Section 179D

Energy-Efficient Commercial Buildings Deduction

Per-square-foot deduction for qualifying HVAC, hot water, lighting, and envelope improvements. 2026 rates with prevailing wage and apprenticeship reach $5.81/sqft. The base rate without those labor standards is around $1.16/sqft. Building owner claims the deduction, or for public buildings the designer can receive an allocation.

Section 179

First-year expensing

Since the 2018 TCJA update, HVAC installed in nonresidential real property qualifies for Section 179 expensing. For 2026 the deduction limit is indexed to roughly $1.22M with a phase-out starting around $3.05M in total equipment placed in service. That means most small and mid-size commercial owners can expense the entire qualifying HVAC cost in year one instead of depreciating over 39 years.

Residential rental property (27.5-year MACRS) generally does not qualify for Section 179 on HVAC. Verify with your CPA.

What commercial HVAC incentives are available in NYC?

Commercial NYC HVAC projects can stack Con Edison Clean Heat Commercial ($120/MMBtu full building or $70/MMBtu phased), Section 179 first-year expensing (~$1.22M limit in 2026), bonus depreciation (20% in 2026, 0% in 2027 under current law), Section 179D deduction (up to $5.81/sqft with prevailing wage and apprenticeship), Section 48 Investment Tax Credit for commercial geothermal (30% base plus bonus adders), and NYC C-PACE financing (100% of project, up to 30 years).

What is Section 179D?

Section 179D is a federal tax deduction for energy-efficient commercial buildings. For 2026 the maximum rate is $5.81 per square foot when prevailing wage and apprenticeship rules are met. Base rate is around $1.16/sqft without those labor standards. Qualifying systems: HVAC, hot water, interior lighting, and building envelope. The building must beat an ASHRAE 90.1 reference case by program thresholds, and a third-party certifier provides the modeling and site visit. Building owners claim the deduction, or (for public buildings) designers can be allocated it.

Is bonus depreciation going away?

Yes, under current law. 60% in 2024, 40% in 2025, 20% in 2026, 0% in 2027. Commercial owners placing HVAC in service before December 31, 2026 capture the final year of bonus depreciation on Qualified Improvement Property. If Congress extends the schedule that changes, but plan on current law.

How much can Local Law 97 cost my building?

LL97 applies to NYC buildings over 25,000 sqft. Emissions over your building's cap are penalized at approximately $268 per ton of CO2 equivalent annually. Caps tighten in 2030 and 2035. A 50,000 sqft office 100 tons over cap pays roughly $26,800 per year, every year it stays over. HVAC electrification is the single biggest compliance lever. Combined Clean Heat + 179D + bonus depreciation typically covers 40 to 60% of the retrofit capex.

Can I stack Section 179, 179D, and bonus depreciation?

Yes. A CPA typically orders them: Section 179 first (year-one expensing up to the annual limit), Section 179D next (per-square-foot deduction on the energy-efficient portion), bonus depreciation on the balance of Qualified Improvement Property at the current year rate. Each requires separate documentation. Section 179D in particular requires third-party certification.

What is C-PACE?

NYC C-PACE (Commercial Property Assessed Clean Energy) is long-term financing (up to 30 years) for commercial energy upgrades. It funds up to 100% of project cost at fixed rates, is repaid through a property tax assessment, and transfers with the property on sale. Existing mortgage lender consent is required. NYCEEC administers NYC C-PACE. Typical close runs 60 to 90 days.

How long does Clean Heat Commercial take?

Commercial custom-path projects run 3 to 6 months from engineering submission to incentive confirmation. Engineering documentation (MMBtu calc) goes in first, Con Edison reviews and issues Notice to Proceed, pre-inspection happens, install proceeds, post-inspection confirms the rebate. Vinco Mechanical manages the engineering and Con Edison coordination.

Does commercial geothermal qualify for federal incentives?

Yes. Section 48 Investment Tax Credit covers 30% of commercial geothermal heat pump cost, with bonus adders: +10% domestic content, +10% energy community, plus low-income project additions. Prevailing wage and apprenticeship are required for credit above the 6% base. Section 48 stacks with Section 179, 179D, and NYC C-PACE.
