Hidden Hills, CA
Building and Remodeling in Hidden Hills
Simply Construction serves as a general contractor in Hidden Hills for owners building custom estates, guest houses, room additions and garages on the city's horse-friendly lots. Hidden Hills is a small incorporated city that is fully gated, with private roads, bridle trails and white rail fences, and its approvals run on two tracks: the City of Hidden Hills and the Hidden Hills Community Association.
We plan every project to clear both. That means reading the association's architectural guidelines before design, arranging gate access for crews and deliveries, and managing city permits, engineering and inspections as a licensed California general contractor.
Local Knowledge
How Hidden Hills Approvals and Lots Shape a Project
Hidden Hills was laid out as a ranch-style equestrian community, and it still looks the part. Streets such as Round Meadow Road, Long Valley Road and Spring Valley Road run past large lots with barns, corrals and arenas, tied together by a bridle trail network that riders use to move through the community without crossing onto busy roads.
The Hidden Hills Community Association maintains the private roads and gates and reviews the design of new homes and exterior changes. Its review is separate from the city's, and plans are expected to respect the ranch character that gives the community its identity. A design that works for the city but ignores the association's guidelines will come back for revisions, so we read those guidelines first.
The valley floor is gentle, and the edges climb into brush-covered hills. The 2018 Woolsey Fire burned through neighboring Bell Canyon, so wildfire-resistant construction and defensible space shape new work here. The city also adopts its own ADU rules in addition to the state's, which matters on any lot where a guest house is planned.

Construction & Remodeling Services in Hidden Hills
From ground-up homes to kitchens, here is how each of our services applies to Hidden Hills properties.
Custom Home Building in Hidden Hills
A custom home in Hidden Hills is designed as much for the association as for the city. We start with the Community Association's architectural guidelines and the lot's existing equestrian features, then work out the siting of the house, barn, arena and guest house together so circulation for cars, horses and trailers still works. The city reviews zoning and building plans, and the association reviews design. We carry both approvals, the engineering and the Title 24 solar requirement through to a finished home that fits the community's ranch character.
ADU Construction in Hidden Hills
On large Hidden Hills lots, a detached guest house is often the natural ADU, and a guest house with its own kitchen is legally an ADU. The city layers local ADU standards over the state's, and state law generally allows a detached unit of up to 1,200 square feet. The Community Association cannot prohibit an ADU, but it can apply reasonable design standards, so we design the unit to match the main house and submit to both reviewers together.
Garage Conversions in Hidden Hills
Converting a garage in Hidden Hills is less about finding space than about repurposing a structure, since many estate lots have room for a new garage elsewhere. A converted garage can become an ADU, a gym or an office, and state law does not require replacement parking when it becomes an ADU. Because garage doors usually face the street or a motor court, the association will want to review the new facade, so windows, doors and materials are designed to match the house.
Room Additions in Hidden Hills
Hidden Hills lots usually have space for a ground-floor addition, and a single-story addition keeps to the ranch-style character the community is known for. We extend primary suites, family rooms and wings with rooflines, siding and trim that match the original house, and we route the design through the Community Association before city plan check. Access for concrete trucks and equipment is planned around the gates and private roads so the neighbors and riders are not disrupted.
Second-Story Additions in Hidden Hills
A second story changes the low, ranch-style profile that Hidden Hills is built around, so the design question comes before the engineering one. We review the Community Association's guidelines and the city's height limits to see what is realistic for the lot. If a second level makes sense, an engineer sizes new footings, shear walls and connections, and we shape the upper floor to sit low within the roofline rather than stack a full box on top of the original house.
Garage Construction in Hidden Hills
New garages in Hidden Hills are often designed alongside barns, tack rooms, workshops or a guest house, and on larger lots they can be detached with a motor court in front. We coordinate structure, drainage, driveway grades and gate logistics, and we design garage doors and materials to match the main house before the Community Association reviews them. On lots near brush, we use ignition-resistant materials and ember-resistant vents throughout the structure.
Whole-House Remodeling in Hidden Hills
A whole-house remodel in Hidden Hills is often the alternative to a tear-down: keeping a sound structure while updating systems, finishes and layout throughout. We rewire, replumb, upgrade heating, cooling and insulation, and rework rooms, and we submit exterior changes such as new windows, siding or rooflines to the Community Association. Interior phases can often proceed on city permits while exterior design is still under association review.
Kitchen Remodeling in Hidden Hills
Hidden Hills kitchens are often the center of a large single-level plan that opens to a patio, a pool or a view of the arena. We handle structural changes, larger gas and electrical service, commercial-style ventilation and custom cabinetry, and we coordinate new exterior doors or windows with the Community Association. Because every delivery comes through the gates, cabinetry, stone and appliance drop-offs are scheduled with care.
Bathroom Remodeling in Hidden Hills
Bathroom remodels in Hidden Hills range from primary suites in the main house to guest house and pool house baths. We waterproof showers and tub surrounds fully, vent every bath outdoors, and choose durable tile and fixtures. A bath or mudroom by the barn or rear entry is a useful addition on equestrian lots, and pool baths benefit from slip-resistant floors and fixtures rated for wet use.
Fire Rebuilds in Hidden Hills
The 2018 Woolsey Fire burned through neighboring Bell Canyon, a reminder of the fire exposure on the brush-covered hills around Hidden Hills. If a home, barn or guest house here is damaged by fire, we handle the rebuild, starting from a cleared site, through city permits and Community Association review, building to California's wildfire construction standards. Barns, hay storage and fencing are planned with fire in mind rather than treated as an afterthought.
Junior ADUs (JADU) in Hidden Hills
A junior ADU in Hidden Hills creates a private suite of up to 500 square feet inside the main house, with its own entrance and at least an efficiency kitchen. It suits a caregiver, live-in staff or a family member. Since it stays within the existing walls, the Community Association's interest is usually limited to any new exterior door, and there is no new building to site among the barns and paddocks.
SB 9 Lot Splits & Duplexes in Hidden Hills
SB 9 applies to single-family zones in every California city, including Hidden Hills, but it does not override the Community Association's CC&Rs, and a parcel mapped as a Very High Fire Hazard Severity Zone qualifies only with the required fire mitigation measures. Each new parcel still has to be at least 40 percent of the original lot and no smaller than 1,200 square feet. In practice, the private deed restrictions here can matter as much as state law, so we review both with you before any design.
Patios, Decks & Outdoor Living in Hidden Hills
Outdoor living in Hidden Hills is organized around the lot: pools, arenas, gardens and long views across open land. We build patio covers, loggias, outdoor kitchens and decks that match the home's ranch-style architecture, using ignition-resistant materials where fire rules apply. Hardscape is graded so water drains away from barns and paddocks as well as the house, and the Community Association reviews exterior structures before we build.
Why Choose Us
Why Hidden Hills Homeowners Choose Simply Construction
Contracts Written the Way California Law Requires
California caps a home improvement down payment at $1,000 or 10 percent of the contract price, whichever is less, and after that a contractor may only bill for work completed or materials delivered. Our contracts follow that structure: a line-item scope, a payment schedule tied to finished milestones, and written change orders before any extra work begins. You always know what you are paying for and why.
Straight Answers on Feasibility
Some lots cannot fit the project an owner has in mind. We check zoning, setbacks, height limits, easements, slope and utility capacity early, and we tell you plainly what is achievable before you spend money on full drawings. When state law opens a path that the local code seems to block, as ADU and SB 9 rules often do, we explain how it applies to your property.
Written, Line-Item Estimates
Before you commit, you receive a written estimate that breaks the project into its real parts: design and engineering, permit and utility fees, foundation, framing, systems, finishes and site work. Allowances are named and priced, so you can see where your selections move the budget. If the scope changes, the numbers change on paper first, never as a surprise on the final invoice.

FAQ
Building in Hidden Hills: Common Questions
Do I need Hidden Hills Community Association approval in addition to a city permit?
In almost every case. The City of Hidden Hills issues building permits and enforces zoning, while the Community Association reviews the design of new homes and exterior changes under its own guidelines. The two reviews are separate, and a project generally needs both before construction starts. We prepare drawings that address both sets of requirements and track each approval to completion.
How do crews and deliveries get through the Hidden Hills gates?
Entry is controlled at the gates, and the Community Association sets rules for contractors, working hours and deliveries on its private roads. We register crews and schedule concrete, lumber and material drop-offs within those rules, and we keep trucks off bridle trails and horse crossings. Settling access before the job starts avoids delays at the gate on pour days.
Can I build a guest house on my lot?
In most cases, yes. State law requires every city, Hidden Hills included, to allow ADUs, and the city has its own ADU ordinance that adds local standards. The association cannot prohibit an ADU but can apply reasonable design rules. Setbacks, barn and paddock locations, septic or sewer capacity and fire access all affect where a guest house can go.
