House Plans and Custom Drafting in St. Petersburg, FL
Service Areas / Florida
The average St. Petersburg home was built in 1972, and more than 42% of the city's houses date to the 1940s through the 1960s (BestNeighborhood and NeighborhoodScout, citing census data). After Hurricanes Helene and Milton, that aging housing stock ran into a hard line: when repair costs exceed 49% of a home's value, the FEMA substantial-improvement rule pulls the entire structure into fully code-compliant, professionally drawn plans. For thousands of Pinellas County homeowners, drafting stopped being optional.
Apex Drafting Services prepares those plans remotely: as-builts, elevation and rebuild sets, remodel and addition drawings, and ADU designs, delivered as permit-ready digital files for submittal to St. Petersburg's permitting office.
Permit activity: a storm-rebuild market layered on an infill market
The baseline numbers first. Census Building Permits Survey data for 2024 shows St. Petersburg authorized 560 single-family units worth $195.3 million, 70 units in two-unit buildings, and 983 units in buildings of five or more, roughly 1,613 units in total. Pinellas County overall authorized about 2,627 units: 1,135 single-family plus around 1,492 multifamily.
Those annual figures understate what is actually moving through the permit counter. Hurricanes Helene and Milton in 2024 generated thousands of repair and reconstruction permits countywide, a volume the annual survey does not break out, and we have not seen an independently confirmed total. To keep that pipeline moving, the city waived permit fees for storm repairs through July 2025.
The substantial-improvement rule is what turns storm repair into drafting work. Cross the 49% threshold and the project must be brought into full compliance with current code, which for many flood-damaged homes means elevation drawings or a complete rebuild plan set rather than a patch. Owners already forced into a full plan set often use the moment to fold in upgrades they had been putting off, from layout changes to an energy-efficient redesign, since the whole structure is on the drafting table anyway.
Old bones, tight lots: what residential drafting looks like here
St. Petersburg is a built-out city. Growth happens through infill, not sprawl, so new single-family plans have to be drawn to a specific existing lot, its setbacks, and its neighbors, not dropped in from a subdivision template. The population backs that up: the 2020 Census counted 259,305 residents, and 2024 estimates put the city at roughly 263,000 to 267,102 (World Population Review and Neilsberg, citing Census Bureau estimates), growth of about 2.4% since 2020 and around 0.6% per year now. The city is not adding land; it is reworking what it has.
That is why most residential drafting in St. Petersburg starts with an existing structure. A housing stock averaging a 1972 build year means measured as-builts, remodel drawings, additions, and elevation sets dominate the workload. Market conditions frame the decision too: Zillow puts the average home value at $374,789, down 0.4% over the past year, while homes still go pending in about 13 days. Owners weighing whether to renovate or move are operating in a market that moves fast but is not appreciating, which tends to favor improving the house they already own.
ADU rules: the city's program sits on top of Florida's statewide floor
Florida is one of the few states with a statewide ADU mandate. SB 184, passed in the 2025 session and effective July 1, 2025, requires local governments to allow at least one accessory dwelling unit on single-family-zoned lots and bars certain restrictive local provisions. Texas and New York have no equivalent statewide requirement; California is the other major state that does. A strengthening bill, SB 48, passed the Florida Senate 38 to 0 in 2026 but died in the House on March 13, 2026, so SB 184 remains the statewide baseline and local governments still set the size, setback, and parking specifics above that floor.
St. Petersburg was ahead of the state. After a July 2022 expansion of its ADU program, roughly 70% of the city's single-family lots qualify, covering the NT, NS, and NTM-1 districts. The rules: a 375 square foot minimum, a cap of 800 square feet or 67% of the primary home's size, and one extra parking space, waived if the lot sits within 1/8 mile of transit. NT lots need at least 4,500 square feet. Our ADU plans and design service works inside that envelope from the first sketch, so the design you fall in love with is one the city can actually approve.
The services St. Petersburg projects actually need
Home Additions & Remodel Drafting
With a 1972 average build year and over 42% of homes from the mid-century decades, most projects here begin with an existing structure that needs updating, opening up, or expanding.
Permit-Ready Drawings & As-Builts
The 49% rule makes documentation step one. An accurate as-built establishes existing conditions, and a code-compliant plan set carries repairs, elevations, and rebuilds through city permitting.
ADU Plans & Design
Roughly 70% of single-family lots qualify under the city's program. We design within the 375 to 800 square foot envelope and the district-specific rules from day one.
Custom House Plans
560 single-family units were permitted in 2024, and substantially damaged homes are being rebuilt from the ground up. Infill lots need house plans drawn to the lot, not to a greenfield template.
Stock House Plans
Starting at $799, stock plans give storm-loss rebuilds and budget-conscious infill projects a cost-controlled starting point, with lot-specific modifications quoted as needed.
3D Renderings & Walkthroughs
When a rebuild means elevating or reshaping a house you have lived in for decades, seeing the design in 3D before permitting makes the hard decisions easier.

St. Petersburg drafting questions
Do I need professionally drawn plans to repair hurricane damage in St. Petersburg?
If your repair costs exceed 49% of your home's value, the FEMA substantial-improvement rule requires the entire structure to be brought up to current code, which generally means fully drawn, code-compliant plans and, for many flood-damaged homes, elevation or full rebuild designs. Below that threshold, requirements vary by project scope, so confirm with the city's permitting office. St. Petersburg also waived permit fees for storm repairs through July 2025.
Can I build an ADU on my St. Petersburg lot?
Roughly 70% of St. Petersburg single-family lots qualify for an ADU following the city's July 2022 expansion, which covers the NT, NS, and NTM-1 districts. ADUs must be at least 375 square feet, are capped at 800 square feet or 67% of the primary home's size, and NT lots need at least 4,500 square feet. One extra parking space is required, waived within 1/8 mile of transit. Statewide, Florida's SB 184 also requires local governments to allow at least one ADU on single-family-zoned lots as of July 1, 2025.
How much home construction is happening in St. Petersburg right now?
Census Building Permits Survey data for 2024 shows about 1,613 housing units authorized in the city: 560 single-family units valued at $195.3 million, 70 units in two-unit buildings, and 983 units in buildings of five or more. Pinellas County as a whole authorized roughly 2,627 units. On top of that baseline, Hurricanes Helene and Milton generated thousands of repair and reconstruction permits countywide, though no precise storm-permit total is broken out in the annual data.
