Looking to add a room addition? Congratulations! A room addition in the Tampa Bay Area is an opportunity for you to upgrade your home in a BIG way while adding value at the same time! A question we receive all the time at Home Love Construction is "How much does an addition cost!?" To answer that question, we made the following video:
A few different types of additions we see often are the 1st story master suite, the 2nd story master suite, and the garage addition. Each has its own unique cost structure and considerations in regards to costs, timeline, and size.
1st Story Master Suite:
The most common addition is the addition of a master suite. This typically includes a master bedroom, 1 or 2 walk in closets, and a large master bathroom with a tub & shower (or sometimes a single oversized shower). Building in an open, flat yard area where walls can be adjoined easily to existing walls is extremely cost effective. In neighborhoods fetching over $200/sq ft for housing, most of the time our clients make more back in equity than they spend on construction. Costs for 1st story additions with plumbing and electrical average around $200/sq ft. However, if there is minimal plumbing and electrical costs can be reduced to $175/sq ft or less. Conversely, the more elaborate the plumbing and electrical, the higher the sq ft cost. We have seen 1st floor additions reaching $275/sq ft when using luxury finishes and complicated plumbing/electrical layouts. Projects of this size can vary in length but a typical planning timeline is 2 months to produce plans. Construction can vary between 3-6 months based on various factors including inspections & permitting.
Bottom Line (2nd Story Master Suite)
Cost: $175-$275/sq ft
Planning Timeline: 1-3 months. This includes preliminary plans and construction document production
Construction Timeline: 3-6 months. This varies largely based on the size of your project. Most of our additions are completed within 5 months but inspection periods can delay progress. Allow 1 month for permitting on most major projects.
2nd Story Master Suite:
In the Tampa Bay area, our developers like to build homes EXTREMELY close together! When we don't have room to expand out, we build up! Building a second story room addition is no joke. It involves serious labor, protective precautionary measures, and meticulous planning to ensure the new structure is properly secured to the existing structure. Construction costs on projects of this type start at $200/sq ft and can add up to $275-300/sq ft if luxury finishes are installed. Projects of this type can take extra time to plan and permit because there are lots of stair, egress, and wind load codes to be taken into consideration when planning a 2nd story addition. If you are planning on doing a 2nd story addition, allow 3-5 months for planning & permitting time before construction.
Bottom Line (2nd Story Master Suite)
Cost: $200-$300/sq ft
Planning Timeline: 2-4 months. This includes preliminary plans and construction document production
Construction Timeline: 5-9 months. This varies largely based on the size of your project. Most of our additions are completed within 5 months but inspection periods can delay progress. Allow 1 month for permitting on most major projects.
Garage additions can usually be completed without the amount of finish work required for interior living space. We have had customers add single, double, or even tandem garages to their existing homes. Often, there is minimal electric (lights, garage door, and a few outlets) almost no plumbing, and no wall finish required. This can bring costs of construction as low as $80/sq ft in some cases. In most cases, garage cost of construction is around $100/sq ft. As always, the costs are highly dependent on the specifics of you project.
Bottom Line (Garage Addition)
Cost: $80-$120/sq ft
Planning Timeline: 1-2 months. This includes preliminary plans and construction document production
Construction Timeline: 2-4 months. This varies largely based on the size of your project. Most of our garage additions are completed within 4 months but inspection periods can delay progress. Allow 1 month for permitting on most major projects.
