Inclusionary Housing and Mitigation Requirements in Broomfield, Colorado

What triggers the requirement, and what it actually requires

Broomfield's Inclusionary Housing Ordinance (IHO), Chapter 17-76 of the Municipal Code, was adopted in 2020 and applies to residential developments containing 25 or more for-sale units, or more than 5 units marketed primarily as rental housing. For a qualifying rental project, the ordinance requires 20% of the units to be income-restricted at 60% of Area Median Income (AMI) -- alternatively, a developer can pay a cash-in-lieu fee under a schedule the Housing Division maintains, or propose an alternative compliance approach that requires City Council approval. For-sale projects face an analogous set of income-aligned unit or cash-in-lieu obligations under the same chapter.

The Planning Department and the Housing Division both get involved before a qualifying project even reaches formal application: the pre-application process requires the developer to lay out specifically how the project will meet the IHO's requirements, meaning this isn't a condition negotiated late in the process -- it needs to be underwritten into a project's cost and unit mix from the start.

Income-restricted units carry a long affordability tail

Units built to satisfy the IHO are income-verified at purchase or lease-up and deed-restricted, with annual market-rate appreciation capped to keep them affordable for at least 30 years from initial occupancy. That's a genuinely long compliance horizon for a for-sale project specifically -- a buyer of one of these income-restricted units, or a developer planning to build them, needs to understand the resale-price formula and monitoring requirements that stay attached to the unit for three decades, not just at the initial sale.

For a developer evaluating a Broomfield parcel, that long tail is also a design and marketing constraint: income-restricted units typically need to be distributed and finished comparably to market-rate units in the same project under most inclusionary programs, so factor that into per-unit cost assumptions rather than treating the IHO units as a separate, lower-cost product line.

What to confirm before underwriting a project

• Whether the specific project's unit count and rental/for-sale mix crosses the IHO's 25-unit (for-sale) or 5-unit (rental) threshold -- a project sized just under either line avoids the requirement entirely.
• The current cash-in-lieu fee schedule from the Housing Division if paying the fee is more attractive than building income-restricted units on-site.
• Whether the site sits on a legacy-zoned parcel (see the hub's legacy-zoning coverage) where the underlying zone code, not just the IHO, could affect unit count or density assumptions.
• Current program status and any amendments to Chapter 17-76 directly with the Housing Division, since inclusionary housing policy has been an active area of both local and statewide legislative attention.
