Why Two Birmingham Homes a Block Apart Can Owe Completely Different City Bills

Picture two nearly identical brick colonials, one on Oak Avenue and one a few blocks over on a street the city hasn't touched in years. Same era, similar square footage, comparable county assessment. A buyer touring both this fall would have no way of knowing that one of these homes sits inside a special assessment district that Downtown Publications reported the City Commission approved in February, while the other doesn't. The home inspector won't flag it. It won't show up as a defect on a walkthrough. If it surfaces at all before closing, it's usually as a line item on a property tax bill, discovered months after the offer was already signed.

That gap isn't hypothetical in Birmingham right now. The city is running an unusually stacked slate of infrastructure work through 2026, and a meaningful share of it gets funded through special assessments For anyone buying or selling here this year, knowing which side of these project boundaries a property falls on matters nearly as much as knowing the square footage.

A Dense Year for City Work

Birmingham's engineering department is currently managing several overlapping projects, and the timing matters because more than one of them is either under construction or newly assessed in 2026. Wimbleton Drive is split into two phases: Phase 1 runs from Woodward Avenue to Oxford Street and is already under construction for sewer and water main work, while Phase 2 continues from Oxford Street to Adams Road, replacing a six-inch watermain installed in 1925 with new eight- and twelve-inch pipe, with construction scheduled for summer 2026 and coordinated around Derby Middle School's calendar.

Separately, the city is planning to reconstruct North Old Woodward Avenue from Oak Street to Woodward Avenue, with construction bidding this past spring and work set to begin after the August 2026 Woodward Dream Cruise. A sidewalk gap on Quarton Road, from Pilgrim to Lakeside, is being closed as a joint project with Bloomfield Township, running spring through fall 2026. On top of that, the city's 2026 Concrete Sidewalk Program covers Residential Area 2, roughly Adams Road and Woodward Avenue out to the city limits and 14 Mile Road to Maple Road, plus a Downtown Area 1B stretch north of Maple and east of North Old Woodward.

Where the Work Is Happening

The full list of active engineering projects lives on the city's own site and updates as bids are awarded and construction schedules shift, which makes it worth checking against any specific address before assuming a home is or isn't affected.

Two Kinds of "Special Assessment" in One City

Here's the part that catches even experienced buyers off guard. In Birmingham, the phrase "special assessment" can mean two entirely different obligations depending on what kind of property is involved, and they follow different rules.

If the home is a condominium or townhome, like the units along parts of Wimbleton Drive, any special assessment is governed by the association under Michigan's Condominium Act, specifically MCL 559.211. A recent Michigan Court of Appeals decision, Holcomb v. Harbour Pointe Condominium Association, clarified that this statute only requires settling amounts already due at the time of sale. Future assessments the board hasn't yet formally imposed aren't the seller's liability, even if everyone involved suspects one is coming. A buyer protects themselves by requesting a written payoff statement from the association before closing.

If the home is a standalone single-family property, the special assessment instead comes from the city itself, tied to a specific infrastructure project like the ones above. That kind of assessment isn't association business.

A buyer closing on a Wimbleton Drive condo this year could plausibly be dealing with both kinds of assessment at once: one from the association, one from the city.

That's not a scenario most closing checklists anticipate, because most closing checklists are written for one or the other, not both at the same time.

How an Unpaid Assessment Actually Travels With the Tax Bill

Municipal special assessments in Michigan can affect the cost of owning a home, so buyers should check a property's assessment history.

Birmingham's own sidewalk ordinance shows what happens if a bill goes unpaid: a penalty of one percent per month accrues after thirty days, and any amount still outstanding by May gets certified and rolled onto the next annual city tax bill with an additional fifteen percent penalty attached. On a city where the median property tax bill already runs around $10,001 a year on a roughly $712,700 home, a special assessment tucked into that total is easy to overlook until someone actually itemizes the bill line by line.

What the Purchase Agreement Already Assumes

Standard Michigan purchase agreements already anticipate some of this. A common Michigan purchase agreement includes a Municipal Compliances section where the seller agrees to arrange and pay for current certificates of occupancy and sidewalk compliance before closing. Given how much of Birmingham's active work is sidewalk related this year, that clause isn't boilerplate for a Birmingham closing. It's directly relevant to whether a specific address has already been brought up to code or still sits on a punch list somewhere in the city's sidewalk program.

Before You Write an Offer or List

The good news is that this information isn't hidden behind a records request. Birmingham's Treasurer's Office maintains special assessment history by address through BS&A Online, searchable by address, owner name, or parcel number. The City Assessor's office also prepares the special assessment rolls directly and regularly provides that data to local real estate professionals and the public.

Before signing anything, it's worth confirming:

• Whether the property's parcel number appears on any current or recently approved special assessment roll
• Whether the home has a lead service line and, if so, where it stands in the city's replacement queue
• If the home is a condo or townhome, whether the association has discussed or approved any assessment that hasn't yet been formally levied
• Whether sidewalk squares fronting the property have already passed or failed a city inspection this cycle

None of that takes more than a phone call or two, and all of it changes the real math of what a home actually costs to own for the next several years, not just what it costs to buy.

A Few Common Questions

Should I check with the city as well as review the title search? Yes. Checking directly with the city adds a useful check before closing.

What should buyers and sellers check if a project is only half finished when a home sells? Confirming the assessment's status before an offer goes in gives both sides room to address it in writing rather than discovering it at the closing table.

Does living outside the marked project areas mean none of this applies? Not necessarily. Birmingham runs new sidewalk, sewer, and cape seal programs on a rotating basis every year, and this year's list won't be the last. Checking a specific parcel's history is a better habit than assuming a street's past quiet continues indefinitely.

Know Before You Sign

Special assessments aren't a reason to avoid buying or selling in Birmingham. They're a reason to ask a more specific question before doing either. Realty Solutions of Michigan works these details into every Birmingham transaction, checking a property's assessment history and municipal compliance status well before an offer goes out or a listing goes live.
