So you are thinking of adding a new space in your home? What an excellent opportunity! When a homeowner wants to add in a new area, generally, this is to either increase the value (by adding square footage) or to accommodate new family living conditions.

Whether you are planning to add in a second story, finish your basement, add a new bathroom, change your garage, or expand one of your rooms, there are essential required steps to help you move forward with your plans. Generally, many new home remodeling projects need the time and care of researching ahead of time. This may include gaining knowledge about the proper building permits and codes, applying for permits, and following inspection procedures.

Brainstorm Home Addition Ideas

Perhaps you are unsure about what type of space you would like to add to your home. This uncertainty is typical when considering your home's location, the amount of property you have, and the functionality of creating a new space. If this is your dilemma, have no worries! Below is a list of possible additional ideas for you and the benefits and considerations for each design. 

Adding a Sunroom 

A nice and simple addition is adding a sunroom. These add a beautiful leisurely component in any room in your home. Sunrooms do need building codes based on county or state, so be sure you have a site plan ready to demonstrate that it meets building requirements. 

Including a House Addition 

Perhaps you want your home to include your children's grandparents, but want them to have a private space. Or, maybe you wanted to add a little cottage or small apartment to rent for others to earn extra income. Each of these examples is a long-term project investment. Obtaining a detailed site and 3D plans may be the best solution to help visualize how you can easily construct a mini-house addition seamlessly.

Remodeling A Attic 

A benefit of remodeling an attic is that it already has a stable structure with flooring and a roof. Additionally, the electrical wiring and additional utilities may quickly transfer offers since they are close to the house's main floor (depending on if it is a two-story or one-story home). Be sure to conduct thorough research on roofing permits, especially if you want to extend the attic height. Additionally, additional flooring material may be necessary to include to limit noise transmission.

Converting A Garage 

Remodeling a garage is by no means an easy endeavor. There is a lot to consider beforehand if your garage location meets the minimum requirements before redesigning. However, if it meets the requirements, you can proceed forward in planning what information you need.

Adding a Pool 

To create a space for more family entertainment, or to increase value, can be made simple by adding a pool. Before you begin, make sure you have the right property landscape and have your questions ready. Also, prepare for having demolition construction workers on your site frequently and limit potential hazards for both you, your property, and their safety. For instance, if there is a tree that could put anyone at-risk at the construction site, you may also need to apply for a tree removal permit. This can all be prepared for in advance by creating the right site plan for a pool!

Once you have chosen what you'd like to add to your home, the next step is to get an approximate budget amount. This plan includes the type of construction materials, types of glass, flooring, or wall choice, and the amount you may need to apply for permits. Luckily, with MySitePlan, you can request a custom site plan of what you would like to include in your new home project, and they can offer an estimated quote of how much it will cost.

Create a Site Plan

You may be wondering, do you need a site plan, or what should I include in a site plan? Suppose you plan on adding new home additions. In that case, you will need a site plan to help you determine the proper dimensions, which permits to apply for (such as mechanical, plumbing, and electrical permits, etc.), as well as verify any zoning or building codes that vary per county. 

Certified vs. Non-Certified Site Plans

You have two options to consider: a certified site plan or a non-certified site plan. An accredited site plan is reviewed by a certified architect, engineer, or surveyor to help you reach the most accurate dimensions. A non-certified site plan, however, does not need a certified individual.  The homeowner, an unlicensed individual, or a company will serve as the organizer of the plan. Depending on the project you are constructing, you may need only to order a non-certified site plan (generally cheaper than a certified site plan).  MySitePlan can help you with measurement adjustments with the aid of satellite data that's free of charge!  However, if your new home addition requires verification from an engineer, for example, be prepared to pay more for the plan.

Selecting a Site Plan

There are many options for you to select a site plan with MySitePlan. There are choices from Basic, Medium, and Detailed. The Basic Site Plan service includes lot lines, north arrows, existing building locations, and dimensions. It is not the best service for building permits, but a great choice if you are seeking to renovate a home! The Medium Site Plan is the most favorable since it includes trees, pools, driveways, and other landscapes, as well as the features from the basic site plan. Finally, the Detailed Site Plan offers commercial and residential use and includes all features from the other plan services. Generally, most people use this plan to apply for a demolition permit, removal of a pool, remodeling, or encroachment issues with neighbors. 

All of these plans can be used when applying for permits; however, be sure to verify that your property or building department does NOT require a plan to be prepared by an engineer, surveyor, or architect to stamp the project.

Include a Construction Permit



Typically, when making any new home renovations, you will most likely follow your county's building regulations and need a permit related to your latest changes. These regulations vary from county to county, so you must reach out to your local building officials before you do construction. It may seem tedious at first, but even the minor home alterations may need a permit. Typically, regional inspection offices will ask for a design blueprint before you can move forward. The inspection process is easier to complete with MySitePlan's online services that typically follow up with you 1 to 2 business days so you can proceed with your project. Be prepared to gain signatures of approval from various members of your community(such as a city planner, zoning officer, or a health local board member), especially if you are creating a new home or pool that may require a septic system. 

Be sure that every new construction on your home has up-to-date building codes to ensure that all safety measures are met.
