We have answered a lot of questions about Chicago's Northwest Side Preservation Ordinance — also called 606 TOPA (Tenant Opportunity to Purchase Act). From sellers who've never heard of it to investors who thought they understood it and didn't, the same questions come up again and again.
This post is our attempt to answer all of them in one place. It's organized by who's asking — sellers, buyers, landlords/investors, and tenants — so you can jump to the section that's most relevant to you. Where questions have more detailed answers in other posts, we link there.

Why Selling on the Northwest Side Takes Longer Than You Think
The Basics
What the ordinance is, where it applies, and who it affects
What is the Northwest Side Preservation Ordinance?
It's a Chicago law passed in 2022 that gives tenants in certain Northwest Side neighborhoods the right to purchase the rental property they live in before it can be sold to an outside buyer. Sellers must formally notify tenants and the City of Chicago before listing, and must allow a waiting period during which tenants can submit financing documentation and exercise their right to buy. It's also called 606 TOPA — the Tenant Opportunity to Purchase Act — after the 606 Trail, the elevated park corridor that runs through the covered area.
Which neighborhoods are covered?
The ordinance covers properties in Logan Square, Avondale, Hermosa, Humboldt Park, and West Town. Properties outside these neighborhoods — even adjacent ones like Irving Park or Pilsen — are typically not covered, though the specific boundary matters more than the neighborhood name. If you're not sure whether your address is in the zone, ask your agent or check with the City of Chicago Department of Housing.
Does it apply to all properties in the covered area?
It applies to rental properties — buildings where at least one unit is occupied by a tenant at the time of sale. Owner-occupied single-family homes with no tenants are typically not subject to the ordinance's notice and response requirements. If any portion of the property is rented, even a coach house or garden unit, the ordinance likely applies.
Why does the ordinance exist?
Property values along the 606 Trail and in adjacent neighborhoods rose sharply after the trail opened in 2015, accelerating displacement of long-term residents who rented in those neighborhoods. The ordinance was designed to give tenants a structured opportunity to purchase the buildings they live in before those buildings are sold to investors or owner-occupants, giving renters a path to stay in their neighborhoods even as values rise.
Questions for Sellers
If you own a rental property in the covered area and are thinking about selling
What do I actually have to do as a seller?
At minimum: prepare and deliver a formal Notice of Intent to Sell to each tenant in writing with documented delivery confirmation; file that notice with the City of Chicago Department of Housing; post physical copies at every building entrance; wait for the required response window to close without a qualifying tenant offer; then proceed to the open market. The full step-by-step process is covered in our compliance checklist post.
How long do I have to wait before I can list?
The notice and response periods depend on the number of occupied units in your building: 15 days for 1–2 unit buildings, 30 days for 3–4 unit buildings, and 60 days notice plus a 90-day response window for buildings with 5 or more occupied units. These clocks start from confirmed delivery of the notice to tenants — not from when you sent it.
Can I market the property while the waiting period runs?
Yes. You can list on the MLS, hold showings, and collect buyer interest during the tenant response window. What you cannot do is execute a binding purchase contract with an outside buyer before the window closes. Many sellers use the notice period productively — getting qualified buyers interested before they're even allowed to go under contract.
What if my tenant verbally says they don't want to buy?
A verbal statement doesn't formally close the response window. To exercise or decline the right, tenants must act in writing. A signed written declination from a tenant ends their response window early and provides clean documentation for your closing file. Many tenants are happy to sign one once they confirm they're not interested — it's worth asking, and it can shorten your pre-listing phase.
What if I lower my asking price after sending the notice?
A significant reduction from the price stated in the original notice may require issuing a new notice at the updated price and restarting the response period. This is why pricing strategy under the ordinance is different from a standard listing — we work through this before the notice goes out, not after.
What are the penalties for non-compliance?
Fines run from $200 to $1,000 per day per offense. Beyond fines, non-compliance creates documentation gaps that title companies and buyer's attorneys will discover during due diligence — and that can delay or kill a closing even after the property is under contract.
Do I need to use a lawyer?
Illinois real estate closings involve attorneys by standard practice. Given the formal documentation requirements of the ordinance, having your attorney draft or review the Notice of Intent to Sell and confirm your compliance packet before going under contract is important — not optional.
I have a month-to-month tenant. Does the ordinance still apply?
Yes. Month-to-month tenants are still tenants under the ordinance. Their lease structure doesn't affect their notice rights.
What if my tenant is behind on rent?
Rent delinquency doesn't exempt a tenant from their rights under the ordinance, and it doesn't exempt you from the notice requirement. If you're managing a rent issue alongside a sale, discuss the full picture with your attorney before starting the compliance process — the two situations can affect each other in ways that need careful handling.
How does this affect my total selling timeline?
For most 3–4 unit properties, expect to add 6–8 weeks to the pre-listing phase. When handled correctly — starting the compliance process before the property goes on the market — it adds zero days to your active market time. From decision-to-sell to closing, plan for 10–14 weeks minimum. See our full timeline breakdown in this post.
Questions for Buyers
If you're purchasing a rental property in the covered area
How do I know if the seller has complied?
Ask for the compliance documentation before you make an offer — or at minimum, during attorney review. A compliant seller will have: a copy of the Notice of Intent to Sell, proof of delivery to each tenant, confirmation of DOH filing, proof of posting at building entrances, and documentation of the tenant response period (either signed declinations or dated confirmation that the window lapsed). If a seller can't produce this, treat it as a significant due diligence flag.
Can I go under contract while the tenant response window is still open?
Technically, a seller should not execute a binding contract with an outside buyer until the window closes. If you find yourself in a situation where the response period is still active, understand that the deal is genuinely contingent — a tenant could step forward with qualifying financing before the window closes. Discuss this risk clearly with your agent and attorney.
What happens to my deal if a tenant exercises their right to purchase?
The tenant steps in front of you as buyer. The seller must negotiate with the qualifying tenant first. If the tenant's purchase proceeds to close, your deal doesn't. If the tenant's purchase falls through, the seller can then return to the open market — which may mean returning to you, or starting fresh with other buyers. There's no legal guarantee of your position once a tenant has formally exercised their right.
Does this affect my closing timeline?
If the seller completed compliance before listing — which is the right way to do it — the waiting period doesn't affect your closing timeline at all. If the seller is still mid-compliance when you make an offer, your closing date can't happen until the window closes. Ask your agent to confirm the seller's compliance status before you lock in a closing date.
I'm buying the property to live in one unit and rent the others. Does the ordinance apply to me when I eventually sell?
Yes. When you eventually sell — if the property is still in the covered area and still has tenants — you will be the seller subject to the ordinance's requirements at that time. The ordinance travels with the property, not the ownership.
Questions for Landlords and Investors
If you own rental property in the covered area and are thinking about your options
I own a 6-flat in Logan Square. How long does my compliance process take?
For 5+ unit buildings, the ordinance requires a 60-day notice period and a 90-day tenant response window. That's up to 150 days of pre-sale compliance before you can close with an outside buyer. Start the process earlier than you think you need to.
Can I sell to a family member or investor I know without going through the tenant notice process?
No. The ordinance applies to all sales of covered rental properties, regardless of the relationship between buyer and seller or whether the sale is off-market. A private sale or sale to a related party still requires the formal notice and response period.
What if I want to sell the building without tenants in place — can I just wait for leases to expire?
If the building is genuinely vacant at the time you initiate the sale, there are no tenants to notice and the response period requirements don't apply in the same way. However, deliberately engineering vacancies — allowing leases to expire or pressuring tenants to leave specifically to avoid the ordinance — may create separate legal exposure under Chicago's residential tenant ordinance and other local tenant protections. Consult your attorney on this.
Does the ordinance affect property value or what I can realistically sell for?
In most cases, no — the ordinance affects process and timeline, not price. Buyers who understand the covered area know about the ordinance, factor it into their due diligence, and price offers accordingly. Properties that come to market with clean compliance documentation tend to close just as well as properties elsewhere. Where value can be affected is in situations where non-compliance creates legal uncertainty around the title — which is why getting it right matters.
Do I have to sell at my asking price if a tenant wants to buy?
The tenant's right is to purchase at the asking price stated in the Notice of Intent to Sell — not at a price negotiated between you and a third-party buyer. You set the asking price in the notice, so price it as you would for the open market. If you subsequently reduce the price, you may need to re-notice and restart the response period.
Questions for Tenants
If you've received a Notice of Intent to Sell and are trying to understand your options
I received a Notice of Intent to Sell. What does this mean?
It means your landlord is planning to sell the building and is legally required to notify you first. The notice starts a response window during which you have the right to purchase the building yourself at the price stated in the notice. You are not required to buy — but you have the right to if you can arrange financing within the response period.
How do I exercise my right to purchase?
For properties with 1–4 units, you must provide a pre-approval letter from a mortgage lender within your response window. For 5+ unit buildings, you must provide a letter of intent from a financial institution. A verbal statement of interest is not sufficient to formally exercise the right. Contact a housing counselor or real estate attorney for help navigating this process.
What happens if I don't respond within my window?
If the response window closes without a qualifying exercise of your right to purchase, the landlord is free to proceed with the open market. Your lease rights are not affected — you remain a tenant under your current lease or month-to-month arrangement through the closing and beyond, depending on the terms and Chicago's residential tenant protections.
Can I get help understanding my rights?
Yes. The Metropolitan Tenants Organization and the Chicago Lawyers' Committee for Civil Rights both offer tenant counseling and legal resources for Chicago renters navigating property sales. The City of Chicago Department of Housing also maintains resources related to the ordinance.
Our Experience with 606 TOPA
The Camille Canales Group has represented sellers navigating the Northwest Side Preservation Ordinance, including our most recent transaction at 2913 N. Sacramento Avenue — a 3-flat greystone on the Avondale/Logan Square border with two active tenants. We managed the compliance process before the property launched on the MLS, both tenants received formal notice, neither exercised their right to purchase, and the property closed at $860,000 in May 2025 after 18 days on market.
We know what compliant documentation looks like, we know how to build the compliance timeline into a pre-listing strategy, and we've answered the hard questions at the closing table when documentation gaps threatened to delay other people's transactions. If you have a question that isn't in this FAQ, reach out — we've probably dealt with some version of it.
At a Glance: Required Timelines
