If you’re hoping to find plumbing blueprints for your house, there are a few places you can look. First, check with your city or county planning office. They may have records of the original blueprints for your house on file.
If not, they may be able to direct you to the right place. Another option is to contact a professional plumber in your area and ask if they would be willing to take a look at your house and provide you with a copy of the blueprint. Finally, if all else fails, try searching online – there are many websites that sell copies of old house blueprints.
7 Effective ways to locate Plumbing Blueprints
- Check Your Home Documents
Start by looking through paperwork you received when buying the home—building permits, floor plans, and construction documents may include plumbing drawings. Sometimes, previous owners or builders keep these files. - Contact the Builder or Developer
The construction company that built your home or carried out renovations usually retains copies of plumbing plans submitted for approval. Reaching out to them can yield the exact blueprints. - Visit Local Building or City Council Offices
Most local governments keep records of building permits and plans for approved new constructions or modifications. You can request copies of your plumbing plans from the city or municipal building department. - Talk to Your Plumbing Contractor
If the builder does not have the plans, the plumbing company involved in your home’s installation might have retained records or can offer insight into your plumbing layout. - Hire Professional Services (CCTV Inspection)
If plans are lost or outdated, plumbers can scan and locate pipes with specialized cameras underground or behind walls. This creates an accurate map of your home’s plumbing as it exists now. - Use Online Resources or Blueprint Services
In some regions, you can search online databases for building plans or hire professional blueprint scanning companies to obtain digital copies. - DIY Blueprint Drawing (If No Plans Are Found)
If no official plans are available, you can create your own plumbing map by tracing visible pipes, water shut-off locations, fixtures, and venting routes.
