If you live in Overland Park and your garage is no longer big enough for your RV, boat, or extra vehicles, you may be considering a serious upgrade.
You have already added shelving. You have reorganized. You still do not have enough room.
Now the question becomes:
Should you add a third car bay to your existing garage?
Should you build a detached garage or RV storage building on your property?
Or would renting enclosed RV storage in Overland Park make more financial sense?
Before you pour concrete or apply for permits, it is worth looking at real construction costs, local zoning rules, and long term financial impact.
National construction data from HomeAdvisor, Angi, Fixr, and RemodelingCalculator.org shows:
Attached garage additions typically cost between $40 and $70 per square foot for basic construction.
Higher end builds often exceed $75 per square foot once finishing, exterior matching, and utilities are included.
Let’s apply that to a common Overland Park scenario.
A single bay addition measuring 12 feet by 22 feet equals 264 square feet.
At $40 per square foot, that equals about $10,560.
At $70 per square foot, that equals about $18,480.
However, that only covers basic framing and structure.
Once you factor in:
Concrete foundation and slab
Roofing tie in
Brick or siding matching
Electrical extension
Insulation and drywall
Permits and inspections
Most Overland Park homeowners end up in the $20,000 to $35,000 range for a properly finished and matched third car garage addition.
And here is the critical limitation.
Most residential garage doors are 8 feet tall.
An RV typically requires 12 to 14 feet of door clearance.
Even after spending $30,000, you may still not be able to store your RV inside.
Before building, you must confirm zoning, setbacks, and HOA restrictions. You must verify:
Minimum side yard setbacks
Rear yard setbacks
Maximum lot coverage
Height restrictions
Drainage compliance
HOA approval requirements
Many neighborhoods in southern Overland Park, especially newer subdivisions, have strict HOA architectural review processes that can delay or deny garage expansions.

If your existing garage cannot be expanded high enough for an RV, you may consider building a detached structure.
National averages show:
Detached garages cost between $50 and $90 per square foot.
High end builds often exceed $100 per square foot.
A 24 foot by 30 foot detached garage equals 720 square feet.
At $50 per square foot, that equals $36,000.
At $90 per square foot, that equals $64,800.
And that does not include premium doors, electrical upgrades, insulation, or finishing.
If you specifically want an RV height building, costs increase further.
Basic shell pricing often runs between $15 and $40 per square foot for materials only.
However, once you add:
Concrete slab at $5 to $8 per square foot
Electrical service at $2,000 to $5,000 or more
Insulation and interior finishing
Grading and drainage
A 16 foot by 45 foot RV building totaling 720 square feet can easily reach $25,000 to $60,000 depending on finish level.
All of this must comply with Overland Park zoning rules and HOA regulations.
Building an addition or detached structure typically involves:
Architectural drawings
Permit approval
HOA review
Contractor scheduling
Three to six months of construction
Weather delays
Material cost fluctuations
Versus renting enclosed RV storage in Overland Park:
Move in immediately
No permits
No inspections
No construction delays
No property modification
Let’s compare real numbers.
If you spend $35,000 on a garage addition, that equals:
Approximately 53 months of enclosed storage at $650 per month.
Approximately 41 months of enclosed storage at $850 per month.
That is more than three to four years of premium RV storage in Overland Park.
If you spend $60,000 on a detached RV garage, that equals:
Over 92 months at $650 per month.
Over 70 months at $850 per month.
That is six to seven years of enclosed, concrete floored, secure storage.
Renting does not increase your property taxes and does not require large upfront capital.
While garage additions can increase home value, they also increase assessed value.

Garage additions typically do not return 100 percent of construction cost at resale. Remodeling industry reports often show 50 to 70 percent cost recoup at best.
Meanwhile, renting enclosed RV storage protects your RV asset without permanently altering your home’s tax assessment.
Building a garage addition or detached RV structure may make sense if:
You plan to stay in the home long term
Your HOA allows large accessory structures
You want workshop space
You value attached convenience over flexibility
You are expanding overall home utility space
For some homeowners, that investment aligns with long term goals.
Renting enclosed storage becomes the more logical option when:
HOA restrictions limit additions
You need 14 foot door clearance
You do not want to tie up $35,000 to $60,000 in construction
You want flexibility
You prefer purpose built concrete floored storage designed for large vehicles
You want to protect a $75,000 to $150,000 RV or boat investment
Expanding your garage in Overland Park can absolutely make sense for some homeowners. If you plan to stay long term, want permanent square footage, and have HOA approval in place, construction may align with your goals.
But if your primary objective is storing and protecting an RV, boat, or oversized vehicle, it is worth looking carefully at the full financial picture.
Spending $35,000 to $60,000 on a garage addition or detached structure requires significant upfront capital. It involves permitting, inspections, construction timelines, and potential increases in property taxes. It may take months before the space is usable. And in many cases, height restrictions still prevent true RV storage.
By comparison, renting enclosed RV storage in Overland Park gives you immediate access to purpose built space with concrete flooring, high clearance doors, and secure access. There are no permits, no architectural reviews, and no construction delays. Your capital remains flexible, and your property remains unchanged.
If you are protecting a $75,000 to $150,000 RV or boat, the goal is not simply adding square footage to your home. The goal is protecting your investment in the most practical and financially responsible way possible.
Before committing to blueprints and contractors, take time to compare the real cost of construction with the cost of premium enclosed storage.
Sometimes the smartest move is not building more onto your house.
It is choosing the right space designed for the job.
