If your lease does not specifically state whether you can sublease or not, you can ask for a Consent to Sublease from your landlord or property manager. This document proves that you have permission from the landlord to sublet the space. You'll want to make sure you get this permission, otherwise you may be found in violation of your lease and risk termination. Your landlord may also have opinions on what types of businesses can move in. Additional items to consider including in a shared space agreement: There are many other things to consider beyond the basic items included in a Commercial Sublease Agreement. Often parts of the space are shared, so you many want to include details that will help all tenants get along and businesses running smoothly. These topics may not have to be in the actual lease, but should be agreed upon. Additionally, some of these items may be in the original lease, so you want to make sure your sub-tenant doesn't cause you to violate the original lease agreement. Shared or communal space This could include lobby space, break rooms, bathrooms, conference rooms, hallways and stairwells, storage rooms and interview rooms. It should be decided how these spaces will be kept clean. You'll also want to include information about how conference and interview rooms can be reserved. Shared equipment Equipment used by multiple renters could include office equipment and break room appliances. Ownership on these items should be established as well as maintenance responsibilities. You can also decide on how new items will be managed. Parking space Most office or retails spaces come with parking spaces. You should define who gets which parking spaces as well as where customers are to park if applicable. Emergency procedures It's important to outline actions that are to take place during an emergency. All tenants should also know where medical supplies and fire extinguishers are located. Signage and advertising You may benefit from saying what kind of signage is allowed and where it can be located. This could include outside signage as well as inside shared spaces such as the lobby. Building alterations This may be included in the main lease and needs to be shared with subletters such as if they can paint or otherwise alter the space they are renting. Visitors If there are restrictions on visitors that information should be shared. It could include children and pet restrictions or anything that violates the original lease.
