You've decided it's time to renovate. Maybe the kitchen is outdated, the bathroom needs work, or you're thinking about adding an ADU in the backyard. Whatever the project, there are a few things worth checking before you start calling contractors for quotes.
This isn't about doing the work yourself — it's about walking into that first conversation informed. Contractors respect homeowners who've done their homework, and you'll get better estimates because of it.
1. Know Your Property Lines
This sounds basic, but you'd be surprised how many homeowners aren't sure exactly where their property ends. If you're planning an addition, ADU, deck, or any exterior work, setback requirements matter. Pull up your property survey or check your city's GIS map online. In Arcadia, the Development Services department can help you understand your lot's specific zoning.
2. Check Your Electrical Panel
Open your breaker box and take a photo. How many amps is your main panel? Is it a modern breaker panel or an old fuse box? If you're planning a kitchen remodel or ADU, you might need a panel upgrade — and that affects both timeline and budget. Most SGV homes built before 1980 have 100-amp panels. Modern renovations often require 200 amps.
3. Look Under Every Sink
Water damage is the silent budget-killer of renovations. Get a flashlight and look under every sink in your home — kitchen, bathrooms, laundry. Check for moisture, stains, soft wood, or musty smell. If you find active leaks or old water damage, mention it upfront. A good plumber needs to know what they're walking into.
4. Test All Your Outlets
Grab a $10 outlet tester from Home Depot and test every outlet in the rooms you plan to renovate. Check for proper grounding, reversed polarity, and dead outlets. This gives your contractor (and their electrician) a head start on understanding your home's wiring situation.
5. Photograph Everything
Before your first contractor visit, photograph every room, wall, corner, and angle of the space you want to renovate. Include close-ups of problem areas — cracks in walls, uneven floors, peeling paint, old fixtures. These photos serve two purposes: they help the contractor give a more accurate estimate, and they protect you by documenting the "before" state.
6. Check Your Home's Age and Previous Permits
If your home was built before 1978, there's a chance of lead paint. Before 1985, asbestos in flooring or insulation is possible. Both require special handling during demolition and add cost. You can check your home's permit history through your city's building department — this also reveals whether previous work was done with or without permits.
7. Research Your City's Permit Requirements
Different SGV cities have different requirements. Arcadia, Pasadena, and San Marino each have their own plan check process and timelines. Knowing whether your project needs a permit — and roughly how long your city takes to approve them — helps you set realistic expectations.
8. Set a Realistic Budget Range
Don't go into a contractor meeting saying "I have no idea what this costs." Do 30 minutes of online research first. A mid-range kitchen remodel in the SGV runs $35,000–$65,000. A bathroom remodel is typically $15,000–$35,000. An ADU can be $150,000–$300,000+. Having a ballpark helps the contractor tailor their recommendations to what makes sense for you.
9. Write Down Your Must-Haves vs. Nice-to-Haves
Before that first meeting, make two lists. Column A: things you absolutely need (more counter space, a second bathroom, better lighting). Column B: things you'd love but could live without (heated floors, a pot filler, smart home integration). This helps the contractor prioritize and keeps the conversation focused.
10. Verify the Contractor's License
California makes this easy. Go to cslb.ca.gov and enter the license number. You'll see their name, license classification, bond status, and whether any complaints have been filed. If a contractor won't give you their license number, that's your answer.
For the record: ours is CSLB #1150423. Feel free to look us up.
The Bottom Line
None of this takes more than an afternoon. But showing up to your first contractor meeting with photos, a budget range, permit awareness, and a clear list of priorities? That changes the entire dynamic. You'll get better estimates, faster timelines, and a contractor who knows you're serious.
And if something feels off during that first conversation — trust your gut. A good contractor welcomes informed homeowners. The ones who don't? Keep looking.
