Hardscape planning quiz
Nine questions check the assumptions that most often lead to a settled patio, a leaning wall or an unpermitted structure: base depth, edge restraint, wall height thresholds, fire feature clearances, permeable paver limits, timelines and resale returns. Each answer is explained with a sourced figure so the quiz doubles as a short course before a site visit.

Most hardscape mistakes are made before the first shovel, in the assumptions a homeowner brings to the estimate: that a patio is a surface, that a wall is a stack of blocks, that a fire pit can go anywhere, that the cheapest bid is the same job for less. Houzz's 2026 outdoor study found 41% of projects began because the existing space had deteriorated, which is what those assumptions eventually cost. The nine questions below target them. Get them right and the site visit becomes a conversation between people who both know what matters.
The explanations cite the sources used across the site: HomeAdvisor, Lawn Love and Fixr for cost, NAR and Zonda for resale, the International Residential Code for permit thresholds, the EPA and Virginia Cooperative Extension for permeable systems, and Houzz and CMHA for what the market is doing. HomeAdvisor's install timeline of 4 to 10 days and NAR's 95% recovery figure are two of the numbers you will meet.
What the quiz covers and why
Three questions are about the ground: base depth, edge restraint and what happens when water has nowhere to go. Two are about rules: the retaining wall height at which the model code stops exempting you, and where a wood fire can legally sit. Two are about money: what a modest paver patio recovers at resale and how much more pavers cost than a slab. Two are about the market and timing: how long a professional install takes, and which paver category is growing. None of them asks about color or pattern, because those are the decisions that cannot go badly wrong.
If you miss more than three, read the paver patio page and the retaining wall page before requesting estimates. If you get them all, the calculator and the project brief are the next stops; Houzz found 20% of outdoor renovators hired a stone, paver or concrete specialist, the pro most likely to quiz you back. Either way, the compare tool and the polls are useful for the decisions the quiz does not cover.
How to use your score at the site visit
Houzz's 2026 outdoor study found 71% of renovators hired a professional. Turn each question you found interesting into a question for the professional. If the base-depth question surprised you, ask what depth they use on your soil and why. If the wall threshold did, ask how your city measures height and whether a surcharge applies. If the resale figures did, ask which scope they think matches your street. A pro who answers with dimensions and local rules is showing you their method. The reviews page explains how to confirm that method with references, and the regional notes flag what changes in your part of the country.

Quiz questions, answered
Is the quiz a substitute for a professional site assessment?
No. It tests planning assumptions with national figures and model-code thresholds; a professional assesses your soil, grade, access, water and local rules. The quiz makes that assessment more productive by turning you into someone who asks about base depth and drain outlets. Read the explanations, note the questions that surprised you, and bring them to the site visit.
Why is there no question about paver color or pattern?
Because those choices cannot fail structurally. A color you tire of is a regret; a base you skipped is a rebuild. The quiz spends its nine questions on the decisions that are invisible when the work is done and expensive to reverse. Pattern does affect cost, and the paver patio page explains how curves and diagonals add cuts and waste.
Where do the permit and clearance answers come from?
The retaining wall threshold cites the 2024 International Residential Code as reported by House Digest and DoINeedAPermit.org's 2026 guide; the fire feature clearances reflect common municipal rules and manufacturer listings described on the fire feature page. Local codes vary and often exceed the model code, so confirm with your building department before relying on any threshold.
What should I do if I got the resale questions wrong?
Read both figures. NAR's 95% applies to a modest dry-set paver patio; Zonda's data, summarized by Opendoor, gives about 46% for a larger patio addition. The lesson is to size the patio to the house and to buy fire features and large outdoor rooms for use rather than return. NAR's finding that 92% of Realtors urge curb-appeal work points toward front walks if selling soon.
Can I retake the quiz?
Yes, as often as you like; the questions and explanations do not change between attempts. A second pass after reading the service pages is a reasonable check that the concepts landed. The explanations link to the sources so you can read the original figure and its context.
Does the quiz cover driveways?
Indirectly, through the base-depth and permeable paver questions. Driveways need 10 to 12 inches of base and 80-millimeter pavers, and permeable systems are most relevant where runoff to the street is regulated. The walkways and driveways page has a table comparing walk and driveway specifications side by side.
How do I use the quiz results in the project brief?
List the questions you want the professional to answer for your site: base depth on your soil, wall permit threshold in your city, allowed fire fuel and setbacks, whether permeable pavers suit your drainage. Put them in the brief on the contact page. A pro who addresses them specifically in the proposal has demonstrated the method that keeps hardscape level and dry.
