Room Additions in Hidden Hills
Hidden Hills homeowners who need more space face a straightforward choice: move or build out what you already own. Top Tech Builders makes the second option faster and less stressful. We handle design, engineering, HOA architectural review submissions, permitting and construction under one roof, so nothing falls through the cracks between separate contractors. Whether you are adding a ground-floor suite, bumping out a kitchen, or going vertical with a second story, our in-house team works through the HOA approval process that governs elevations, materials and roof lines in Hidden Hills before a single shovel goes in the ground.
Design-build remodeling and new construction across Southern California since 2019, delivered end to end by one in-house team, is not a tagline. It is how we are structured and how we protect your schedule.
Hidden Hills sits in the Conejo Valley corridor and is made up of single-family properties on larger lots, many of which have room to grow either outward or upward. The community operates under HOA architectural review, which means addition plans must conform to approved elevations, rooflines and exterior materials before the city permit process can move forward. That two-step approval sequence catches homeowners off guard when they hire a designer and a general contractor separately. Top Tech Builders brings both disciplines in-house, so your plans are drawn to HOA standards from the first draft and revised quickly if the review board requests changes. Buyers in Hidden Hills are typically in the planning stage, researching the right team before committing, which is exactly the right time to talk to us. We have been operating in Southern California since 2019 and work under California Contractors License 1056740.
HOA review can add weeks and can veto material choices the city would have approved.
What that involves
- Ground-floor room additions sized and designed to match your existing footprint and HOA-approved exterior standards
- Second-story additions with structural engineering coordinated in-house from concept through permit
- Bump-outs and kitchen or bathroom expansions that maximize usable space without a full addition footprint
- HOA architectural review package preparation, submission and follow-up handled by our design team
- Full-service design-build delivery: one contract, one point of contact, one in-house crew from drawings to final inspection
Building in a high fire-hazard area in Hidden Hills
This area sits in an elevated fire-hazard severity zone, which changes what the code requires. Chapter 7A applies: ignition-resistant exterior assemblies, ember-resistant attic and foundation vents, tempered or multi-pane glazing, and Class A roof assemblies. Defensible-space clearance around the structure is enforced separately. We build to that standard as a matter of course here, it is not an upgrade, it is the permit condition.

Room Additions questions from Hidden Hills
- How does the HOA architectural review affect my addition timeline in Hidden Hills?
- Hidden Hills requires HOA architectural review before the city permit process begins. Review boards examine elevations, exterior materials and rooflines. Because we draw plans in-house, we can prepare a submittal package that meets those standards from the start and respond to any board comments quickly, rather than cycling back through a separate designer.
- What types of room additions do you build in Hidden Hills?
- We build ground-floor additions, second-story additions and bump-outs. The right option depends on your lot coverage, HOA guidelines and how you want to use the new space. We walk through all three options with you during the planning phase so you make an informed decision before any design work begins.
- Do you handle permits, or is that the homeowner's responsibility?
- We handle permit preparation and submittal as part of our design-build process. Because our design and construction teams work together, the permit drawings are built to what our crew will actually construct, which reduces back-and-forth with the building department.
- How long has Top Tech Builders been doing additions in Southern California?
- Top Tech Builders was founded in 2019 and has been delivering design-build remodeling and new construction across Southern California for seven years under California Contractors License 1056740. That track record matters because additions are complex projects where experience with local approval processes directly affects your outcome.
- What is the advantage of a design-build firm over hiring a designer and a contractor separately?
- When design and construction are separate, gaps between what was drawn and what can be built often surface mid-project and add cost and time. With a design-build firm, one in-house team owns both sides, so conflicts are caught in the design phase and the HOA and permit submittals reflect exactly how the project will be built.
