Fort Collins legalised ADUs and cut parking minimums — with no mention of covenants anywhere

Fort Collins removed its own barrier to accessory dwelling units and left the private one entirely untouched and unmentioned. Ordinance No. 009, 2025 — “Amending the Land Use Code to Align with Two Adopted State House Bills Concerning Accessory Dwelling Units and Parking for Multi-Use Dwellings and to Clarify and Correct Certain Provisions” — passed on second reading for final adoption on February 4, 2025, after a unanimous Planning and Zoning Commission recommendation on November 21, 2024 and first reading on January 21, 2025.1

The full eighteen-page ordinance was extracted and searched. It contains zero occurrences of “homeowner,” “HOA,” “covenant,” “association,” “deed” or “restrictive.”

Its recitals state the driver plainly: HB24-1152 “require[s] the City to eliminate certain restrictions on ADUs and allow ADUs to be built in all zones where a single-unit dwelling exists or could be built by June 30, 2025.”

Where ADUs now go, and how big

UE (Urban Estate): detached house on a 21,780 square foot minimum lot, 100-foot minimum width, three storeys maximum — “Only one detached house on a lot, may include one (1) ADU.” ADU height: “No taller than Detached house on the same lot.”

RF (Residential Foothills): 100,000 square foot minimum lot, 200-foot minimum width, same one-ADU allowance — plus the constraint that no building on an RF lot “shall extend above five thousand two hundred fifty (5,250) feet above mean sea level.”

RL (Low Density Residential): detached house lot area is “the greater of 6,000 ft² or three (3) times the total floor area of all buildings excluding an ADU” — so ADU floor area is carved out of the lot-area calculation.

MH (Manufactured Housing): “Lot may include one (1) ADU”; the ADU must be “No taller than” and “No greater than the Mobile Home on the same lot.” Setbacks: front fifteen feet, rear ten, side ten, with ten feet minimum between the mobile home and the ADU and three feet between accessory structures.

OT (Old Town) A, B and C: one ADU maximum per lot; in OT-B and OT-C the ADU may sit on a lot with a detached house, duplex or triplex.

The parking change, and why it reaches boards

The second half of the ordinance implements HB24-1304. Recital F records the mandate: the bill “prohibit[s] the City from imposing minimum parking requirements on land use approvals for new multi-unit and residential mixed-use development after June 30, 2025.”

Retained residential minimums include: detached house — one space on lots with more than forty feet of street frontage, two spaces on lots with forty feet or less; duplex or rowhouse — one space per unit with two or fewer bedrooms, two spaces per unit with three or more; manufactured homes — one space per unit; fraternity or sorority — two spaces per three beds.

Short-term rental parking survives, on a scale: one to two bedrooms rented requires one off-street space; three to four require two; five to six require three; seven to eight require four. With one grandfather: STRs licensed under City Code § 15-646 “for which the license application was submitted prior to October 31, 2017, are exempt from compliance with these parking requirements so long as such license remains continuously valid.”

Why this matters to an association: Fort Collins has removed its own minimums for new multi-unit development. That does nothing to what a declaration may require on private drives and lots — but it does mean the city is no longer generating the off-street supply that some association parking and exterior rules historically assumed would exist.

There is also a Colorado statute that does reach parking directly and is older than any of this: HB22-1139 added C.R.S. 38-33.3-106.5(1)(d.5), which bars associations from regulating use of public rights-of-way running through their communities — parking, vehicle storage or other activities — regardless of what the governing documents say. An association enforcing a street-parking rule on a public street inside its boundaries is already outside its authority.

The definitions, and the occupancy footnote

The ordinance adds a definition of “Occupant” and revises the definitions of “Dwelling, single-unit,” “Dwelling, single-unit detached” and “Dwelling, two-unit” so that an attached ADU does not change the unit count.

It does not deal with occupancy limits, because Fort Collins had already handled those: a recital notes that Ordinance No. 081, 2024, effective July 12, 2024, removed familial-relationship occupancy limits from the Land Use Code, implementing HB24-1007.

And here is the point that gets missed statewide. HB24-1007 binds local governments. A common interest community is not a local government. Occupancy restrictions in a declaration are not touched by it. A Fort Collins board that quietly stopped enforcing an occupancy provision because “the state changed the law” changed its practice for the wrong reason.

What the silence means for a Fort Collins owner

An owner in a covenanted Fort Collins subdivision now has a city code that plainly permits an ADU and says nothing whatever about the declaration. The document that reaches the declaration is the state statute, not this ordinance: C.R.S. 38-33.3-106.5(4), added by HB24-1152, voids association provisions restricting an ADU as an accessory use to a single-unit detached dwelling in a designated jurisdiction, subject to a “reasonable restriction” exception.

So the sequence of questions is: is this a subject jurisdiction; is the home a single-unit detached dwelling; and is our restriction a reasonable one rather than a prohibition. None of those questions is answered by Ordinance No. 009, 2025.

What to do before the next application

Write the ADU rule in the reasonable-restriction lane. Placement, materials, height within the city's limits, prior notice. Not a ban.

Check the association's parking provisions against the public-right-of-way bar in C.R.S. 38-33.3-106.5(1)(d.5), and against the practical reality that new multi-unit development nearby may bring less off-street parking than the rules were drafted to assume.

Do not read the city's occupancy change as reaching the declaration. It does not.

And keep the two documents distinct when you answer owners. The city code says what Fort Collins will permit. The declaration says what the community permits. Fort Collins has been silent on the second, and that silence is not permission.
