Old Town Tustin
historicNOT an HOA — Old Town is a city-administered historic preservation district. Design review is through the City of Tustin, not a private association, but exterior change requirements are strict.
Contractor's Take
“Old Town Tustin is the trickiest part of this city because many homeowners don't realize they're in a historic district until the city rejects their plans. The rules around windows, siding, and roofing materials are strict — we always tell Old Town homeowners to hire an architect who has worked in Old Town specifically, not just in Tustin generally. The other big gotcha is North Tustin, which is NOT part of the City of Tustin and permits through the county.”

Frequently Asked Questions
Is Old Town Tustin an HOA?
No. Old Town Tustin is a city-administered historic preservation district, not a private HOA. Design review is handled by the City of Tustin Community Development Department. The requirements are in some ways stricter than HOA review because they are codified in city ordinance.
Do I permit in Tustin or in Orange County?
If your address is in the incorporated City of Tustin, you permit with the city. If you're in North Tustin, Lemon Heights, or Cowan Heights (all unincorporated Orange County), you permit through OC Public Works. Check your property tax bill or OC Parcel Viewer to confirm.
Can I replace windows in Old Town Tustin?
Yes, but the replacement windows must match the historical character of the home — typically wood or wood-clad frames with period-appropriate profiles. Vinyl and modern aluminum windows are generally not approved. Budget more for window replacement in Old Town than elsewhere.
