How to Start a Business in Dunwoody, Georgia
Why Dunwoody for Your Business
Dunwoody is not a suburb in any meaningful economic sense. It sits at the center of Perimeter Center — one of the largest edge cities in the United States — with 29+ million square feet of office space, 6 million square feet of retail, and 100,000+ people commuting into the district every weekday morning via I-285, GA-400, and MARTA. That is not a residential neighborhood; it is a concentrated daily economic engine with a built-in customer base and workforce that shows up regardless of what you sell.
The numbers:
- Population approximately 51,900 (DeKalb County). Incorporated December 1, 2008 — one of the newest cities in Georgia.
- Median household income: $121,903. Median age: 37 — younger professional demographic.
- Perimeter Center: 29+ million sq ft of office, 6 million sq ft retail, 40,000+ residents in the district.
Major employers: Dunwoody hosts the Americas headquarters of InterContinental Hotels Group (IHG), plus Insight Global, State Farm, Transportation Insight, and TriNet (relocating to Perimeter). These are your anchor tenants and your B2B prospect list.
MARTA access: Dunwoody Station provides direct heavy rail access to downtown Atlanta — one of the only suburban Georgia cities with rapid transit. This is meaningful for employee recruitment, client accessibility, and real estate strategy. If your employees or customers rely on transit, Dunwoody works.
Edge City 2.0: The city’s 20-year strategic plan focuses on walkability, mixed-use development, and transit-oriented growth around the MARTA station. The High Street development is bringing new retail, restaurants, and residential density to the Perimeter core. Campus 244 and Ravinia office complexes represent the professional services market you will likely be serving.
Perimeter Mall: The second-largest mall in Georgia anchors the retail district. But the real commercial opportunity is in the surrounding office campuses — thousands of professionals working within a 2-mile radius of your potential storefront or service area.
Education pipeline: Georgia State University Perimeter College – Dunwoody Campus provides a local talent pipeline for entry-level and administrative hires.
City Hall: 4800 Ashford Dunwoody Road, Dunwoody, GA 30338. City Manager: Eric Linton. Mayor: Lynn Deutsch.
Choose Your Business Structure
Your legal structure determines liability protection, tax treatment, and annual compliance requirements.
LLC (Limited Liability Company) File online at ecorp.sos.ga.gov for $100, or by mail for $110. Processing: 5–12 business days standard. Expedited: $100 for 2-day, $250 for same-day. Annual Registration: $60/year ($50 fee + $10 mandatory service fee, effective September 6, 2025). Due between January 1 and April 1. $25 late penalty after April 1. Administrative dissolution approximately 60 days past the deadline.
For Perimeter-area professional services firms, an LLC protects personal assets while giving you the tax flexibility to elect pass-through (default), S-Corp, or C-Corp treatment as the business grows.
Sole Proprietorship No state filing required. If operating under a trade name, register your DBA with the DeKalb County Superior Court Clerk. No liability protection — your personal assets are exposed.
Corporation File with the Georgia Secretary of State for $100 online, $110 by mail. Same $60/year Annual Registration requirement.
Note on structure choice: Dunwoody is in DeKalb County — not Fulton County. This matters for DBA registration, county court filings, and certain permit requirements. Many Perimeter-area businesses make the mistake of assuming they are in Fulton County because Atlanta is nearby.
Name Reservation: Georgia allows but does not require name reservation before filing. Fee is $25 if you want to hold a name.

Get Your Dunwoody Occupation Tax Certificate
Every business operating in Dunwoody must have an Occupational Tax Certificate. Regulations are found in Chapter 10 of the Dunwoody Code of Ordinances. Note the spelling: Dunwoody’s official code uses “Occupational Tax Certificate” (with the “al”).

- City Hall: 4800 Ashford Dunwoody Road, Dunwoody, GA 30338
- Main phone: (678) 382-6700
- Business tax inquiries email: [email protected]
- Payments and specific inquiries: [email protected]

The Tax Calculation:
$125 base fee (non-refundable — every business pays this) + First $50,000 of gross receipts: EXEMPT + Above $50,000: taxed at your NAICS-based rate per $1,000 of gross receipts + Per-employee fee (count employees at the Dunwoody location specifically — not company-wide)
The $50,000 exemption is the headline feature. For a brand-new solo business with under $50,000 in gross receipts in year one, your total cost may be just the $125 base fee plus a small per-employee charge. This is exceptionally generous compared to most Georgia cities and makes Dunwoody one of the lowest-cost cities in the state for early-stage businesses.
NAICS code: Your NAICS code appears on your federal tax return and can be looked up at census.gov/naics. It determines your tax class and rate for any revenue above the $50,000 threshold.
Employee count: Count employees at your Dunwoody location specifically. If you have multiple locations, each location’s employee count is calculated separately.
Professional practitioners: State-licensed professionals (lawyers, doctors, CPAs, architects, engineers, cosmetologists, etc.) may elect a flat $400 per practitioner instead of the gross receipts formula, per O.C.G.A. § 48-13-9(c).
New businesses: File within 30 days of commencing business in Dunwoody.
Renewals: Due April 15 each year — two weeks later than Johns Creek’s March 31 deadline. Renewal forms are mailed in early January. If you do not receive your renewal form by mid-January, call (678) 382-6700. Failure to receive a form does not relieve your obligation to pay.
Late penalties:
- 10% of the amount owed
- 1.5% per month interest after April 15
Payment methods: Visa, Mastercard, checks (payable to City of Dunwoody). No phone credit card payments — use online portal or in-person window.
Mandatory Affidavits: Both required under Georgia state law:
- SAVE Affidavit (notarized) + copy of Secure and Verifiable Document (O.C.G.A. § 50-36-1)
- E-Verify Affidavit (O.C.G.A. § 36-60-6): 10+ employees = must register for E-Verify; fewer than 10 = exemption affidavit
Notary services are available at City Hall if you need to notarize your documents on-site.
Zoning, Inspections, and Special Requirements
CRITICAL: Verify zoning BEFORE signing a lease. This is the most important step for any business choosing a physical location in Dunwoody. Email [email protected] with your business address and a description of your business activity before committing to a space. The Zoning Department will confirm whether your use is permitted at that address. Do this before your name is on a lease.
Standard process for commercial locations:
- Zoning Department approval — required before Occupational Tax Certificate is issued
- Fire inspection for commercial locations
- Certificate of Occupancy from Community Development Department (if applicable)
Home-based businesses: Complete the Home Occupation Form. Dunwoody classifies home occupations as:
- Type A: No customer contact at home (online businesses, consultants who meet clients off-site). Standard Home Occupation Form.
- Type B: Customer contact at home (tutors, therapists, personal trainers, etc.). Additional form and more restrictive zoning review.
Food service businesses: Restaurants and food service businesses require a FOG (Fats, Oils, Greases) Compliance Inspection from the DeKalb County Watershed Management Department. This is a DeKalb County requirement — not a city requirement — and it catches food business owners off guard because it is not part of the Dunwoody application packet. Contact DeKalb County Watershed Management separately. Also: a DeKalb County Board of Health inspection is required for food service.
Signage: Signs in Dunwoody are strictly regulated. Contact the Community Development Department before ordering any signage for your business. This applies to window graphics, awnings, monument signs, and directional signs. Ordering $3,000 in signage before getting approval is a common and expensive mistake.
Open for Business
Workers’ Compensation: Required for businesses with 3 or more employees in Georgia (O.C.G.A. § 34-9-2). Secure coverage before your first hire.
Business Networking:
- Perimeter Chamber of Commerce: the primary business organization for the Perimeter Center district. Member directory, events, and advocacy.
- Discover Dunwoody (discoverdunwoody.com): the official destination marketing organization. Can help promote your business to the visitor and resident market through event listings and business directory features.
Perimeter Connects: A free commuter consulting resource for Dunwoody businesses. Helps with parking ratios, alternative commute solutions, and workforce commute analysis. If your business is struggling with employee parking or traffic, Perimeter Connects is the resource.
Alcohol Licensing: Selling alcohol requires an additional license. Contact the Finance Department at (678) 382-6710. Fingerprinting for Alcohol, Massage, Pouring, and Solicitor Permits is done by appointment only at City Hall.
Step-by-Step Launch Checklist:
- Choose your business structure (LLC recommended for most)
- File with Georgia Secretary of State at ecorp.sos.ga.gov
- Get your EIN free at irs.gov/ein
- Register with Georgia DOR at gtc.dor.ga.gov (note: 8% sales tax in DeKalb County)
- Verify zoning at your location BEFORE signing a lease — email [email protected]
- Apply for Dunwoody Occupational Tax Certificate at City Hall or online portal
- Complete Zoning and Fire Department review (coordinated during application)
- Obtain Certificate of Occupancy if commercial location
- For food service: schedule FOG inspection with DeKalb County Watershed separately
- Open a dedicated business bank account and secure insurance
The $50,000 gross receipts exemption means most new businesses in Dunwoody pay almost nothing for their first-year certificate. That is an unusual financial advantage for a city with direct MARTA rail access and 100,000 daily commuters within walking distance.
The Perimeter Center Market: What It Means for Your Business
When people say Dunwoody is home to Perimeter Center, the scale can be hard to visualize. Here is what 29 million square feet of office space actually means in practice:
The daytime population equation: Approximately 100,000 people commute into the Perimeter district on a typical weekday. They arrive in the morning, spend money on breakfast and lunch, need services ranging from dry cleaning to financial planning to technology support, and leave in the evening. For a B2B services business, a food and beverage operation, or a professional services firm, this daytime population is your primary market — and it is one of the most concentrated professional-class workforces in metro Atlanta.
The anchor tenants: IHG Americas (InterContinental Hotels Group), State Farm’s operations center, Insight Global, and Transportation Insight are not just employers — they are procurement organizations. Companies at this scale buy legal services, accounting services, marketing, technology, facilities management, staffing, and more from local vendors. If your business serves corporate clients, Dunwoody’s anchor employers are potential account relationships.
The High Street development: The most visible urban development project in Dunwoody is High Street — a mixed-use complex designed to bring walkable retail, restaurant, and residential density to the Perimeter core. As this development builds out, the foot traffic patterns around the MARTA station and the adjacent Ashford Dunwoody Road corridor will shift. Businesses locating near this corridor now are positioning ahead of that transition.
Campus 244 and Ravinia: Beyond Perimeter Mall and the MARTA station, the office campuses at Campus 244 and Ravinia house professional services firms, tech companies, and financial institutions. These are the B2B ecosystems where relationship-based businesses thrive. If your business model involves building relationships with corporate procurement teams, these are your neighborhoods.
Taxes and Financial Planning in Dunwoody
The DeKalb County sales tax difference: If you are moving from Fulton County or another part of metro Atlanta, pay attention: DeKalb County’s sales tax is 8% (4% state + 4% DeKalb local). Fulton County is 7%. This 1% difference matters for pricing, cash register setup, and competitive analysis if you are in retail. Quote your prices including tax to avoid sticker shock at checkout.
No Georgia city or local income tax: Georgia is one of the few states where local governments — cities, counties — cannot levy income taxes. Your employees pay state income tax (flat 5.19% for 2025, dropping to 5.09% in 2026 under HB 111) and federal income tax, but not a Dunwoody or DeKalb County income tax. This is a straightforward payroll advantage compared to states where employees in major cities pay multiple layers of income tax.
Corporate income tax note: If you form a C-Corporation, Georgia’s corporate income tax rate is 5.75%. Most small businesses use an LLC with pass-through taxation (either default LLC treatment or an S-Corp election) to avoid the corporate-level tax.
Annual Registration: Your LLC or corporation owes the Georgia Secretary of State $60/year in Annual Registration fees ($50 base + $10 mandatory service fee, effective September 6, 2025). Due January 1 through April 1. $25 late penalty after April 1. If you let this lapse and the state administratively dissolves your LLC, you cannot legally enforce contracts or use the LLC name — fix it before that happens.
Professional Services in the Perimeter Market
Dunwoody has an unusual density of professional services demand. The combination of corporate office tenants, high-income residential neighborhoods (median household income $121,903), and proximity to Atlanta’s healthcare and legal corridors creates strong demand for:
Legal services: Corporate and transactional attorneys, employment lawyers, immigration counsel, and real estate attorneys all have natural markets in the Perimeter district. Small boutique practices serving mid-market companies can compete effectively against large Atlanta firms on price and responsiveness.
Accounting and financial advisory: The corporate workforce at IHG, State Farm, and similar employers includes many high-income individuals who need financial planning, tax preparation, and wealth management services. CPA firms and registered investment advisors have a natural client base within commuting distance.
Technology services: IT consulting, managed services, software development, and cybersecurity firms serving corporate clients in the 29 million square feet of office space around Perimeter Center have a dense prospect base. The GSU Perimeter College campus also creates some educational technology and workforce development opportunities.
Healthcare and wellness: The Perimeter market supports a wide range of healthcare providers — primary care, specialty practices, mental health services, physical therapy, and wellness businesses. The resident population’s $121,903 median household income means out-of-pocket healthcare spending is viable.
Georgia requires a state professional license for all licensed professions (medicine, law, engineering, cosmetology, etc.). Obtain your license through the Georgia Secretary of State Professional Licensing Boards at sos.ga.gov/PLB before applying for your Dunwoody Occupational Tax Certificate — the city will require proof of current licensure as part of the application.
