Permits are the least glamorous part of a hardscape project and one of the parts that catches homeowners most off guard. The dream-up phase is fun. The design phase is exciting. The build phase is satisfying. The permit phase is paperwork, waiting, and occasionally a trip in front of a city board. We will not pretend it is anyone's favorite step. But the difference between a project that lands on time and a project that drags four weeks beyond what was promised is almost always permits, and the difference between a finished hardscape that holds up at resale and one that creates a nightmare at closing is almost always whether permits were actually pulled. Here is the honest picture, by city, of what to expect and how to plan for it.
Permit requirements vary by city. Below is the general picture across the metro. Always verify with your specific city before assuming.
Almost always requires a permit:
Sometimes requires a permit, depends on city:
Usually does not require a permit:
After ten years working across the metro, we have a clear sense of which cities are easy, which are demanding, and which require real time.
Strictest (often require board approval, plat surveys, multiple permits, and HOA approval):
Moderate:
Lighter:
Pattern worth knowing: Kansas-side cities generally have stricter permitting than Missouri-side cities for the same scope of work. Higher-end neighborhoods generally have stricter permitting and HOA layers than mid-market neighborhoods. None of this is universal, but it predicts the timeline reasonably well at the design stage.
Many of our clients live in HOA communities, especially in Leawood, Prairie Village, Mission Hills, and parts of Overland Park. The HOA approval process is separate from the city permit process and often takes as long or longer.
A typical HOA review requires:
Approval timelines run from 1 to 6 weeks depending on how often the HOA committee meets. Some meet weekly, some monthly, some quarterly.
Worst-case scenario we have seen: a client in a Leawood HOA that meets quarterly missed the cycle by 3 days and waited 3 months for the next meeting. We now ask early in the design phase whether a client has an HOA and what their meeting schedule looks like.
What we do: prepare the HOA submittal package as part of our design process. The 3D rendering, the site plan, the materials list, and the technical drawings are all materials we produce anyway. We hand them over in submittal-ready format. We are happy to attend the committee meeting with you if needed.
The honest range, from the day the application is submitted to the day we can break ground.
1 to 2 weeks: simpler permits in less strict cities. A typical paver patio permit in Overland Park or Olathe lands in this range.
2 to 4 weeks: standard residential permit in moderate cities, or a complex permit in lighter cities. Most projects we build fall here.
4 to 8 weeks: strict cities with multiple required approvals, board reviews, or HOA involvement. Mission Hills, Leawood, and Prairie Village projects often hit this range.
2 to 4 months: unusual situations involving variances, easement work, encroachments, or significant non-conforming requests. Rare but real.
The timeline matters because we cannot start the project until the permit is in hand. A patio scheduled for an early-May start with a 5-week permit timeline cannot realistically have shovels in the ground until late April or early May, even if we have the design done in February. We build this into our scheduling and we tell clients up front what the realistic start date looks like.
Permit fees in the metro are usually moderate. The headache is the time, not the cost.
Typical residential permit fees:
A typical project ends up with $200 to $1,500 in total permit fees, depending on city and scope. A large project (pool plus pavilion plus outdoor kitchen plus retaining walls) can hit $2,500 to $5,000 in combined fees.
We typically include permit fees as a pass-through line item in our project cost, billed at actual rather than marked up.
What it costs to skip permits:
The math always favors doing it right. Even the worst-case permit timeline costs less than the cheapest enforcement action.
Standard practice for us on any permitted project.
We handle:
The homeowner handles:
We offer permit handling as a service for projects where the client wants to handle the city paperwork themselves. The fee for our involvement is rolled into the project cost.
A few things that speed the timeline.
Get a current survey. A survey from the past 10 years often satisfies most city requirements. A new survey costs $400 to $800 and takes 1 to 2 weeks. If you do not have one, ordering early avoids a delay later.
Find your HOA documents. Many homeowners forget what their HOA actually requires. Pull the covenants and the architectural guidelines from the HOA's website or board secretary so we know what to design within.
Settle on materials early. Material samples are often required for both city and HOA approvals. Picking the paver, stone, and stain at design time means the submittal package is complete the first time.
Be available for follow-up questions. Cities sometimes have small questions that delay an application sitting on a planner's desk. A 24-hour response to those questions keeps the permit moving.
Avoid major scope changes after submittal. If we have submitted the design to the city and you decide to add a fireplace, we usually have to refile. Major scope changes after submittal can reset the clock.
Do I really need a permit if my neighbors built without one? Sometimes neighbors got away with skipping permits, sometimes they paid fines later, sometimes they have issues we cannot see. Either way, the rules apply to your project. We will not build unpermitted work that a permit is required for.
What if I am replacing an existing patio? Replacing like-for-like (same footprint, same material) often does not require a permit. Expanding the patio, changing materials in some cities, or adding new structures does. We assess every project.
Can a permit be denied? Rarely, but yes. Most denials come from setback violations, lot coverage limits, or HOA restrictions. We design projects to avoid these issues at the start, but if a denial happens we adjust the design and refile.
What is "lot coverage"? Most cities cap how much of your lot can be covered by impervious surfaces (roof, patio, driveway combined). A new patio that pushes you over the limit will not be approved. We check this at design.
What about variances? A variance is a city's permission to do something the code does not normally allow (a slightly oversized retaining wall, an encroaching structure). Variances require a separate process and can take 2 to 3 months. We help clients pursue them when needed.
Will I be inspected during the project? Often yes. Cities inspect retaining walls (drainage, reinforcement), gas lines (pressure tests), and electrical work (rough-in and final). Inspections add no cost and no real delay if the work is built right. We schedule them and meet inspectors on site.
What if I want to start before the permit is approved? We will not start permitted work without the permit in hand. A stop-work order would halt the project and cost everyone more than waiting did.
The right time to start a project that needs permits is earlier than most homeowners think. A project that will break ground in May needs design done by February or March in most KC metro cities, with the permit application going in shortly after design approval. We track the permit calendar for every client and tell you up front what the realistic timeline looks like for your specific city and project.
