Property exposure brief
The balcony nobody uses
The one chair is open for morning coffee 12:00 AM to 8:00 AM.
The property, as mapped
The balcony nobody uses at Los Angeles (demonstration). 1 places are being read, against 3 things that stand in the way.
| The building | 85.3 ft | 100 per cent solid. Confirmed. |
|---|---|---|
| Glass balustrade | 62.7 ft | 95 per cent solid. Confirmed. |
| The tower opposite | 111.5 ft | 100 per cent solid. Confirmed. |
How The one chair behaves in September
The one chair is open for morning coffee 12:00 AM to 8:00 AM.
About 8 hours in September, and wind is what closes it.
The sun reaches this spot from 7:00 AM and leaves it at 7:00 PM. At 3:28 PM it goes into shade because of The tower opposite. At 6:22 PM it goes into sun because of The tower opposite.
| Direct sun | 9.3 hours | of 12.3 hours of daylight |
|---|---|---|
| Sky visible from here | 51 per cent | The building takes 87%, The tower opposite takes 13% |
| Usable light | 26.4 mol/m² a day |
Whether it works for morning coffee
The one chair is on the edge for morning coffee right now, and wind is why.
| Wind | 13.1 mph against at most 7.8 mph | Cold air moving early is what sends people back inside. |
|---|
Privacy and view
Every marked line into this seat is already interrupted. Privacy reads 5 out of 100 here, and nothing needs building.
| Add 0.4 ft to glass balustrade | 63.1 ft | Privacy 5 → 5, view 46 → 24. Closes every marked line. your land. |
|---|
What to try, cheapest first
Nothing tested moves this materially, which usually means the limit is real rather than fixable by an object.
| Two 8.2 ft parasols instead of one | +0 | move it. It does not meaningfully change the beam in either season. |
|---|---|---|
| A 9.8 ft umbrella | +0 | an afternoon. It does not meaningfully change the beam in either season. |
| Two low shielded lights instead of one high one | +0 | an afternoon. It does not meaningfully change the beam in either season. |
| A shade sail over the seating | +0 | a project. It does not meaningfully change the beam in either season. |
| A 5.9 ft porous windbreak upwind | +0 | a project. It does not meaningfully change the beam in either season. |
| A 6.9 ft panel to the east | +0 | a project. It does not meaningfully change the beam in either season. |
What survives out here
Things stay wet here for 6 months of the year. That, and not rainfall, is what decides what survives. Natural rattan, jute and untreated rope is the family this place punishes hardest. Family behaviour is a starting point. The exact product still decides the outcome.
| Tempered glass | well suited | Anything that stays damp grows something, whatever it is made of. Ask the supplier: What is the edge detail, and how will it be cleaned on the outside face? |
|---|---|---|
| Exterior porcelain paver | well suited | Anything that stays damp grows something, whatever it is made of. Ask the supplier: What is the slip classification, wet, and how is it being laid: pedestals, sand or mortar? |
| Stainless steel | well suited | Salt air changes which metals and which grades of metal are viable, not just how often you wash them. Ask the supplier: Is it 304 or 316? Within a few miles of salt water that difference is the whole decision. |
| Gravel and self-binding aggregate | well suited | Anything that stays damp grows something, whatever it is made of. Ask the supplier: What size and shape is the aggregate, and is there an edge to keep it where it belongs? |
| HDPE and polypropylene resin furniture | well suited | This spot takes about 1.04 MJ per square metre a day of ultraviolet in its harshest month. Ask the supplier: Is it ultraviolet-stabilised, and what does the fade warranty say in years? |
| Powder-coated aluminium | well suited | This spot takes about 1.04 MJ per square metre a day of ultraviolet in its harshest month. Ask the supplier: Is the powder coat rated to AAMA 2604 or 2605, and is the substrate marine-grade? |
What belongs here
About 29.2 moles of usable light a day with about 9 hours of direct sun in high summer. That is full sun, whatever the label on the plant says.
Nothing in the reference set is a clean match here, which usually means the light or the drainage has to change first. Anything planted here sits wet for 6 months of the year, so drainage is the decision before the plant is.
| Rain garden and swale planting | will work | Zone 10.2 is outside this group's usual range of 3 to 9. Hardiness is a floor, not a plan. Examples, not recommendations: Iris in damp ground; Switchgrass; Joe Pye weed in North America. |
|---|---|---|
| Moisture-loving marginal | will work | Zone 10.2 is outside this group's usual range of 3 to 9. Hardiness is a floor, not a plan. Examples, not recommendations: Astilbe; Ligularia; Iris sibirica. |
| Narrow upright evergreen screen | wrong place | This spot sits wetter than this group tolerates. Wet feet kill far more plants than cold does. Examples, not recommendations: Columnar hornbeam; Italian cypress in mild dry climates; Upright yew in cool climates. |
| Broad evergreen hedge | wrong place | This spot sits wetter than this group tolerates. Wet feet kill far more plants than cold does. Examples, not recommendations: Yew; Portuguese laurel; Holly. |
| Deciduous hedge that holds its leaves | wrong place | This spot sits wetter than this group tolerates. Wet feet kill far more plants than cold does. Examples, not recommendations: Beech; Hornbeam. |
| Medium deciduous shade tree | wrong place | This spot sits wetter than this group tolerates. Wet feet kill far more plants than cold does. Examples, not recommendations: Field maple; Serviceberry; Hop hornbeam. |

Where this stops
- Any freestanding barrier above about two metres carries real wind load into its footings and is likely to need consent. That is an engineer's calculation and a planning question, not a design one.
- Anchoring and wind rating are the manufacturer's numbers, not ours. A cantilever umbrella in gusty conditions is a real hazard.
- Permanent exterior circuits need code-compliant wiring.
- Sail tension pulls hard on its anchors. Fixing points into a wall, a post or a tree is a structural decision.
- Anything tall enough to shelter a terrace is carrying real wind load into its footings.
- A tall panel in an exposed place is a sail, and it needs footings sized for it.
- This is a decision instrument. It models sun, shade, sightlines, radiant heat and drying from the geometry it was given. It is not a structural, drainage, electrical or planning assessment, and it does not replace one.
Who to ask, and what to ask them
Everything this reading cannot answer goes to 7 places: a structural engineer, a drainage engineer, an electrician, your planning authority, an arborist, a pool or spa installer and the manufacturer.
Inferred from the time zone America/Los_Angeles. A time zone identifies a country reasonably well and a county not at all, so nothing below is local to you.
A licensed professional engineer (PE), structural
Whether a wall, deck, post or fixing carries the thing you are proposing is a calculation about materials and connections. This product models sun, wind exposure and sightlines; it has never been told what the wall is made of or how the deck is framed.
Take these questions
- Will this fixing or footing carry the load, in the wind this site actually gets?
- What has to be opened up or exposed before that can be answered?
- Is there a version of this that avoids a structural question altogether?
Take these with you
- The contractor packet from this property, which has the dimensions and where each came from
- Photographs of the wall or frame the thing would fix to
- Anything you know about what is behind the surface
Where the register is
NCEES — licensure and verification — Licensing is by state; this points at the board that holds your state's register.

A drainage contractor or civil engineer
This product reads how long a surface stays wet from sun, shelter and shade. It does not know where the water goes afterwards, what the ground is made of below the top few inches, or what your drains are connected to.
Take these questions
- Where is this water going now, and where would it go after the change?
- Is there a connection or a soakaway involved, and is that something I am allowed to alter?
- What would a percolation or infiltration test cost here before anybody designs anything?
Take these with you
- The wetness reading and the months it is worst in
- Where the downspouts land and where water stands after rain
- Any drainage drawing that came with the property

- This is a decision instrument. It models sun, shade, sightlines, radiant heat and drying from the geometry it was given. It is not a structural, drainage, electrical or planning assessment, and it does not replace one.
A licensed electrician
Outdoor lighting and anything powered near water is a wiring question with a legal answer, and this product models the light rather than the circuit.
Take these questions
- Is this circuit suitable for outdoors and for the distance involved?
- What protection does this need, and does the work have to be certified or inspected?
- Can the fixture be aimed or shielded the way I need without changing the wiring?
Take these with you
- Where the fixtures would go and what they are pointed at
- The distance from the nearest existing supply
Where the register is
Your state or county building department — Permitting and licence checks are local; the state consumer office lists who holds them.

- Permanent exterior circuits need code-compliant wiring.
- This is a decision instrument. It models sun, shade, sightlines, radiant heat and drying from the geometry it was given. It is not a structural, drainage, electrical or planning assessment, and it does not replace one.
Your city or county planning and building department
Whether you are allowed to build a thing is decided by a local rule set that varies street by street. This product has no idea which rules apply to your address, and anything it said about consent would be a guess dressed as an answer.
Take these questions
- Does this need consent at this height, this footprint and this distance from the boundary?
- Is there anything specific to this property — a conservation designation, a covenant, an easement, an HOA rule?
- If it does not need consent, is there anything that would make it need one?
Take these with you
- The dimensions and the position relative to the boundary, which the contractor packet already states
- A site plan showing where it sits
- The property address, which is what everything above is actually keyed to
Where the register is
USA.gov — find your local government — Permits and setbacks are city or county; this finds the office that issues them.

A certified arborist
This product models a canopy as a shape that blocks light. Whether a tree is safe, whether it will survive what you are proposing, and whether you are permitted to touch it are three separate questions it cannot answer.
Take these questions
- Is this tree safe as it stands, and does the answer change if I build near it?
- What will this do to the root zone, and how far out does that reach?
- Is this tree protected, and by what?
Take these with you
- The canopy dimensions this product is using and where they came from
- Photographs of the whole tree, including the base
- What you are proposing to build and how close
Where the register is
ISA — find an arborist — The certification register, including the tree-risk qualification.
The line in this document that sends you here
- Sail tension pulls hard on its anchors. Fixing points into a wall, a post or a tree is a structural decision.
A pool or spa installer, plus your building department for barrier rules
This product reads the air, the light and the sightlines around water. Electrical bonding, barrier law, deck loading and water chemistry are all outside it, and each of them is a safety question rather than a comfort one.
Take these questions
- What does the deck have to carry with this full and occupied?
- What barrier or fencing rule applies at this address?
- What has to be bonded, and who signs that off?
Take these with you
- Where it would sit and what it sits on
- The distance to the nearest supply and to the boundary
Where the register is
CPSC — pool and spa safety — Barrier and entrapment guidance; local code still decides.
The line in this document that sends you here
- Any freestanding barrier above about two metres carries real wind load into its footings and is likely to need consent. That is an engineer's calculation and a planning question, not a design one.
The manufacturer or an approved installer
Wind ratings, fixing patterns and warranty conditions belong to whoever made the thing. This product can say what a change would do to the reading; it cannot say what voids the guarantee.
Take these questions
- What is the wind rating, and in what mounting?
- What does the warranty require of the installation and the maintenance?
- What is the actual lead time and what does it look like in five years?
Take these with you
- The exposure this product measured, including the windiest month
- The fixing surface you actually have
No register is named here, because this router does not know which country holds one for you. The questions above are the same wherever you are.
The line in this document that sends you here
- Anchoring and wind rating are the manufacturer's numbers, not ours. A cantilever umbrella in gusty conditions is a real hazard.
Nothing here says what the answer will be. These are registers rather than recommendations, and a name on one is a qualification rather than an endorsement.
