What does an RV pad actually need?
- 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, concrete, or paver — which surface fits?
| 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 |
What length and width does each RV class need?
- 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
Why does drainage shape matter 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.
Which county, HOA, and zoning items should you 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.

RV Pad Site Prep
RV Pad Preparation in Sacramento
An RV pad is more than a flat spot. It needs level, drainage, a hard surface, the access width to bring the RV in and back it out, and a plan for hookups. Skipping any one of those usually shows up six months later as ruts, standing water, or scraped roof corners.
Roseville ADU Site Prep
ADU Site Preparation in Roseville, CA
Roseville ADUs usually sit on flatter, newer suburban lots — which sounds easy, but the limiting factor is almost always side-yard access. We help prepare the pad, plan the equipment route through the gate, and stage utility trench paths so the foundation crew shows up to a build-ready backyard.
Elk Grove ADU Site Prep
ADU Site Preparation in Elk Grove, CA
Elk Grove lots are mostly flat, mostly clay, and mostly newer suburban builds with side-yard access constraints. The prep job is rarely complicated, but the clay subgrade and the drainage planning are not optional. We help prepare the pad so it stays where it is supposed to after the first wet winter.
