What should you do in the first 30 days?

A short checklist prevents the common new-owner oversights. Brian Cooper serves the Santa Clarita Valley from our Simi Valley headquarters.

  1. Transfer utilities. Electric, gas, water, trash, and internet in your name.
  2. Change the locks. And set up or update any security system.
  3. Store closing documents. Keep your deed, statement, and disclosures safe.
  4. Update your address. Postal service, banks, employer, and subscriptions.
  5. Set up HOA accounts. If your community has an HOA.
  6. Confirm insurance and taxes. Verify coverage is active and understand your tax setup.
  7. Start a maintenance routine. Filters, smoke detectors, and seasonal tasks.

Expect a supplemental property tax bill

After a change of ownership, the Los Angeles County Assessor reassesses the property, which often generates a supplemental property tax bill separate from your regular bill. Budget for it so it is not a surprise. Confirm details and timing with the Los Angeles County Assessor. This is general information, not tax advice.

Security and safety first

Changing the locks is a simple priority — you do not know who has copies of the old keys. Test smoke and carbon-monoxide detectors, locate the main water shutoff and electrical panel, and note the gas shutoff. Knowing these basics matters, especially in the SCV where wildfire awareness is part of life.

HOA and community setup

If your home is in an HOA or master-planned community, set up your account, review the rules, and learn the dues schedule. Communities in SCV master-planned communities often have amenities and guidelines worth understanding early.

Start a maintenance rhythm

Replace HVAC filters, service the system before peak summer, clear gutters, and address any deferred items from your inspection. A little routine maintenance protects your investment and prevents bigger expenses later.

  • Replace HVAC filters and service the system
