One of the best ways to expand your home is to build up. Let’s break down the cost to add a second story in Los Angeles, CA.
Kitchen and bathroom remodel costs depend on your project and location. Check with a local pro for your specific job.
Building a new entryway addition costs $14,000 to $32,000 for your home, depending on size and scope.
The size of your entryway and whether you need a new foundation or added walls set your total.
Set your budget for site prep and permits, like demolition and approvals, which add $500 to $1,500.
Hiring a local home addition professional helps your entryway get built right and supports value with up to 75% ROI.
In 2026, the national average cost for an entryway addition is $18,000. Most homeowners pay between $14,000 and $32,000, with the size of the addition, foundation requirements, and added wall construction driving the spread. Budget separately for site prep and permits, which run $500 to $1,500.
The cost of all home additions is directly tied to size, and entryway additions are no different. Prices range from $50 to $100 per square foot when converting existing interior space to $225 to $250 per square foot when a new foundation and full construction are required. The conversion approach is the more budget-friendly option, while a ground-up build delivers a fully dedicated entryway without compromising your existing floor plan.
The table below compares average entryway addition costs across five sizes, showing both conversion of existing space and new construction:
| Size (sq. ft.) | Average Cost to Convert in 2026 | Average Cost to Build New in 2026 |
|---|---|---|
| 40 | $2,000–$4,000 | $9,000–$10,000 |
| 60 | $3,000–$6,000 | $13,500–$15,000 |
| 80 | $4,000–$8,000 | $17,000–$20,000 |
| 130 | $6,500–$13,000 | $26,000–$31,200 |
| 180 | $9,000–$18,000 | $40,000–$49,000 |
Hiring a general contractor who builds home additions adds 10% to 20% to your project total, but that cost buys you a single point of contact who hires and coordinates every trade on your behalf. General contractors typically handle foundation pouring, framing, and finishing with their own crews, while subcontracting electrical, plumbing, and HVAC work to specialists. Here’s a breakdown of the cost per square foot for each task:
Cost to pour a foundation: $5–$18 per sq. ft.
Cost to frame your home addition: $4–$16 per sq. ft.
Cost to install drywall: $1.50–$3 per sq. ft.
Cost to install flooring: $2–$25 per sq. ft.
Running electricity to a new entryway for lighting, outlets, and switches requires a licensed electrician, who charges $70 to $120 per hour for labor plus materials. Common entryway electrical costs break down by task as follows.
Installing an outlet: $100–$450
Adding a light fixture: $150–$1,000
Installing a light switch: $60–$300
Architects charge $125 to $250 per hour for entryway addition work, which can include drawing up blueprints, producing as-built drawings for your general contractor, and coordinating with a structural engineer to confirm the addition is sound and code-compliant. Costs vary by deliverable, so the breakdown below covers what each service typically runs:
Cost to draw up blueprints: $250–$5,000
Cost for as-built drawings: $700–$1,300
Structural engineer drawings and approval: $350–$800
Without a general contractor overseeing the build, you’ll likely need to hire individual trade professionals directly, and costs vary widely depending on the scope each specialist handles.
Electrician: $50–$130 per hour
HVAC specialist: $100–$250 per hour
Plumber: $45–$200 per hour
Flooring installer: $2–$25 per sq. ft.
Insulation Installer: $40–$80 per hour
Drywall installer: $1,000–$3,200
Interior painter: $2– $6 per sq. ft.
Window installer: $300–$2,500 per window
[For a home addition], we charge piece-by-piece for the project, then we add our profit and overhead. For example, lumber for the project, permits, demolition, electrical, plumbing, and drywall. I add them up and then add our profit and overhead. On smaller jobs, we work by the hour and then add the material on top of that.
Where you live directly affects what you’ll pay for an entryway addition, since labor rates are higher in areas with a higher cost of living. The table below breaks down the average cost of an entryway addition in different states:
| State | Average Cost in 2026 |
|---|---|
| California | $26,000 |
| Florida | $18,500 |
| Georgia | $16,500 |
| Illinois | $17,200 |
| Michigan | $16,600 |
| New York | $22,200 |
| North Carolina | $17,600 |
| Ohio | $17,100 |
| Pennsylvania | $17,100 |
| Texas | $16,700 |
The location on your property can also play an important role in the cost. If you have a stoop and a concrete walkway leading to your existing front door, for example, you'll pay an additional $500 to $1,500 to demolish them and haul away the debris before construction can begin. Other things to consider include removing trees and making structural changes to your existing home to accommodate the addition.

When building an entryway addition, there are many other cost factors to consider to get the most accurate estimate possible.
Site prep for a new entryway addition is more involved than for a conversion, potentially requiring land grading, landscaping removal, sprinkler line rerouting, and foundation excavation. These tasks can add thousands to your budget before a single wall goes up.
An entryway addition requires a building permit, which costs $200 to $900, and skipping this step can result in fines, work stoppages, or a demolition order for unpermitted construction. If you have questions about what your project requires, check with both your contractor and your local city hall before breaking ground.
A basic entryway is straightforward to build, but adding special features increases costs and can meaningfully improve functionality or first impressions. Practical upgrades like built-in storage and seating serve everyday needs, while options like underfloor heating are more of a luxury investment. Organizing your entryway with the right features goes a long way toward making a strong impression on anyone who walks through the door. Here is the average cost of various entryway accessories and features:
| Accessory or Special Feature | Average Cost in 2026 |
|---|---|
| Custom lighting | $300–$1,100 |
| Built-in storage | $250–$1,400 |
| Custom molding | $400–$2,000 |
| Underfloor heating | $600–$3,000 |
| Ceramic floor tiles | $450–$3,200 |
| Custom doors | $300–$1,000 |
For the most part, adding an entryway to your home isn’t a DIY-friendly task. Considering the extensive skills required to complete this project, including concrete work, framing, roofing, electrical, plumbing, and HVAC, it’s always best to hire a home addition expert near you for help with this project. While these pros add 10% to 20% (or more) to your total, you’ll be glad you made the investment every time you walk through your beautiful new entryway.
There are many reasons to work with a pro on this job, such as:
Getting help with the many different parts of the project, from foundations to roofing
Ensuring a safe, durable, and professional-looking end result
Getting help with the design, building, and finishing processes
Access to work warranties and guarantees
Improved home value due to investing in quality work
Help with acquiring permits
Access to a wide range of tools and skillsets
Support bringing your custom entryway vision to life
While we strongly advise against tackling this entire job yourself, certain parts of the process are safe to DIY:
Hanging new drywall
Painting
Installing entryway flooring
Installing organizing fixtures like cabinets and shelves
Completing other finishing work at the end of the project
You can reduce the cost of adding an entryway in a few ways.
Install energy-efficient windows, insulation, and doors. These will cost more up front, but can save you money on utility bills over time.
Build your own furnishing materials. You could hire a carpenter to build organizational furniture, but consider getting your tools out and flexing those DIY muscles to save.
DIY the finishing work: Speaking of DIYing, consider tackling some of the finishing work, too, like installing flooring and hanging drywall.
Try to recycle or reuse any existing materials. Materials account for 40% to 60% of your total, so every bit saved on materials helps.
Entryways boost your home’s value not only because they add living space but also because they help make a good first impression on buyers who are looking at your house. You could see an ROI upward of 75% on an entryway addition as a result.
Entryways also significantly increase a home's comfort and convenience, which has immeasurable value for many homeowners who aren’t considering selling in the near future.
