How to Prepare Your Property for ADU Construction

Getting Your Property Ready for ADU Construction

You've gotten your permits approved. Construction is about to start. But is your property ready? Proper preparation prevents delays, reduces costs, and keeps your neighbors happy during the build.

Here's everything you need to do before the crew arrives.

1. Clear the Build Area

For Garage Conversions

Empty the garage completely -- everything must go
Arrange temporary storage (pods, storage units, or covered area on your property)
Remove any shelving, workbenches, or wall-mounted items
Clear the area immediately around the garage exterior (3-4 feet minimum)

For New Construction ADUs

Remove patio furniture, play equipment, and landscaping from the build zone
Relocate any outdoor storage sheds that conflict with the ADU footprint
Trim or remove trees within 5 feet of the construction area (check if permits are needed for tree removal)
Remove fencing sections that block construction access

For Junior ADUs

Clear the room or area being converted
Move furniture and belongings out of the conversion zone
Clear hallways and paths that construction crews will use

2. Address Utility Infrastructure

Before construction starts, have your builder verify:

Sewer lateral condition: A video inspection of your sewer line can reveal problems that would delay construction
Water meter capacity: Ensure your water service can support an additional unit
Electrical panel capacity: An older 100-amp panel may need upgrading to 200-amp
Gas meter: Verify the gas meter can support additional appliances

Your builder should handle these assessments, but knowing the potential issues helps you prepare financially. Utility upgrades can add to your total project cost.

3. Secure Construction Access

The construction crew needs access to your property with:

Vehicle access: A clear path for delivery trucks, concrete trucks, and equipment
Material staging area: A flat area to store lumber, drywall, and materials
Power supply: Temporary power connection for tools (your builder typically arranges this)
Water access: A working outdoor spigot for mixing materials and cleanup

If access is through a narrow side yard, discuss logistics with your builder early. Difficult access can affect cost and timeline.

4. Protect Your Existing Property

Construction generates dust, vibration, and foot traffic. Protect your property:

Landscaping: Cover plants near the build zone or temporarily relocate potted plants
Driveway: Discuss protection for your driveway from heavy equipment
Fencing: Expect temporary fencing or barriers around the construction area
Pool/spa: Cover your pool if it's near the build zone
Pets: Plan for pet safety during construction hours -- open gates, loud noises, and unfamiliar workers can be stressful for animals

5. Communicate with Neighbors

Good neighbor relations make construction go smoother:

Notify neighbors about the project, expected timeline, and working hours
Share your builder's contact information so neighbors can reach someone directly with concerns
Address parking: Construction vehicles may temporarily affect street parking
Set expectations: Standard construction hours in most cities are 7:00 AM to 6:00 PM, Monday through Saturday

Cities like Pasadena and Beverly Hills may have stricter noise ordinances -- your builder should know the local rules.

6. Plan for Living During Construction

Garage Conversions

You'll lose your garage for parking -- plan alternative parking
Construction noise is mostly outside your living space
Disruption is relatively minor compared to other ADU types

New Construction ADUs

Backyard access will be limited during construction
Foundation and framing phases are the noisiest
Plan to keep kids and pets out of the backyard during work hours

Junior ADUs

Part of your home will be a construction zone
Discuss dust barriers and containment with your builder
You may want to temporarily relocate if the conversion is extensive

7. Review Your Insurance

Contact your homeowner's insurance provider:

Notify them about the construction project
Verify coverage for construction-related incidents
Ask about builder's risk insurance (your contractor should carry this)
Plan to update your policy once the ADU is complete (adding the ADU increases your insurable property)

8. Set Up Your Financial Plan

Have your financing arranged before construction starts:

Construction draws: Understand your builder's payment schedule
Contingency fund: Set aside 10-15% for unexpected expenses
Timeline buffer: Have living expense coverage if the project takes longer than expected
