Morro Bay Building Permit Guide for Custom Homes and Whole-Home Rebuilds

Planning guide · updated November 2026

Morro Bay sits on the San Luis Obispo County coast between Cayucos and Los Osos, with Embarcadero waterfront blocks, hillside streets above the Rock and quieter inland neighborhoods under City zoning. New custom homes here often replace an older house, and the City of Morro Bay — not the County — issues the planning and building approvals inside city limits. Here is how we plan a new home in Morro Bay so design review, the Coastal Development Permit path and Water Equivalency Unit rules are clear before drawings are final.

Harrod Built takes new custom homes and full rebuilds throughout San Luis Obispo County, including Morro Bay. Have a Morro Bay lot, an older house you intend to replace, or drawings that need a written estimate? Call 805-712-8993 or use the form farther down this page.

The short answer

Inside the City of Morro Bay, a new single-family home needs Community Development planning review under Title 17 before the Building Division will take a full plan check. Design review under Chapter 17.38 applies to new exterior construction, with larger single-unit projects heard by the Planning Commission and smaller ones decided by the Director, often filed together with other discretionary permits. Coastal Zone development generally needs a Coastal Development Permit under Chapter 17.39 of the certified Coastal Implementation Plan, with Director or Planning Commission review depending on scope and whether the location is appealable to the California Coastal Commission. New water users are regulated under Municipal Code Chapter 13.20 Water Equivalency Units, which generally must be allocated after planning approvals before a building permit can move. Building applications file through the City Community Portal with Electronic Plan Review. (we confirm per lot)

1. Offices on a Morro Bay new home

City planning, building, water and the coastal desk

Inside city limits, Planning and Building sit in the City of Morro Bay Community Development page, with building applications filed through the City of Morro Bay Community Portal. Fire-code and Public Works pieces route with the building set, and domestic water is a City system. This is how the work usually splits on a new Morro Bay house:

Drawn from the City of Morro Bay Community Development, Building Division, Planning Documents and Plan Morro Bay pages, the Building Permit Process flowchart, the Zoning Code and Coastal Implementation Plan (Title 17 Chapter 17.38 and Chapter 17.39), Municipal Code Chapter 13.20, the Water Division page and the California Coastal Commission coastal development permit page, read November 5, 2026.

A mailing address is not enough to pick the desk. Parcels just outside the city line go to the County of San Luis Obispo; our SLO County city-versus-County permits guide covers that split, and our SLO County coastal development permit guide covers coastal rules along the County shore. Our San Luis Obispo County hub and Morro Bay custom home page describe the homes we take on here, and we also work in nearby Cayucos, Los Osos, Cambria, Pismo Beach, Avila Beach and Arroyo Grande. Inland City of San Luis Obispo permits are a separate path; see our City of San Luis Obispo permit guide. (we confirm per lot)

3. Chapter 17.38 design review

Director path or Planning Commission hearing, often with the CDP

Chapter 17.38 of the Zoning Code and Coastal Implementation Plan requires design review for new construction and exterior work, with narrow exceptions for same-material replacements and work already covered by a prior design review approval. Larger single-unit projects go to the Planning Commission with public notice and a hearing; projects that do not meet those thresholds are decided by the Director, who may still refer a case to the Planning Commission when the public interest warrants it.

When a project also needs a Coastal Development Permit, Use Permit or Variance, design review files as part of that underlying application. Review looks at massing, site layout, landscaping, parking and related exterior features against Plan Morro Bay Community Character Areas and the City Residential Design Guidelines.

For a new house or a tear-down rebuild we treat the Director-versus-Planning Commission split as a schedule fact before schematic design locks height and floor area. (we confirm per lot)

5. City water and Water Equivalency Units

Chapter 13.20 rules when a rebuild adds new water use

The City of Morro Bay Water Division page delivers drinking water inside the City system and sustains fire-protection capacity. New construction that adds water users is also governed by the Building Limitation chapter of the Morro Bay Municipal Code: Chapter 13.20 Building Limitation regulates adding new water users so demand does not outrun supply.

Water Equivalency Units are the City’s accounting tool for that program. Units are allocated under an annual program, generally after required planning approvals, and a project that needs new units is not free to pull a building permit on hope of spare capacity. Allocated units run with the project and the property and are not transferable to another site.

We confirm whether the rebuild can rely on existing on-site water use or needs a new Water Equivalency Unit allocation before fixture counts freeze. (we confirm per lot)

7. Typical sequence

The order we use on a Morro Bay rebuild or new house

A frequent order for a new house or full rebuild inside Morro Bay city limits; coastal-appeals status, a bluff or habitat overlay, or a Water Equivalency Unit limit can each change it.

Our custom home timeline guide lays design, approvals and construction on one calendar. Nearby processes differ: our guides for Pismo Beach building permit guide, Monterey building permit guide, Carmel Highlands permit guide, Los Osos building guide, Carpinteria building permit guide, Goleta building permit guide, City of San Luis Obispo permit guide, SLO County city-versus-County permits guide, SLO County coastal development permit guide, Nipomo building guide, Santa Barbara Single Family Design Board guide, Montecito Board of Architectural Review guide, Montecito building guide, Hope Ranch guide, Santa Ynez Valley guide and Santa Barbara County building permits guide cover the neighbors.

How we help

Our role on a Morro Bay custom home or full rebuild

Harrod Built (CSLB #986950) is a family general contractor working in Monterey, San Luis Obispo and Santa Barbara counties. On a City of Morro Bay new house or whole-home rebuild, we typically handle:

• Early lot check. Title 17 zoning, design-review path, Coastal Development Permit and appeals status, Water Equivalency Unit needs and Building triggers, confirmed before we estimate.
• Estimates while plans move. Numbers while massing and materials can still shift under planning review.
• Demolition coordinated. Disconnects, demolition permitting and site protection arranged before the existing house comes down.
• Engineered site work. Soils, grading, foundation, drainage and frontage built from the approved set rather than allowances.
• City process support. Community Portal filings, planning package help, Water Equivalency Unit coordination and a tidy street frontage.
• Design support. Harrod Drafting & Design can draw the house and permit set, or we build from your architect’s plans.
• Landscape. Paso Robles Landscaping, our landscape company, handles planting, irrigation and hardscape to the approved plan, including fire-wise planting when mapped hazard rules require it.

Before hiring any builder, look up the license on the state license lookup; the CSLB’s advice on hiring a contractor and our article on how to check a CSLB license explain what to check. Nearby we also build in Morro Bay, Cayucos, Los Osos, Cambria, Pismo Beach, Avila Beach and Arroyo Grande, and across San Luis Obispo, Monterey and Santa Barbara counties, through general contracting or design-build. Our process page walks from estimate to move-in, and our contract type comparison explains fixed-sum and cost-plus agreements. For the local market, see our page on custom homes in Morro Bay and our hub for San Luis Obispo County custom home builders.
