Buying a Fort Collins Rental? The Registration Ends at Closing, and the Certification Becomes Yours

"A registration shall terminate upon transfer of ownership of the registered long-term residential rental dwelling unit."

That sentence comes from the Fort Collins ordinance behind the city's rental registration program. It changes how buying a rental home here works. Since January 1, 2025, most long-term rentals in Fort Collins have needed a registration that is renewed every year. As part of it, the owner certifies that the property meets the city's minimum housing standards. The seller's registration can't be handed to you at closing. You file a new application, prove you are the owner or the owner's authorized agent, and sign a certification about a building you have owned for only a few days.

The city doesn't send an inspector before you sign. When an inspector does come out, though, the home almost never passes clean. So for a Fort Collins investor, the buyer's inspection period is effectively the only chance to check what you'll be certifying.

The Paperwork Is Light. The Promise Is Not.

On paper, the program looks like a minor administrative step. As of the city's current Rental Housing page, the annual fee is $37 per rental property plus $10 for each additional unit on the same parcel. A four-unit property, for example, comes to $67. Condos on their own parcels are registered one at a time. Owner-occupied homes and mobile home parks are exempt.

The certification is what carries weight. Under the ordinance, the applicant certifies that the property meets the "building, sanitation, mechanical, electrical, structural and fire safety requirements" in Chapter 5 of the City Code. Leasing a unit, or letting someone live in it, without a current valid registration is unlawful. We didn't find a post-closing grace period in the code we reviewed. In practice, your deadline is the day a tenant would move in under your ownership.

Fort Collins chose this lighter setup on purpose. An earlier 2023 ordinance called for inspections at initial registration and every five years after that. The version passed on June 20, 2023 replaced that schedule with inspections triggered by complaints. Today, renters can request an inspection if they believe a unit falls short. That means the first city inspector to see your rental will probably be there because your tenant called.

What Happens When an Inspector Actually Shows Up

At the August 18, 2026 City Council meeting, staff gave the most detailed update on the program so far. More than 9,000 properties had registered and self-certified, which staff estimated at about 80% of eligible rentals. The staff presentation also broke down inspection results.

• 134 inspections requested
• 58 not inspected
• 70 with issues that were then corrected
• 6 that met standards

Of the 76 rentals inspectors actually walked through, 70 had something that needed fixing. These were requested inspections, so the sample leans toward units where someone already suspected a problem. It doesn't show how the average Fort Collins rental would do. It does show how a typical complaint ends: the inspector usually finds something, and the owner has to correct it.

The same presentation counted the issues by category. Those counts are the most useful piece of the update for a buyer, because they show where inspectors tend to find problems.

Unpermitted work, with 83 issues, outranks plumbing and heating. Most of the items on this list are things a general home inspection might mention briefly. The difference is that you'll be signing a statement that they meet a specific municipal standard.

Turning the Table Into an Inspection-Period Checklist

The city's Landlord-Tenant Handbook spells out the standards behind those categories in measurable terms. Here are the ones that match the categories with the most issues. Each one is something you can measure or check during your inspection period.

1. Egress openings. Any required emergency escape opening must meet the code in effect when the home was built, or at least 720 square inches of net clear opening, whichever is greater. The sill can be no higher than 48 inches. This matters most in basement bedrooms.
2. Smoke and CO alarms. Smoke alarms go outside sleeping areas, inside each sleeping room, and on every story, basement included. CO detectors go within 15 feet of each sleeping room entrance on any level with lawful sleeping rooms, when the home has fuel-burning appliances or an attached garage.
3. Electrical. The minimum is 3-wire, 120/240-volt service rated at 60 amperes or more, with at least two separate receptacles placed apart in each habitable space. GFCI protection is required in bathrooms, laundry areas, and specified kitchen, garage, basement, and exterior locations.
4. Heat and hot water. Heating has to keep habitable rooms and bathrooms at 68°F or warmer, and water has to be heated to at least 110°F. A gas range can't count as a heat source.
5. Light and air. Each habitable room needs glazing equal to at least 8% of its floor area, plus an openable window of at least 4% of floor area. Bathrooms need an exterior window or an exhaust fan vented outdoors, and dryers need their own exterior exhaust.
6. Locks, screens, and exterior. Entry doors and low windows need secure locks, required ventilation openings need screens, and window wells near sidewalks or driveways need guards or covers.

A home can satisfy a lender, pass a standard inspection, and still miss one of these. Older homes with original electrical service and basement bedrooms with small windows are the obvious places to look.

The Basement Apartment Problem

The unpermitted work and illegal dwelling categories cover the risk that's hardest to fix after closing. A listing might describe a "basement apartment" or "income suite." The registration certifies compliance with the Land Use Code and with the building requirements. If the unit was never permitted, you are certifying something the paperwork doesn't support.

At the August 18 meeting, Chief Building Official Marcus Coldiron said the city generally tries to bring illegal units into "substantial compliance with the Building Code." He said that frequently means converting a single-family dwelling into a duplex. He also mentioned an earlier Council-approved program. It brought illegal units up to minimum life-safety codes and waived development review fees, and many units came into compliance through it. Mayor Francis asked whether the recent Land Use Code changes grandfather existing illegal units. Staff said they would follow up, and the proceedings don't include an answer.

There is a formal route. The city's ADU page says state law allows accessory dwelling units in every zone district starting February 2025, subject to city requirements. Attached basement ADUs can be up to 750 square feet or the full basement floor area. Existing accessory buildings can be converted up to 800 square feet. Every ADU goes through Basic Development Review, then a building permit and inspections. Building Services also notes that work exempt from permits is still not exempt from code. So the ADU route is an approval process with a review, a permit, and inspections. It isn't a stamp for a unit that's already finished. Permits submitted on or after April 1, 2026 fall under the city's current building code. That's the code a legalization project would likely be measured against.

If a property's rent projections depend on a second unit, it helps to know the permit history of that unit before the offer is final.

What's at Stake, and What's Changing

On paper, the penalties are steep. Coldiron told Council that citations can lead to fines of up to $3,000 per day, generally assessed by the Municipal Judge, though cases usually resolve before a fine is set. As of the August 2026 update, five citations had been written for registration issues, and all were dismissed or never reached court. The program works mainly through voluntary compliance, and the code allows enforcement when needed.

Fines aren't the main business risk. Staff explained that if the city suspends a registration or declines to renew it, the current lease stays in place. However, that lease can't be renewed, and the unit can't be leased to anyone else until the issues are fixed and the registration is renewed. For an investor, that can mean a vacancy you didn't plan for.

Some details will probably change. Staff listed several projects in progress: a review of the fee structure, FC Clear, a new registration system meant to be easier to use, better data collection, and more incentives for owners, managers, and tenants. Councilmember Hoeven asked that the review consider whether larger multi-unit buildings pay a fair share compared with duplexes and fourplexes. Staff said the program is designed to eventually be cost-neutral. The program has also put more than $200,000 into rental repairs and upgrades through incentives and grants. Those funds are usually earmarked in advance for things like safety or energy efficiency. Anyone planning a purchase for 2027 should expect the $37/$10 fees and the current portal to change.

Quick Answers

Does the seller's registration carry over if I keep the current tenant? No. Under the ordinance, registrations can't be transferred and they end when ownership changes, so the new owner applies on their own. How an existing lease is handled at closing is a question for your contract and your attorney.

Will the city inspect before I register? Under the current framework, no. Registration runs on self-certification, and inspections happen when someone requests one.

Do I register if I live in the house and rent a room? The city exempts owner-occupied units. If your situation is unusual, the Rental Housing team can confirm how the exemption applies.

If a Fort Collins rental you're considering has a basement unit or original electrical, Seth Hanson brings a construction and property management background to the inspection period, which helps sort out whether a fix is minor or whether it changes the deal. Let's Connect.
