Burbank Remodeling Contractor remodels hillside homes in Burbank, California, in the neighborhoods climbing the Verdugo slopes above Glenoaks and out toward La Tuna Canyon. Building on a hillside is a different discipline from building on flat ground, and pretending otherwise is how projects end up doubling in price at plan check.
Properties in Burbank's hillside area are subject to a hillside development permit, which brings soils and geology reports, grading and drainage review, and a longer approval path. It also brings genuine engineering: caissons, grade beams, retaining walls and access problems that decide how material even gets to the site. Call (747) 330-0305 and we will scope it honestly.
The Burbank Hillside Development Permit and What It Triggers
Burbank applies a separate review process to construction in its hillside area, layered on top of the ordinary building permit. In practice, that means a supplemental application, closer scrutiny of grading, drainage and building height as measured on a slope, and frequently a requirement for a soils report and a geology report prepared by licensed professionals.
The time cost is real. A hillside addition that would take ten weeks of plan check in the flats can take six months. We build that into the schedule from the start rather than promising a flat-lot timeline and explaining later.
Foundations and Structure on a Slope
Caissons and Grade Beams
Where the slope is steep or the soil is not competent near the surface, the structure gets carried on drilled piers taken down to bearing, tied together with grade beams. It is the most common foundation solution on the steeper Burbank hillside lots and it is a substantial share of the budget.
Retaining Walls
Engineered walls holding back cut slopes, with drainage behind them and a footing sized for the load. A failed or undersized retaining wall on a hillside lot is not a cosmetic problem, and older properties frequently have one that was never engineered.
Tall Cripple Walls and Seismic Bracing
Downhill-facing houses often sit on tall cripple walls that were never braced. Bracing them and bolting the house to its foundation is standard scope on any hillside remodel we do, because the alternative is leaving a known weakness in place while spending money on finishes.
Cantilevers and Decks
View-side living space and decks projecting over the slope. These need engineering for uplift and lateral loads, and the connections back into the house are where failures show up years later.
Drainage, Fire Zones and Site Access on Burbank Hillside Lots
Water is the thing that quietly destroys hillside properties. Runoff has to be collected and taken to an approved point of discharge rather than allowed to sheet across a slope or saturate the soil behind a wall. Any remodel that changes roof area or hardscape changes the drainage calculation, and the city looks at it.
The upper hillside areas also sit in or near very high fire hazard severity zones, which brings ignition-resistant construction requirements: ember-resistant vents, rated eaves and soffits, appropriate decking material and defensible space. And then there is simple access. If a concrete truck cannot reach the pad, the concrete gets pumped, and if a pump cannot reach it, the cost changes again.
On a hillside lot, ask about access before you ask about finishes. How material reaches the site can move a budget more than a cabinet grade ever will.
What Hillside Work Costs Above the Burbank Flats
Expect a meaningful premium over the same project on flat ground. Caisson foundations, retaining, engineered drainage, longer permitting and difficult access commonly add 20 to 40 percent to a comparable flat-lot scope, and steep sites with poor access can go beyond that.
The upside is that hillside properties are worth what they are worth because of the views and the setting, and well-executed work on them holds its value. The projects that go badly are the ones bid by someone who priced it like a flat lot and started discovering the slope in month two.

How do I know if my property is in the Burbank hillside area?
It is a mapped designation rather than a judgment about how steep your driveway feels, and the city can confirm it against your address. We check it as the first step on any project above the flats, because it determines the entire permitting path and a large part of the budget.
Do I need a soils report?
On hillside projects involving foundations, grading or additions, usually yes, and often a geology report alongside it. They are prepared by licensed geotechnical and engineering geology professionals, they take several weeks, and their findings drive the foundation design. Budget for them at the start rather than treating them as a plan check surprise.
Can I add a second story to a hillside house?
Sometimes, and height on a slope is measured in a way that is less generous than on flat ground. The existing foundation also has to carry the load, which on a hillside frequently means new caissons. It is worth a feasibility review before design, since the answer genuinely varies lot to lot.
Why does hillside work take so much longer to permit?
Because more departments look at it and more consultants have to produce documents first. Soils and geology reports take weeks to prepare and then get reviewed. Grading and drainage plans get their own review. Building height and setbacks on a slope are calculated in a way that invites correction cycles. Six months of pre-construction on a hillside addition is normal rather than alarming.
