Local Intelligence
What St. Petersburg Homeowners Need to Know Before Submitting
Size & Zoning Rules
Accurate floor plans are the foundation of any ADU, garage conversion, or addition permit in St. Petersburg — Construction Services and Permitting will not accept a permit application without them. St. Petersburg's current ADU size cap is 800 sq ft — within the typical range for most floor plan configurations.
St. Petersburg does not impose an owner-occupancy requirement, so you can rent both the main home and any ADU or conversion as investment units.
Homeowners in St. Petersburg who document and legitimize their square footage correctly are positioning a home in a rental market where 1-bedroom units average approximately $1,499/month.
Permit Process & Fees
Construction Services and Permitting 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.
Floor plans submitted to Construction Services and Permitting as part of a permit application must include a site plan, floor plans, all four elevations, an electrical plan, and energy compliance documentation — plus if structural changes are involved, a licensed engineer must stamp the structural drawings.
Visit Construction Services and Permitting ↗Construction Cost Context
St. Petersburg's adu / renovation construction costs run $200–$330 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 St. Petersburg
Because most of St. Petersburg sits inside the FEMA flood zone and coastal overlay district, your ADU plans need a Coastal Development Permit on top of the standard building permit — and that review alone can tack on 3-6 extra weeks before Construction Services and Permitting even looks at your drawings. If your lot is in a older neighborhood like Old Northeast or Historic Kenwood, expect the city to also check your base flood elevation, which often means raising the ADU's finished floor higher than you'd planned, adding real cost to the foundation. And since Pinellas County bans short-term rentals on these units, plan on a long-term tenant or family use only — banking on Airbnb income here just won't fly.
Expert Verdict — Marcus Reid, Licensed Designer
"In my experience, that $250/sqft and 7-week timeline read like statewide averages rather than St. Pete realities—I'd get a couple of local contractor quotes and call Construction Services and Permitting directly before budgeting, since our coastal overlay triggers a CDP review that routinely adds weeks beyond a standard plan check, especially on incomplete drawing sets. What the data also doesn't show is that with STRs off the table here, your ADU pencils out best as long-term rental or family housing, so plan your financing around that use from day one."
Market Context
St. Petersburg has a median home value of $309,000. Comparable renovation projects in this market typically add 25.0% to resale value.
Neighborhoods in St. Petersburg with the strongest renovation and resale value potential include Historic Old Northeast, Snell Isle, Crescent Lake, Downtown / Uptown (Grand Central), Historic Kenwood. High single-family density near downtown and waterfront jobs makes it prime for ADUs.
Permit Process
Permit applications are reviewed by the Construction Services and Permitting, with a plan check timeline of approximately 7 weeks. Permit fees in St. Petersburg range from $2,500 to $10,000 depending on project scope. Design review: Yes - in historic districts only.

Common Questions
St. Petersburg Floor Plan Drafting FAQs
When do I need professionally drafted floor plans in St. Petersburg? +
You need accurate floor plans for: permit applications (required by St. Petersburg's building department for any structural work), refinancing or home equity loans, selling your home (accurate square footage documentation), renovation contractor bidding, HOA design review submissions, and insurance claims. Our as-built drawings capture your home's exact current dimensions.
What is an as-built floor plan and why do I need one in St. Petersburg? +
An as-built floor plan documents your home as it currently exists — including all room dimensions, door and window locations, wall thicknesses, and square footage. These are required when the original permit drawings are unavailable or the home was modified without permits. St. Petersburg's building department requires accurate as-builts when you apply for renovation or addition permits on older homes.
How much does floor plan drafting cost in St. Petersburg? +
Our floor plan drafting packages for St. Petersburg start at $997 for a standard residential home. This includes measured floor plans for all levels, room labels, door and window schedules, and verified square footage. Local drafting services typically charge $1,500–$4,000 for the same work. We deliver within 10 business days with a 14-day money-back guarantee.
How do you create floor plans remotely for my St. Petersburg home? +
You provide basic measurements (room dimensions, door/window sizes) and photos of each room. Our drafting team converts these into accurate CAD drawings with precise dimensions, wall thicknesses, and notations. For permit-grade as-built drawings, we may request additional measurements or a site visit from a local partner. We serve all St. Petersburg neighborhoods remotely.
What format are the floor plan drawings delivered in? +
We deliver drawings in PDF (for printing and permit submission) and DWG/DXF (AutoCAD-compatible format for contractors, engineers, and architects to work from). All drawings are formatted to St. Petersburg building department standards and include title block, scale, and code notations required for permit submission.
Can you draft floor plans for a rental property or multi-unit building in St. Petersburg? +
Yes — we draft floor plans for single-family homes, duplexes, triplexes, ADUs, condos, and small commercial properties in St. Petersburg. Multi-unit buildings are priced based on the total number of units and floors. Contact us for a custom quote if your property has more than 4 units.
Will accurate floor plans increase my home's value in St. Petersburg? +
In St. Petersburg, where median home values are around $309,000, inaccurate or missing square footage records can suppress list price and appraisal value. Professional as-built drawings establish defensible square footage for appraisers and buyers. Unpermitted additions documented and legitimized through permit drawings can recover thousands in appraised value.
Do I need floor plans to get an ADU or addition permit in St. Petersburg? +
Yes — St. Petersburg's building department requires accurate floor plans as part of any ADU, garage conversion, or addition permit application. Our packages combine floor plan drafting with the full permit-ready drawing set (site plan, elevations, electrical, Title 24) needed for plan check submittal. If you only need the floor plans themselves, our Starter package covers that.
Can you draft floor plans from old blueprints or photos in St. Petersburg? +
Yes — we can redraft from original blueprints, scans of old permit sets, hand-drawn sketches, or room photos combined with your measurements. We regularize old drawings to current CAD standards and update them to reflect any modifications made since original construction. This is a common service for St. Petersburg homes built before the 1990s.
