Ann Arbor — Ch. 105 Housing Code § 8:529

(1) Owner's entry into a leased dwelling unit. The owner of a rental, rooming or dwelling unit shall not enter a leased unit unless the following conditions have been met:
(a) The entry is permitted by the terms of the lease.
(b) A good faith effort has been made to notify the tenant in advance.
(c) The owner has knocked on the door and announced the owner's presence at the time of entry; and
(d) The entry has not been refused by a tenant.
In the alternative, an owner may enter a leased unit if such entry is permitted by the lease and if the owner complies with the requirements of subsection (3).
Before leaving the rental unit, the owner shall clean up any dirt or debris from repairs or other activities of the owner and shall lock the unit.
(2) Tenant's right to initiate entry restrictions.
(a) The tenants of any rental, rooming or dwelling unit shall have the right to initiate additional entry restrictions that shall govern entry by the owner into the rented premises.
(b) These restrictions shall be initiated by written notification to the owner, signed by all tenants, of the tenants' desire that entry to the rental unit be governed by the entry restrictions described in subsection (3). The entry restriction shall govern owner's entry into the rental unit commencing on the third day after the request to initiate these restrictions is mailed or hand delivered to the address of the owner as stated in the lease. However, where the owner occupies a dwelling unit within a building, the restrictions on entry to units in that building shall take effect immediately upon delivery of the notice.
(c) The following notice shall be included in the lease or if no written lease provided to the tenant at the time of rental. It shall be in capital letters, bold type not smaller than 14 point. If this notice is not provided as required, the entry restrictions described in subsection (3) shall apply from the commencement of the rental agreement:
NOTICE: YOU HAVE THE RIGHT TO PRIVACY IN YOUR RENTAL HOME. CITY LAW ESTABLISHES GUIDELINES THAT THE OWNER AND HER/HIS AGENTS MUST FOLLOW BEFORE ENTERING YOUR HOME. YOU MAY INITIATE ADDITIONAL ENTRY RESTRICTIONS BY GIVING WRITTEN NOTICE TO YOUR LANDLORD. COPIES OF THESE GUIDELINES (HOUSING CODE 8:529 ) ARE AVAILABLE AT THE BUILDING DEPARTMENT, CITY HALL, 100 N. FIFTH AVE.
(3) Entry restrictions. When the entry restriction provisions of this section have been initiated, the owner of a rental, rooming or dwelling unit shall not enter the unit except when 1 of the following conditions exists:
(a) There is an emergency. "Emergency" means that there is a situation affecting the premises which a reasonable person believes would cause serious damage to property or injury to persons if not repaired or remedied immediately.
(b) The owner desires entry for repairs, maintenance, code inspection, showing the property for sale or lease, appraisals, insurance inspections or such other purposes reasonably related to the operation of the building and the owner complies with the notice requirements of this subsection. An owner entering a unit under this subsection shall mail a notice of the proposed entry at least 5 days prior to the date of entry or hand deliver the notice 3 days prior to the proposed entry. Such a notice may specify more than 1 date for entry within a 10-day period. A tenant may delay the entry specified in the notice by up to 72 hours by notifying the owner/agent in writing or by phone no later than 12 noon on the day prior to the day of the proposed entry.
(c) Any tenant gives the owner written permission to enter the unit for a specific purpose.
When entry is made pursuant to this subsection, the owner shall leave written notice of the date, time and purpose of the entry.
(4) If the tenants of a residential unit request that the exterior locks be changed, the owner shall change the locks so they operate with different keys. The request for lock change must be signed by all of the tenants of the unit and must include a commitment to pay the cost of the lock change as part of the rent. After the receipt of the request, the owner shall modify the lock within 10 days. The modification may permit use of a master key.
