Two Approvals Before Anyone Picks Up a Tool

Most work that needs a city building permit in Hidden Hills also needs Architectural Approval. Starting construction without prior Architectural Committee approval, or building something different from what was approved, will likely result in a Stop Work Notice and a Board hearing. That is where homeowners here get into trouble, so we work the sequence in the right order and a deck rebuild does not get stopped halfway.

The city sits in the southern Simi Hills near the Santa Monica Mountains on the western edge of the San Fernando Valley, close to the Ventura County line. It has 635 housing units, 593 of them occupied, and just over 90 percent of those are owner occupied. Large single family properties, so long spans, elevated terraces, and surfaces that are part of how the house looks.

Hillside lots put the drainage question first. A terrace that sheds over its edge onto the slope below is contributing to a problem rather than solving one. We settle where the water is collected and discharged, then build the waterproofing to serve that plan.

Long spans also move. A terrace of any real length expands and contracts daily, and that movement concentrates at the joint at the house, the railing penetrations and the edge. Detailing those for movement, rather than sealing them and hoping, is the difference between a surface that lasts and one that opens up in its third summer.

Appearance carries weight on these properties. Finish, color, texture and how the edge is trimmed get decided before the first day.

Pulling a Permit in Hidden Hills

Hidden Hills contracts its building function out. Transtech, under contract with the city, provides Building and Safety, Planning, City Engineering and Public Works, and Environmental Services, so plan check and inspection run through Transtech on the city's behalf. The Architectural Committee approval sits alongside it, and we assemble both packages rather than pulling the permit and finding the committee has not signed off.

Waterproofing Problems We Solve in Hidden Hills

  • Long elevated terraces where daily movement has opened joints and terminations
  • Hillside decks shedding water onto the slope instead of into collected drainage
  • Extended stair runs with wet landings and connections back into the house
  • Railing and post penetrations through the waterproofing on large spans
  • Deck-to-house joints where flashing was never carried behind the wall finish
  • Finish and color decisions that have to satisfy Architectural Committee review

Waterproofing in Hidden Hills: Your Questions

Do I need HOA approval as well as a city permit?

Almost always. Most work that needs a City Building Permit also needs Architectural Approval, and starting without it, or building something different from the approved plans, will likely draw a Stop Work Notice and a Board hearing.

Who actually does the plan check?

Transtech, under contract with the city, provides Building and Safety, Planning, City Engineering and Public Works, and Environmental Services for Hidden Hills. Plan check and inspection run through them on the city's behalf.

Why is drainage the first design decision here?

The city is hillside ground in the southern Simi Hills. Water shed off a terrace edge soaks into the slope below. We decide where it collects and discharges first, then waterproof to serve that.
