Room and home additions in San Diego, designed and built by one team.

It depends on the room you add. A great room, kitchen or living room addition may add around 70 percent of its cost to your property value; something smaller, like an extra bedroom, office or bathroom, may add around 15 percent. The size and scope of the project, and the budget you put into it, decide how much the value moves. The bigger return is daily: a home that fits the family in it, and one you did not have to leave.

Building out adds a room on the ground level and is the most common kind of addition. It grows the house's footprint, so a new foundation is poured and some yard space goes to the new room. Building up adds a room, or a whole floor, to the second story, or adds a second story to a one-story house. It keeps your yard, usually needs no new foundation (the existing one may be strengthened to carry the weight) and needs a staircase inside, and your area's rules on house size and height apply. Your designer walks the lot with you and tells you which one the house and the property line allow.

A room addition, also called a bump-out, is usually a single-room structure built onto the house: a bigger kitchen, another bathroom or bedroom, a larger primary suite, a personal office. Added rooms are often built for one purpose, but not always: a combination office and guest room, or a sunroom that doubles as a second living room. It is less expensive than a whole home remodel and adds new life to an older home.

Yes. In-law suites, also called granny flats or accessory dwelling units, can be attached to the house or detached in the yard, and recent changes to state and local legislation have made them easier and less expensive to build on San Diego properties. They add square footage and substantial property value, give parents or guests a private place to stay, and are built with aging in place in mind from the start. Our ADU page covers the types, the rules and what we have built.

Longer than a single room inside the house, and most of the time goes into design, engineering and permits, not construction. Once construction starts, a typical addition builds in about five months; a second story or a complex addition takes longer, and permit review times vary by city within the county. You get the schedule at the bid presentation, and your project manager keeps it live in Buildertrend from the pre-construction meeting on.

Every addition needs a building permit, and local codes restrict how close you can build to your neighbors, the street and even your own backyard. The first step is locating your property lines and developing a plot plan with your home, your landscaping and your utilities on it. Our architects handle that, the design that complements your existing floor plan, and the permit set, and we submit to the city or the county and handle every correction ourselves. One more guideline from twenty-one years of additions: put every detail, every material and the full scope in writing before work begins. That is how bids stay comparable and surprises stay out of the project.
