Building and Remodeling in La Crescenta-Montrose
When a Crescenta Valley household is ready for an ADU, a room addition, a second story or a new custom home, Simply Construction can take it on as a licensed general contractor in La Crescenta-Montrose. The first thing we check on any project here is which government issues the permit, because most of the community is unincorporated Los Angeles County while some streets fall inside the City of Glendale.
From there we manage the whole job under one contract: feasibility, engineering, the county or city submittal, construction and final inspection. The Crescenta Valley's slopes, rocky soil and foothill fire exposure all show up in the budget and schedule, so we raise them at the first site visit rather than in the middle of construction, when changes cost the most.
Local Knowledge
Building in La Crescenta-Montrose: Foothill Lots and Two Permit Paths
La Crescenta-Montrose sits in the Crescenta Valley between the San Gabriel Mountains and the Verdugo Mountains, and most streets climb steadily north toward the Angeles National Forest. The ground is an alluvial fan built from material washed out of the canyons above. That is why so many front yards are edged with walls of rounded local stone, and why digging for footings or a pool can turn up boulders big enough to need a machine.
The same geography explains the flood control works that line the foothills. Debris flows out of the canyons have a long history here, and the county maintains debris basins and channels to catch them. Upper streets near the forest edge also face wildfire exposure, and parcels there may fall within mapped fire hazard severity zones with stricter construction and brush clearance rules.
Permits follow the parcel. Unincorporated addresses go through LA County Public Works Building and Safety for plan check and inspection, with LA County Regional Planning handling zoning, while addresses inside Glendale go through the City of Glendale. Each agency applies its own ADU ordinance on top of state law, so we confirm jurisdiction from the parcel record before any design work starts.
Services
Construction & Remodeling Services in La Crescenta-Montrose
From ground-up homes to kitchens, here is how each of our services applies to La Crescenta-Montrose properties.
Custom Home Building in La Crescenta-Montrose
A custom home on one of the upper, sloping streets of La Crescenta-Montrose has to work with grade changes from the curb to the back fence. That brings in a soils report, retaining walls, drainage designed for runoff from the slope above, and a foundation plan that can cope with buried boulders. If the lot falls within a fire hazard severity zone, the house also needs ember-resistant vents, ignition-resistant siding and a Class A roof. We price these site conditions before the design is final so excavation doesn't open with a change order.
ADU Construction in La Crescenta-Montrose
For an unincorporated La Crescenta-Montrose parcel, LA County reviews a backyard ADU under its own ordinance; a Glendale parcel follows Glendale's. Either way, state law guarantees room for at least an 800 square foot ADU with 4-foot side and rear setbacks, and a detached unit can generally reach 1,200 square feet. On a sloped backyard, the cost drivers are grading, retaining walls and the utility runs back to the street, so we survey those before a floor plan is drawn and place the unit where construction is practical.
Garage Conversions in La Crescenta-Montrose
Where a La Crescenta-Montrose home has a detached garage behind the house, often at the end of a long driveway that climbs or drops, converting it to an ADU removes the replacement parking requirement under state law. The work usually includes new footings or a slab upgrade, insulation, egress windows and a separate electrical feed. Some older garages were set into the slope with retaining walls on one or more sides, and those walls need an engineer's review and waterproofing before the space can become a bedroom.
Room Additions in La Crescenta-Montrose
Room additions in La Crescenta-Montrose often extend toward a backyard where the grade rises or falls by several feet. That decides whether the addition sits on a raised floor, a stepped foundation or a slab, and how its roof ties into the old one. Unincorporated lots are reviewed against LA County zoning standards for setbacks and height, while Glendale lots follow Glendale's code. We design drainage around the addition with care, since water moving down the valley from the slopes above is a constant consideration here.
Second-Story Additions in La Crescenta-Montrose
A second story can make sense on the flatter streets closer to the valley floor, where yard space is limited and building up preserves what's left of the garden. The engineering questions are familiar: whether existing footings can carry the new load, where new shear walls go, and how a stair fits without losing a bedroom. On the upper slopes, mountain views and neighbors' privacy become part of the design conversation. We coordinate the structural design with the county or Glendale plan check so the framing crew isn't waiting on revisions.
Garage Construction in La Crescenta-Montrose
A new garage in La Crescenta-Montrose can involve a steep driveway, so we plan the slab elevation, the approach slope and the drainage together. A detached garage can be built with the foundation, ceiling height and utility stubs a future ADU would need. On lots near the forest edge, we specify ignition-resistant materials for the garage as well as the house. Excavation here may hit large rocks, which we account for in the site work plan rather than leaving it to a change order later.
Whole-House Remodeling in La Crescenta-Montrose
When a La Crescenta-Montrose house has been expanded in stages over the years, the first job in a whole-house remodel is sorting out what was permitted and what was not. From there we open up the plan, replace aging electrical and plumbing, add foundation bolting and bracing, and correct drainage around the foundation. The 2025 Energy Code applies to permit applications submitted on or after January 1, 2026, which shapes insulation, window and mechanical choices in a full remodel.
Kitchen Remodeling in La Crescenta-Montrose
Kitchen remodels in La Crescenta-Montrose often aim to open the room to a back patio or a view of the mountains. That usually means a new beam where a bearing wall comes out, a larger electrical service, and new circuits for induction or gas appliances. For unincorporated homes, LA County issues the permit, and Glendale issues it for homes inside the city. We sequence the work so the rest of the house stays livable while the kitchen is under construction.
Bathroom Remodeling in La Crescenta-Montrose
Bathroom remodels in the Crescenta Valley's older houses can reveal galvanized pipe, undersized drains or subfloors softened by years of slow leaks. We repair what's behind the tile before choosing finishes, then install waterproofing, a ducted exhaust fan and showers sloped properly to the drain. When a new bath is part of a primary suite, we map the plumbing route early, because some houses here sit on raised foundations with tight crawlspaces and others sit on slabs.
Fire Rebuilds in La Crescenta-Montrose
La Crescenta-Montrose backs onto the Angeles National Forest, and homes on the upper streets live with wildfire exposure. A rebuild after a fire must meet California's wildfire construction standards where the parcel is in a fire hazard severity zone, and hillside lots may need fresh soils and drainage reports before plans are approved. We work with your insurer, the engineers and the county or Glendale plan checker to move from a cleared lot to a permit set, and we design the new house with defensible space in mind.
Junior ADUs (JADU) in La Crescenta-Montrose
A junior ADU adds a second unit in La Crescenta-Montrose without grading a sloped backyard at all. The rules are simple: the space sits inside the existing house or an attached garage, stays at or under 500 square feet, includes at least an efficiency kitchen, and stays tied to an owner who lives on the property. For a family that wants a relative close by, turning a bedroom wing or an attached garage into a suite is usually faster and simpler than building a detached ADU on a slope.
SB 9 Lot Splits & Duplexes in La Crescenta-Montrose
SB 9 reaches qualifying single-family lots in both unincorporated La Crescenta-Montrose and the Glendale portion, but the foothill setting screens out some parcels. Sites in very high fire hazard severity zones are excluded unless the project adopts the required fire mitigation measures, and steep lots can make two units hard to fit. For a lot split, each new parcel must be at least 1,200 square feet and 40 percent of the original lot, and the owner signs an affidavit to live in one unit for at least 3 years.
Patios, Decks & Outdoor Living in La Crescenta-Montrose
Outdoor living in La Crescenta-Montrose tends to follow the slope: terraced patios, retaining walls faced in local stone, and decks that take in the San Gabriels or the Verdugos. Near the forest edge, decks should use fire-resistant framing and decking, and combustible structures should be kept away from the house where fire rules call for it. Drainage behind every retaining wall and under every patio gets the same attention as the structure, because runoff moving down the valley does not stop at property lines.
Why Choose Us
Why La Crescenta-Montrose 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.
One Team From Plans to Final Inspection
Design, engineering, permitting and construction sit under one contract and one project lead, so nobody points fingers between the designer, the engineer and the builder when a detail changes. You get one schedule, one point of contact and regular progress updates from the first site visit through the final inspection and sign-off on your La Crescenta-Montrose project.
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 La Crescenta-Montrose: Common Questions
Do I get my permit from LA County or Glendale in La Crescenta-Montrose?
It depends on the parcel. Most of La Crescenta-Montrose is unincorporated, so permits go through LA County Public Works Building and Safety, with LA County Regional Planning handling zoning. Some streets in both Montrose and La Crescenta are inside the City of Glendale and follow Glendale's rules and ADU ordinance. We confirm jurisdiction from the parcel record before design starts.
Why can foundations cost more on some Crescenta Valley lots?
The valley floor is an alluvial fan built from material washed out of the San Gabriel canyons, and excavation can hit large rocks and boulders. Sloped lots may also need stepped footings, retaining walls or deeper foundations, depending on what the soils report finds. We bring in geotechnical input early so the foundation design and the price reflect what is actually in the ground.
Can I build an ADU on a sloped lot?
In most cases, yes. State law protects at least an 800 square foot ADU with 4-foot side and rear setbacks, whether the parcel is in the county or in Glendale. A sloped site adds grading, retaining walls and longer utility runs, and it can affect where the entrance and path go. We study the site first so the unit lands where it can be built efficiently.
