Summary
Ann Arbor's Housing Code requires landlords treating an infested rental for pests to notify residents three calendar days in advance and disclose the chemicals used.
Infestation. When treating an infested (see definition, section 8:500) dwelling unit, owners are required to notify residents of treatment 3 calendar days in advance by the following (unless ordered to apply treatment sooner by the housing bureau):(a)When the resident requests management to treat the dwelling unit for a specific pest, no notification shall be required unless the resident requests notification.(b)When management or their employees are going to treat for the eradication of a pest, and when the resident has not requested it, management shall notify the residents 3 calendar days in advance of the treatment.

Full Breakdown
Chapter 105's sanitation provisions require an owner treating an infested dwelling unit for insects, rodents, or other pests to give residents three calendar days' notice before treatment, unless the resident requested the treatment or the Housing Bureau orders faster action. At the time of treatment, the owner must disclose the product name and chemical composition, the treatment date, and any emergency phone number, and keep that record for three days afterward. If a licensed exterminator does the work, the owner must also keep the company's federally required documentation on file for tenants to request. Over-the-counter products may not be sprayed directly on food surfaces or in cupboards, and repeat problems require a licensed pesticide operator.
Violations & Fines
Failing to give the required 3-day pest-treatment notice, or spraying over-the-counter chemicals on food surfaces, violates Chapter 105 and is a civil infraction of $200 to $1,000 under § 8:519(2).
