Adding on in Hidden Hills? Map the approval path before you pay for design.

Get the free Hidden Hills Home Addition Approval & Feasibility Checklist. A one-page guide to the two-gate path, the lot and fire-zone questions to settle early, and the documents to gather before your first meeting.

Hi, I am Lior Mazor. I run Hillstar Construction, and I build and remodel estate homes behind the gate in Hidden Hills and across the West Valley.

A Hidden Hills addition is not a standard Los Angeles addition. It passes through two separate approvals that most homeowners find out about in the wrong order: a private architectural review run by the Hidden Hills Community Association, and then a building permit from the City of Hidden Hills, its own incorporated city. Treating them as one is where timelines and budgets quietly slip. I put the parts that actually decide your project onto a single page you can use before you spend a dollar on plans.

What is on it:

• The two-gate sequence in plain order: the HHCA architectural review first, then the City of Hidden Hills permit, and why they are different kinds of approval
• The lot questions to settle early: your buildable envelope, hillside grading and whether a soils or geology report is likely, and your mapped fire hazard zone
• Why not every parcel in the city carries the same fire designation, and how to confirm yours before design
• The documents worth gathering before your first meeting, so you arrive ready instead of guessing
• The questions that tell you whether a builder actually knows this jurisdiction

It is free, it is written for homeowners rather than for a plan checker, and it is short enough to actually use. No prices, no sales pitch.
