Sherwood Forest is zoned RA, with a 17,500-square-foot minimum lot, and the 1950s Devonshire Highlands and Devonshire Country Estates tracts have lots of up to half an acre. Add mature walnut and sycamore canopy and there is room for a full outdoor program without crowding the house. The trade is heavier tree protection review and, on housing repaired after 1994, foundations and framing connections that deserve a careful look before we tie anything new into them. Lots range from standard postwar tract lots to large ranch parcels: up to about half an acre in Devonshire Highlands and Devonshire Country Estates, and at least 17,500 square feet in RA-zoned Sherwood Forest. Many have circular drives, mature landscaping and room for a detached structure well behind the main house. We are a design-build team, which means the people who draw your project are the people who build it. Design, engineering, permits and construction run through one project manager and our own crews, so nothing gets lost in a handoff between a salesperson and a subcontractor. We are licensed, bonded and insured, [CSLB license #1119054](https://www.cslb.ca.gov/OnlineServices/CheckLicenseII/LicenseDetail.aspx?LicNum=1119054) . Permits in Northridge: LADBS handles residential building, grading and pool permits, with plan check and inspection routed through the Van Nuys Development Services Center. Land use is guided by the Northridge Community Plan. A limited portion of Northridge is on the City's Designated Hillside Areas map, generally between White Oak Avenue and Bull Creek and between Devonshire and Nordhoff Streets, and parcels there fall under the Baseline Hillside Ordinance (No. 184,802), which limits grading, floor area and height. Mature oak, western sycamore and Southern California black walnut are common on the larger estate lots and are protected at four cumulative inches of trunk diameter under Ordinance 186,873, so an arborist report is frequently part of the submittal. ZIMAS shows whether a parcel sits in a CGS-mapped liquefaction zone; even there, LADBS Information Bulletin P/BC 2026-044 exempts one- and two-family dwellings, ADUs under three stories, and pools, spas and decks from the liquefaction-zone investigation, and plan check confirms whether a soils report is needed. Review length varies with scope. Permit details checked September 2026 against [LADBS](https://dbs.lacity.gov/sites/default/files/efs/forms/pc17/design-and-construction-of-swimming-pools-ib-p-bc2017-014.pdf) and [LA City Planning](https://planning.lacity.gov/odocument/55e38590-0dcd-46ca-9afa-4b11ba9558b0/Northridge_Community_Plan.pdf) . Rules change, so we confirm them again for your parcel. What We Build - Large-lot outdoor living master plans - Arborist coordination for protected trees - Detached ADU and guest house siting - Measured surveys and existing-condition drawings - Permit-ready plan sets for submittal - Structural engineering coordination - Title 24 energy compliance documentation - ADU and addition planning packages - Pool, hardscape and structure permits - Soils and geotechnical report coordination - HOA architectural review submissions - City submittal and plan-check correction responses - Inspection scheduling and sign-off Local Conditions #### What to Know in Northridge These local conditions change the scope, the schedule and the budget. 01 Estate lots carry mature walnut, oak and sycamore canopy whose root zones dictate where a pool shell, footing or utility trench can physically go. 02 Alluvial fan soils vary over short distances, and expansive clay lenses appear often enough that a soils report is worth pulling before a shell or slab is priced. 03 Much of the housing stock was repaired after the 1994 earthquake, so foundations, chimneys and framing connections deserve verification before a large addition or second story is tied in. 04 Deep parcels mean long electrical, gas and plumbing runs to a rear pool or detached unit, which affects trenching cost, pump sizing and gas line diameter.

[Get a line-item price for your Northridge property](https://www.remodelyourvibe.com/contact-us) The Process #### How We Work in Northridge 01 ##### Feasibility We check zoning, setbacks, easements and utilities to confirm what the property will actually support before you spend on drawings. 02 ##### Survey & As-Builts The site and existing structure are measured and drawn so the permit set starts from reality, not an old plot plan. 03 ##### Design Development Plans and elevations developed to the level of detail plan check expects, with 3D so you can see it clearly. 04 ##### Consultants Structural engineering, Title 24 and, where the site needs it, a soils report are coordinated into one set. 05 ##### Submittal We make the submittal and act as the applicant, so correspondence with the city comes to us rather than to you. 06 ##### Corrections & Issue We respond to plan-check corrections, resubmit, and see the permit through to issue. Questions #### What Northridge Homeowners Ask Who issues the permits for this work in Northridge? Los Angeles Department of Building and Safety (LADBS). LADBS handles residential building, grading and pool permits, with plan check and inspection routed through the Van Nuys Development Services Center. Land use is guided by the Northridge Community Plan. A limited portion of Northridge is on the City's Designated Hillside Areas map, generally between White Oak Avenue and Bull Creek and between Devonshire and Nordhoff Streets, and parcels there fall under the Baseline Hillside Ordinance (No. 184,802), which limits grading, floor area and height. Mature oak, western sycamore and Southern California black walnut are common on the larger estate lots and are protected at four cumulative inches of trunk diameter under Ordinance 186,873, so an arborist report is frequently part of the submittal. ZIMAS shows whether a parcel sits in a CGS-mapped liquefaction zone; even there, LADBS Information Bulletin P/BC 2026-044 exempts one- and two-family dwellings, ADUs under three stories, and pools, spas and decks from the liquefaction-zone investigation, and plan check confirms whether a soils report is needed. Review length varies with scope. We prepare the drawings, make the submittal and handle plan-check corrections ourselves, so you are not the one chasing plan check. What makes building in Northridge different? Lots range from standard postwar tract lots to large ranch parcels: up to about half an acre in Devonshire Highlands and Devonshire Country Estates, and at least 17,500 square feet in RA-zoned Sherwood Forest. Many have circular drives, mature landscaping and room for a detached structure well behind the main house. One local condition that shapes the work: Estate lots carry mature walnut, oak and sycamore canopy whose root zones dictate where a pool shell, footing or utility trench can physically go. Which parts of Northridge do you work in? All of it, including Sherwood Forest, Devonshire Highlands and Devonshire Country Estates. Our crews run every job out of our Cahuenga Pass base in Los Angeles, with our own people on site. What do plans and permits cost in Northridge? Plans, drawings and permit management: generally $4,500 to $25,000+ across Southern California. What moves it is project type and size, whether structural engineering, Title 24 or a soils report is required, and how many jurisdictions or review bodies are involved. We give line-item pricing after seeing the site rather than quoting a number over the phone. Can you do the plans without doing the build? Yes. Plans and permits is a service we sell on its own, and plenty of clients use us for the drawing set and permit management and build with someone else. We would rather do it properly than tie it to a construction contract. Why do permit costs vary so much? Because the required consultants vary. A straightforward patio cover needs a modest set. An ADU on a sloped lot may need structural engineering, Title 24, a soils report and a survey, and each of those is a separate specialist fee on top of the city's own plan-check and permit charges. What causes plan-check corrections? Most commonly incomplete structural detail, missing Title 24 forms, drainage not shown, or a discrepancy between the site plan and the survey. Corrections are normal, not a failure. The thing that costs time is a slow response to them, which is why we act as the applicant. Do you handle HOA approval too? Yes, where a community requires it. HOA architectural review runs on its own calendar and its own standards, entirely separately from the city, and starting it late is one of the most common reasons a project slips. #### More Services in Northridge [Pool & Spa Remodeling in Northridge](https://www.remodelyourvibe.com/services/swimming-pool-spa/northridge) [Backyard & Outdoor Living in Northridge](https://www.remodelyourvibe.com/services/exterior-remodeling/northridge) [ADUs & Additions in Northridge](https://www.remodelyourvibe.com/services/adus-additions/northridge) [Kitchen, Bath & Interior Remodeling in Northridge](https://www.remodelyourvibe.com/services/interior-remodeling/northridge) [Everything we build in Northridge](https://www.remodelyourvibe.com/service-areas/northridge) #### Plans, Permits & Design Nearby [Plans, Permits & Design in Granada Hills](https://www.remodelyourvibe.com/services/plans-permits/granada-hills) [Plans, Permits & Design in Porter Ranch](https://www.remodelyourvibe.com/services/plans-permits/porter-ranch) Planning Guides #### Before You Build in Northridge Costs, materials and process notes from our own projects.
