Cost Considerations When Adding on to Your Home
When contemplating an addition to your home, there are a host of variables that enter the equation. Calculating a rough estimate is almost as much guesswork for a homeowner as it is a formula. The first step is to decide the size, extent, and type of home addition you are planning. Some of the most popular styles of home additions include:
- Sunrooms and sunporches
- Master Bedroom Suites
- Family Rooms
- Detached Second Living Areas
When estimating costs for a home addition don’t forget to include additional costs that may be related to:
- Local building codes and requirements
- Style and quality of materials and fixtures
- Regional labor costs
- Differences in material costs due to geographic location
- Architectural or Engineering fees required to meet building inspection requirements
Many homeowners expect to realize a gain in the value of their home after doing a home addition. In many cases, this is true. However, some risks associated with this assumption and failing to consider these risks can cost you money in the value of your home in the long run.

In Arizona, you can expect the cost of adding an additional bedroom to a grade-level home to range from $$82 and $130 per square foot. For a 12 x 12-foot standard bedroom addition, homeowners can expect the costs to range between $11,848 and $18,872.

- More ornate or higher-quality trim work, millwork, or custom cabinetry
- Upgraded floor coverings
- Matching exterior finishes to the original home
- Custom closet installations or built-ins
- Extra electronics, electrical, or plumbing required for amenities
Master Bedroom Suite Additions
A special bedroom addition is the master suite. Many older homes have smaller master bedrooms with no ensuite bath or other common amenities in newer homes. Adding an upgraded master suite to an existing home is a great way to add value to the home.
A new master bedroom with an ensuite bath can change the whole character of your home and create a space that enhances your life and enjoyment of your home. The cost of adding a master bedroom with ensuite facilities is more expensive. The need for new plumbing, electrical and a larger space necessitate more costs.
In Arizona, the average cost of adding a master bedroom with an ensuite bathroom entails the addition of about 500 square feet. The average cost to add a master bedroom and ensuite bathroom can cost between $65,185 and $69,565.
The top-end figure of these estimates can go much higher, especially when adding extra amenities for the plan, such as:
- Saunas or steam rooms
- Larger walk-on showers
- Spa tubs
It is not uncommon for a master bedroom addition in Arizona to top the $100,00 mark when several of these specialty items find their way into the plan. However, these types of additions often return 60% of the cost to the home’s value.
Bathrooms – To Add or Remodel?
Whether to add a bathroom or remodel an existing bathroom is a good question to ask. In most instances, either one will add value to an existing home Bathroom remodels tend to be much less expensive than the addition of a new bathroom to an existing home.
It is rare for a bathroom remodel to require moving or adding new plumbing, which keeps the costs more manageable. Adding a new bathroom to a home usually involves much more intensive plumbing, electrical, and HVAC additions.
Estimates for the cost of adding a new bathroom addition to an existing home in Arizona range from $19,804 to $33,973. Just like adding a master bedroom with an ensuite bathroom, the overall cost is tied directly to the quality and number of extra amenities you want to add. Additional amenities such as spa tubs or saunas can push the cost well above our top estimate.
Adding a Sunroom
Sunrooms are popular in Arizona. These additions create a space filled with sunlight. Sunrooms feel close to being outdoors without enduring the oppressive summer heat. Sunrooms are useable as family space, entertainment space, or hobby space.
Sunroom additions in Arizona typically cost between $8,940 to $21,570. The cheaper models are usually kit-style addons that don’t include any plumbing, electrical. Or HVAC. On the upper end are custom-designed additions that include special HVAC to handle the higher summertime loads and specially insulated glass to reduce heating and cooling costs.
Rather than add a family room, many homeowners in Arizona opt to add a detached addition to their home. These detached additions range from sheds or barns to full-featured pool or guest houses.
On the less extravagant end, a shed or barn for extra storage or a garage can be relatively inexpensive. The average cost for adding a detached garage-style structure in Arizona is between $33.88 and $43.56 per square foot. The typical two-car garage costs average between $17,617 and $22,651.
Upscale pool house or guest house additions require much more cost consideration. You are building, for all practical purposes, a brand new home on your site. The typical construction costs for new home construction in Arizona range from $125 – $175 or more per square foot. The average pool house in Arizona is approximately 800 square feet and would cost between $100,000 and $140,000.
New Kitchen Space
As trends in home design change, so do many people’s requirements for their existing home. Often homeowners want to increase the livable space in their home by adding a new kitchen and converting the old kitchen to a more open entertainment friendly floor plan.
Of all the home additions you may consider, adding a new kitchen is probably the most expensive. Adding a basic kitchen with mid-range appliances, cabinets, and countertops are estimated to cost between $27,500 and $60,038.
If gourmet cooking is your passion, you can count additional costs to build and equip a kitchen to fit your needs. Many specialty kitchen additions easily top the $100,000 range. Many times, extensive remodeling of the old kitchen space is also necessary and creates more costs.
Going Up Instead of Out
Most home additions in Arizona involve adding space on the same level as the original home. There are many reasons for this. Perhaps the most prevalent is the number of older retirees who don’t want to climb stairs regularly.
However, there are instances when going up is the only option for adding space to an existing home. Zoning and building ordinances may limit the homes’ size on the lot, which forces any additions to remain in the size of the original home. Some lots don’t lend themselves well because of the terrain to adding same level additions.
Going up with a second story involves a new set of factors and different costs. In general, adding a second story to an existing home involves the cost of:
- Removing the old roof structure
- Adding new framework to the original structure to support the additional weight
- Adding the second-floor framing
- Building a new roof structure
- Remodeling the lower floors to include stairs, new plumbing, electrical, and HVAC equipment.
Costs to go up with a home addition rather than out usually run between $109,887 and $253,454. These costs can fluctuate based on the complexity of the new addition, building codes and fire codes, and current costs for material and labor.
Preparing for a Successful Project
Understanding what you want from your home addition is a key factor in planning a successful project. Working with an architect or home builder ensures that your plan is complete, your estimate is on track, and the project runs smoothly. Adding space to your home can add value and make your home a more inviting and enjoyable place for you and your family.
