Local Knowledge

Remodeling the Conejo Valley's favorite neighborhoods.

Much of Thousand Oaks was built in the 1960s through 1980s, and those homes are now prime remodel territory: original kitchens ready for open layouts, single pane windows begging for replacement, and additions that let families stay in neighborhoods they love. We design and build these transformations daily, keeping the character that makes the Conejo Valley feel like home.

Two things shape almost every Thousand Oaks remodel we price. The first is the original floor plan: 1970s Conejo Valley houses were built with a formal living room nobody uses and a kitchen walled off from everything, and opening that up usually means dealing with a bearing wall and the ductwork above it. The second is the trees. Oaks near the work area affect access, foundation design and sometimes the footprint itself, and they are far cheaper to design around than to resolve after the fact.

Building Here

Building in the City of Thousand Oaks.

Thousand Oaks is home to about 126,000 people and more than 15,000 acres of protected open space, with the oak trees that named the city protected by ordinance. That means tree permits matter here, along with standard building permits through the city's Community Development Department. We plan projects around both from day one. For city services and permit information, visit the City of Thousand Oaks official website.

The oak ordinance is the local rule most likely to surprise a homeowner. Protection extends into the root zone around a tree rather than stopping at the trunk, so grading, trenching and new foundations for an addition or a pool can all trigger review, and it applies to healthy trees on private property. We survey what is on the lot before design gets far, because a plan that ignores a protected oak is a plan that gets redrawn.

Permits & Plan Check

Permits and plan check in Thousand Oaks.

Thousand Oaks runs permitting through its TO/24 portal, and from 1 September 2025 the Building Division accepts digital plans only. Electronic submittals upload under the specific permit type, so picking the wrong category sends a package back before anyone looks at the drawings.

The Building Division counter keeps staggered hours, Monday 7:30am–3pm, Tuesday and Thursday 7:30am–5pm, Wednesday 9:30am–5pm, and alternating Fridays, which matters if a project needs an in-person conversation rather than a portal upload.

FAQ

Thousand Oaks FAQ.

Does Thousand Oaks still accept paper plans?

No. Since 1 September 2025 the Building Division accepts digital plans only, submitted through the TO/24 portal.

Why was my Thousand Oaks submittal returned before anyone reviewed it?

Often the permit type. Electronic submittals upload under a specific permit category, and picking the wrong one sends a package back before anyone looks at the drawings.

When is the Thousand Oaks Building Division counter open?

Hours are staggered: Monday 7:30am to 3pm, Tuesday and Thursday 7:30am to 5pm, Wednesday 9:30am to 5pm, and alternating Fridays. Worth checking if your project needs an in-person conversation rather than a portal upload.

Who do I call about a Thousand Oaks permit?

Thousand Oaks Building Division on (805) 449-2320, or building@toaks.gov.

Do I need approval to work near an oak tree in Thousand Oaks?

Very likely. The city protects its oaks by ordinance, and that protection reaches into the root zone around the tree, not just the trunk. Grading, trenching and new foundations nearby can all pull a project into review. We identify affected trees during design so the permit path is known before drawings are finished.

How long does a kitchen remodel take in Thousand Oaks?

Plan on the build running roughly six to ten weeks once demolition starts, with permits and cabinet lead times ahead of that. The long pole is almost never the construction, it is approvals and millwork. We order long-lead items before demolition so the house is not sitting open waiting on a delivery.

Can you handle the city permit and my HOA approval together?

Yes, and they are genuinely separate processes with separate timelines. Many Conejo Valley communities require architectural committee approval that has nothing to do with the city. We prepare both packages together so you are not waiting for one to finish before the other begins.
