    • Estimate the construction cost with your hired contractors.
    • What is the potential value added to the housing that would cover its construction costs? Consult local estate agents to estimate the value-added.
    • Study your property from a desktop perspective. What lies on or below your site? Are there any nearby watercourses? Has flooding ever occurred in your area?
    • On narrow properties, retaining walls can be as thick as 700 mm, which may restrict basement floor space.

  • When You Don’t Require Planning Permission?

If you’re planning to convert your existing basement and don’t want to make any changes to the external appearance of the building, planning permission isn’t required.

Depending on the size, You don’t need planning permission for all extensions. Without planning permission, you can build up to 6 or 8 meters if your house is detached. At the same time, there are other rules where you don’t require permission:

    • No more than half of the land around the house can be covered by other buildings.
    • No extension can be forward elevation or side elevation in front of a highway.
    • No extension can be higher than the highest part of your roof.
    • Single storey extensions cannot extend beyond the rear wall of the original building by more than 8 meters.
    • Max height of a single-storey extension is 4 meters.
    • Extensions more than one storey can’t be extended beyond the rear wall by more than 3 meters of the house.
    • Two-storey extensions can’t be closer than 7 meters to the house rear boundary.
    • You can’t have balconies, verandas or a raised platform.
  • When You Need Planning Permission For Basement Extension?

However, you certainly need planning permission:

    • If you’re making any modifications or altering the external appearance of the property. And planning permission is also required if the building is in a conservation area or creating a separate unit of accommodation.
    • If you’re planning to add a lightwell, railings, or skylight at the front of your property (or anything that affects the external appearance of your house), you would need to apply for planning permission.
    • If your basement extension requires excavation to create more room which involves major work, you still also need planning permission for extension.
    • While making alterations, such as lowering the floor level to increase head clearance, contractors are likely to consider the extension plan. This is where they ask for planning permission.

A building construction in Los Angeles that violates any of the following conditions would also need planning permission and not be eligible for permitted development.

    • You’re building a new separate residence.
    • You live in a conservation area or your property is listed.
    • Your property is exempt from permitted development rights, for example, a flat, rather than a whole dwelling.

What Are The Planning Rules For Basement Extensions?

In the above sections, we’ve discussed in detail the basement extension planning permission. Now, we’re going to discuss some planning rules that every basement owner must take into account.

  • Consider Light Well For Basement Expansion

While planning for basement extensions, every homeowner must think about light wells. These are common features, spreading natural light and ventilation to the space- those are necessary for rooms like a bedroom or study room. So, before proposing a new light well or planning to extend the existing one, you need planning permission for a basement extension in Los Angeles.

Such interventions visible from the outside require a proper planning process. So, if possible, we recommend locating the light well to the rear or side of the house as there will be more design flexibility with regards to railings, appearance, and size. The light wells installed to the front will need to follow specific design rules where the size should be minimized and it may be necessary to install skylights or grilles instead.

Following a good landscaping design can minimize or soften the impact of a light well.

  • What Should Be the Maximum Extension?

The basement size depends on your council. That’s why it’s important to determine their certain design requirements and guidance.

There are strict limitations on the size of basements created in certain Los Angeles areas, where basement development is common. Standard criteria are now being applied by many Los Angeles areas, creating better policy consistency throughout the city.

    • A single-story building is allowed.
    • Basements are not permitted to be bigger than the footprint of the property plus 50% of the garden.
    • Local planning authorities will also consider the site’s characteristics. If existing trees or the water environment are at risk, the size of the project may be further restricted.
  • What Should be the Maximum Head Height For a Basement Room

Rules for maximum head height also depend on the council.

    • Every basement shall be in every part at least 2.5 meters in height from the floor to the underside of the roof slab or ceiling and with a maximum height of not more than 4.5 m.
    • To stay within building codes, you need at least 2 meters over the stairs. Remember to include in your calculations the height of your flooring.
    • Adequate ventilation shall be provided for the basement. One exhaust fan for a 50 sq m. basement area or air-conditioning system, etc.
    • The minimum height of the ceiling of any basement shall be 0.9 meters and a maximum of 1.2 mt. above the average road level on the front side of the building.
