Property owners in Fresno, CA often look out at their backyard, whether near Woodward Park or down in the Tower District, and consider building an Accessory Dwelling Unit. Before drawing floor plans or choosing tile, property owners must look at the ground beneath the site. Integrity ADU has walked dozens of local properties, and a proper site assessment saves property owners thousands of dollars and many problems later. This guide covers what property owners can check themselves and when property owners need to hire a professional ADU Contractor in Fresno, CA.
Before You Call Anyone: What You Can Check Yourself
Property owners do not need an engineering degree to do some initial reconnaissance on their own property. Grab a tape measure and a notepad.
- Walk your property lines and pace out the distance from existing structures to your fences. Fresno has specific setbacks, usually about four feet from side and rear property lines for detached units.
- Look up your parcel map online through the Fresno County Assessor or City of Fresno GIS portal to spot any public utility easements cutting across your yard. If you build over a main sewer line, the city will tear it down without blinking.
- Check your electrical panel. Go outside, open it up, and look at the main breaker rating. If it says 100 amps, you are almost certainly going to need an upgrade to handle a whole second living space.
During the Project: Keeping Tabs on the Land
Once you have done your homework and brought in an ADU Contractor like Integrity ADU, the site assessment shifts into active problem-solving during excavation and framing. This is where homeowners sometimes try to save money by doing dirt work themselves, and that is a very risky mistake.
Fresno soil can be a very mixed bag. If you are building out in areas with heavy clay or old agricultural hardpan, digging foundation footings requires heavy machinery and specific engineering. Leave the soil compaction tests and grading to the excavation crew. Your job right now is keeping an eye on drainage. Central Valley summer heat is very hot, but when winter downpours hit, water needs somewhere to go besides the base of your new Accessory Dwelling Unit walls.
After the Build: Protecting Your Investment
The dust settles, the final city inspector signs off on the permit, and you have got a brand-new backyard home. Now your site assessment routine changes to maintenance mode.
Walk the perimeter twice a year. Check your gutters and make sure downspouts direct water well away from the foundation. Keep an eye on the grading, especially after heavy rains or landscaping work, because settling dirt can create low spots that trap moisture right against the slab. If you spot a drainage issue or a hairline crack in the concrete, deal with it immediately before it turns into a major structural headache.
