Local Intelligence
What Fort Myers Homeowners Need to Know Before Submitting
Size & Zoning Rules
Any new square footage added to your Fort Myers home counts against the same zoning envelope that governs ADU size, meaning large additions may affect your ability to add a future ADU. Fort Myers's current ADU size cap is 1,200 sq ft — generous enough to accommodate most project types.
Fort Myers currently requires owner-occupancy on the primary parcel — meaning one of the units (the main home or the ADU/conversion) must be your primary residence.
If the addition creates a second unit or is later converted to a rental, Fort Myers's ADU market supports approximately $1,750/month for a 2-bedroom unit.
Permit Process & Fees
Building, Permitting & Inspections (BPI) permit fees for this project type typically range from $2,500 to $10,000 depending on project valuation and scope. Plan check runs approximately 7 weeks — though each correction cycle adds 3–6 weeks, which is why code-compliant drawings matter so much.
Addition permit packages submitted to Building, Permitting & Inspections (BPI) must include a site plan, floor plans, all four elevations, an electrical plan, and energy compliance documentation — plus stamped structural drawings are always required for any load-bearing elements, second-story work, or new foundation.
Visit Building, Permitting & Inspections (BPI) ↗Construction Cost Context
Fort Myers's home addition construction costs run $210–$350 per square foot — a wide range driven by labor markets, local code complexity, and finish level. Our drawings are priced at a fraction of what a full-service architect would charge to produce the same permit set.
⚠ Common Pitfall in Fort Myers
Since most of Fort Myers sits inside the coastal overlay, BPI will require a Coastal Development Permit on top of your standard building permit, and that review alone can tack on 4-6 extra weeks before construction even starts. Because Lee County requires flood-vent and elevation certificates for anything in a flood zone, your ADU's finished floor height often has to match the main house's FEMA base flood elevation, which can force costly fill or piling work if your lot sits low. Also worth knowing: since short-term rentals aren't allowed here, BPI reviewers sometimes ask for a signed affidavit confirming the unit will be used for long-term occupancy only, which can slow down final approval if it's missing from your initial submission.
Expert Verdict — Marcus Reid, Licensed Designer
"In my experience, that 7-week timeline and $300/sqft figure are Fort Myers state-level estimates, not gospel — I'd get local contractor quotes and call BPI directly before penciling in a schedule. And since this parcel sits in the coastal overlay, budget extra months for the CDP review on top of standard plan check; I've rarely seen a coastal ADU clear permitting in under 12-14 weeks once that process kicks in."

Fort Myers enforces minimum setbacks from property lines for all additions: typically 4–5 ft side setbacks and 5 ft rear setbacks, though these vary by zoning district and lot size. Your addition must stay within the buildable envelope. Our site plan documents existing and proposed setbacks and flags any zoning variances required.
Do I need structural drawings for a home addition in Fort Myers? +
Yes, for most additions. Any load-bearing walls, new foundations, second-story construction, or roof structure changes require stamped structural drawings from a licensed engineer. California's CBC (California Building Code) and seismic requirements make structural plans mandatory for most addition types. Our Standard and Premium packages include stamped structural drawings.
