Office Interior in Georgia
Partitions, ceilings and finishes for offices and small commercial suites, planned around permits, fire review and accessibility.
An office interior turns an empty or outdated suite into a working space. The core of the job is walls, ceilings and finishes: partitions that divide rooms, a ceiling grid, drywall, paint and the details that inspectors review. Jermaine Enterprises, a general contractor on Greenbriar Parkway SW in Atlanta, builds and renovates interiors for tenants, owners and property managers.
The contractor term is tenant improvement, often shortened to TI. A TI job depends on its paperwork as much as its carpentry: permits, fire review and an occupancy certificate set when the space can open.
Corridors, partitions and fire ratings
Under the 2024 International Building Code, Section 1020.2 requires corridors to be fire-resistance rated per Table 1020.2, and the rated walls must comply with Section 708 for fire partitions. For a Group B business occupancy where the corridor serves more than 30 occupants, the table requires a one-hour rating without an automatic sprinkler system and zero hours with one. The same section lists exceptions, including that no rating is required for corridors in a Group B space that needs only a single means of egress.
Whether a wall in your suite must be rated depends on the occupancy, the occupant load and the sprinkler system, which is why the walls are laid out against the code before they are framed. Rated assemblies must be built as listed, since changing the board, fasteners or joint treatment can invalidate the rating.
Ceilings and finishes
Most office ceilings are suspended grids. ASTM C635 classifies the main tees by load-carrying capability as Light, Intermediate or Heavy Duty, so the duty rating is checked against the weight of tile, lights and diffusers before the grid is laid out. Walls are framed and finished to the level that the paint or wallcovering needs.
Accessibility in a tenant improvement
Under the Department of Justice's ADA regulation, the cost of an accessible path of travel to an altered area is considered disproportionate when it exceeds 20 percent of the cost of the alteration to the primary function area, and the 2010 ADA Standards set the technical requirements. That rule often shapes the budget of a commercial TI. Georgia's Accessibility Code, Rule Chapter 120-3-20, sets state minimum accessibility requirements and uses the 2010 ADA Standards as its baseline, with Georgia-specific modifications.
Permits, fire marshal and occupancy
Requirements are set locally. In DeKalb County, for example, changes to a building require an alteration building permit, plans are reviewed for zoning and life safety, a fire inspection is scheduled after the permit is issued and a Certificate of Occupancy or Completion follows once the required inspections pass. The City of Milton states that any business that changes its occupancy type or performs any renovation must submit plans to the Fire Marshal's Office and the building officials. Fire alarm and sprinkler systems are often reviewed separately from the building plans.
DeKalb County also states that deviating from approved plans requires a permit revision with new plan sets and fees, so scope changes are settled with the permitting office before the work proceeds.

How a job like this runs
Describe the suite
Address, square footage, the use of the space and any plans or a landlord work letter you already have.
Scope, plans and permits
Partitions, ceilings, finishes, rated walls and the permit and fire marshal steps are written into the scope.
Build out
Demolition, framing, board, ceilings and paint proceed in order, with inspections scheduled when the permit calls for them.
Inspect and hand over
Final inspections are requested, punch items are closed and the jurisdiction issues the occupancy certificate once required inspections pass.
What the building department will ask for
Expect to supply plans, the scope of work and, in many cities, a fire marshal review before a permit is issued. Georgia's state minimum codes are enforced locally, and DCA's announcement and city notices give different effective dates for the 2024 editions, so confirm the edition in force with the building department that covers your suite.
Questions about office interior
Do office corridors need fire-rated walls?
It depends on occupancy, occupant load and sprinklers. Under 2024 IBC Table 1020.2, a Group B corridor serving more than 30 occupants needs a 1-hour rating without sprinklers and 0 hours with them, with exceptions such as single-egress spaces. The building's design team and the local official confirm the requirement for each project.
Does an office build-out trigger ADA upgrades?
Alterations to a primary function area can trigger accessible path of travel work. Under the Department of Justice's ADA regulation, that added work is considered disproportionate once it exceeds 20 percent of the cost of the alteration to the primary function area. Georgia's Accessibility Code uses the 2010 ADA Standards as its baseline.
What permits and inspections does a tenant improvement need in Georgia?
Requirements are set locally. Examples show plan submittal to the building department and fire marshal for renovations or occupancy changes, a fire inspection after permit issuance, and a Certificate of Occupancy or Completion after final inspections pass. Check with the specific city or county.
Why does the fire marshal review office renovations?
Renovations can change egress, rated walls, and fire alarm or sprinkler coverage. Examples from other Georgia jurisdictions: Milton requires renovation plans to go to both the Fire Marshal's Office and building officials, and Columbia County reviews alarm and suppression separately from the building plan.
What happens if the plans change during construction?
DeKalb County states that deviating from approved plans requires a permit revision with new plan sets and fees, so scope changes should be settled with the permitting office before the work proceeds.
Verify before you hire anyone. Check any contractor's state license on the Secretary of State contractor board and your city's permit requirements before work starts.
