Planning guide · updated October 2026
Building a house in Cambria, CA is different from building almost anywhere else on the Central Coast. Before anyone draws a floor plan, three things decide what is possible: whether the lot has water service from the Cambria Community Services District, what kind of lot it is under the County’s North Coast Area Plan, and how many Monterey pines stand where the house would go. This guide walks through those questions, the coastal permit path and the order of steps, for a new home, a teardown and rebuild, or a remodel of an existing Cambria home.
Harrod Built builds custom homes, remodels, additions and ADUs on the Central Coast, including in Cambria, San Simeon, Cayucos and across San Luis Obispo County. To talk through a lot, a teardown or a remodel, call 805-712-8993 or send the form at the end of this page.
The short answer
In Cambria, water comes first. The Cambria Community Services District declared a water shortage emergency in November 2001 that is still in effect, and it is not issuing new residential water or sewer connections. Remodels, rebuilds of existing homes, and lots with a grandfathered meter or an approved service transfer can still move ahead with a District Will Serve and Fire Plan Review. After water, the North Coast Area Plan sets the footprint and floor area a small lot can carry, the height limits and the setbacks, and the Monterey pine forest rules shape where the house sits. Permits run through San Luis Obispo County as a coastal permit, and many projects can be appealed to the Coastal Commission. Call 805-712-8993.
1. Where the rules come from
Cambria is County land, entirely in the coastal zone
Cambria is an unincorporated town, so homes are permitted by San Luis Obispo County Planning and Building, not by a city. The whole Cambria Community Services District (CCSD) service area sits inside the coastal zone. That means two layers of rules: the County’s Coastal Zone Land Use Ordinance (Title 23 of the County Code) and the North Coast Area Plan, which has its own Cambria Urban Area standards for lot size, building size, height, setbacks, trees, creeks and bluffs. Where the area plan and the countywide rules differ, the area plan standards for Cambria apply (we confirm per lot).
The County land use permit doubles as the coastal development permit. Under the area plan, most homes on typical lots go through a Plot Plan, while steeper lots, lots in the Lodge Hill Special Project Areas and homes that use transfer of development credits need a Minor Use Permit, which is a discretionary permit decided by a hearing officer. The CCSD notes that most development in Cambria is subject to appeal to the California Coastal Commission, and suggests applicants contact the Commission as part of their homework. Our coastal development permit guide explains exempt work, Plot Plans, Minor Use Permits and appeals across the SLO County coast; this guide stays on what is specific to Cambria.
The County’s Cambria page collects the Cambria documents: the area plan, the building size calculator and supplement, and the County waitlist. The North Coast planning area maps show land use categories and combining designations for each parcel.
2. Water service
The first question on any Cambria lot
Cambria’s water comes from District wells along San Simeon Creek and Santa Rosa Creek. According to the District’s water service FAQ, the Board declared a Water Code Section 350 water shortage emergency in November 2001 and put a moratorium on new connections, and that declaration has not been lifted. Its water positions and wait lists page says the District is not issuing any new residential or commercial water or wastewater connections. The District reports that it has not issued a new residential Intent to Serve letter after 2001, that hundreds of properties are on its wait list with no movement on the list, and that there is no timeline for lifting the moratorium. Current District priorities are permitting its Water Reclamation Facility and an instream flow study, which it says must come before any discussion of water for future growth.
| What the lot has | What it means today | What we check |
|---|---|---|
| An existing home with active CCSD water and sewer service | Remodels, additions and full reconstruction can go through the District’s Will Serve process. The District itself says the simplest way to build a new home in Cambria is to buy an existing home, take it down and build new. | The meter size, the District’s Will Serve and Fire Plan Review, and whether fire sprinklers need a larger meter. |
| A grandfathered meter on a vacant lot | A non-active service commitment from before the 2001 emergency, still connected to the system. The District lists these as eligible for a Will Serve without an Intent to Serve letter. | That the lot appears on the District’s existing commitment list and the billing that keeps the status current. |
| An Intent to Serve letter from before the moratorium | Honored if it was issued before the moratorium and kept current through extensions under the District code. | The letter’s conditions and deadlines, and whether it is on the District’s current or suspended list. |
| A position on the CCSD wait list only | A place in line to apply when the position becomes eligible. The list has not moved after the November 2001 emergency, and the District gives no timeline. | The position number, and whether it is a CCSD position or a County building permit waitlist position, which is a separate list. |
| No water position at all | The District calls a future water permit questionable. Today the only path is a transfer from another parcel that already has a position, with limits on which lots can receive one. | Whether a transfer is even allowed to this lot, based on its size and location. |
Summarized from the Cambria Community Services District water service FAQ, water positions and wait lists, wait list, Will Serves and Retrofits, and transfers pages, checked October 23, 2026. The District, not the seller or the listing, confirms a lot’s status.
Wait lists: two lists, not one
The CCSD wait list was set up in 1986 and closed to new applications at the end of 1990, per its wait list page. The County keeps its own waitlist for vacant Cambria parcels, and the County notes that the CCSD list is served first; see the County single-family waitlist. The County also sets Cambria’s growth allowance, and the District says the current allowance is zero. If a listing says a lot has “a wait list position,” the District advises confirming whether it is a CCSD water position or a County building permit position.
No off-grid workaround
The District states that the County will not process a building permit for a project without water, including homes designed to be off-grid with rainwater or atmospheric water. Inside the CCSD service area, homes must be served by District water and sewer under the Local Coastal Program, and private wells for drinking water are not allowed. Positions, letters, grandfathered meters and active service can move between eligible parcels under the District code, but transfers cannot go to lots under 3,500 square feet or into the Lodge Hill Special Project Areas; see the transfers and assignments page. For a buyer, the water status is worth confirming with the District, in writing, before the purchase closes (we confirm per lot).
3. Will Serve, Fire Plan Review and retrofits
What remodels and rebuilds need from the District
The County requires a CCSD Will Serve letter for every project that uses District water or sewer, plus a Fire Plan Review from the Cambria Fire Department, which is part of the District. The North Coast Area Plan makes both part of the application: the County will not accept a land use or building permit application without written verification of water and sewer service and a fire plan review, and a District compliance letter is needed before final building inspection. Per the District’s Will Serves and Retrofits page, the Will Serve path covers remodels and reconstruction of existing homes and new construction that uses a grandfathered meter or an active service transfer. Applications are filed online with the District.
Fixtures and meters
The District’s review looks at the plumbing fixtures a project adds, such as sinks, toilets, showers, tubs and clothes washers, so the fixture count is part of the plan from the start. Some projects need a larger meter or a meter in a new spot, often to meet fire sprinkler flow; the District has a water service change request for that. We work out the sprinkler design and the meter question together, early, because the meter is not something to discover at the end.
Retrofits
The District’s retrofit program has three parts: retrofit upon resale, retrofit requirements for remodels and additions, and water use efficiency rules for new construction. When a Cambria home changes hands, the code requires it to be fitted with high-efficiency plumbing fixtures if it is not already. New construction has to offset its water demand through retrofit points or by retrofitting older fixtures elsewhere in the District, with the points based on lot size and the number of bathrooms. EPA WaterSense fixtures can meet the rules, but the District warns that some labeled fixtures still exceed its limits, so we check each fixture against the District guide.
4. Small lots
Footprint, floor area, height and setbacks
Much of Cambria was laid out after a 1927 land sale as small subdivisions of 25-foot-wide lots: Lodge Hill, Happy Hill, Park Hill and Pine Knolls. The CCSD notes that many single lots are only 1,750 square feet. Homes in these small-lot neighborhoods follow Table 7-1 of the North Coast Area Plan, which caps two numbers based on the lot size and the lot type:
- Footprint: the area covered by the house, garage, carport and accessory buildings, including structural overhangs but not open decks, balconies or eaves.
- Gross structural area (GSA): all interior floor area, including living space, storage, garage and carport, measured to the outside of the walls.
The lot types are Special Project Area 1 (Fern Canyon, steep canyon), Special Project Area 2 (visible hillside), forested lots (with one or more native Monterey pines of a set trunk size), steep lots, marine terrace lots near the bluffs, and typical lots. Each type and lot-size band carries its own limits, adjusted in proportion for lots between the base sizes, and forested, steep and canyon lots get less than typical or marine terrace lots. A few tracts are outside Table 7-1 and follow their own rules (we confirm per lot).
The County’s Cambria Building Size Calculator works the numbers, and the Cambria Residential Building Size Supplement asks for the pines on the site, the slope, whether the lot is visible from Highway 1, the lot type, the footprint, the GSA, decking, height, trees proposed for removal and the water connection. We run those numbers before design starts, because on a single or double lot they decide the size of the house more than the budget does.
Transfer of development credits and lot mergers
The area plan’s transfer of development credits program lets an owner of a small lot in East or West Lodge Hill, Park Hill, Happy Hill or Pine Knolls add footprint and GSA by paying to retire a lot in a sensitive area, such as Fern Canyon, the visible hillside or dense pine forest. The program is run through the Land Conservancy of San Luis Obispo County or another approved administrator, needs a Minor Use Permit, and may not be available everywhere. Credits cannot be used on very steep lots or sites with wetlands, rare species habitat or cultural resources. Owning two or three adjoining lots as one legal lot also moves the house into a larger lot-size band.
Height
The general limit for single-family homes in Cambria is 28 feet above average natural grade, with lower limits in some areas: 25 feet for homes visible from Highway 1 in Lodge Hill, 22 feet on the marine terrace between Marlborough and Sherwood, 15 feet between Highway 1 and the ocean along Moonstone Beach, and 15 feet above the centerline of the road for oceanside lots on parts of Nottingham Drive, Windsor Boulevard and Sherwood Drive. On sloping lots, much of the downhill face is held to a lower height with the next story stepped back, unless a Minor Use Permit approves a well-articulated alternative. Our second story guide covers the structural side of building up.
Setbacks, parking and walls
On lots under an acre, front and rear setbacks must add up to 25 feet, with at least 10 feet at each, and narrow lots under 50 feet wide keep 3-foot side setbacks (5 feet on a street corner side), with exceptions on certain streets and tracts. Each home needs two off-street parking spaces, at least one covered. Exposed retaining walls for driveways and site work are held to six feet, with stepped terraces preferred, and long driveways stay narrow except where the fire department needs more. Minor Use Permit applications also include a streetscape drawing showing the two homes on each side and a statement on how the design meets the area plan’s design criteria: a small-scale look from the street, no more than two stories to the street, garages that do not dominate, and drainage kept on site.
5. Monterey pines and oaks
The forest shapes where the house goes
Monterey pine forest covers most of the Cambria Urban Area, and the area plan treats it as sensitive habitat. On a forested lot, the County may require a biological report after a site review, and every project sets a “project limit area” on the least sensitive part of the lot. That area has to hold everything: the house, grading, utility trenches, fire clearance, staging and material storage. Native vegetation outside it stays put, except trees a qualified professional finds hazardous.
- Plans. Site, grading and construction plans show every Monterey pine and oak above a set trunk size, which ones stay and which are proposed for removal, with sturdy protective fencing along the project limit area for the whole job.
- During construction. No stockpiling within 15 feet of a tree, utility trenching inside driplines dug by hand, compacted root zones aerated, and only a limited share of any kept tree’s dripline disturbed. When remodeling or replacing a home, the plan favors keeping the existing driveway where moving it would hurt trees.
- Replacement. Each Monterey pine removed is replaced four to one, and each oak six to one, with native Cambria-stock pines, under a replanting plan approved before the building permit. A nursery or landscape professional confirms the planting before final inspection, and the planting is monitored for at least three years.
- Notice and pitch canker. Where a Plot Plan covers tree removal, a notice is posted at the front of the lot. Diseased material is handled under the plan’s pitch canker and bark beetle rules.
In practice, the trees and the lot type together often set the footprint before the architect draws the house, and they drive staging on narrow Lodge Hill streets. Paso Robles Landscaping, our landscape company, can plan replanting and fire-wise planting that fits the forest rules.
6. Creeks, bluffs and coastal appeals
Lots near Santa Rosa Creek or the ocean
New development near Santa Rosa Creek is set back at least 100 feet from the upland edge of riparian vegetation, with smaller setbacks only under the County’s coastal habitat rules, and filling or channelizing the creek’s floodway is prohibited. The area plan also limits new development in flood hazard areas. On blufftop lots, an engineering geology report sets a bluff setback meant to last a century of erosion, never less than 25 feet, and new homes cannot rely on a new seawall; owners record a deed restriction against future shoreline protection. Large additions to an existing blufftop home that does not meet the setback can require bringing the whole house into conformance (we confirm per lot).
The Coastal Commission appeal information sheet explains which local coastal permits can be appealed: among them, development between the sea and the first public road, within 300 feet of a beach, within 100 feet of a wetland or stream, or within 300 feet of a coastal bluff. Every local appeal has to be used first, per the County’s coastal appeal page. Parts of Cambria are also mapped as archaeologically sensitive, which can add a survey. Our guide to coastal development permits in SLO County walks through appeal timing.
7. Fire
Pine forest, hazard zones and access
The area plan notes a high fire danger across the community because of the forest, slopes, narrow roads and limited evacuation routes. The Cambria Fire Department reviews plans before the County accepts an application. The State Fire Marshal’s local responsibility area map for unincorporated San Luis Obispo County, dated March 2025, shows Moderate, High and Very High fire hazard severity zones; check the parcel through the County Fire fire hazard severity zone page, which links to the state viewer. A home in a mapped zone is built to Chapter 7A of the California Building Code, with ember-resistant roofs, vents, siding, windows and decks; see our guide to building in a fire hazard severity zone.
Defensible space matters here too. In a High or Very High zone, a seller of a home built before 2020 needs documentation of a compliant defensible space inspection. The state Board of Forestry has been writing rules for “Zone 0,” the first five feet around a home; the County Fire Zone 0 FAQ explains the proposal, and we check where it stands for each project (we confirm per lot). Under the forest rules, understory clearing for fire safety is kept to the minimum needed, and clearing without a permit can trigger replanting requirements.
8. Remodeling a Cambria home
Additions, rebuilds and keeping the water
Because new connections are closed, an existing home with active service is valuable. Remodels, additions and full reconstruction go through the District’s Will Serve and Fire Plan Review, and the County decides whether the work is exempt or needs a coastal permit. Interior work that adds no floor area or height is often exempt from a coastal permit but still needs a building permit; see our remodel permit guide. An addition counts against the lot’s footprint and GSA limits, so on a small lot the first question is how much area is left under Table 7-1. Added bathrooms and fixtures go through the District review, and a home that changes hands is retrofitted with high-efficiency fixtures.
A teardown and rebuild keeps the water service if it is done through the District’s process, but the new house follows today’s area plan limits, not the old house’s size (we confirm per lot). Adding a second unit runs into the same water rules; our SLO County ADU guide covers ADUs, and the District should confirm water for any added unit before design.
9. Planning the schedule
A realistic order of steps
| Step | What happens | What usually sets the pace |
|---|---|---|
| Water and lot check | CCSD water and sewer status, lot size and lot type under the North Coast Area Plan, Special Project Area, pines and oaks, creek or bluff, fire hazard zone, survey and the permit history of what is already built. | Whether the lot can get water at all, and whether old work was permitted. |
| Site studies | Topographic survey, tree survey, soils report, and where needed a biologist, arborist, engineering geologist or archaeologist. | Consultant schedules. |
| Early design | Footprint and gross structural area from Table 7-1, height and setbacks, parking, retaining walls, and a design that keeps the trees outside the project limit area. | How tight the lot is and how many trees are near the house site. |
| District letters | CCSD Will Serve and Cambria Fire Department Fire Plan Review, needed before the County accepts the application. | How complete the plans are when the District reviews them. |
| Coastal permit | A Plot Plan or a Minor Use Permit with the County, which also serves as the coastal development permit, with any noticing and appeal period. | Level of review, neighbor interest and any appeal. |
| Construction drawings and plan check | Structural, energy, fire sprinkler and Chapter 7A details, grading and drainage, tree protection and replanting plans. | Plan check corrections and resubmittals. |
| Construction and final | Tree fencing, construction, inspections, the District’s compliance letter, the replanting letter and final inspection. | Weather, inspections and access on narrow streets. |
The order we plan a Cambria project in. A simple interior remodel may skip several steps; a forested, steep or blufftop lot can add more.
The Cambria projects that move most smoothly start with the water status, the lot type and the tree survey, not the floor plan.

10. Before you buy or design
12 questions to answer about a Cambria lot
- Does the lot have active CCSD water and sewer service, a grandfathered meter, an Intent to Serve letter, a wait list position, or nothing?
- If it has a wait list position, is it a CCSD position or a County position?
- Is it one legal lot, or several small lots held together?
- Which Table 7-1 lot type is it: typical, forested, steep, marine terrace, or a Special Project Area?
- What footprint and gross structural area does that allow, and how much is already used?
- Which height limit applies, and is the lot visible from Highway 1?
- How many Monterey pines and oaks are near the likely house site?
- Is it near Santa Rosa Creek, a bluff or the beach, and is it in the appeal area?
- Which fire hazard severity zone is it in, and can an engine reach it?
- Will fire sprinklers need a larger meter?
- Does what is built today match the permits on file?
- Is there room on the lot and street for parking, staging and tree protection during construction?
If you have an architect already, we work from their drawings. If not, Harrod Drafting & Design can draw the house and the permit set.

Can I build a new house on a vacant lot in Cambria?
Only if the lot can get water. The Cambria Community Services District has had a water shortage emergency in place from November 2001 and is not issuing new residential connections. A vacant lot with a grandfathered meter, a valid pre-moratorium Intent to Serve letter or an approved service transfer may be able to build; a lot with only a wait list position, or none, generally cannot for now.
Can I remodel or rebuild an existing home in Cambria?
Yes. Remodels, additions and reconstruction of existing homes with District service go through a CCSD Will Serve and a Cambria Fire Department Fire Plan Review, then the County permit. The new work must fit the North Coast Area Plan limits for footprint, floor area, height and setbacks.
How big a house can I build on a Cambria lot?
In the small-lot neighborhoods such as Lodge Hill, Park Hill, Happy Hill and Pine Knolls, Table 7-1 of the North Coast Area Plan caps the footprint and gross structural area based on lot size and lot type: typical, forested, steep, marine terrace or a Special Project Area. The County’s Cambria Building Size Calculator works out the numbers.
Can I cut down Monterey pines to build in Cambria?
Only as part of an approved project. Plans must show every pine and oak above a set size, the house has to fit inside a project limit area that avoids the forest as much as possible, and each pine removed is replaced four to one with native stock under a replanting plan.
Who issues building permits in Cambria?
San Luis Obispo County Planning and Building. Cambria is unincorporated and entirely in the coastal zone, so the County land use permit also serves as the coastal development permit, and many decisions can be appealed to the California Coastal Commission. The Cambria Community Services District handles water, sewer and fire plan review but does not issue building permits.
