What an RV pad actually needs
- Level surface (or a controlled slight slope for drainage, not for parking)
- Drainage shape so water moves away from the pad and the structure
- Hard surface — gravel, concrete, or pavers — sized for the loaded weight
- Access width and turning radius to bring the unit in without scraping fences, eaves, or trees
- Length matched to the unit plus tongue, slide-outs, awnings, and a walk zone
- Hookup planning for electrical, water, sewer/holding-tank dump, and propane
- Compliance with HOA, county setback, and zoning rules before the pour or compaction
Gravel vs concrete vs paver
| Surface | Best Fit | Planning Range |
|---|---|---|
| Compacted gravel (Class II base) | Most rural and side-yard pads, lowest cost, easy drainage | $3,500-$8,000 for a typical pad |
| Reinforced concrete slab | Long-term storage, heavy units, year-round use | $8,000-$18,000+ depending on size and rebar |
| Permeable paver | Aesthetic pads in view of the house, HOA-friendly looks | $10,000-$22,000+ depending on paver and base |
| Hybrid (concrete tire tracks + gravel center) | Compromise between cost and stability | $5,500-$11,000 |
Length and width by class
- Class A motorhomes: plan for 40-45 ft length plus 5-10 ft buffer, 12-14 ft pad width plus slide clearance
- Class C and small motorhomes: 28-35 ft length plus buffer, 11-12 ft width
- Fifth-wheels and travel trailers: 32-42 ft including the tongue, 11-12 ft width plus slide-outs
- Toy haulers: add 8-12 ft for the ramp drop-down zone behind the unit
- Always check the door, awning, and slide-out side — the pad must clear those when fully extended
Drainage shape matters more than "flat"
A truly flat RV pad ponds water on the first rain and creates a mud line right where the steps go. The right shape is a 1-2% cross-slope away from the structure and the access door so water sheets off the pad surface, plus a drainage swale or French drain on the high side if the pad is cut into a slope. Sacramento valley clay soils especially benefit from a defined drainage path under the gravel section so the pad does not soften in winter.
Access and the rest of the driveway
The pad is the easy part. The harder part is usually getting the RV from the street to the pad. Plan for the turn radius (40-45 ft RVs need a wide approach), low-hanging branches, eaves, gate widths, and the slope change between the driveway and the pad. We often add a transition apron between the existing driveway and the new pad so the RV does not bottom out at the lip.
County, HOA, and zoning items to confirm
- Setback from the property line and from any structure
- Surface-material restrictions in HOA neighborhoods
- Visibility / screening rules for RV storage in some zoning districts
- Permit requirements for grading volume, retaining walls, or permanent slabs
- Sewer dump connection requirements if a holding-tank dump is part of the scope
Frequently asked questions
- How much does an RV pad cost in the Sacramento region?
- A gravel RV pad usually runs $3,500-$8,000. A reinforced concrete slab runs $8,000-$18,000+ depending on size and rebar. Permeable pavers can run higher. The driveway access and any drainage work are usually scoped separately.
- What size pad does a 40-foot RV need?
- Plan for a 45-50 ft pad to give buffer at both ends and 12-14 ft of width so slide-outs and the awning extend without crossing the edge. Always confirm the actual measured length of your unit before pouring concrete.
- Do I need a permit for an RV pad?
- Gravel pads with no retaining wall and minor grading often do not need a permit, but every jurisdiction has its own threshold. Concrete slabs, retaining walls, and sewer connections usually do. We will confirm before scheduling work.
- Can the pad be on a slope?
- The parking surface itself should be near-level (1-2% cross-slope only). If the natural ground slopes, we usually cut into the slope, build a retaining edge on the high side, and shape drainage so runoff does not pond on the pad.
