For estimating purposes you will need about 270sf per person for a typical office suite with
a mix of cubicles and private offices. If you plan a more open office with most staff working in cubicles
you will need less space, about 220sf per person. This will give you your estimated rentable
square feet (RSF).
Space is measured by assignable square feet, usable square feet, rentable square feet,
and gross square feet. Below is a comparison:
Assignable square feet (ASF) is the measurement within the interior walls of a room
or area and does not include interior circulation and common areas (kitchen, copy area, file storage, etc.).
CASPO uses ASF to measure on-campus space – see “Space Data by Department” reports in CASPO’s
SIMS database.
Usable square feet (USF) is the assignable area (ASF) plus interior circulation and common areas.
For estimating purposes, multiply ASF by a factor of 1.40 to get USF.
Rentable square feet (RSF) is the area for which rent is typically charged and is
therefore the number to pay attention to for budgeting purposes. It is the usable area (USF) plus the
tenant’s percentage share of the building’s common areas (lobby space, corridors, restrooms, etc.).
For estimating purposes multiply USF by a factor of 1.16 to get RSF.
Gross square feet (GSF) is the total area, measuring from the outside of the exterior walls and
including all vertical penetrations, such as elevator shafts. It also includes basement space.
This term is seldom used and is provided here for information only.
Leasing costs depend on market forces, location, amount of space required, type of use
(office, lab or clinic) and tenant improvements required/desired. To help estimate lease costs,
please contact the REO Tenant Services
Manager.
There are other costs to consider including, but not limited to, parking, telecommunications, furniture,
moving expenses, equipment insurance, and UW Mailing Services.
See Tenant Responsibilities for more information.
The process on average takes three to six months from CASPO approval to move-in date.
Unique department requirements, market forces, type of use and amount/complexity of tenant
improvements can impact the length of time before occupancy. For details,
please see our sample Leasing Timeline. The REO Project Manager
assigned to your project will develop a customized timeline for your particular project
and update it regularly.
