Short answer: A paver patio in Ridgewood, NJ is built on excavated, compacted aggregate base at least 4 inches thick, held at the perimeter by edge restraint, set on screeded bedding sand, and finished with jointing sand between the pavers. The patio also has to slope away from the house and fit within Ridgewood’s lot coverage limits for improvements, which is worth checking before the design is finalized, not after.
Planning a Paver Patio Build in Ridgewood, NJ
A paver patio build in Ridgewood follows the same base construction as anywhere in Bergen County, but two local factors are worth building into the plan early: the Village’s lot coverage limits for site improvements, and drainage on established residential lots where grading and existing landscaping already set the water’s path. Getting both right at the design stage avoids problems after the pavers are down.
A patio looks like a surface project, but the work that determines whether it lasts is almost entirely underground and at the edges, not in the pavers themselves. Excavation depth, base compaction, edge restraint and slope are the four things that decide whether a patio stays flat and drains correctly for years, or starts to settle, heave, or pool water within a couple of seasons.
This guide walks through how we build a paver patio, start to finish, and covers what Ridgewood specifically requires around permitting and lot coverage. It pairs with our paver and stone patios service page, which covers material choices in more depth.
Excavation and Compacted Base
Every patio starts with excavation to design depth and a compacted aggregate base at least 4 inches thick over well-drained soil, per Concrete Masonry & Hardscapes Association guidance for interlocking concrete pavement. A thinner or uncompacted base is the most common reason a patio settles or heaves within a few winters.
Industry guidance calls for a minimum compacted base thickness of 4 inches over well-drained soils, more where the subgrade is soft or saturated. We excavate to that depth and compact the aggregate in lifts, since dumping one thick layer and compacting it once leaves voids that a single pass cannot close, and those voids are exactly where a patio starts to settle unevenly later.
- Excavate to depth. The area is dug out to accommodate the base, bedding sand and paver thickness combined, with extra depth over soft or saturated subgrade.
- Place and compact aggregate in lifts. Aggregate base goes down in layers, each compacted before the next is added, rather than one thick layer compacted once, which leaves voids a single pass cannot close.
- Check grade and slope. The compacted base is checked against the design slope before anything is set on top of it, since correcting slope after the sand and pavers are down means starting over.
Edge Restraint: The Part of a Patio You Never See
Edge restraint is a hidden plastic, aluminum or concrete edging that keeps the outer row of pavers from creeping outward under foot traffic and freeze-thaw movement. Industry guidance calls for at least 1 inch of vertical contact between the restraint and the paver. Without it, joints open and the whole field can drift over a few seasons.
Every paver patio pushes outward slightly under load, and edge restraint resists that push at the perimeter so the field stays tight instead of spreading over time. Concrete Masonry & Hardscapes Association guidance calls for a minimum of 1 inch of vertical restraining surface in contact with the side of the paver.
We stake or anchor restraint into the compacted base itself, not just the topsoil beside it, so it holds through frost heave instead of lifting with it. This is one of the details that is invisible once the patio is finished but is the difference between a field that stays tight for years and one that starts opening at the edges within a season or two.
Bedding Sand, Setting the Pavers, and Jointing Sand
Pavers are set on an uncompacted bedding sand layer 1 to 1.5 inches thick, conforming to ASTM C33, screeded level across the compacted base. Once the pavers are laid, aligned and compacted, joints between them are filled with sand conforming to ASTM C144, typically polymeric sand, in a joint width between about 1/16 and 3/16 inch.
Bedding sand does a narrow, specific job: it lets each paver settle to a uniform, level plane without being compacted itself before the pavers go down. Concrete Masonry & Hardscapes Association application guidance calls for a screeded, uncompacted layer 1 to 1.5 inches thick meeting ASTM C33 grading.
Joint sand does real structural work once it is in place. It transfers load between neighboring pavers, so foot and vehicle traffic is shared across the field instead of concentrated on one paver at a time. Many of our patios use a polymeric version of joint sand meeting ASTM C144 grading, which hardens slightly after it is watered in and resists washout in heavy rain and weed or ant activity in the joints.
Drainage: Getting Water to Shed Away From the House
A patio has to shed water, not hold it. New Jersey’s residential code requires the ground within 10 feet of a foundation to fall at least 6 inches over that distance, and impervious surfaces such as a patio within that band to slope at least 2 percent away from the building. We pitch every patio to match, especially on established Ridgewood lots where existing grading already sets the surrounding water path.
New Jersey’s residential building code requires the grade to fall not less than 6 inches within the first 10 feet away from a foundation, and sets a minimum 2 percent slope away from the building for impervious surfaces such as a patio within that same 10-foot band. A flat or back-pitched patio sends water toward the house instead of away from it, which shows up later as a wet basement or a foundation problem rather than a patio problem.
On an established lot, the patio’s slope also has to work with whatever grading and drainage pattern already exists around the house, which is one more reason a site visit matters more than a generic plan. Where a patio ties into an existing walkway or backs up against the house, see our foundation repair page for how we trace a water problem back to its source.
Ridgewood Permits and Lot Coverage for a Patio
The Village of Ridgewood’s Building Department enforces the New Jersey Uniform Construction Code and local zoning regulations, and Ridgewood’s zoning schedule caps total lot coverage by structures and site improvements as a percentage of lot area, with the exact percentage varying by lot size. A patio counts toward that improvement coverage total, which is worth checking against your lot before finalizing a design.
| Lot area | Max. total coverage by all improvements |
|---|---|
| Under 14,000 sq ft | Lesser of 45% of lot area or 5,600 sq ft |
| 14,000 to 24,999 sq ft | Lesser of 40% of lot area or 8,750 sq ft |
| 25,000 sq ft or more | 35% of lot area |
Ridgewood’s Residential Lot and Bulk Standards summary states these figures for coverage by “all improvements” — the category that includes the house along with site improvements such as patios, walkways and driveways — and directs residents to the full text of the Village’s zoning chapter for definitions and any conditions not captured in the summary table.
Because a patio adds to that total alongside the house itself, driveway and any other hardscape already on the lot, checking your specific zone and lot area before finalizing a patio size is worth doing at the design stage. We confirm scope with the Building Department as needed on a Ridgewood project rather than assuming a patio is automatically exempt from coverage limits.
Maintenance: Keeping a Paver Patio Looking Built-In
A paver patio needs comparatively little maintenance once it is built correctly: periodic sweeping, occasional joint sand top-off as it settles or washes over the years, and resetting any individual paver that shifts. Polymeric jointing sand reduces how often that top-off is needed compared to plain sand.
Because the base and edge restraint are doing the structural work, a well-built patio does not need re-leveling on any kind of schedule the way a poured concrete slab’s cracks eventually do. The main maintenance items are cosmetic: sweeping debris off the surface, rinsing occasionally, and watching for any low spot where water starts to stand, which usually signals a localized settling issue worth addressing before it spreads.
Individual pavers can be lifted and reset if one settles or stains badly, without disturbing the rest of the field, which is one of the practical advantages pavers have over a continuous poured surface.

Frequently asked questions
Do I need a permit for a patio in Ridgewood, NJ?
Ridgewood’s Building Department enforces the New Jersey Uniform Construction Code and local zoning for residential construction, and patio work can be subject to zoning review for lot coverage even when it does not require a full building permit. We confirm the specific requirement for your lot with the Village before starting design, since it depends on your zone and existing coverage.
Does a patio count against my property’s lot coverage limit in Ridgewood?
Yes. Ridgewood’s residential lot and bulk standards cap total coverage by ‘all improvements,’ a category that includes the house together with site improvements such as patios, walkways and driveways, with the maximum percentage varying by lot size. Checking your remaining coverage before finalizing a patio’s footprint avoids a design that does not fit the limit.
How thick should the base be under a paver patio?
Industry guidance calls for at least 4 inches of compacted aggregate base over well-drained soil, with more depth over soft or saturated subgrade. We confirm the exact depth during the on-site inspection, since soil conditions vary from lot to lot even within the same Ridgewood neighborhood.
What is polymeric sand and do I need it for a Ridgewood patio?
Polymeric sand is joint sand with a binder added that hardens slightly once watered in, so it resists washout in heavy rain and slows weed and ant activity between the pavers. It is not required by code, but it holds up better than plain sand and reduces how often joints need to be topped off.
Does a patio need to slope away from the house?
Yes. New Jersey’s residential code requires the grade and any impervious surface within 10 feet of a foundation to slope away from the building, and a patio is no exception. A flat or back-pitched patio sends water toward the foundation instead of away from it.
How long does a paver patio installation take?
Most residential patios take three to six working days depending on size and site conditions, once material is on site. Projects needing extensive excavation, drainage correction, or tie-ins to an existing walkway or steps typically take longer, which is why the written scope breaks those items out separately.
