Do you need a building permit in Pasco County, Florida?
Unincorporated Pasco County requires a permit for new residential construction, additions, and structural, mechanical, electrical or plumbing work1. The Florida Building Code applies statewide without separate local adoption, subject to statutory exemptions9. Pasco County's owner-builder option is limited to a homeowner working on the homeowner's own primary residence when the property is not a rental, and the county requires an Owner Builder Affidavit and Owner is Contractor Registration Form7. Owner-builder status does not remove the permit requirement for covered work17. Nonresidential farm buildings, farm fences and farm signs on land used for bona fide agriculture can qualify for a state exemption from building-code and local code or fee requirements, but floodplain rules still apply11.
Who is the Pasco County building department, and how do you reach them?
Pasco County Building Construction Services is the county permit office for building work in unincorporated Pasco County1. Reach permit staff at (727) 847-8126 or [email protected]12. The office is at 8661 Citizens Drive, Suite 100, New Port Richey, FL 3465412. Applications may be submitted through PascoGateway, and the county publishes permit packages, checklists, forms, fee materials and a step-by-step application guide1314. Permit prices depend on the work, project size and number of trades; projects that add residential living area can also trigger impact fees15. Ask Building Construction Services for the current total before filing12.
Does Pasco County have zoning?
Pasco County administers zoning and land-development regulations for unincorporated land2. Residential use of an RV is prohibited on property zoned A-C, AC-1, A-R, AR-1, AR-5, AR-5MH, ER-2 and residentially zoned property3. Accessory dwelling units are allowed in districts that allow single-family homes and in qualifying MPUDs, but restrictive covenants, MPUD-specific rules and physical constraints can prevent one10. An accessory dwelling may be no larger than 1,200 square feet, must be smaller than the main house, and must follow the main house's zoning rules for setbacks, height and lot coverage; a mobile home cannot serve as the accessory dwelling10. Reach Planning and Development at 727-847-8140 or [email protected] to confirm the parcel's district, minimum lot size and other site rules16.
How do septic permits work in Pasco County?
Septic permits in Pasco County go through the Florida Department of Health in Pasco County, not the county building office17. Proposed new installations, repairs, modifications and approvals of existing systems require a permit from that health department18. Reach the office at 727-841-4425 or [email protected]; its mailing address is 7509 State Road 52, Hudson, FL 346676. A site evaluation determines whether the property can support the proposed system19. Pasco County health offices continue septic inspections, while an owner or authorized contractor may choose a private inspection provider20. Only about 3.5% of Pasco County soils are rated without severe limits for a conventional drain field, so obtain the site evaluation before assuming a conventional design will work819.
Can you live in an RV or tiny home on your land in Pasco County?
Unincorporated Pasco County prohibits using an RV for sleeping, housekeeping, living quarters or other residential activities on the listed agricultural and residential zoning districts; utility or generator connections create a presumption of residential use3. The restriction can apply even during the day without an overnight stay3. Temporary occupancy is allowed for park trailers in properly zoned campgrounds, RV parks and RV subdivisions4. A nonresident houseguest of an occupant-owner or occupant-lessee may use an RV for up to 10 days, no more than 4 times per calendar year, with at least 30 days between stays on the same property; a Guest RV Parking Permit is required before parking4. Pasco County's tiny-home and minimum-dwelling-size rules remain unconfirmed, so ask Planning and Development about the parcel, structure and proposed use16. A small second dwelling may instead qualify as an accessory dwelling under the county's specific ADU rules10.
Building a home in Pasco County: the steps, in order
- Confirm the land is in unincorporated Pasco County, then ask Planning and Development for the zoning district, allowed use, lot size and setbacks216.
- Determine whether sewer is available; Florida can require connection to an available sewer after written notice, while an onsite system requires a permit and site evaluation211819.
- Use the county's permit package and checklist, then submit through PascoGateway; confirm the project-specific permit and impact fees before filing1315.
- If acting as your own contractor, verify that the home is your primary residence and not a rental, then file the county's required owner-builder forms7.
- Complete the required building and septic inspections; Pasco County health offices continue septic inspection unless the owner or authorized contractor selects a private provider20.
- Obtain the approvals required for occupancy before moving into the completed home22.
What to check before you buy land in Pasco County
Pasco County is largely gentle ground, with 100% of its land at a slope of 15% or less23. The county is not especially remote: population density is about 847.8 people per square mile, and the nearest city of 100,000 or more is about 25 miles from the county center2425. Check wastewater first because only about 3.5% of county soils are rated without severe limits for a conventional drain field8. Verify legal road access and ask the responsible road authority whether a driveway connection permit is needed, because we could not confirm Pasco County's driveway rule. Review flood status with Building Construction Services before designing the house12. Budget for carrying costs: the effective property-tax rate is about 0.8%, the median annual property-tax bill is about $2,028, and the typical annual home-insurance premium is about $2,204262728.
Watch-outs
- Only about 3.5% of Pasco County soils are rated without severe limits for a conventional drain field, so obtain the required site evaluation before assuming a standard system will work819.
- Do not plan to live in an RV on the listed agricultural or residential zoning districts; even daytime residential activity and utility or generator connections can trigger the prohibition3.
