. Energy capital belongs inside your [operating expense audit rights](https://www.brianmccririe.com/denver-office-lease-audit-operating-expenses/), and the annual cap you negotiated on controllable expenses should say plainly whether amortized capital sits inside it or outside it. The [non-cumulative cap on controllable expenses](https://www.brianmccririe.com/operating-expense-caps-denver-office-lease/) is worth less if energy capital walks around it. Your leverage to get these depends on the building and the submarket. With downtown office vacancy at 38.6% as of Q2 2026, per CBRE, most landlords would rather concede an amortization schedule than lose a renewal. In a tight building, you'll trade harder for the same language. ## The distressed-building wrinkle Energize Denver's 2025 rules let an owner apply for a 24-month pause on demonstrating compliance for qualifying financial distress, which includes a building controlled by a court-appointed receiver, a tax lien sale, or a deed in lieu of foreclosure. Financial solvency concerns, including loan maturities and the cost of renewing or replacing tenants, can also qualify (Otten Johnson, September 8, 2025). That matters now. Republic Plaza, downtown's tallest tower, went into receivership in September (9News, September 16, 2026). A pause defers the retrofit. It does not cancel it. A new owner who buys a distressed building at a reset basis inherits the compliance clock, and the capital program lands in the back half of your lease rather than the front. If your building is in special servicing or receivership, read the pass-through language with that timeline in mind, alongside the broader [landlord default risk questions](https://www.brianmccririe.com/landlord-default-risk-denver-office-renewal/) you should already be asking. Pass-through protections are worth more, not less, when the next owner is unknown. Energize Denver, Regulation 28, and lease pass-through language are legal questions as much as business ones. Have your own counsel read the actual clause and the current rules before you rely on any of this. ## Frequently asked questions **Does the federal lawsuit stop Energize Denver right now?** No. As of early October 2026, a magistrate judge has recommended the challenge proceed and the Justice Department has filed a statement of interest supporting the preemption argument, but the ordinance and its reporting obligations remain in effect until a court says otherwise. Penalties for missing performance targets are not scheduled to begin until late 2029 under the 2025 rules. **Can my landlord charge me for a new HVAC system required by Energize Denver?** It depends on your lease's capital expense exclusions. Most leases exclude capital costs but carve back in improvements required by law or that reduce operating costs. If yours does, the landlord can usually recover an amortized share, which is why the amortization period, interest rate, and savings test matter more than the headline. **Does Energize Denver apply to buildings in the Denver Tech Center?** Only to buildings inside the City and County of Denver. Much of the DTC sits in Greenwood Village and Centennial, where Energize Denver does not apply, though Colorado's Regulation 28 covers buildings of 50,000 square feet and larger statewide. Confirm your building's jurisdiction before you negotiate. **What should a tenant ask for in a green lease clause in Denver?** Straight-line amortization over useful life at a stated interest rate, recovery limited to your lease term, a cap tied to demonstrated energy savings, exclusion of penalties and compliance administration, and a landlord representation on the building's compliance status. The city's own sample lease clauses are a reasonable starting point. **Does a full service gross lease protect me from Energize Denver pass-throughs?** Not entirely. In a base-year gross lease, amortized capital that enters operating expenses after your base year raises your share of the increase. Read the capital exclusions in a gross lease as carefully as you would in an NNN lease. ## The rule may change. Your clause won't unless you change it. The Energize Denver lawsuit will take its time. Your renewal or new lease will not wait for it, and the clause you sign now governs every dollar of retrofit capital your landlord spends through your term, whatever a judge decides. Fix the amortization, tie it to savings, and define the ordinance as an existing law while landlords still need the deal. --- **If you're working through a lease decision in Denver, whether that's a renewal, a relocation, or a footprint question your CFO is pushing on, I'm happy to run the numbers with you.** [**Schedule a conversation.**](https://www.brianmccririe.com/meet-with-brian-mccririe/) --- **About Brian McCririe** Brian McCririe is Executive Managing Director of SVN | Denver Commercial and National Council Chair for Occupier Services across the SVN network.
