It's every home renovator's dream: You lift a floorboard in the attic and voilà! There are the original blueprints, with dimensions, specs and elevation drawings. The mysteries of your house are solved, and you have a roadmap for repairs and restoration.

For most of us, this is only a dream. In the early 1900s and before, builders rarely drew up the kind of detailed specifications found in modern blueprints.

House construction was largely a matter of convention, using methods passed down by word of mouth. Written manuals and pattern books often contained the hazy instruction, "Build in the usual way."

So, should you give up the hunt? Not yet! Here's how to find answers without tearing up your attic floor.

1. Call Your Realtor

If your house was built in the past 50 years, the sales agents at your real estate office may be able to help you locate facts about its construction. Often they will know the local developers and be familiar with housing styles in your region.

2. Visit Your Neighbors

There's a reason why that house across the street looks familiar. It may have been designed by the same person and built by the same developer. Perhaps it is a mirror image, with minor differences in finishing details. Walking your neighbor's halls can be a good way to learn about the original floor plan of your own home.

3. Consult Your Building Inspector

In most cities and towns around the world, builders must file for a permit before beginning new construction or remodeling an older home. This process ensures some standards of safety for occupants and for the fire company who protects your home. Permits, often with floor plans and elevation drawings, are usually filed in the Building Inspector's office at your local city or town hall.

These documents may not date very far back, but they can be useful for learning about modifications made to your house in the past 20 years or so.

4. Examine the Fire Insurance Maps for Your Neighborhood

While you are at City Hall, ask where you can see the fire insurance maps for your area. In the United States, many fire insurance maps date back to the 1870s. At the very least, these maps will indicate the original construction material (e.g., brick, wood, stone) used for your home. A good bird's-eye view map will also provide a three-dimensional drawing of houses in your neighborhood. Sometimes there is enough detail to show the shape of the buildings and the placement of doors, windows, and porches. Compare your findings with Google Maps.

5. Dig Into the Local Archives

Many communities maintain archives with old photographs, building plans, and maps. These records may be heaped in disorganized piles in the town hall attic—or they may be cataloged and shelved at your local library, museum, or historic commission. If you are lucky, there may be an official city or town historian who can advise you in your search.

6. Browse Historic Plan Books

If your home was built at the turn of the century, there's a good chance the builder drew his inspiration from a pattern book.

In the early 20th-century, many American houses—some surprisingly complex—had humble beginnings as a Sears, Roebuck ready-to-assemble mail order kit. Others followed stock plans published by firms such as Palliser, Palliser and Company. Check out the Sears and Craftsman homes advertised in old magazines and mail-order catalogs.

7. Read Old Advertisements

Simple floor plans for your old house, or houses like it, may have been published in real estate advertisements. Check your public library for back issues of local newspapers. Also, check farm journals and women's magazines for featured building plans.

8. Old House Investigation

The house you're living in may not have started out looking the way it does today.

9. Go Online

Websites like NETR Online run by the Nationwide Environmental Title Research, LLC continue to add public records to their databases. And remember that if you're looking for house plans, chances are that somebody else is, too. Check out some of the forums that still exist online, like Old House Web or My Old House Online. Ask your friends on Facebook, Twitter, and other social networks.

10. Hire an Expert

Blueprints may not exist, but every modification made to your home left behind a trail of evidence. A building professional (usually an architect or a structural engineer) can use field measurements and other clues to recreate the original plans.

Now that you know how your house used to look, the real work begins...renovation!
