Quick Answer
Is there new construction in San Antonio FL?
New construction directly in San Antonio FL is limited because the community has no active master-planned developments. Production builders operate primarily in nearby Zephyrhills (D.R. Horton, LGI Homes, $280K-$420K range) and Wesley Chapel (multiple builders, $380K-$950K+). In San Antonio proper, new construction means custom building on vacant land through Pasco County permitting. This requires more work but gives buyers full control of design and land use.
Why San Antonio FL Has Limited Production Builder Activity
San Antonio FL is a small rural community without the large parcels available for master-planned community development. Production builders like D.R. Horton and Lennar prefer to acquire hundreds of acres to develop subdivisions with amenity centers, trails, and staged phases. San Antonio's character, with primarily smaller acreage parcels and proximity to Saint Leo University, does not support that model.
What exists in San Antonio is a genuine rural community where new homes must be custom built on individual parcels, or buyers must look at nearby growth markets for production builder options.

Building a Custom Home in San Antonio FL
Step 1: Find and Secure the Right Parcel
Custom building starts with land. In San Antonio, lots vary from small rural parcels to large agricultural tracts. Before making an offer on land, verify zoning (AR-1, AR-2, or RSC are common), confirm that a perc test passes (required for septic approval), and understand road frontage requirements for Pasco County building permits.
Step 2: Perc Test and Septic Design Approval
Because San Antonio has no municipal sewer, the Florida Department of Health in Pasco County must approve your septic system design. This starts with a percolation (perc) test conducted by a licensed engineer. The soil absorption rate determines what type of septic system is required. Budget $500-$1,500 for the perc test.
Step 3: Well Permitting
Private wells require a water well permit from the Southwest Florida Water Management District (SWFWMD). A licensed well driller sinks the well to reach the Floridan Aquifer, typically 80-250 feet in this part of Pasco County. Well drilling costs $6,000-$18,000 depending on depth, casing, and pump size.
Step 4: Building Permit Through Pasco County
Pasco County Development Services processes residential building permits. Submit plans, pay the plan review fee, and wait for approval before breaking ground. Pasco County has improved permit turnaround times but expect 4-8 weeks minimum for new construction plan review.
Step 5: Construction and Inspections
Pasco County requires inspections at multiple phases: foundation, framing, rough electrical, rough plumbing, insulation, and final. Your contractor schedules inspections through the Pasco County permit portal. Final occupancy permit (CO) is issued after all inspections pass.
