Pool Permits in Texas, North Carolina and Florida
A backyard pool usually needs more than a building permit. Floodplain rules, setbacks, barriers, electrical and structural plans can all be part of the review.
Rules are set locally, so the city or county where the pool is built decides what the permit package must include.
JRH Engineering is a Structural Engineer, Civil Engineer and Land Development firm serving Texas, North Carolina and Florida.
JRH guiding principles are: Engineering Excellence. Delivered on Time. Built on Value.
What Most Pool Permits Review
Site plan: pool location, setbacks, easements and septic systems
Floodplain: base flood elevation and deck elevation where the lot is in a mapped flood zone
Structural plans: the pool wall cross-section and reinforcement for the site soils
Barrier: fencing and self-closing, self-latching gates per the local code
Electrical: bonding and GFCI protection, designed and installed by a licensed electrician
Drainage: grading so water moves away from the pool and the home
What JRH Engineering Provides
Structural pool design for in-ground pools up to 5.5 ft deep
Retaining walls up to 6 ft where the pool meets sloping grade
Grading and drainage design around the pool and home
