Warren's residential city certification is triggered by occupancy, not by a sale. Under Section 22.11(a), it's required before anyone occupies a vacant dwelling that has been posted "no occupancy," and it costs $300 on the building division's fee schedule effective April 3, 2024.
A house with a tenant in it falls under a different rule, and the sale itself is what triggers it. The city's rental license is attached to the owner. When the owner changes, the license ends, and the buyer starts the paperwork, the inspection and the debt clearance over from scratch. Anyone pricing a tenant-occupied home in Warren should start from that rule.
The sentence that resets every rental sale
The City of Warren's Rental Inspections Division page spells it out:
"Sale of the subject property results in immediate termination of any license."
The same section says rental licenses "are not transferable between landlords or rental units." A license is good for two years, and getting one depends on passing a biennial inspection under the International Property Maintenance Code. The ordinance also presumes that anyone living in a home other than the owner of record needs a license.
Other cities in the area don't all handle this the same way. Eastpointe's rental program registers and inspects non-owner-occupied homes every two years too, but there a current certificate can carry over to a buyer who registers within 14 days. Warren doesn't offer that carryover. So when you buy a Warren rental, you're buying a house and a tenant. The license isn't part of the deal.
What the new owner rebuilds, in order
Warren revised its rental filing documents in June and July 2026: the license instructions, the application checklist and the application form. The transfer affidavit has to come before the application, and the fees have to be paid before an inspection gets scheduled. Everything in between goes into the application package.
- Transfer affidavit first. If ownership has changed, the owner files a property transfer affidavit with the Assessing Department before applying to Rental Inspections. The owner name on the application has to match Assessing's records.
- One application per address. Every rental address needs its own complete application, printed single-sided. Incomplete applications get sent back. Applications go in person or by mail to the Rental Inspections Division, Third Floor, One City Square, Warren, MI 48093, and the rental address goes in the check memo.
- Entity and tenant forms. An LLC or corporation attaches Form A and needs a current annual report date with Michigan LARA. If the home is occupied, Form B lists every tenant age 18 or older, and every application needs a new Form B.
- ID for each role. The July 15, 2026 checklist asks for the owner's current driver's license, plus a current driver's license or state ID showing an address for the applicant and for the local agent. Passports aren't accepted for the applicant. One person can fill more than one of these roles.
- A responsible local agent. This has to be a person who lives in Warren or within 50 miles of it, and it can't be a tenant. The owner can serve if they meet that requirement. The form makes the legal owner and the local agent both responsible for ordinance violations.
- Fees, then the inspection date. The city won't schedule the inspection until the paperwork is processed and the fees are paid. After that, the house is to be inspected within 30 days of submission.
The out-of-area rule matters most for relocation buyers and second-home investors. An owner living more than 50 miles away needs a local person who meets the residency requirement before the application can be filed.
The inspection is where the price gets decided
The city's posted rental fee schedule, effective March 1, 2023, lists $200 to register a single-family rental and $300 for multi-family. A failed inspection costs $150 if both interior and exterior fail, $100 for interior only and $75 for exterior only. A missed inspection or lockout is $100, canceling with less than 24 hours' notice is $75, and late renewal is $75. These fees are small. The repairs a failed inspection calls for can cost far more.
Warren's rental inspection checklist checks the house against a list of specific standards. Some of them are quick fixes. Others depend on how old the electrical and mechanical systems are.
| Checklist item | Standard | Fix |
|---|---|---|
| Electrical service | Minimum 60-amp service | Panel or service work |
| Furnace power | Separate furnace circuit | Electrical work |
| Kitchen, bath, laundry outlets | GFCI protected | Usually quick |
| Outlets generally | Properly grounded and polarized | Depends on wiring |
| Heat | Occupied rooms hold at least 68°F | Furnace performance |
| Hot water | 120°F | Water heater setting or condition |
| Smoke alarms | Each level, sleeping rooms, and their hallway | Usually quick |
| Carbon monoxide | Detector near bedrooms | Usually quick |
| Windows and doors | Operable window in each room, deadbolts that open without a key | Hardware or window repair |
| Exterior | Sound steps and porches, roof and gutters, no debris or inoperative vehicles | Varies |
The ordinance requires every violation found to be corrected or waived by formal motion of the city council before a license is issued. For a seller, the checklist is a preview of what the buyer's inspector is likely to flag. For a buyer, it's a fixed list of standards that applies to any house they want to rent out.
The parcel's debts have to be cleared too
The checklist covers the house. A second requirement covers the parcel's account with the city. No Warren rental license is issued until these are paid in full: previously billed property taxes, current or past-due special assessments, outstanding water or sewer bills, city charges for mowing, cleanup or debris removal, and any fines or debts under the property maintenance code, blight violations included.
Warren's water service FAQ adds two details. Water bills are a lien on the property they serve, and a change in ownership voids any landlord-tenant water agreement. The city offers a final bill request form that asks for a meter reading and date and takes about one business day to process.
Put those rules side by side and a tenant-occupied sale has more to settle than an owner-occupied one. The new owner can't get licensed while an unpaid water or sewer bill, or any of the other charges, is open on the parcel, and the old landlord-tenant water agreement doesn't carry over to the new owner.
Why the reset carries more weight this fall
In a tight market, a buyer may accept a relicensing project because few other homes are available. Macomb County isn't that tight right now. Realcomp's September 2026 report shows countywide residential and condo inventory at 2,657 homes, up from 2,193 in September 2025 and 1,445 in September 2023. Closed sales fell to 871 in September 2026 from 1,005 a year earlier, while the median sale price rose to $281,500 from $273,750.
Those are county figures, not Warren figures. They still show which way leverage is moving. Prices are up a little, but buyers have more homes to choose from than at any point in the past four Septembers. A buyer comparing a tenant-occupied Warren home with a vacant one, or with a rental in a city that lets the certificate carry over, can count the reset as a cost: a new application, a possible $150 reinspection fee, whatever repairs the 60-amp or furnace-circuit standards call for, and a parcel account that has to be clear before anything is issued.
The rental base those buyers draw on is large. The Census Bureau's QuickFacts estimates that 71.1% of Warren's occupied housing units were owner-occupied over 2020 to 2024, which puts roughly 29% renter-occupied. Median gross rent over the same period was $1,225. Those are multi-year estimates, not current asking rents. They show that a large share of the city's housing goes through this licensing process.
Quick answers
Does the buyer inherit the seller's license if the tenant stays? No. The city's rule says sale "results in immediate termination of any license," and licenses can't be transferred between landlords.
How fast does the inspection happen after the buyer applies? The fee schedule says within 30 days of application, but only after the paperwork is processed and the fees are paid.
Can an owner who lives out of state be the local agent? Only someone living in Warren or within 50 miles can serve, and a tenant can't.
What does the application cost for a two-family home? The current application lists $300 for a two-family dwelling, compared with $200 for single-family.
