Remodeling a Home in Northridge

Permit History

Nineteen Ninety-Four Still Shapes Northridge Houses

The 1994 earthquake was centred here, and a very large number of houses in the area were damaged, repaired, strengthened or partly rebuilt in the years that followed. Three decades on, that history is still the most important unknown in a Northridge remodel.

Some of that work was done under permit, engineered and inspected. Some was not.

You are not only remodeling a house. You are inheriting whatever was done to it.

This is not an accusation against anyone. It is a practical reality of an area that repaired tens of thousands of buildings quickly. It matters because unpermitted structural work discovered during plan check becomes your problem, mid-project, at your cost.

Ask before you commit: has anyone pulled the permit history for this address, and does the plan depend on any structure whose origin is unknown?

The Housing Stock

Post-War Ranch Houses on Slabs, on Generous Lots

Much of Northridge was built out in the post-war decades: single-storey ranch houses, frequently on a concrete slab-on-grade, on lots that are noticeably larger and flatter than in most of the Valley.

The slab drives the same decision it does everywhere it appears:

Jurisdiction

Permits Are Handled by the City of Los Angeles

Northridge is inside the City of Los Angeles, so the Los Angeles Department of Building and Safety handles plan check, permits and inspections. There is no separate Northridge building department.

Where structural work is involved — and in Northridge it often is — expect engineering to form part of the submittal. If the project touches or reveals earlier structural work, plan check is where that surfaces.

Most of Northridge sits on flat ground away from the fire hazard severity zones that affect the hillside communities. Properties toward the northern foothills should still be confirmed individually.

Ask before you commit: is structural engineering included in this price, and what happens to the schedule and the cost if plan check raises a question about existing work?

Accessory Dwelling Units

Northridge Lots Suit ADUs Better Than Most

California law makes accessory dwelling units broadly permitted and Los Angeles applies that through its own ordinance. Northridge is one of the more straightforward parts of the Valley in which to build one, because the lots tend to be larger, flatter and more regular.

7 Questions That Separate Two Estimates

1. Has anyone pulled the permit history for this address?
2. Does the plan rely on any existing structure whose origin is unknown?
3. Is this priced on a slab or a raised foundation?
4. Is structural engineering included, and who pays if plan check raises a question?
5. What is excluded — not what is included?
6. Who applies for the permit, and whose licence is on it?
7. How are change orders priced and approved once work has started?

Our guide to comparing remodeling estimates covers how to read two proposals that appear to describe the same project but do not.

Questions About Remodeling in Northridge

Why does the 1994 earthquake still matter?

It was centred here, and an enormous number of local houses were damaged, repaired, strengthened or partly rebuilt afterwards. Some of that work was permitted, engineered and inspected; some was not. Unpermitted structural work discovered during plan check becomes the current owner’s problem, mid-project. Reading the permit history before design is the cheapest risk reduction available in this area.

How do I check my permit history?

Permit records for a property are available from the City of Los Angeles. Look for gaps rather than for entries: a room that appears on no permit, an addition with no final inspection, a foundation repair with no record. A contractor or designer familiar with the area will know how to read them, and it is worth doing before drawings begin rather than after.

Is my Northridge house on a slab?

Many are. Much of the area was built in the post-war decades as single-storey ranch houses on concrete slab-on-grade. It matters because moving a sink, shower or range on a slab means cutting and re-pouring concrete rather than working under the floor — the decision that most often explains why two estimates for the same kitchen differ so widely.

Should I add seismic retrofitting while I remodel?

If you are opening walls or working near the foundation anyway, that is the least expensive moment to consider it. Whether foundation bolting, cripple-wall bracing and hold-downs are already present varies house by house, including among houses repaired after 1994. Ask for it to be assessed as part of the survey rather than raised later as a change order.

Is Northridge good for an ADU?

Comparatively, yes. Lots tend to be larger, flatter and more regular than in the hillside communities to the south, which usually means a genuinely usable detached unit rather than a compromise, and equipment access to the rear without going through the house. Utility capacity for a second dwelling remains the item most often discovered late.

Do you perform the construction work?

Yes. Astrid Lind by Jacob Construction is the design studio of Jacob Construction Inc., a licensed California general contractor (CSLB #1073757, Class B).
