Change of Use — What It Triggers

A clothing store becomes a cafe. A salon becomes a yoga studio. A retail shop becomes a bar. To you it’s a new business; to the building code it’s a change of occupancy classification, and that change can trigger code upgrades far more expensive than the rent itself. This page tells you what to look for.


When you see…It means…
Occupancy classificationA code-defined category for what kind of activity happens in a space (retail, restaurant, office, etc.). Listed on the building permit history.
Change of UseWhen you switch from one occupancy classification to another, even with no construction.
Change of TenantNew business in the same use category (clothing store → bookstore). Simpler review.
CO (Certificate of Occupancy)The city document that says a space is legally OK for its stated use. You need a new CO for a change of use, and you can’t legally open without one.
AlterationConstruction work that changes a space without changing its use — different review path.
Adaptive reuseRe-purposing an old building for a new use, often involving change of occupancy plus historic preservation review.
EgressThe way people get out — number of exits, exit width, travel distance to an exit.

The NC Building Code (which mirrors the International Building Code) groups uses into letter-coded categories. The ones most relevant to downtown:

CodeGroupExamples
A-2Assembly — food/drinkRestaurants, bars, banquet halls, coffee shops with seating
A-3Assembly — recreation/worshipYoga studios, art galleries, churches, lecture halls, museums
BBusinessOffices, banks, professional services, salons, small medical
MMercantileRetail stores, boutiques, markets
R-1Residential — transientHotels, B&Bs, short-term rentals
R-2Residential — multifamilyApartments, condos
SStorageWarehouses, self-storage

Within each letter, sub-numbers (A-2, A-3, A-4) carry different requirements. The further apart two classifications are on the hazard scale, the more upgrades a change between them can trigger.

Old use → New useRisk levelWhy
B / M → A-2 (any → restaurant)HighRestaurant is treated as higher-hazard assembly use. Likely triggers sprinklers, hood, grease trap, restroom upgrades.
M → A-3 (retail → yoga, gallery, event space)Medium-HighAssembly use brings stricter egress and occupant-load rules.
B → M or M → B (office ↔ retail)MediumUsually simpler, but plumbing fixture counts and parking can still come into play.
R → anything commercial (apartment → store)MediumDifferent fire separation, accessibility, and structural rules.
Same letter (clothing store → bookstore = M to M)LowOften just a Change of Tenant review — no upgrades unless space is being substantially altered.

The NC Building Code, NC Fire Code, and ADA Standards each have their own triggers. A change of use evaluates against all of them.

Triggered when:

  • New use places more occupants in the space than the old use was designed for
  • New use is in a higher-hazard category (A-2 restaurant is the classic example)
  • Building height, area, or fire-resistance ratings no longer meet code for the new use
  • Mixed occupancies that exceed code-defined limits for non-sprinklered buildings

Cost reality for downtown: retrofitting sprinklers in an old historic building is among the most expensive upgrades possible. Older buildings often have low ceilings, plaster walls, no central core for risers, and water-supply lines that need upsizing. Budget conservatively.

Kitchen exhaust hood + fire suppression (NFPA 96)

Section titled “Kitchen exhaust hood + fire suppression (NFPA 96)”

Triggered when:

  • Any commercial cooking that produces grease-laden vapors (frying, grilling, broiling, charbroiling)
  • Type I hood required for grease cooking; Type II for steam/vapor only

What’s involved: stainless-steel hood, ductwork to roof, makeup-air unit, ANSUL (or equivalent) wet-chemical fire suppression, gas/electric shutoff interlocks. All of this is permit-and-inspection work. Lead time on hood fabrication alone can run 6–12 weeks.

Triggered by any food preparation that puts fats, oils, and grease into the wastewater. PWC (Fayetteville Public Works Commission) sets sizing requirements based on number of fixtures and food type. Required before sewer connection — not optional, not retrofit-able later without ripping up floors.

Restroom count and accessibility (NC Plumbing Code + ADA)

Section titled “Restroom count and accessibility (NC Plumbing Code + ADA)”

Triggered when:

  • New use changes occupant count beyond what current restrooms support
  • Building is being substantially altered such that ADA “readily achievable” barrier removal kicks in
  • Old restrooms don’t meet ADA Standards 2010 (door width, turning radius, grab bars, fixture clearances, signage)

Common surprise: an old downtown building has one tiny restroom that worked for an office of 4 people. Your cafe with 30 seats may need two restrooms (men/women) AND ADA compliance for both.

Triggered when:

  • Higher occupant load needs more or wider exits
  • New use changes the path-of-travel calculations
  • Non-conforming stairs, doors, or hardware no longer meet current code

Look at: exit width, exit count (typically two required for assembly use), door swing direction, panic hardware, illuminated EXIT signs, emergency lighting.

Triggered when:

  • Substantial alteration affects building envelope, lighting, or HVAC
  • New construction must meet current NC Energy Conservation Code

Often triggers LED lighting upgrades, additional insulation, upgraded HVAC efficiency.

Triggered when:

  • New use places higher loads on the floor system (e.g., assembly load with chairs/people > office/retail)
  • Rooftop equipment (large HVAC, makeup-air units) increases roof loads

Old downtown buildings often have wood-joist floors that pre-date current load standards. A structural engineer’s letter is sometimes required.


The Change of Tenant / Change of Use / Change of Occupancy Classification Application is a single form on the Fayetteville e-Development Portal. Here’s the typical flow:

  1. Pre-submittal call (free) — call Development Services at 910-433-1707 with the address and intended use. They’ll tell you what reviews and upgrades are likely needed.
  2. Submit application in the e-Development Portal — see the IDTplans Portal Guide for how.
  3. Plan review — Development Services + Fire Marshal + (if applicable) Historic Resources review the plans. Often returns with comment letters listing required changes.
  4. Permits issued for any construction needed.
  5. Construction & inspections — rough-in inspections, then finals.
  6. Certificate of Occupancy — issued only after all inspections pass.

Typical timeline:

ScopePlan review onlyPlan review + construction
Simple change of tenant (same use category)2–4 weeks4–8 weeks
Minor change of use (cosmetic + minor work)4–6 weeks8–12 weeks
Full change of use (e.g., retail → restaurant)6–10 weeks4–9 months

Project typeWho can prepare the drawings
Cosmetic only (paint, fixtures, no walls)Owner or any qualified person
Change of tenant, no constructionOwner or designer
Minor alterationDesigner; sometimes architect or PE depending on size
Change of use with significant alterationLicensed NC architect or professional engineer (PE)
Anything involving structural changesLicensed PE for the structural drawings
Historic district exterior changesArchitect familiar with NC SHPO + Historic Resources review

NC law requires sealed (architect or PE) drawings for most projects above certain thresholds. The reviewer at Development Services will tell you which seal is required.


The previous tenant was the same kind of business as me. Do I still need a change-of-use review? Usually no — that’s a simpler Change of Tenant review. But: the city verifies that the previous use was actually permitted (sometimes spaces operate informally). Confirm at 910-433-1707 with the address before assuming.

The building has a current CO. Doesn’t that mean it’s good to go? The CO is for the previous use. A change of use requires a new CO for your use. Until that’s issued, you cannot legally open.

Can the landlord absorb the upgrade costs? Negotiable — and worth pushing on. Landlords often offer a Tenant Improvement (TI) allowance to cover code upgrades, especially in a soft leasing market. The TI clause needs to be in the lease before you sign.

What if the building has historic-district status? Historic Resources Commission (HRC) reviews exterior visible changes — facade, signs, mechanical equipment locations, window changes, awnings. Interior change of use is governed by the Building Code, not HRC, but if your interior change requires exterior modifications (new exit door, hood vent on the roof), the exterior portion goes to HRC. Add 2–4 weeks to the timeline.

Can I open under the old CO while the change-of-use review is in progress? No. Operating under the wrong occupancy classification is a code violation. The city can issue a stop-work order and fines, and your insurance may deny claims.

Are there exemptions for very small changes? Some minor changes don’t formally trigger a “change of use” determination — for example, an office category B becoming a slightly different B use. The reviewer at Development Services makes the call. The cheapest review is the phone call before you sign anything.

What if I’m a tenant in a multi-tenant building? Your change of use can ripple — adding a restaurant to a building of offices may push the whole building over a code threshold (e.g., requiring sprinkler retrofit of the entire building, not just your space). Get this clarified early.
